Ball valves were introduced in the 1950s. With the rapid development of science and technology, the continuous improvement of production technology and product structure has rapidly developed into a major valve category in just 40 years. In countries with developed industries in western countries, the use of ball valves is increasing year by year. In China, ball valves are widely used in petroleum refining, long-distance pipelines, chemical, paper, pharmaceutical, water conservancy, electric power, municipal, steel and other industries. It plays a pivotal role in the national economy.
The ball valve is mainly used to cut off or turn on the medium in the pipeline, and can also be used for fluid regulation and control. The hard seal V-ball valve has a strong V-shaped ball core and the metal valve seat of the hardfacing alloy. Shear force, especially suitable for media containing fibers, tiny solid particles. The multi-way ball valve not only can flexibly control the confluence, splitting, and flow direction switching of the medium, but also can close any channel and connect the other two channels.
The function of the ball valve The ball valve has a rotation of 90 degrees, the body of the plug is a sphere, with a circular through hole or passage through its axis. The ball valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. It only needs to be rotated 90 degrees and the torque can be closed tightly. The ball valve is suitable for use as a switch or shut-off valve, but recent developments have designed ball valves to provide throttling and control flow, such as V-ball valves.
The main features of the ball valve are its compact structure, reliable sealing, simple structure and convenient maintenance. The sealing surface and the spherical surface are often closed, not easily eroded by the medium, easy to operate and maintain, suitable for general work such as water, solvent, acid and natural gas. Medium, but also suitable for medium with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, which are widely used in various industries. The ball valve body may be integral or combined.
The main advantages of the ball valve
1. The fluid resistance is small, and the full-bore ball valve has substantially no flow resistance.
2. The structure is simple, small in size and light in weight.
3. Tight and reliable. It has two sealing faces, and the sealing surface material of the ball valve is widely used in various plastics, and has good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems.
4. The operation is convenient, the opening and closing is rapid, and the rotation is 90° from full opening to full closing, which is convenient for long-distance control.
5. The maintenance is convenient, the ball valve has a simple structure, and the sealing ring is generally movable, and the disassembly and replacement are relatively convenient.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium does not cause erosion of the sealing surface of the valve.
7. Wide range of applications, from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied.
8. Since the ball valve is wiping during opening and closing, it can be used in a medium with suspended solid particles.
Ball valve classification and characteristics Ball valve has manual ball valve, electric ball valve, pneumatic ball valve, high pressure ball valve, high temperature ball valve, three-way ball valve, thermal ball valve, low temperature ball valve, thread ball valve, flange ball valve, welding ball valve, ball valve, butt ball valve, Card sleeve ball valve, clamp ball valve, floating ball valve, fixed ball valve, hard seal ball valve, soft seal ball valve, socket solder ball valve, stainless steel ball valve, etc.
1. The ball of the floating ball valve is floating. Under the action of the medium pressure, the ball can generate a certain displacement and press on the sealing surface at the outlet end to ensure the sealing of the outlet end. The floating ball valve has a simple structure and good sealing performance, but the load of the ball subjected to the working medium is all transmitted to the outlet sealing ring, so it is necessary to consider whether the sealing ring material can withstand the working load of the spherical medium, and when subjected to a high pressure shock. The sphere may be offset. This structure is generally used for medium and low pressure ball valves.
2. The ball of the fixed ball valve is fixed, and does not move after being pressed. The fixed ball valve has a floating valve seat. After the medium pressure, the valve seat moves, so that the sealing ring is pressed against the ball to ensure the seal. Usually mounted on the upper and lower shafts of the ball, the operating torque is small, suitable for high pressure and large diameter valves.
In order to reduce the operating torque of the ball valve and increase the reliability of the seal, oil seal ball valves have appeared in recent years, and the special lubricating oil is injected between the sealing faces to form an oil film, which enhances the sealing performance and reduces the operating torque. It is more suitable for high pressure and large diameter ball valves.
3, elastic ball valve (ie track ball valve)
The ball of the ball valve is elastic. Both the ball and the seat ring are made of metal material, and the sealing pressure is very large. The pressure of the medium itself cannot meet the sealing requirements, and an external force must be applied. This valve is suitable for high temperature and high pressure media.
The elastic sphere is made by opening an elastic groove at the lower end of the inner wall of the sphere to obtain elasticity. When the passage is closed, the wedge of the valve stem is used to open the ball and press against the seat to seal. Before the ball is rotated, the wedge head is loosened, and the ball is restored to its original shape, so that a small gap occurs between the ball and the valve seat, which can reduce the friction and operating torque of the sealing surface.
4, V-type ball valve This kind of ball valve belongs to the fixed ball valve, is also a single valve seat sealed ball valve, the adjustment performance is good in the ball valve, the flow characteristics are equal percentage, the adjustable ratio is up to 100:1. Its V-shaped slit has shearing action with the metal seat, especially suitable for media containing fibers, tiny solid particles, slurry.
5, three-way ball valve three-way ball valve has T and L type. The T-type enables three orthogonal pipes to communicate with each other and cut off the third channel to function as a split and merge. The L-shaped can only connect two pipes that are orthogonal to each other, and cannot simultaneously maintain the mutual connection of the third pipe, and only serves as a distribution.
1. Three-way ball valve adopts integrated structure in structure, sealed type of 4-sided valve seat, less flange connection, high reliability, and light weight in design.
2. The three-way ball core is divided into T type and L type, with long service life, large circulation capacity and low resistance.
3. The ball valve is divided into two types according to the action type: single action and double action. The single action type is that the ball valve will be in the state required by the control system once the power source fails.
Ball valve operation and use
1) Make sure the lines and valves have been flushed before operation.
2) The operation of the valve is driven by the actuator input signal to complete the rotation of the valve stem: when the forward rotation is 1/4 turn (90°), the valve is closed. The valve opens when rotated 1/4 turn (90°) in the opposite direction.
3) When the actuator direction indicator arrow is parallel to the pipeline, the valve is open; when the indicator arrow is perpendicular to the pipeline, the valve is closed.
1. The ball valve is automatically opened in the distance. Under the premise that the PLC has no fault, no sensor fault signal, the ball valve and the control system are in the normal closed state, the ball valve is automatically opened by the LCU to the ball valve control cabinet.
2. The ball valve is automatically opened on the premise that the PLC has no fault, no sensor fault signal, the ball valve and the control system are in the normal closed state. Press the open ball valve button on the ball valve control cabinet, and the ball valve will automatically open.
3, manually open the ball valve manual action 52DPK, make the bypass valve open; observe the pressure gauge, in the appropriate state, manual action 53DPK, 54DPK, retreat work, repair seal, manual action 51DPK in place to make the ball valve relay action The ball valve is opened; after confirming that the ball valve has been fully opened, the manual action 52DPG, the bypass valve is closed. After confirming that the bypass valve is closed, the ball valve opening process ends.
4. The remote automatic closing ball valve will issue the ball valve command to the ball valve control cabinet through the unit LCU without fault and the ball valve is in the normal open state, and the ball valve will automatically close.
5. Automatically close the ball valve on the spot. Under the premise that the PLC is not faulty and the ball valve is in the normal open state, press the close ball valve button on the ball valve control cabinet, the ball valve will automatically close.
6. Manually close the ball valve manual action 51DPG, make the ball valve relay act, the ball valve is closed; after confirming that the ball valve has been completely closed, manually operate 53DPG, 54DPG, cast work, repair and seal. After the confirmation is completed, the ball valve closing process ends.
7. Crossing the PLC emergency shut-off ball valve In the case of PLC failure in the ball valve control cabinet (unit LCU ball valve PLC fault signal), and requiring the accident to close the ball valve, the emergency ball valve switch on the LCU disk can be operated to close the ball valve and put in Work sealed. Reset the emergency ball valve switch in time after the ball valve is closed.
The ball valve temperature and pressure nameplates show the large operating pressures allowed by the ball valve at the small operating temperatures of Zui Da and Zui.
Valve seats and seals made of PTFE or RTFE are used. The operating temperatures of other types of seats and seals are subject to inspection by the KI factory.
The nominal pressure rating (PN) of the valve indicates the large working pressure of the valve at normal temperature. (Example: PN4.0, indicating that the operating temperature of zui at -290C to 380C is 40Bar (4.0MPa)).
Ball valve installation matters
1) Remove the protective cover on both sides of the flange end and clean it with the valve fully open.
2) Before installation, the whole machine test should be carried out according to the specified signal (electricity or gas) (to prevent the use of vibration due to transportation). After passing the test, it can be installed on the line (wiring according to the electric actuator circuit diagram).
3) Flush and remove any remaining impurities in the piping (which may damage the seat and ball) before preparing to connect to the pipeline.
4) During installation, do not use the actuator part of the valve as a lifting point for lifting to avoid damage to the actuator and accessories.
5) This type of valve should be installed in the horizontal or vertical direction of the pipe.
6) Pipes near the installation point should not be drooped or subjected to external forces. Pipe supports or supports can be used to eliminate the deviation of the pipeline.
7) After connecting with the pipe, cross-tighten the flange connection bolt with the specified torque.
Ball valve repairs have a long service life and maintenance-free period and will depend on several factors: normal operating conditions, maintaining a harmonious temperature/pressure ratio, and reasonable corrosion data.
â— When the ball valve is closed, there is still a pressurized fluid inside the valve body. â— Before the maintenance, the line pressure is released and the valve is in the open position. â— Before the maintenance, disconnect the power or air supply. â— Before the maintenance, disengage the actuator from the bracket. â— Firstly, it is necessary to remove the decomposing operation after the upper and lower pipes of the ball valve have been removed. â— The sealing surface of the damaged parts must be carefully prevented during the disassembly and reassembly. Especially for non-metallic parts, special tools should be used when removing the O-ring. The bolts on the flange must be tightened symmetrically, gradually and evenly. â— The cleaning agent should be compatible with the rubber parts, plastic parts, metal parts and working medium (such as gas) in the ball valve. When the working medium is gas, the metal parts can be cleaned with gasoline (GB484-89). Non-metallic parts are cleaned with pure water or alcohol. â— Decomposed individual parts can be cleaned by dipping. Metal parts that have been left undecomposed by non-metallic parts can be scrubbed with a clean and fine cloth impregnated with a cleaning agent (to prevent the fibers from falling off and sticking to the parts). During cleaning, remove all grease, dirt, glue, dust, etc. adhering to the wall. â— Non-metallic parts should be taken out of the cleaning agent immediately after cleaning. Do not soak for a long time. â— After cleaning, the wall cleaning agent should be evaporated. (It can be rubbed with silk cloth without dipping agent), but it should not be left for a long time, otherwise it will rust and be polluted by dust. â— New parts should be cleaned before assembly. â— Lubricate with grease. Grease should be compatible with ball valve metal materials, rubber parts, plastic parts and working media. When the working medium is gas, for example, special 221 grease can be used. Apply a thin layer of grease to the surface of the seal mounting groove, apply a thin layer of grease to the rubber seal, apply a thin layer of grease to the sealing surface and friction surface of the valve stem. Debris, fiber, grease (except for the use of specified) dust and other impurities, foreign matter, etc., contaminate, adhere or stay on the surface of the part or enter the cavity
1) The packing should be re-locked. If there is micro-leakage at the packing, the stem nut must be locked.
Note: Do not lock too tightly, usually lock 1/4 turn to 1 turn, the leak will stop.
2) Replace the valve seat and seal A), disassemble the valve in the half-open position, flush and remove dangerous substances that may exist inside and outside the valve.
Close the ball valve, remove the connecting bolts and nuts on the flanges on both sides, and then completely remove the valve from the line.
Disassemble the drive unit-actuator, connecting bracket, lock washer, stem nut, butterfly shrapnel, Grennan, wear plate and stem packing.
Remove the body cover connecting bolts and nuts, separate the bonnet from the valve body, and remove the bonnet gasket.
Verify that the ball is in the "off" position, which allows it to be easily removed from the valve body and then removed from the seat.
Push the valve stem down from the hole in the valve body until it is completely removed, then remove the O-ring and the stem under the valve.
Note: Be careful to avoid scratching the stem surface and the body packing seal.
B), reassembly and cleaning, inspection and removal of parts, it is strongly recommended to replace the seals such as seat and bonnet gasket with spare parts.
Assemble in the reverse order of disassembly.
Use the specified torque to cross-lock the flange connection bolts.
Lock the stem nut with the specified torque.
After installing the actuator, input the corresponding signal to rotate the spool through the rotary valve stem to open the valve to the open and closed positions.
If possible, perform a pressure seal test and performance test on the valve in accordance with relevant standards before returning the pipe.
