track cock pneumatic valve USES: orbit cock pneumatic valve (
Nicknamed the general pneumatic valve)
Applicable to the nominal pressure CLASS -
LBS, working temperature -
-
℃ in the petroleum, chemical, pharmaceutical, chemical fertilizer, power industry, such as the pipeline under various working conditions, cut off or connect pipe medium.
track cock main structure characteristics of pneumatic valve: 1) pneumatic valves in the process of switch, pneumatic valve sealing surface and sliding vane seal face without any contact, therefore, no friction, wear, long service life of pneumatic valve, switch moment;
2. Pneumatic valve in the maintenance, do not need pneumatic valve from the line will be removed, just put the bottom cover pneumatic valve apart, changing a pair of sliding vane, maintenance is very convenient.
(3) pneumatic valve body and cock for full size, when medium by a pneumatic valve flow resistance, and can pass the ball to the pipeline cleaning, overcomes the drawback of reducing pneumatic valves;
(4) full size general pneumatic valve pneumatic valve body cavity with hard chromium plating, seal hard and glossy area;
(5) on the elastic sliding vane seal using fluorine rubber, and molding in the slide groove surface.
With fire prevention function of the metal to metal seal as the backing of elastic seal;
6 pneumatic valves with automatic discharge device (
Optional)
After the pneumatic valve is fully closed, to prevent the abnormal pressure pneumatic valve cavity and to examine the effects of pneumatic valves;
7) pneumatic valve switch position indicator and synchronization, can accurately display gear drive full size general pneumatic valve switch state.
orbit cock pneumatic valve working principle: and when the pneumatic valve fully open state, the plug of the channel and pneumatic valve body alignment, can guarantee the ideal minimum pressure drop.
, when turning the handwheel, the plug will spark valve in the direction of rotation, and drive the pneumatic valve slice rotation degrees, when to turn the handwheel, the plug will press, pneumatic valve to open on both sides, pneumatic valve will be tightly on the pneumatic valve seat, to close the pneumatic valve.
and when the handwheel to reverse direction, first of all make plug upward movement, pneumatic valve in pneumatic seat from, continue to turn the handwheel, make the plug turns pneumatic valve plates, the plug of the channel in pneumatic valve body alignment, make the state of the pneumatic valve is fully open.
and the advantage of the pneumatic valve is in the process of the pneumatic valve in the open, pneumatic valve and pneumatic seat in the off state, the process of switch is zero friction, won't make the sealing surface wear, sealing with soft sealing at the same time, make the seal when closed to zero leakage.
