Pneumatic valve

the pneumatic valve is a kind of pneumatic valve using compressed air to drive the valve device, pneumatic valve with clear specifications, category, work pressure, so want to buy we will strictly in accordance with the parameters to the choose and buy. Working principle of the

pneumatic valve power comes from compressed air, main part, adjusting bolt, execute, enclosure structure, flight from shaft, cylinder block, cylinder, piston, connecting rod, cardan shaft. Pneumatic control valve is made up of actuators and regulating mechanism. Is a thrust part of the regulating valve actuator, it according to the size of the control signal pressure to produce the corresponding thrust, promote regulating mechanism. The body is the adjustment of the pneumatic control valve components, it is directly contact with control agent, regulating the flow of the fluid. Common type

1. Pneumatic
2 v-type regulating ball valve. Pneumatic type O cut the ball valve
3. Torque type cylinder valves
4. Electromagnetic diaphragm valve moving picture
5. Use pneumatic diaphragm valve straight program

1. The open-close direction of pneumatic valve operation, all should be clockwise to shut down.
2。 As the pneumatic valve in the pipeline, is often of artificial opening and closing, opening and closing of revolution shoulds not be too much, is the large diameter valves also should be within 200-600 RPM.
3。 In order to facilitate a person's opening and closing operation, under the plumber pressure conditions, big open-close torque appropriate for n - 240 m。
4。 Pneumatic valve opening and closing operation side should be square tenon, standard and size, and face to the ground, so that people can be directly from the ground. Valves shall not apply to the underground pipe network with roulette.
5。 Pneumatic valve opening and closing degree of display panel
1) pneumatic valve opening and closing degree of calibration, shall be cast on or after the transformation direction of gearbox cover plate shell, face to the ground without exception, the scale line brush on phosphor powder, as a prominent;
(2) the material of dial needle in case management better available stainless steel plate, or paint for steel plate, do not use the aluminum skin production;
3. Dial needle striking, fixation, once the open-close adjustment accurately, the rivet lock.
6。 If the pneumatic valve buried deep, operating mechanism and display plate distance from the ground 1 or more. 5 m, should be equipped with facilities of extension rod, and fixed firmly in mind, so that people from the face of the earth observation and operation. That is to say, the valve opening and closing operation in pipe network, unfavorable under operation.
