Manual with pilot pneumatic ball valve by pneumatic valve outline 2)

Overview



at present, as of the handwheel or pneumatic valve electric actuator driven most. Wheel drive pneumatic valve open or closed, slow, labor intensity, low degree of automation, is not conducive to integrated control pneumatic valve, could easily lead to the mistake caused by the accident. Used to open and close the pneumatic valve, big body, energy consumption, high cost of oil or general electric equipment of the explosive chemical fluid pipe, maintenance and use of accident of inconvenience. Thus established with the forerunner for a new type of pneumatic valve. The pneumatic valve can achieve common stop pneumatic valve has a flexible operation, energy saving, high precision, fast action, does not rust, easy installation, long service life, convenient maintenance, and other functions.

and pneumatic valve structure pilot pneumatic valve with manual control of pneumatic valve and electric control of two types. Manual pneumatic valve pilot pneumatic valve by pneumatic valve, pneumatic valve, pneumatic valve cover, guide sleeve, seal, spring and parts water diversion pipe ( Figure) 。 And cylindrical straight pneumatic valve, the bottom hole at the bottom of the pneumatic valve, drain holes and private parts, sealing nut mounting holes. Bottom hole diameter than the pneumatic valve guide tube, the upper portion of the disc ring less pressure.
with pilot pneumatic valve pneumatic valve without a handle, filed a pneumatic valve rod and the nut, the slider and the guide groove guide sleeve, into the bowl dish of pneumatic valve disc, and in open hole at the bottom of the pneumatic valve, pneumatic valve stem hole including the diversion tunnel, due to the increased pressure ring, sealing ring, change the disc type bowl, let flow into the cavity, the cavity external cavity, the cavity chamber and external cavity has a diversion pipe and stainless steel combined with manual cover cricket pneumatic valve and install the late spring center, additional compression pneumatic valve pressure sealing ring, the top of the wall outside the cavity is open drain. For electric regulating pneumatic valve, only the pilot manual? V dc motor can be controlled pneumatic valve.
