Manual with pilot pneumatic valve by pneumatic ball valve

overview
,
at present, most of the domestic by the pneumatic valve driven by the handwheel or electric devices. Driven by pneumatic valve opened or closed by hand wheel, action is slow, the intensity of labor is big, the low degree of automation, is not conducive to integrated control of pneumatic valves, and easy to cause safety accidents caused by incorrect operation. Using common electric actuator pneumatic valve, opening and closing as bloated, large energy consumption, high cost and the application on the road at the pipe of oil or chemical flammable fluid, inconvenient maintenance and accident hidden danger exists. So a new type with pilot pneumatic valve by pneumatic ball valve. The pneumatic valve can achieve the basic function of common stop pneumatic valve, with flexible operation energy saving, high accuracy, fast, no rust, easy installation, long service life and convenient maintenance, etc.

and pneumatic valve structure with pilot pneumatic valve by pneumatic ball valve has two types of manual control and electric control. Manual with pilot pneumatic valve by pneumatic ball valve ( Figure) By the pneumatic valve, pneumatic valve, pneumatic valve cover, guide sleeve, sealing ring and spring and the diversion pipe and other components. Pneumatic disc is straight cylindrical, pneumatic valve at the bottom of the bottom hole, lower pneumatic valve body is equipped with drainage hole, the hole with seal nut. Pneumatic disc bottom hole diameter less than the diameter of nozzle, pneumatic disc upper pressure ring.
with pilot pneumatic ball valve by pneumatic valve handwheel, pneumatic valve rod and the lifting nut, change the guide block and the guide groove to guide sleeve, change the disk type pneumatic disc to kind of bowl shape pneumatic disc, and in the open air disc at the bottom of the hole, will build the original pneumatic valve, pneumatic valve stem hole to flow guide hole because of the increased pressure ring, sealing ring, and change the pneumatic disc to kind of pot body, make the flow on the divided into cavity, external cavity, the cavity, and the outside of the cavity with external cavity has a diversion pipe and stainless steel manual pneumatic valve, ball in the center of the plate and pneumatic disc bottom added a spring, pneumatic disc upper adding pressure tight seal ring, external cavity walls opened a plug-hole. For electric control by the pneumatic valve, just put the pilot control of the pneumatic valve with manual ball ~ V dc motor driver.
