A detailed description of the powder for the pneumatic valve system

Pneumatic valve consists of valve stem, shaft sleeve, fastening pin, on board, the valve stem, valve seat, o-rings, bushings, valve, seal, under the lower cover, and the top of the stem connection on pneumatic device, the outer surface of the body on product along the outer circumference of a circle with embedded grooves, seats for the elastic sealing seat of the product. This product can adjust seating pressure, the outer surface of the valve body along the outer circumference of a circle with embedded grooves, the seat inlaid on the valve body gaps, the valve body, valve seat and plate work together to achieve zero leakage, sealed performance is good, at the same time in the process of plate rotation, reduce friction and open-close torque, greatly improve the wear of the valve, sealing performance. Pneumatic valve powder system, and need to take into account other factors, such as: can't keep the material from the above on the car directly rushed to the valve on the valve plate ( The impact can also make the valve cannot be closed tightly) And the static pressure of the material must be no more than the design of the pneumatic valve bearing pressure, and so on. The difference between the control valves and common manual valve is, can't take it as an isolated elements, and must take it as an integral part of the whole control system, control valve to use many of the problems, selection and configuration is not problem, but because of lack of awareness of control valve in control valve user fails to cooperate with control system debugging, good. As long as the key to realize problem, correct selection, the valve and control valve in the system debugging phase debugging good, can greatly reduce the failure rate, long-term stability of the automatic control system.
