The function and working principle of pneumatic valve ( Figure) _ pneumatic components factory valve industry

The role of the pneumatic pneumatic valve pneumatic valve: pneumatic valve used to need to quickly truncate or fully open pipe and transceiver pneumatic device fitted, it has compact structure, fast operation, small flow resistance, good sealing performance, etc. The structure of the pneumatic valve, pneumatic valve is mainly composed of valve body, valve stem and valve pneumatic, seat, actuators, etc. As shown in the figure below: (1) left the body flange connection (2) (3) pneumatic screw joint core (4) (5) seal I 6 washers 7) seal II nozzle pet-name ruby stem attending right body ⑾ handles. The working principle of pneumatic valve, pneumatic valve opening and closing for a pneumatic body, when start the actuators, through the transmission device drives the valve rod rotation, the axis of the stem drive pneumatic body around the stem rotate 90 °. When all the inlet and outlet pipe pneumatic surface rendering, pneumatic valve closed, the fluid be truncated; When the aerodynamic body channels and pipe diameter on the timing, pneumatic valve is fully open, fluid conduction; Full equality of the valve body cavity for medium resistance is very small, straight flow channel. Timely gathered in seating surfaces or pneumatic valve operation is conducive to eliminate impurities on the surface of the valve pneumatic, each operation of pneumatic valve can make the seat ring 15 ° rotation, and uniform distribution of inlay in the seat wear. Pneumatic valve use note: 1, online use pneumatic valve must be 1 times a year maintenance, cleaning and after pigging operation and strengthen the valve cavity drainage in winter. 2, pneumatic valve should activities at least once a month, in order to avoid valve pneumatic jammed. 3, pneumatic valve does not reach the designated position not to open and close the valve cavity drainage. 4, pneumatic valve can only be fully open or close, not for throttling. : electric top mounted fixed working principle of the pneumatic valve ( Dynamic figure) Fixed working principle of the pneumatic valve American standard Dynamic figure)
