As pneumatic valve opening and closing is plug pneumatic valve, sealing above is flat or cone, the pneumatic pneumatic valve seat valve to open/close the center line of a straight line, mainly used for cutting medium in the pipeline, simple structure, easy to install, easy to operate, channel flow, flow resistance small, simple structure and so on.
plastic as pneumatic valve structure principle
the pneumatic valve is closed ( Pneumatic disc) Move along the center line of the pneumatic valve seat of pneumatic valve. According to the mobile form of pneumatic valve, pneumatic valve seat with pneumatic disc change in his itinerary directly proportional relationship. Because this pneumatic valve open or close the pneumatic valve stem travel relatively short, and very reliable cutting function, and due to the change of pneumatic seat his trip proportional relationship with the pneumatic valve, is very suitable for the traffic regulation. Therefore, this type of pneumatic valves are well suited for use as cut off or adjust and throttling.
1, the opening and closing without friction. This function completely solve the traditional pneumatic valves for sealing surface friction each other and affect the sealing problem.
2, the structure of the jacket type. For pneumatic valve can be directly mounted on the pipeline online inspection and maintenance, can effectively reduce the parking device, reduce the cost.
3, single pneumatic valve seat design. Eliminates the pneumatic valve lumen medium because of abnormal pressure and problems affecting the safety of use.
4, low torque design. Special structure design of the pneumatic valve stem, only with a small hand can easily open/close the pneumatic valve.
5, wedge seal structure. Pneumatic valve by pneumatic valve stem provides mechanical force, wedge pressure to the pneumatic seat and seal, pneumatic valve's sealing is not affected by changes in the pipeline pressure difference, under various conditions sealed performance has a reliable guarantee.
6, the structure of the sealing surface of self-cleaning. When body tilting away from the pneumatic valve seat, fluid in the pipeline along the sealing surface into 360 ° evenly through the body, not only eliminates the high velocity of pneumatic seat local scour, also washed away by the accumulated on the surface of the sealing material, achieve the goal of the clean.
7, pneumatic valve diameter (below the opening and closing by pneumatic valve stem for all plastic production, more than DN65 for plastic clad steel material, flow components for all plastic anti-corrosion performance is high.
8, for corrosion resistant plastic material ( FRPP材质、CPVC、UPVC、PPH, PVDF)
plastic by the working principle of the pneumatic valve
A, open the process
1 in the closed position, pneumatic valve body subjected to mechanical pressure pneumatic valve stem, press on the pneumatic valve seat.
2 when counterclockwise rotation handwheel, pneumatic valve stem is reverse movement, the Angle at the bottom of the plane body release pneumatic seat.
3 pneumatic valve stem continue to ascend, and pneumatic valve rod guide pin of interaction in the spiral groove, the body began to rotate without some friction.
until 4 to full open position, pneumatic valve stem ascending to the limit position, body rotation to the full open position.
B, closing process
1 is closed, the handwheel clockwise, pneumatic valve rod began to drop and begin to spin from the body of pneumatic seat.
2 continue to rotate handwheel, pneumatic valve stem is embedded in the spiral groove on the role of the guide pin, make pneumatic valve stem and disc rotate 90 ° at the same time.
3 is almost closing lock body has been without contact with the pneumatic valve seat rotated 90 °.
4 wheel rotation of the last few laps, pneumatic valve stem mechanically wedge Angle at the bottom of the plane to the oppression, make its strong pressure on the pneumatic valve seat, completely sealed.
