Flange plunger structure and characteristics of the pneumatic valve

plunger pneumatic valve by pneumatic valve, pneumatic valve cover, pneumatic valve stem, plunger, the hole planes, ring, hand wheel, etc. Parts ( As shown in figure) 。 When the hand wheel rotation, through the pneumatic valve rod drives the plunger in the middle of the hole rack up and down reciprocating movement to complete the pneumatic valves open and close function.
in the pneumatic valve USES the interference fit between plunger and seal ring, by adjusting the gland flange bolts, make the seal ring compression side force of the products and pneumatic valve hole in the side column and the Great Wall round seal, so as to ensure the sealing of the pneumatic valve, put an end to the inner leakage, pneumatic valve small open torque, at the same time to achieve rapid opening and closing of the pneumatic valve.
because of the sealing ring with strong resilience, high wear-resistant nontoxic new sealing material, have suffered long-term high temperature, high pressure without losing elasticity, so the sealing performance, reliable and durable.
