The plunger valve by valve body, valve cover, valve stem, plunger, the hole planes, ring, hand wheel, etc. Parts ( As shown in figure) 。 When the hand wheel rotation, through the valve rod drives the plunger in the middle of the hole rack up and down reciprocating movement to complete the valve door open and close function. In the valve door 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 the great circle hole surface in the valve body and column seal, so as to ensure the tightness of the valve gate, to eliminate the inner leakage, the valve door open torque is small, can realize the valve rapid opening and closing of the door. Due to seal ring with strong resilience, high wear resistance of nontoxic new sealing material, have suffered long-term high temperature, high pressure without losing elasticity, so the sealing performance, reliable and durable. Widely used in urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food, beverage and other industries.
