U41sm flange piston valve | structure and characteristics of flange angle piston valve

Plunger valve is composed of valve body, valve cover, valve rod, plunger, hole frame, sealing ring, hand wheel and other parts (as shown in the figure). When the hand wheel rotates, the valve rod drives the plunger to move up and down in the middle of the hole frame to complete the opening and closing function of the valve.

The interference fit is adopted between the plunger and the sealing ring in the valve. By adjusting the flange bolts in the gland, the lateral force generated by the compression of the sealing ring is sealed with the hole surface in the valve body and the outer circle of the plunger, so as to ensure the sealing of the valve, eliminate internal leakage, and at the same time, the valve opening torque is small, which can realize the rapid opening and closing of the valve.

As the sealing ring adopts non-toxic new sealing materials with strong resilience and high wear resistance, it can withstand long-term high temperature and high pressure without losing elasticity, so the sealing performance is reliable and durable.
