Flange piston valve structure and characteristics
Plunger valve is the valve body, valve cover, stem, plunger, hole frame, ring, hand wheel and other components (pictured). When the hand wheel is rotated, the plunger is driven by the valve rod to reciprocate up and down in the middle of the hole frame to complete the function of opening and closing the valve. In the valve plunger and the seal ring between the interference fit, by adjusting the gland flange bolts, the seal ring compression products generated by the lateral force and the valve body bore and plunger outer seal to ensure that the valve The sealing, to eliminate the internal leakage, while the valve opening moment is small, to achieve the rapid opening and closing of the valve. As the seal ring with resilient and wear-resistant non-toxic new sealing materials, with long-term high temperature, high pressure without losing flexibility, so the sealing performance reliable, durable.
