Describe
The plunger stop valve is composed of valve body, valve cover, valve stem, plunger, guide, seal ring, hand wheel and other parts (pictured). When the hand wheel rotates, the plunger is driven to reciprocate up and down in the guide sleeve by the valve stem, so that the inclined end surface of the plunger end and the tapered surface of the valve seat complete the opening and closing function of the valve. In the plunger stop valve, an interference fit is adopted between the plunger and the seal ring. By adjusting the pre-tightening force of the middle flange bolt, the lateral force generated by the compression of the seal ring is sealed with the outer circumference of the plunger in the valve body, thereby ensuring the seal. The sealing of the valve eliminates internal leakage. Since the sealing ring adopts a non-toxic new sealing material with strong resilience and high wear resistance, the sealing is reliable and durable. Thereby increasing the service life of the plunger stop valve. The plunger shut-off valve combines the leak-free function of the plunger valve with the quick opening and closing of the shut-off valve, and becomes a new product with novel structure and wide application.
