Plunger valve is composed of valve body, valve cover, valve stem, plunger, hole rack, sealing ring, hand wheel and other parts. When the hand wheel rotates, the valve opens and closes by driving the plunger up and down in the middle of the hole rack by the valve stem. The interference fit between the plunger and the sealing ring is adopted in the valve. By adjusting the flange bolt in the pressure cap, the lateral force produced by the compression of the sealing ring is sealed with the orifice in the valve body and the outer circle of the plunger, thus ensuring the sealing of the valve, eliminating the leakage inside and outside, and at the same time, the opening moment of the valve is small, so that the valve can be opened and closed quickly.
