Description

Plunger valve suitable for high pressure

Technical Field

The application relates to a plunger valve, in particular to an applicable high-pressure plunger valve.

Background

The plunger valve consists of valve body, valve cover, valve rod, plunger, hole frame, sealing ring, hand wheel and other parts. When the hand wheel rotates, the valve rod drives the plunger piston to reciprocate up and down in the middle of the hole frame to complete the opening and closing functions of the valve. The plunger and the sealing ring in the valve adopt interference fit, and the lateral force generated by the compression of the sealing ring is sealed with the hole surface in the valve body and the excircle of the plunger by adjusting the flange bolt in the gland, so that the sealing property of the valve is ensured, the internal and external leakage is avoided, the opening torque of the valve is small, and the valve can be opened and closed rapidly. Compared with a stop valve, the plunger valve has long service life and labor-saving operation.
