Abstract

The invention is an explosion-proof angle seat valve, comprising: a valve body, a muffler, a front cover, a piston rod, a piston, an exhaust pressure regulating joint, a rear cover, a cylinder barrel, a return spring, a guide groove, a limit plate, a spring one, A damping shaft sleeve, an elastic part and a plug; the valve body is also provided with a water discharge damping mechanism. Compared with the prior art, the present invention adopts the hemispherical plug and the dislocation arc-shaped groove to cooperate, and solves the technical problem that the water pressure fluctuates violently when the piston is used to close the pressure plate and the water flow opening is closed in the prior art, causing the valve body to vibrate violently. . At the same time, the water discharge damping mechanism is arranged in the groove, which further prevents the problem of excessive water pressure when the plug closes the groove; and the damping bushing is set between the piston rod and the plug, which can greatly reduce the blocking of water flow. head shock.

Description

technical field [0001] The invention belongs to the technical field of valves, in particular to an explosion-proof angle seat valve. Background technique [0002] The angle seat valve is usually a valve that uses a pneumatic drive mechanism to adjust the fluid flow. In actual work, the angle seat valve needs to frequently control the on-off of the valve body. In the existing angle seat valve, the piston rod is used to drive the pressure plate to close the water inlet, while the pressure plate and the water inlet in the angle seat valve are usually designed to be parallel to each other, which will cause the water pressure to fluctuate violently at the moment when the water inlet is closed. The valve body vibrates violently. At the same time, when the piston rod drives the closed pressure plate to move, the impact force of the water flow on the pressure plate will drive the piston rod to shake. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to pr...
