Problems solved by technology

In the existing angle seat valve, the piston rod is used to drive the pressure plate to close the water inlet, and 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 the water inlet is closed, resulting in The valve body vibrates violently

Abstract

The anti-explosion angle seat valve comprises a valve body, a silencer, a front cover, a piston rod, a piston, an exhaust pressure regulating connector, a rear cover, a cylinder barrel, a reset spring, a guide groove, a limiting plate, a first spring, a damping shaft sleeve, an elastic component and a plug. A water drainage damping mechanism is further arranged in the valve body. Compared with the prior art, the hemispherical plug is matched with the staggered arc-shaped groove, and the technical problem that in the prior art, when a piston closing pressing plate and a water flow opening are closed, water pressure fluctuates violently, and consequently a valve body vibrates violently is solved. Meanwhile, due to the fact that the drainage damping mechanism is arranged in the groove, the problem that the water pressure is too large when the groove is closed by the plug is further solved; and the damping shaft sleeve is arranged between the piston rod and the plug, so that the impact of water flow on the plug can be greatly reduced.

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] Angle seat valves are usually valves that use a pneumatic drive mechanism to adjust fluid flow. In actual work, angle seat valves need 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, and 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 the water inlet is closed, resulting in 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. Contents of the invention [0003] The object of the present invention is to provide ...
