An anti-vibration one-way valve disc protection device

Abstract

The invention discloses an anti-vibration one-way valve disc protection device. The invention includes a main valve body, the main valve body is provided with a water inlet opening to the left, and the right side of the water inlet is connected with a vertically penetrating The water outlet, the right wall of the water outlet is connected with a spring chamber, the upper and lower walls of the water inlet are connected with a symmetrical lever chamber, the right side of the lever chamber is connected with the left wall of the water outlet with a sliding chamber, The right wall of the water outlet is communicated with a hinged chamber that extends rightward and the right end extends downwards to communicate with the upper and lower walls of the spring chamber, and the lever chamber is provided with a lever mechanism that extends rightward into the hinged chamber. The right end wall of the water inlet is provided with an annular sealing surface. The present invention can make the opening speed of the one-way valve normal through the ratchet mechanism with friction force, and the closing speed can be slowly closed by the ratchet wheel and the friction block, thereby reducing Vibration and noise when the disc is closed.

Description

technical field [0001] The invention relates to the related field of hydraulic valves, in particular to an anti-vibration one-way valve flap protection device. Background technique [0002] The one-way valve is that the fluid can only flow along the water inlet, but the outlet medium cannot flow back, commonly known as a one-way valve. One-way valve is also called check valve or check valve. Used in hydraulic systems to prevent reverse flow of oil flow, or used in pneumatic systems to prevent reverse flow of compressed air. The medium pressure before and after the check valve is close to balance and "seesaw" each other. The valve disc often beats with the valve seat, and the valve disc made of some brittle materials such as cast iron and brass is broken, and when the one-way If the liquid flowing in the valve contains some garbage or particles and other substances, it is very easy to wear the valve disc. It is difficult for some existing one-way valve disc protection devi...

The medium pressure before and after the check valve is close to balance and "seesaw" each other. The valve disc often beats with the valve seat, and the valve disc made of some brittle materials such as cast iron and brass is broken, and when the one-way If the liquid flowing in the valve contains some garbage or particles and other substances, it is very easy to wear the valve clack

Some existing one-way valve disc protection devices are difficult to play the role of shock absorption, and the filtering effect on liquid is not good
