A pneumatic one-way damping valve

Abstract

The invention discloses an air-controlled one-way damping valve, comprising: a valve body, a control port joint, an inlet joint assembly, a spring seat I, a spring I, a valve assembly, a bushing, a push rod, a deflation valve and a screw plug. The valve body is provided with valve body interface I, valve body interface II, valve body interface III and valve body interface IV, and valve body interface I and valve body interface IV are connected, valve body interface II, valve body interface III and valve body The interface IV communicates with each other. The control port joint and the inlet joint assembly are respectively threaded with the valve body interface I and the valve body interface II. The inlet joint assembly includes the inlet joint, the damping cone valve assembly, the spring III and the spring seat, and the inlet joint Both ends are processed with external threads. The present invention can be applied to high-pressure work of 7-15 MPa. The air-controlled one-way damping valve adopts a structure of multiple damping plates at the inlet joint. When the outlet pressure is higher than the required pressure, the increase Large gas flow resistance prevents damage to the pipeline caused by excessive air flow.

Description

technical field [0001] The invention relates to the technical field of damping valves, in particular to an air-controlled one-way damping valve. Background technique [0002] Usually, the pressure gas in the range of 10-100MPa is called high-pressure gas; the operating environment of high-pressure gas is harsh, and high-pressure gas circuit valves require high precision and high reliability; one-way valves, also known as one-way valves or check valves , is a directional control valve in which fluid can only flow in one direction and cannot flow in the opposite direction; check valves are widely used in various pneumatic and hydraulic control systems, but the existing pneumatic check valves are usually simple in structure and only suitable for low pressure In the air circuit, the air flow rate is too fast to easily cause damage to the pipeline, and the installation is relatively cumbersome. The existing air-controlled one-way damping valve cannot meet the needs of actual use,...

[0002] Usually, the pressure gas in the range of 10-100MPa is called high-pressure gas; the operating environment of high-pressure gas is harsh, and high-pressure gas circuit valves require high precision and high reliability; one-way valves, also known as one-way valves or check valves , is a directional control valve in which fluid can only flow in one direction and cannot flow in the opposite direction; check valves are widely used in various pneumatic and hydraulic control systems, but the existing pneumatic check valves are usually simple in structure and only suitable for low pressure In the air circuit, the air flow rate is too fast to easily cause damage to the pipeline, and the installation is relatively cumbersome. The existing air-controlled one-way damping valve cannot meet the needs of actual use, so there is an urgent need for improved technology on the market to solve the above problems. question
