Abstract

The invention discloses a testing device and a testing method for an embedded-mounted check valve. The testing device comprises a high-pressure air cylinder, a decompression valve, a filter, a normally closed electromagnetic valve, a check valve mounting seat and a ball valve. The testing device further comprises an electric control cabinet and a pressure sensor. The pressure sensor is connected with the check valve mounting seat. The electric control cabinet is connected with the pressure sensor and the normally closed electromagnetic valve. The testing device can prevent various adverse effects such as power loss and pressure loss caused by check valve leakage in the field in which the check valve is used.

Description

technical field [0001] The application belongs to the technical field of one-way valve testing, and in particular relates to an embedded installation type one-way valve testing device and testing method. Background technique [0002] A check valve is a directional control valve in which airflow can only flow in one direction and cannot flow in the opposite direction. Its working principle is the same as that of a hydraulic check valve. The check valve is used in occasions where the air flow is not allowed to flow in reverse. For example, when the air compressor inflates the air tank, a check valve is installed between the air compressor and the air tank. When the air compressor stops working, it can prevent the air tank from The compressed air returns to the air compressor. One-way valves are often combined with throttle valves and sequence valves to form one-way throttle valves and one-way sequence valves. [0003] The traditional embedded check valve leak detection work...
