Problems solved by technology

The traditional valve core opening pressure detection device needs to screw the valve core into the valve core cavity, and then conduct the test. The whole process requires a screwing process, which is complicated to operate and low in efficiency, and cannot meet the needs of mass production and rapid detection.

Abstract

The invention relates to a batch valve core air-tightness test device, which is characterized in that the device comprises a press machine body (1), an upper die plate (2), a lower die plate (3), an exhaust plate (4) and a water tank (5); the upper die plate (2) is fixed on the upper working surface of the press machine body (1), the water tank is arranged on the lower working surface of the press machine body (1), the exhaust plate (4) is arranged above the water tank (5), a plurality of exhaust pipes (4.1) are evenly arranged on the exhaust plate (4), the exhaust pipes (4.1) are inserted below the surface of liquid in the water tank (5), a plane mirror (5.1) is arranged at the bottom of the water tank (5) and at least one observation surface of the water tank (5) is made of a transparent material. The batch valve core air-tightness test device has the advantages that the structure of the entire test bench is simple, the test device is easy to operate and the test efficiency is high.

Description

technical field [0001] The invention relates to a batch valve core air tightness test device, which is mainly used for detecting the opening pressure of the valve core at the production site of the valve core. Background technique [0002] Valve core manufacturers need to quickly and accurately measure the opening pressure of the valve core at the valve core production site or laboratory, and then judge whether the valve core is qualified. The traditional valve core opening pressure detection device needs to screw the valve core into the valve core cavity, and then perform the test. The whole process requires a screwing process, which is complicated to operate and low in efficiency, and cannot meet the needs of batch and rapid detection. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a batch valve core airtightness testing device with simple operation and high working efficiency. [0004] The objec...
