AI Technical Summary

Technical Problem

In traditional solenoid valve assembly sealing detection methods, high testing pressure may cause damage to the sealing material or structure of the component internally, affecting the accuracy and reliability of the test results, and may lead to missed inspection and increased production costs.

Method used

A solenoid valve assembly detection device is designed to inject carbon dioxide gas into the detection chamber through the gas injection chamber, gradually increase the internal pressure, and use the elastic structure of the pressure relief chamber and the automatic exhaust hole to adjust the pressure to avoid damage to the assembly from high pressure, and evaluate the sealing of the assembly by real-time monitoring of gas concentration and pressure.

Benefits of technology

It effectively avoids damage to the solenoid valve assembly by high pressure, ensures the accuracy and reliability of test results, reduces missed inspection and production costs, and improves detection efficiency and equipment versatility.

Abstract

The invention discloses an electromagnetic valve assembly detection device which comprises a supporting table, an operation table, a detection bin, an assembly part, a pressure relief bin, a gas injection bin and a gas injection assembly. The detection bin is fixedly connected to the top of the operation table, and the assembly part is installed at the bottom of the inner side of the detection bin and used for clamping a to-be-detected electromagnetic valve; one end of the pressure relief bin and one end of the gas injection bin penetrate through the two sides of the detection bin correspondingly and are connected with an outlet and an inlet of the electromagnetic valve correspondingly, the gas injection assembly is installed on one side of the top of the operation table, and the end of the gas injection assembly is connected with the other end of the gas injection bin. Therefore, when the pressure reaches a preset value, the gas leakage hole can automatically discharge excessive gas, so that the pressure is adjusted, the electromagnetic valve assembly is prevented from being damaged by high pressure, a sensor in the detection bin records gas concentration changes in real time, the sealing performance of the electromagnetic valve assembly is detected, and if abnormal gas concentration changes are found, it is indicated that leakage exists in the assembly; and evaluating the sealing performance of the electromagnetic valve assembly according to the gas concentration and pressure data.
