Problems solved by technology

[0002] In the nuclear power industry, most of the testing and research on the sealing performance of penetrations are electrical penetrations, as well as the introduction and analysis of sealing test methods, the acceptance specifications of penetrations, the standards for comparing the leakage rate of sealing tests, and the comparison of mechanical penetrations. Few, there are few test devices for testing the sealing performance of mechanical penetrations such as valve remote transmission mechanisms, which causes inconvenience to the acceptance of mechanical penetrations. Manufacturers cannot carry out tests on the sealing performance of mechanical penetrations, and it is difficult to test mechanical penetrations Improved sealing structure

Abstract

The invention provides an air tightness test device for a mechanical penetration piece, and the device comprises a sealing part which is internally provided with a sealing cavity, and the sealing part and the mechanical penetration piece form a relatively sealed environment after being connected; an air source system, communicated with the sealing cavity to exhaust or inflate the sealing cavity; a detection system, comprising a pressure transmitter and a temperature sensor which are arranged in the sealing cavity; a control computer, data collected by the detection system bieng transmitted to the control computer and displayed through the control computer, and the control computer can control starting of the detection system. The device can achieve the effects of facilitating the airtightness detection of the mechanical penetration piece and facilitating the acceptance inspection of the mechanical penetration piece.

Description

technical field [0001] The invention relates to an airtightness test device, in particular to an airtightness test device for a mechanical penetrating part. Background technique [0002] In the nuclear power industry, most of the testing and research on the sealing performance of penetrations is biased towards electrical penetrations, as well as the introduction and analysis of sealing test methods, the acceptance specifications of penetrations, the standards for comparing the leakage rate of sealing tests, and the comparison of mechanical penetrations. Few, there are few test devices for testing the sealing performance of mechanical penetrations such as valve remote transmission mechanisms, which causes inconvenience to the acceptance of mechanical penetrations. Manufacturers cannot conduct tests on the sealing performance of mechanical penetrations, and it is difficult to test The sealing structure is improved. Contents of the invention [0003] In view of the above-men...
