Anti-permeation equipment for gas thermometer

Abstract

Anti-permeation equipment for a gas thermometer is disclosed, and comprises an anti-permeation module, a base frame, a rivet assembly, and a diffusion device. The equipment employs an adaptive electronic check sealing device and a reaction buffer part. The control element of the equipment tests the permeation density by passing the gas flow from the inner layer pipe by means of a test piston and a rod-shaped pin member. The test piston is a series multi-stage electromagnetic switch inspection piston. The equipment effectively irons out a defect that equipment just can test strip-like anti-seepage components in a staged manner, and cannot be carry out the testing of strip-like anti-seepage components at a time.

Description

technical field [0001] The invention belongs to the technical field of gas thermometers, in particular to an anti-penetration device for gas thermometers. Background technique [0002] In the manufacture of gas thermometers, the use of components often requires the addition of corresponding common parts. Among these parts, the most important ones are anti-permeation parts. Such anti-permeation parts must be tested for the performance of the permeable gas. The key point is to raise the pressure on the surface of the anti-permeation component, but this method of testing the permeable gas is only a graded test of the strip-shaped anti-permeation component, and cannot be used for one-time testing. Contents of the invention [0003] The invention provides an anti-penetration device for a gas thermometer, which includes an anti-penetration component, a base frame, a riveted component and a splicer. The anti-penetration device for a gas thermometer uses an electronic inspection s...

[0002] In the production of gas thermometers, the use of components often requires the addition of corresponding common components. Among these components, the most important is the anti-permeation component. This type of anti-permeation component must be tested for the performance of the permeable gas. The key point is to increase the pressure on the surface of the impervious part, but this method of testing the permeable gas is only a graded inspection of the strip impermeable part, and cannot be used for one-time inspection.
