Abstract

The invention discloses a simple axial inflation sealing performance testing device and method and a processing method. The simple axial inflation sealing performance testing device comprises a main shell and a rotating body. An accommodating cavity is formed in the main shell, and at least one test channel communicated with the accommodating cavity is formed in the main shell; the rotating body is arranged in the accommodating cavity, and the rotating body and the main shell can rotate relatively; an axial air inlet / outlet channel and at least one air path channel are arranged in the rotating body; one end of the intake / exhaust channel is provided with an intake / exhaust port, and the other end is closed; one end of the air channel is provided with a first connector communicated with the air inlet / outlet channel, and the other end of the air channel is provided with a second connector communicated with the accommodating chamber; a sealing structure is further included. The testing device disclosed by the invention is used for testing the air tightness of a non-sealing product or a sealing product, and has the characteristics of simple structure, convenience in processing and assembling and good testing precision.

Description

technical field [0001] The invention relates to an airtightness testing structure, in particular to a simple axially inflatable airtightness testing device, method and processing method. Background technique [0002] Due to the miniaturization of electronic components, such as crystal oscillators, chips, etc., the volume of the product is getting smaller and smaller, and a smaller test volume is required to improve the sensitivity and accuracy of the test and achieve the ideal test effect. In the prior art, the Chinese invention patent with the application number 201910334704.5 discloses a differential pressure air tightness tester and a test method. The differential pressure air tightness tester includes an air source interface, an inflation / inhalation valve, and an air release valve , the first pressure maintaining valve, the second pressure maintaining valve, the differential pressure sensor, the first pressure dividing valve, the second pressure dividing valve, the inter...
