Embodiment 1

[0037] An airtightness detection joint provided in this embodiment has a structure as shown in the figure.

[0038] Wherein the same components are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "bottom" and "top "Face", "inner" and "outer" refer to directions toward or away from, respectively, the geometric center of a particular component.

[0039] The leak-tight test connector, including,

[0040] Inflatable pipe 212, one end is used to insert into the seam 11 of the bellows, and the other end is connected to the blower;

[0041] Inflatable ports are distributed on the tube body where the inflatable tube 212 is inserted into the mouth 11;

[0042] The check valve 214 is located on the inflation port, allowing airflow to enter the bellows from the inflation pipe 212, and preventing the airflow from enteri...

Embodiment 2

[0053] An air tightness detection joint, the difference from Embodiment 1 is that the guide surface 2124 extends around and forms a retaining edge 2125 that blocks the non-return valve 214 .

Embodiment 3

[0055] An airtightness detection platform, comprising the airtightness detection joint of embodiment 1 or embodiment 2.

Abstract

The invention discloses an air tightness detection system, which relates to the technical field of bellows air tightness detection. The airtightness detection system includes an airtightness detection platform, an inflation module, a pressure detection module, a processor, a comparison module, and a terminal. In this solution, the bellows is filled with gas to form a certain pressure in the bellows, and then the pressure change in the bellows is measured by the sensor after the inflation is stopped to determine whether the bellows is leaking. And a change value ΔP is preset by the system, so that products exceeding ΔP are automatically judged as unqualified products. The bellows will not be polluted during the detection process, and the detection process has a higher degree of automation, which saves manpower input and speeds up the detection speed.

Description

technical field [0001] The invention relates to the field of bellows airtightness detection, in particular to an airtightness detection system. Background technique [0002] Bellows are commonly used elastic elements. Such as figure 1 As shown, the entire pipe body is composed of several crests 12 connected end to end, and notches 11 are respectively provided at both ends of the corrugated pipe 1 in the length direction. The seam 11 is used to connect with other components. [0003] The corrugated pipe 1 is usually used for the transportation of fluids. Therefore, after the corrugated pipe 1 is actually produced, it is necessary to perform an airtightness test on the corrugated pipe 1 . Qualified products that pass the test can be sold and used. [0004] The airtightness test of bellows often adopts "color difference method". [0005] The specific steps of the color difference method are as follows: [0006] First, the staff seals one end of the corrugated pipe to be t...
