Embodiment Construction

[0032] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] In order to achieve the purpose of the present invention, as figure 1 As shown, in some embodiments of the sealing inspection device for flange assembly of the present invention, it includes: a cavity 3, which has an opening 31, and the flange assembly 2 passes through the flange assembly 2 during inspection. The hole is fixedly arranged on the opening 31 in other ways such as self-positioning or clamping, and the cavity 3 is also connected to an air source (not shown); the driving unit 4 is arranged at the opening 31, and the driving unit 4 passes through it during inspection. The power output shaft presses the flange assembly 2 from the outside of the cavity 3; the pressure gauge 5 is installed in the cavity 3 and detects the pressure in the cavity 3.

[0034] Such as figure 1 As shown, in order to form a more stable installation s...

Abstract

The invention discloses a sealing performance inspecting device for a flange assembly. The device comprises a cavity with an opening, a driving unit arranged on the opening, and a pressure gage installed on the cavity and used for detecting the pressure in the cavity, wherein the flange assembly is fixedly arranged on the opening when being inspected, and the cavity is further connected with a gas source; the flange assembly is pressed by the driving unit from the outer side of the cavity through a power output shaft of the driving unit in the inspecting process. According to the sealing performance inspecting device for the flange assembly, the sealing performance of the flange assembly is detected according to the airtightness principle; compared with an underwater inspection mode in the prior art, outside interference factors can be effectively isolated while implementation is facilitated, and therefore the inspection accuracy of the flange assembly can be effectively improved.

Description

technical field [0001] The invention relates to a sealing test device, in particular to a sealing test device for a flange assembly. Background technique [0002] With the continuous advancement of science and technology, people have higher and higher airtight requirements for some machines and equipment, and flange components are one of them. When the flange and the end cover are assembled into a flange assembly, whether there is air leakage at the installation position of the bolt connecting the flange and the end cover and the threaded hole on the end cover, and whether there is air leakage at the contact surface between the flange and the end cover are the inspections of the flange assembly product. Bad key factor. Once the flange assembly leaks, the whole machine installed with the flange assembly will have quality problems such as damage due to air leakage, which will cause the product to face consequences such as repairs and market recalls. [0003] For this reason,...
