Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0024] A three-way automatic leak detection device, such as Figure 1 to Figure 3 As shown, it includes an L-shaped base 1 as a whole. The base 1 is provided with a positioning seat 2 for a tee joint 5, a branch pipe positioning bracket 9, a sealing performance testing mechanism 3, and a sealing performance testing mechanism. Agency 3 pushes agency 4. The positioning seat 2 is used for placing and positioning the tee joint 5, the sealing performance testing mechanism 3 is used for extending into the inner side of the tee joint 5 for sealing and testing the tightness, and the pushing mechanism 4 is used for sending the sealing performance testing mechanism 3 to the tee joint The position of the joint 5 is determined internally.
[0025] The positioning seat 2 is a U-shaped block placed horizontally with an opening facing outwards. The height o...

The present invention discloses an automatic leakage detection device for a tee joint. The device comprises a base. The base is provided with a positioning seat for the tee joint, a branch outlet pipe positioning bracket, a sealing performance test mechanism, and a pushing mechanism for the sealing performance test mechanism. According to the technical scheme of the invention, the problem in the prior art that due to the facts that the outlet of a large-size tee joint is blocked and the internal cavity of the large-size tee joint is relatively large, the micro leakage is not easily found out by means of a gas pressure sensor can be solved. The above device can extend into the interior of a PE tee joint to detect the leakage at the sealing part of a weld. By means of the automatic leakage detection device, a test cavity is reduced and the sensitivity of the gas pressure sensor is improved.
Description
technical field [0001] The invention relates to the field of sealing performance testing machines, in particular to an automatic leak testing device for a PE tee joint weld. Background technique [0002] Tee joints are used as pipe fittings and pipe connectors, and are generally used at the branch pipes of the main pipeline for medium diversion. The branch pipes of industrial PE (polyethylene) tee joints are usually welded by pipe fittings. Leakage may occur at the welded joints due to reasons such as welding temperature and uneven butt joints, and the leakage of the tee joints is concentrated at the welded joints. . However, as an important pipeline connection of the gas pipeline network, there will be a greater safety hazard if there is leakage. Therefore, it is required to conduct a sealing performance test with compressed gas as the medium before use. [0003] At present, the water bubble method and the air pressure sensor monitoring method are usually used for the sea...
