Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0025] An automatic PE tee joint 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 is determined inside the joint 5 .
[0026] The positioning seat 2 is a U-shaped block placed horizontally with an opening facing outwards. The height of ...

The invention discloses an automatic leakage detecting device for a PE (Poly Ethylene) tee joint and relates to the field of a test machine for sealing property. The automatic leakage detecting device for the PE tee joint comprises a base, wherein a positioning base for the tee joint, a branch pipe positioning bracket, a sealing property test mechanism and a pushing mechanism for the sealing property test mechanism are arranged on the base. The invention provides the automatic leakage detecting device which can be inserted into the interior of the PE tee joint, aims at the sealing at a welding joint and is capable of reducing the test cavity and increasing the sensitivity of a high pressure sensor, in order to solve the problems of the large-size tee joint that the plugging at the outlet is adopted, the interior cavity is large and the baroceptor is difficult to judge the micro-leakage.
Description
technical field [0001] The invention relates to the field of sealing performance testing machines, in particular to an automatic PE tee joint leak testing device. 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 sealing perfor...
