Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0026] A kind of automatic sealing performance testing equipment of fusion tee joint, such as figure 1 , figure 2 As shown, it includes a plane base 1, and the base 1 is provided with a positioning mechanism 2 of a tee joint 5, a sealing performance testing mechanism 3, and a pushing mechanism 4 of the sealing performance testing mechanism 3. The positioning mechanism 2 is used for placing and positioning the tee joint 5, the sealing performance testing mechanism 3 is used for extending into 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 5 Determine the position internally.
[0027] The positioning mechanism 2 is a cylinder 201 placed horizontally, the inner diameter of the cylinder 201 matches the outer diameter of the main p...

The invention discloses an automatic sealing performance testing device for a welded tee joint and belongs to the sealing performance testing machine field. The automatic sealing performance testing device comprises a base; and a positioning mechanism for the welded tee joint, a sealing performance testing mechanism and a push mechanism of the sealing performance testing mechanism are arranged on the base. With the automatic sealing performance testing device of the invention adopted, the problem of difficulty in judging trace leak by a pressure sensor which is caused by a large inner cavity which is brought by a situation that a large-sized tee joint is plugged at the outlets of the tee joint can be solved. The automatic sealing performance testing device can extent into the tee joint, so that the size of a testing cavity is decreased, and the sensitivity of the pressure sensor can be improved.
Description
technical field [0001] The invention relates to the field of sealing performance testing machines, in particular to an automatic sealing performance testing equipment for welding three-way joints. 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 u...
