Abstract

The invention discloses a PE welding pipe leakage detection device, which relates to the technical field of pipe detection devices. The PE welding pipe leakage detection device comprises a main body and two lifting bodies, wherein the main body is column-shaped; the outer side wall of the main body is provided with two first sealing ring receiving grooves; each first sealing ring receiving grooveis internally provided with a first inflation sealing ring for fitting and sealing the inner wall of a four-way joint main pipe; the outer side wall of the main body is provided with a column-shaped sliding hole in a radially penetrating mode; the two lifting bodies have consistent structures and are both arranged in the sliding hole in a back symmetrical mode. In order to solve the problems thatthe existing PE welding pipe leakage detection testing method damages a pipe easily, misjudgment is caused easily, and the operation is cumbersome, the PE welding pipe leakage detection device which does not damage the pipe and has an accurate result and convenient operation is put forward.

Description

technical field [0001] The invention relates to the technical field of pipe fitting detection equipment, in particular to a leak detection device for PE welded pipe fittings. Background technique [0002] The PE welded pipe fittings here mainly refer to PE welded four-way pipe fittings. PE welded four-way pipe fittings are cross-shaped pipe fittings formed by welding a main pipe and two branch pipes. Mainly used for media diversion. Since the main pipe and the branch pipe are welded, due to factors such as welding temperature and unevenness of the butt joint, there may be leakage points at the weld. Therefore, PE welded pipe fittings need to undergo a leak test before leaving the factory. [0003] The conventional leak detection test method is to seal each nozzle of PE welded pipe fittings with a sealing cap, fill the inside of the pipe fitting with high-pressure gas, then immerse the entire pipe fitting in water, and judge whether there is leakage at the weld by observing ...
