Air tightness detection equipment for polyethylene pipe

Abstract

The utility model relates to the technical field of air tightness detection, in particular to polyethylene pipe air tightness detection equipment which comprises an observation box and a detection assembly, the detection assembly comprises a water supply mechanism, a supporting plate, a clamping mechanism, a supporting frame, a conveyor, a portal frame and a first air cylinder, and the observation box is used for observing the air tightness of a pipe and can store water; when the device is used, pipes are conveyed to the supporting plate through the conveyor, after enough pipes are conveyed to the supporting plate, the conveyor stops running, the clamping mechanism clamps the two ends of each pipe, then the first air cylinder controls the supporting plate to descend to enter the inner side of the observation box, and the portal frame is used for installing the first air cylinder; after the supporting plate enters the observation box, the water supply mechanism supplies water to the observation box, bubbles emitted by the pipes are observed after the pipes are full of water, so that the airtightness of the pipes is detected, the water supply mechanism recycles the water after detection, a large amount of water is prevented from being taken out of the observation box when the supporting plate ascends and descends, and the supporting plate is provided with a plurality of small holes convenient for the water to permeate through the supporting plate.
