Problems solved by technology

[0004] However, when the PE ball valve and the electrofusion casing are thermally welded, there is currently no fast and effective detection method for the sealing of the welded joint, so the welding effect cannot be judged on the spot, and there is a risk of leakage

Abstract

The invention discloses PE ball valve detecting equipment. The equipment comprises a sleeve, a pushing column and two large base rings sleeving the sleeve; one end of the sleeve is sleeved with a fixed limiting ring, the other end of the sleeve is provided with a sealing plate, a second piston is arranged in the sleeve and connected with the pushing column, the pushing column is provided with an inner column hole and a meter clamping groove, and the meter clamping groove is provided with a pressure meter; a first pressure cavity is internally provided with a return spring, and a first piston is provided with a jacking piece; the fixed limiting ring is provided with a fixed locking hole and a U-shaped locking rod, a movable limiting ring is provided with a movable locking hole for a secondlocking rod to be inserted in, and the axis of the fixed locking hole is parallel to that of the movable locking hole. The PE ball valve detecting equipment has the advantages that a sealing test canbe effectively conducted on the fusion welding joint of a PE natural gas pipe and an electric fusion casing pipe, the operation is simple, the test cost is low, the accuracy of a test result is good,and the fusion welding effect can be judged on site; a limiting rod can be utilized for being in contact with the pipe end of the electric fusion casing pipe, it can be ensured that the equipment is located in a reasonable position, and the accuracy of the test result is ensured.

Description

technical field [0001] The invention belongs to the technical field of valves, and in particular relates to a PE ball valve detection device. Background technique [0002] PE natural gas pipelines have been widely used in the field of natural gas transmission. In PE natural gas pipelines, PE ball valves, electrofusion sleeves, PE natural gas pipes and other structures are all used in large quantities. PE natural gas pipes are the main pipelines. Sleeves are used for the connection between pipeline structures. This is because in PE natural gas pipelines, the most commonly used connection method is thermal fusion (the best overall effect), which requires the use of electrofusion sleeves to achieve thermal fusion. Weld. [0003] The electrofusion sleeve belongs to the prior art in the field of PE pipe valves. It includes a PE pipe body and a heating resistance wire arranged in the inner layer of the PE pipe body. The PE pipe body is also provided with two electrodes, and one ...
