Improved leakage-proof universal half joint assembly

Abstract

The invention provides an improved leakage-proof universal half joint assembly. The improved leakage-proof universal half joint assembly comprises two half joint half bodies, and further comprises at least one socket joint, wherein accommodating cavities for allowing a pipeline to pass through are formed in the two half joint half bodies; a first connecting flange is fixedly arranged on at least one end part of the two half joint half bodies; a first mounting slot is formed in the first connecting flange; a first sealing part is arranged in the first mounting slot; the socket joint is adjacent to the first connecting flange and is arranged on the outer wall of the pipeline in a sleeving mode; one end, close to the first connecting flange, of the socket joint is equipped with a positioning lug boss which can be inserted into the first mounting slot; the positioning lug boss can abut against the first sealing part; one end, away from the first connecting flange, of the socket joint is fixedly equipped with a connector; and the first connecting flange is connected with the connector. The half joint assembly provided by the invention is simple in structure, is convenient to mount, is good in sealing performance and is strong in universality.

Description

technical field [0001] The invention relates to a leak-stopping device for pipelines, in particular to an improved universal anti-leakage half joint assembly. Background technique [0002] The use of pipelines to transmit media brings convenience to human beings, but it also brings troubles.

[0002] The use of pipelines to transmit media brings convenience to human beings, but it also brings troubles. Pipelines are naturally corroded, perforated, dripping, leaking and man-made damage often lead to the problem of pipeline plugging. Huff Festival is a commonly used pipeline plugging device. , Chinese Patent Publication No. CN206299943U discloses a huff joint for emergency repair of ductile ink pipe fittings, which includes two huff joint bodies and several connecting bolts. Seal, the rubber seal includes two left and right gaskets, a left arc-shaped sealing ring and a right arc-shaped sealing ring, the inner shape of the left and right two sealing gaskets is the same The outer shapes match, the upper and lower ends of the left arc-shaped sealing ring and the right arc-shaped sealing ring are combined to form a complete annular sealing ring, and the upper and lower joints of the left arc-shaped sealing ring and the right arc-shaped sealing ring correspond to There is a sealing strip embedded in the body of the Haff Festival

The inner ring of the rubber sealing ring of the half joint can be disassembled and replaced separately, which saves maintenance costs and time, and can avoid leakage at the joint of the half joint, improving the sealing quality and the service life of the overall device, but it still exists as follows Defect: Its structure is poor in versatility and can only be applied to fixed pipe diameters. To meet the construction needs of different pipe diameters, it is necessary to carry different types of half joints, and the upper and lower two half joint bodies tightly wrap the pipe and pass through The bolts are locked tightly. When the pipe expands when it is heated or contracts when it is cooled, it cannot provide deformation space for the pipe. The pipe that expands with heat will stretch the upper and lower half joint bodies apart, resulting in damage to the device, seal failure, and medium leakage.
