Embodiment Construction

[0016] like Figure 1~5 As shown, a Huff joint includes two oppositely installed housings 30, and both sides of the housing 30 along the axial direction are provided with outwardly extending flanges 31, and the two flanges 31 are The occlusal teeth 311 and the occlusal bed 312 are respectively provided, and the two shells 30 are connected together by the occlusal teeth 311 and the occlusal beds 312 interlocking.

[0017] The shapes of the two housings 30 are the same, that is, each housing 30 is provided with two flanges 31, one flange 31 is provided with occlusal teeth 311, and the other flange 31 is provided with an occlusal bed 312, such as figure 2 , 4 , 5 shown. During construction and installation, the two housings 30 are installed opposite to each other, and the occlusal teeth 311 of one housing 30 are engaged with the occlusal bed 312 of the other housing 30, and then the bolts are sequentially passed through the two housings 30 opposite to each other. Flange edge...

Abstract

The invention belongs to a device used for emergency repair of a pipeline, which in particular relates to a Hafu joint. The Hafu joint comprises two casings which are oppositely installed, wherein both sides of the casings along an axial direction are both provided with flange sides extending outwards, the positions of the two flange sides are respectively provided with an engagement tooth and an engagement bed, and the two casings are connected together by mutual engagement of the engagement teeth and the engagement beds. By the technical scheme, the casings in the invention adopt engagement type connection and installation, so that installation speed is greatly enhanced, and the sealing property of the Hafu joint is greatly enhanced by mutual engagement of the engagement teeth and the engagement beds. Meanwhile, the high-pressure resistance performance and the water hammer resistance performance of the Hafu joint are also enhanced greatly.

Description

technical field [0001] The invention belongs to a device for emergency repair of pipelines, and in particular relates to a half joint. Background technique [0002] Water pipes, gas pipes, steam pipes, and petrochemical pipelines are widely used in production and life. These pipes may leak or be damaged due to improper maintenance, geological subsidence, and external impact. When repairs are required, Ha Seal and wrap the leakage or damage of the pipeline. [0003] The existing Haff joint has poor sealing performance, high pressure resistance and water hammer resistance, and needs to be improved urgently. Contents of the invention [0004] The purpose of the present invention is to provide a half joint, which has good sealing performance and is easy to install and construct. [0005] In order to achieve the above object, the present invention adopts the following technical solutions: a half joint, including two oppositely installed shells, and the two sides of the shells...
