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 for emergency repair of pipelines, and in particular relates to a half joint. The present invention comprises two oppositely installed shells, the shells are provided with outwardly extending flanges on both axial sides of the shells, the two flanges are respectively provided with occlusal teeth and occlusal beds, the two shells The body is joined together by occlusal teeth and occlusal bed. It can be seen from the above-mentioned technical solution that the shells in the present invention are installed in an occlusal connection, so not only the installation speed is greatly improved, but also the mutual engagement between the occlusal teeth and the occlusal bed greatly improves the sealing performance of the half joint. At the same time, the high pressure resistance and water hammer resistance of the half section are greatly improved.

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...
