Embodiment Construction

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0021] Such as Figure 1-3 As shown, a half-section housing includes two semi-cylindrical housings 1 installed up and down oppositely at the leaking place of the pipeline 6, and the opposite end surfaces of the two housings 1 are respectively provided with sealing gaskets 2 for embedding. The installation groove 3 is provided with a protrusion 4 for increasing the pressure of the gasket 2 , and the protrusion 4 is located in the middle of the installation groove 3 close to the opening of the housing 1 . The pressure of the bump 4 on the sealing gasket 2 is doubled according to the national standard, preventing the sealing gasket 2 from being washed away from the housing 1 due to excessive pressure, and effectively r...

Abstract

The invention relates to a Hough section shell. The Hough section shell comprises two semi-cylindrical shell bodies which are installed at the pipeline leakage positions in an up-down opposite manner; the opposite end faces of the two shell bodies are each provided with an installing groove for a sealing gasket to be embedded in; and convex blocks used for increasing the pressure of the sealing gaskets are arranged in the installing grooves. The Hough section shell has the beneficial effects that the pressure on the sealing gaskets is doubled on the national standard, it is prevented that because the pressure borne by the sealing gaskets is too large, the sealing gaskets are washed away from the shell bodies, and pipeline leakage stoppage is effectively achieved.

Description

technical field [0001] The invention relates to the field of pipeline plugging, in particular to a half joint casing. Background technique [0002] The half-joint is a kind of pipeline leak plug commonly used. The existing half-joint shell includes two semi-cylindrical shells installed up and down oppositely at the leaking place of the pipeline. The opposite end surfaces of the two shells are respectively equipped with In the mounting groove for inserting the gasket. With the above structure, the gasket is easy to slide outward under the action of pipeline pressure, and even is washed away from the housing by the pressure in the pipeline, resulting in failure to seal and plugging. Contents of the invention [0003] To sum up, in order to overcome the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a half joint housing. [0004] The technical solution of the present invention to solve the above-mentioned technical p...
