Problems solved by technology

However, the gaskets of the existing leak stoppers for pipe fittings are poor in high pressure resistance and water hammer resistance, prone to local rollover and high-pressure fluid rushing out accidents, resulting in failure of the seal of the leak stopper for pipe fittings, so improvement is urgently needed

Embodiment Construction

[0015] like Figures 1 to 8 As shown, an environmental protection gasket for a leak stopper for pipe fittings includes sealing rings 10 arranged at the ends of the gasket, and sealing sleeves 20 connected to each other are arranged between the sealing rings 10 .

[0016] The sealing sleeve 20 can be set as a whole, or can be set as several sealing strips or sealing ribs connected between the sealing rings 10 .

[0017] The edge portion of the sealing sleeve 20 facing the outside of the leak stopper is provided with a positioning hole 22 to facilitate its installation and fixing.

[0018] Since the sealing sleeve 20 in the present invention is provided with a positioning hole 22 to facilitate its installation and fixing, after the sealing gasket is placed on the casing of the pipe fitting leak stopper, the positioning hole 22 on the sealing gasket coincides with the bolt hole on the casing , the bolts pass through the bolt holes on the casing and the positioning holes 22 on th...

Abstract

The invention relates to the technical field of pipeline rush repair, in particular to an environmental-protection sealing gasket of a pipe fitting leak stopper. The environmental-protection sealing gasket of the pipe fitting leak stopper comprises sealing rings arranged at the end of the sealing gasket, and integral sealing sleeves which are connected with each other are arranged between the sealing rings. In the invention, since the integral sealing sleeves which are connected with each other are arranged between the sealing rings, the contact area of the sealing gasket and a shell is greatly increased, which not only enhances the integrity of the sealing gasket but also increases the sealing area of the sealing gasket and the shell, and therefore, the high pressure resistance and the water hammer resistance of the sealing gasket are improved, thereby the sealing performance of the whole sealing gasket is improved; meanwhile, the work reliability of the pipe fitting leak stopper is also improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline emergency repair, and in particular relates to an environmental protection gasket for a leak stopper for pipe fittings. 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 it is light, a pipe fitting leak plug is usually used to seal and wrap the leakage or damage of the pipeline. [0003] The structure of the existing leak stopper for pipe fittings includes oppositely installed shells and sealing gaskets arranged on the shells. When installed, the sealing gaskets on the two shells are opposed to each other to improve the sealing performance. However, the gaskets of the existing leak stoppers for pipe fittings have poor high pressure resistance and water hammer resistance, and are prone to partial rollo...
