Problems solved by technology

The existing seal mainly includes a first sealing sleeve and a second sealing sleeve, wherein the first sealing sleeve is provided with studs, and when sealing, the studs pass through the wall of the closed container and then pass through the second sealing sleeve. Therefore, it is necessary to open multiple through holes on the wall of the closed container for the studs to pass through, which increases the possibility of groundwater leakage

Abstract

The invention relates to an air bag pipe sealing element. The air bag pipe sealing element comprises a sealing sleeve, sealing flanges and an air bag, the sealing flange is fixedly connected with an opening of an underground container and penetrating from an outer side of the underground container to an inner side of the underground container. An underground pipe is arranged on the inside the sealing flanges, an containing groove is arranged between the underground pipe and the sealing flanges, the air bag is arranged on the inside of the containing groove and sealed in the underground pipe. The sealing flanges which are inside and outside the underground pipe are correspondingly provided with a sealing sleeve, and the sealing sleeve is used for sealing a gap between the sealing flanges and the underground pipe. The air bag pipe sealing element has a compact structure and good flexibility, the sealing performance is greatly improved.

Description

technical field [0001] The invention relates to a pipe seal, in particular to an air bag type pipe seal. Background technique [0002] Some oil pipelines in the gas station have to pass through the connection holes of the closed container to connect with the equipment inside the container. In order to prevent groundwater from entering the closed container and eroding the internal metal joints and other components, pipeline seals are often used to seal the connection holes of the closed container. The existing seal mainly includes a first sealing sleeve and a second sealing sleeve, wherein the first sealing sleeve is provided with studs, and when sealing, the studs pass through the wall of the closed container and then pass through the second sealing sleeve. Therefore, a plurality of through holes need to be opened additionally on the wall of the closed container for the studs to pass through, which increases the possibility of groundwater leakage.
