Leakproof rubber ring for gas pipeline

Abstract

The invention relates to a leakproof rubber ring for a gas pipeline. The rubber ring comprises a first seal ring, a second seal ring, an external limiting ring and an internal limiting ring, wherein the external limiting ring and the internal limiting ring are located between the first seal ring and the second seal ring, the first seal ring and the second seal ring are detachably connected, a first suction disc and a first connecting ring are arranged on the first seal ring, a first through hole is formed in a middle position of the first seal ring, a second suction disc and a second connecting ring are arranged on the second seal ring, and a second through hole is formed in a middle position of the second seal ring. An internal thread is arranged on the inner wall of the first connectingring, and an external thread is arranged on the outer wall of the second connecting ring. According to the leakproof rubber ring for the gas pipeline, the sealing property between the seal rings and the pipelines is better by means of the suction disc arranged thereon, and it is convenient to rotate between the pipeline and the pipeline during detachment, so that a condition that it is unable to split the two connecting pipelines conveniently as the seal rings are adsorbed to the pipelines can be prevented.

Description

technical field [0001] The invention belongs to the technical field of pipeline sealing, and in particular relates to a rubber ring for preventing leakage of gas pipelines. Background technique [0002] The gasket is made of paper, rubber sheet or copper sheet, which is placed between two planes to strengthen the sealing material, and is a sealing element arranged between the static sealing surfaces to prevent fluid leakage. [0003] Pad is two mechanical seals between object, usually being under pressure between two objects that prevent, the leakage of naturally expanding with heat and contract with cold of burn into and pipeline. Since machined surfaces can never be perfect, irregularities can be filled with shims. Gaskets are usually made of sheet materials such as paper pads, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, fiberglass, or plastic polymers such as Teflon. Gaskets for certain applications may contain asbestos. A washer is a hole (us...

Problems solved by technology

[0004] The common rubber ring used for gas pipelines in the market is a kind of gasket, and its function is mostly used to seal the gap between the pipelines, to play the role of sealing, increasing friction and buffering, and the common ones on the market The rubber ring is just an annular gasket made of rubber, and the connection between it and the pipe is not particularly close. The two only use mutual pressure to make the gasket and the pipe contact, so as to achieve the sealing effect. , but if there are uneven places on the pipe, the sealing performance of the rubber ring will be greatly reduced
