Problems solved by technology

Pipe variable diameter connection is to connect two pipes with different diameters, that is, a thin pipe and a thick pipe. Compared with the connection of two pipes with the same diameter, the connection between two pipes with different diameters is more It is easy to leak, so more attention should be paid to the sealing performance of the sealing ring, and the sealing ring in the prior art cannot be further attached to the pipe wall after installation. It is difficult to meet the requirements of sealing performance when used in pipeline variable diameter connection, and when the existing sealing ring is used for pipeline variable diameter connection, it is very troublesome to cooperate with the connector, and the operation is inconvenient, which will reduce the reliability of the pipeline connection. work efficiency

Abstract

The invention discloses a sealing ring, a connecting piece and a use method for pipe variable diameter connection, which belong to the technical field of sealing rings, and can be provided with a special sealing ring assembly and a connecting piece used in conjunction with the sealing ring assembly, and the sealing ring The ingenious cooperation between the components and the connector components makes the operation of the pipe connection convenient and simple, which can speed up the speed of the pipe connection, thereby improving the work efficiency, and after the pipe connection is completed, the elastic main sealing ring can spontaneously expand. Furthermore, the elastic main sealing ring is further close to the outer wall of the thin tube and the inner wall of the thick tube, thereby significantly strengthening the sealing performance of the joint of the pipeline and improving the practicality. When the pipeline is connected, under the premise of not hindering the circulation of the pipeline, the sealing cylinder for the thin tube and the sealing ring for the thick tube can respectively offset the connecting ends of the thin tube and the thick tube, thereby further strengthening the sealing of the joint.

Description

technical field [0001] The invention relates to the technical field of sealing rings, and more specifically relates to a sealing ring, a connecting piece and a use method for pipe variable diameter connection. Background technique [0002] The seal ring is a part used to strengthen the seal. There are various types of seal rings. According to the material, the common seal rings are: nitrile rubber seal ring, hydrogenated nitrile rubber seal ring, silicone rubber seal ring, fluorine Rubber sealing rings, fluorosilicone rubber sealing rings, EPDM rubber sealing rings, neoprene rubber sealing rings, butyl rubber sealing rings, acrylic rubber sealing rings, etc., sealing rings of different materials have different advantages and disadvantages, It can be applied to different usage scenarios respectively. [0003] In the pipeline connection, in order to prevent leakage at the joint, it is also necessary to use a sealing ring to strengthen the sealing of the joint. Pipe variable ...
