Pipeline rapid connector easy to dismount and mount

Abstract

A pipeline rapid connector easy to dismount and mount comprises a connector body and a gland connected with the connector body in a matched mode. One side of the gland is in a funnel shape. The gland is internally provided with a first supporting pad, a gasket, a first sealing ring and a second sealing ring. One end of the first supporting pad abuts against the connector body through the first sealing ring, and the other end of the supporting pad abuts against the gasket through the second sealing ring. The gasket is formed by combining at least two arc gasket blocks through an elastic piece in a bonding mode. The inner wall of the gasket is provided with a second annular groove matched with a convex ring on a pipe. When the pipeline rapid connector is used, a port of the pipe is flush with a port of the connector body on the same side all the time or located outside the connector body all the time. The pipeline rapid connector has the advantages of being easier to dismount and mount and more convenient to use.

Description

Technical field [0001] The invention relates to the field of quick connection pipe joints, in particular to a pipe quick connection head that is easy to disassemble and assemble. Background technique [0002] At present, quick-connect pipe joints are developing rapidly. Because of their easy installation, low construction difficulty, time-saving and lower cost of use, quick-connect pipe joints have gradually replaced the traditional welding connection between pipelines and have been widely used in pipelines. Connection system; however, the disassembly of the existing connector requires the pipe body to be withdrawn from the connector to realize the disassembly to complete the repair and maintenance of the connector. It is very troublesome. In order to solve the above problems, someone has developed a An easy-to-disassemble and quick-connect pipe joint to realize that the entire connector can be dismantled without the need to withdraw the pipe. Its structure includes a connector b...

[0002] At present, quick-connect pipe joints are developing rapidly. Because of their convenient installation, low construction difficulty, time-saving and lower cost of use, quick-connect pipe joints have gradually replaced the traditional welding connection between pipes and are widely used in pipelines. Connection system; however, the disassembly of the existing connector requires the pipe body to be withdrawn from the connector to achieve disassembly to complete the repair and maintenance of the connector, which is very troublesome. In order to solve the above problems, someone has developed a An easy-to-disassemble quick-connect pipe joint, so that the entire joint can be disassembled without withdrawing the pipe. Its structure includes a joint body and a gland that cooperates with the joint body. One side of the gland is Funnel-shaped, a first support pad, a gasket, a first seal ring and a second seal ring are arranged in the gland, and one end of the first support pad abuts against the connector body through the first seal ring, so The other end of the first support pad is opposed to the gasket through the second sealing ring, and the gasket cooperates with the gland to form an annular groove matching the convex ring on the pipe body. When in use, the port of the pipe body is always flat flush with the connector body port on the same side, or always outside of said connector body

[0003] However, in the course of the test, people found that because the gasket is a one-piece inner wall with a cylindrical structure and is restricted by the protruding ring on the pipe body, it is very difficult to install and disassemble the gasket during use. Usually, it is necessary to destroy the structure of the gasket to disassemble it, which takes a lot of time and high cost, so it is very troublesome
