Simply assembled and disassembled pipeline connecting piece

Abstract

The invention discloses a simply assembled and disassembled pipeline connecting piece. The simply assembled and disassembled pipeline connecting piece comprises an integrally formed join body of a hollow structure, wherein the joint body has a round embedding opening. A first seal groove is formed in the inner side of the embedding opening to embed a first seal ring; the joint body extends outwardat the embedding opening to form a semi-annular pipe sleeve part; a semi-annular pipe sleeve hoop piece is mounted on the pipe sleeve part to form a cylindrical pipe sleeve structure to clamp and sleeve a connected pipeline tightly; rib-line bumps can be formed on the inner wall surfaces of the pipe sleeve part and the pipe sleeve hoop piece and a second seal groove and / or a banding annular groove can be also formed on the inner wall surfaces of the pipe sleeve part and the pipe sleeve hoop piece to mount a second seal ring and / or a banding ring; and the outer side of the wall body is separately connected to at least two lug parts to form a mounting hole, an inner thread may be arranged on the smooth inner wall, a fastening bolt is sleeved in the mounting hole to connect the pipe sleeve hoop piece to the pipe sleeve part.

Description

technical field [0001] The invention belongs to the field of fluid pipeline products, in particular to pipeline connectors for connecting pipe pieces to form a pipe network. Background technique [0002] Pipeline connection is the core process of forming a pipe network. The traditional pipe connection method varies according to the pipe material. The thread connection method used by metal pipes has the longest history. Some metal pipes adopt compression connection, PVC and other plastics and Composite material pipes are mostly heat-sealed. For stainless steel pipe connections that are becoming more and more widely used, in addition to the compression connection and threaded interface connection, some products adopt a direct push connection structure, and the connection of the pipe fittings is realized by locking the connected pipe fittings through the locking piece in the connector. [0003] Due to its excellent corrosion resistance, weather resistance, and clean performanc...

AI Technical Summary

Problems solved by technology

In construction practice, the stainless steel piping system produced by the traditional connection method has the problems of complicated construction technology and high installation space requirements; some connections need to use sealing materials, which increases the source of pollution

For example, the compression connection requires the use of a special compression device and ample operating space to ensure the firmness after pressing; the threaded connection also needs to reserve enough space for operation with a wrench, and when both ends of the pipe are threaded. It will become more difficult to disassemble and replace; the direct push connection structure has the disadvantages of high installation requirements, easy leakage when the operation is not in place, and inability to disassemble when both ends are direct push connection structures

Above all, various defects increase the use cost of stainless steel pipes and limit the scope of use. Although those skilled in the art have made some modifications to the pipe connection structure, it is more to enhance the sealing performance and connection stability. For installation There is no qualitative improvement in the science and operability of the process
