Compression joint flared plastic pipe

Abstract

The invention relates to the technical field of pipes, and concretely relates to a compression joint flared plastic pipe. The compression joint flared plastic pipe comprises a pipe, a communicated pipe hole is formed in the inner cavity of the pipe, the pipe comprises a joint and a flared joint, a part, close to the outer wall of the middle, of the pipe is in threaded connection with a nut, the nut comprises a joint sleeve and a flared sleeve, the inner wall of the joint sleeve is in threaded connection with the outer wall of the joint, the flared sleeve is in threaded connection with the outer wall of the flared joint, the outer wall of the joint is in threaded connection with a fixing block, a limiting rod is arranged between the fixing block and the joint sleeve, a buffer block is fixedly connected to the end part of the limiting rod, a buffer spring is arranged at the end part of the buffer block, the outer wall of the flared joint is in threaded connection with a protective sleeve, the outer wall of the protective sleeve is in threaded connection with a hexagon nut, the outer wall of the protective sleeve is in threaded connection with the inner wall of the flared sleeve, a sound insulating cavity is arranged in the inner cavity of the protective sleeve, and sound insulating cotton is arranged in the inner cavity of the sound insulating cavity. The compression joint flaredplastic pipe has the advantages of simple structure, easiness in production, resistance to impact force, effectiveness in prevention of the nut from shaking, keeping of the stability, and sound insulation.

Description

technical field [0001] The invention relates to the technical field of pipe fittings, in particular to a ferrule-type connecting flared plastic pipe fitting. Background technique [0002] Pipe joints are parts that connect pipelines or install pipelines on hydraulic components in hydraulic systems. This is a general term for connectors that can be assembled and disassembled in fluid passages, mainly including: welded, ferrule and flared Applicable media for flared and flared pipe joints: oil, water, gas and other non-corrosive or corrosive medium pipe joints (the representative manufacturer is Shanghai Tongyang Pipe Fittings Co., Ltd.), and the specification requirements for matching steel pipes are relatively flexible After being welded with the pipeline, it has the characteristics of firm connection and good sealing performance, so it is widely used in oil refining, chemical industry, light industry, textile, national defense, metallurgy, aviation, shipbuilding and other s...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a ferrule-type connection flared plastic pipe fitting to solve the problems that the common flared pipe body cannot resist impact force, the connection between the nut and the pipe body is not firm, and the sound insulation cannot be solved.
