Claw pressing type connecting piece of stainless steel pipeline

Abstract

The invention discloses a claw pressing type connecting piece of a stainless steel pipeline, which comprises an elbow, wherein the elbow is internally provided with through holes, and a left joint and a right joint are arranged on the left end and the right end of the elbow; a connecting pipe is arranged in the right interface; the external wall of the connecting pipe is sequentially sheathed with a seal ring, a fixing ring and a nut; the nut is in threaded connection with the right interface; the right interface is provided with a positioning groove; the fixing ring is provided with a positioning boss matched with the positioning groove; the right interface and the fixing ring are connected in a limit mode by matching the positioning groove with the positioning boss; and the side of the top of the fixing ring is provided with a fixed claw tilted inwards along the axial direction. The connecting piece of the invention has the advantages of simple and reasonable structural design, good sealing property, convenient installation, long service life and more firm connection.

Description

technical field [0001] The invention relates to a claw pressure type stainless steel pipeline connection piece for connecting gas, water or other liquids. Background technique [0002] At present, the pipeline connectors used to communicate with gas, water or other liquids on the market include direct connectors, elbows, tees, etc. The connectors in the form of screw connections are provided with threads. Pad seal, or cover the thread with expansion materials such as raw material tape, and tighten the connection through the fastening screw to prevent leakage. However, because the leather pad is easy to age and has a short service life, it must be replaced frequently. The material is also troublesome to install and maintain. In addition, due to structural design defects of similar products currently on the market, when one end of the pipe is fixed and then the other end is installed and fixed, the rotation of the pipe will cause the newly fixed end to loosen. , so in the con...

[0002] At present, the pipeline connectors used to communicate with gas, water or other liquids on the market include direct connectors, elbows, tees, etc. The connectors in the form of screw connections are provided with threads. Pad seal, or cover the thread with expansion materials such as raw material tape, and tighten the connection through the fastening screw to prevent leakage. However, because the leather pad is easy to age and has a short service life, it must be replaced frequently. The material is also troublesome to install and maintain. In addition, due to structural design defects of similar products currently on the market, when one end of the pipe is fixed and then the other end is installed and fixed, the rotation of the pipe will cause the newly fixed end to loosen. , so in the construction process, two or more workers need to cooperate to fix both ends of the pipe at the same time to complete, which increases the labor input and increases the installation cost. At the same time, the technical requirements for the construction personnel and the installation accuracy are higher.
