Pipe connector

Abstract

The invention provides a pipe connector and relates to a connector. The pipe connector is used for connecting a pipe A and a pipe B and comprises a threaded connector with external threads and nuts matched with the threaded connector; the inside of the threaded connector is provided with a ring-shaped groove and a transverse rotation-stopping groove; the connecting end of the pipe A is provided with a ring-shaped boss by which the connecting end can be embedded in the ring-shaped groove of the threaded connector; the connecting end of the pipe B is provided with a ring-shaped boss by which thenuts cannot fall off from the pipe B; and the connecting opening of the pipe B is provided with a groove, and an O-shaped ring in the groove is internally connected with the pipe A by hermetic sealing. The pipe connector has the advantages of thoroughly solving the problems of manufacturing defects and leakage occurring in technological processes such as welding, cleaning and the like, achievingaims of internal homogeneity, no welding, no cleaning, no pollution and no leakage of the whole pipe as well as material conservation, low cost, no internal oxidation and the like.

Description

Technical field [0001] The invention relates to a joint piece, in particular to a heading riveting joint piece for connecting two pipelines. Background technique [0002] Pipe joints are intermediate pieces that connect two pipes. Take air-conditioning pipes as an example. At present, all domestic air-conditioning pipes are connected by copper threaded joints, nozzles and nuts. The pipes and joints are welded to form an integrated structure. This connection method has the following defects: 1) In order to improve the welding quality, each joint is made of the same quality copper material. Due to the current continuous increase in copper prices, the production cost of the enterprise has been greatly increased; 2) During the welding process , It is easy to cause poor sealing performance of local welds and easy to cause leakage; 3) After welding, the joints of the pipe fittings need to be cleaned. Generally, the parts to be cleaned are inside the pipe fittings or gaps, which brings ...

AI Technical Summary

Problems solved by technology

This connection method has the following defects: 1) In order to improve the welding quality, each joint is made of homogeneous copper material. Due to the current continuous rise in copper prices, the production cost of the enterprise has been greatly increased; 2) During the welding process , it is easy to cause poor sealing performance of local welding, which is easy to cause leakage; 3) After welding, the connection of pipe fittings needs to be cleaned. Generally, the parts to be cleaned are inside or in the gaps of pipe fittings, which brings difficulty to the cleaning process; 4 ) The cleaning fluid is mostly made of strong acid. The surface of the workpiece and the thread will be corroded to varying degrees, and more importantly, the environment will be damaged.
