Fast joint for pipelines

Abstract

The invention discloses a fast joint for pipelines. The fast joint for the pipelines comprises a joint body, two cap bodies and two clamping sleeves. The joint body is a hollow pipe body. Threaded segments are arranged on the outer walls of the edges of the two ends of the joint body. The two cap bodies are correspondingly connected with threads of the two ends of the joint body. Each cap body is hollow, the inner diameters of the two ends of each cap body are different, the inner wall of one end of each cap body is provided with an inner thread connected with the joint body in a threaded and matched manner, the inner wall of the other end of each cap body is a conical surface, the middle of each clamping sleeve is hollow, annular protruding teeth are arranged on the inner wall of each clamping sleeve, and the outer wall of each clamping sleeve is a conical surface; and each clamping sleeve is arranged at the position of the hollow inner cavity of the corresponding cap body and located at one side of the end of the joint body. The hollow portion of the joint body, the hollow portions of the cap bodies and the hollow portions of the clamping sleeves communicate with one another. Through design of the annular protruding teeth and expanding grooves, when the fast joint for the pipelines is used, inserting and mounting of pipe bodies can be achieved fast; and due to the design of the conical surfaces of the outer walls of the clamping sleeves, the conical surfaces of the inner walls of the cap bodies, the expanding grooves and sealing rings, self-locking and self-sealing can be achieved after the pipe bodies are jointed.

Description

technical field [0001] The invention relates to the technical field of pipeline maintenance accessories, in particular to a pipeline quick joint. Background technique [0002] At present, during the use of tap water pipelines, due to various reasons, partial ruptures of water pipes often occur, resulting in the loss of a large amount of precious water resources and great waste. When repairing tap water pipelines, the partially ruptured old Remove the whole water pipe, replace it with a new water pipe, and reconnect the tap water pipe with the pipe joint. This maintenance method not only causes great waste, but also the installation of new water pipes is laborious and time-consuming; [0003] And when laying and installing pipelines, sometimes a single pipe body is not long enough, and when multiple pipe bodies are required to be spliced ​​and extended in length, there is a lack of pipe connectors and pipe splicing joints that are convenient to continue and have good sealing...

[0002] At present, during the use of tap water pipelines, due to various reasons, partial ruptures of water pipes often occur, resulting in the loss of a large amount of precious water resources and great waste. When repairing tap water pipelines, the partially ruptured old Remove the whole water pipe, replace it with a new water pipe, and reconnect the tap water pipe with the pipe joint

This maintenance method not only causes great waste, but also the installation of new water pipes is laborious and time-consuming;

[0003] And when laying and installing pipelines, sometimes a single pipe body is not long enough, and when multiple pipe bodies are required to be spliced ​​and extended, there is a lack of pipe connectors and pipe splicing joints that are convenient for splicing and good sealing performance.
