Problems solved by technology

The second generation of products needs to be sealed with polytetrafluoroethylene and other packing during installation, which will be inconvenient to use
[0004] However, the joint provided by this patent does not solve the problem of the need to use polytetrafluoroethylene caulking, and the joint still requires two people to be installed smoothly

Abstract

The invention discloses a connecting method for a pipeline joint. The pipeline joint comprises at least one external O-shaped ring, at least one metal connector, a metal joint body and at least one metal wedge-caulking cap, wherein the connector and the joint body are connected to each other; and an annular protrusion protruding towards the central axis of the pipeline joint is integrally arrangedon the radial inner wall of the connector, and the wedge-caulking cap can be arranged at the radial outer side of the abutting end of the connector in a sleeved mode. The connecting method comprisesthe steps that force is applied by means of a tool, so that the wedge-caulking cap is locked towards the axial end where the connector of the pipeline joint is located, the annular protrusion is pressed inwards on the outer wall of the end of the metal pipeline, and a first defensive line for connection and sealing of the pipeline joint and the metal pipeline is formed. The connecting method provided by the invention is good in sealing effect; a corresponding pipeline joint product is light, so that the raw material cost is greatly saved; the wedge-caulking cap does not fall off before installation, so that the installation is convenient; and the overall test performance of the pipeline joint is very good.

Description

technical field [0001] The invention belongs to the field of pipeline connectors, and in particular relates to a pipeline joint used for connecting metal pipelines and a connection method thereof. Background technique [0002] Existing metal joints for connecting metal water pipes generally include two generations of products. In the first generation of joint products, the sealing structure used to prevent water leakage is a rubber sealing ring, which belongs to the soft sealing structure. The sealing ring in the product is prone to aging and damage, and high temperature is easy to release toxins, which is not environmentally friendly. The connection between the second-generation joint product and the metal water pipe is a clamping type, which is compacted and sealed, and belongs to the hard-sealed structure. The second-generation products need to be sealed with packing such as polytetrafluoroethylene during installation, which will be inconvenient to use. [0003] For ex...
