Clip-press type pipefitting

A compression-type pipe fitting and clamping sleeve technology, applied in the direction of pipe/pipe joint/pipe fitting, pipe connection arrangement, mechanical equipment, etc., can solve the problems of limited knurling depth, scratches on the inner layer of the pipe, and high installation requirements. It can achieve the effect of anti-loosening and anti-leakage, good prevention of metal electrical corrosion, and good connection effect.

Problems solved by technology

[0003] The main disadvantage of the prior art is that the joint body is made of copper metal and the clamping sleeve is made of stainless steel. In order to avoid the aluminum layer of the pipe from contacting the metal body or the stainless steel clamping sleeve, a plastic retaining ring or protective sleeve must be added to prevent dissimilar metals from collapsing. Therefore, the structure of the pipe fittings is complicated and the installation requirements are high; and in application, it is difficult to ensure the stability between the joint body, the clamping sleeve, the plastic retaining ring and the connecting pipe, that is, the integrity is not strong and it is easy to loosen
[0004] In order to overcome the defect of poor integrity, the existing pipe fittings prevent loosening between the parts of the pipe fittings by setting stop ring knurling on the joint body, but due to process limitations, the knurling depth is limited, and it is difficu

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] The structure diagram of the present invention is shown in accompanying drawing 1, accompanying drawing 2.

[0025] The pipe fittings include a joint body 1, a stainless steel clamping sleeve 2, and an elastic sealing ring 3.

[0026] The joint body 1 includes a body end 11 and a body core 12 .

[0027] The joint mouth of the main body core 12 is provided with a wave arc ring groove 123 to avoid scratching the inner wall of the pipe when the pipe is connected and installed; the middle part of the main body core 12 is provided with two rectangular elastic sealing ring grooves 122, and the sealing ring groove Elastic sealing rings 3 are respectively placed between 122; a plurality of undercut sawtooth ring grooves 124 are also provided between the two sealing ring grooves 122 to prevent the axial pull-off of the connected pipes; the tail of the main body core 12 ...

Abstract

This invention provides a clamping tube element including a joint and a clamping cover, in which the joint includes an end and a core, the radial section of the end is greater than the core, said clamping cover is sleeved on the outer circle of the core and a connection structure is set between one end of the cover and the joint end, the joint is made of plastics.

Description

technical field [0001] The invention belongs to the technical field of pipe fittings for pipe material connection, and in particular relates to a clamping type pipe fitting. technical background [0002] Existing compression-type pipe fittings are often used for the connection of aluminum-plastic composite pipes, which mainly include a joint body, a plastic retaining ring, a clamping sleeve and a sealing ring. [0003] The main disadvantage of the prior art is that the joint body is made of copper metal and the clamping sleeve is made of stainless steel. In order to avoid the aluminum layer of the pipe from contacting the metal body or the stainless steel clamping sleeve, a plastic retaining ring or protective sleeve must be added to prevent dissimilar metals from collapsing. Therefore, the structure of the pipe fittings is complicated and the installation requirements are high; and in application, it is difficult to ensure the stability between the joint body, the clamping ...
