Embodiment 1

[0022] Such as figure 1 As shown, a disassembled mechanically connected insulating joint with a soft rubber layer of the present invention includes two sleeves 6 and a sleeve 9, the sleeves 6 and 9 are cylindrical hollow pipes, and the sleeve 6 The diameter of the cavity is 5 cm, the thickness of the sleeve 6 is 1 cm, and the length of the sleeve 6 is 30 cm; the diameter of the cavity of the sleeve 9 is 6 cm, the thickness of the sleeve 9 is 1 cm, and the length of the sleeve 9 is 25 cm. The two casings 6 and the sleeve 9 are provided with a soft rubber layer 7, which improves the material of the contact surface and protects the casing 6, the sleeve 9, and the pipeline, avoiding the need for welding in traditional joints. Due to the rough welding point, the uneven surface during connection and use will damage the material on the surface of the pipe, which is not conducive to anti-corrosion insulation protection and causes a great degree of waste; the soft rubber layer 7 adopts...

Embodiment 2

[0024] Such as figure 1 As shown, a disassembled mechanically connected insulating joint with a soft rubber layer of the present invention includes two sleeves 6 and a sleeve 9, the sleeves 6 and 9 are cylindrical hollow pipes, and the sleeve 6 The diameter of the cavity is 5 cm, the thickness of the sleeve 6 is 1 cm, and the length of the sleeve 6 is 30 cm; the diameter of the cavity of the sleeve 9 is 6 cm, the thickness of the sleeve 92 is 1 cm, and the length of the sleeve 9 is 25 cm. The sleeve 9 and the two sleeves 6 are threadedly connected, the outer diameter of the thread is 6cm, the inner diameter of the thread is 5cm, the middle diameter of the thread is 5.5cm, the lead of the thread is 1cm, the number of threads is 5, and the helix angle is 30 The threaded connection is the physical connection between two mechanical blocks, which can be disassembled, so as to avoid the damage of any part, because the traditional joint joint adopts welding connection, because the we...

Embodiment 3

[0025] The difference between embodiment 3 and embodiment 1,2 is:

[0026] The present invention is a disassembled mechanically connected insulating joint with a soft rubber layer, including two sleeves 6 and a sleeve 9, both of which are cylindrical hollow tubes, and the cavity of the sleeve 6 The diameter is 10cm, the thickness of the sleeve 6 is 2cm, and the length of the sleeve 6 is 40cm; the diameter of the cavity of the sleeve 9 is 12cm, the thickness of the sleeve 9 is 2cm, and the length 9 of the sleeve 2 is 35cm. The temperature of the working environment is 50 degrees, and the connection method is spline connection. The outside of the sleeve 6 is an internal spline, and the inside of the sleeve 9 is an external spline; The tooth shape is a triangular cylinder, the triangular surface of the triangular cylinder has a base of 0.6 cm and a height of 0.9 cm; the length of the flower teeth is 5 cm. The two casings 6 and the sleeve 9 are provided with a soft rubber layer 7 i...

Abstract

A detachable mechanically connected insulation joint with a soft adhesive liner, comprising: two sleeves (6) and a tube (9) both of which are provided with an inner soft adhesive liner. The sleeves (6) and the tube (9) and the soft adhesive liners (7) are each in the shape of a cylindrical hollow tube, and the soft adhesive liners (7) cover the inner sides of the sleeves (6) and the tube (9) by means of injection molding, wherein the outer walls of the soft adhesive liners (7) are seamlessly connected to the inner walls of the sleeves (6) and the tube (9). The surfaces of the sleeves (6) and the tube (9) are provided with a layer of insulating adhesive, and the tube (9) and sleeves (6) are connected by a screw connection or a splined connection, with the connection portion thereof being in the shape of a trapezoid, and the surface thereof being the upper base and the two sides of the trapezoid. By providing the soft adhesive liners (7) in the sleeves (6) and the tube (9) of the insulation joint, the material of the contacting surface is improved, achieving protection of the tube, and since the mechanical components are connected with one another physically and form an internal connection structure, the outward appearance thereof is not affected. The connection is a cold connection, and thus does not result in high temperature damage to the insulation material.

Description

technical field [0001] The invention relates to the field of insulating joints, in particular to a disassembled mechanically connected insulating joint with a soft rubber layer. Background technique [0002] The corrosion risk of pipelines on industrial installations is generally greater than in long distance pipelines because in most cases the pipelines will form corrosion cells with the reinforced concrete foundation. Area cathodic protection can be used in various types of industrial plant areas to overcome this corrosion hazard, using methods similar to local cathodic protection. The protected area is unlimited, i.e. there is no electrical insulation between the pipes and connecting and branching pipes. The purpose of partial cathodic protection is not only to compensate the battery current of the external cathodic structure, but also to make the protected structure fully cathodically polarized, so as to meet the requirements of cathodic protection guidelines. In local...
