Problems solved by technology

[0003] As mentioned in the above paragraphs, during the connection process between the polyethylene connecting ring and the polyethylene pipe using a flaring tool, the end face of the connecting ring will be expanded first when the connecting ring is flared, and the end face of the polyethylene connecting ring will be downward. As a result, the end face of the polyethylene connecting ring cannot be level with the end face of the pipe, resulting in low connection strength and low sealing effect, increasing potential safety hazards

Embodiment 1

[0021] Embodiment 1: An anti-skid tool, including a body 3, a notch is provided on the body 3, and dismantling pipes 1 are arranged on both sides of the notch; upper end faces and lower end faces of the body 3 are respectively provided with upper shoulders 2 , the lower shoulder 5; wherein the extension length of the upper shoulder 2 is less than or equal to the wall thickness b of the fixed connection ring 6; the extension length h of the lower shoulder 5 is between the wall thickness of the fixed connection ring 6 and Between the sum B of the end face thicknesses of the fixed connection ring 6 and the polyethylene pipe material 7 .

Embodiment 2

[0022] Embodiment 2: An anti-slip tool, wherein the cross section of the body 3 is an arc-shaped structure with notches, and the arc-shaped structure is a superior arc. The upper retaining shoulder 2 and the lower retaining shoulder 5 are integrally continuous or independently provided protrusions, and the edges of the protrusions are all arc-shaped. The structures and connections of the remaining parts are the same as those described in any of the foregoing embodiments.

Embodiment 3

[0023] Embodiment 3: A method for anti-slip flaring of the anti-slip tool of the above-mentioned embodiment, the method includes the following steps,

[0024] 1) Set the fixed connection ring 6 on the connection end of the polyethylene pipe 7;

[0025] 2) Set the anti-slip tool on the outer surface of the fixed connection ring 6, and the upper shoulder 2 is connected to the upper end surface of the fixed connection ring 6, and the lower shoulder 5 is connected to the fixed connection ring 6, polyethylene pipe The lower end surface of 7 is connected;

[0026] 3) Use a flaring tool to expand the polyethylene pipe 7 and the fixed connecting ring 6 at the same time. After the flaring is completed, quickly insert the connecting end of the pipe to be connected. After the polyethylene pipe 7 and the fixed connecting ring 6 shrink, remove them Non-slip tool.

[0027] In view of the foregoing embodiments, when the application is in use, its working process and principle are as follow...

Abstract

The invention discloses a memory pipe fitting connecting tool and belongs to the field of pipe fitting connecting pieces. The memory pipe fitting connecting tool is used for connecting and flaring operation of a polyethylene-type pipe and a polyethylene-type connecting piece, and comprises a body. A notch is formed in the body, and the two sides of the notch are provided with detaching pipes; upper blocking shoulders and lower blocking shoulders are arranged on the upper end face and the lower end face of the body correspondingly; and the stretch-out length of each upper blocking shoulder is smaller than or equal to the stretch-out length h of the corresponding lower blocking shoulder. In view of the technical scheme, the end faces of a polyethylene-type connecting ring and the polyethylene-type pipe in the flaring process can be supported through a simple structural form, the polyethylene-type connecting ring is prevented from offsetting downwards, and it is ensured that the end faceof the polyethylene-type connecting ring and the end face of the pipe are horizontal.

Description

technical field [0001] The invention belongs to the field of pipe fitting connectors, and in particular relates to an anti-slip tool for polyethylene pipes and polyethylene row connecting rings and a use method thereof. Background technique [0002] Polyethylene (such as PEX, PERT) materials have a memory function and can recover after being deformed by an external force, so they are widely used in polyethylene pipes and polyethylene connecting rings. Specifically, after flaring the polyethylene pipe and the polyethylene connecting ring with the flaring tool, because of the memory function of the polyethylene product, the connected connecting ring and the pipe can be automatically retracted after being placed for a few minutes Down to achieve a complete sealing effect. [0003] As mentioned in the above paragraphs, during the connection process between the polyethylene connecting ring and the polyethylene pipe using a flaring tool, the end face of the connecting ring will b...
