Embodiment Construction

[0017] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0018] combine Figure 1 to Figure 3 As shown, the pipe connection assembly of the present invention is schematically shown, wherein the pipe 1 includes a metal layer 11 and a plastic layer 12 arranged in sequence from the inside to the outside and attached to each other, and the metal layer 11 and the plastic layer 12 are adhesively connected. The pipe 1 connection assembly includes a connecting pipe 2 and a sealing pipe 3. The outer diameter of the sealing pipe 3 is smaller than the inner diameter of the connecting pipe 2, and the outer diameter of the sealing pipe 3 is smaller than the inner diameter of the pipe 1. Therefore, the end of the pipe 1 can be sleeved At one...

Abstract

The invention relates to the field of pipeline connecting devices, in particular to a tubular product connecting assembly. The end part of a tubular product and the end part of a connecting pipe are separately arranged at two ends of a sealing pipe in a sleeving manner, a sealing part is arranged on the outer side wall of the sealing pipe in a surrounding manner, and two ends of the sealing part are in abut joint to the end surface of a metal layer and the end part of the connecting pipe, separately, to prevent a condition that the metal layer and a plastic layer of the tubular product are separated as water in the tubular product, the connecting pipe and the sealing pipe corrodes the end surface of the tubular product, so that the water supply quality is ensured. Two ends of the connecting pipe can be connected to the sealing pipe and the tubular product, so that the two tubular products are connected and communicate.

Description

technical field [0001] The invention relates to the field of pipe connection devices, in particular to a pipe connection assembly. Background technique [0002] Plastic-lined metal composite pipes on the market are polypropylene-lined stainless steel pipes or polypropylene-lined copper pipes. Plastic-lined metal composite pressure pipes are co-extruded from metal layers, rubber layers, and plastic layers, that is, between the metal and plastic layers. It is bonded by hot melt adhesive. There are two existing connection methods, one is to use ordinary PPR pipe fittings, the defect is that the plastic and metal bonding layer at the end of the pipe fittings will be corroded by water, which will cause the metal separation layer to affect the use; the other is to use special PPR pipe fittings to connect There is a metal bushing in the middle, but there will be a gap between the metal bushing and the metal layer of the pipe. If there is a gap at the end of the pipe, water will in...
