Abstract

The utility model discloses a pipe fitting of a composite copper water pipe. A circle of accommodating space is arranged at the interface position between the acrylic external layer and the copper inner liner, and a composite copper water pipe connected with the pipe fitting is inserted into the accommodating space at the interface position; the copper inner liner of the pipe fitting is embedded into the copper pipe of the composite copper water pipe, and the acrylic external layer of the composite copper water pipe is covered by the acrylic external layer of the pipe fitting; the pipe fitting is composed of a straight connector, a bend connector, and a T-shaped connector, and a brass external screw thread opening can be embedded at the other end of the interface. The utility model has the advantages that the water supply system is changed into a whole copper pipeline system, which solves the heat expansion and cold contraction problems of two kinds of materials with the different heat transmission coefficient, increasing the strength of the pipeline system; besides, the utility model has the advantages of convenient and simple installation, and convenient and simple maintenance, without needing the specific tools, and plastic-removing treatment.

Description

The pipe fitting of complex copper water pipe
Technical field:
The utility model relates to a kind of pipe fitting of complex copper water pipe, and particularly a kind of interface position is provided with the pipe fitting of a circle containing space.
Background technique:
The complex copper water pipe of Xiao Shouing is generally copper and polyacrylic composite pipe in the market, the PPR copper plumbing is arranged into, all adopting the PPR pipe fitting with the supporting pipe fitting of compound copper water pipe is the polypropylene pipe fitting, but whole water system is like the non-copper of copper, there is part polypropylene pipe fitting to add copper liner in order to address this problem to adopt, and have two kinds with complex copper water pipe ways of connecting, the formula that crashes and mouthing, the what is called formula of crashing is that the copper pipe mouth of complex copper water pipe crashes with the mouth of pipe of pipe fitting copper liner and is connected, though it is easy for installation, but two kinds of material heat-transfer coefficient differences, under the bigger situation of the temperature difference, the degrees of freedom of expanding with heat and contract with cold can be given the hidden danger that in the future stays, after mouthing is about to the outer stripping of polypropylene of complex copper water pipe, the naked copper pipe is inserted in the pipe fitting copper liner,, need special tool and technology to take off when installing and mould processing though solved the problem of expanding with heat and contract with cold.The purpose of this utility model is exactly in order to overcome the defective of above-mentioned prior art, and the utility model is designed a kind of pipe fitting of complex copper water pipe series.
Summary of the invention:
Formation of the present utility model mainly comprises: be provided with one at the interface position between the skin of polypropylene and the copper liner and enclose containing space, the complex copper water pipe that is connected with pipe fitting inserts the containing space at interface position, the copper liner setting-in of pipe fitting is gone in the copper pipe of complex copper water pipe, the copper pipe of complex copper water pipe is enclosed within outside the copper liner of pipe fitting, the skin of the polypropylene of complex copper water pipe is by the skin of pipe fitting polypropylene parcel, and pipe fitting comprises straight joint, elbow connection, T junction.The utility model has the advantages that: make water system become full copper tube system, solved two kinds of problems of expanding with heat and contract with cold that the material heat-transfer coefficient is different, and increased the intensity of pipe-line system, and installation, maintenance is convenient, simple, do not need special tool, do not need to take off and mould processing.

The layer of 1 polypropylene, 2 copper liners, 3 brass external thread wire mouths, 4 containing spaces, the polypropylene skin of 5 complex copper water pipes, the copper pipe of 6 complex copper water pipes
Embodiment:
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Embodiment one:
The skin 1 of pipe fitting adopts the polypropylene material to be compound on the copper liner 2, pipe fitting includes straight joint, elbow connection, several pipe connecting components of T junction, be provided with one at the interface position between the skin 1 of polypropylene and the copper liner 2 and enclose containing space 4, this containing space 4 is the circular groove outside the copper liner 2 that is surrounded on pipe fitting, its degree of depth is 12~14mm, width is the polypropylene outer 5 of complex copper water pipe and the copper pipe 6 thickness additions of complex copper water pipe for the pipe thickness of the ccontaining connected complex copper water pipe of energy, the complex copper water pipe that is connected with pipe fitting inserts the containing space 4 at interface position, copper liner 2 setting-ins of pipe fitting are gone in the copper pipe 6 of complex copper water pipe, the copper pipe 6 that is the complex copper water pipe is enclosed within outside the copper liner 2 of pipe fitting, and the skin 5 of the polypropylene of complex copper water pipe is by skin 1 parcel of pipe fitting polypropylene.When mounted the complex copper water pipe is inserted in the containing space 4 at interface position.
Embodiment two:
Identical with embodiment one, different is can directly be connected with water valve for the ease of pipe fitting, but the other end setting-in of pipe fitting interface is gone into a brass external thread wire mouth 3, and its degree of depth that embeds pipe fitting is 12~14mm, and this brass external thread wire mouth 3 can directly be connected with water tap, valve.
