Model utility content
The purpose of this utility model is to provide a kind of heat-insulation and heat-preservation lining to mould the pipe-line system of PE-RT II Al-alloy pipe and formation thereof, solves existing plastics-lined aluminium alloy pipe heat insulation and preservation effect not good, and the higher problem of cost of production.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Heat-insulation and heat-preservation lining is moulded PE-RT II Al-alloy pipe, comprises aluminum alloy outer tube, and in be lining in the plastic pipe on aluminum alloy outer tube wall, between described aluminum alloy outer tube and plastic pipe, be also provided with insulating.
Further, described insulating is polyurethane insulating.Certainly also can adopt other to there is the thermal insulation layer of good heat insulation and preservation effect.
By heat-insulation and heat-preservation lining, mould the pipe-line system that PE-RT II Al-alloy pipe forms, comprise that heat-insulation and heat-preservation lining moulds PE-RT II Al-alloy pipe, and mould with heat-insulation and heat-preservation lining the pipe fitting that PE-RT II Al-alloy pipe is connected; Described heat-insulation and heat-preservation lining is moulded PE-RT II Al-alloy pipe and is comprised aluminum alloy outer tube, and in be lining in the plastic pipe on aluminum alloy outer tube wall, between described aluminum alloy outer tube and plastic pipe, be also provided with insulating.
Further, described pipe fitting comprises the plastic fastening being connected with plastic pipe, is arranged at the outer field insulating of plastic fastening, and is arranged at the Aluminum Alloy Tube protecting jacket outside insulating.Described Aluminum Alloy Tube protecting jacket is fastened and is formed by the first fastener and the second fastener, and be the pipe fitting protective sleeves such as elbow, direct, threeway.
Again further, described insulating is polyurethane insulating.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) the utility model is also provided with insulating between aluminum alloy outer tube and plastic pipe, can effectively improve the heat insulation and preservation effect of plastics-lined aluminium alloy pipe, without in Al-alloy pipe outside, one layer of heat preservation layer is installed again after installing plastics-lined aluminium alloy pipe as prior art, operation is trouble quite, has increased cost simultaneously; Plastics-lined aluminium alloy pipe of the present utility model just has excellent heat insulation and preservation effect when producing, and the beautiful outward appearance of plastics-lined aluminium alloy pipe is unaffected.
(2) Aluminum Alloy Tube protecting jacket of the present utility model is comprised of the first fastener and the second fastener, and it is simple in structure, easy for installation, time saving and energy saving, and can guarantee the rigidity of pipe fitting and the conformity of pipe-line system material.
(3) the utility model is simple in structure, easy to operate, safe and reliable, with low cost, is suitable for promoting the use of.
