Abstract
The utility model provides an integral type heat preservation metal hose, includes a heat -resisting PE pipe, and the cover is equipped with an insulating tube on heat -resisting PE pipe's the outer wall, and the insulating tube comprises crosslinked polyethylene heat preservation cotton, and the outside of insulating tube is encircleed and is provided with the band. The theory of operation is: heat -resisting PE pipe's (being the PERT pipe) pliability is good, can be used to the air conditioner, in the system such as warm up, can linger and the mistake when the lintel, can easily turn and not influence rivers, it is less that its pipe wall resistance almost is 0, entire system's hydraulic losses. Heat -resisting PE pipe can effectively reduce cold thermal transmission after setting up the insulating tube outward, reduces the producing probability of comdenstion water. It is cotton that the insulating tube adopts crosslinked polyethylene to keep warm, and coefficient of heat conductivity 0.029wMK is lower than rubber and plastic heat preservation coefficient of heat conductivity, can reduce the thickness of insulating tube, is fit for the engineering needs.
Description
Technical field:
The utility model relates to mechanical field, particularly relates to pipeline, particularly a kind of integral heat preservation flexible pipe.
Background technique:
The installation of water system is included in central air-conditioning system.Existing central air-conditioner water pipe (bypass duct) material is mainly two kinds: PPR and Coating Steel Pipe, and insulation adopts rubber plastic pipe insulation.Rubber plastic pipe has various caliber available, when workmen installs can directly by heat-insulating cover on pipeline.Because Coating Steel Pipe and PPR pipe road to turn round or reducing place needs to arrange elbow or hot melt each, the difficulty of therefore installing thermal insulation pipe at places such as joint, reducing, valve members is large, and needed time is longer.
Summary of the invention:
The purpose of this utility model is to provide a kind of integral heat preservation flexible pipe, and described this integral heat preservation flexible pipe will solve the technical problem that in prior art, in central air-conditioning system, water pipe insulation difficulty is large.
This integral heat preservation flexible pipe of the present utility model, comprise a heat-resisting polyethylene tube, wherein, the outer wall of described heat-resisting polyethylene tube is arranged with a thermal insulation pipe, described thermal insulation pipe is made up of crosslinked polyethylene heat-preservation cotton, and the outside of thermal insulation pipe is surrounded with band.
Working principle of the present utility model is: the pliability of heat-resisting polyethylene tube (i.e. PERT pipe) is good, can be used for, in the system such as air-conditioning, floor heating, can lingering and mistake when lintel, easily can turn and not affect current, its tube wall resistance is almost 0, and the hydraulic loss of whole system is less.After thermal insulation pipe is set outside heat-resisting polyethylene tube, effectively can reduce the transmission of cold and hot amount, reduce the generation probability of condensed water.Thermal insulation pipe adopts crosslinked polyethylene heat-preservation cotton, lower than rubber and plastic insulation thermal conductivity, can reduce the thickness of thermal insulation pipe, be applicable to requirement of engineering.
The utility model is compared with prior art, and its effect is actively with obvious.The utility model is at the sheathed thermal insulation pipe in the outside of flexible pipe, and utilize band around fixing, pliability is good, can be used for, in the system such as air-conditioning, floor heating, can lingering and mistake when lintel, and easily can turn and not affect current, the hydraulic loss of whole system is less.Thermal insulation pipe effectively can reduce the transmission of cold and hot amount, reduces the generation probability of condensed water.Thermal insulation pipe adopts crosslinked polyethylene heat-preservation cotton, lower than rubber and plastic insulation thermal conductivity, can reduce the thickness of thermal insulation pipe, be applicable to requirement of engineering.Pipeline and insulation have been prefabricated in the factory, and dispatch from the factory one-body molded.Decrease the step be incubated in construction and installation process.Effectively decrease operation in man-hour.And shaping owing to being prefabricated in the factory, so risk is little compared with in-site installation.Be conducive to the control of engineering management, risk management, quality control.

Fig. 1 is the schematic diagram of integral heat preservation flexible pipe of the present utility model.
Fig. 2 is the schematic diagram of the radial cross section of integral heat preservation flexible pipe of the present utility model.
Embodiment:
Embodiment 1:
As depicted in figs. 1 and 2, integral heat preservation flexible pipe of the present utility model, comprise a heat-resisting polyethylene tube 1, wherein, the outer wall of described heat-resisting polyethylene tube 1 is arranged with a thermal insulation pipe 2, described thermal insulation pipe 2 is made up of crosslinked polyethylene heat-preservation cotton, and the outside of thermal insulation pipe 2 is surrounded with band 3.
The working principle of the present embodiment is: heat-resisting polyethylene tube 1(and PERT manages) pliability good, can be used for, in the system such as air-conditioning, floor heating, can lingering and mistake when lintel, easily can turn and not affect current, its tube wall resistance is almost 0, and the hydraulic loss of whole system is less.After thermal insulation pipe 2 is set outside heat-resisting polyethylene tube 1, effectively can reduce the transmission of cold and hot amount, reduce the generation probability of condensed water.Thermal insulation pipe 2 adopts crosslinked polyethylene heat-preservation cotton, lower than rubber and plastic insulation thermal conductivity, can reduce the thickness of thermal insulation pipe 2, be applicable to requirement of engineering.
