Description
Technical field
The utility model relates to a kind of rubber pipe, particularly relates to the refrigeration sebific duct of the multiple refrigeration agent of a kind of compatibility for the chiller plant such as air-conditioning, refrigerator.
Background technique
Along with manufacturing fast developments such as automobiles, the application of refrigeration and air-conditioning system is flourishing as never before, in recent years along with science and technology constantly progress, environmental pollution has become the most thorny issue instantly with greenhouse effect, the environmental protection refrigerant of the industrial refrigeration system such as automobile selects and the protection of conventional chiller becomes at present the most fast, most effective measures; Because of piping material, restriction is very difficult completely not alternative by environmental protection refrigerant (as R404A, R410A and R134A) on an equal basis in the amine conventional refrigerants application in the industry such as R12, R22, R502 chlorine fluorine class refrigeration agent and R717, R718.The general refrigeration agent infiltration capacity of existing common sebific duct pipeline is comparatively large, causes a large amount of refrigeration agent to be discharged in air and causes huge damage to health and atmospheric ozone layer.Simultaneously albronze pipeline in working order under owing to producing vibration in compressor operating, noise can cause resonance to cause the lost of life of whole refrigeration system in narrow working space.The infiltration of refrigeration agent also can have certain corrosive effect to pipeline.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of good airproof performance, noise is low, the life-span is long, the refrigeration sebific duct of the simple compatible multiple refrigeration agent of structure.
The refrigeration sebific duct of the multiple refrigeration agent of a kind of compatibility of the utility model, comprise five-layer structure, ecto-entad is followed successively by ethylene-propylene-diene monomer glue-line, synthetic fiber layer, mesosphere, barrier layer and chlorosulfonated polyethylene layer, described barrier layer adopts modified polyamide material, described intermediate layer material selects chlorosulfonated polyethylene, described synthetic fiber layer is the reticular structure be woven into after high strength synthetic fibre twisting, and described cancellated surface attachment has bonding glue-line.
The refrigeration sebific duct of the multiple refrigeration agent of a kind of compatibility of the utility model, wherein said chlorosulfonated polyethylene layer adopts chlorosulfonated polyethylene rubber to form macromolecular elastomer.
The refrigeration sebific duct difference from prior art of the multiple refrigeration agent of a kind of compatibility of the utility model is that the refrigeration sebific duct of the multiple refrigeration agent of a kind of compatibility of the utility model forms macromolecular elastomer by the chlorosulfonated polyethylene rubber of resistance to petroleum based lubricants, resistance to synthetic lubricant fluid and excellent chemical resistance in inner side, has good tolerance to conventional refrigerants (as: R12, R22, R502, R717, R718) and environmental protection refrigerant (as: R404A, R410A and R134a).Can ensure that the tightness of product is under-30 DEG C ~ 125 DEG C ambient temperatures, ne-leakage under the pressure condition of 5.0MPa.The Ethylene Propylene Terpolymer macromolecular material that outermost ethylene-propylene-diene monomer glue-line adopts du pont company to manufacture, there is high temperature resistant (Long-term service temperature 125 DEG C, Maximum operating temperature can reach 150 DEG C), (ozone concentration is 50ppm to best ozone resistance, 40 DEG C of temperature are unchanged after lower 1000 hours), Weather-resistant, resistance to electromagnetic radiation, heat-resistingly (to soak after 15 months in 125 DEG C of superheated waters, mechanical property change is very little, specific volumetric dilatation only 0.3%) etc. excellent performance.Synthetic fiber layer has carried out dipping process after adopting high strength synthetic fibre twisting, fiber and neighboring layers good bond, make sebific duct bursting pressure for reaching more than 20.0MPa, it is the working pressure (cooling machine set Maximum operating pressure 3.15MPa) of 6 times, and the bursting pressure of safe design sebific duct is 4 times of working pressures usually, the utility model is safer in use.The barrier layer gap that modified polyamide is formed is little, obvious to the refrigeration agent barriering effect of general particle, greatly can reduce the permeability of refrigeration agent, extend the service time of refrigeration agent, reduce the damage to ozonosphere.Each layer is connected closely with between synthetic fiber layer and barrier layer, compounding ingredient self expansion effect, effectively can vibrate by absorption system, reduce noise during work.
Be described further below in conjunction with the refrigeration sebific duct of accompanying drawing to the multiple refrigeration agent of a kind of compatibility of the present utility model.
Accompanying drawing explanation
Fig. 1 is the schematic cross-section of the refrigeration sebific duct of the multiple refrigeration agent of a kind of compatibility of the utility model.
Embodiment
As shown in Figure 1, the refrigeration sebific duct of the multiple refrigeration agent of a kind of compatibility of the utility model comprises five-layer structure, and ecto-entad is followed successively by ethylene-propylene-diene monomer glue-line 1, synthetic fiber layer 2, mesosphere 3, barrier layer 4 and chlorosulfonated polyethylene layer 5.Chlorosulfonated polyethylene layer 5 adopts chlorosulfonated polyethylene rubber to form the macromolecular elastomer of resistance to petroleum based lubricants, resistance to synthetic lubricant fluid and excellent chemical resistance, ensure that body firmly maintains certain toughness simultaneously, simultaneously can fine compatible various refrigeration agent.The modified polyamide material that barrier layer 4 adopts du pont company to produce.Synthetic fiber layer 2 is provided with between mesosphere 3 and ethylene-propylene-diene monomer glue-line 1.The material selection butyl rubber in mesosphere 3 or chlorosulfonated polyethylene.Synthetic fiber layer 2 is the reticular structure that is woven into after high strength synthetic fibre twisting, and through gum dipping process processing, makes it more easily to be combined with each Rotating fields, and formation is tight and have the structure of toughness.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
