Abstract
The utility model provides a household air-conditioner refrigerant hose, which comprises an inner nylon shielding layer (1), a middle rubber layer (3), a braided strengthened layer (4) and an outer rubber layer (5) from inside to outside. The household air-conditioner refrigerant hose is characterized in that an inner anti-seepage layer (2) is added between the inner nylon shielding layer (1) and the middle rubber layer (3). Due to the anti-seepage layer structure additionally arranged between the inner nylon shielding layer and the middle rubber layer of the hose, the hose can meet requirements of household air-condition refrigerant to permeability. Further, the household air-conditioner refrigerant hose is better in flexibility and shock absorption, and can effectively reduce pipeline damage caused by vibration of an air-conditioner compressor.
Description
Technical field
A kind of air conditioner coolant flexible pipe that the utility model relates to, particularly a kind of domestic air conditioning refrigerant flexible pipe that is applicable to refrigerant R22 and R410a.
Background technique
Refrigerant pipe in the existing domestic air conditioning generally adopts copper pipe, has the cost height, need increase pipeline elasticity and cause large usage quantity by special knot hook, transmits shortcomings such as noise easily; Existing car air conditioner then generally adopts compound refrigerant flexible pipe, reducing cost, reduce the rigidity vibration and reduce the noise aspect and have clear superiority, but car air conditioner refrigerant commonly used is R12 (boiling point :-29.8 ℃) and R134A (boiling point :-26.3 ℃), and domestic air conditioning refrigerant commonly used is R22 (boiling point :-40.8 ℃), (R410A is 50/50 mixture of R32 and R125 to R410A, R32 boiling point :-51.7 ℃, R125 boiling point :-48.5 ℃), by contrast, the refrigerant permeability of domestic air conditioning is very strong, boiling point is lower, working pressure higher (working pressure of R22 is 1.6 times of R12).Directly adopt automotive air conditioning hose if solve the shortcoming of copper pipe, its anti-permeability performance, withstand voltage properties etc. all can not satisfy the requirement of domestic air conditioning refrigerant.
The model utility content
The purpose of this utility model is to consider the problems referred to above and provides a kind of and can reach the domestic air conditioning refrigerant flexible pipe that the domestic air conditioning refrigerant requires the every performance index of flexible pipe.
The technical solution of the utility model is: a kind of domestic air conditioning refrigerant flexible pipe, and nylon screen layer, mesoglea, braiding enhancement layer and outer glue-line in comprising from inside to outside, its characteristics are to set up interior impermeable layer between interior nylon screen layer and mesoglea.
Impermeable layer is made by the EVOH composite material in above-mentioned.
The EVOH material surface of impermeable layer scribbles the water-fast modified PVA emulsion of one deck in above-mentioned.
The nylon screen layer is made by the nylon-6 material in above-mentioned.
Above-mentioned mesoglea is made by ethylene propylene diene rubber, neoprene, brombutyl or chlorinated scoline material.
Above-mentioned braiding enhancement layer is by glass fibre, and polyester fibre or aromatic nylon lamination coating are made.
Above-mentioned outer glue-line is made by EPDM, neoprene CR, butyl rubber IIR, brombutyl BIIRO, chlorinated scoline CIIR, chlorinated polyethylene rubber CM, chlorosulfonated polyethylene rubber CSM or silicone rubber.
The structure of impermeable layer in the utility model owing to adopt is set up between the interior nylon screen layer of flexible pipe and mesoglea, thereby satisfy of the permeability requirement of domestic air conditioning refrigerant to flexible pipe, and this novel air conditioner coolant flexible pipe, pliability and absorbing are better, can effectively alleviate the infringement that air conditioner compressed machine vibration causes pipeline.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Following structure drawings and Examples are further described the utility model.
As shown in Figure 1, the utility model domestic air conditioning refrigerant flexible pipe, nylon screen layer 1, interior impermeable layer 2, mesoglea 3, braiding enhancement layer 4 and outer glue-line 5 in comprising from inside to outside, impermeable layer 2 in having additional between above-mentioned interior nylon screen layer 1 and the mesoglea 3.
In the present embodiment, above-mentioned interior impermeable layer 2 is made by the EVOH composite material.The EVOH material surface of impermeable layer 2 can scribble the water-fast modified PVA emulsion of one deck in above-mentioned, and cold-resistant matchmaker of PVA material and air-conditioning hydraulic oil swelling are low to the flow resistance of refrigerant, and have good permeability resistance.Nylon screen layer 1 is made by the nylon-6 material in above-mentioned.Above-mentioned mesoglea 3 is made by ethylene propylene diene rubber, neoprene, brombutyl or chlorinated scoline material.The effect of above-mentioned braiding enhancement layer 4 is that to flexible pipe provides strength support promptly as the framework material of flexible pipe, the restriction flexible pipe is in radial and axial distortion, and it is by glass fibre, and polyester fibre or aromatic nylon lamination coating are made.Above-mentioned outer glue-line 5 directly contacts with atmosphere environment, requirement has characteristics such as good weather-resistant and ozone aging, is made by EPDM, neoprene CR, butyl rubber IIR, brombutyl BIIRO, chlorinated scoline CIIR, chlorinated polyethylene rubber CM, chlorosulfonated polyethylene rubber CSM or silicone rubber.
