Abstract
The utility model relates to a working medium conveying hose designed specially for the air-conditioning facilities with non-fluorine refrigerant, which is characterized in that the hose has a four-layer structure, being a nylon alloy layer, an inner hose layer, a fiber reinforced layer and an outer hose layer from inner to outer. The hose has the advantages of permeation resistance, thermal aging resistance, hot water resistance, moisture permeation tolerance, oil resistance, good pliability and so on.
Description
Technical field
The utility model relates to the air conditioning hose of transferring working medium.
Background technique
The employed flexible pipes of chiller plant such as existing air-conditioning mostly are the lower three-decker of compatibility, and its performance satisfies working medium such as carrying fluorine Lyons.In order to protect atmospheric ozone layer, now vigorously promoted the use floride-free working medium substituted freon etc. as refrigeration working medium, as refrigerant R134a etc.Because the refrigerant R134a molecular diameter is little, therefore easy to leak must provide high-quality air conditioning hose.
Summary of the invention
The purpose of this utility model is exactly that a kind of floride-free refrigeration air-conditioner flexible pipe that is mainly used in refrigerant R134a will be provided.
For this reason and the tube wall of floride-free refrigeration air-conditioner flexible pipe of design is a four-layer structure, from inside to outside, be followed successively by nylon alloy layer, interior sebific duct layer, fiber-reinforced layer and outer sebific duct layer.
This flexible pipe has anti-infiltration, heat-resistingization, hot water resistance, anti-water vapor transmission, oil resistant and the good characteristics of ductility, is fit to use the air-conditioning equipment configuration of floride-free refrigeration working mediums such as refrigerant R134a.
Description of drawings
Fig. 1 is the floride-free refrigeration of a utility model hose construction schematic representation.
Embodiment
As shown in Figure 1, floride-free refrigeration flexible pipe tube wall from the inside to surface is divided into four layers, promptly by host polymer nylon 6, inferior polymer nylon 11, nylon 12, improved polyalkene, with the nylon alloy layer 1 of compatibilizer mixed coal refining; The interior sebific duct layer of making by synthetic rubber such as butyl rubbers 2; Fiber-reinforced layer 3 that is entwined by cellulose ester etc. and the outer sebific duct layer 4 that adopts ethylene propylene diene rubber etc. to make.
Claims (1)
1, floride-free refrigeration air-conditioner flexible pipe, the tube wall that it is characterized in that said flexible pipe is a four-layer structure, from inside to outside, is followed successively by nylon alloy layer, interior sebific duct layer, fiber-reinforced layer and outer sebific duct layer.
