Ultra-low leakage environmentally friendly refrigerant filling pipe

Abstract

The invention relates to an ultra-low leakage environment-friendly refrigerant filling pipe. The ultra-low leakage environment-friendly refrigerant filling pipe comprises a pipe body with a middle rubber layer; a nylon alloy layer is arranged inside the middle rubber layer; a fiber woven reinforced layer is arranged outside the middle rubber layer; a red or yellow or blue outer rubber layer is arranged outside the fiber woven reinforced layer. The nylon alloy layer has good gas permeability resistance and refrigerant permeability resistance, and can serve as a leakage prevention structural layer. Compared with a traditional rubber inner pipe, the leakage prevention capacity of the whole pipe can be improved, the permeability is extremely low, especially the nylon alloy layer has high molar ratio, compactness and corrosion resistance, and the nylon alloy and the middle glue are tightly attached to form a whole so as to improve the burst pressure of the flexible pipe.

Description

technical field [0001] The invention relates to the field of air conditioning and refrigeration, in particular to an ultra-low-leakage environmentally friendly refrigerant filling pipe. Background technique [0002] Regardless of whether it is a household air conditioner, a central air conditioner, or a car air conditioner, after a period of use, the leakage of the refrigerant will affect the cooling effect. It is necessary to refill the refrigerant to make the refrigeration system work and make the ambient temperature meet the temperature requirements we set. For example, it is called " The disclosed technology of "A Refrigerant Filling Device for Automobile Air Conditioning" (publication number: CN203964481U) is a technology for refilling refrigerant for vehicle air conditioners. The refrigerant filling pipe in the prior art uses a rubber hose, and the rubber hose of the refrigerant filling pipe includes an inner rubber layer, an outer rubber layer, and a fiber wire braide...

AI Technical Summary

Problems solved by technology

In the actual use of the refrigerant filling pipe with this structure, it is easy to cause the problems of refrigerant leakage and pipe burst

In addition, with the expansion of car users, the operators who perform refrigerant filling are not professional maintenance personnel. More and more ordinary car users choose to fill refrigerant by themselves. Due to the lack of professional knowledge or familiarity of ordinary car users, they often Inaccurate pipeline identification, resulting in incorrect pipeline connection, resulting in failed filling or unnecessary time wastage
