Technical Field

Background
The refrigerant is an indispensable substance in modern society, and different kinds of refrigerants are filled in refrigerating equipment such as air conditioners, refrigerators and the like.
Most of refrigerants (freons) have the characteristics of low boiling point and strong penetrability, so that the sealing of pipelines is not facilitated; particularly, when the temperature is lower than-60 ℃, all rubber materials can lose efficacy and do not have a sealing effect; therefore, copper pipes are mostly adopted in pipelines for conveying the refrigerant (by utilizing the characteristics of low hardness and strong ductility), and the copper pipes are connected after being flared by a flaring tool at the joint. However, the copper pipe is poor in flexibility and needs to be constructed on site, and after the copper pipe is flared, the wall thickness of the copper pipe is thinned, so that the copper pipe cannot be repeatedly disassembled for many times, and the pipeline is greatly limited.
The metal hose has good antagonism to the infiltration of refrigerant and has fine low temperature resistance, but the vast majority of metal hose uses stainless steel material to make, involves dissimilar welding when welding with copper pipe or copper joint, has higher requirement to welding equipment, is unfavorable for the manufacturing of metal hose assembly. Therefore, the method is always an industrial problem in the aspects of pipeline type selection and sealing of low-temperature refrigeration equipment. Thus, we propose a hose connector.
