Document Type and Number:
WIPO Patent Application WO/2021/035908
Kind Code:
A1
Abstract:
A soft and hard pipe connecting system suitable for high pressure, comprising: a soft pipe formed by connecting a core pipe (1) and a corrugated pipe (2), wherein the outside of the soft pipe is provided with a coated rubber layer (4); a hard pipe (5); a transition joint (7) connecting the soft pipe and the hard pipe; and a buckling sleeve (8) that is buckled and pressed on the outside of the soft pipe and the transition joint. The present invention can greatly improve the sealing performance between the soft pipe and the hard pipe, and solves the problems that a connection position between the soft pipe and the hard pipe cannot bear pressure, and cannot resist a high temperature and a low temperature, thereby being capable of being used under the working conditions of the high temperature, the low temperature, and the high pressure, and further being capable of being used in an air conditioner pipeline of a new energy automobile.
