Abstract

Based on mechanical phenomena between two fixed magnetic, when the distance is short, the electromagnetic force are linear,therefore,we can make full use of the characters and make it to be permanent magnetic spring replacing the mechanical spring in hydraulic relief valves. Through the use of the Rare-earth magnetic springs in relief valves, we find it is more sensitive to load. Besides these, the rare-earth magnetic springs have a long life and high temperature resistance without failure by fatigue. So the study and design of permanent magnetic spring type relief valve have large application and research value.
