摘　　要：本文以公司一款拉伸液压机液压系统的背压回路为研究对象,系统分析背压回路所参与的各种工况,针对生产中出现的误动作现象,从采购的标准溢流阀阀体结构入手,借助背压回路循环动作研究的知识经验,创新思维模式,对溢流阀标准阀体结构进行新的创新。建立起一套拉伸液压机的新型回路,在实践中验证了该回路的合理性。Taking the back pressure loop of hydraulic system for one kind of drawing hydraulic press as a research object in the text, all kinds of working condition involved of back pressure loop have been analyzed. Aiming at the phenomenon of false action in production, the structure of standard relief valve body has been innovated by use of knowledge ＆ experience of back pressure loop circular motion and innovative thinking mode. The new type of loop has been established for drawing hydraulic press. The rationality of the loop has been verified in practice.
