摘要
针对系统中的普通低压直动式溢流阀的静特性,提出了阀口动压反馈低压直动式溢流阀的新结构,改善了溢流压力随流量变化的特性;且当通过流量在大范围变化时,减小了溢流阀溢流压力的变化比率。
According to the static characteristic of common low-pressure spillway valve in the hydraulic system,a new structure of the valve port dynamic pressure feed-back low-pressure spillway valve was put forward,which improves the characteristic of spillway pressure changing with flow,and decreases the setting pressure deviation when flow changes in low-pressure range.
