广泛地采用比例阀是宝钢钢管厂液压设备的特色。使用比例电磁铁令换向阀不仅有换向,且有比例控制的功能。若配合使用压力补偿阀,则对流量控制不仅不受油粘度(油温)变化的影响,亦不受压力(负载)变化的影响,起流量调节阀作用。可以按需要调整启动(制动)的加(减)速度,实现软启(制)动,避免冲击。研制比例阀时,信号控制功能尽量让电子装置去完成,功率放大功能让液压元件去执行。
Widely used proportional valve is Baosteel Steel Works hydraulic equipment features. The use of proportional solenoid valve not only to change direction, and a proportional control function. If used in conjunction with the pressure compensation valve, the flow control is not only not affected by changes in oil viscosity (oil temperature), nor by pressure (load) changes, the role of flow control valve. Can be adjusted according to need (brake) increase (decrease) speed, to achieve soft start (system) move, to avoid the impact. Development of proportional valve, the signal control function as far as possible to complete the electronic device, the power amplifier to hydraulic components to perform.
