这种电控阀是一种新型的通过电来调节流量与压力的比例阀。它的工作很象伺服机构,但大大地进行了简化:将反馈放在阀的内部。这种电控阀的一个特点是,具有伺服装置的性能,但没有伺服装置。它工作起来很象伺服装置,精确地跟踪着一个输入信号来调节输出——压力或流量。这种阀就这样工作而无需外部反馈,因此取消了伺服装置设计中的最复杂的也是最易出毛病的那部份结构。 这种新型比例流量控制阀所以能具有这种性能的一个关键,就是能实现压力补偿,即阀可以随着输入压力的变化而自动调整。伺服阀基本上是不能进行压力补偿的。它是按照遥控
This electric control valve is a new type of proportional valve that regulates flow and pressure by electricity. It works much like a servomechanism, but greatly simplifies: putting feedback inside the valve. One of the features of this electronically controlled valve is the performance of a servomechanism, but no servos. It works much like a servo, precisely tracking an input signal to regulate output - pressure or flow. The valve thus works without external feedback, thus eliminating the most complicated and fault-prone part of the servo design. One of the keys to this new proportional flow control valve is its ability to compensate for pressure, which automatically adjusts the valve as the input pressure changes. Servo valve basically can not be pressure compensation. It is according to the remote control
