    济南装载机调节阀在过程控制中有什么作用?
    2014-5-27 19:14:23

    济南装载机调节阀在过程控制中的作用是众所周知的,在许多控制过程中要求调节阀在故障时处于某一个位置,以保护工艺过程不出现事故,这就要求调节阀在设计上实现安全的三断(断气、断电、短信号)保护措施。对于电动调节阀来说,比较简单,断信号时,可以根据控制模块的设定而停留在全开、全关、保持中的任一位置,而断电时,自然停留在故障位置,或带有复位装置的电动执行器也可将阀位运行到全开或全关。 
    Jinan loader regulation process control valve is well known, the process requires many control valve when a fault in a position to protect the process is not an accident, which requires the design of the safety valve on the realization three broken (breathe, power, SMS number) protective measures. The electric control valve is relatively simple, the interrupt signal, the control module can be set according to the desired fully open, fully closed, remain in any one position, and when power failure to stay in the natural position, with or without there reset device electric actuator valve can also be run to the fully open or fully closed.
