濟南裝載機調節閥在過程控制中有什么作用？

濟南裝載機調節閥在過程控制中的作用是眾所周知的，在許多控制過程中要求調節閥在故障時處于某一個位置，以保護工藝過程不出現事故，這就要求調節閥在設計上實現安全的三斷（斷氣、斷電、短信號）保護措施。對于電動調節閥來說，比較簡單，斷信號時，可以根據控制模塊的設定而停留在全開、全關、保持中的任一位置，而斷電時，自然停留在故障位置，或帶有復位裝置的電動執行器也可將閥位運行到全開或全關。 
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.
