气动调节阀在自动调节系统中是一个非常重要的环节.人们常把调节阀比喻为生产过程自动化的“手足”.由于生产过程的调节对象要求调节阀具有各种各样的特性,以满足生产工艺的需要.在调节阀的附属装置中,最主要、最实用的是阀门定位器. 现场使用阀门定位器的种类非常繁多,有气动阀门定位器、电汽阀门定位器,有配薄膜执行机构的阀门定位器,有配活塞执行机构的阀门定位器,有力平衡式
Pneumatic control valve in the automatic adjustment system is a very important part.People often control valve analogy for the production process automation “hands and feet ” .As the regulation of the production process requires a variety of features valve to To meet the needs of the production process.In the control valve attached to the device, the most important and most practical is the valve positioner. Field use of the valve positioner is very diverse, pneumatic valve positioner, electric steam valve positioner, with film Actuator valve positioner, valve positioner with piston actuator, powerful balanced
