 气动阀门开关的动作速度

原文:
       气动阀门开关动作速度可以调整,结构简单,易维护,动作过程中因气体本身的缓冲特性,不易因卡住而损坏,但必须有气源,且其控制系统也比电动阀门复杂。气动阀门响应灵敏,安全可靠,很多对控制要求高的厂专为气动仪表控制元件设置压缩空气站。电动的就是要电。电动阀门和气动阀门的本质区别在于使用不同的驱动装置,也就是执行机构,而调节阀本身没有什么区别。

       配合不同的执行机构主要是工况要求,如化工等要求防爆的场合,使用最多的是气动阀门,因为安全性要求高,而且价格便宜,配合智能定位器可以上总线,控制方式也简单。电动阀门执行机构动力源为电源,如果线路板或电机出现故障容易出现火花,所以一般应用在环境要求不高和没有危险的场合。气动阀门执行机构动力源为气源,气源来源于空压机,采用定位器将电控信号转换成气动控制信号,驱动气动执行机构进行阀位调节。气动阀门开关的动作速度。

Pneumatic valve switch operation speed

Original:
       Pneumatic valve switching speed can be adjusted , simple structure , easy maintenance, the course of action due to buffering characteristics of the gas itself is not easy to get stuck because of damage , but there must be gas source , and its control system is also more complex than an electric valve. Pneumatic valves sensitive response , safe, reliable , and many high requirements for the control of plant instrumentation designed for pneumatic control components set air station . Electric power is to . The essential difference between the electric valves and pneumatic valves that use a different drive means , the actuator is , the valve itself, there is no difference.

       With different actuators are mainly working conditions , such as chemical and other requirements of proof of occasions , the most used are pneumatic valves, because of security requirements, and cheap, with smart positioner can on the bus , the control mode is also simple. Electric valve actuator power source for the power , if the circuit board or motor failure prone spark , it is generally used in less demanding environments and there is no danger of the occasion . Pneumatic valve actuators power source for the gas supply , gas supply from the compressor , using positioning converts electric signals into pneumatic control signal to drive the pneumatic actuator valve position adjustment. Pneumatic valve switch operation speed .

           Translation is for reference only . In addition, the Shanghai-line pneumatic valve plant also provides search related products : pneumatic valve, pneumatic valve , pneumatic valve, pneumatic valve, pneumatic diaphragm valve and so on. Welcome to your purchase . We will be happy to serve you. Pneumatic valve switch operation speed .
