Intelligent control valve and standardization has been mentioned on the agenda, intelligent mainly the use of intelligent valve Locator, intelligent performance in the following aspects.
(1) control valve self-diagnosis, running state of remote communication and other intelligent functions, so that the control valve management gate valve diagnosis becomes easy, but also reduce the maintenance personnel skills requirements. (2) Intelligent valve Controller.
Intelligent Valve Locator has all the functions of valve locator, at the same time can change the dynamic and static characteristics of the trap valve, improve the control accuracy of the control valve, therefore, intelligent valve Locator will become an important control valve auxiliary equipment for a period of time in the future is widely used. (3) Digital communication. Digital communication will be widely used in the control valve plug valve, based on HART communication protocol, some control valve valve locator will input signal and valve position signal in the same transmission line to achieve, based on fieldbus technology, control valve and valve locator, PID control function Gate valve so that the control function in the field level to achieve, so that the danger dispersion,
Make control more timely and faster. (4) Reduce product types and simplify production processes. The use of Intelligent valve Locator can not only easily change the flow characteristics of the control valve can also improve the control cut-off valve system quality. Therefore, the requirements for the flow characteristics of the control valve can be simplified and standardized (for example, only the production line characteristic control valve). With the Intelligent function module to achieve the matching with the characteristics of the controlled object, so that the type and variety of control valve products greatly reduced, so that the control valve manufacturing check valve process has been simplified. In order to reduce the variety of control valves, domestic manufacturers also produce full-function control valves, these intelligent methods will continue to improve, and in the production and market to stand the test and recognition.
