The structure, performance and application of the control valve The control valve is a commonly used regulating mechanism in industrial production. Its role is to change the opening of the valve through the actuator according to the size and direction of the control signal sent by the regulator to achieve the function of regulating fluid flow, so as to control the adjusted parameters in the production process within the range required by the process, So as to realize the automation of the production process. The control valve is a very important and indispensable part of the automatic control system. The correct selection and use of the control valve is directly related to the control quality of the entire automatic control system, and directly affects the quality of production products. However, many of the abnormalities of the automatic control system are caused by the improper selection of the regulating valve. Therefore, every automation control technician must attach great importance to how to correctly select the appropriate regulating valve. The problems reflected by the regulating valve mostly focus on the working characteristics and structural parameters, nominal diameter and flow characteristics of the regulating valve. Among these parameters, the flow capacity is more important. Its size directly reflects the capacity of the regulating valve. It is the main parameter in the design and selection. Therefore, the selection of regulating valve is mainly based on the above factors. According to the experience of regulating valve selection in work, briefly introduce the principles and precautions of regulating valve selection.

Therefore, whoever needs to use such parts as the electric butterfly valve should carefully understand the problems in this regard, so as to solve all kinds of problems in the shortest time during the whole use process and avoid many problems. When learning and understanding, you can master it carefully. Relevant information Grasp several key points for the selection of electric control valves Talk about the matters of electric control valves (I) The installation guide of electric control valves is worth seeing if you understand the working principle of pneumatic control valves and what are the culprits that lead to the untight closing of pneumatic butterfly valves
