Huizheng Automatic Control Valve Group Co., Ltd. is a well-known company that provides products and services for control valve in China. We professional manufacture regulating valves ,Control valve importance as follows:
Regulating valve is used to regulate the flow of the operating variable, so it is called the regulating valve.
1. regulating valve is a throttling device, which is a moving part. Compared with the detection element, transmitter and controller, the regulating valve needs to constantly change the flow area of the throttling part during the control process to change the manipulated variable to adapt to the load. Changes in operating conditions. Therefore, higher requirements are put forward on the sealing, pressure resistance, and corrosion of the valve components of the regulating valve. For example, sealing will increase the friction of the regulating valve, increase the dead zone of the regulating valve, and cause the quality of the control system to deteriorate.
2 The moving parts of the regulating valve are the main cause of running, emitting, dripping and leaking. It not only causes waste of resources or materials, but also pollutes the environment and causes accidents.
The contact medium of the control valve material may be different from the contact medium of the detection element. Therefore, higher requirements are put forward for the corrosion resistance, strength, and rigidity of the control valve.
3. The throttling of the regulating valve causes energy to be consumed inside the valve. Therefore, a reasonable choice should be made between reducing energy consumption, reducing pressure loss of the regulating valve, and ensuring better control quality.
4. The regulating valve throttling the fluid also causes noise. For example, when the outlet pressure of the regulating valve is lower than the vapor pressure of the liquid,it will be lead to flashing occurs; when the pressure downstream of the regulating valve is higher than the vapor pressure of the liquid, it causes cavitation. . The noise caused by the regulating valve is related to the design of the regulating valve flow path, operating pressure, and the characteristics of the controlled medium. Therefore, reducing noise and reducing pressure loss put forward higher requirements on regulating valves.。
5. The adaptability of the regulating valve is strong. It is installed in a variety of different production processes. The high temperature, low temperature, high pressure, large flow, small flow and other operating conditions of the production process require the regulating valve to have various functions, and the regulating valve can adapt to the requirements of different applications.
6. detection components, transmitters, controllers, etc. are developing rapidly, and more manpower and material resources are invested. Relatively speaking, it is generally considered that the control valve structure is simple to adjust, and the control valve is very important. Therefore, the manpower and material resources for the research and development of the control valve are relatively insufficient
