Do you know the structure principle of regulating valve？

        Regulating valve, process control in industrial automation field, byadjusting the control unit outputs the control signal, the finalcontrol element with the power to change the media flow,pressure, temperature, level and other parameters. Generally by the actuator and valve components. If press trip characteristics,control valve can be divided into linear and angular travel itinerary;by its executive agencies use the power, according to their functions and features into linear characteristics, such as the percentage of properties and characteristics of the three parabolic. Control valve for air, water, steam, all kinds of corrosive media, mud, oil and other media.

      The structure principle

      Self pressure regulating valve because no other external energy sources such as power supply, gas supply, relying on the media's own energy to drive, energy saving and environmental protection, convenient use, installation and after setting the pressure value can be input automatically, so the requirement forthe control accuracy is not high, the lack of power, gas source of the occasion, the use of more and more widely. But in the use process, must pay attention to the special selection, otherwise easily lead to accidents. In the use process, must pay attention to the use of selection and installation of the environment, therefore,a detailed understanding of the working principle and the structureof self pressure regulating valve is very important.
