In the automatic control of modern factories, regulating valves play a very important role, and the consumption of these factories depends on the correct distribution and control of the active medium. These manipulations, whether energy communication, pressure drop or simple container feeding, require some final control element to complete. The regulating valve acts as a variable resistance in the pipeline.
It modifies the turbulence of the process fluid or provides a pressure drop in the case of laminar flow. The pressure drop is caused by changing the valve resistance or conflict. This pressure reduction process is generally referred to as throttling. Regarding the gas, it is close to the isothermal adiabatic state, and the tendency depends on the non-ideal level of the gas (Joule-Thomson effect). In the case of liquids, pressure is consumed by turbulence or viscous conflict, both of which convert pressure into heat, causing a slight increase in temperature.
The common control loop consists of three primary parts, part of which is the sensitive element, which is generally a transmitter. It is a device that can be used to measure the parameters of the process to be adjusted, such as pressure, liquid level or temperature. The output of the transmitter is sent to the regulating instrument, the regulator, which must measure the tendency between the given value or expected value and the practical value of the process parameter, and send the correction signal one by one to the final control element, the regulating valve.
The valve changes the flow of the fluid, so that the process parameters reached the desired value. Control valve attributed to the control valve series, the primary role is to adjust the medium pressure, flow, temperature and other parameters, is the process loop in the final control components. The regulating valve is also called the control valve. After receiving the control signal output by the regulating control unit, the fluid flow is changed by means of power operation.
Regulating valve by the general actuator and valve composition. If according to the power used by the actuator, the control valve can be divided into three types: pneumatic control valve, electric control valve and hydraulic control valve. In addition, according to its function and characteristics, linear characteristics, equal percentage characteristics and parabolic characteristics.
