Technical Field
The invention relates to the technical field of regulating valves, in particular to an intelligent electric corrugated pipe regulating valve.
Background
In the automatic control of modern plants, control valves play a very important role, and the production of these plants depends on the correct distribution and control of the flowing medium. These controls, whether energy exchange, pressure reduction or simple vessel charging, require some final control element to accomplish; the regulating valve acts as a variable resistance in the conduit. It changes the turbulence of the process fluid or provides a pressure drop in laminar flow conditions, which is caused by changing the valve resistance or "friction". This pressure reduction process is commonly referred to as "throttling". For gases, which are close to isothermal adiabatic conditions, the deviation depends on the non-ideality of the gas (joule-thomson effect). In the case of liquids, the pressure is then dissipated by turbulent or viscous friction, both of which convert the pressure into heat energy, resulting in a slight increase in temperature.
