Technical Field
The invention relates to the technical field of regulating valves, in particular to a pneumatic cage type single-seat 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 the case of manual regulator valve laminar flow, 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. A common control loop comprises three main parts, the first part being a sensing element, which is usually a transmitter. It is a device that can be used to measure a process parameter being regulated, such as pressure, level or temperature. The output of the transmitter is fed to a regulating instrument, the regulator, which determines and measures the deviation between a set or desired value and the actual value of a process parameter, and sends correction signals one after the other to the final control element, the regulating valve. The valve changes the flow of the fluid to enable the process parameters to reach the expected values. The regulating valve belongs to a control valve series, mainly functions to regulate parameters such as pressure, flow, temperature and the like of a medium, and is a final control element in a process loop.
The Chinese patent CN2082225690 discloses a pneumatic cage type single-seat regulating valve, which comprises a valve body, a valve cover and a pneumatic film type actuating mechanism which are sequentially arranged from bottom to top, wherein a valve cage is arranged in the valve body, a valve plug is arranged in the valve cage, the valve plug is connected with the pneumatic film type actuating mechanism through a valve rod arranged in the valve cover in a penetrating way, the valve cage is cylindrical, a plurality of medium channels are arranged on the side wall along the circumferential direction, each medium channel consists of a first window hole and a second window hole which are sequentially arranged from bottom to top and communicated with each other, the first window hole is an inverted dovetail-shaped window hole, and the second window hole is a short-neck large window hole; the utility model discloses the noise is little, the reliability is high, sealing performance is good.
