气动薄膜活塞切断阀,气动薄膜隔膜切断阀,气动薄膜单座调节阀,气动薄膜隔膜调节阀,气动薄膜双座调节阀,调节阀在现代化工厂的自动控制中,调节阀起着十分重要的作用,这些工厂的生产取决于流动着的液体和气体的正确分配和控制。 ZMQP Pneumatic diaphragm piston shut-off valve, pneumatic diaphragm diaphragm shut-off valve, pneumatic diaphragm single seat regulating valve, pneumatic diaphragm diaphragm regulating valve, pneumatic diaphragm double seat regulating valve, regulating valve Function, the production of these factories depends on the correct distribution and control of flowing liquids and gases. These controls, whether they are energy exchange, pressure reduction, or simple container charging, require certain final control elements to complete. 体力 The final control element can be considered the " physical force " of automatic control . Between the low energy level of the regulator and the high energy level functions required to perform flowing fluid control, the control element ultimately performs the necessary power amplification.  

Regulating valves are the most widely used version of the final control element. Other final control elements include metering pumps, regulating baffles and louvered baffles (a variant of butterfly valves), variable-slope fan blades, current-regulating devices, and motor positioning devices other than valves.

  Although control valves are widely used, other units in the control system probably do not have as little maintenance work as it does. In many systems, the operating conditions experienced by the regulating valve such as temperature, pressure, corrosion, and contamination are more severe than other components. However, when it controls the flow of process fluids, it must operate satisfactorily and with minimal maintenance the amount.  

The regulating valve acts as a variable resistance in the pipeline. 摩擦 所引起的。 It changes 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 resistance or " friction " of the valve . 节流 This pressure reduction process is often referred to as " throttling . " For gas, it is close to the isothermal adiabatic state, and the deviation depends on the non-ideal degree of the gas (Joule-Thomson effect). In the case of liquids, pressure is consumed by turbulence or viscous friction, both of which convert pressure into thermal energy, resulting in a slight increase in temperature.  

  A common control loop consists of three main parts. The first part is the sensitive element, which is usually a transmitter. It is a device that can be used to measure the parameters of a process, such as pressure, level, or temperature. —— 调节器,它确定并测量给定值或期望值与工艺参数的实际值之间的偏差,一个接一个地把校正信号送出给最终控制元件 —— 调节阀。 The output of the transmitter is sent to the regulating instrument -the regulator, which determines and measures the deviation between the given value or the expected value and the actual value of the process parameter, and sends the correction signal one by one to the final control element - regulation valve. The valve changed the flow of the fluid and brought the process parameters to the desired value.  

In the pneumatic regulating system, the pneumatic signal output by the regulator can directly drive a spring-film actuator or a piston actuator to make the valve act. In this case, the energy required to determine the valve position is provided by compressed air. The compressed air should be dried in outdoor equipment to prevent freezing and should be purified and filtered.
