There are many types of locations. The varieties that are known are: slot machine locator mobile phone locator game machine positioner positioner valve positioner GPS positioner. The positioner is the main accessory of the conditioning valve. It is usually used to use the pneumatic conditioning valve. It inherit the output signal of the conditioner, and then use its output signal to control the pneumatic adjustment valve. The installation reaction to the positioner, the valve position is passed to the upper system through the electrical signal.
The positioner is the main accessory of the control valve. It uses the valve stem displacement signal as the input response measurement signal, and the controller output signal is used as a set signal. , Move the action of the execution agency, set the corresponding relationship between the valve pole displacement and the controller output signal. Therefore, the positioner composition uses valve stem displacement as a measuring signal, and controller output as the reaction control system for setting the signal. The dominance variable of the control system is the positioning signal of the positioner to execute the mechanism.
The important conditioning system for high conditioning quality requests is used to improve the accuracy and reliable positioning of the conditioning valve. For places with large pressure differences (△ P> 1MPa) at both ends of the valve. After the output force of the enforcement of the gas source pressure, the unbalanced force produced by the liquid to the valve core by restraining the liquid to reduce the itinerary error.
When the agglutination is high -temperature, high pressure, low temperature, low temperature, toxic, flammable, and explosive, in order to avoid leakage, the filler is often pressed very tightly, so the friction between the valve stem and the filler is large. Can be restrained. When the adjusted medium is viscous fluid or contains solid suspension, the positioner can restrain the resistance of the medium to move the valve stem. Used for a large -caliber (DG> 100mm) conditioning valve to increase the output thrust of the execution agency. When the regulator and the actuator are separated by 60m, the transmission of control signals can be restrained by a locator to improve the movement response speed of the valve.
