SSS locator manufacturer delivers quicklyCE152-SB6/M0 M1 Our advantages:The Japanese SSS Solies valve locator is a high-precision positioning device that can be used for positioning and control of various valves, with high reliability and accuracy
定位器作用原理:

(1) Used for important regulating systems with high quality requirements to improve the positioning and reliability of regulating valves

(2) Used in situations where the pressure difference between the two ends of the valve is large (4p>1MPa). By increasing the pressure of the gas source, the output force of the actuator is increased to overcome the unbalanced force generated by the liquid on the valve core and reduce the stroke error.

(3) When the medium being adjusted is high temperature, high pressure, low temperature, toxic, flammable, or explosive, in order to prevent external leakage, the packing is often pressed tightly, resulting in a high frictional force between the valve stem and the packing. At this time, a locator can be used to overcome it

Service delay.

(4) When the medium being adjusted is a viscous fluid or contains suspended solids, a locator can overcome the resistance of the medium to the movement of the valve stem.

(5) Used for regulating valves with large diameters (Dg>100mm) to increase the output thrust of the actuator.

(6) When the distance between the regulator and the actuator is over 60m, using a locator can overcome the delay in the transmission of control signals and improve the reaction speed of the valve action,

(7) Used to improve the flow characteristics of regulating valves

(8) When a regulator controls two actuators to implement split range control, two locators can be used to receive low input signals and high input signals respectively. One actuator will perform a low range action and the other will perform an elevation action, which constitutes split range regulation.

Valves, classified by structure into pneumatic valves, electric pneumatic valves, and intelligent valves, are the main accessories of regulating valves and are usually used in conjunction with pneumatic regulating valves. They receive output signals from regulators,

Then, its output signal is used to control the pneumatic regulating valve. When the regulating valve is activated, the displacement of the valve stem is fed back to the valve through a mechanical device, and the valve position is transmitted to the upper system through an electrical signal.

Structure: Valves can be divided into pneumatic valves, electric pneumatic valves, and intelligent valves according to their structural form and working principle. Valves can increase the output power of regulating valves and reduce the occurrence of delayed transmission of regulating signals,

Accelerating the movement speed of the valve stem can improve the linearity of the valve, overcome the frictional force of the valve stem, and eliminate the influence of unbalanced force, thereby adjusting the correct positioning of the valve. Classification: Valves are classified into pneumatic valves based on input signals

Electric pneumatic valves and intelligent valves. The input signal of a pneumatic valve is a standard gas signal, such as a 20-100kPa gas signal, and its output signal is also a standard gas signal. The input signal of an electrical valve is a standard current or voltage signal,

For example, 4-20mA current signal or 1-5V voltage signal, etc., the electrical signal is converted into electromagnetic force inside the electrical valve, and then the gas signal is output to the toggle control valve. Intelligent electrical valve converts the current signal output from the control room

The gas signal that drives the regulating valve is used to counteract the unbalanced force caused by individual pressure fluctuations based on the friction force of the valve stem during the operation of the regulating valve, so that the valve opening corresponds to the current signal output from the control room, and can be intelligently configured

Set corresponding parameters to improve the performance of the control valve.

According to the direction of action, it can be divided into one-way valves and two-way valves. When a one-way valve is used for a piston actuator, the valve only functions in one direction, while a two-way valve acts on both sides of the cylinder of the piston actuator, acting from two directions.

According to the gain sign of the output and input signals of the valve, it is divided into positive acting valves and reverse acting valves. When the input signal of the positive action valve increases, the output signal also increases, so the gain is positive. When the input signal of the reaction valve increases,

The output signal decreases, therefore the gain is negative. According to whether the valve input signal is an analog signal or a digital signal, it can be divided into ordinary valves and fieldbus electrical valves. The input signals of ordinary valves are analog air pressure, current, and voltage signals,

The input signal of the fieldbus electrical valve is the digital signal of the fieldbus. According to whether the valve is equipped with a CPU, it can be divided into ordinary electrical valves and intelligent electrical valves. Ordinary electrical valves do not have a CPU, therefore they do not have intelligence,

Cannot handle related intelligent operations. Intelligent electrical valves are equipped with CPUs that can handle intelligent calculations, such as non-linear compensation for forward channels. Fieldbus electrical valves can also be equipped with functional modules such as PID to achieve corresponding calculations.
