 The valve is often used in important industrial production and people's livelihood, and its safe and reasonable use is very important. In terms of safety, it is easy to cause safety problems and environmental pollution problems after a leak, causing great losses to investors and society. Reasonably speaking, there is a big gap between the size of the valve configuration and the cost, and the valve switching characteristics have a great influence on the process production. Most of our original model selection is based on empirical data. It is difficult to adjust and it is difficult to judge whether your valve selection has problems .
Conventional valves have difficulties in leak detection, and it is often necessary to have special equipment to judge the failure of the valve. Generally, the factory is rarely equipped, even if it is equipped, it is difficult to check in time. There is a large investment. Disadvantages.
Moreover, many industrial valves are expensive, and the conditions of use vary greatly. How to track the use of the valve and develop the corresponding products according to the use of the situation can only rely on human response, there is no unified data basis.
Valves are often used in important industrial production and people's livelihood occasions. After a leak, it is easy to cause safety problems and environmental pollution problems, causing great losses to investors and society.

The working principle of the pneumatic valve positioner is that it and the pneumatic actuator constitute an automatic control unit and various regulating valves are connected to each other after debugging and installation, and then combined into a pneumatic regulating valve. It is used in various industrial automation process control fields.
Pneumatic valve positioner receives a weak current signal from the controller or control system of 4 ~ 20mA, and sends an air signal to the pneumatic actuator to control the valve position.
It is used in conjunction with pneumatic control valves to form a closed-loop control loop. Convert the DC current signal given by the control system to the gas signal that drives the regulator valve to control the action of the regulator valve. At the same time, it feedbacks according to the opening of the regulating valve, so that the valve position can be correctly positioned according to the control signal output by the system.
The pneumatic valve positioner works according to the principle of torque balance. When the signal pressure P1 into the bellows 2 increases, the main lever 3 rotates around the fulcrum, so that the nozzle baffle 9 approaches the nozzle. The nozzle back pressure is amplified by the unidirectional amplifier 8 After that, the pressure into the membrane chamber of the actuator increases, causing the valve stem to move downward. And drive the feedback lever to rotate around the fulcrum, and the feedback cam also rotates counterclockwise. The auxiliary lever 4 rotates around the fulcrum through the roller, and the feedback spring is stretched. The tension and signal pressure of the spring on the main lever 3 are used in the bellow When the force on reaches the moment balance, the instrument reaches the balance state. The valve position of the actuator is maintained at a certain opening degree, and a certain signal pressure corresponds to a certain valve position opening degree. The above action mode is positive action, if you want to change the action mode, as long as the cam is flipped, A direction becomes B direction, etc. The so-called positive acting positioner means that the signal pressure increases and the output pressure also increases; the so-called negative acting positioner means that the signal pressure increases and the output pressure decreases. As long as a positive acting actuator is equipped with a reaction positioner, it can realize the action of the reaction actuator; on the contrary, as long as a reaction actuator is equipped with a reaction positioner, it can realize the action of the positive action actuator.

The difference between ordinary electric valve positioner and intelligent electric valve positioner
Do you know the difference between ordinary electric valve positioner and intelligent electric valve positioner? What are the advantages of intelligent electrical valves, let's take a look at it together.
Valve locator, divided into pneumatic valve locator, electro-pneumatic valve locator and intelligent valve locator according to the structure, is the main accessory of the control valve, usually used in conjunction with the pneumatic control valve, it accepts the output signal of the regulator, and then The 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 positioner through the mechanical device, and the valve position status is transmitted to the upper system through the electrical signal.
Intelligent electrical valve positioners are widely used for positioning control of pneumatic linear or angular actuators. It converts the current signal output from the control room into the gas signal that drives the control valve. According to the friction force of the valve stem when the control valve is working, the unbalanced force generated by the pressure fluctuation of the medium is offset, and the valve opening corresponds to the control room output.
According to whether the valve positioner is equipped with CPU, it can be divided into ordinary electric valve positioner and intelligent electric valve positioner. Ordinary electrical valve positioners do not have a CPU, so they do not have intelligence and cannot handle related intelligent operations. The intelligent electric valve positioner has a CPU, which can handle related intelligent operations, for example, non-linear compensation of the forward channel, etc., and the fieldbus electric valve positioner can also have PID and other functional modules to realize the corresponding operation.
The above is about the difference between ordinary electrical valve positioners and intelligent electrical valve positioners. Siemens Industrial Automation sells well in the consumer market and enjoys a high position among consumers. Delsmann is a partner of Siemens Industrial Automation and Drive Group and comprehensive competition Strength is constantly increasing.

Explain the working principle of Siemens electric valve positioner
With the development of smart instrument technology, microelectronic technology is widely used in traditional instruments, which greatly improves the function and performance of the instrument. Siemens electric valve positioner is the main accessory of the regulating valve, usually used with pneumatic regulating valve. It accepts the output signal of the regulator, and then uses its output signal to control the pneumatic regulating valve. When the regulating valve acts, the displacement of the valve stem It is fed back to the valve positioner through a mechanical device, and the valve position status is transmitted to the upper system through an electrical signal.
According to the working principle, the positioner can be divided into: pneumatic positioner, electric positioner, intelligent positioner
The working principle of electric valve positioner. The electric valve positioner is the main accessory of the control valve. It uses the valve stem displacement signal as the input feedback measurement signal, and the controller output signal as the set signal for comparison. The output signal causes the actuator to move, establishing a one-to-one correspondence between the displacement of the valve stem and the output signal of the controller. Therefore, the valve positioner constitutes a feedback control system that uses the displacement of the valve stem as the measurement signal and the output of the controller as the set signal. The manipulated variable of this control system is the output signal from the valve positioner to the actuator.

Siemens Intelligent Valve Models
---- Low gas consumption-low cost operation brought by low gas consumption
---- Another significant feature of SIPART PS2 is its extremely low gas consumption. The traditional valve positioner will have a lot of instrument air discharge or leakage during work, resulting in a large demand for instrument air and high operating costs. Due to the new piezoelectric valve technology, SIPART PS2 will not emit any instrument air when the valve is not actuated, and it will use gas when the valve is most needed-the valve actuation.
---- Abundant diagnostic functions-make every event under control
---- The new SIPART PS2 can provide more parameters and additional diagnostic information.
