Imported high-temperature electric control valve
Characteristics of imported high-temperature electric control valve
The fluid is in an open state in the direction of action of the valve core, so the working stability is good.
The bellows seal type forms a complete seal on the moving valve stem to prevent fluid leakage.
The servo amplifier uses deep dynamic negative feedback to improve adjustment accuracy.
The electric high-temperature sleeve regulating valve can directly control the valve opening by current signals without the need for a servo amplifier.
Electric operators come in many forms and can be used for ~ or ~.
In addition to the bushing guide at the valve cover, the side of the valve core and the inner surface of the valve seat also have guiding functions. The guide area is large and the work is reliable.
Saves investment in automation. Compared with single-seat, double-seat or sleeve control valves, one valve can be omitted to form the same system, simplifying the system.
Principle of imported high-temperature electric control valve actuator
The high-temperature electric control valve actuator contains a feeding function, accepts a unified or standard signal, converts the current signal into a corresponding linear displacement, and automatically controls Adjust the valve opening to achieve continuous adjustment of process parameters such as pressure, flow, temperature, and liquid level of the fluid in the pipeline.
Working power supply, equal voltage level.
Input control signal or. The feedback control signal load electrical resistance is below ohms
By receiving signals from the industrial automation control system such as ~, it drives the valve to change the cross-sectional area between the valve core and the valve seat to control process parameters such as flow, temperature, and pressure of the pipeline medium. Realize automatic adjustment function.
Principle of action: Motor power supply or control signal~. There is a controller inside the valve. The controller converts the current signal into the angular stroke signal of the stepper motor. The motor rotates and the valve is driven by gears, levers, or gears plus levers. The rod operates to achieve linear stroke or angular stroke
The feedback motor operates through gear operation, and the three-joint sliding rheostat outputs the positioning signal of the valve. In addition, there are three wires of limit signals for full open and full close. Public line
Overview of imported high-temperature electric control valve
Olshen electric high-temperature control valve is composed of an electric actuator and a high-temperature control valve body. It contains a feeding and serving function and accepts a unified or standard signal. The current signal is converted into the corresponding linear displacement, and the opening of the regulating valve is automatically controlled to achieve continuous adjustment of process parameters such as pressure, flow, temperature, and liquid level of the fluid in the pipeline. The regulating mechanism of the electric high-temperature regulating valve adopts a balanced valve plug structure. The electronic electric high-temperature regulating valve has the characteristics of good valve stability, not easy to vibrate, low noise, low sensitivity to temperature, and allows the use of small pressure differences and large temperatures. Electronic electric high-temperature regulating valves are widely used in situations with large flow, high temperature and loose leakage requirements. Regulating valve]r Regulating valve is used to regulate the flow pressure and liquid level of the medium. According to the signal from the adjustment part, the opening of the valve is automatically controlled to adjust the medium flow pressure and liquid level. Control valves are divided into electric control valves, pneumatic control valves and hydraulic control valves, etc.
