The intelligent electric control valve uses the energy of the medium itself to be adjusted to directly schedule and control the temperature of the medium such as steam, hot water, hot oil and gas, and can also be used to prevent overheating or heat exchange places. The valve has simple structure, convenient operation, wide temperature adjustment range, fast response time, good sealing performance, and can stop scheduling at will during operation, therefore, it is widely used in hot water supply in chemical, petroleum, food, textile, hotels and restaurants.

The valve is driven by manual, worm gear, pneumatic or electric. Ordinary metal sealing ball valve, leakage point more. And the gap around the valve seat, there are often media on its wear, perhaps in the part of the collection, easy to form a valve seat damage.
Before working, the main spool is in the half-open position and the sensor is in the natural state. When the power supply is connected, the main valve core is fully opened. The medium flows into the main valve body in the direction of the arrow and stops heating the heat storage tank through the valve core. It can directly bear the output of industrial control instruments or computers (4-20mADC or 1-5VDC) to stop the opening control of the intelligent electric control valve and reach the intention of dispatching medium pressure, flow and temperature.
Together can output valve position response signal. When the temperature rises to the corresponding set value, the sensor will input the corresponding linear signal into the integrated actuator, then drive the valve stem and valve core to displace, and close the main valve core to stop heating. When the temperature is lower than the set value, the sensor will input the linear signal into the integrated actuator, and the valve core will gradually open, so that the medium will flow into the heat storage tank according to the parabolic characteristics, and the heating will be suspended until the set value. In this way, the controlled medium is controlled within the set temperature range and then reaches the scheduling intention.
