Hebei JiuyunDWPD steam electric control valvemanufacturer

　　Steam electric regulating valveSteam regulating valve temperature regulating valve (electric temperature control valve), model: DWPD; The steam electric regulating valve consists of control valve, actuator, sensor, capillary tube and other components. Steam electric regulating valves are divided into heating and cooling types according to their applications. Steam electric control valve (suitable for larger diameters and thermal oil control), the characteristics of steam electric control valve are that it only requires a normal 220V power supply and uses the energy of the regulated medium to directly adjust and control the temperature of steam, hot water, hot oil, gas and other media. It can also be used to prevent overheating or heat exchange. The steam electric control valve has a simple structure, easy operation, wide temperature adjustment range, fast response time, reliable sealing performance, and can be adjusted freely during operation. Therefore, it is widely used in the hot water supply of chemical, petroleum, food, textile, hotel and restaurant departments.

Steam regulating valve is mainly suitable for temperature control of liquids, gases, and steam in various cooling systems. When the temperature of the controlled medium increases, the control valve closes (heating type); When the temperature of the controlled medium increases, the control valve opens (cooling type).

　　Hebei Jiuyun Steam Electric Control Valveworking principle:

The steam electric regulating valve consists of control valves, electric actuators, temperature sensors, and temperature regulators. According to user needs, there are two types of structures: heating and cooling. The structure and principle of steam electric regulating valve: Before operation, the main valve core is in a semi open position, and the sensor is in a natural state. Connect the power supply and fully open the main valve core. The medium flows into the main valve body in the direction of the arrow and heats the thermal storage tank through the valve core. When the temperature rises to the corresponding set value, the sensor generates a corresponding linear signal input to the integrated actuator, which then drives the valve stem and valve core to produce displacement, and closes the main valve core to stop heating. When the temperature is lower than the set value, the sensor generates a linear signal input to the integrated actuator, which drives the valve core to gradually open, causing the medium to flow into the heat storage tank according to parabolic characteristics and heat up until the set value. In this way, the controlled medium is always controlled within the set temperature range, thus achieving the purpose of temperature control. Note: Commonly referred to as heating type and cooling type. This can be achieved by simply replacing the valve core structure in this valve.
