Electronic self-modulating temperature control valve
Electronic self-modulating temperature control valve
Electronic self-modulating temperature control valve Product introduction
China Electronic temperature control valve manufacturer, factory and supplier. Electronic self-modulating temperature control valve is composed of control valve, electric actuator, sensor and capillary. Electronic self-modulating temperature control valve is divided into heating type and cooling type by use. Electronic self-modulating temperature control valve (applicable to larger diameters and heat conduction oil control), the characteristic of the valve just ordinary 220 v power supply and use energy modulated medium itself, directly to the media such as steam, hot water, hot oil and gas temperature automatic adjustment and control, also can use in preventing overheating or heat exchange.Electronic self-modulating temperature control valve has simple structure, convenient operation, Wide range of temperature regulation, fast response time, reliable sealing performance, and can be adjusted at will in operation, so it is widely used in chemical, petroleum, food, textile, hotels and restaurants and other departments of hot water supply.
Electronic self-modulating temperature control valve is mainly used for liquid, gas and steam, temperature control in a variety of cooling systems. When the temperature of the controlled medium rises, the control valve is closed (heating type); When the temperature of the controlled medium rises, the control valve opens (cooling type).
The main features are as follows:
1. High control precision, stable work, safe and reliable.
2. Temperature sensitive liquid expansion uniform, proportional adjustment control.
3. The temperature setting operation is simple, easy to adjust.
4. Small size, light weight, easy to install.
Electronic self-modulating temperature control valve working principle:
The main valve core of Self-modulating temperature control valveis in the half-open position and the sensor is in the natural state.After connecting to the power supply, the main valve is fully open.The medium flows into the main valve body by the direction of the arrow and heats the heat storage box by the valve core.When the temperature is higher than the set value, the temperature sensor generates corresponding linear signal input electric actuator produces an axial action, driving the stem and valve core to produce linear displacement, close the main valve core to stop heating.When the temperature of the electronic temperature control valve is lower than the set value, the sensor also generates corresponding linear signal input to the electric actuator, driving the control valve core to open, making the medium flow into the heat storage box according to the parabolic characteristics, and heating until the set value.Repeated circulation, so that the temperature of the controlled medium is always kept in the set range, so as to achieve the purpose of automatic control, this is the working principle of the electronic temperature control valve.
