SENMIWK series steam three-way control valve (electric three-way temperature control valve) is composed of three-way control valve, actuator, sensor and capillary tube. Divided into heating type and cooling type according to purpose. Steam three-way control valve (applicable to larger diameter and heat-conducting oil control), the valve features only a common 220V power supply, the use of self-adjusted media energy, direct temperature of steam, hot water, hot oil and gas and other media Implementation of automatic adjustment and control, can also be used to prevent overheating or heat exchange applications, electric three-way temperature control valve structure is simple, easy to operate, select a wide temperature range, fast response time, reliable sealing performance, and can be freely in operation The regulation is applied to hot water supply in chemical, petroleum, food, textile, hotel and restaurant sectors.
The steam three-way control valve is mainly used for liquid, gas and steam, temperature control in various cooling systems. When the temperature of the controlled medium increases, the control valve is closed (heating type); when the temperature of the controlled medium increases, the control valve is opened (cooled type). The main features are as follows:
1. High control accuracy, stable operation, safety and reliability.
2, temperature-sensing liquid expansion evenly, proportional adjustment control.
3, the temperature setting is simple and easy to adjust.
4, small size, light weight, easy installation.
Operation principle of steam three-way control valve The steam three-way control valve is composed of control valves, electric actuators, temperature sensors and temperature regulators. According to the needs of users, there are two types of structures: heating type and cooling type. The structure and principle of the heating type regulating valve: Before the work, the main valve core is in the semi-open position, and the sensor is in the natural state. Connect the power supply and the main spool is fully open. The medium flows into the main valve body from the direction of the arrow and heats the heat storage tank through the valve body. When the temperature rises to the corresponding set value, the sensor will generate the corresponding linear signal input integrated actuator, then drive the valve stem, spool displacement, close the main valve core to stop heating. When the temperature is lower than the set value, the sensor generates a linear signal input integrated actuator, which drives the valve core to open gradually so that the medium flows into the heat storage tank according to the parabola characteristic and is heated until it reaches the set value. In this way, the controlled medium is always controlled within the set temperature range so as to achieve temperature control. Remarks: often said heating, cooling type. In this valve, only the replacement of the valve core structure can be achieved.
