Imported electric temperature control valve introduction (Figure)
Electric temperature control valve (electric temperature control valve), by the control valve, actuators, sensors and capillaries and other components. Divided by the use of heating type and cooling type. Electric temperature control valve (for larger caliber and HTF control), the largest feature of the valve only ordinary 220V power supply, the use of the media itself to adjust the energy directly to the steam, hot water, hot oil and gas and other media temperature Automatic adjustment and control, can also be used to prevent overheating or heat exchange occasions, electric temperature control valve structure is simple, easy to operate, the selection of a wide range of temperature control, fast response time, reliable sealing performance, and can be adjusted freely in operation, It is widely used in chemical, petroleum, food, textile, hotels and restaurants and other departments of hot water supply. Electric thermostat is mainly suitable for liquid, gas and steam, temperature control in a variety of cooling systems. When the controlled medium temperature rises, the control valve is closed (heating type); when the controlled medium temperature rises, the control valve is open (cooling type). The main features are as follows: 1, high control accuracy, stable work, safe and reliable. 2, the temperature of the liquid even expansion, proportional adjustment control. 3, the temperature setting is simple, easy to adjust. 4, small size, light weight, easy to install. Electric temperature control valve works: Electric temperature control valve by the control valve, electric actuator, temperature sensor and temperature regulator and other components, according to user needs, respectively, heating and cooling of two structures. The structure and principle of the heating type control valve: Before working, the main valve core is in the half-open position, and the sensor is in a natural state. Connect the power, the main spool fully open. The medium flows into the main valve body in the direction of the arrow, and the heat storage tank is heated by 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, the valve spool displaces and closes the main valve plug 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 element to be involute, allowing the medium to flow into the heat storage tank according to the parabolic characteristic and heating up to the set value. This controlled media is always in the set temperature range is controlled, so as to achieve the purpose of temperature control. Note: often say that the heating type, cooling type. In this valve as long as the spool structure can be replaced. Imported electric temperature control valve
