A. Heated regulating valve structure and principle of Annex icon: Work before the main spool in the half-open position, the sensor in a natural state. Connected to the power supply, the main spool is full. Medium from the direction of the arrow into the main body, the thermal storage tank is heated by the spool. When the temperature is raised to the appropriate settings, the sensor is generated corresponding linear signal input integration intelligent executive body, then drive the stem, spool displacement, close the main spool to stop heating. When the temperature below the set value, the sensor which produce a linear signal input of the implementing agencies, driven spool involute, so that the media into the thermal storage tank, heating up the settings according to the parabolic nature of. So charged with the media is always controlled within the set temperature range, so as to achieve the purpose of temperature control. Electric temperature control valve main features 1, and the PT-100 PT-500 or PT-1000 temperature sensor, supporting the use of high control precision, fast response. 2, the temperature control setting outside the actuator, set temperature is very convenient. 3, the figures show that the measured temperature, simple and intuitive to understand. Modulating actuator key components - controller, using the most advanced hybrid integrated circuit, after aging treatment, sealed with resin casting was a box-like, moisture-proof, shock-proof, small size, high reliability. 5, the rational design of the upper and lower electric limit function, weak control, safe and durable. 6, the mechanical structure is sturdy and compact line, installation, maintenance is very simple to adjust. Potentiometer adjustment of zero point (the start) and the journey of the (end) the sensitivity of simple. 8, the actuator is overload protection, temperature protection and compression springs to ensure a tight closure of the valve of the three protection function.
