AI Technical Summary
In low-temperature winter environments, solenoid valves are prone to freezing, causing the valve core to malfunction. Existing heating devices are slow to transfer heat and lack intelligence, resulting in high energy consumption.
A temperature sensor is directly attached to the surface of the solenoid valve, combined with a digital display intelligent fully automatic temperature controller and a glass fiber electric heating strip, to achieve rapid temperature sensing and precise control. The electric heating strip is wrapped around the solenoid valve and valve seat, and the temperature threshold is set by the digital display intelligent fully automatic temperature controller to automatically heat and prevent freezing.
It enables rapid sensing and accurate control of the surface temperature of the solenoid valve, preventing icing, ensuring stable operation of the equipment for extended periods, and reducing energy waste.
