Abstract
Description
Technical Field
[0001] This utility model relates to the field of regulating valve technology, specifically to an electrically heated anti-icing electric regulating valve. Background Technology
[0002] Control valves, as key components of industrial automation control systems, play a vital role in numerous fields such as petroleum, chemical, power, metallurgy, and construction. By changing the throttling area, they regulate parameters such as the flow rate, pressure, and temperature of media (e.g., gases and liquids), ensuring the stable and efficient operation of various industrial processes.
[0003] Existing control valves lack anti-icing capabilities. In cold regions or low-temperature environments, when a medium containing moisture flows through the control valve, the moisture freezes in critical components such as the valve body, valve seat, and valve core due to the ambient temperature being below freezing. Icing not only increases flow resistance and reduces flow control accuracy, leading to system parameter malfunction and affecting production stability, but it can also damage valve components due to the expansion force of ice, such as deformation of the valve seat sealing surface and valve core jamming, causing valve leakage, safety accidents, and significant economic losses. Therefore, we propose an electrically heated anti-icing electric control valve. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an electrically heated anti-icing electric regulating valve. This valve possesses the advantage of anti-icing, solving the problem that existing regulating valves lack anti-icing functionality. In cold regions or low-temperature environments, when a medium containing moisture flows through the regulating valve, the moisture freezes in critical parts such as the valve body, valve seat, and valve core due to the ambient temperature being below freezing. Icing not only increases the flow resistance of the medium, reduces the accuracy of flow regulation, and leads to loss of system parameter control, affecting production stability, but it can also damage valve components due to the expansion force of ice, such as deformation of the valve seat sealing surface and jamming of the valve core, causing valve leakage, triggering safety accidents, and resulting in huge economic losses.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrically heated anti-icing electric regulating valve, comprising a housing, a valve body fixedly connected to the central axis at the top of the inner wall of the housing, a temperature sensor fixedly connected to the left front end of the top of the inner cavity of the housing, a motor fixedly connected to the top of the inner cavity of the housing and to the left side of the central axis, a drive gear fixedly connected to the output end of the motor, a driven gear meshing with the left side of the drive gear, a crankshaft fixedly connected to the inner cavity of the driven gear, a frame fixedly connected to one side of the crankshaft, a motor fixedly connected to one side of the inner cavity of the frame, a fan blade fixedly connected to the output end of the motor, and a heating mesh fixedly connected to one side of the frame.

[0007] Preferably, the top of the crankshaft is movably connected to the housing via a bearing, and the front of the housing is movably connected to a movable door.
[0008] Preferably, water guide pipes are connected to both sides of the valve body via flanges, and the outer side of the water guide pipe extends to the outer side of the housing.
