[0002] In fields such as industrial automation, automotive thermal management systems, medical equipment, and fire protection, solenoid valves are widely used as key fluid control components for controlling the on / off state and flow regulation of liquids or gases. Traditional solenoid valves typically use an electromagnetic coil to drive the valve core, controlling the opening and closing of the valve by energizing or de-energizing it. However, existing solenoid valves still suffer from the following significant problems:

[0003] Traditional solenoid valves require continuous power to remain open. In energy-sensitive applications such as electric vehicles, long-term operation will significantly increase power consumption and affect driving range.

[0031] Example

[0032] like Figures 1-4 As shown, this utility model provides an electric drive device for electromagnetic valves, automotive valves, and fire valves, comprising:

[0033] Valve body 1, which is provided with inlet 2 and outlet 3;

[0034] An electromagnetic drive assembly consisting of a permanent magnet 4, a double-winding coil 5, a valve stem 6, and a valve core 7 is installed inside the valve body 1.

[0035] The control module enables three driving modes: high voltage, low voltage, and power failure.

[0036] The outlet 3 is equipped with a low flow channel 301 and a high flow channel 302.

[0037] Specifically: Fluid flows in through inlet 2 and out through outlet 3. During the flow, the dual-winding coil 5 is energized to control the linear reciprocating movement of the valve stem 6 and valve core 7, including the following three modes:

[0038] Firstly, when the temperature of the new energy battery is higher than 40℃, the main coil in the double-winding coil 5 is 24V, and the valve core 7 is in the high-flow channel 303 to ensure the high-speed flow of the coolant and achieve a rapid cooling effect.

[0039] Secondly: The temperature of the new energy battery is between 10℃ and 40℃, the energy-saving coil of the double-winding coil 5 is 5V, and the valve core 7 is in the low flow channel 301 to maintain the low flow of coolant.

[0040] Thirdly: When the temperature of the new energy battery is below 10℃, turn off the power. Under normal conditions, valve core 7 is used to close outlet 3.

[0041] It is understandable that the voltage of the dual-winding coil 5 is adjusted in real time according to the temperature to reduce energy consumption and improve battery life.

[0042] Similarly, by changing the flow rate of outlet 3, it can be applied to the fire protection field, such as adjusting the water output of fire protection pipelines to achieve water-saving functions.

[0043] The valve body 1 has a sealing groove for installing a double-winding coil 5 and a permanent magnet 4. The valve body 1 also has a sliding groove. The valve stem 6 is elastically set in the sliding groove by a spring 8. The end of the valve stem 6 is fixedly connected to the valve core 7. The spring 8 is used for the elastic reset of the valve stem 6 and the valve core 7. When the power is turned off, the valve core 7 can block the outlet 3.

[0044] The main coil resistance of the double-winding coil 5 is R1 = 8Ω, and the energy-saving coil resistance is R2 = 80Ω.

[0045] Valve core 7 is made of polyetheretherketone material, with a temperature resistance of -40℃ to 220℃, which improves stability and adapts to different temperature changes of coolant.

[0046] Permanent magnet 4 is made of neodymium iron boron material, which improves the performance of the magnet.
