Description

Technical Field

[0001] This utility model relates to the field of solenoid valve technology, and more specifically, to a high-temperature resistant solenoid valve. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices. They are basic components of automation used to control fluids and are used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium.

[0003] Existing solenoid valves lack the function of quickly dissipating heat from their internal coils. During operation, the coil generates heat as electrical energy is converted into magnetic energy. If heat is not dissipated in time, the coil may overheat, affecting the normal operation of the solenoid valve or even causing damage. Therefore, they are not suitable for use in high-temperature environments. Utility Model Content

[0008] Furthermore, a temperature sensor is installed on the working chamber to control the starting and stopping of the motor.

[0009] Furthermore, the heat dissipation fins are arranged in multiple groups around the coil, and the heat dissipation fins are made of copper.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 A high-temperature resistant solenoid valve includes a valve body 1, an internal working chamber 2, and a coil 3 installed within the working chamber 2. The working chamber 2 is a sealed structure filled with a fluorinated liquid. Because the fluorinated liquid has high thermal conductivity and is non-conductive, it can effectively absorb heat transferred to the working chamber 2 without causing a short circuit in the coil 3. Heat dissipation fins 4 are arranged on the outer wall of the working chamber 2 in multiple groups around the coil 3. One end of each heat dissipation fin extends into the working chamber 2, and the other end extends outward. The heat dissipation fins 4 are made of copper, which has good thermal conductivity. Multiple sets of heat dissipation fins 4 can increase the heat exchange between the inner cavity of the working chamber 2 and the outside, thereby quickly dissipating the heat of the fluorinated liquid inside the working chamber 2 to the outside. A ring fan 5 is rotatably sleeved on the working chamber 2. The ring fan 5 is located at the lower end of the working chamber 2 and faces upward toward the heat dissipation fins 4. The valve body 1 is also provided with a drive component that acts on the ring fan 5 to control the ring fan 5 to rotate. When the ring fan 5 rotates, it generates airflow that blows toward the heat dissipation fins 4 above, thereby providing wind cooling for the heat dissipation fins 4 that extend out of the working chamber 2, so as to accelerate the conduction of heat on the heat dissipation fins 4 to the outside environment.

[0022] During operation, the heat generated by the coil 3 is evenly absorbed by the fluorinated liquid inside the working chamber 2. Multiple sets of heat dissipation fins 4 extending into the working chamber 2 quickly conduct the heat to the outside of the chamber. At this time, the drive assembly controls the ring fan 5 to rotate. The ring fan 5 rotates and generates airflow that blows upwards onto the heat dissipation fins 4 extending outwards from the working chamber 2, allowing the heat on the heat dissipation fins 4 to dissipate quickly into the external environment. Therefore, through the combined action of the fluorinated liquid filling the working chamber 2, the heat dissipation fins 4, the ring fan 5, and the drive assembly, the heat in the working chamber 2 can be quickly conducted and dissipated into the external environment, providing rapid and effective cooling for the coil 3. This prevents the coil 3 from operating in a high-temperature environment inside the working chamber 2, ensuring the performance of the coil 3.

[0023] For further details, please refer to Figure 1-4 The drive assembly includes a motor 6 mounted on the terminal block on the outside of the working chamber 2, a rotating shaft 7 connected to one end of the output shaft of the motor 6, a gear 8 sleeved on the surface of the rotating shaft 7, and a gear ring 9 set on the annular fan 5 and meshing with the gear 8. The rotating shaft 7 can be driven to rotate by the motor 6, and the rotating shaft 7 can be controlled to rotate by the meshing transmission action of the gear 8 and the gear ring 9.

[0024] For further details, please refer to Figure 1-4 A temperature sensor 18 is installed in the working chamber 2 to control the start and stop of the motor 6. The contacts of the temperature sensor 18 extend into the working chamber 2. When it detects that the temperature inside the working chamber 2 is higher than the set threshold, the temperature sensor 18 can control the motor 6 to start, thereby accelerating the cooling of the working chamber 2. When it detects that the temperature inside the working chamber 2 is lower than the set threshold, the temperature sensor 18 can control the motor 6 to stop. The start and stop of the motor 6 can be intelligently controlled according to the temperature inside the working chamber 2 to achieve the purpose of energy saving.

[0025] For further details, please refer to Figure 1-4The valve body 1 has an air inlet 10 and an air outlet 11. A valve seat 12 is located inside the valve body 1, between the air inlet 10 and the air outlet 11. A sliding cavity 13 is located inside the working chamber 2 of the valve body 1. A moving iron core 14 is slidably mounted inside the sliding cavity 13. The moving iron core 14 is positioned above the valve seat 12, and a sealing plug 15 is located at its bottom end. A push rod 16 is located above the sliding cavity 13, with its bottom end extending into the sliding cavity 13 and fitted with a spring 17. When the coil 3 inside the solenoid valve is energized, the push rod 16 generates a magnetic force that attracts the moving iron core 14 upwards, causing the moving iron core 14 to move upwards along the sliding cavity 13. When the valve seat 12 slides, it separates from the sealing plug 15 at the bottom of the moving iron core 14, allowing gas to flow through the inlet 10 and outlet 11. The solenoid valve is in the open state. As the moving iron core 14 moves upward, it compresses the spring 17 at the bottom of the push rod 16. At this time, the spring 17 exerts a downward elastic force on the moving iron core 14. When the coil 3 inside the solenoid valve is de-energized, the push rod 16 no longer exerts a magnetic attraction on the moving iron core 14. At this time, the moving iron core 14 slides downward under the elastic force of the spring 17, causing the sealing plug 15 at the bottom of the moving iron core 14 to seal the valve seat 12, and the solenoid valve is in the closed state.

[0026] For further details, please refer to Figure 1-4 A filter screen 19 is provided on one side of the air inlet 10. The filter screen 19 can intercept impurities in the medium. The impurities enter the interior of the valve body 1 and cause the valve seat 12 inside the valve body 1 to become blocked.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
