Description

Technical Field

[0001] The present invention relates to the technical field of solenoid valves, in particular to a large-caliber high-pressure solenoid valve. Background Art

[0002] Various solenoid valves are often used in thermal management systems to control and regulate fluid media. Common solenoid valves, such as the valve body assembly, solenoid valve, integrated valve, thermal management system, and vehicle disclosed in patent application publication number CN118224368A, and the solenoid valve, thermal management system, and vehicle disclosed in utility model patent publication number CN220168716U, all enable flow regulation.

[0003] However, it was found during use that the larger the diameter of the solenoid valve, the worse the high-pressure valve opening ability, and even the valve cannot be opened. Therefore, there is an urgent need for a large-diameter high-pressure solenoid valve to improve the above problem. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a large-diameter, high-pressure solenoid valve, which provides power to the valve core assembly through the coil assembly when the large-diameter, high-pressure solenoid valve is closed, and through the pressure difference between the top and bottom of the valve body assembly, the valve core closes the interior of the valve body assembly, preventing the medium from flowing through the valve body assembly, thereby improving the practicality of the equipment.

[0005] A large-caliber, high-pressure solenoid valve of the present invention comprises a coil assembly, a valve body assembly, and a valve core assembly, wherein the coil assembly is mounted on the valve body assembly, and the valve core assembly is mounted between the coil assembly and the valve body assembly; The coil assembly provides power to the valve core assembly, and the valve body assembly cooperates with the valve core assembly to control the flow of the medium; When the large-diameter, high-pressure solenoid valve is closed, the coil assembly provides power to the valve core assembly, and the pressure difference between the top and bottom of the valve body assembly causes the valve core to close the interior of the valve body assembly, preventing the medium from flowing through the valve body assembly, thereby improving the practicality of the equipment.

[0006] Preferably, the valve body assembly includes a valve seat and a valve cover assembly, and the valve cover assembly is installed on the top of the valve seat;.

[0007] Preferably, an air inlet is provided at the side end of the valve seat, and an air outlet is provided at the bottom of the valve seat; when the large-caliber high-pressure solenoid valve is opened, the medium passes through the air inlet, the inside of the valve seat and the air outlet in sequence.

[0008] Preferably, the valve core assembly includes a moving iron core, a static iron core, a valve needle, a secondary rubber pad, a return spring, a valve core and a main rubber pad. The moving iron core and the static iron core are both installed in the coil assembly. The bottom of the moving iron core is in the shape of a truncated cone, and the top of the static iron core is in the shape of a truncated cone hole corresponding to the bottom of the moving iron core. The valve needle is installed on the moving iron core, and the bottom of the valve needle passes through the moving iron core. The secondary rubber pad is installed at the bottom of the valve needle. The return spring is located in the groove of the valve cover assembly to support the valve needle. The valve core is slidably installed inside the valve seat, and the main rubber pad is installed at the bottom of the valve core; the coil assembly is energized to generate a magnetic field, so that the moving iron core drives the valve needle to move downward, the return spring contracts, and the secondary rubber pad covers the valve cover assembly, thereby forming a high-pressure area above the valve core, and the valve core is squeezed downward by the high pressure, so that the valve core moves downward, and the air outlet on the coil assembly is sealed by the main rubber pad to close the large-caliber high-pressure solenoid valve, thereby improving the practicality of the equipment.

When closing the large-caliber high-pressure solenoid valve, the coil assembly drives the moving iron core to descend, causing the auxiliary rubber pad to seal the air supply hole one, thereby blocking the medium flowing into the groove on the top of the valve cover assembly, causing the pressure in the space between the valve core and the valve cover assembly to rise instantly. The valve core is squeezed downward by the high pressure generated, and the air outlet at the bottom of the valve seat is sealed by the main rubber pad to close the large-caliber high-pressure solenoid valve, thereby improving the practicality of the equipment.

[0010] Preferably, a spring is provided inside the coil assembly, and the top of the spring is mounted on the valve core; when the large-diameter high-pressure solenoid valve is opened, the valve core is supported upward by the elasticity of the spring to ensure the open state of the large-diameter high-pressure solenoid valve.

On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0017] Example: Figures 1 to 6 As shown, a large-caliber high-pressure solenoid valve includes a coil assembly 1; a valve body assembly and a valve core assembly, wherein the coil assembly 1 is mounted on the valve body assembly, and the valve core assembly is mounted between the coil assembly 1 and the valve body assembly; The coil assembly 1 provides power to the valve core assembly, and the valve body assembly cooperates with the valve core assembly to control the flow of the medium; The valve body assembly includes a valve seat 2 and a valve cover assembly 3, and the valve cover assembly 3 is installed on the top of the valve seat 2; The side end of the valve seat 2 is provided with an air inlet 4, and the bottom of the valve seat 2 is provided with an air outlet 5; The valve core assembly includes a moving iron core 6, a static iron core 7, a valve needle 8, a secondary rubber pad 9, a return spring 10, a valve core 11 and a main rubber pad 12. The moving iron core 6 and the static iron core 7 are both installed in the coil assembly 1. The bottom of the moving iron core 6 is truncated cone-shaped, and the top of the static iron core 7 is a truncated cone hole corresponding to the bottom of the moving iron core 6. The valve needle 8 is installed on the moving iron core 6, and the bottom of the valve needle 8 passes through the moving iron core 6. The secondary rubber pad 9 is installed at the bottom of the valve needle 8. The return spring 10 is located in the groove of the valve cover assembly 3 to support the valve needle 8. The valve core 11 is slidably installed inside the valve seat 2, and the main rubber pad 12 is installed at the bottom of the valve core 11; A small exhaust hole 26 is provided at the bottom of the valve seat 2, a groove is provided at the top of the valve cover assembly 3, an air supply hole 13 and an air supply hole 2 14 are provided in the middle of the valve cover assembly 3, and the groove of the valve cover assembly 3 is communicated with the small exhaust hole 26 through the air supply hole 13, and the groove of the valve cover assembly 3 is communicated with the space between the valve core 11 and the valve cover assembly 3 through the air supply hole 2 14, and the valve core 11 is provided with an air supply hole 3 15 and an air supply hole 4 16, and the air supply hole 3 15 is communicated with the interior of the air supply hole 4 16, and the top of the air supply hole 4 16 extends above the valve core 11; A spring 17 is provided inside the coil assembly 1, and the top of the spring 17 is sleeved on the valve core 11; A bracket 18 is provided on the top of the valve seat 2; The outer ring of the valve seat 2 and the outer ring of the valve cover assembly 3 are both provided with sealing rings; When the large-caliber high-pressure solenoid valve is in the open state, the valve needle 8 is supported upward by the return spring 10, and the valve core 11 is supported upward by the spring 17. The medium flows through the air inlet 4, the interior of the valve seat 2 and the air outlet 5 in sequence to pass through the large-caliber high-pressure solenoid valve.

The medium between the valve core 11 and the valve cover assembly 3 flows through the air supply hole 2 14, the groove on the top of the valve cover assembly 3 and the air supply hole 13 in turn, and is then discharged through the small exhaust hole 26, so that the pressure in the space between the valve core 11 and the valve cover assembly 3 is reduced. At the same time, the elasticity of the spring 17 resets the valve core 11, and the medium flows through the air inlet 4, the inside of the coil assembly 1 and the air outlet 5 again to pass through the large-diameter high-pressure solenoid valve, thereby improving the practicality of the equipment.
