Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valves, in particular to a electromagnetic valve structure. Background Art

[0002] As a key control component, solenoid valves are widely used in many fields such as industrial automation, automobiles, aerospace, and household appliances. If the heat generated by traditional solenoid valves during operation cannot be effectively dissipated, it will not only affect the working efficiency of the solenoid valve, but may also cause overheating damage and even cause safety hazards to surrounding equipment. Traditional solenoid valve heat dissipation methods mostly rely on natural convection or simple heat sinks, which are difficult to meet the heat dissipation requirements. For this reason, we proposed a solenoid valve structure that uses a heat dissipation component composed of a fixed ring, a heat conduction plate, and a heat dissipation ring to quickly and effectively transfer the heat generated by the electromagnetic coil to the outside of the valve cover assembly.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] See also Figure 1-5The utility model provides a technical solution for the structure of an electromagnetic valve: a structure of an electromagnetic valve, including a valve body 1, a valve cover assembly 2, an electromagnetic coil 3, a heat dissipation assembly 4, a sealing plate 5, a valve core 6, a spring 8, a moving iron core 7 and a fixed iron core 9. Specifically, a flow channel 10, a flow channel 2 11 and a connecting hole 12 are arranged inside the valve body 1, and the valve core 6 is located directly above the connecting hole 12. When the valve core 6 is lowered, the connecting hole 12 is blocked, thereby closing the flow channel 10 and the flow channel 2 11; when the electromagnetic coil 3 is energized, an electromagnetic force is generated, so that the moving iron core 7 overcomes the spring force and moves upward, driving the valve core 6 to move upward, so that the flow channel 10, the flow channel 2 11 and the connecting hole 12 are closed. When the electromagnetic valve is in a connected state, the solenoid valve is in an open state. When the electromagnetic coil 3 is powered off, the electromagnetic force disappears, and the spring 8 pushes the valve core 6 and the moving iron core 7 to move downward. The valve core 6 blocks the connecting hole 12, thereby separating the flow channel 10 and the flow channel 2 11, and the solenoid valve is in a closed state. When the solenoid valve is in an open state, the heat generated by the continuous operation of the electromagnetic coil 3 is transferred to the outside of the valve cover assembly 2 through the heat dissipation component 4, and the external gas takes away the heat on the heat dissipation component 4 when flowing, thereby achieving the heat dissipation effect. A sealing structure is arranged between the valve cover assembly 2 and the heat dissipation component 4, as well as between the sealing plate 5 and the heat dissipation component 4, to ensure the good sealing of the solenoid valve during operation.

[0037] The valve cover assembly 2 includes a valve cover 21 , an inner ring column 22 , an outer ring column 23 and fixing strips 24 . Specifically, the lower part of the sealing plate 5 is located on the upper part of the multiple groups of fixing strips 24 , and the moving iron core 7 and the fixed iron core 9 are both located inside the inner ring column 22 .

[0038] The heat dissipation assembly 4 includes a fixed ring 41, a heat conducting plate 42 and a heat dissipation ring 43. Specifically, the multiple sets of heat conducting plates 42 transfer the heat generated by the electromagnetic coil 3 to the fixed ring 41 and the multiple sets of heat dissipation rings 43, and the multiple sets of heat dissipation rings 43 are arranged horizontally, so that when the airflow passes through, it is easy to carry away the heat.

[0039] In actual use, the solenoid valve structure generates electromagnetic force when the electromagnetic coil 3 is energized, causing the moving iron core 7 to move upward to overcome the spring force, driving the valve core 6 to move upward, and the solenoid valve is in an open state. When the electromagnetic coil 3 is de-energized, the electromagnetic force disappears, and the spring 8 pushes the valve core 6 and the moving iron core 7 to move downward. The valve core 6 blocks the connecting hole 12, and the solenoid valve is in a closed state. When the solenoid valve is opened, the heat generated by the continuous operation of the electromagnetic coil 3 is transferred to the outside of the valve cover assembly 2 through the heat dissipation assembly 4, and the external gas takes away the heat from the heat dissipation assembly 4 when flowing.
