Description

Technical Field

[0001] This utility model relates to the technical field of solenoid valve structures, and in particular to a solenoid valve structure that enhances the high-pressure opening capability of the valve body. Background Technology

[0002] Various types of solenoid valves are frequently used in thermal management systems to control and regulate fluid media. Common solenoid valves include a valve seat, valve core, valve cover assembly, return spring, moving iron core, stationary iron core, and coil assembly. Air enters through a side port on the valve seat and exits through a lower port.

[0003] In high-pressure systems, the proper opening and closing of solenoid valves is crucial for reliable system operation. If a solenoid valve fails to open smoothly under high pressure, it may lead to excessive system pressure, causing equipment damage, leaks, and other safety accidents. Therefore, improving the high-pressure opening capability of solenoid valves can ensure their reliable operation under various working conditions, thereby enhancing the safety and stability of the entire system. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a solenoid valve structure that enhances the high-pressure valve opening capability of the valve body by strengthening the electromagnetic force of the coil, thereby enabling the valve body to obtain a greater valve opening capability under the same pressure and output voltage.

[0005] This utility model discloses a solenoid valve structure for enhancing the high-pressure opening capability of a valve body. The structure includes a coil assembly, a valve cover assembly, a fully enclosed piston, a sealing ring, a valve seat, and a valve core. Multiple air inlets are provided on the lower part of the outer wall of the valve seat, and an air outlet is provided at the bottom of the valve seat. A first chamber is provided inside the valve seat, and the valve core is vertically movable within this first chamber. The fully enclosed piston and the sealing ring are respectively disposed on the outer wall of the valve core. The valve cover assembly is mounted on the top of the valve seat, and the valve cover assembly and the valve core cooperate to form a second chamber. A coil assembly is located at the top of the valve cover assembly, and the coil assembly is used to generate a magnetic field to drive the valve core. The valve core moves up and down; the valve body is normally closed. Under normal conditions, the sealing ring on the side of the valve core blocks the air outlet of the valve seat. When it needs to be opened, the coil assembly is energized to generate a magnetic field. The components inside the coil assembly move in coordination to generate air pressure. The air pressure and elastic force push the valve core upward, and the sealing ring on the side of the valve core separates from the air outlet. When it is not in use, the coil assembly is de-energized and the electromagnetic force disappears. The components inside the coil assembly push the valve core downward, so that the sealing ring on the side of the valve core blocks the air outlet, allowing the valve body to obtain a greater valve opening capacity under the same pressure and output voltage.

[0006] Preferably, the coil assembly includes a fixed component, a stationary iron core buffer pad, a stationary iron core, a moving iron core, and a moving iron core buffer pad. The stationary iron core and the moving iron core are installed inside the coil assembly. The top of the moving iron core is frustum-shaped, and the bottom of the stationary iron core has a frustum-shaped hole that mates with the moving iron core. A stationary iron core buffer pad is provided at the bottom of the stationary iron core. The top of the stationary iron core is mounted on the coil assembly via the fixed component. A groove is provided at the bottom of the moving iron core, and the moving iron core buffer pad is disposed within the groove at the bottom of the moving iron core. The valve body is normally in a closed state, and the valve core side sealing ring seals the outlet. For the air vent, the moving iron core buffer pad at the lower end of the moving iron core seals the upper port of the pressure relief hole. When it needs to be opened, the coil assembly is energized to generate a magnetic field, causing the moving iron core to move upward. The moving iron core buffer pad at the lower end of the moving iron core separates from the upper port of the pressure relief hole. The air pressure and elastic force force the valve core to move upward, and the sealing ring on the side of the valve core separates from the air outlet. When it is not in use, the coil assembly is de-energized, the moving iron core moves downward, the moving iron core buffer pad at the lower end of the moving iron core blocks the upper port of the pressure relief hole, and at the same time, the moving iron core moves downward with the valve core, and the sealing ring on the side of the valve core blocks the air outlet.

[0007] Preferably, the coil assembly consists of a coil frame, a coil winding, an injection-molded shell, a coil yoke, and a reinforcing ring. The coil winding is covered by the coil frame, and the two are wrapped by the injection-molded shell. The coil yoke is mounted on the outside of the injection-molded shell. The reinforcing ring is set on the outer wall of the coil frame, and the stationary iron core and the moving iron core are set inside the coil frame.

[0008] Preferably, the fixing component includes a screw, and the top of the stationary iron core is provided with a threaded hole. The screw passes through the top of the coil assembly and is fitted into the threaded hole, thereby improving the convenience and firmness of fixing the stationary iron core.

[0009] Preferably, the valve cover assembly and the valve seat are connected by pressure welding; this improves the stability of the installation and the ease of processing.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the valve body is normally closed. Under normal conditions, the sealing ring on the side of the valve core blocks the air outlet of the valve seat. When it needs to be opened, the coil assembly is energized to generate a magnetic field. The components inside the coil assembly move in coordination to generate air pressure. The air pressure and elastic force push the valve core upward, and the sealing ring on the side of the valve core separates from the air outlet. When it is not needed, the electromagnetic force of the coil assembly disappears, and the components inside the coil assembly push the valve core downward, so that the sealing ring on the side of the valve core blocks the air outlet, so that the valve body can obtain a greater valve opening capacity under the same pressure and output voltage.

In this embodiment, the valve body is normally closed. Under normal conditions, the sealing ring 7 on the side of the valve core 10 blocks the air outlet of the valve seat 9. When it needs to be opened, the coil assembly 1 is energized to generate a magnetic field. The components inside the coil assembly 1 move in coordination to generate air pressure. The air pressure and elastic force push the valve core 10 upward, and the sealing ring 7 on the side of the valve core 10 separates from the air outlet. When it is not needed, the electromagnetic force of the coil assembly 1 disappears, and the components inside the coil assembly 1 push the valve core 10 downward, so that the sealing ring 7 on the side of the valve core 10 blocks the air outlet, so that the valve body can obtain a greater valve opening capacity under the same pressure and output voltage.

[0015] Example 2 Based on Example 1, such as Figure 1 As shown, the present invention provides a solenoid valve structure for improving the high-pressure valve opening capability of the valve body.

The sealing ring 7 on the side of the valve core 10 seals the air outlet, and the moving iron core buffer pad 8 at the lower end of the moving iron core 4 seals the upper port of the pressure relief hole. When it needs to be opened, the coil assembly 1 is energized to generate a magnetic field, causing the moving iron core 4 to move upward.

The air pressure and elastic force force the valve core 10 to move upward, and the sealing ring 7 on the side of the valve core 10 separates from the air outlet. When it is not needed, the coil assembly 1 is de-energized, the moving iron core 4 moves downward, and the moving iron core buffer pad 8 at the lower end of the moving iron core 4 blocks the upper port of the pressure relief hole. At the same time, the moving iron core 4 moves downward with the valve core 10, and the sealing ring 7 on the side of the valve core 10 blocks the air outlet.
