Description

Technical Field

[0001] This utility model relates to the field of solenoid valve technology, and in particular to a high-sealing adjustable solenoid valve. Background Technology

[0002] Solenoid valves are fundamental components for automatic flow control. They control the valve core position via an electromagnetic coil, cutting off or connecting the air supply to change the direction of fluid flow, thereby controlling the flow direction and flow rate of the medium. In the mechanical field, solenoid valves are widely used and crucial; as key components in automated control systems, they play an irreplaceable role in many aspects.

[0003] Currently, some traditional solenoid valves cannot meet production requirements, as they are prone to leakage at the valve plate when closed, resulting in poor sealing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-sealing adjustable solenoid valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-sealing adjustable solenoid valve includes a valve body, a control chamber in the middle of the valve body, the control chamber being connected to a fluid inlet and a fluid outlet respectively, and a valve plate inside the control chamber for controlling the flow of fluid.

[0007] An electromagnetic control module is installed on the upper part of the valve body. The electromagnetic control module controls the movement of the valve plate through an electromagnet. A convex ring is provided on the outer side of the valve plate, and the valve plate is tightly fitted to the outer wall of the fluid outlet in the closed state.

[0008] The upper wall of the fluid outlet is provided with a squeezing block. When the squeezing block contacts the valve plate, it moves downward. The bottom of the squeezing block is provided with a squeezing ring, and a flexible ring is provided on the side away from the squeezing ring. The flexible ring is deformed by the movement of the squeezing ring.

[0009] Furthermore, in a preferred configuration, an electromagnet is installed in the middle of the electromagnetic control module, the electromagnet is electrically connected to the control circuit board, one side of the electromagnet is connected to the moving iron core via a reset spring, and the moving iron core is connected to the valve plate.

[0010] In addition, a preferred structure is that the inner upper wall of the fluid outlet is provided with a rubber sleeve, which covers the flexible ring and the outer wall of the extrusion block.

[0011] In addition, a preferred structure is that a rubber diaphragm is connected to the outer wall of the valve plate, and the other end of the rubber diaphragm is connected to the inner wall of the control cavity.

[0012] In addition, a preferred structure is that the bottom wall of the extrusion block is connected to an extrusion ring, and the bottom of the extrusion ring is connected to a spring, which guides the extrusion ring to move up and down.

[0013] Furthermore, in a preferred configuration, the flexible ring is disposed on the outer wall of the fluid outlet, and the outer wall of the fluid outlet has a slot to allow for the flexible ring to move. Several movable plates are installed on the inner side of the flexible ring, and the movable plates are staggered with the extrusion ring. When the extrusion ring moves downward, the extrusion ring and the ends of the movable plates are pressed into contact.

[0014] In addition, a preferred structure is that the bottom wall of the convex ring is provided with an inclined boss, which fits snugly against the flexible ring.

[0015] In addition, a preferred structure is that the bottom wall of the valve plate is provided with an annular groove, the annular groove fits the extrusion block, and drainage holes are provided on both sides of the inner wall of the annular groove.

[0016] The beneficial effects of this utility model are as follows:

[0017] In this invention, the flexible ring is deformed by the compression ring as the valve plate closes, and the rubber sleeve is tightly fitted to the protruding ring at the bottom of the valve plate, improving the tightness of contact with the compression ring and enhancing the sealing performance between the two.

[0018] Meanwhile, the rubber diaphragm is connected to the valve plate to improve the sealing performance when the valve plate moves, ensuring the sealing performance inside the control chamber.

[0019] A rubber sleeve is installed on the upper inner wall of the fluid outlet. The rubber sleeve wraps around the upper wall of the flexible ring and the extrusion block to ensure the sealing performance of both, ensuring absolute sealing during their movement, and further improving the overall sealing performance of the valve body.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-4 A high-sealing adjustable solenoid valve includes a valve body 1, a control chamber 10 is provided in the middle of the valve body 1, the control chamber 10 is connected to the fluid inlet 3 and the fluid outlet 4 respectively, and a valve plate 9 is provided inside the control chamber 10, which is used to control the flow of fluid.

[0027] Furthermore, an electromagnetic control module 2 is installed on the upper part of the valve body 1. The electromagnetic control module 2 controls the movement of the valve plate 9 through the electromagnet 6. A convex ring 11 is provided on the outer side of the valve plate 9, and the valve plate 9 is tightly fitted onto the outer wall of the fluid outlet 4 in the closed state.

[0028] Furthermore, the upper wall of the fluid outlet 4 is provided with a squeezing block 15. When the squeezing block 15 contacts the valve plate 9, it moves downward. The bottom of the squeezing block 15 is provided with a squeezing ring 16. A flexible ring 19 is provided on the side away from the squeezing ring 16. The flexible ring 19 deforms due to the movement of the squeezing ring 16. The flexible ring 19 deforms and expands outward, causing the bottom wall of the rubber sleeve 13 to bulge outward and make squeezing contact with the inner wall of the convex ring 11.

[0029] Furthermore, an electromagnet 6 is installed in the middle of the electromagnetic control module 2. The electromagnet is electrically connected to the control circuit board 21. One side of the electromagnet 6 is connected to the moving iron core 8 through a reset spring 7. The moving iron core 8 is connected to the valve plate 9.

[0030] Furthermore, a rubber sleeve 13 is provided on the inner upper wall of the fluid outlet 4, and the rubber sleeve 13 covers the outer wall of the flexible ring 19 and the extrusion block 15.

[0031] Furthermore, a rubber diaphragm 5 is connected to the outer wall of the valve plate 9, and the other end of the rubber diaphragm 5 is connected to the inner wall of the control cavity 10. The rubber diaphragm 5 forms a sealed cavity in the control cavity 10 to ensure sealing performance.

[0032] Furthermore, an extrusion ring 16 is connected to the bottom wall of the extrusion block 15, and a spring 17 is connected to the bottom of the extrusion ring 16, which guides the extrusion ring 16 to move up and down.

[0033] Furthermore, a flexible ring 19 is disposed on the outer wall of the fluid outlet 4, and a slot is provided on the outer wall of the fluid outlet 4 to allow the flexible ring 19 to deform and move. Several movable pieces 18 are installed on the inner side of the flexible ring 19. The movable pieces 18 are staggered with the extrusion ring 16, and when the extrusion ring 16 moves downward, the extrusion ring 16 and the ends of the movable pieces 18 are pressed into contact.

[0034] Furthermore, the bottom wall of the convex ring 11 is provided with an inclined boss 12, which fits snugly against the flexible ring 19.

[0035] Furthermore, the bottom wall of the valve plate 9 is provided with an annular groove, which fits the extrusion block 15, and drainage holes 14 are provided on both sides of the inner wall of the annular groove.

[0036] In this embodiment, the electromagnetic control module 2 is controlled by the control circuit board 21. It generates different currents to make the electromagnet 6 produce different electromagnetic attraction forces, thereby controlling and adjusting the moving iron core. The attraction force generated by the electromagnet 6 drives the valve plate 9 to move upward. At this time, the control cavity 10 is circulated, and the fluid inlet 3, the fluid outlet 4, and the control cavity 10 are connected.

[0037] When the electromagnet is de-energized, the valve plate 9 is pressed against the upper opening of the fluid outlet 4 by the return spring 7. At this time, the valve plate 9 is in contact with the extrusion block 15. The extrusion block 15 is subjected to force and moves downward, driving the extrusion ring 16 downward. The extrusion ring 15 extrudes the moving piece 18 so that the flexible ring 19 deforms and expands outward. At this time, the bottom of the rubber sleeve 13 has an annular protrusion and fits with the inclined protrusion 12 on the bottom wall of the protrusion ring 11 to ensure sealing.

[0038] After the valve is closed, some of the fluid that is not discharged in time escapes through the gap between the rubber sleeve 13 and the valve plate 9 into the drainage hole 14 for temporary storage, and flows out when the valve plate 9 is opened again.

[0039] The rubber diaphragm 5 has a certain degree of flexibility to allow the valve plate 9 to move while ensuring a tight seal.

[0040] It is worth noting that the specific operating principles of the control circuit board 21 and the electromagnet 6 are common knowledge to those skilled in the art and will not be explained further.

[0041] It is worth noting that the flexible ring 19 has good flexibility, can deform under force and can self-reset. Its specific materials and principles are existing technologies and will not be explained further.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
