Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic pilot heads, in particular to a hexagonal stainless steel high-pressure pilot head for a solenoid valve. Background Art

[0002] The electromagnetic pilot head, as one of the core components of the solenoid valve, plays an important role in controlling the flow of gas and liquid. The electromagnetic pilot head can help control parameters such as the direction or pressure of gas or liquid flow, thereby achieving efficient control of the hydraulic system; its control principle mainly relies on the magnetic field generated by the action of the electromagnet to control the actuated valve. When current passes through, the tripping mechanism in the electromagnetic pilot head is attracted by the magnetic force of the electromagnet, thereby conducting the downstream oil circuit.

[0003] In traditional processes, valves, as pipe components that regulate fluid flow, bear the heavy responsibility of opening and closing, ensuring the smooth flow of fluids along predetermined paths. However, with the advancement of technology and the continuous upgrading of industrial needs, traditional valves are struggling to meet certain modern challenges. First, in terms of response speed, traditional valves are limited by the complexity of their mechanical structure and the efficiency of their transmission mechanism, and often have difficulty responding quickly to high-precision or fast-switching operating instructions. In scenarios requiring instant feedback and precise control, this lag can lead to reduced system performance and even affect production efficiency and product quality. Second, in terms of durability and sealing performance, traditional valves operating in high-pressure, high-temperature, or corrosive environments for a long time face severe challenges with their seals. Over time, seals may wear out due to frequent friction, lose their original performance due to material aging, or become unable to effectively seal due to structural deformation. These factors work together to make traditional valves prone to leakage after long-term use, which not only wastes precious resources but also poses a threat to the environment and production safety.

[0004] In view of the above problems, the utility model provides a hexagonal stainless steel high-pressure pilot head of a solenoid valve. Utility Model Content

[0018] A solenoid valve hexagonal stainless steel high-pressure pilot head, including a static iron core 1, a sleeve 2 is provided on the surface of the static iron core 1, a moving iron core 4 is provided in the inner cavity of the sleeve 2 at the bottom of the static iron core 1, an aluminum valve seat 9 is fixedly connected to the bottom of the sleeve 2, a plastic plug 5 is embedded in the bottom of the inner cavity of the moving iron core 4, and a linkage groove 14 is provided on both sides of the aluminum valve seat 9. The two opposite sides of the two linkage grooves 14 are respectively provided with a channel 12 and a channel 2 13. The linkage groove 14 on the left side is connected to the channel 12. The linkage groove 14 on the right is connected to the channel 2 13, and the channel 1 12 and the channel 2 13 are both connected to the inner cavity of the aluminum valve seat 9. Both sides of the bottom of the moving iron core 4 are fixedly connected with the plastic bracket 8, and the bottom of the plastic bracket 8 extends to the inner cavity of the aluminum valve seat 9, and the inner cavity of the aluminum valve seat 9 is provided with a large plug 7, and both sides of the large plug 7 are fixedly connected to the plastic bracket 8. The bottom of the large plug 7 is fixedly connected to the inner spring 6, and the bottom end of the inner spring 6 is fixedly connected to the convex gasket 10.

[0019] An O-ring 3 is sleeved on the surface of the sleeve 2. The surface of the O-ring 3 contacts the aluminum valve seat 9. The O-ring 3 is made of fluororubber. The setting of the O-ring 3 ensures the sealing between the moving iron core 4 and the aluminum valve seat 9 to prevent medium leakage. The fluororubber sealing ring can work in high temperature, high pressure and highly corrosive working environments.

[0020] The surface of the convex gasket 10 is sleeved with a retaining spring 11, and the surface of the retaining spring 11 contacts the aluminum valve seat 9. The retaining spring 11 is used to position the convex gasket 10 and maintain its stability during movement.

[0021] The inner wall of the linkage groove 14 is provided with an internal thread 15 , which facilitates the linkage groove 14 to be connected to an external pipe under the action of the internal thread 15 , and also facilitates the subsequent disassembly of the pipe.

[0022] A groove 16 is provided on the top of the surface of the static iron core 1 , and the inner wall of the groove 16 is smooth. The provision of the groove 16 facilitates the subsequent positioning and coordination of the static iron core 1 with other components.

[0023] Working principle: When the electromagnetic coil is not energized, the moving iron core 4 is in the initial position. At this time, the large plug 7 is located in the inner cavity of the aluminum valve seat 9, and the large plug 7 blocks the channel 1 12 and the channel 2 13, thereby sealing the channel 1 12 and the channel 2 13 to prevent the flow of medium; when the electromagnetic coil is energized, the magnetic field generated by the static iron core 1 attracts the moving iron core 4 to move. When the moving iron core 4 moves, it drives the plastic plug 5 and the plastic bracket 8 to move downward. The plastic bracket 8 drives the large plug 7 to move downward and squeezes the inner spring 6. If the moving iron core When the core 4 moves downward a greater distance, the force exerted on the inner spring 6 will be greater, and the inner spring 6 may drive the convex gasket 10 to move downward. When the convex gasket 10 moves downward, the retaining spring 11 will expand. Through the setting of the retaining spring 11, the convex gasket 10 is stably positioned. When the large plug 7 moves away from channel 1 12 and channel 2 13, the passage is opened, and the fluid flows through channel 1 12, the inner cavity of the aluminum valve seat 9 and channel 2 13, thereby achieving the purpose of fluid flow.
