Description

Technical Field

[0001] This utility model relates to the field of solenoid valves, and in particular to a high-frequency response, high-flow-rate switching solenoid valve. Background Technology

[0002] High-frequency response high-flow-rate solenoid valves are automated components capable of rapidly responding to and controlling the flow of large-flow fluids. They are widely used in industrial automation and other fields. Their working principle is as follows: when the solenoid coil is energized, it generates electromagnetic force, causing the moving iron core to overcome the resistance of spring force and other forces, and attract with the stationary iron core, thereby opening the valve and allowing fluid to pass through. When the solenoid coil is de-energized, the electromagnetic force disappears, and the moving iron core returns to its original position under the action of spring force and other forces, closing the valve and blocking the fluid.

[0003] The flow rate directly affects the operation of a solenoid valve. If the flow rate far exceeds the upper limit of the valve diameter, it will cause local turbulence inside the valve, resulting in valve body vibration and noise. In severe cases, it may lead to seal failure and valve body cracking. When the actual flow rate is far lower than the rated value, the valve's flow efficiency is low and may not be able to meet the fluid supply requirements of the working conditions, causing the entire system to malfunction. Utility Model Content

[0004] In view of this, the present invention provides a high-frequency response, high-flow-rate switching solenoid valve, the main technical problem to be solved is: to change the flow rate through the solenoid valve by changing the diameter of the solenoid valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-frequency response, high-flow-rate switching solenoid valve, comprising a housing, a valve body fixedly connected inside the housing, a through hole in the middle of the valve body, a mounting post fixedly connected to the inner bottom of the housing, a rotating hole on the outer surface of the housing, the rotating hole being located below the mounting post, a threaded post threadedly connected inside the mounting post, a rubber block fixedly connected to the top of the threaded post, a connecting hole on the top of the rubber block, and a discharge hole on the outer surface of the rubber block, wherein there are multiple discharge holes, and the multiple discharge holes are connected to the connecting hole.

[0006] By adopting the above technical solution, during use, a screwdriver or other tool is passed through the rotating hole to rotate the threaded column, thereby controlling the threaded column to move up and down and adjust the position of the rubber block. When the rubber block is at the bottom, the entire through hole is opened, allowing the passage of large flow fluids. As the rubber block gradually moves upward, the discharge hole on the rubber block is gradually sealed, thereby gradually reducing the valve body's diameter, allowing the passage of medium and small flow fluids. This enables the solenoid valve to be adjusted according to the flow rate, making it suitable for different working scenarios.

[0007] As a further description of the above technical solution:

[0008] A fixing ring is fixedly connected to the lower surface of the valve body. The fixing ring is located below the through hole, and the outer surface of the rubber block is in contact with the inner surface of the fixing ring.

[0009] By adopting the above technical solution, the cooperation between the fixing ring and the rubber block can reduce the leakage of liquid from the gap between the fixing ring and the side of the rubber block, which is beneficial to improving the accuracy of the solenoid valve's diameter adjustment.

[0010] As a further description of the above technical solution:

[0011] A protective shell is fixedly connected to the top of the outer shell, and an electromagnetic coil is fixedly connected inside the protective shell.

[0012] By adopting the above technical solution, the iron core can be controlled to move up and down by energizing the electromagnetic coil.

[0013] As a further description of the above technical solution:

[0014] An iron core is movably connected inside the protective shell, and a piston is fixedly connected to the bottom of the iron core. The piston is located inside the shell and directly above the through hole.

[0015] By adopting the above technical solution, the piston moves up and down by moving the iron core. When the piston moves down to the through hole, it can seal the through hole and close the valve body. When the piston moves up away from the through hole, it can open the through hole and open the valve body.

[0016] As a further description of the above technical solution:

[0017] A spring is provided above the piston, and the spring is sleeved on the iron core.

[0018] By adopting the above technical solution, when the electromagnetic coil is de-energized, the electromagnetic force disappears, and the iron core resets under the action of spring force, etc., closing the valve and blocking the fluid.

[0019] As a further description of the above technical solution:

[0020] A junction box is fixedly connected to the outer surface of the protective shell, and the junction box is electrically connected to the electromagnetic coil.

[0021] By adopting the above technical solution, the electromagnetic coil can be powered through the junction box. At the same time, the junction box facilitates the connection between the solenoid valve and the external control circuit, making it easier to integrate the entire solenoid valve system into the automated control process.

[0022] By employing the above technical solution, the high-frequency response, high-flow-rate switching solenoid valve of this utility model has at least the following beneficial effects:

[0023] 1. Compared with the prior art, this high-frequency response high-flow-rate switching solenoid valve can change the flow rate within the solenoid valve by adjusting the valve's diameter. This allows the solenoid valve to be used not only for high-flow-rate liquids but also for medium- to low-flow-rate liquids. By rotating the threaded column, the position of the rubber block can be precisely controlled, thereby changing the connection between the discharge hole and the through hole, thus achieving precise flow control.

[0030] Reference Figure 1-4 This utility model provides a high-frequency response, high-flow-rate solenoid valve, comprising a housing 1, a valve body 2 fixedly connected inside the housing 1, a through hole 3 in the middle of the valve body 2, a mounting post 5 fixedly connected to the inner bottom of the housing 1, a rotating hole on the outer surface of the housing 1 located below the mounting post 5, a threaded post 6 threadedly connected inside the mounting post 5, a rubber block 7 fixedly connected to the top of the threaded post 6, a connecting hole 8 on the top of the rubber block 7, and multiple discharge holes 9 on the outer surface of the rubber block 7. Connected to the connecting hole 8, during use, a screwdriver or other tool is passed through the rotating hole to rotate the threaded post 6, thereby controlling the threaded post 6 to move up and down and adjust the position of the rubber block 7. When the rubber block 7 is at the bottom, the entire through hole 3 is opened, which can be used for the passage of large flow fluids. As the rubber block 7 moves upward, the discharge hole 9 on the rubber block 7 is gradually sealed, thereby gradually reducing the through diameter of the valve body 2, which can be used for the passage of medium and small flow fluids. This allows the solenoid valve to be adjusted according to the flow rate, making it suitable for different working scenarios.

[0031] A fixing ring 4 is fixedly connected to the lower surface of the valve body 2. The fixing ring 4 is located below the through hole 3. The outer surface of the rubber block 7 is in contact with the inner surface of the fixing ring 4. Through the cooperation between the fixing ring 4 and the rubber block 7, the liquid can be reduced from flowing out from the gap between the fixing ring 4 and the side of the rubber block 7, which is beneficial to improving the accuracy of the solenoid valve diameter adjustment.

[0032] A protective shell 10 is fixedly connected to the top of the outer shell 1. An electromagnetic coil 14 is fixedly connected inside the protective shell 10. When the electromagnetic coil 14 is energized, it can control the iron core 11 to move up and down. The iron core 11 is movably connected inside the protective shell 10. A piston 12 is fixedly connected to the bottom of the iron core 11. The piston 12 is located inside the outer shell 1 and is directly above the through hole 3. The up and down movement of the iron core 11 controls the up and down movement of the piston 12. When the piston 12 moves down to the through hole 3, it can seal the through hole 3 and close the valve body 2. When the piston 12 moves up away from the through hole 3, it can open the through hole 3 and open the valve body 2. A spring 13 is set above the piston 12 and is sleeved on the iron core 11. When the electromagnetic coil 14 is de-energized, the electromagnetic force disappears, and the iron core 11 is reset under the action of the spring force, closing the valve 2 and blocking the fluid.

[0033] A junction box 15 is fixedly connected to the outer surface of the protective shell 10. The junction box 15 is electrically connected to the electromagnetic coil 14. The electromagnetic coil 14 can be powered through the junction box 15. At the same time, the junction box 15 facilitates the connection between the solenoid valve and the external control circuit, making it easier to integrate the entire solenoid valve system into the automated control process.

[0034] Working Principle: In actual operation, when the solenoid valve needs to be opened to allow a large flow of fluid, first insert a screwdriver or similar tool through the rotating hole on the outer casing, rotate the threaded column to move it downwards, causing the rubber block to move downwards to its lowest position. At this point, the discharge hole on the rubber block is fully connected to the through hole, and the entire through hole is in its fully open state, ensuring the smooth passage of a large flow of fluid. Simultaneously, energizing the solenoid coil through the junction box generates electromagnetic force, causing the iron core to move upwards. The iron core then drives the piston upwards, fully opening the through hole and ensuring the valve body is fully open, allowing fluid to pass through the through hole without obstruction.

[0035] When adjusting the flow rate of the solenoid valve to a small or medium flow rate, use a screwdriver or similar tool to rotate the threaded post through the rotating hole, causing the threaded post to move upwards, which in turn moves the rubber block upwards. As the rubber block rises, its discharge hole is gradually sealed by the retaining ring, thereby gradually reducing the valve body's diameter and consequently decreasing the fluid flow rate. During this process, the solenoid coil remains energized, and the positions of the iron core and piston remain unchanged to ensure the valve body is in a basically open state.

[0036] When it is necessary to completely close the solenoid valve and block the fluid, the power supply to the solenoid coil is cut off through the junction box. The electromagnetic force disappears, and the iron core moves downward under the action of the spring force, which drives the piston to move downward to seal the through hole. At the same time, if the rubber block was not in the position of completely sealing the through hole at the top before, the threaded column can be rotated to make the rubber block rise to the top to ensure that the through hole is completely sealed, thereby completely blocking the passage of fluid.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
