Description

Technical Field

[0001] The invention relates to the technical field of electromagnetic valves, in particular to an electromagnetic valve device capable of eliminating negative pressure in a valve. Background Art

[0002] Solenoid valves are electromagnetically controlled industrial devices, essential automation components for controlling fluids. They are classified as actuators, not limited to hydraulic or pneumatic systems. They are used in industrial control systems to adjust the direction, flow, speed, and other parameters of media. Solenoid valves can be combined with various circuits to achieve desired control, ensuring both precision and flexibility. There are many different types of solenoid valves, each serving different functions within a control system. The most commonly used are check valves, safety valves, directional control valves, and speed control valves.

[0003] When the solenoid valve is used in practice, if it is closed quickly, the downstream fluid will continue to flow forward due to inertia, resulting in the formation of a "vacuum zone" inside the valve and in the local space downstream, causing a certain negative pressure in the downstream pipeline of the solenoid valve. If the downstream pipeline is long or the flow rate is high, the inertia effect is more significant and the negative pressure is more obvious.

[0004] However, when the existing solenoid valve responds quickly to closing, it is difficult to quickly replenish the "vacuum zone" formed in the local space downstream of the valve, and it is not convenient to eliminate the negative pressure in the valve and the downstream pipeline. The negative pressure in the valve will affect the sealing performance of the solenoid valve during use and the actual service life of the components. In addition, the solenoid valve cannot automatically remove internal impurities when switching. The accumulation of impurities at the valve port can easily cause a linkage effect, further aggravating the negative pressure and other problems, affecting the actual use of the solenoid valve. Therefore, those skilled in the art provide a solenoid valve device that can eliminate the negative pressure in the valve to solve the problems raised in the above background technology. Summary of the Invention

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figures 1 to 8 In an embodiment of the present invention, an electromagnetic valve device that can eliminate negative pressure in a valve includes a valve body 10, a boosting box 40, an absorption component 60, etc. A baffle 11 for separating upper and lower flow channels is fixedly installed inside the valve body 10, and a valve port 12 is provided on the baffle 11. A filter component 20 that can abut against the valve port 12 is provided at the bottom of the valve body 10. An electromagnetic component 30 is fixedly installed on the top of the valve body 10. The electromagnetic component 30 is used to control the synchronous lifting and lowering of a piston 13 and the filter component 20 that are adapted to the valve port 12. The boosting box 40 is fixedly installed at the bottom of the valve body 10. An absorption hole 14 is connected between the top of the boosting box 40 and the upstream flow channel in the valve body 10. A one-way valve 50 is connected between the boosting box 40 and the downstream flow channel in the valve body 10. The one-way valve 50 is used to control the fluid from the boosting box 40 to the downstream flow channel in the valve body 10.

[0039] Among them, the absorption component 60 is rotatably installed inside the booster box 40, the absorption component 60 includes an impeller, the top of the absorption component 60 is slidably connected to a cleaning component 70 that penetrates the absorption hole 14 and abuts against the bottom of the filter component 20, and the electromagnetic component 30 is connected to a push-pull component 80 extending to the bottom of the inner cavity of the booster box 40. The push-pull component 80 is used to control the rotation of the absorption component 60 and the cleaning component 70.

[0040] When the solenoid valve device is actually used, the two ends of the valve body 10 are assembled to the corresponding pipelines or components through flange connections. The solenoid assembly 30 is opened to drive the piston 13 and the filter assembly 20 connected to it to move upward, and the fluid can flow from the valve port 12 inside the valve body 10. When the valve port 12 is fully opened, the filter assembly 20 blocks the bottom of the valve port 12, thereby filtering the fluid passing through the valve port 12 to avoid impurities clogging the valve port 12 and affecting the sealing of the solenoid valve when it is closed. When the solenoid valve is opened or closed, the absorption assembly 60 can exert a certain suction or thrust on the piston 13, thereby accelerating the response of the solenoid valve.

[0041] When the solenoid valve is closed, the piston 13 and the filter assembly 20 move downward. The movement of the piston 13 can drive the absorption assembly 60 and the cleaning assembly 70 connected to its top to rotate through the push-pull assembly 80. The cleaning assembly 70 rotates in contact with the bottom surface of the filter assembly 20, which can remove impurities attached to the outside of the filter assembly 20. When the filter assembly 20 moves downward, the cleaning assembly 70 can be compressed so that it slides on the top of the absorption assembly 60. The absorption assembly 60 can provide a certain elastic support for the up and down movement of the cleaning assembly 70, so that the cleaning assembly 70 is in close contact with the filter assembly 20 when the valve is opened and closed. The absorption assembly 60 rotating inside the booster box 40 can generate a certain suction force, which is convenient for absorbing impurities directly above the booster box 40 into its interior. The absorption assembly 60 can also increase the pressure inside the booster box 40, so that the fluid inside the booster box 40 can be quickly transported to the interior of the flow channel below the valve body 10 through the one-way valve 50 when the valve is closed, thereby effectively eliminating the negative pressure generated inside the valve body 10 when it is opened and closed.

[0042] In one embodiment, see Figures 1 to 5 Specifically, the booster box 40 includes an absorption tube 401 whose top extends into the interior of the valve body 10 and a pressure balancing box 402 fixedly installed at the bottom of the valve body 10. The top of the absorption tube 401 is integrally formed with an absorption hopper 403 with an absorption hole 14 in the center. The bottom end of the absorption tube 401 is connected to the diversion chamber 15 in the pressure balancing box 402 through an upwardly bent diversion tube 405. The diversion chamber 15 is connected to the downstream flow channel of the valve body 10 through a one-way valve 50. A partition chamber 16 for accommodating the push-pull assembly 80 is provided at the bottom of the inner cavity of the pressure balancing box 402. The push-pull assembly 80 can be smoothly displaced inside the partition chamber 16 to prevent impurities from affecting the normal use of the push-pull assembly 80. A drain pipe 404 connected to the diversion chamber 15 is provided on one side of the balancing box 402.

[0043] When the valve is closed, the rotating absorption component 60 can suck part of the fluid in the inner cavity of the valve body 10 into the interior of the absorption tube 401, and the absorption bucket 403 provided on the top of the absorption tube 401 facilitates efficient absorption and flow of the fluid. At the same time, when the valve is opened, it prevents a large amount of impurities in the absorption tube 401 from flowing back into the interior of the valve body 10. When the valve is fully opened or closed, it is also convenient to separate the absorption hole 14 at the center of the absorption bucket 403, which can facilitate the operator to use the sewage pipe 404 to clean the impurities inside the solenoid valve, ensuring that the valve body is clean during daily use. The inner cavity of 10 is disconnected from the inner cavity of the absorption tube 401. The pressure increase in the inner cavity of the absorption tube 401 can transport the liquid to the guide cavity 15 of the balance tank 402 through the guide tube 405. The pressure reduction in the lower flow channel in the boost valve body 10 in the guide cavity 15 can open the one-way valve 50, and the pressure balance between the guide cavity 15 and the lower flow channel in the valve body 10 can be achieved, thereby effectively eliminating the negative pressure generated in the lower flow channel in the valve body 10. The upward-bent guide tube 405 can prevent the dirt in the inner cavity of the guide cavity 15 from being drained into the interior of the absorption tube 401 when the valve is closed.

[0044] See Figures 1 to 7 Specifically, the absorption component 60 includes a rotating rod 601 rotatably installed inside the pressure balance box 402. The rotating rod 601 and the balance box 402 can be sealed and rotatably connected to ensure the sealing of the interior of the separation chamber 16. The rotating rod 601 extends to the top of the absorption tube 401 and is fixedly installed with a first impeller 602. The top center of the first impeller 602 is connected to the cleaning component 70 through a fixedly installed first spring 603 and a cross rod 604. The top of the cross rod 604 slides and extends to the interior of the cleaning component 70. When the solenoid valve is switched, the rotating rod 601 can be directly driven to rotate by the push-pull component 80. The rotating rod 601 drives the first impeller 602, the cross rod 604 and the first spring 603 to rotate inside the absorption tube 401. The cross rod 604 facilitates the rotation of the cleaning component 70 connected thereto. The first spring 603 can provide elastic support for the cleaning component 70. When the valve is closed, the rotation of the first impeller 602 can generate suction to the inside of the absorption tube 401.

[0045] Correspondingly, the filter assembly 20 includes a vertical rod 201 connected to the center of the piston 13. The bottom end of the vertical rod 201 is fixedly installed with a filter bucket 202 that abuts the bottom of the valve port 12. The vertical rod 201 facilitates a stable connection between the filter bucket 202 and the piston 13. The piston 13 can drive the filter bucket 202 to move up and down through the vertical rod 201. The spherical bottom surface of the filter bucket 202 abuts against the cleaning assembly 70. The filter bucket 202 facilitates filtering the fluid flowing through the valve port 12.

[0046] In detail, the cleaning assembly 70 includes a support rod 701 slidably connected to the cross rod 604, and the support rod 701 is located at the bottom outer ring of the absorption tube 401 and is fixedly installed with a second impeller 702, and the top of the support rod 701 is fixed with multiple groups of arc-shaped scraping strips 703 arranged equidistantly around the axis thereof, and the arc-shaped scraping strips 703 abut against the bottom surface of the filter bucket 202. When the cross rod 604 rotates, it can drive the support rod 701, the second impeller 702 and the scraping strips 703 to rotate, and the scraping strips 703 rotate in contact with the surface of the filter bucket 202 to effectively remove impurities on the surface of the filter bucket 202, thereby ensuring the stable flow of fluid inside the solenoid valve during daily use, and the filter bucket 202 moves up and down with the elastic support provided by the first spring 603, so that the support rod 701, the second impeller 702 and the scraping strips 703 can move up and down with the filter bucket 202, and the second impeller 702 provided therein can improve the absorption effect of the inner cavity of the absorption tube 401.

[0047] Furthermore, a sealing gasket 17 is bonded to the top surface of the second impeller 702 for abutting the bottom of the absorption hole 14, and a sealing ring 18 is bonded to the outer ring of the connection between the support rod 701 and the scraper 703 for abutting the top of the absorption hole 14. During the switching process of the solenoid valve, the absorption hole 14 is in an open state. When it is fully opened or closed, the sealing gasket 17 or the sealing ring 18 will seal the absorption hole 14 respectively, which can ensure that the boosting box 40 of the solenoid valve is completely separated from the upstream channel of the inner cavity of the valve body 10 except during the switching process. The one-way valve 50 is used to separate the boosting box 40 from the downstream channel of the inner cavity of the valve body 10, so that the operator can remove impurities inside the boosting box 40.

[0048] On the basis of the above embodiment, specifically, the push-pull assembly 80 includes two groups of parallel rods 801 fixedly installed inside the separation chamber 16, T-shaped rods 802 are slidably installed on the two groups of rods 801, and a gear 803 is fixedly installed on the surface of the rotating rod 601 located inside the separation chamber 16. A rack 806 meshing with the gear 803 is provided on one side of the T-shaped rod 802, and the two symmetrical ends of the T-shaped rod 802 are connected to a sliding rod 804 through a hinged connecting rod 805. The sliding rod 804 is connected to the inside of the baffle 11 in an up and down sliding manner, and the sliding rod 804 extends to the top end inside the valve body 10 and is fixedly connected to the piston 13.

[0049] When the electromagnetic assembly 30 controls the piston 13 to move up and down, the piston 13 can move up and down through the sliding rod 804 that slides through the baffle 11. The baffle 11 can be sealed and slidably connected to the sliding rod 804. The moving sliding rod 804 can pull the T-rod 802 to slide on the frame rod 801 through the connecting rod 805. The T-rod 802 can drive the gear 803 and the rotating rod 601 to rotate through the rack 806 on its side, so that the rotating rod 601 drives the first impeller 602 and the second impeller 702 and other components to rotate. The push-pull assembly 80 components are all arranged inside the separation chamber 16, and their displacement is not easily affected by the fluid and impurities inside the valve body 10.

[0050] Among them, the electromagnetic assembly 30 includes an electromagnetic box 302 fixedly installed on the top of the valve body 10, and the interior of the electromagnetic box 302 is fixedly installed with a static iron core 301 located at the top of its inner cavity and a coil 304 with a moving iron core 303 at the center. A second spring 305 is connected between the moving iron core 303 and the static iron core 301, and the bottom end of the moving iron core 303 is fixedly connected to the center of the piston 13 through a round rod 306. A third spring 307 is installed between the top of the piston 13 and the bottom of the electromagnetic box 302.

[0051] The junction box arranged on the side of the electromagnetic box 302 is used to connect an external power supply, etc. When the solenoid valve is opened, the coil 304 and the static iron core 301 can pull the moving iron core 303 upward, and the moving iron core 303 drives the second spring 305 and the third spring 307 to be compressed and the round rod 306 and the piston 13 to move upward, thereby realizing the opening of the valve port 12 inside the solenoid valve. When the solenoid valve is closed, the second spring 305 and the third spring 307 are reset to drive the moving iron core 303, the piston 13 and other components to move downward, thereby realizing the closure of the valve port 12. The displacement of the piston 13 can drive the push-pull assembly 80 connected thereto to stabilize the displacement transmission.

[0052] In one embodiment, see Figures 2 to 5 or Figure 8 Specifically, the one-way valve 50 includes a connecting pipe 501 fixedly installed at the bottom of the valve body 10 and located inside the guide chamber 15. The interior of the connecting pipe 501 is connected to a blocking plate 503 through a fourth spring 502. The blocking plate 503 is used to block the through hole 19 at the bottom of the connecting pipe 501. Furthermore, the one-way valve 50 also includes a limit rod 504 slidably installed at the center of the connecting pipe 501. The limit rod 504 is located at the center of the fourth spring 502, and the bottom end of the limit rod 504 is fixedly connected to the center of the blocking plate 503. A filter plate 505 is fixedly installed at the bottom of the connecting pipe 501.

[0053] When the fluid pressure in the downstream channel of the valve body 10 is lower than the fluid pressure in the guide chamber 15, the pressure difference can control the sealing plate 503 to move upward inside the connecting pipe 501. The opening of the through hole 19 can replenish fluid into the downstream channel of the valve body 10, thereby eliminating the negative pressure in the valve. When the sealing plate 503 moves, it can drive the fourth spring 502 to expand and contract. The fourth spring 502 can press the sealing plate 503 when the one-way valve 50 stops being used, and is provided with a limit rod 504 that moves with the sealing plate 503. The limit rod 504 can improve the stability of the displacement of the sealing plate 503, etc., and the filter plate 505 provided can prevent impurities inside the booster box 40 from entering the interior of the connecting pipe 501.
