Description

Technical Field

[0001] This application relates to the field of solenoid valve technology, and in particular to a high-flow-rate inlet solenoid valve. Background Technology

[0002] Currently, the inlet solenoid valve is an automated device that uses electromagnetic control principles to control the flow of water in a pipeline, playing a crucial role in various systems requiring precise water intake control. By energizing or de-energizing the solenoid coil, the valve core is moved, thus opening or closing the valve and achieving precise control of the incoming water. When the solenoid coil is energized, an electromagnetic force attracts the valve core, opening the valve and allowing water to flow into the system.

[0003] However, the existing solenoid valve has the following drawbacks: for example, when the solenoid valve is activated, the diaphragm inside the solenoid valve rises, and the water flow can only pass through a small distance with a diameter that is only a small part of the diaphragm's rise. If the flow rate needs to be increased, a larger solenoid valve needs to be used, which reduces the practicality of the device. Summary of the Invention

[0004] The purpose of this application is to increase the flow rate of the solenoid valve without changing its size.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: It includes a main body comprising a solenoid valve tube. A connecting shell is fixedly connected to the upper surface of the solenoid valve tube. An energizing mechanism is installed on the inner wall of the connecting shell. The energizing mechanism includes a coil module. The upper surface of the coil module is fixedly connected to the inner wall of the connecting shell. A spring is fixedly connected to the lower surface of the coil module. A first magnetic block is fixedly connected to the end of the spring. A connecting seat is fixedly connected to the lower surface of the first magnetic block. An auxiliary mechanism is installed on the lower surface of the connecting seat. A sealing mechanism is installed on the lower surface of the auxiliary mechanism. The sealing mechanism includes a diaphragm, which is installed on the lower surface of the auxiliary mechanism. A rotating mechanism is installed on the inner wall of the solenoid valve tube. The rotating mechanism includes a rotating plate. A rotating shaft is fixedly connected inside the rotating plate. The surface of the rotating shaft is movably connected to the inner wall of the solenoid valve tube. A pull rod is movably connected to the upper surface of the rotating plate. The end of the pull rod is movably connected to the lower surface of the diaphragm. A first electromagnet is fixedly connected inside the rotating plate. A second electromagnet is fixedly connected to the inner wall of the solenoid valve tube.

[0006] As a preferred embodiment, a second magnetic block is fixedly connected to the upper surface of the connector, the second magnetic block being located to the right of the first magnetic block, and the auxiliary mechanism includes an elastic pressure diaphragm, the upper surface of which is fixedly connected to the lower surface of the connector.

[0007] As a preferred embodiment, a pressure ring is fixedly connected to the surface of the elastic pressure diaphragm, a cavity is formed inside the elastic pressure diaphragm, a compressed air bag is fixedly connected to the inner wall of the cavity, and a first protrusion is fixedly connected to the upper surface of the compressed air bag, the first protrusion being located below the pressure ring.

[0008] As a preferred embodiment, a flange is fixedly connected to the surface of the solenoid valve tube, and a first groove is formed on the surface of the solenoid valve tube. A fixing mechanism is installed on the surface of the first groove, and the fixing mechanism includes a sealing ring, the surface of which is in contact with the surface of the first groove.

[0009] As a preferred embodiment, a pressure block is fixedly connected to the surface of the sealing ring, and a bolt is installed on the surface of the pressure block, with the end of the bolt extending through the pressure block into the interior of the solenoid valve tube.

[0010] As a preferred embodiment, the upper surface of the rotating plate is provided with a second groove, and the lower surface of the diaphragm is fixedly connected with a second protrusion, the second protrusion being located inside the second groove.

[0011] As a preferred embodiment, a connecting plate is fixedly connected to the inner wall of the solenoid valve tube, and a third protrusion is fixedly connected to the lower surface of the diaphragm. The third protrusion is located inside the connecting plate, and the connecting plate is located on the right side of the rotating plate.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) During use, when the coil module is energized, the current between the first electromagnet and the second electromagnet is broken, attracting the first and second magnetic blocks upwards, causing the connecting seat to move upwards. The elastic pressure diaphragm fixed to the lower surface of the connecting seat can then pull the elastic diaphragm upwards, so that the lower surface of the diaphragm is no longer in contact with the upper surfaces of the connecting plate and the rotating plate, allowing water to flow through. At the same time, the pull rod movably connected to the lower surface of the diaphragm is pulled upwards, and one end of the rotating plate is subjected to an upward force, causing the rotating plate to rotate counterclockwise around the rotating shaft. This causes the diameter of the water flow inside the solenoid valve tube to change from the original... The diaphragm rises a short distance, which becomes the distance between the rotating plate, which is lowered due to rotation, and the rising diaphragm, greatly increasing the flow rate. In contrast, in conventional devices, when the solenoid valve is activated, the diaphragm inside the solenoid valve rises, and the water flow can only pass through a small distance in diameter. If a larger solenoid valve is needed to increase the flow rate, the practicality of the device is reduced. In this device, the rising diaphragm drives the rotating plate to rotate, thereby expanding the water flow diameter without changing the size of the solenoid valve, thus improving the practicality of the device.

[0014] (2) During use, if the water pressure is high, the high-speed impact force will impact the lower surface of the diaphragm. The elastic pressure membrane installed on the upper surface of the diaphragm is fixed with a pressure ring. During the impact, the lower surface of the elastic pressure membrane and the lower surface of the pressure ring generate a relative force, squeezing the first protrusion under the pressure ring into the compressed air bag. The compressed air bag contains an acid solution, which reacts with the sodium bicarbonate powder stored in the cavity, and quickly releases a large amount of gas. It can automatically expand to enhance the seal and improve the practicality of the device. Attached Figure Description

[0024] like Figure 1-4The diagram illustrates a high-flow-rate inlet solenoid valve, comprising a main body 1. The main body 1 includes a solenoid valve tube 101. A connecting shell 103 is fixedly connected to the upper surface of the solenoid valve tube 101. An energizing mechanism 2 is installed on the inner wall of the connecting shell 103. The energizing mechanism 2 includes a coil module 201. The upper surface of the coil module 201 is fixedly connected to the inner wall of the connecting shell 103. A spring 204 is fixedly connected to the lower surface of the coil module 201. A first magnetic block 202 is fixedly connected to the end of the spring 204. A connecting... A base 205 is connected to a lower surface of which an auxiliary mechanism 3 is mounted. A sealing mechanism 6 is mounted on the lower surface of the auxiliary mechanism 3. The sealing mechanism 6 includes a diaphragm 601 mounted on the lower surface of the auxiliary mechanism 3. A rotating mechanism 5 is mounted on the inner wall of the solenoid valve tube 101. The rotating mechanism 5 includes a rotating plate 501. A rotating shaft 502 is fixedly connected inside the rotating plate 501. The surface of the rotating shaft 502 is movably connected to the inner wall of the solenoid valve tube 101. A pull rod 505 is movably connected to the upper surface of the rotating plate 501. The end is movably connected to the lower surface of the diaphragm 601. A first magnet 503 is fixedly connected inside the rotating plate 501, and a second magnet 504 is fixedly connected to the inner wall of the solenoid valve tube 101. When the coil module 201 is energized, the current between the first electromagnet 503 and the second electromagnet 504 is broken, attracting the first magnetic block 202 and the second magnetic block 203 upward, causing the connecting seat 205 to move upward. The elastic pressure diaphragm 301 fixed to the lower surface of the connecting seat 205 can then pull the elastic diaphragm 601 upward, causing the diaphragm... The lower surface of 601 is no longer in contact with the upper surfaces of the connecting plate 404 and the rotating plate 501, allowing water to flow through. At the same time, the pull rod 505, which is movably connected to the lower surface of the diaphragm 601, is pulled upward. One end of the rotating plate 501 is subjected to an upward force, causing the rotating plate 501 to rotate counterclockwise around the rotating shaft 502. This changes the water flow diameter inside the solenoid valve pipe 101 from the original small distance the diaphragm 601 rises to the distance between the rotating plate 501, which has decreased in height due to rotation, and the rising diaphragm 601, greatly increasing the flow rate.

[0025] A second magnet 203 is fixedly connected to the upper surface of the connecting seat 205. The second magnet 203 is located to the right of the first magnet 202. The auxiliary mechanism 3 includes an elastic pressure diaphragm 301. The upper surface of the elastic pressure diaphragm 301 is fixedly connected to the lower surface of the connecting seat 205. A pressure ring 302 is fixedly connected to the surface of the elastic pressure diaphragm 301. A cavity 303 is opened inside the elastic pressure diaphragm 301. A compressed air bag 304 is fixedly connected to the inner wall of the cavity 303. A first protrusion 305 is fixedly connected to the upper surface of the compressed air bag 304. A protrusion 305 is located below the pressure ring 302. When encountering high water pressure, the high-speed impact will strike the lower surface of the diaphragm 601. The pressure ring 302 is fixed to the elastic pressure diaphragm 301 mounted on the upper surface of the diaphragm 601. During the impact, the lower surface of the elastic pressure diaphragm 301 and the lower surface of the pressure ring 302 generate a relative force, squeezing the first protrusion 305 below the pressure ring 302 and pushing it into the compressed air bag 304. The compressed air bag 304 contains an acid solution, which interacts with the sodium bicarbonate powder stored inside the cavity 303. The device undergoes a final reaction, rapidly releasing a large amount of gas. It automatically expands to enhance sealing, improving the device's practicality. A flange 102 is fixedly connected to the surface of the solenoid valve tube 101. A first groove 104 is formed on the surface of the solenoid valve tube 101. A fixing mechanism 4 is installed on the surface of the first groove 104. The fixing mechanism 4 includes a sealing ring 402, the surface of which is in contact with the surface of the first groove 104. A pressure block 401 is fixedly connected to the surface of the sealing ring 402, and bolts 403 are installed on the surface of the pressure block 401. The end of the plug 403 extends through the pressure block 401 into the interior of the solenoid valve tube 101. A second groove 506 is provided on the upper surface of the rotating plate 501. A second protrusion 602 is fixedly connected to the lower surface of the diaphragm 601. The second protrusion 602 is located inside the second groove 506. A connecting plate 404 is fixedly connected to the inner wall of the solenoid valve tube 101. A third protrusion 603 is fixedly connected to the lower surface of the diaphragm 601. The third protrusion 603 is located inside the connecting plate 404. The connecting plate 404 is located on the right side of the rotating plate 501.

[0026] Working principle: When the coil module 201 is energized, the current between the first magnet 503 and the second magnet 504 is broken, attracting the first magnetic block 202 and the second magnetic block 203 upwards, causing the connecting seat 205 to move upwards. The elastic pressure diaphragm 301, fixed to the lower surface of the connecting seat 205, pulls the elastic diaphragm 601 upwards, so that the lower surface of the diaphragm 601 is no longer in contact with the upper surfaces of the connecting plate 404 and the rotating plate 501, allowing water to flow through. Simultaneously, the pull rod 505, movably connected to the lower surface of the diaphragm 601, is pulled upwards, and one end of the rotating plate 501 receives an upward force, causing the rotating plate 501 to rotate counterclockwise around the rotating shaft 502. This causes the water flow diameter inside the solenoid valve tube 101 to change from its original diameter. The short distance the diaphragm 601 rises becomes the distance between the rotating plate 501, which is lowered due to rotation, and the rising diaphragm 601, greatly increasing the flow rate. Once the water pressure is high, the high-speed impact force will impact the lower surface of the diaphragm 601. The elastic pressure diaphragm 301 installed on the upper surface of the diaphragm 601 has a pressure ring 302 fixed on it. During the impact, the lower surface of the elastic pressure diaphragm 301 and the lower surface of the pressure ring 302 generate a relative force, squeezing the first protrusion 305 below the pressure ring 302 into the compressed air bag 304. The compressed air bag 304 contains an acid solution, which reacts with the sodium bicarbonate powder stored in the cavity 303, rapidly releasing a large amount of gas. This allows for automatic expansion to enhance the seal and improve the practicality of the device.
