Technical Field
[0001] The utility model relates to the technical field related to solenoid valves, and in particular to a leakage-proof solenoid valve. Background Art
[0002] A solenoid valve is a device that uses electromagnetic force to control the flow of fluid and is widely used in automation systems. It is mainly composed of a solenoid coil, a valve body, and a valve seat. When current passes through the solenoid coil, the magnetic field generated drives the valve core or valve plate to move, thereby opening or closing the fluid channel to achieve precise control of gas, liquid, or steam. Solenoid valves can be divided into two types: normally open and normally closed. They are suitable for various working conditions, such as water treatment, air conditioning, chemical industry, mechanical equipment, etc. Due to their simple structure, fast response, and high reliability, solenoid valves play an important role in modern industrial automation and intelligent control. With the continuous development of science and technology, the requirements for solenoid valves are also getting higher and higher. Therefore, there is a special need for a leakage-proof solenoid valve.
[0003] However, although the existing anti-leakage solenoid valve completes the sealing of the solenoid valve body through the combination of simple parts, during the sealing process, when vibration occurs, the engaged compression spring and torsion spring will drive the shift limit plate to move, thereby affecting the sealing effect of the device.

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.
[0025] See also Figure 1-6, the utility model provides a technical solution: an anti-leakage solenoid valve, comprising a solenoid valve body 1 and a locking mechanism 2, wherein the locking mechanism 2 is provided on one side of the surface of the solenoid valve body 1;
[0026] The locking mechanism 2 includes a locking block 201, a water outlet 202, a first slide 203, a limiting groove 204, a second slide 205, a first slide bar 206, a first spring 207, a torsion spring 208, a second slide bar 209, a second spring 210, a fixing plate 211, a slider 212, a limiting block 213, a baffle 214, a block 215 and a third spring 216. The two sides of the solenoid valve body 1 are fixedly connected with the locking block 201, a water outlet 202 is provided on one side of the locking block 201, a first slide 203 is provided inside the locking block 201, a limiting groove 204 is provided on the other side of the first slide 203, a second slide 205 is provided on the inner wall of the first slide 203, and the first slide bar 2 is embedded in the interior of the first slide 203. 06, one side of the first slide groove 203 is connected to a first spring 207, one end of the limiting groove 204 is installed with a torsion spring 208, the interior of the second slide groove 205 is embedded with a second slide rod 209, one end of the second slide groove 205 is connected to a second spring 210, the surface of the first slide rod 206 is fixedly connected to a fixing plate 211, the surface of the first slide rod 206 is embedded with a slider 212, the other side of the first slide rod 206 is fixedly connected to a limiting block 213, the surface of the torsion spring 208 is connected to a baffle 214, the other side of the second slide rod 209 is connected to a card block 215, and one side of the slider 212 is connected to a third spring 216. Through the locking block 201, the water outlet 202, the first slide groove 203, the limiting groove 204, the second slide groove 205, the first The arrangement of a slide bar 206, a first spring 207, a torsion spring 208, a second slide bar 209, a second spring 210, a fixing plate 211, a slider 212, a limit block 213, a baffle 214, a clamping block 215 and a third spring 216. When in use, first press the first slide bar 206, the first slide bar 206 drives the limit block 213 and the parts thereon to move, and at the same time the first spring 207 is compressed and deformed, and then the movement of the limit block 213 will cause the baffle 214 to rotate, and the baffle 214 rotates inside the limit groove 204 through the torsion spring 208. When one side of the limit block 213 presses the clamping block 215, the clamping block 215 will press the second slide bar 209, and the second slide bar 209 presses the second spring 210 to compress and deform. When the limit block 213 is pressed, the clamping block 215 will press the second slide bar 209. The second slide bar 209 presses the second spring 210 to compress and deform. When the block 213 completely leaves the block 215, the limit block 213 isolates the water outlet 202, and the block 215 engages one side of the limit block 213, thereby completing the closure. At the same time, when pulling out, the first slide bar 206 is continuously pressed, and the first slide bar 206 drives the slider 212 to move, and the slider 212 drives the third spring 216 to compress and deform. When the slider 212 completely passes the block 215, the limit block 213 will be separated from the restriction of the block 215 through the slider 212, thereby causing the slider 212 and the limit block 213 to slide from the limit groove 204 to the first slide groove 203. At the same time, the sliding of the limit block 213 causes the baffle 214 to resume rotation, thereby closing the limit groove 204 and providing support for the limit block 213.
[0027] Furthermore, one side of the limit groove 204 passes through the water outlet 202, and the baffle 214 matches the size of the limit groove 204. Through the setting of the limit groove 204, the limit groove 204 provides a clear range of motion for the limit block 213 to prevent it from excessive sliding and causing system failure. By limiting the movement of the limit block 213, it is ensured that it operates within the design range, thereby maintaining the stability of the mechanism. At the same time, when the limit block 213 reaches a certain level in the limit groove 204, the other side of the limit block 213 engages with the block 215 to lock the position of the first slide bar 206, ensuring that the solenoid valve is in a closed state. This locking mechanism prevents accidental opening when the valve is closed, thereby improving safety.
[0028] Furthermore, a fixed plate 211 is connected to the other side of the first spring 207, and the first slide bar 206 forms a mutual sliding structure with the first slide groove 203 through the first spring 207. Through the setting of the first spring 207, the first spring 207 provides the first slide bar 206 with the necessary movement resistance, so that it can slide smoothly in the first slide groove 203, thereby realizing rapid control of the water flow. At the same time, the elastic force of the spring helps to maintain the position of the slide bar in the normal operating state, preventing it from being offset due to external forces, thereby ensuring the stability of the system. Finally, after the solenoid valve is closed or the signal is released, the first spring 207 prompts the first slide bar 206 to return to the initial position through its restoring force, realizing automatic return, and ensuring that the system can return to the ready state after each operation.
[0029] Furthermore, two groups of second slide grooves 205 are provided, and the two groups of second slide grooves 205 are symmetrical to each other. Through the setting of the second slide grooves 205, the second slide grooves 205 provide a stable sliding track for the second slide bar 209, ensuring that it can move smoothly during operation, prevent tilting or jamming, and ensure the smooth operation of the system. The second slide grooves 205 and the first slide grooves 203 complement each other, so that the limit block 213 can be engaged on the block 215, and through the symmetrical design, the force applied to the slide bar can be balanced, thereby enhancing the stability of the overall structure.
[0030] Furthermore, the other side of the second spring 210 is connected to a second slide bar 209, and the second slide bar 209 forms a mutual sliding structure with the second slide groove 205 through the second spring 210. Through the setting of the second spring 210, the second spring 210 provides the second slide bar 209 with the necessary restoring force to ensure that it can slide smoothly during operation and can quickly return to the initial position after the control signal is released. At the same time, the cooperation between the second spring 210 and the first slide bar 206 ensures that the blocking block 215 can engage the limit block 213 to the corresponding position, thereby closing the solenoid valve.
[0031] Furthermore, one side of the baffle 214 is in contact with the limit block 213, and one side of the limit block 213 is engaged with the card block 215. Through the setting of the baffle 214 and the card block 215, the baffle 214 contacts the limit block 213, helping to limit the movement range of the first slide bar 206, ensuring that it does not exceed the designed track during normal operation. When the solenoid valve is closed, the combination of the baffle 214 and the limit groove 204 ensures that the slide bar is in a locked state to prevent accidental opening and improve safety. The engagement of the card block 215 with the limit block 213 enhances the stability of the locking mechanism 2 and ensures a tight connection between the various components during operation.
[0032] Furthermore, the other side of the third spring 216 is connected to a fixed plate 211, and the slider 212 forms a mutual sliding structure with the first slide bar 206 through the third spring 216. Through the setting of the slider 212, the slider 212 realizes the control of the solenoid valve by sliding with the first slide bar 206 to ensure the opening and closing of the water flow. It effectively transmits the force applied by the spring during the sliding process. After the solenoid valve is closed or the signal is released, the slider 212 helps the first slide bar 206 return to its initial position through the action of the third spring 216, ensuring the recovery state after each operation.
[0033] Furthermore, the first spring 207 and the third spring 216 are both arranged on the outside of the first slide bar 206, and the limit block 213 is tightly embedded in the inside of the limit groove 204. Through the setting of the limit block 213, the design of the limit block 213 provides a clear range of motion for the first slide bar 206, preventing the slide bar from sliding excessively, thereby ensuring stable operation of the system. When the solenoid valve is closed, the limit block 213 contacts the water outlet 202, and then closes the solenoid valve, thereby improving the safety of the system and maintaining the reliability of the entire mechanism.
[0034] Working principle: First, press the first slide bar 206, the first slide bar 206 drives the limit block 213 and the parts thereon to move, and at the same time the first spring 207 is compressed and deformed, and then the movement of the limit block 213 will cause the baffle 214 to rotate, and the baffle 214 rotates inside the limit groove 204 through the torsion spring 208. When one side of the limit block 213 presses the block 215, the block 215 will press the second slide bar 209, and the second slide bar 209 presses the second spring 210 to compress and deform. When the limit block 213 completely leaves the block 215, the limit block 213 will isolate the water outlet 202, and the block 21 5. One side of the limit block 213 is engaged to complete the closure. At the same time, when withdrawing, the first slide bar 206 is continuously pressed. The first slide bar 206 drives the slider 212 to move, and the slider 212 drives the third spring 216 to compress and deform. When the slider 212 completely passes the block 215, the limit block 213 is released from the restriction of the block 215 through the slider 212, thereby allowing the slider 212 and the limit block 213 to slide from the limit slot 204 to the first slide slot 203. At the same time, the sliding of the limit block 213 causes the baffle 214 to resume rotation, thereby closing the limit slot 204 and providing support for the limit block 213.
[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
