Description

Technical Field

[0001] This utility model relates to the field of solenoid valves, specifically a low-power solenoid valve. Background Technology

[0002] A solenoid valve is an automated basic component that uses electromagnetic principles to control the flow of fluids (liquid or gas). It belongs to the category of actuators and mainly uses the switching of an electromagnet to generate magnetic force, which drives the valve core to move, thereby achieving precise control of the flow direction, flow rate, or pressure of fluids in pipelines.

[0003] In existing technologies, solenoid valves are typically composed of components such as a valve body, valve core, return spring, solenoid coil, and electromagnet. Solenoid valves are applicable to various fields and offer high safety during use. When in operation, solenoid valves rely on energizing the solenoid coil to move the valve core, thereby opening the valve. However, the valve core within the solenoid valve body needs to be energized for extended periods when in the open state. This not only increases the temperature of the solenoid valve during use but also increases its power consumption, thereby increasing the cost of long-term use and the possibility of damage due to prolonged exposure to high temperatures. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the valve core inside the solenoid valve body needs to be energized for a long time when it is in the open state. This not only increases the temperature of the solenoid valve during use, but also increases the power consumption of the solenoid valve, thereby increasing the cost of the solenoid valve during long-term use, and increasing the possibility of damage due to prolonged high temperature. This utility model proposes a low-power solenoid valve.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a low-power solenoid valve, including a solenoid valve body, a connecting rod is provided in the inner cavity of the solenoid valve body, a housing is fixedly connected to the top of the solenoid valve body, and an energy-saving mechanism is provided in the inner cavity of the housing;

[0006] The energy-saving mechanism includes a miniature cylinder, one side of which is fixedly connected to the inner cavity of the housing. A slider is fixedly connected to the output end of the miniature cylinder. One side of the slider is slidably connected to the inner cavity of the housing. A connecting plate is rotatably connected to one side of the slider. A rotating rod is rotatably connected to the inner cavity of the connecting plate. A rotating plate is rotatably connected to the surface of the rotating rod. An mounting rod is fixedly connected to the inner cavity of the rotating plate. One end of the mounting rod is rotatably connected to the inner cavity of the housing. An incomplete gear is fixedly connected to the surface of the mounting rod. A rack is slidably connected to the inner cavity of the housing. The teeth of the incomplete gear mesh with the teeth of the rack. A limiting component is provided on one side of the housing.

[0007] Preferably, the limiting component includes a movable block, one side of which is fixedly connected to one side of the rack, a fixed rod is slidably connected to the inner cavity of the movable block, a locking block is fixedly connected to one end of the fixed rod, a pushing spring is fixedly connected between the locking block and the fixed rod, a locking groove is formed on the surface of the connecting rod, and a fixing ring block is fixedly connected to one end of the fixed rod.

[0008] Preferably, a fixing plate is fixedly connected to the inner cavity of the housing, a sliding groove is provided on one side of the micro cylinder, the surface of the fixing plate is slidably connected to the inner cavity of the sliding groove, and a PLC controller is fixedly connected to the inner cavity of the housing.

[0009] Preferably, a limiting plate is fixedly connected to the inner cavity of the housing, and a slide rod is fixedly connected to the bottom of the rack, with the bottom of the slide rod slidably connected to the inner cavity of the housing.

[0010] Preferably, a limiting ring block is fixedly connected to the surface of the mounting rod, one side of the limiting ring block is rotatably connected to the inner cavity of the housing, and an FKM gasket and a labyrinth sealing block are fixedly connected to the top of the solenoid valve body.

[0011] Preferably, a limiting plate is fixedly connected to the inner cavity of the housing, and the surface of the limiting plate is slidably connected to the inner cavity of the moving block.

[0012] Preferably, a reinforcing rod is fixedly connected to one side of the slider, and the surface of the reinforcing rod is rotatably connected to the inner cavity of the connecting plate.

[0013] The advantages of this utility model are:

[0014] This invention utilizes a miniature cylinder to pull a slider. As the slider moves, it drives an incomplete gear to rotate around the center of the mounting rod via a connecting plate and a rotating plate. This rotation pushes a moving block and a locking block, allowing the locking block to smoothly insert into the slot. When the valve core inside the solenoid valve body is in the open state, the connection between the locking block and the slot restricts the connecting rod, ensuring the valve core remains in a restricted and open state for an extended period. This reduces power consumption during operation, thus lowering the overall power consumption of the solenoid valve body. It also solves the problem of the valve core needing to be continuously energized when open, which increases the valve's temperature and power consumption, leading to higher long-term costs and increased risk of damage due to prolonged high temperatures.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a low-power solenoid valve. (Refer to...) Figure 1 and Figure 3A low-power solenoid valve includes a solenoid valve body 1, a connecting rod 2 is provided in the inner cavity of the solenoid valve body 1, a housing 3 is fixedly connected to the top of the solenoid valve body 1, and an energy-saving mechanism 4 is provided in the inner cavity of the housing 3.

[0025] The energy-saving mechanism 4 includes a miniature cylinder 401. One side of the miniature cylinder 401 is fixedly connected to the inner cavity of the housing 3. A slider 402 is fixedly connected to the output end of the miniature cylinder 401. One side of the slider 402 is slidably connected to the inner cavity of the housing 3. A connecting plate 404 is rotatably connected to one side of the slider 402. A rotating rod 405 is rotatably connected to the inner cavity of the connecting plate 404. A rotating plate 406 is rotatably connected to the surface of the rotating rod 405. An installation rod 403 is fixedly connected to the inner cavity of the rotating plate 406. One end of the installation rod 403 is rotatably connected to the inner cavity of the housing 3. An incomplete gear 407 is fixedly connected to the surface of the installation rod 403. A rack 408 is slidably connected to the inner cavity of the housing 3. The teeth of the incomplete gear 407 mesh with the teeth of the rack 408. A limiting component 409 is provided on one side of the housing 3.

[0026] The connecting rod 2 can be connected to the valve core inside the solenoid valve body 1, and can be connected by a thread to increase the stability of the connection between the two. The housing 3 can be used to install and fix the miniature cylinder 401. The miniature cylinder 401 can not only connect to the slider 402, but also drive the slider 402 to move during operation. The slider 402 can be connected to the rotating rod 405 through the connecting plate 404. When the connecting plate 404 rotates, it can drive the rotating plate 406 to rotate together through the rotating rod 405. The rotating plate 406 can be connected to the incomplete gear 407 through the mounting rod 403. This allows the incomplete gear 407 to rotate through the mounting rod 403 when the rotating plate 406 rotates. Furthermore, the meshing between the incomplete gear 407 and the rack 408 allows the rack 408 to slide along the inner wall of the housing 3 when the incomplete gear 407 rotates.

[0027] Reference Figure 3 and Figure 4The limiting component 409 includes a movable block 4091, one side of which is fixedly connected to one side of a rack 408. A fixed rod 4092 is slidably connected to the inner cavity of the movable block 4091. A locking block 4094 is fixedly connected to one end of the fixed rod 4092. A pushing spring 4093 is fixedly connected between the locking block 4094 and the fixed rod 4092. A slot 4095 is provided on the surface of the connecting rod 2. A fixed ring block 4096 is fixedly connected to one end of the fixed rod 4092. The rack 408 can be connected to the pushing spring 4093 through the movable block 4091, and the pushing spring 4093 can be smoothly connected to the locking block 4094. When the rack 408 moves, it can smoothly push the rack 408 through the connection between itself and the movable block 4091. The spring 4093 and the locking block 4094 move together. When the locking block 4094 is inserted into the slot 4095, it can restrict the connecting rod 2. This allows the locking block 4094 to smoothly restrict the connecting rod 2 and the valve core through the slot 4095 after the connecting rod 2 moves upward through the valve core inside the solenoid valve body 1. The fixed rod 4092 not only supports the locking block 4094 through its connection with the moving block 4091, but also allows the fixed ring block 4096 to push the fixed ring block 4096 and the fixed rod 4092 smoothly when the moving block 4091 moves in the opposite direction, thereby enabling the locking block 4094 to move out of the slot 4095.

[0028] Reference Figure 4 and Figure 5 A fixing plate 13 is fixedly connected to the inner cavity of the housing 3. A sliding groove 12 is provided on one side of the micro cylinder 401. The surface of the fixing plate 13 is slidably connected to the inner cavity of the sliding groove 12. A PLC controller 5 is fixedly connected to the inner cavity of the housing 3. The setting of the sliding groove 12 and the fixing plate 13 can effectively limit the sliding of the slider 402, so that the slider 402 can slide more stably when it is pushed by the operation of the micro cylinder 401. The PLC controller 5 is electrically connected to the solenoid valve body 1 and the micro cylinder 401. The setting of the PLC controller 5 allows the solenoid valve body 1 to drive the micro cylinder 401 to operate while in use and operation. The PLC controller 5 controls the solenoid valve body 1 to be energized to drive the valve core to open. After the valve core inside the solenoid valve body 1 is in place, the micro cylinder 401 is activated to operate. Then the power supply of the solenoid valve body 1 is cut off to achieve low power consumption maintenance. The solenoid valve body 1 and the PLC controller 5 are existing technologies in this field, so they will not be described in detail here.

[0029] Reference Figure 3 and Figure 4A limiting plate 8 is fixedly connected to the inner cavity of the housing 3, and a sliding rod 7 is fixedly connected to the bottom of the rack 408. The bottom of the sliding rod 7 is slidably connected to the inner cavity of the housing 3. The limiting plate 8 can limit the movement of the sliding rod 7, so that when the rack 408 slides inside the housing 3, it can be effectively restricted by the sliding rod 7 and the limiting plate 8, thereby improving the stability of the rack 408 when sliding inside the housing 3.

[0030] Reference Figure 5 A limiting ring 9 is fixedly connected to the surface of the mounting rod 403. One side of the limiting ring 9 is rotatably connected to the inner cavity of the housing 3. An FKM gasket 10 and a labyrinth seal block 11 are fixedly connected to the top of the solenoid valve body 1. The FKM gasket 10 and the labyrinth seal block 11 can effectively seal the gap between the connecting rod 2 and the solenoid valve body 1, so that the connecting rod 2 has high sealing performance when in use, and it is not easy for the solenoid valve body 1 to fail to work smoothly due to a large gap between itself and the solenoid valve body 1.

[0031] Reference Figure 4 A limiting plate 6 is fixedly connected to the inner cavity of the housing 3. The surface of the limiting plate 6 is slidably connected to the inner cavity of the moving block 4091. The limiting plate 6 can effectively restrict the movement of the moving block 4091, thereby further improving the stability and smoothness of the moving block 4091 and the rack 408 during the movement process.

[0032] Reference Figure 4 and Figure 5 A reinforcing rod 14 is fixedly connected to one side of the slider 402. The surface of the reinforcing rod 14 is rotatably connected to the inner cavity of the connecting plate 404. The reinforcing rod 14 can strengthen the connection between the connecting plate 404 and the slider 402, thereby making the use of the connecting plate 404 more stable when the slider 402 moves and drives the connecting plate 404 to move and rotate.

[0033] Working Principle: When using this device, the solenoid valve body 1 can be installed normally, and the connecting rod 2 can be connected to the valve core inside the solenoid valve body 1. When the solenoid valve body 1 is activated and the valve core is opened, the solenoid valve body 1 can drive the micro cylinder 401 to operate through the settings of the PLC controller 5. The connecting rod 2 will move upward due to the opening of the valve core. At this time, the operation of the micro cylinder 401 can pull the slider 402, causing the slider 402 to move to one side. Simultaneously, the connecting plate 404 pulls the rotating rod 405 and the rotating plate 406, causing the rotating plate 406 to drive the mounting rod 403 to rotate, thereby rotating the incomplete gear 407. The incomplete gear 407 can then rotate through itself and the rack 4... The meshing between 08 drives the rack 408 to move. During the movement, the rack 408 can push the push spring 4093 and the locking block 4094 through the moving block 4091. At this time, the locking block 4094 will move closer to the connecting rod 2 and contact the connecting rod 2. Since the moving block 4091 and the fixed rod 4092 are slidably connected, the movement of the moving block 4091 will push the push spring 4093. When the connecting rod 2 moves up a certain distance, the locking block 4094 can be smoothly inserted into the slot 4095 through the elasticity released by the push spring 4093, thereby restricting the connecting rod 2. At this time, the solenoid valve body 1 can cancel the power when keeping the valve core open, thereby saving power consumption.

[0034] When it is necessary to close the valve core, simply restart the micro cylinder 401 to push the slider 402. At this time, the rack 408 can move in the opposite direction, which in turn drives the moving block 4091 to move synchronously. After the moving block 4091 moves in the opposite direction to a certain distance, it will push the fixed ring block 4096, causing the fixed ring block 4096 to drive the locking block 4094 to move away from the connecting rod 2. When the locking block 4094 is completely removed from the slot 4095, the connecting rod 2 and the valve core inside the solenoid valve body 1 will be reset by the return spring inside the solenoid valve body 1, thus closing the valve core.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
