Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valves. More specifically, the utility model relates to a structure of a micro solenoid valve that can be quickly assembled. Background Technique

[0002] A micro solenoid valve is a miniaturized and simple-structured electromagnetic control device, which is mainly used for controlling and regulating fluid media. When the electromagnetic coil is energized, a magnetic field will be generated. This magnetic field will attract the valve core with the opposite polarity, causing the valve core to disengage from the valve seat, thereby opening the valve and allowing the medium to flow. Conversely, when the electromagnetic coil is de-energized, the magnetic field disappears, and the valve core returns to the valve seat under the action of forces such as springs, closing the valve and preventing the medium from flowing. By controlling the on / off of the electromagnetic coil, precise control of the medium flow can be achieved.

[0003] At present, in the processing and production process of traditional micro solenoid valves, their assembly process is relatively complex, often involving the manual assembly and debugging of multiple fine components. This not only requires operators to have a high level of professional skills but also may lead to fluctuations in assembly quality and an increase in the defective rate. Moreover, when a failure occurs during the use of the solenoid valve, its maintenance and replacement are more cumbersome. Usually, professional technicians need to use specific tools to carry out effective repairs or replacements. This high skill threshold and tool dependence not only increase the maintenance cost but also may affect the normal operation of the overall production or system due to delays in repair time. Therefore, it is necessary to improve and optimize it. Content of the Utility Model

Specific implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1 to 7 shown, the present utility model provides a micro solenoid valve structure that can be quickly assembled, including a valve tube 1. Thread grooves 2 are provided on the inner walls of the left and right sides of the valve tube 1. A mounting seat 3 is fixedly installed on the top of the valve tube 1, and a controller housing 4 is detachably installed inside the mounting seat 3;

[0026] Positioning blocks 9 are fixedly installed on the left and right sides of the bottom of the controller housing 4. Assembly holes 10 are provided inside the positioning blocks 9. Movable grooves 24 are provided on the left and right sides inside the mounting seat 3. A fixing rod 12 is movably installed inside the movable groove 24. The fixing rod 12 and the inner wall of the movable groove 24 are elastically connected by a second spring 13. The bottom of the fixing rod 12 passes through the assembly hole 10 and fixes the positioning block 9;

[0027] On the left and right sides inside the mounting base 3, limiting grooves 18 are provided. A push rod 15 is movably installed inside the limiting grooves 18. One end of the push rod 15 is fixedly installed with a transmission block 16. On the left and right sides of the mounting base 3, a first bolt 19 is rotatably installed, and the first bolt 19 is threadedly sleeved with the push rod 15.

[0028] When the device needs to be assembled, the staff picks up the controller housing 4 and aligns the two positioning blocks 9 at its bottom with the assembly grooves 11, and then presses it down. At this time, the positioning blocks 9 and the assembly grooves 11 are engaged with each other. Then the staff rotates the controller housing 4 to make the positioning blocks 9 slide inside the assembly grooves 11. After it cannot slide, the staff rotates the first bolt 19. The rotation of the first bolt 19 drives the displacement of the push rod 15 threadedly sleeved with it. At this time, the push rod 15 is restricted by the limiting block 17 and the limiting groove 18, so that the push rod 15 displaces inward. Further, the transmission block 16 at one end of the push rod 15 abuts against the transmission groove 14, so that the transmission block 16 pushes the fixing rod 12 downward along the movable groove 24 through the transmission groove 14. At this time, the second spring 13 is stretched, and the bottom of the fixing rod 12 penetrates through the assembly hole 10 to fix the positioning block 9, completing the installation of the controller housing 4. When disassembly is required, the staff rotates the first bolt 19 in the reverse direction to reset the push rod 15. At this time, the fixing rod 12 that loses the abutment of the transmission block 16 resets upward through the elastic potential energy of the second spring 13. At this time, the staff rotates the controller housing 4 to disassemble the controller housing 4. When the device is working, the staff fixes the valve pipe 1 through the thread groove 2 and the pipeline. At this time, the staff energizes the coil 5 to generate a magnetic field, and this magnetic field will attract the plug 7 with the opposite polarity to displace, so as to allow the fluid medium to flow through the valve pipe 1, realizing the function of the solenoid valve.

[0029] Through the setting of the assembly grooves 11, the controller housing 4 can be clamped inside the mounting base 3 through the positioning blocks 9, so that the controller housing 4 is initially spliced, so that when the staff operates, the controller housing 4 is not easily detached from the mounting base 3, improving the installation efficiency. By rotating the first bolt 19, the transmission block 16 pushes the fixing rod 12 downward along the movable groove 24 through the transmission groove 14, and further the controller housing 4 is installed. Compared with the traditional device, this device can complete the initial fixation and firm fixation of the controller housing 4 by clamping and rotating the first bolt 19, making the disassembly and assembly of the controller housing 4 convenient, the assembly rapid, and improving the work efficiency and maintenance efficiency.

[0030] Wherein, fixed shells 20 are fixedly installed on the left and right sides of the valve pipe 1. A moving block 21 is movably installed on the top of the fixed shell 20. A second bolt 22 is rotatably installed on the top of the fixed shell 20. The second bolt 22 is threadedly sleeved with the moving block 21. A clamping block 23 is fixedly installed at the bottom of the moving block 21.

[0031] The staff fixes the valve pipe 1 through the thread groove 2 and the pipeline. After the fixing is completed, the staff rotates the second bolt 22. The rotation of the second bolt 22 drives the moving block 21 sleeved with its thread to move downward along the fixed shell 20. Further, the clamping block 23 abuts against the outer wall of the pipeline. At this time, the clamping block 23 cooperates with the fixed shell 20 to fix the outer wall of the pipeline, preventing the pipeline from loosening and leaking liquid.

[0032] By rotating the second bolt 22, the moving block 21 moves downward along the fixed shell 20. Further, the clamping block 23 abuts against the outer wall of the pipeline. At this time, the clamping block 23 cooperates with the fixed shell 20 to fix the outer wall of the pipeline. Compared with the traditional device, this device can reinforce the outer wall of the pipeline after the pipeline connection is completed, prevent the pipeline from loosening, and further reduce the occurrence of pipeline liquid leakage, improving the product quality.

[0033] Among them, a plug 7 is movably installed inside the controller housing 4. The bottom of the plug 7 penetrates into the inside of the valve pipe 1. A fixed iron core 6 is fixedly installed inside the controller housing 4. The fixed iron core 6 and the plug 7 are elastically connected by a first spring 8. A coil 5 is arranged inside the controller housing 4.

[0034] The staff energizes the coil 5 to generate a magnetic field, and this magnetic field will attract the plug 7 with the opposite polarity to displace, thereby allowing the fluid medium to flow through the valve pipe 1, realizing the function of the solenoid valve.

[0035] Among them, an assembly groove 11 is opened inside the mounting seat 3, and a positioning block 9 is clamped inside the assembly groove 11.

[0036] The assembly groove 11 clamps the positioning block 9, enabling the preliminary splicing of the controller housing 4, so that when the staff operates, the controller housing 4 is not easily detached from the mounting seat 3.

[0037] Among them, a transmission groove 14 is opened on the outer wall of the fixed rod 12, and the inclined surface of the transmission groove 14 is parallel to the inclined surface of the transmission block 16. The transmission block 16 abuts against the transmission groove 14.

[0038] One end of the push rod 15, the transmission block 16, abuts against the transmission groove 14, enabling the transmission block 16 to push the fixed rod 12 downward along the movable groove 24 through the transmission groove 14 to realize transmission.

[0039] Among them, a limiting block 17 is opened on the outer wall of the push rod 15, and the limiting block 17 is movably installed inside the limiting groove 18 to limit the moving path of the push rod 15.

[0040] The push rod 15 is restricted by the limiting block 17 and the limiting groove 18, enabling the push rod 15 to displace inward and restricting the moving direction of the push rod 15.

[0041] The working principle and usage process of the present utility model:

[0042] When the device needs to be assembled, the staff picks up the controller housing 4 and aligns the two groups of positioning blocks 9 at its bottom with the assembly slots 11, and then presses them down. At this time, the positioning blocks 9 and the assembly slots 11 are engaged with each other. Then the staff rotates the controller housing 4 to make the positioning blocks 9 slide inside the assembly slots 11. After it can no longer slide, the staff rotates the first bolt 19. The rotation of the first bolt 19 drives the displacement of the push rod 15 sleeved with its thread. At this time, the push rod 15 is restricted by the limit block 17 and the limit slot 18, so that the push rod 15 displaces inward. Further, the transmission block 16 at one end of the push rod 15 abuts against the transmission slot 14, and the transmission block 16 pushes the fixing rod 12 downward along the movable slot 24 through the transmission slot 14. At this time, the second spring 13 is stretched, and the bottom of the fixing rod 12 penetrates through the assembly hole 10 to fix the positioning block 9, completing the installation of the controller housing 4. When disassembly is required, the staff rotates the first bolt 19 in the reverse direction to reset the push rod 15. At this time, the fixing rod 12 that loses the abutment of the transmission block 16 resets upward through the elastic potential energy of the second spring 13. At this time, the staff rotates the controller housing 4 to disassemble the controller housing 4. When the device is working, the staff fixes the valve pipe 1 to the pipeline through the thread groove 2. At this time, the staff energizes the coil 5 to generate a magnetic field, and this magnetic field will attract the plug 7 with the opposite polarity to displace, so as to allow the fluid medium to flow through the valve pipe 1, realizing the function of the solenoid valve.

[0043] The staff fixes the valve pipe 1 to the pipeline through the thread groove 2. After the fixing is completed, the staff rotates the second bolt 22. The rotation of the second bolt 22 drives the moving block 21 sleeved with its thread to move downward along the fixed housing 20. Further, the clamping block 23 abuts against the outer wall of the pipeline. At this time, the clamping block 23 cooperates with the fixed housing 20 to fix the outer wall of the pipeline to prevent the pipeline from loosening and leaking liquid.
