Description

Technical Field

[0001] This application relates to the field of solenoid valves, and more particularly to an anti-clogging solenoid valve spool assembly. Background Technology

[0002] A solenoid valve is an automated actuator that uses electromagnetic force to control the on / off state or flow direction of fluid. It is a fundamental device in industrial control systems for regulating parameters such as the direction and flow rate of the medium. It is widely used in hydraulic, pneumatic systems, and industrial automation. Its core structure includes components such as an electromagnetic coil, valve core, and valve body. Fluid control is achieved by generating a magnetic field through energization, which drives the valve core to move. A valve core is often installed inside a solenoid valve to regulate the flow direction of water. The valve core is the core component inside the solenoid valve used to control the on / off state or change the flow direction of fluid. It is usually made of metal or high-performance plastic and is located inside the valve body. In conventional solenoid valve assembly installation, the valve stem is installed inside the solenoid valve using a threaded rod. Several rubber retaining rings are installed on the surface of the valve stem. These retaining rings improve the sealing between the valve stem and the inside of the solenoid valve and also shield the inside of the solenoid valve. The inner wall of the valve stem has a water flow channel and a connection port, facilitating water flow. The valve stem moves using the magnetic field generated by the solenoid valve, controlling the position of the retaining rings to shield the water flow channel, thus facilitating water flow control.

[0003] Regarding the aforementioned technologies, the inventors believe that when conventional solenoid valve core assemblies are in use, the fluid in the pipeline may contain impurities such as welding slag, rust, and slag. These impurities are easily deposited on the valve core and sealing surface during the flow process, causing blockage of the solenoid valve core. This requires frequent cleaning by operators and affects the daily use of the solenoid valve.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

Detailed Implementation

[0022] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0023] This application discloses an anti-clogging solenoid valve core assembly, referring to... Figure 1 - Figure 2 The valve assembly includes a valve stem 1. During installation, the valve stem 1 is installed inside the solenoid valve via a threaded rod 2. Several rubber retaining rings 3 are installed on the surface of the valve stem 1. The retaining rings 3 improve the sealing between the valve stem 1 and the solenoid valve and also shield the inside of the solenoid valve. The inner wall of the valve stem 1 has a water flow channel 4 and a connection port 5, which facilitates the flow of water. The valve stem 1 moves with the help of the magnetic field generated by the solenoid valve, controlling the position of the retaining rings 3 to shield the water flow channel 4, thereby facilitating the control of water flow. A first connecting ring 6 and a second connecting ring 7 are installed on the surface of the valve stem 1. One end of the first connecting ring 6 and the second connecting ring 7 is snapped with a mounting bracket 8. The inner wall of the mounting bracket 8 is equipped with a shielding mesh 9. The shielding mesh 9 filters the water entering the retaining rings 3 and pushes impurities to the positions of the first connecting rings 6 and the second connecting rings 7, effectively improving the anti-clogging ability of the valve core assembly and preventing impurities from clogging the position of the retaining rings 3.

[0024] Reference Figure 2 Both the first connecting ring 6 and the second connecting ring 7 have a locking block 10 installed at one end. The surface of the locking block 10 engages with the inner wall of the mounting bracket 8. The mounting bracket 8 is installed at one end of the first connecting ring 6 and the second connecting ring 7 using the locking block 10. Separating the locking block 10 from the mounting bracket 8 facilitates the disassembly of the shielding net 9, making subsequent cleaning work more convenient. The inner wall of the first connecting ring 6 has a sliding groove 11, and a connecting block 12 is slidably connected to the inner wall of the sliding groove 11. One end of the connecting block 12 is connected to the surface of the second connecting ring 7. The sliding groove 11 and the connecting block 12 facilitate the disassembly of the first connecting ring 6 and the second connecting ring 7. The connecting ring 6 and the second connecting ring 7 are adjusted to facilitate the separation of the locking block 10 from the mounting bracket 8, making disassembly of the device more convenient. The maximum movement of the first connecting ring 6 and the second connecting ring 7 is also limited. Two pull springs 13 are installed at one end of the connecting block 12. One end of the pull spring 13 is connected to the inner wall of the slide groove 11. The pull spring 13 pulls the connecting block 12, thereby keeping the locking block 10 at one end of the first connecting ring 6 and the second connecting ring 7 locked to the inner wall of the mounting bracket 8, effectively improving the connection effect between the mounting bracket 8 and the locking block 10.

[0025] Reference Figure 2 - Figure 4Waste boxes 14 are installed on the surfaces of the first connecting ring 6 and the second connecting ring 7. The waste boxes 14 collect the impurities filtered out by the shielding net 9, making it convenient for staff to process the impurities later. The inner wall of the waste box 14 is fitted with a fixing bolt 15. The surface of the fixing bolt 15 is threaded to the inner wall of the first connecting ring 6 and the second connecting ring 7. The two waste boxes 14 are installed on the surface of the first connecting ring 6 and the second connecting ring 7 with the fixing bolt 15. The waste boxes 14 can be opened by separating the fixing bolt 15 from the first connecting ring 6 and the second connecting ring 7, making it convenient to process the impurities in the waste boxes 14. Several rubber auxiliary plates 16 are installed on the inner wall of the first connecting ring 6 and the second connecting ring 7. The inner wall of the auxiliary plates 16 is connected to the surface of the valve stem 1. The auxiliary plates 16 increase the friction between the first connecting ring 6, the second connecting ring 7 and the valve stem 1, thereby ensuring the stability of the device installation and keeping the shielding net 9 and the water flow channel 4 in a straight line.

[0026] The implementation principle of the anti-clogging solenoid valve core assembly in this application embodiment is as follows: A first connecting ring 6 and a second connecting ring 7 are mounted on the surface of the valve stem 1. One end of the first connecting ring 6 and the second connecting ring 7 is engaged with a mounting bracket 8. A baffle net 9 is installed on the inner wall of the mounting bracket 8 to filter the water flowing into the fixed ring 3. The water flow also pushes impurities towards the positions of the first connecting ring 6 and the second connecting ring 7, effectively improving the anti-clogging capability of the valve core assembly and preventing impurities from clogging the fixed ring 3. A locking block 10 is installed at one end of both the first connecting ring 6 and the second connecting ring 7. The surface of the locking block 10 engages with the inner wall of the mounting bracket 8, allowing the mounting bracket 8 to be installed at one end of the first connecting ring 6 and the second connecting ring 7. Separating the locking block 10 from the mounting bracket 8 facilitates the disassembly of the baffle net 9. For easier subsequent cleaning, the inner wall of the first connecting ring 6 is provided with a groove 11, and a connecting block 12 is slidably connected to the inner wall of the groove 11. One end of the connecting block 12 is connected to the surface of the second connecting ring 7, so that the first connecting ring 6 and the second connecting ring 7 can be easily adjusted with the help of the groove 11 and the connecting block 12, and the locking block 10 can be easily separated from the mounting frame 8. This makes it easier to disassemble the device and limits the maximum movement of the first connecting ring 6 and the second connecting ring 7. Two pull springs 13 are installed at one end of the connecting block 12, and one end of the pull spring 13 is connected to the inner wall of the groove 11, so that the pull spring 13 can pull the connecting block 12, thereby keeping the locking block 10 at one end of the first connecting ring 6 and the second connecting ring 7 locked to the inner wall of the mounting frame 8, effectively improving the connection effect between the mounting frame 8 and the locking block 10.

[0027] Waste boxes 14 can also be installed on the surfaces of the first connecting ring 6 and the second connecting ring 7 to collect impurities filtered out by the shielding net 9, thus facilitating subsequent processing of the impurities. A fixing bolt 15 is snapped into the inner wall of the waste box 14, and the surface of the fixing bolt 15 is threadedly connected to the inner walls of the first connecting ring 6 and the second connecting ring 7. This allows the two waste boxes 14 to be installed on the surfaces of the first connecting ring 6 and the second connecting ring 7 using the fixing bolt 15. The waste box 14 can be opened by separating the fixing bolt 15 from the first connecting ring 6 and the second connecting ring 7, facilitating the processing of impurities inside. Several rubber auxiliary plates 16 are installed on the inner walls of the first connecting ring 6 and the second connecting ring 7. The inner walls of the auxiliary plates 16 are connected to the surface of the valve stem 1, thereby increasing the friction between the first connecting ring 6, the second connecting ring 7, and the valve stem 1, ensuring the stability of the device installation and keeping the shielding net 9 and the water flow channel 4 in a straight line.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
