Abstract
Description
Technical Field
[0001] This application relates to the field of solenoid valve pistons, and more particularly to a solenoid valve piston assembly with a buffer function. 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 widely used in industrial automation, hydraulic / pneumatic systems, and home appliances. The solenoid valve uses the magnetic field generated by energizing an electromagnetic coil to drive internal mechanical components, thereby opening, closing, or switching the flow direction of fluid. Its core functions include rapid response to electrical signals, suitability for automated control and regulation of media direction, flow rate, or pressure, and support for both gases and liquids. The solenoid valve piston is a key component; it uses the electromagnetic force generated by the electromagnetic coil to drive the valve's opening and closing, thus controlling fluid flow. The solenoid valve piston mainly consists of the valve core and piston rings. The valve core is a cylindrical component that controls the flow of fluid through electromagnetic force, while the piston rings are responsible for sealing and preventing media leakage.
[0003] Regarding the aforementioned technologies, the inventors believe that after installation, conventional solenoid valve pistons are affected by various factors, such as the water pressure connected to the solenoid valve. When used in locations with high water pressure, the opening and closing of the solenoid valve can easily lead to significant pressure changes around the pipe connected to the solenoid valve, causing the solenoid valve to shake. After prolonged use, this can easily cause the solenoid valve to loosen, thus affecting the sealing effect of the piston position.
[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

The two drain pipes are symmetrically distributed about the branch pipe.
[0008] Preferably, a plurality of rotating plates are rotatably installed on the inner wall of the branch pipe.

[0010] Preferably, a water pressure detector is fixedly connected to the top of the water inlet pipe, and the water pressure detector is vertically positioned between the water inlet pipe and the water inlet pipe.

By installing a connecting pipe on the surface of the solenoid valve core, one end of the connecting pipe is connected to the inlet pipe via a branch pipe, and the other end is connected to the drain pipe, so as to connect to the water source via the inlet pipe.

Several rotating plates are rotatably installed on the inner wall of the branch pipe, and push springs are installed on the surface of the rotating plates, so as to reduce the water pressure with the help of the rotating plates and the branch pipe.

Detailed Implementation
[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0023] This application discloses a solenoid valve piston assembly with a buffer function, referring to... Figure 1 - Figure 2 The system includes a solenoid valve core 1 and a solenoid valve piston, which are mainly composed of the solenoid valve core 1 and piston rings. The solenoid valve core 1 is a cylindrical component that controls the flow of fluid through electromagnetic force. The piston rings are responsible for sealing and preventing media leakage. A connecting pipe 3 is installed on the surface of the solenoid valve core 1. One end of the connecting pipe 3 is connected to a branch pipe 4, and one end of the branch pipe 4 is connected to a water inlet pipe 5. The other end of the connecting pipe 3 is connected to a drain pipe 6. The system connects to a water source through the water inlet pipe 5. After the water flows into the water inlet pipe 5, it is diverted through the branch pipe 4, thereby distributing the impact force of the water flow. This effectively improves the stability of the solenoid valve piston after installation and avoids the problem of the solenoid valve core 1 becoming loose due to excessive water pressure.
[0024] Reference Figure 2Several rotating plates 7 are rotatably installed on the inner wall of the branch pipe 4. Push springs 8 are installed on the surface of the rotating plates 7. One end of the push spring 8 is connected to the inner wall of the branch pipe through a fixing block 9. The rotating plates 7 block the incoming water flow, and control the rotating plates 7 to open when the water flow pressure is greater than the spring thrust, thereby reducing the water flow pressure in conjunction with the branch pipe 4. A limit block 10 is installed on the inner wall of the branch pipe 4. One end of the limit block 10 is connected to the surface of the rotating plate 7. The limit block 10 blocks one end of the rotating plate 7, preventing the rotating plate 7 from being pushed too much by the spring. A water pressure detector 11 is installed on the top of the inlet pipe 5. The water pressure detector 11 detects the water flow in the inlet pipe 5, making it convenient for the user to control the flow rate.
[0025] Reference Figure 3 - Figure 4 Two rotating blades 12 are installed inside the connecting pipe 3. A rotating disk 13 is installed at one end of the rotating blade 12. A speed reduction block 14 is movably connected to the surface of the rotating disk 13. The speed reduction block 14 is connected to the surface of the rotating disk 13 to restrict the rotating blade 12 and slow down the water flow in the inlet pipe 5. An electric push rod 15 is installed at one end of the speed reduction block 14. One end of the electric push rod 15 is connected to the surface of the inlet pipe 5. The speed reduction block 14 is moved by adjusting its own length, so as to control the speed reduction force of the speed reduction block 14 on the rotating disk 13 and the rotation speed of the rotating blade 12. Several auxiliary grooves 16 are opened on the surface of the rotating disk 13. The auxiliary grooves 16 increase the friction between the rotating disk 13 and the speed reduction block 14, thereby ensuring the speed reduction effect of the speed reduction block 14 on the rotating disk 13.
[0026] The implementation principle of a solenoid valve piston assembly with buffer function in this application embodiment is as follows: A connecting pipe 3 is installed on the surface of the solenoid valve core 1. One end of the connecting pipe 3 is connected to a branch pipe 4, and one end of the branch pipe 4 is connected to a water inlet pipe 5. One end of the connecting pipe 3 is connected to a drain pipe 6, so as to connect to a water source through the water inlet pipe 5. After the water flows into the water inlet pipe 5, it is diverted through the branch pipe 4, thereby distributing the impact force of the water flow and avoiding the problem of the solenoid valve core 1 being loosened due to excessive water pressure. Several rotating plates 7 are rotatably installed on the inner wall of the branch pipe 4. Push springs 8 are installed on the surface of the rotating plates 7. One end of the push spring 8 is connected to a drain pipe 6. The fixing block 9 is connected to the inner wall of the diversion pipe so that the rotating plate 7 can block the incoming water flow. When the water flow pressure is greater than the spring thrust, the rotating plate 7 is controlled to open, thereby reducing the water flow pressure in conjunction with the diversion pipe 4. The inner wall of the diversion pipe 4 is equipped with a limit block 10. One end of the limit block 10 is connected to the surface of the rotating plate 7 so that one end of the rotating plate 7 can be blocked by the limit block 10, avoiding the problem of the rotating plate 7 being pushed too much by the spring. A water pressure detector 11 is installed on the top of the water inlet pipe 5 so that the water flow in the water inlet pipe 5 can be detected by the water pressure detector 11, making it convenient for the user to control the flow rate of the water.
[0027] Two rotating blades 12 can also be installed inside the connecting pipe 3. A rotating disk 13 is installed at one end of the rotating blade 12. A speed reduction block 14 is movably connected to the surface of the rotating disk 13 so that the rotating blade 12 can be restricted by the connection between the speed reduction block 14 and the surface of the rotating disk 13, thereby slowing down the water flow in the water inlet pipe 5. An electric push rod 15 is installed at one end of the speed reduction block 14. One end of the electric push rod 15 is connected to the surface of the water inlet pipe 5 so that the speed reduction block 14 can be moved by adjusting its own length, thereby facilitating the control of the speed reduction force of the speed reduction block 14 on the rotating disk 13 and the rotation speed of the rotating blade 12. Several auxiliary grooves 16 are opened on the surface of the rotating disk 13 so as to increase the friction between the rotating disk 13 and the speed reduction block 14 by means of the auxiliary grooves 16, thereby ensuring the speed reduction effect of the speed reduction block 14 on the rotating disk 13.
