Technical Field

[0001] The present application relates to the field of valves, and in particular to a solid-state hydrogen storage bottle mouth valve for an electric two-wheeled vehicle. Background Art

[0002] With the continuous development of clean energy, people hope to use cleaner and more efficient power devices. Existing fuel cells generate electricity through the chemical reaction of hydrogen and oxygen, making them a clean and efficient power device. Electric two-wheeled vehicles also operate on electricity. When technicians use fuel cell systems as the power device of electric two-wheeled vehicles, the bottle valve storing solid hydrogen will be integrated with a one-way valve, installation valve, pressure reducing valve, manual valve and other components to control the sealing, on-off and pressure reduction functions of the hydrogen fuel. However, existing manual valves have a short service life, poor sealing, and are prone to leakage. In addition, the on-off control of the pipeline is manually implemented, which increases the difficulty of operation. Utility Model Content

[0003] In order to facilitate the on-off control of the system pipeline and improve the sealing performance of the valve, the present application provides a solid hydrogen storage bottle mouth valve for an electric two-wheeled vehicle.

[0004] This application provides a solid-state hydrogen storage bottle mouth valve for an electric two-wheeled vehicle, which adopts the following technical solution:

[0005] A solid-state hydrogen storage bottle mouth valve for an electric two-wheeled vehicle includes an integrated seat and a solenoid valve arranged on the integrated seat and used to control the opening and closing of the integrated seat outlet. The solenoid valve includes a valve sleeve arranged on the integrated seat, a main valve core, a secondary valve core and a solenoid assembly arranged in the valve sleeve. The main valve core is provided with an air outlet connected to the integrated seat outlet. The secondary valve core controls the opening and closing of the air inlet end of the air outlet. The main valve core is provided with a pressure equalizing channel running through the main valve core. The pressure equalizing channel is used to connect the cavity above the main valve core and the air inlet of the integrated seat. A seal is provided between the main valve core and the valve sleeve. The seal is used to seal the gap between the main valve core and the valve sleeve.

[0006] By adopting the above technical solution, the solenoid valve is convenient for controlling the on-off of the pipeline, and the integrated seat is used to install other types of valves. When the power is on, the electromagnetic assembly drives the auxiliary valve core to move. After the auxiliary valve core is opened, the main valve core moves upward under the action of the medium force to open the integrated seat outlet. A pair of seals seal the gap between the valve sleeve and the main valve core, thereby improving the air pressure stability of the air intake path and avoiding the solenoid valve from releasing pressure, which leads to the instability of the movement of the main valve core. The electromagnetic assembly facilitates the solenoid valve to control the on-off of the gas.

[0011] Preferably, the integrated seat is provided with a fixing member located between the valve sleeve and the main valve core, and a second sealing member is provided between the fixing member and the integrated seat.

[0012] By adopting the above technical solution, the second sealing member improves the sealing between the main valve core and the integrated seat, thereby improving the sealing performance of the solenoid valve.

[0013] Preferably, a protrusion is provided on the side of the second sealing member facing the main valve core.

[0014] By adopting the above technical solution, the protrusion further increases the contact area between the second sealing member and the main valve core, thereby improving the sealing effect of the second sealing member on the main valve core and the integrated seat.

[0015] Preferably, a positioning seat for positioning the valve sleeve is provided on the integrated seat, and a sealing ring 1 is provided between the valve sleeve and the positioning seat.

[0016] By adopting the above technical solution, the positioning seat improves the stability of the valve sleeve on the integrated seat, and the sealing ring improves the connection sealing between the valve sleeve and the positioning seat.

[0017] Preferably, a discharge port is provided on the integrated seat, and a safety valve for controlling the opening and closing of the discharge port is provided on the integrated seat.

[0018] By adopting the above technical solution, the safety valve improves the safety of the bottle mouth valve in use, and the discharge port is used for discharging hydrogen when the hydrogen pressure exceeds the safety valve action pressure.

[0019] Preferably, the integrated seat is provided with a pressure reducing valve for controlling the outlet pressure.

[0020] By adopting the above technical solution, the pressure reducing valve reduces the hydrogen pressure to the required pressure.

[0021] Preferably, the inlet of the integrated seat is provided with a one-way valve.

[0022] By adopting the above technical solution, the one-way valve is used for gas intake of the gas cylinder, making it easy to inflate the gas cylinder.

[0025] To sum up, the solenoid valve is convenient for controlling the on-off of the pipeline. The first seal improves the airtightness of the solenoid valve and ensures the smooth operation of the main valve core. The second seal improves the sealing between the main valve core and the integrated seat to avoid air leakage in the solenoid valve and ensure the sealing effect of the solenoid valve on the integrated seat. The solenoid valve is integrated into the bottle mouth of the gas cylinder through the integrated seat, which is convenient for subsequent control of the on-off of the pipeline and reduces the possibility of hydrogen leakage caused by human operation errors.

[0031] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0032] The embodiment of the present application discloses a solid hydrogen storage bottle mouth valve for electric two-wheeled vehicles. Figure 1 The integrated seat 1 includes an integrated seat 1 and a solenoid valve 2 mounted on the integrated seat 1. A connecting seat 16 is fixedly mounted on the side of the integrated seat 1 facing the gas cylinder 18. The connecting seat 16 is threadedly connected to the bottle mouth of the gas cylinder 18 to facilitate installation and removal of the integrated seat 1. To improve the sealing effect between the integrated seat 1 and the gas cylinder 18, a second sealing ring 17 is installed between the connecting seat 16 and the gas cylinder 18. In the embodiment of the present application, the second sealing ring 17 is an O-ring.

[0033] Reference Figure 1 and Figure 2 The integrated seat 1 is provided with an inlet 19, and a one-way valve 15 is installed on the integrated seat 1 at the inlet 19. When the gas in the gas cylinder 18 is exhausted, the inlet 19 is used for inflation. The one-way valve 15 effectively prevents gas backflow when the gas cylinder 18 is inflated. The integrated seat 1 is provided with an air inlet 25 connected to the solenoid valve 2. When the fuel cell system is working, the hydrogen in the gas cylinder 18 enters from the air inlet 25 and is turned on and off by the solenoid valve 2. When the power is on, the solenoid valve 2 is opened, and the integrated seat 1 is provided with an outlet 20 for hydrogen to flow out. The integrated seat 1 is provided with a pressure reducing valve 14. The pressure reducing valve 14 is located at the outlet end of the solenoid valve 2 and is used to reduce the pressure of the outflowing hydrogen to the required pressure before it flows to the outlet 20. In order to improve the safety of the use of the gas cylinder 18, a safety valve 13 is installed on the integrated seat 1. The safety valve 13 is connected to the hydrogen pressure in the gas cylinder 18. A discharge port 12 is opened on the integrated seat 1. When the hydrogen pressure in the gas cylinder 18 exceeds the operating pressure of the safety valve 13, the safety valve 13 will be triggered to open, and the hydrogen will be discharged through the discharge port 12, thereby ensuring the safety of the gas cylinder 18.

[0034] Reference Figure 1 and Figure 3 In this application, the solenoid valve 2 is used to control the hydrogen flow in the gas cylinder 18. The solenoid valve 2 includes a valve sleeve 21 provided on the integrated seat 1, a main valve core 22 located in the valve sleeve 21, a secondary valve core 23, and an electromagnetic assembly 24 installed on the valve sleeve 21 and used to control the movement of the secondary valve core 23. A positioning seat 10 for positioning the valve sleeve 21 is fixedly installed on the integrated seat 1. In the embodiment of this application, the positioning seat 10 and the integrated seat 1 are integrally formed to improve the stability of the positioning seat 10 on the integrated seat 1. In order to improve the sealing between the valve sleeve 21 and the positioning seat 10, a sealing ring 11 is provided between the valve sleeve 21 and the positioning seat 10. In the embodiment of this application, the sealing ring 11 is an O-ring. An air outlet 3 connected to the outlet 20 of the integrated seat 1 is provided on the main valve core 22. The secondary valve core 23 is located at the air inlet end of the air outlet 3. The electromagnetic assembly 24 controls the movement of the secondary valve core 23 to control the flow of the air outlet 3.

[0035] Reference Figure 3 and Figure 4The main valve core 22 is provided with a pressure equalizing channel 4 along the axial direction, and the two ends of the pressure equalizing channel 4 are respectively connected to the top and bottom of the main valve core. A fixing part 6 is provided on the integrated seat 1, which is located between the valve sleeve 21 and the main valve core. A gas circulation channel 1 is formed between the fixing part 6 and the valve sleeve 21, and the channel 1 is connected to the air inlet 25. The gas enters the channel 1 from the air inlet 25, and then enters the pressure equalizing channel 4 from the channel 1, and flows out from the pressure equalizing channel 4 toward the end of the auxiliary valve core 23. When the auxiliary valve core 23 is opened, the gas flows out from the end of the pressure equalizing channel 4 into the air inlet end of the air outlet 3, forming an air source path a. In order to ensure the air tightness between the main valve core 22 and the integrated seat 1 when the solenoid valve 2 is closed, a sealing part 5 is provided between the main valve core 22 and the valve sleeve 21. The sealing part 5 is used to seal the gap between the main valve core 22 and the valve sleeve 21, to ensure the medium travel path, ensure the medium force balance, and improve the response speed of the solenoid valve 2.

[0036] Reference Figure 3 and Figure 4 The electromagnetic assembly 24 includes a coil 241 arranged on the valve sleeve 21, a push rod 242 arranged in the valve sleeve 21, a stop iron 243 mounted on the push rod 242, a secondary spring 244 with one end mounted on the push rod 242 and the end located in the stop iron 243, an armature 245 mounted on the push rod 242 and located at one end of the push rod 242 facing the main valve core 22, and a main spring 246 mounted on the armature 245. The secondary valve core 23 is located on the side of the armature 245 facing the main valve core 22.

[0037] Reference Figure 3 and Figure 4 , the coil 241 is energized, and the armature 245 is attracted to the stopper 243 by the electromagnetic force. At this time, the auxiliary valve core 23 is driven by the armature 245, thereby opening the air outlet 3; at this time, the gas source enters the air outlet 3 from the equalizing pressure channel 4, and the gas source movement path is a. After the auxiliary valve core 23 is opened, the gas enters the equalizing pressure channel 4 from the air inlet 25, and then enters the upper cavity of the main valve core 22 from the equalizing pressure channel 4. During the gas flow, there is an upward medium force on the main valve core 22, and the main valve core 22 moves upward under the action of this medium force. Thus, the valve port of the main valve core 22 is opened. When the main valve core 22 moves upward, it pushes the guide rod to drive the armature 245 and the stopper 243 to move together, and compresses the auxiliary spring 244 until the displacement upper limit of the main valve core 22 is reached. At this time, the gas enters the gas source from the air inlet 25 and moves along the path b. When the coil 241 is de-energized, the auxiliary valve core 23 moves downward under the spring force of the auxiliary spring 244, closing the air outlet 3 of the main valve core 22. The main valve core 22 moves downward under the spring force of the main spring 246, closing the valve port of the main valve core 22.

[0038] Reference Figure 2To improve the seal between the main valve core 22 and the integrated seat 1, a second seal 8 is provided between the main valve core 22 and the integrated seat 1. This seal 8 is used to press the main valve core 22 downward to close the air source movement path b, thereby improving the seal between the main valve core 22 and the integrated seat 1. A protrusion 9 is provided on the side of the second seal 8 facing the main valve core 22. This protrusion 9 is an annular protrusion extending from the surface of the second seal 8 toward the main valve core 22. This protrusion 9 ensures closer contact between the second seal 8 and the main valve core 22, improving the sealing effect of the second seal 8.

[0039] Reference Figure 3 and Figure 4 Seal 1-5 is a Y-shaped seal ring. Compared to conventional O-rings, Y-shaped seal rings offer superior sealing performance, low friction, and smooth movement in reciprocating motion. A positioning ring 7 is sleeved around the main valve core 22. Positioning ring 7 is located on the side of seal 1-5 axially away from the auxiliary valve core 23 and serves to limit the position of seal 1-5 and improve its stability.

[0040] The implementation principle of a solid-state hydrogen storage bottle mouth valve for an electric two-wheeled vehicle in the embodiment of the present application is as follows: the integrated seat 1 is threadedly connected to the bottle mouth of the gas cylinder 18 through the connecting seat 16, and the sealing ring 17 seals the gap between the gas cylinder 18 and the connecting seat 16 to improve the airtightness between the integrated seat 1 and the gas cylinder 18. When the gas cylinder 18 needs to be inflated, the external hydrogen enters the integrated seat 1 through the inlet 19 and enters the gas cylinder 18. The one-way valve 15 effectively ensures the airtightness of the inlet 19 and reduces the possibility of hydrogen leakage. The seal 1 5 is used to improve the sealing between the main valve core 22 and the valve sleeve 21, ensure the sealing of the medium travel path, ensure the balance of medium force, and improve the response speed of the solenoid valve 2. The seal 2 8 improves the sealing between the main valve core 22 and the integrated seat 1, and improves the overall sealing effect of the solenoid valve 2.

[0041] In the operating state, solenoid valve 2 is energized and opens, allowing hydrogen to flow through solenoid valve 2 and pressure reducing valve 14 to outlet 20. Safety valve 13 always maintains communication with the hydrogen pressure in gas cylinder 18. When the hydrogen pressure exceeds the operating pressure of safety valve 13, safety valve 13 opens, discharging hydrogen from discharge port 12, ensuring the safety of gas cylinder 18.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
