Another core aspect of this application is to provide an on-board hydrogen system including the aforementioned integrated hydrogen supply valve.

[0033] This application provides an integrated hydrogen supply valve, including a valve body 1 and a pressure reducing valve assembly 2.

The control component can be pulled out of the first valve port 15 and the second valve port 16. The pressure reducing valve assembly 2 is located inside the valve body 1 and is located between the high-pressure channel 11 and the low-pressure channel 12. The inlet of the pressure reducing valve assembly 2 is connected to the second end of the high-pressure channel 11, and the outlet of the pressure reducing valve assembly 2 is connected to the second end of the low-pressure channel 12 to reduce the pressure of the gas in the high-pressure channel 11 and transfer it to the low-pressure channel 12.

[0034] Please refer to Figure 1 The valve body 1 has a hollow structure, with a high-pressure channel 11 and a low-pressure channel 12 inside.

The pressure reducing valve assembly 2 can receive high-pressure gas from the high-pressure channel 11, pressurize it, and then output it to the low-pressure channel 12. Therefore, this integrated hydrogen supply valve has the function of releasing compressed gas to supply gas to gas-consuming equipment.

The corresponding control components are connected to the first valve port 15 and the second valve port 16 to realize the regulation of the gas in the high-pressure channel 11 and the low-pressure channel 12.

[0035] When using this integrated hydrogen supply valve, if the control components need to be repaired, the corresponding component can simply be pulled out from the corresponding opening in the valve body 1. Furthermore, the risk of leakage using this integrated hydrogen supply valve is low.

For example, there are three air inlets 13 and three air outlets 14, or two air inlets 13 and four air outlets 14, etc., to ensure gas supply capacity and meet the gas demand of several gas-using devices. Thus, the integrated hydrogen supply valve has hydrogen inlet and hydrogen supply expansion capabilities.

[0039] Based on the above embodiment, several air outlets 14 are all connected to a switching valve 3, which is located outside the valve body 1. Please refer to [reference needed]. Figure 1 When in use, the control switch valve 3 is opened when the corresponding gas outlet 14 needs to be opened. With this setting, the integrated hydrogen supply valve is easy to use.

[0040] Based on the above embodiments, it also includes several interconnected plugs, which can be inserted into the air inlet 13, air outlet 14, first valve port 15 and second valve port 16 to open or close the air inlet 13, air outlet 14, first valve port 15 and second valve port 16 respectively.

[0041] Please refer to Figure 1 The integrated hydrogen supply valve assembly is equipped with several plugs, which can be selected as needed to close unused inlet 13 and / or first valve port 15 and / or second valve port 16 and / or outlet 14 using plugs. Unused outlets can be closed by plugs or manual ball valves.

[0043] Please refer to Figure 1To regulate the gas pressure in the high-pressure channel 11 and the low-pressure channel 12, the inlet of the high-pressure manual relief valve 4 is connected to a first valve port 15 on the valve body 1, and the inlet of the low-pressure manual relief valve 5 is connected to a second valve port 16 on the valve body 1. When the gas pressure in the high-pressure channel 11 and the low-pressure channel 12 of the valve body 1 is too high, the high-pressure manual relief valve 4 and the low-pressure manual relief valve 5 are opened, thereby realizing gas pressure regulation and control, and improving the operating efficiency and stability of the system using this integrated hydrogen supply valve.

[0044] It should be noted that there are no restrictions on how the first valve port 15 and the second valve port 16 are connected to the control component. For example, the terminals of the control component can be directly inserted into the first valve port 15 or the second valve port 16, or the air intake pipe can be connected to the terminals of the control component and the air intake pipe can be inserted into the first valve port 15 or the second valve port 16, etc.

When the gas pressure in the high-pressure channel 11 and the low-pressure channel 12 of the valve body 1 reaches the upper limit of the safety gas pressure, the high-pressure safety relief valve 6 and the low-pressure safety relief valve 7 will automatically open. When the gas pressure in the high-pressure channel 11 and the low-pressure channel 12 of the valve body 1 drops to the allowable value, the high-pressure safety relief valve 6 and the low-pressure safety relief valve 7 will automatically close. This integrated hydrogen supply valve can automatically prevent accidents that may occur due to overpressure.

[0047] Based on the above embodiments, the control component also includes a one-way valve 8, which is connected to another first valve port 15 so that gas in the high-pressure channel 11 can be discharged, and the one-way valve 8 is located outside the valve body 1.

[0048] Please refer to Figure 1 To ensure sufficient gas supply, the outlet of a check valve 8 is connected to another first valve port 15 on the valve body 1. When the gas pressure in the high-pressure channel 11 of the valve body 1 is difficult to reach the predetermined gas pressure, the inlet of the check valve 8 is connected to the hydrogen supply pipeline. Opening the check valve 8 allows gas to be added to the high-pressure channel 11, thereby further improving the hydrogen supply expansion capability of the integrated hydrogen supply valve.

[0049] Based on the above embodiments, the control component further includes a pressure sensor 9, which is electrically connected to another second valve port 16, and the pressure sensor 9 is located outside the valve body 1.

When in use, the switch valve 3 connected to several outlets 14 is opened. The gas in the gas storage device flows sequentially through the inlet 13, inlet channel 18, high-pressure channel, pressure reducing valve assembly 2, low-pressure channel 12, outlet 14, and switch valve 3 into the gas-using device, thereby improving the smoothness of gas flow.
