[0028] Embodiment 1

[0029] As Figure 1 and Figure 2As shown in the figure, this embodiment provides a valve bank 100, which includes a base 110, a first valve 120, a second valve 130, and a third valve 140. The base 110 is in the shape of a cuboid, and a hydrogen inlet 111 and a hydrogen filling port 112 are respectively opened at both ends in the length direction thereof, and a plurality of ventilation ports 113 are opened at its upper end. The hydrogen inlet 111, the hydrogen filling port 112, and the ventilation ports 113 are interconnected. The first valve 120 is a check valve or a pressure reducing valve. One end of the first valve 120 is fixedly connected to the hydrogen inlet 111 by means of threaded connection, flange connection, welding connection, or clamp quick installation connection, etc., and the other end is connected to a downstream hydrogen-consuming device through a pipeline. The second valve 130 is a check valve. One end of the second valve 130 is fixedly connected to the hydrogen filling port 112 by means of threaded connection, flange connection, welding connection, or clamp quick installation connection, etc., and the other end is connected to an upstream hydrogen production device through a pipeline. The third valve 140 is a two-way valve. One ends of the plurality of third valves 140 are respectively fixedly connected to the plurality of ventilation ports 113 in a one-to-one correspondence by means of threaded connection, flange connection, welding connection, or clamp quick installation connection, etc., and the other ends are respectively connected to the bottle valves of the hydrogen storage device through hoses.

[0030] Embodiment Two

[0031] As Figure 3 shown in the figure, this embodiment provides a manifold, which includes a valve bank 100, a hose 200, a bottle valve 300, and a pressure reducing valve 400. The valve bank 100 is as described in Embodiment One. The plurality of bottle valves 300 are respectively connected to the third valves 140 of the valve bank 100 through hoses 200 in a one-to-one correspondence. The bottle valves 300 are used to connect hydrogen storage devices, so that a plurality of hydrogen storage devices are connected to the valve bank 100 through parallel pipelines, enabling the plurality of third valves 140 to control the flow of hydrogen simultaneously or separately, and realizing reasonable distribution of hydrogen flow or special control requirements. One end of the pressure reducing valve 400 is connected to the first valve 120 of the valve bank 100 through a pipeline, and the other end is connected to a downstream hydrogen-consuming device. Since there may be multiple downstream hydrogen-consuming devices and the hydrogen consumption pressures of different hydrogen-consuming devices are different, for example, the pressure of a fuel cell power generation device (hydrogen fuel cell stack) is different from that of a hydrogen energy gas appliance, a plurality of pressure reducing valves 400 can be provided, and the outlet pressure of the pressure reducing valve 400 can be designed according to the required pressure of the downstream hydrogen-consuming device.

[0032] Furthermore, the pressure reducing valve 400 can replace the first valve 120 and be directly integrated into the hydrogen output port 111 of the valve bank 100, that is, the pressure reducing valve 400 and the hydrogen output port 111 are fixedly connected by means of threaded connection, flange connection, welded connection or clamp quick installation connection. When there are multiple hydrogen-consuming devices with different pressure requirements, multiple hydrogen output ports 111 can be provided on the valve bank 100 and directly connected to multiple pressure reducing valves 400 respectively.

[0033] When the manifold is in the hydrogen filling state, hydrogen is filled into the hydrogen storage device via the second valve 130, the third valve 140 and the bottle valve 300; when the manifold is in the hydrogen discharging state, hydrogen flows to the hydrogen-consuming device via the bottle valve 300, the third valve 140, the first valve 120 and the pressure reducing valve 400.

[0034] Embodiment 3

[0035] This embodiment provides a hydrogen input and output system, including the manifold as described in Embodiment 2.

[0036] In summary, the valve bank 100 of the present utility model adopts a parallel design with multiple independently controlled third valves 140 integrated on a single base, which can simplify the pipeline between the valves of the valve bank, occupy less overall space, and make daily maintenance and component replacement simple. It can distribute fluids such as hydrogen according to preset ratios and paths, and can transport hydrogen to multiple different paths simultaneously to achieve reasonable distribution of hydrogen flow; multiple third valves 140 can be opened or closed separately as needed, and the opening degree or switching sequence of different valves can be adjusted, so as to achieve precise control of fluid flow according to actual needs and implement complex flow control strategies, such as proportional distribution, timed path switching or pressure regulation, etc.; in addition, since each third valve 140 works independently, this means that even if one of the third valves needs to be temporarily closed due to failure or maintenance, the other valves can still continue to operate, ensuring that the normal operation of the overall manifold is not affected, and significantly improving the overall reliability and safety.

[0037] Therefore, the present utility model effectively overcomes various disadvantages in the prior art and has high industrial utilization value. The above embodiments are only illustrative of the principles and effects of the present utility model and are not used to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
