Similar terms such as "a", "an", or "the" used in the present utility model also do not represent a quantity limitation but only indicate the existence of at least one.

The term "comprising", "including", or any other variant thereof is intended to cover non-exclusive inclusion, and in addition to the listed elements, it may also include other elements not explicitly listed.

[0026] To avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0027] Embodiment 1

[0028] As Figure 1 shown, the present utility model provides a bus bar, which includes a pressure reducing valve 10, a first multi-way valve 20, a second multi-way valve 30, and a bottle valve 40. The outlet 111 (see Figure 2 ) of the pressure reducing valve 10 is communicated with a hydrogen output port 52, and the hydrogen output port 52 is connected to a downstream hydrogen-using device; the first multi-way valve 20 is respectively communicated with a hydrogen filling port 51, the second multi-way valve 30, and the inlet of the pressure reducing valve 10, and the hydrogen filling port 51 is connected to an upstream hydrogen production device; the second multi-way valve 30 is communicated with the bottle valve 40, and the bottle valve 40 is used to connect a hydrogen storage device.

[0029] When the bus bar is in the hydrogen filling state, hydrogen is filled into the hydrogen storage device via the hydrogen filling port 51, the first multi-way valve 20, the second multi-way valve 30, and the bottle valve 40; when the bus bar is in the hydrogen discharging state, hydrogen flows from the outlet 111 of the pressure reducing valve 10 to the hydrogen-using device via the bottle valve, the second multi-way valve 30, the first multi-way valve 20, and the pressure reducing valve 10.

[0030] It should be understood that although not shown in the figure, one of the second multi-way connectors 30 can also be connected in series with other second multi-way connectors 30 to meet the connection requirements of a larger number of the bottle valves 40. However, it should be noted that the multiple second multi-way valves 30 communicated with the first multi-way valve 20 are not directly connected.

[0031] Specifically, the main structural form of the pressure reducing valve 10 can be a bellows type pressure reducing valve, a diaphragm type pressure reducing valve, a piston type pressure reducing valve, etc., which are conventional pressure reducing valves in the art, and the specific structure will not be elaborated here. The pressure reducing valve 10 can reduce the outlet pressure of the pipeline to the intake pressure that the hydrogen-using equipment can bear and, relying on its own energy, automatically keep the outlet pressure stable.

[0032] In this embodiment, both the first multi-way valve 20 and the second multi-way valve 30 are six-way valves, but this is not necessary. The second multi-way valve 30 can also be a three-way valve, a four-way valve, a five-way valve, an eight-way valve, etc. The first multi-way valve 20 can also be a four-way valve, a five-way valve, an eight-way valve or other multi-way valves with more than three passages to ensure that after the first multi-way valve 20 connects one hydrogen filling port 51 and two hydrogen output ports 52, it can still be connected to at least one second multi-way valve 30. The two hydrogen output ports 52 can be respectively connected to a fuel cell power generation device and a hydrogen energy gas appliance. The number of passages of the first multi-way valve 20 and the second multi-way valve 30 can also be different. Since the multi-way valve is a mature market product, its structure will not be elaborated here.

[0033] By adopting the combined design of the above-mentioned first multi-way valve 20 and second multi-way valve 30, problems existing in the existing manifold such as a large number of components, large space occupation, cumbersome daily maintenance and component replacement can be solved.

[0034] Furthermore, as Figure 2 shown, the first multi-way valve 20 can be integrally integrated with the pressure reducing valve 10. Specifically, the first multi-way valve 20 is integrally integrated with the valve seat 13 of the pressure reducing valve 10. The valve body 11 of the pressure reducing valve 10 is connected to the valve seat 13 through an opening and closing slider 12. When the manifold is in the hydrogen filling state, the valve body 11 disengages from the opening and closing slider 12, and hydrogen is filled into the hydrogen storage device through the hydrogen filling port 51, the first multi-way valve 20, the second multi-way valve 30 and the bottle valve 40; when the manifold is in the hydrogen discharging state, the valve body 11 presses against the opening and closing slider 12, and hydrogen flows from the outlet 111 of the pressure reducing valve 10 to the hydrogen using device through the bottle valve, the second multi-way valve 30, the first multi-way valve 20 and the pressure reducing valve 10.

[0035] In this embodiment, the valve seat 13 of the pressure reducing valve 10 is ingeniously integrated with the first multi-way valve 20. This integration scheme can further streamline the number of components, optimize the space utilization at the same time, make the overall system structure more compact, not only save the precious installation area, but also improve the overall layout efficiency of the system. At the same time, due to the reduction of the number of components, daily maintenance and component replacement become more convenient, greatly saving the subsequent operation cost and time. In addition, the integrated design idea further simplifies the installation process, significantly reducing the installation steps and potential connection links. This not only significantly reduces the installation cost, but also effectively reduces the error probability caused by human factors, making the system more smooth during the initial deployment.

[0036] From a performance perspective, the integrated design greatly enhances the overall operating efficiency and reliability of the system by eliminating connection points and potential leakage sources. It reduces energy losses during hydrogen transmission, ensuring stable operation of the system even under high loads. At the same time, this design endows the system with higher flexibility and convenience, meeting the diverse needs in different application scenarios.

[0037] Particularly noteworthy is that the valve seat 13 of the pressure reducing valve 10 in the integrated solution plays a crucial role. It can accurately regulate the pressure when hydrogen passes through, ensuring that downstream equipment always operates within a safe pressure range, avoiding equipment damage or safety accidents caused by pressure fluctuations. This function is crucial for ensuring the safety and continuity of hydrogen supply. And the first multi-way valve 20 adds additional functionality to the system. It provides multiple inlet and outlet ports, allowing hydrogen to be freely distributed or converged in different directions, greatly enhancing the versatility and adaptability of the system. Whether it is necessary to supply gas to multiple terminal devices synchronously or achieve flexible switching of hydrogen sources, the first multi-way valve 20 can easily handle it, ensuring the efficiency and accuracy of hydrogen transmission.

[0038] In summary, the first multi-way valve 20 can be integrally designed with the pressure reducing valve 10, not only achieving optimization in physical structure, but also reaching a new height in functionality and safety, setting an example for the upgrade of the hydrogen manifold system.

[0039] Embodiment 2

[0040] As Figure 3 shown, this embodiment provides a hydrogen energy input and output control system, including the manifold provided in the above Embodiment 1, and further including a cold and hot circulation device 60, a temperature sensor 70, and a pressure sensor 80.

[0041] The cooling and heating cycle device 60 is used to cool or heat the cooling and heating cycle cavity where the hydrogen storage device is disposed, so as to improve the hydrogen storage and hydrogen release efficiency and ensure that the temperature is within a reasonable range during the hydrogen charging and discharging processes. The cooling and heating cycle device 60 can be an air-cooled electric heating device, and specifically includes a compressor 61, a filter, a capillary tube, a condenser, an evaporator, an evaporator fan 62, and a heating wire 63. The compressor 61, the filter, the capillary tube, and the condenser are installed outside the cooling and heating cycle cavity; the evaporator, the evaporator fan 62, and the heating wire 63 are disposed inside the cooling and heating cycle cavity; the heating wire 63 can be wound on a winding frame inside the cooling and heating cycle cavity and is arranged around the periphery of the hydrogen storage device. When the hydrogen storage device stores hydrogen, cooling is started, and the compressor 61, the filter, the capillary tube, the condenser, and the evaporator fan 62 participate in the cooling. Its cooling principle is similar to that of an air conditioner and will not be elaborated here. When the hydrogen storage device releases hydrogen, heating is started, and the heating wire 63 participates in the heating. Further, in order to enhance the heating effect, the evaporator fan 62 also participates in the heating.

[0042] The temperature sensor 70 is disposed inside the cooling and heating cycle cavity and is communicatively connected to the cooling and heating cycle device 60 for monitoring the temperature inside the cooling and heating cycle cavity in real time. Heating temperature thresholds and cooling temperature thresholds are preset in the cooling and heating cycle device 60 to ensure that the temperature inside the cooling and heating cycle cavity is maintained within the threshold range during the hydrogen charging and discharging processes of the hydrogen storage device.

[0043] The pressure sensor 80 is disposed near the hydrogen charging port 51 and can also be disposed at other positions in the system. It is used to monitor the pressure change of hydrogen in the pipeline in real time to ensure the safe operation of the system. Specifically, in three states of hydrogen charging, hydrogen discharging, and idle non-operation, the pressure sensor 80 monitors the pressure change of hydrogen. For example, during hydrogen charging, when the pressure reaches a first preset value, the hydrogen production device stops working because a higher pressure will damage the hydrogen production device. After some hydrogen is absorbed by the hydrogen storage alloy in the hydrogen storage device and the pressure slowly decreases, when the pressure drops to a second preset value, the hydrogen production device is restarted. Another example is during hydrogen discharging. If it is monitored that the pressure is low, it means that the hydrogen release flow rate is small, indicating that the hydrogen release speed of the hydrogen storage alloy in the hydrogen storage device is small and it needs to be heated. At this time, the cooling and heating cycle device 60 performs a heating operation to increase the temperature inside the cooling and heating cycle cavity.

[0044] Therefore, the 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 utility model, and are not intended to limit the utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the 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 utility model should still be covered by the claims of the utility model.
