Embodiment Construction
[0052] In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details. In other examples, some technical features known in the art are not described in order to avoid confusion with the present invention.
[0053] In the present invention, the moving objects mainly refer to various moving objects that use fuel cells as the power system to drive on the road, including but not limited to vehicles, airplanes, ships and other moving objects. The present invention takes hydrogen fuel electric bicycles as an example Discuss. refer to figure 1 , is the structural intention of the hydrogen storage device and its wiring in the prior art; various functional valves 400 in the prior art are used as independent bodies, one end is connected to the hydrogen storage bottle 200 t...

The invention discloses a hydrogen storage device combination valve for a moving object and a control method of the hydrogen storage device combination valve, and belongs to the field of energy equipment. The combination valve comprises a valve body, a connecting hole, which communicates with a gas outlet of a hydrogen storage bottle and is used for conveying hydrogen into the valve body, a ventilation opening which communicates with the connecting hole, receives hydrogen gas and transmits the hydrogen gas to the hydrogen storage bottle, and / or transmits the hydrogen gas to an electric pile, a control valve which is arranged on a connecting point of the ventilation opening and the connecting hole and is used for controlling opening and closing of a passage between the connecting hole and the ventilation opening, a safety valve which communicates with the connecting hole, so that the internal pressure of the hydrogen storage bottle is controlled in a low-pressure range of 1-3MPa, and a pressure regulating valve which is arranged on a passage between the connecting hole and the ventilation opening and is used for controlling the air pressure in the valve body. According to the hydrogen storage device combination valve disclosed by the invention, a sealing connector is connected to the gas outlet, when the hydrogen storage device is transported and replaced, a first connector is in an open-circuit state, the gas outlet of the combination valve is automatically closed, gas tightness of the combination valve is improved, hydrogen leakage amount is further reduced, and the hydrogen storage device is rapidly and conveniently replaced.
Description
technical field [0001] The invention belongs to the field of energy equipment, in particular to a hydrogen storage combined valve for moving objects and a control method thereof. Background technique [0002] It is quite common to use a hydrogen storage tank as a storage device for hydrogen. Whether it is a hydrogen fuel cell system or other products using hydrogen fuel cells, it is necessary to supply hydrogen. At present, hydrogen storage technologies can be mainly divided into three types: high-pressure gas, liquid hydrogen, and hydrogen storage alloys. Among them, high-pressure gas hydrogen storage has higher energy, weight, and density, but is larger in size and less safe. Although the energy, weight, and density of the liquid hydrogen storage method are relatively high, the liquefaction energy consumption is large, and an insulated storage tank must be used at the same time, which is generally suitable for large storage tanks; the energy, weight, and density of the hyd...
