Problems solved by technology

The restrictor valve is used to cut off the supply of hydrogen in the event of rupture of the hydrogen supply pipeline (referring to the pipeline connecting the hydrogen storage system and the fuel cell system). The valve body can be a mechanical restrictor valve or an electronically controlled solenoid valve, but The cost of setting the restrictor valve separately is relatively high, and it needs to increase the space required for installing the restrictor valve separately, which is not conducive to the overall layout, and there is room for improvement

Embodiment Construction

[0029] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0030] The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0031] Such as figure 1 As shown, an overflow valve assembly 100 can automatically close the main shut-off valve 1 when the discharge pressure at the outlet of the storage tank is too low, thereby preventing abnormal leakage of the medium in the storage tank.

[0032] Such as figure 1 As shown, the relief valve assembly 100 according to the embodiment of the present application includes: a main shut-off valve 1 , at least one pressure detector and a control device 2 .

[0033] Such as figure 1 As shown, the main shut-off valve 1 is adapted to be installed at the outlet of the storage tank, and the main shut-off valve 1 is used to selectively discharge the medium in the storage ...

Abstract

A spill valve assembly, a hydrogen storage system, and a fuel cell vehicle are provided. The spill valve assembly includes a main shut-off valve adapted to be mounted at an outlet of a storage tank and for selectively discharging a medium in the storage tank; at least one pressure detector adapted to be mounted at an outlet of the storage tank for detecting a pressure value of the outlet; a control device, wherein the main shut-off valve and the pressure detectors are electrically connected with the control device, and the control device is arranged to control the main shut-off valve to be closed when the pressure value detected by at least one pressure detector is smaller than the set value of the pressure detector. According to the spill valve assembly, the main shut-off valve and the pressure detector are used in cooperation, the pressure at the outlet of the storage tank can be continuously detected, it is guaranteed that the control device can control the main shut-off valve in time, flexibility and applicability are better, and the structure of the spill valve assembly is simple.

Description

technical field [0001] The present application relates to the technical field of manufacturing fuel cell vehicles, in particular to an overflow valve assembly, a hydrogen storage system with the overflow valve assembly, and a fuel cell vehicle with the hydrogen storage system. Background technique [0002] The hydrogen storage system of a fuel cell vehicle should contain a main shut-off valve, a check valve, a pressure regulator, and a restrictor valve. The main shut-off valve is usually an electric solenoid valve whose main function is to shut off the hydrogen supply from the storage tank to the downstream side of the valve body. The check valve is used to prevent the hydrogen storage tank from flowing back into the hydrogen supply pipeline. The restrictor valve is used to cut off the supply of hydrogen in the event of rupture of the hydrogen supply pipeline (referring to the pipeline connecting the hydrogen storage system and the fuel cell system). The valve body can be a...
