Vehicle-mounted hydrogen supply system pipeline system

Abstract

The invention relates to a vehicle-mounted hydrogen supply system pipeline system. The system comprises a hydrogen filling module, a hydrogen storage module and a hydrogen supply module, the hydrogenfilling module is connected to the hydrogen storage module through a hydrogen pipeline, and the hydrogen storage module is connected to the hydrogen supply module through a hydrogen pipeline. The hydrogen supply module is connected to a fuel cell, and the hydrogen storage module comprises a hydrogen storage bottle and a bottle valve assembly; the bottle valve assembly comprises a bottle valve mounted at a bottle opening of the hydrogen storage bottle, and a first one-way valve, a stop valve and an overflow valve which are integrated on the bottle valve and are sequentially connected in seriesbetween the bottle valve and the bottle opening of the hydrogen storage bottle, and the first one-way valve is connected with an electromagnetic valve in parallel; and the bottle valve is provided with an air inlet and an air outlet, so that a plurality of hydrogen storage bottles are connected in series. Compared with the prior art, the system has the advantages of safety, reliability, simple process, low cost, few leakage points and the like.

Description

technical field [0001] The invention relates to the field of structural optimization of a vehicle-mounted hydrogen supply system, in particular to a pipeline system of a vehicle-mounted hydrogen supply system. Background technique [0002] With the guidance and implementation of a series of new energy policies in the country, hydrogen fuel cell vehicles have entered a stage of rapid development in recent years, and the on-board hydrogen supply system is used as the hydrogen storage and supply system of hydrogen fuel cell vehicles. One of the keys to safe and reliable driving of hydrogen fuel vehicles. Considering that the volume of hydrogen is very small, it is easy to leak, and every connection point of the pipeline on the vehicle-mounted hydrogen supply system, whether it is a ferrule connection or a threaded connection, has a hidden danger of leakage, especially some high-pressure pipelines are limited by the layout environment There may be installation stress. Under the...

Problems solved by technology

However, in this patent, the valve assembly that cooperates with the bottle valve to complete the hydrogen flow control needs to be additionally installed, which increases the connection points, resulting in more possible leaks and increased installation costs; moreover, the two outlets of the bottle valve of the device Only one overflow valve is installed, and the pipeline at the other outlet cannot effectively overflow when the pipeline ruptures under extreme conditions, which has certain potential safety hazards, and the valve parts in the system of this patent technology There are still too many connection points, which is not conducive to reducing costs and further improving the safety of hydrogen systems
