Accompanying drawing explanation
Fig. 1 is principle of the invention block diagram.
Detailed description of the invention
Below according to accompanying drawing and in conjunction with the embodiments, the invention will be further described.
Fuel cell shown in Fig. 1 can supply convergence system by filling type, and this system is by the gas filling unit being sequentially connected with
1, gas cylinder confluxes switch unit 2 and safe unit 3 collectively constitutes.It is anterior that described gas filling unit 1 is positioned at system, is outside connection
The interface end of portion's hydrogen make-up.Gas filling unit 1 is two-way pipeline side by side configuration, and often after route forward direction, series winding connects external successively
Mouth 1.1, ball valve 1.2 and stop valve 1.3.Ball valve 1.2 in two-way pipeline and between stop valve 1.3 by pipeline 1.4 structure in parallel
Becoming valve-regulated intercommunication loop, had this loop to be easy to do following several hydrogen make operating mode, the first operating mode is that a road is open-minded, separately
One tunnel is closed；The second operating mode is that a road stop valve 1.3 is closed, and formation cross aisle opened by another road stop valve 1.3；The third
Operating mode is that two-way pipeline together opens or closes.The described gas cylinder switch unit 2 that confluxes is two-way pipeline side by side configuration equally, this reality
The hydrogen valve 2.1 that Shi Lizhongmei road 3 series windings of configuration connect, every hydrogen valve 2.1 connects hydrogen cylinder 2.3 by corrugated tube 2.2.Two
The preposition hydrogen valve 2.1 in road jointly docks gas filling unit 1 and constitutes valve-regulated hydrogen make passage, and two-way is in the hydrogen of position, end
Air valve 2.1 connects distributing valve 2.5 two ends, the unified high pressure hydrogen being concentrated output pressure to be 15MPa by distributing valve 2.5 respectively.Institute
Stating safe unit 3 actually decompressing unit, it is positioned at gas cylinder and confluxes after switch unit 2.Safe unit 3 is by preposition filter
3.1 introduce high pressure hydrogen, in high pressure hydrogen the order latter linked air relief valve 3.2 of entrance, electromagnetic valve 3.7 from distributing valve 2.5
Being depressurized output, this low pressure hydrogen output channel is used for the fuel cell that outer connection is supporting, and the present embodiment fuel cell uses
Hydrogen Vapor Pressure is 0.8MPa.In order to prevent air relief valve 3.2 to lose efficacy or pipeline flush excretion time system uses first, at air relief valve
Between 3.2 with electromagnetic valve 3.7 respectively connection safety valve 3.4, bypass valve 3.5 constitute together with drain passage, outer drain passage export
End is configured with spark arrester 3.6, and its purpose guarantees to drain the safety of hydrogen.Can fill for the ease of intelligent management fuel cell
Formula supply convergence system, in systems pressure sensor on two positions, primary importance is that distributing valve 2.5 two ends are respectively arranged
One pressure rating is the high-pressure pressure sensor 2.4 of 16MPa, and the second position is that electromagnetic valve 3.7 front end is provided with pressure rating and is
The low-pressure sensor 3.3 of 1MPa, sends hydrogenation information and safety information to electric control gear or work people in time by monitoring
Member.Present invention hydrogenation has two channels to use, and first hydrogenation channel is the hydrogen cylinder that changes the outfit, and the second channel passes through gas filling list
External tapping 1.1 in unit 1 docks with external hydrogen tank car.
The present invention is confluxed switch unit 2 by gas filling unit 1, gas cylinder and safe unit 3 collectively constitutes, for the ease of pipe
Reason and regulation, these three part is jointly concentrated and is placed in same frame, in addition to supporting corrugated tube 2.2 and hydrogen cylinder 2.3, remaining
Each parts are all concentrated and are placed in cabinet wall same panel.
In the present invention, the hydrogen cylinder 2.3 of configuration is detachable, and this kind structure that breaks the whole up into parts is easy in the case of without lifting appliance
Install, also allow for regular maintenance and management.The most important thing is that the present invention uses two-way pipeline alternately supply, a pipeline of bye
It is easy to change the outfit hydrogen cylinder or scene fills hydrogen, owing to having accomplished timely hydrogen make-up, fuel cell uninterrupted power supply can be realized.
