The utility model has the advantages of simple structure, safe use, safe operation, convenient use and convenient operation, the hydrogen store device replacing can be realized under the condition of the uninterrupted duty of the fuel cells, and the long-playing uninterrupted power supply of the fuel cells can be effectively ensured.
Description
One, technical field
The utility model relates to a kind of hydrogen supply device of fuel cell generation, and particularly a kind of fuel cell is with the uninterrupted hydrogen supply device of two-way.
Two, background technology
Fuel cell is a kind of novel generating equipment, and its fuel is hydrogen, must provide hydrogen for it incessantly when therefore working.At present, the used storage hydrogen device (jar) of fuel cell through gas switch, gas conduit, pressure-reducing valve, pressure regulating valve to fuel cell hydrogen-feeding, what adopt all is opening method of supplying, promptly put hydrogen till being unable to supply since a tank storage hydrogen device, the heart must stop the work of fuel cell earlier after it has put hydrogen, store up the replacing of hydrogen device (jar), behind the good new storage hydrogen device (jar) to be replaced, could again the fuel cell start be worked on.This mode need stop operation of fuel cells earlier when changing storage hydrogen device, can't guarantee the long-time uninterrupted power supply of fuel cell.
Three, summary of the invention
The purpose of this utility model is intended to overcome the deficiencies in the prior art, provide a kind of simple in structure, use and put just, under the condition that does not stop operation of fuel cells, online transposing storage hydrogen device (jar), the fuel cell of the long-time uninterrupted power supply of realization fuel cell is with the uninterrupted hydrogen supply device of two-way.
The utility model adopts such technical scheme: a kind of fuel cell is with the uninterrupted hydrogen supply device of two-way, include gas conduit, pressure-reducing valve, pressure regulating valve, gas switch, it is characterized in that also being provided with a tee pipe coupling, the delivery outlet of tee pipe coupling is connected with the entrance point of pressure-reducing valve, two entrance points of tee pipe coupling are connected with a gas conduit respectively, the other end of two gas conduits is connected with the port of export of the unidirectional valve of band snap joint seat, the inlet union seat end of the unidirectional valve of band snap joint seat can be pegged graft with the plug end of quick plug, the other end of quick plug is connected with an end of gas switch, and the other end of gas switch is connected with the hydrogen opening of peripheral hardware storage hydrogen device.
The fuel cell that the utility model provides is with the uninterrupted hydrogen supply device of two-way, because the entrance point at pressure-reducing valve is provided with tee pipe coupling, make this device have two and send the hydrogen path, thereby can or provide hydrogen to fuel cell separately from the two-way while, every unidirectional valve that send hydrogen pipeline all to include band snap joint seat respectively, quick plug and gas switch, guarantee that institute's hydrogen supply gas can only one-way flow, two are sent hydrogen pipeline to converge into one after tee pipe coupling, by pressure-reducing valve, after dropping to Hydrogen Vapor Pressure in the fuel cell pack normal range of operation, pressure regulating valve enters the air inlet of fuel cell pack.When using one to send the hydrogen pipeline hydrogen supply, the pipeline of quick plug and gas switch is connected with storage hydrogen device, again quick plug is inserted in the unidirectional valve of band snap joint seat, open gas switch, this moment, fuel cell pack was started working, because another send the existence of hydrogen pipeline unidirectional valve, quick plug does not insert unidirectional valve, so in single channel hydrogen supply process hydrogen not can from another not the hydrogen mouth that advances of usefulness leak, and can only be after pressure-reducing valve, pressure regulating valve decompression, directly to enter fuel cell pack.During replacing, new storage hydrogen device is connected on the untapped hydrogen supply pipeline, pegged graft quick plug and unidirectional valve, open gas switch, this moment, fuel cell pack was in two sources of the gas state of hydrogen supply simultaneously, and then the gas switch of the storage hydrogen device that has supplied hydrogen before turn-offing, pull out quick plug, remove the storage hydrogen device that runs out of, finish the replacing of source of the gas, can take turns repeatable operation with this, the storage hydrogen device that is implemented under the uninterrupted condition of operation of fuel cells is changed, effectively guaranteed the long-time uninterrupted power supply of fuel cell, it is simple in structure, uses easy-to-operate.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: the unidirectional valve 4-tee pipe coupling 5-gas conduit 6-pressure-reducing valve 7-pressure regulating valve of 1-gas switch 2-quick plug 3-band snap joint seat
Five, embodiment
Embodiment of the present utility model is described with reference to the accompanying drawings.As shown in drawings, a kind of fuel cell is with the uninterrupted hydrogen supply device of two-way, include gas conduit 5, pressure-reducing valve 6, pressure regulating valve 7, gas switch 1, also be provided with a tee pipe coupling 4, the delivery outlet of tee pipe coupling 4 is connected with the entrance point of pressure-reducing valve 6, two entrance points of tee pipe coupling 4 are connected with a gas conduit 5 respectively, the other end of two gas conduits 5 is connected with the port of export of the unidirectional valve 3 of band snap joint seat, the inlet union seat end of the unidirectional valve 3 of band snap joint seat can be pegged graft with the plug end of quick plug 2, the other end of quick plug is connected with an end of gas switch 1, and the other end of gas switch 1 is connected with the hydrogen opening of peripheral hardware storage hydrogen device.The unidirectional valve of band snap joint seat and quick plug adopt single enclosed hydraulic quick coupler 9123 spigot joint bodies and the 9085 intubate plug body that the method national music can sharp company (Legris).When not inserting quick plug in the snap joint seat of unidirectional valve, this moment, unidirectional valve was in the unidirectional blocking state; When inserting quick plug in the snap joint seat of unidirectional valve, this moment, unidirectional valve was in flowing gas state.
