Fig. 2 is a kind of schematic diagram of hydrogen stable-pressure device provided by the utility model.
Embodiment
Preferred embodiment provided by the utility model is illustrated with reference to the accompanying drawings.
Fig. 2, it is a kind of preferred embodiment of hydrogen stable-pressure device provided by the utility model.As shown in Fig. 2 the hydrogen
Stable-pressure device includes hydrogen save set 10, and hydrogen save set 10 is provided with the main pipeline for being used for that hydrogen to be imported to equipment 100
20, it is sequentially provided with main pipeline 20 for controlling hydrogen flows out in hydrogen save set 10 controlling switch 21, for showing hydrogen
The pressure gauge 22 of air pressure in gas save set 10, for the first pressure-reducing valve 23 that Hydrogen Vapor Pressure in main pipeline 20 is adjusted with
And it is provided with for controlling hydrogen to flow into the stop valve 24 of equipment 100, between the first pressure-reducing valve 23 and stop valve 24 and is used to prevent hydrogen
First check valve 25 of gas backflow, when in use, controlling switch 21 and stop valve 24 are opened, and make according to the minimum of equipment 100
Dosage demand, adjust the first pressure-reducing valve 23 so that finally meet equipment by input total flow of the stop valve 24 to equipment 100
100 minimum usage amount demand.
The hydrogen stable-pressure device also includes the compensation pipeline 30 in parallel with the first pressure-reducing valve 23 and the first check valve 25, compensation
Pipeline 30 is provided with the second pressure-reducing valve 31 and the second check valve 32 being used for hydrogen is adjusted in compensation pipeline, and first subtracts
The pressure regulation value of pressure valve 23 is more than the pressure regulation value of the second pressure-reducing valve 31, when the minimum usage amount of equipment needs to be more than the defeated of main pipeline 20
When entering amount, on the premise of the pressure value of the first pressure-reducing valve 23 in keeping main pipeline 20 is constant, the second pressure-reducing valve 31 is opened, now
Pressure value in compensation pipeline 30 is more than the Hydrogen Vapor Pressure passed through after the first check valve 25 in main pipeline 20, the second check valve 32
Open, enough pressure and the compensation gas of flow are provided to main pipeline 20 by compensating pipeline 30, and in the first check valve 25
Under effect, compensation gas will not be back to the first pressure-reducing valve 23, the normal work of equipment 100, meanwhile, the first pressure-reducing valve 23 is delayed
Punching, pressure continue to raise, there is provided enough flows work on.
Significantly, since the pressure regulation value of the first pressure-reducing valve 23 is more than the pressure regulation value of the second pressure-reducing valve 31, equipment 100
When the minimum flow requirement used is less than the flow in main pipeline 20, the pressure value after the first check valve 25 is flowed through in main pipeline 20
More than the pressure value in compensation pipeline 30, the second check valve 32 closes, so when compensate in pipeline 30 second pressure-reducing valve 31 not work
Make, therefore compensating gas in pipeline 30 can not enter in main pipeline 20.
Total reduction valve 26 is additionally provided with the main pipeline, total reduction valve 26 is adjacent with the position of pressure gauge 22, can so mitigate
The pressure of first pressure-reducing valve 23 and the second pressure-reducing valve 31, matched somebody with somebody by total reduction valve 26, the first pressure-reducing valve 23 and the second pressure-reducing valve 31
Close and the hydrogen come out from hydrogen save set 10 is depressurized to meet the needs of equipment 100.
The specifically used process of hydrogen decompressor provided by the utility model is：1）Before use：Controlling switch 21 is closed；
The reading of pressure gauge 22 is zero；First pressure-reducing valve 23 and the reading of the second pressure-reducing valve 31 are zero and keep the original state turned on；Cut-off
Valve 24 remains off.2）During use：Open controlling switch 21；Hydrogen Vapor Pressure table 22 is shown as the inside of hydrogen save set 10
Hydrogen Vapor Pressure；Total reduction valve 26 and the first pressure-reducing valve 23 are adjusted, safety requirements is complied with and produces required pressure；Regulation
Second pressure-reducing valve 31, its pressure value are the Hydrogen Vapor Pressure using equipment 100 in use；Opening conduits stop valve 24, makes
Pressure is full of whole main pipeline 20, is passed into using the inside of equipment 100；The use of equipment 100 has minimum pressure requirement, also, main
Pipeline 20 is required under the premise of safe pressure, forbids artificial raising pressure in use.In the case of secured adjusted pressure, if
The standby 100 minimum flow requirements used, during less than flow in main pipeline 20, only by the first pressure-reducing valve 23, it is possible to full
Sufficient production requirement；Also, the second pressure-reducing valve 31 is in the presence of the second check valve 32, because it adjusts pressure ratio main pipeline 20
Low using pressure value, now, the second pressure-reducing valve 31 does not work.3）When requiring that minimum flow is more than main pipeline 20 using equipment 100
During the hydrogen flowing quantity of offer, the pressure value of now the first pressure-reducing valve 23 regulation does not reach requirement, what in tolerance, supply falls short of demand
In the case of, its pressure value can reduce, when the requirement for being reduced to equipment 100 is, the Hydrogen Vapor Pressure of the inside of the second pressure-reducing valve 31
Value is more than the pressure value in main pipeline 20, and now, the second check valve 32 is opened, and the second pressure-reducing valve 31 is opened, and is carried to main pipeline 20
For enough pressure and the compensation gas of flow, and in the presence of the first check valve 25, compensation gas will not be back to first and subtract
Pressure valve 23, the normal work of equipment 100, meanwhile, the first pressure-reducing valve 23 is buffered, and pressure continues to raise, there is provided enough flows
Work on.
In summary, the technical solution of the utility model can realize above-mentioned purpose of utility model, and this with sufficiently effective
The structure and the principle of work and power of utility model have all sufficiently been verified in embodiment, can reach the effect of expected and mesh
, on the premise of without departing substantially from principle of the present utility model and essence, numerous variations can be made to the embodiment of utility model
Or modification.Therefore, the utility model include all be previously mentioned in patent claim in the range of all replacement contents, it is any
The equivalence changes made in present utility model application the scope of the claims, all within the scope of the claims of category this case application.
