Description
Technical field
The utility model belongs to fuel cell hydrogen supply technical field.
Background technique
Chinese patent CN101454736A discloses a kind of pressure-control valve suitable for fuel cell, have leakproofness and
Durability.Moving portion using marmem as temperature feedback, plays cut-off；Movable part is controlled by pressure difference, every
Film is as pressure difference induction mechanism.
Chinese patent CN206708472U discloses a kind of high pressure hydrogen pressure reducing valve, mainly solves to exist in the prior art
The problem of reaching fuel cell pressure, is difficult to the decompression of the level-one of hydrogen-storing device.
Chinese patent CN103245139A discloses a kind of combination valve using pilot valve, takes into account the control essence of small flow
The demand of degree and big flow improves leakproofness and reliability.
Chinese patent CN206003892U discloses a kind of combination valve and integrates shut-off valve, pressure reducing valve and pressure sensor, answers
For fuel cell unmanned plane or emergency power supply, gas storage system is connected, high pressure admission is belonged to.
Currently, fuel cell hydrogen supply from gas storage system come out after, successively pass through back-fire relief, filtering, mechanical second level
Pressure reducing valve, shut-off valve etc., subsequently into spraying system, using discrete component, structure is complicated, and component is more, and interface is more, causes to pacify
Full performance decline.The mechanical pressure reducing valve used cannot achieve and adjust control in real time.
Summary of the invention
To solve the above-mentioned problems, the utility model provides a kind of fuel cell pressure adjustment module, it includes decompression
Valve 6, the fire arrester 1 with filtering, module body 5, shut-off valve 3, safety valve 7 and the connector 2 for connecting pressure sensor.
It is equipped with cavity, air inlet and air outlet in the module body 5, the cavity is communicated with air inlet, at air inlet

Pressure reducing valve 6 is communicated with safety valve 7, and the pressure reducing valve 6 is communicated with gas outlet, and the air inlet and air outlet are respectively equipped with pressure
Force snesor connector 2 is for connecting pressure sensor.
The utility model has the beneficial effects that
Compact-sized, safety is good, response quickly, is applicable in different flow, power demand.
Detailed description of the invention
Fig. 1 fuel cell low pressure adjusts modular structure schematic diagram；
Fig. 2 fuel cell low pressure adjustment module cross-sectional view.
Mark it is as follows: 1- with filter fire arrester, 2- sensor interface, 3- shut-off valve, 5- module body, 6- pressure reducing valve,
7- safety valve.
Specific embodiment
Illustrate the embodiment of technical solution of the present invention in conjunction with Fig. 1,2.
A kind of fuel cell pressure adjustment module, it includes pressure reducing valve 6, the fire arrester 1 with filtering, module body 5, cut-off
Valve 3, safety valve 7 and the connector 2 for connecting pressure sensor.
It is equipped with cavity, air inlet and air outlet in the module body 5, is equipped at the air inlet of the cavity with filtering
Fire arrester 1, the top of the cavity are equipped with shut-off valve 3, and the lower section of the cavity is equipped with pressure reducing valve 6, the pressure reducing valve 6 and safety
Valve 7 communicates, and the pressure reducing valve 6 is communicated with gas outlet, and the cavity is equipped with the pressure sensor connector 2.
Fire arrester 1, pressure reducing valve 6, shut-off valve 3, safety valve 7 etc. are integrated on a valve body, hydrogen supply had both been able to satisfy
Functional requirement, and security reliability can be improved, control is flexible.
The filtering of the set of fire arrester 1, check (non-return) valve and the back-fire relief pipe of the band filtering, reduce the separately installed of filter, prevent
Safety is reinforced in tempering.
The pressure reducing valve 6 adjusts pressure characteristic according to the pressure demand of system using Electromagnetic Control in real time.Pressure reducing valve 6 with
Safety valve 7 combines, and when pressure reducing valve 6 breaks down, air pressure inside is increased, and is more than the opening of safety valve 7 after certain pressure value, plays protection
Effect.
The shut-off valve 3 maintains a normally open, when fuel cell or air system failure, coil blackout driving cut-off
Valve is closed, it is ensured that the leakproofness of high pressure.
Fuel is provided by fuel cell gas storage system, and the fuel after level-one depressurizes enters institute of the present invention by air inlet
Pressure adjusting module is stated, the fire arrester 1 by band filtering filters, and shut-off valve 3 is normally opened, and hydrogen enters pressure reducing valve 6 and is decompressed to
Required gas pressure subsequently enters spraying system by being exported to module gas outlet.
Gas pressure and gas after decompression before the pressure sensor test that the pressure sensor connector 2 is separately connected is depressurized
Body pressure.The pressure sensor connects a microprocessor system, passes through the intracorporal pressure value of pressure sensor test chamber.
