Energy problem is one of the major issue that today's society faces, and the energy of fossil fuel is exhausted at last.So exploitation
The new energy is the trend that today's society is pursued, and one kind that the fuel cell of no pollution to the environment is new energy development becomes
Gesture.Fuel cell is (vapour, diesel oil) or energy storage (battery) mode -- the most allusion quotation rather than use is burnt by electrochemical reaction
Traditional backup power supply scheme of type.Burning can be discharged as pollutants such as COx, NOx, SOx gas and dust.As described above, fuel
Battery can only generate water and heat.If hydrogen is to generate (photovoltaic battery panel, wind power generation etc.) by renewable energy, entirely follow
Ring is exactly the process for not generating discharge of poisonous waste thoroughly.Hydrogen belongs to low molecular weight gas, and explosion limit range is: 4.1%
~74.2% volumetric concentration, easily explodes, and causes safety accident, and 35MPa and 70MPa two are divided in 1 market of mesh front-end hydrogenation rifle
A pressure rating, be primarily present following technical problem: mode of operation is mostly two-handed hand-held type, is unfavorable for aerating personnel progress
Filling operation；Add hydrogen mouth 23 to vehicle fueling hydrogen by hydrogen cell automobile side simultaneously, belongs to hyperbar, it is explosion-proof
Demanding operating condition adds in hydrogen rifle 1 and high-pressure hose and is chronically at high pressure conditions, be easy to cause the safety accidents such as booster；And
Since pressure is higher higher to leakproofness and security requirement in gun body and high-pressure hose, meet in compressive resistance also needs completely simultaneously
Sufficient zero leakage air-tightness requirement, sealing material need to be provided simultaneously with self-lubricating, macromolecule tissue；Meanwhile existing hydrogenation plant,
Add hydrogen rifle 1 the device is complicated that degree is high, handle is cumbersome, be not suitable for quickly, frequent installation, disassembly use demand, simultaneously
Lack perfect self-locking device, safety is to be improved, and technical solution is unfolded as follows the present invention is based on this.
Fig. 1 is the structural schematic diagram of internal pressure balance of the present invention plus hydrogen rifle 1, and as can be seen from Figure 1 plus hydrogen rifle 1 is hand-held
Hydrogenation plant adds setting is once connected in hydrogen rifle 1 first chamber 2, second chamber 3 and third chamber 4, further include hand rest with
And trigger 14, inlet channel 11 and exhaust passage 12 are provided in hand rest, and inlet channel 11 is connected to first chamber 2, and exhaust is logical
Road 12 is connected to second chamber 3, and inlet channel 11 further includes a branch pipe 1101, and hydrogen fuel is introduced the first spool by branch pipe 1101
5 and first between valve seat 6, and hydrogen fuel pushes the first spool 5 mobile to the direction far from the first valve seat 6, and then realizes the first chamber
The sealing of room 2 and second chamber 3, in this way setting avoid hydrogen-storing device and take place frequently starting and the problem of close, it is only necessary to by hand-held
Formula equipment can realize plus the starting and closing of hydrogen rifle 1, and trigger 14 drives needle-valve 13 and vent valve 21, needle-valve 13 being capable of connected component
Pipe 1101 and exhaust passage 12, and branch pipe 1101 and inlet channel 11 are closed, the hydrogen combustion in the first spool 5 and the first valve seat 6
Material is back in hydrogen-storing device by the exhaust passage 12 that needle-valve 13 is connected to, and the motive force of the first spool 5 weakens, and hydrogen fuel passes through
Inlet channel 11 enters first chamber 2, and the direction for pushing the first spool 5 to close first valve seat 6 is mobile, and then is connected to first
Chamber 2 and second chamber 3, hydrogen fuel enter in second chamber 3, but due to the configuration relation of the second spool 8 and the second valve seat 9,
Add hydrogen rifle 1 not with when hydrogenation plant 22 plus hydrogen mouth 23 cooperate when, hydrogen fuel can only be stored in second chamber 3, in this way
Setting avoid due to make mistakes cocking 14, and then cause hydrogen fuel reveal bring security risk, when add hydrogen rifle 1 with plus hydrogen
When mouth 23 cooperates, add hydrogen mouth 23 that the second spool 8 is pushed to slide in second chamber 3 and third chamber 4, and then is connected to second chamber
3 and third chamber 4, cocking 14 at this time, hydrogen fuel repeat it is above-mentioned enter first chamber 2 from inlet channel 11, it is rear to enter again
The process of second chamber 3 enters third chamber 4 by second chamber 3, eventually by adding hydrogen mouth 23 to enter to hydrogenation plant 22,
From Fig. 1 it can also be seen that adding the front end of hydrogen rifle 1 to be provided with locking device 15, the ball 19 of locking device 15 and plus hydrogen mouth 23
The card slot 24 in outside cooperates, and in the case where the hydrogen fuel in third chamber 4 pushes, realization is self-locking, avoids in the mistake for adding hydrogen operation
Cheng Zhong, security risk caused by adding hydrogen rifle 1 to fall off suddenly.
Fig. 2 is the portion the A enlarged diagram of internal pressure of the present invention balance plus hydrogen rifle 1, the structure of main presentation locking device 15, from
It can be seen that the internal structure, including locking sleeve 16, outlet valve seat, locking spring, ball 19 etc. of locking device 15 in Fig. 2,
