Description
The present invention utilizes a kind of multi-level safety that the pressure reduction principle design goes out to store the device of pressurized gas.
The device that stores pressurized gas at present has oxygen cylinder, nitrogen bottle, gas can etc.For these high-pressure gas cylinders have good Security, cylinder wall needs very thick, makes cylinder body very heavy.For safety, these air reservoirs often can not be adorned pressurized gas at full capacity when transportation.Utilize very heavy air reservoir but can not adorn more pressurized gas, make resource fail well to be utilized.People are developing more reliable material and are making the high-pressure gas cylinder, but owing to problems such as welding, cost of material, are difficult to promote the use of.At the problems referred to above, in order to deliver and use pressurized gas safely and efficiently,, adopt the method for high voltage protective layer according to the pressure reduction principle, invent out safety high-pressure multi-layer gas cylinder.
During gas in using the high-pressure gas cylinder, generally do not need very high air pressure, will pass through the reduction valve reduced pressure treatment usually, make air pressure reduce to needed air pressure range.And the gas that air reservoir air pressure loads when low is few, danger close all in transportation and when using when general high-pressure gas cylinder charges into the gas of 30MP air pressure now.In order to make air reservoir can store gas than highpressure, guarantee that again it is reliable and secure, therefore invented the safety high-pressure air reservoir of multi-layer structure.Shown in figure (1), be about three layers of air reservoir, innermost is air reservoir 1; The centre is an air reservoir 2; The outside is an air reservoir 3.
Air reservoir 1 is outer to have the elastic support 12 of material such as rubber can be fixed on the centre of air reservoir 2; Air reservoir 2 outer elastic supports 11 can make air reservoir 2 be fixed on the centre of air reservoir 3.Air reservoir 1 is less with the gap of air reservoir 2, uses as the high voltage protective layer of air reservoir 1.This high voltage protective layer can add one or more layers again, and this just need add one or more air reservoirs, utilizes this method to determine to add which floor high voltage protective layer according to actual needs.Is the theory structure that example illustrates the present invention at this with three layers of air reservoir.
The body of inflating inflate in air reservoir 1 by the high pressure pipe line 8 that communicates with air reservoir 1 through air valve 6.The reduction valve 4 and 5 of unidirectional conducting is housed respectively on the air reservoir 1 and 2.When the gas atmosphere of being filled in the air reservoir 1 reached certain value, the reduction valve 4 of air reservoir 1 was opened and inflates in air reservoir 2; When the air pressure in the air reservoir 2 reached certain value, the reduction valve 5 of air reservoir 2 was opened and inflates in air reservoir 3.The air pressure of gas is detected by barometer 10 in the air reservoir 3, just stops inflation when the air pressure in the barometer 10 detection air reservoirs 3 reaches specified value.This moment, three air reservoirs just were full of the gas of different air pressure.
If reduction valve 4 and 5 is made decompression pressure reduction when all be 15MP, then air reservoir 1 is 15MP just with the draught head of air reservoir 2 stored gases; Air reservoir 2 also is 15MP with the pressure reduction of air reservoir 3.The ability of bearing air pressure that is air reservoir 1 and 2 is greater than 15MP, and the air pressure of the stored gas of air reservoir 1 this moment can reach 30MP.If air reservoir 3 can store the gas of 5MP air pressure, when air reservoir 1 was inflated to 35MP so, the air pressure of air reservoir 2 was 20MP, and the air pressure of air reservoir 3 stored-gas just can reach 5MP.If stored gas is nuisanceless gas,, can on air reservoir 3, adorn the reduction valve 18 of a safety as oxygen, nitrogen etc.If, making reduction valve 18 the decompression difference so greater than 5MP, the air pressure that air reservoir 3 can bear is 5MP.When the air pressure of air reservoir 3 surpasses 5MP, the gas in the air reservoir 3 will release automatically by safety relief valve 18, thereby guarantee the safety of this multilayer air reservoir.
Reduction valve 4,5 and 18 theory structure are shown in figure (2) or (3).Figure (2) is to use piston structure, and valve piston 15, relief spring 16 and sealing gasket 17 are housed in reducing valve body 13.Figure (3) is a chip architecture of the spring, and stiffness spring sheet 19, pillar 20 and sealing gasket 17 are housed in reducing valve body 13.When the gas pressure intensity that charges into reaches certain value, will promote piston 15 or stiffness spring sheet 19 is opened reduction valve, in the air reservoir that gas forces down fill gas.If the area on highpressure and lowpressure gas contact piston 15 or shell fragment 19 two sides is respectively S

Safety when guaranteeing to inflate to the multilayer air reservoir, the throughput of reduction valve 18 is greater than the throughput of reduction valve 5; The throughput of reduction valve 5 is greater than the throughput of reduction valve 4; The throughput of reduction valve 4 is greater than the throughput of air valve 6, when making inflation between the multilayer air reservoir gas communication smooth and easy, fluent situation takes place.
The barometer 7 of detected air pressure is housed on air reservoir 1, when barometer is not more than certain certain value with the pressure reduction that is contained in the barometer 10 on the air reservoir 3, just can guarantees to contain the air reservoir 1 of pressurized gas and 2 safety.Air reservoir 1 and 2 ability during all greater than 15MP of bearing air pressure for example, as long as the pressure difference of barometer 7 and barometer 10 is less than 30MP, air reservoir 1 and 2 just is in a safe condition so.Because the real-time detection air reservoir 1 of barometer 7 and 10 and 3 air pressure are arranged, also detect the pressure reduction of air reservoir 1 and air reservoir 3 simultaneously, thereby guaranteed the safety of multilayer air reservoir.
When reality is used the multi-level safety air reservoir, might break down by barometer.It is motionless that for example barometer 10 is damaged its pointer, still detects the barometer 7 of air reservoir 1 and the difference of barometer 10 and need only less than 30MP, and the multilayer air reservoir just still is in a safe condition.If barometer 7 is damaged, when giving the inflation of multilayer air reservoir, just can be found, therefore just can avoid the generation of accident.Air reservoir 3 is equipped with safety relief valve 18 simultaneously, just loses heart automatically when the air pressure in the air reservoir 3 surpasses specified value.The present invention is that the Security that multi-layer structure becomes the low pressure air reservoir is passed through in the Security of high-pressure gas cylinder, and the reduction valve 18 of safety relief is installed on low pressure air reservoir 3, guarantees transporting safely and using of multilayer air reservoir.
During gas in using the multi-level safety air reservoir, mainly be the gas that stores in the air reservoir 1.Can open the gas that air valve 6 uses in the air reservoir 1 by the high-voltage tube 8 that is communicated with air reservoir 1.After the gas in the air reservoir 1 uses, can open the gas that air valve 9 uses in the air reservoir 3.When the pressure reduction of air reservoir 2 and air reservoir 3 during greater than 15MP, the gas in the air reservoir 2 will fill in the air reservoir 3, and when the air pressure in the final air reservoir 2 was reduced to 15MP, the gas in the air reservoir 2 just no longer flowed out.Air reservoir 2 keeps the gas of 15MP air pressure all the time, and promptly air reservoir 2 has been high voltage protective effects, and the gas in the air reservoir 2 is not used.Therefore for cutting the waste, air reservoir 2 is less with the gap of air reservoir 1, makes the volume of stored-gas in the air reservoir 2 less.The volume of air reservoir 3 is more much bigger than the volume of air reservoir 2, and the high-pressure gas cylinder 2 inside making obtains discharging and buffering when accident occurring, is unlikely to cause danger.After the gas in the air reservoir 1 used, the pressure of the pressurized gas in the air reservoir 2 was inwards, did not externally have any danger.The method of this use multilayer air reservoir gas has been guaranteed the Security of the present invention more.
When making the multilayer air reservoir, at first make air reservoir 1, and welding goes up high-voltage tube 8 and reduction valve 4, around air reservoir 1, install the rubber fixed support, from air reservoir 2 is packed air reservoir 1 at the rear portion of air reservoir 2; The bottom buckle closure of air reservoir 2 is passed high-voltage tube 8 welding seal, load onto reduction valve 5, around air reservoir 2, load onto the fixed support of ebonite, put into the air reservoir 3 from the bottom of air reservoir 3; At last the buckle closure of air reservoir 3 bottoms being passed high-voltage tube 8 welding seals.After three air reservoirs install, barometer 7 and air valve 6 are installed again.After the barometer on the air reservoir 3 10, reduction valve 18, air valve 9 install, just can give the inflation of multilayer air reservoir by air valve 6.When the value of barometer 10 surpassed specified value, reduction valve 18 should have gas to release.No matter whether reduction valve 18 loses heart, and the air pressure difference of barometer 7 and barometer 10 can not can not surpass 30MP at this greater than the value that sets.If surpass 30MP explanation reduction valve 4 or 5 problem is arranged, should stop inflation.Utilize this method to carry out quality testing to this multilayer air reservoir.The multilayer air reservoir of being invented in when inflation owing to the detection of pressure reduction is arranged, the safety when having guaranteed inflation.
This invention can store the gas than highpressure.Owing to utilized the pressure reduction principle, the air pressure that each air reservoir bears is decomposed, and makes very thick that the casing wall of each air reservoir can do, identical the getting final product of material of material therefor and existing oxygen cylinder or nitrogen bottle.The weight of whole multilayer air reservoir is also lighter, and has reliable Security.Because safety relief valve 18 has been installed, this multilayer air reservoir is safer, reliable than existing individual layer air reservoir in transportation and use, therefore has excellent popularization, use value.
