Abstract
The utility model relates to a gas defence device for glass fibre coiled gas cylinders, comprising a gas cylinder, a gas pipe, a pressure gauge and a reducing valve. The gas pipe is respectively connected with a one-way valve tee and a quick inflation tee. The inner liner of the gas cylinder is made of aluminum materials. Glass fiber is wound on the inner liner to form an outer shell. Compared with a steel cylinder in same size, the weight of the device is reduced by two thirds, but the compressive strength of the device is as strong as that of the steel cylinder. The device which is light in weight can quickly supplement gas cylinder with air under the condition that the steel cylinder is not dismounted and can use an externally connecting air source directly.
Description
The utility model belongs to the protection of pernicious gas, is specifically related to a kind of winding glass fibre gas cylinder anti-virus device.
At present, in each hazardous medium environment such as oil, chemical industry, fire-fighting, the used steel cylinder air of gas defence is inhaled and is exhaled device to have some problems, adopt steel to make such as gas cylinder, because the ratio great (about 7,8 gram per centimeters) of steel, so the staff often will carry out work under heavy burden reaches the situation of 6-14 kilogram, and gas cylinder is once inflated and can only be used about 30-60 minute, when inflating again, need unload steel cylinder, time-consuming bothersome.
The purpose of this utility model is to provide a kind of in light weight, the winding glass fibre gas cylinder anti-virus device that can replenish air fast.
The utility model is achieved in that with aluminium makes glass liner, and glass fibre is twined outside it, adorns a check valve threeway and fast inflation threeway on appendix respectively.
With aluminium make glass liner, glass fibre is made shell because the proportion of aluminium and glass fibre is all little, about 2,7 gram per centimeters of aluminium, about 1,8 gram per centimeters of glass fibre, so gas cylinder is in light weight, the steel cylinder of equal specification is light by 2/3rds, and its compression strength is identical with steel cylinder.By check valve threeway and fast inflation threeway, under the situation that does not unload steel cylinder, can replenish the air in the gas cylinder fast and directly use external source of the gas.
Accompanying drawing is this schematic representation of apparatus.
Using method below in conjunction with this device of description of drawings:
The pressure-air of gas cylinder (1) lining after pressure-reducing valve (3) throttling, by appendix (4), soon inflate threeway (5), check valve threeway (8), breathe lung (9) and enter face shield (10).
When needing to replenish the air in the gas cylinder, connect fast aeration joint (6), open pressure-reducing valve (3), gases at high pressure enter gas cylinder (1) through fast inflation threeway (5).
When using external source of the gas, close pressure-reducing valve (3), connect snap joint (7), external source of the gas directly enters through check valve threeway (8) and breathes lung (9), face shield (10).
(2)--Pressure gauge (11)---cylinder liner
(12)---gas cylinder shell
Claims (2)
1, twines glass fibre gas cylinder anti-virus device, form by gas cylinder (1), pressure-reducing valve (3), Pressure gauge (2), appendix (4), breathing lung (9), face shield (10), it is characterized in that being connected to respectively on the appendix (4) a fast inflation threeway (5) and check valve threeway (8).
2, device as claimed in claim 1 is characterized in that the inner bag (11) of gas cylinder (1) is made by aluminium, and glass fibre is wrapped in inner bag and forms shell (12) outward.
