The utility model makes the gas-storing capacity of resuscitation apparatus increase by the quantity that increases gas cylinder, makes and can increase for the pressurized gas that consumes, and has increased the service time of resuscitation apparatus from the gas-storing capacity aspect; Beginning discharging and stopping discharging by pressurized gas in the stop valve control gas cylinder, make resuscitation apparatus when not needing to discharge, can block the discharging of pressurized gas in the gas cylinder by stop valve, thereby pressurized air can be fully utilized, reduce the unnecessary loss of pressurized gas; To discharge after the pressurized gas step-down in the gas cylinder by reduction valve, the compression pressure of storage in the gas cylinder can suitably be increased, the gas that is storage in the single gas cylinder can increase in right amount, improved the gas-storing capacity of pressurized gas in the single gas cylinder, therefore the utility model has improved the life cycle of resuscitation apparatus from the gas-storing capacity of single gas cylinder, total gas-storing capacity and pressurized gas utilization efficiency three aspects, prolong service time, solved resuscitation apparatus short problem service time in the prior art.
Description of drawings
Fig. 1 is embodiment's of the present utility model structural representation.
Embodiment
The embodiment of respiratory gas source device of the present utility model: as shown in Figure 1, this respiratory gas source device comprises link press span 9, the switching piece 2 of bridge joint between the bottleneck of two gas cylinders 8 of two gas cylinders 8, fixedly connected two gas cylinders 8, gas charging valve 1, reduction valve 4, stop valve 7, pressure gauge 6, safety valve 5, the out splice going splice 3 of installing on the switching piece 2.Two gas cylinders 8 are fixed together by link press span 9.Switching offer on the piece 2 with the bottleneck of two gas cylinders 8 one by one gas-entered passageway, two gas-entered passageways of connection of corresponding connections main airway, respectively at outlet passageway and the filling channel of main airway connection, be equiped with gas charging valve, outlet connection in the import of filling channel on main airway, be equiped with out splice going splice 3 in the outlet of outlet passageway, import is communicated with on main airway, and stop valve 7, pressure gauge 6, reduction valve 4, safety valve 5 and out splice going splice 3 are communicated with on outlet passageway, and distribute successively downstream from the upstream along the gas flow direction.
Present embodiment fills into pressure in the gas cylinder 8 for the pure oxygen after compressing by gas charging valve 1 in use, and pressure gauge 6 can be monitored a bottle internal air pressure in real time.In needs use bottle during gas, open stop valve 7, gas enters the gas-entered passageway of switching on the piece 2 by bottleneck in the bottle, and enters outlet passageway through stop valve 7 water conservancy diversion, and the pressure gauge 6 of flowing through successively in outlet passageway, reduction valve 4, safety valve 5 are discharged from out splice going splice 3.
Present embodiment is applicable to that the space flight personnel use in movement process, so the weight of product is strict, gas cylinder 8 materials adopt the high strength stainless steel material, the tensile strength of this material can be up to more than the 1300MPa, can reduce wall thickness as far as possible like this, reach the purpose that alleviates product weight, the bearing capacity of product can be higher than 18MPa.Switching piece 2 adopts the duralumin material, when satisfying intensity, piece 2 weight reduce to transfer as far as possible, and gas charging valve 1, pressure gauge 6, stop valve 7, reduction valve 4 and safety valve 5 are integrated, the auxiliary hole design is ingenious, not only alleviated the gross weight of product greatly, and easy to carry, simple to operate.The use of two gas cylinders 8 increases the disposable gas-storing capacity that carries of wearer and is twice, and has prolonged service time; The use of precision pressure gauge 6 can be monitored the variation of pressure in the gas cylinder 8 constantly, accurately reflects the residual capacity of gas; The handle of stop valve 7 adopts the decompression handle of plum blossom shape, and the handle of stop valve 7 adopts discoid Joystick, and with difference stop valve 7 and reduction valve 4 structures, being conducive to the user opens stop valve 7 in flurried switch is own oxygen supply; Reduction valve 4 can be guaranteed gas pressure and the stability of flow of discharge from out splice going splice 3, it is little to fluctuate, and the end at switching piece 2 has increased safety valve 5, surpass to a certain degree releasing pressure automatically at pressure, thereby prevention pressure surpasses the danger that to a certain degree causes, and uses safer, therefore present embodiment is used oxygen for the space flight personnel provide to breathe, it is narrow-minded to solve traditional resuscitation apparatus, and weight is big, the problem of instability of flow.
