Abstract
The utility model discloses a device for supplying gas by high-pressure gas bottles connected in parallel, which comprises a plurality of high-pressure gas bottles and output pipelines, wherein outlets of the high-pressure gas bottles are provided with decompression gate valves; the device is characterized by further comprising a pressure one way valve of which the input end is connected to the output end of the decompression gate valve and the output end is connected with the output pipelines; and the device for supplying gas by high-pressure gas bottles connected in parallel solves the problem existing n the prior art that the high-pressure gas bottle with high output pressure causes obstruction to the high-pressure gas bottle with low output pressure.
Description
Technical field
The utility model relates to a kind of gas cylinder parallel connection air feeder, and it belongs to resuscitation apparatus air feeder class.
Background technique
In the rescue field, comprise mine rescue and medical aid, the gas cylinder parallel connection is a kind of mode commonly used to the resuscitation apparatus air feed.In the prior art; The most common mode is connected in parallel after for the reduction valve decompression of several gas cylinders through separately, and the problem that existing technology exists is that each gas cylinder can not be in full accord through the post-decompression pressure of reduction valve separately, the higher lower formation to delivery pressure of delivery pressure can take place for this reason hinder; Can influence the gas supply capacity of whole system when serious; Since gas cylinder with reduction valve generally be to dispatch from the factory and just configured the device of Pressure reducing ratio, although the possibility of regulating, from the angle of safety; Do not hope that the client transfers this and cut; So when this situation about occurring, usually also be difficult to solve at the scene, existing technology has further improved necessity for this reason.
Summary of the invention
The purpose of the utility model is to provide a kind of gas cylinder parallel connection air feeder, to overcome the problem that existing technology exists.
A kind of gas cylinder parallel connection air feeder of the utility model; Comprise several gas cylinders, output pipeline; The delivery outlet of said gas cylinder has the decompression gate valve; It is characterized in that also comprising a pressure check valve, the input end of said pressure check valve is connected to the output terminal of decompression gate valve, and output terminal is connected to output pipeline.
This gas cylinder parallel connection air feeder of the utility model; Because the output terminal at the decompression gate valve has inserted pressure check valve, said pressure check valve is because its working principle has determined it that certain damping function is arranged, and the gas of exporting through pressure check valve all has pressure decay to a certain degree; For this reason; Gas pressure in the output pipeline always can be lower than decompression gate valve output terminal one one magnitude, for this reason, even the air pressure of each gas cylinder after the output of decompression gate valve is different; Also ten minutes is limited to the influence of other gas cylinder output owing to the difference of pressure behind output pipeline, thereby the utility model has solved the problem that existing technology exists.
As further improvement, also be connected to a bypass pressure release gate valve on the pipeline of said pressure check valve and decompression intervalve, the benefit that is provided with like this is; Because after having increased pressure check valve, the pressure of said pressure check valve and decompression intervalve can be bigger, this pressure also can exist after gas cylinder gas has supplied; Can impact the connecting tube of dismounting with the decompression gate valve; Through a bypass Decompression valves is set, can release this pressure, to make things convenient for the replacing of gas cylinder.
As further improving; Be connected in the output of high-pressure manometer, reduction valve pressure pressure table in pressure pressure table and the pipeline on the input end of said decompression gate valve, output terminal and the output pipeline respectively, the benefit of setting is to be convenient to the working state that the staff grasps the air feeder of the utility model comprehensively like this.
Description of drawings
Fig. 1 is a kind of gas cylinder parallel connection air feeder structural representation that the utility model preferred embodiment provides.
Among the figure, 1 be gas cylinder, 2 for the decompression gate valve, 3 for high-pressure manometer, 4 for bypass pressure release gate valve, 5 for pressure pressure table in the reduction valve output, 6 for pressure check valve, 7 for pressure pressure table in the pipeline, 8 for output pipeline, 9 be resuscitation apparatus.
Embodiment
A kind of gas cylinder parallel connection air feeder and the accompanying drawing thereof that below will combine the utility model preferred embodiment to provide are described further the utility model.
A kind of gas cylinder parallel connection air feeder that the utility model preferred embodiment provides; Shown in accompanying drawing 1; Comprise several gas cylinders 1, output pipeline 8, the delivery outlet of said gas cylinder 1 has decompression gate valve 2, and its main points are also to comprise a pressure check valve 6; The input end of said pressure check valve 6 is connected to the output terminal of decompression gate valve 2, and output terminal is connected to output pipeline 8.
In this preferred embodiment; Also be connected to a bypass pressure release gate valve 4 on the pipeline that said pressure check valve 6 and decompression gate valve are 2; Simultaneously, be connected in the output of high-pressure manometer 3, reduction valve pressure pressure table 7 in pressure pressure table 5 and the pipeline on the input end of said decompression gate valve 2 and output terminal and the output pipeline 8 respectively, in this preferred embodiment; Gas in the said gas cylinder 1 outputs to output pipeline 8 through decompression gate valve 2 and pressure check valve 6, again by output pipeline 8 to resuscitation apparatus 9 air feed.
In sum; A kind of gas cylinder parallel connection air feeder of the utility model comprises several gas cylinders, output pipeline, and the delivery outlet of said gas cylinder has the decompression gate valve; It is characterized in that also comprising a pressure check valve; The input end of said pressure check valve is connected to the output terminal of decompression gate valve, and output terminal is connected to output pipeline, and the utility model has solved the higher problem that lower formation hinders to delivery pressure of gas cylinder delivery pressure that existing technology exists.
The above is merely the embodiment of the utility model.But the utility model protection domain is not limited thereto.Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses; The variation that can expect easily or replacement; All should be encompassed within the protection domain of the utility model, therefore, the protection domain of the utility model should be as the criterion with the protection domain of claim.
