Abstract
The utility model discloses an oxygen supplying structure of a plateau railway passenger car, which comprises an oxygen generating device and an oxygen outputting and controlling device used for generating oxygen, controlling and operating the outputting density and the outputting flow of the oxygen, and protecting equipment, wherein, the oxygen outputting and controlling device comprises an oxygen outputting pipe and a controlling valve; the oxygen outputting pipe is connected with an outputting pipe of an air conditioning system, to integrate oxygen supplying and air conditioning into a whole. The oxygen supplying structure has the advantages that the structure is simple, and because the utility model is organically combined with the prior air conditioning system of plateau railway passenger cars, the oxygen supplying structure is more practical and is suitable for the plateau railway passenger cars.
Description
Technical field
The utility model relates to a kind of oxygen supply structure, especially uses the oxygen supply structure on the plateau railway passenger vehicle.
Background technology
Qinghai-Tibet Railway is the highest and the longest plateau railway of circuit of height above sea level in the world.The location of height above sea level above 4000 meters has more than 900 kilometer.Du Te plateau geographical environment has determined its airborne oxygen content only to be equivalent to about 50% of oxygen content in the air of sea level like this.Because relative anoxic, passenger and the crew member who takes railway transport of passengers train on the Qinghai-Tibet Railway line generally can uncomfortable in chestly breathe hard, dizzy headache, weakness of limbs, lie awake all night; The heavy meeting of altitude sickness causes encephaledema and pulmonary edema.Therefore, need provide long-time and special quality oxygenation service to the plateau railway passenger.
Chinese patent CN2597285 number disclosed " passenger train oxygen-increasing device " patent (application number: 03202013.9), form by oxygen recurring structure, oxygen supply structure and oxygen transmission structure; The oxygen recurring structure comprises oxygen delivery orifice, oxygen generating plant, oxygen output-controlling device and operation protection chamber, and the oxygen supply structure comprises oxygen input hole, individual oxygen supply conduit and oxygen supply compartment, and the oxygen transmission structure comprises transmitting catheter.The weak point of this patent is: oxygen-increasing device fails to combine with the existing a/c system of plateau railway passenger vehicle, and some repetition therefore seems.
Summary of the invention
The purpose of this utility model is exactly the oxygen supply structure that a kind of plateau railway passenger vehicle simple in structure will be provided, and combines with the existing a/c system of plateau railway passenger vehicle, makes it more practical.
In order to achieve the above object, the oxygen supply structure of the plateau railway passenger vehicle that the utility model provides comprises oxygen generating plant, oxygen output-controlling device, be used to take place oxygen, carry out the output concentration of oxygen and control, operation and the equipment protection of delivery rate, wherein, the oxygen output-controlling device comprises oxygen output tube and control cock; Oxygen output tube is connected with the delivery pipe of a/c system, makes oxygen supply with air regulation and unites two into one.When the utility model used, the oxygen that oxygen generating plant produces entered air conditioner ventilating system through oxygen output tube, and passenger train respectively saved the compartment oxygen supply.
The oxygen supply structure of the plateau railway passenger vehicle that the utility model provides has positive effect: oxygen output tube is connected with the delivery pipe of a/c system, making oxygen supply with air regulation unites two into one, simple in structure, combine with the existing a/c system of plateau railway passenger vehicle, therefore more practical.
Description of drawings
The utility model will be further described in conjunction with the accompanying drawings, please referring to accompanying drawing:
Accompanying drawing 1 expression scheme drawing of the present utility model.
Structure shown in the accompanying drawing 1 comprises: oxygen generating plant 1, control cock 2, oxygen output tube 3, the delivery pipe 4 of a/c system.
The specific embodiment
The oxygen supply structure of the plateau railway passenger vehicle that the utility model provides comprises oxygen generating plant 1, oxygen output-controlling device, be used to take place oxygen, carry out the output concentration of oxygen and control, operation and the equipment protection of delivery rate, wherein, the oxygen output-controlling device comprises oxygen output tube 3 and control cock 2; Oxygen output tube 3 is connected with the delivery pipe 4 of a/c system, makes oxygen supply with air regulation and unites two into one.When the utility model used, the oxygen that oxygen generating plant 1 produces entered air conditioner ventilating system through oxygen output tube 3, and passenger train respectively saved the compartment oxygen supply.
The utility model protection domain relates to all changes form recited above.
Claims (1)
