Abstract
The utility model provides an oxygen flow equalizing pipe, the oxygen flow equalizing flow tube a hollow pipe which is characterized in that one end is opened and the other end is closed, a pore is opened on the pipe wall, the pore diameter from the opened end to the closed end on the oxygen flow equalizing pipe wall is gradually increased, or the pore distribution density from the opened end to the closed end on the oxygen flow equalizing pipe wall is gradually increased, The oxygen can be released to a living cabin through the pore of the oxygen flow equalizing pipe, so that the oxygen in the living cabin is more uniform. The oxygen flow equalizing pipe has the advantages of simple structure, easy manufacture, low cost and convenient usage.
Description
Technical field
The utility model belongs to lifesaving appliance manufacturing technology field, relates to a kind of airtight survival capsule charger, is a kind of oxygen current-sharing pipe specifically.
Background technology
The mining mobile survival capsule is an airtight relatively space, and after catastrophe took place in the down-hole, in time the gug escape personnel got in the survival capsule, utilized the facility that is equipped with in the survival capsule, and assurance hedging personnel's living needs waits for rescue or implement to save oneself.Oxygen supply mode in the survival capsule is generally presses wind oxygen supply and two kinds of forms of compressed gas cylinder oxygen supply, and these two kinds of oxygen supply modes generally adopt the interface of an access survival capsule accommodation when oxygen supply, oxygen is discharged in the accommodation.Find that through test the mode of this oxygen supply can cause the oxygen skewness in the cabin, the concentration of oxygen that different positions records differs bigger, can not satisfy all hedging personnel's in the cabin living necessities.
Summary of the invention
The problems referred to above that the utility model exists to prior art; A kind of oxygen current-sharing pipe is provided; This current-sharing pipe is placed in the survival capsule, survival capsule is carried out oxygen supply, can solve survival capsule oxygen problem pockety through this current-sharing pipe; And simple in structure, be prone to make, cost is low, easy to use.
The purpose of the utility model realizes through following technical scheme:
A kind of oxygen current-sharing pipe is characterized in that: the hollow pipeline of described oxygen current-sharing Guan Weiyi end opening other end sealing has pore on the tube wall.
A kind of improvement to technique scheme: the air vent aperture on the described oxygen current-sharing tube wall from the openend to the blind end increases gradually.
Another kind to technique scheme improves: the gas cell distribution density on the described oxygen current-sharing tube wall from the openend to the blind end increases gradually.
Further improvement to technique scheme: described oxygen current-sharing pipe is linear, L shaped or arc hollow pipeline.
Further improvement to technique scheme: described oxygen current-sharing pipe is the integrative-structure that stainless steel or plastics are processed.
The advantage and the good effect of the utility model are:
The utility model principle is simple, and is easy to use, safe and effective, oxygen problem pockety in the cabin when having solved in the past to the survival capsule oxygen supply.And material is easy to get, and cost is low.
Description of drawings
Fig. 1 is the part section front view of a kind of oxygen current-sharing of the utility model pipe embodiment 1;
Fig. 2 is the part section front view of a kind of oxygen current-sharing of the utility model pipe embodiment 2.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Referring to Fig. 1, the embodiment 1 of a kind of oxygen current-sharing of the utility model pipe, oxygen current-sharing Guan Weiyi end opening 1, the other end have some pores 3 by the hollow pipeline 2 that plug 4 seals on hollow pipeline 2 tube walls.Because no matter adopting the oxygen supply of pressure wind still is that compressed gas cylinder is to the survival capsule oxygen supply; The gas pressure of air inlet port end is usually greater than the gas pressure of end; Therefore; Hollow pipeline 2 is leaning on the pore 3 on the near more tube wall of opening 1 into more little, and is big more from the pore 3 that advances on opening 1 tube wall far away more, can make in the survival capsule oxygen more even like this.
The embodiment 2 of a kind of oxygen current-sharing of the utility model pipe, oxygen current-sharing Guan Weiyi end opening 1, the other end have some pores 3 by the hollow pipeline 2 that plug 4 seals on hollow pipeline 2 tube walls.Because no matter adopting the oxygen supply of pressure wind still is that compressed gas cylinder is to the survival capsule oxygen supply; The gas pressure of air inlet port end is usually greater than the gas pressure of end; Therefore; Pore 3 distribution densities from opening 1 end to plug 4 blind ends on hollow pipeline 2 tube walls increase gradually, can make the interior oxygen of survival capsule more even like this.
Different according to survival capsule volume and shape, above-mentioned hollow pipeline 2 is linear, L shaped or arc hollow pipeline.Hollow pipeline 2 is the integrative-structure that stainless steel or plastics are processed.
During use, oxygen current-sharing pipe is installed in the survival capsule, an end of pore 3 little (or pore 3 distribution densities are little) is installed on the air inlet port of survival capsule, and an end of pore 3 big (or pore 3 distribution densities are big) is in survival capsule on the position away from air inlet port.Oxygen gets into oxygen current-sharing pipe from hollow pipeline 2 openings 1; Pore 3 through oxygen current-sharing pipe is discharged in the survival capsule; The gas pressure of air inlet port end is big; Terminal gas pressure is little, but because pore 3 sizes (perhaps distribution density) difference on the oxygen current-sharing pipe can make oxygen be evenly distributed in the survival capsule.The utility model also can be used for other closed containers are inflated.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of having done, remodeling, interpolation or replacement also should belong to the protection domain of the utility model.
Claims (5)
