Abstract
The utility model relates to the field of mine lifesaving, in particular to an oxygen supply system of a mine rescue capsule. The mine rescue capsule requires the oxygen supply system, for the underground environment is closed and requires sufficient oxygen supply; and the supply system is safe and reliable. The utility model adopts the technical scheme that the oxygen supply system comprises more than one high-pressure oxygen cylinder, and the high-pressure oxygen cylinder is connected with two pressure reducing valves and then connected with an oxygen supply port. More than one high-pressure oxygen cylinder is intensively connected through a bus bar. The two pressure reducing valves comprise a high pressure reducing valve and a low pressure reducing valve, the high-pressure oxygen cylinder is sequentially connected with the high pressure reducing valve and the low pressure reducing valve, and a pressure gauge is arranged on each valve. The utility model has the advantages that the oxygen supply system is safe and reliable, multi-times air change is not required, and oxygen flow can be manually adjusted. A pipeline of the oxygen supply system is used for delivering oxygen to a living capsule of the rescue capsule and controlling the oxygen delivery quantity to ensure that oxygen supply in the living capsule is in a reasonable and controllable range.
Description
Technical field
The utility model relates to mining lifesaving field, relates in particular to the mine escape capsule oxygen system.
Background technology
Mine escape capsule needs oxygen system, because subsurface environment seals, sufficient oxygen supply need to be arranged, and this supply system should be safe and reliable.
The utility model content
The utility model purpose: reliable for a kind of safety is provided, the mine escape capsule oxygen system that need not repeatedly take a breath.
In order to reach as above purpose, the utility model is taked following technical scheme: comprise more than one high-pressure oxygen cylinder, high-pressure oxygen cylinder connects oxygen supply port after by reducing valve.
The further technical scheme of the utility model is: described more than one high-pressure oxygen cylinder is concentrated by bus-bar and is connected.
The further technical scheme of the utility model is: described reducing valve has two, is respectively high-pressure pressure-reducing valve and low-pressure relief valve, and high-pressure oxygen cylinder passes through high-pressure pressure-reducing valve and low-pressure relief valve successively, and each valve is furnished with pressure meter.
The further technical scheme of the utility model is: described high-pressure oxygen cylinder by reducing valve after again through connecting again oxygen supply port behind the flow meter.
The further technical scheme of the utility model is: also comprise more than one hand-operated valve.
Adopt as above the utility model of technical scheme, have following beneficial effect: safety, reliable, need not repeatedly take a breath, can also the manual adjustments oxygen flow.The oxygen system pipeline is used for carrying out transporting of oxygen in the survival cabin of survival capsule, and can carry out the control of oxygen conveying capacity, is in rationally controlled scope to guarantee the oxygen supply in the survival cabin.
Description of drawings
In order to further specify the utility model, further describe below in conjunction with accompanying drawing:
Accompanying drawing is the structural representation of utility model:
Wherein: 1. transfer chamber cabin section; 2. survival cabin cabin section; 3. high-pressure oxygen cylinder; 4. hand-operated valve; 5. pressure meter; 6. reducing valve; 7. flow meter; 8. oxygen supply port.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described, embodiment does not consist of restriction of the present utility model:
Comprise more than one high-pressure oxygen cylinder 3, high-pressure oxygen cylinder 3 is by reducing valve 6 rear connection oxygen supply ports 8.
The further technical scheme of the utility model is: described more than one high-pressure oxygen cylinder 3 is concentrated by bus-bar and is connected.
The further technical scheme of the utility model is: described reducing valve 6 has two, is respectively high-pressure pressure-reducing valve and low-pressure relief valve, and high-pressure oxygen cylinder 3 passes through high-pressure pressure-reducing valve and low-pressure relief valve successively, and each valve is furnished with pressure meter.
The further technical scheme of the utility model is: described high-pressure oxygen cylinder 3 by reducing valve 6 after again through connecting again oxygen supply port 8 behind the flow meter 7.
The further technical scheme of the utility model is: also comprise more than one hand-operated valve 4.
Mainly by the high-pressure oxygen cylinder 3 of some, bus-bar, and control cabinet composition are equipped with two cover reducing valve, stop valve, gas flowmeter etc. to the oxygen system pipeline in the case.
Be mainly used to store the oxygen of breathing for personnel, what of its quantity can be equipped with according to survival capsule personnel's quantity and the hedging time.
The function of bus-bar mainly is that the gas cylinder of varying number is unified to connect central gas supply.Use the oxygen bus-bar can save the number of times that changes steel cylinder, alleviate workman's labour intensity, in use handled easily control, guarantee that simultaneously personnel take refuge in the cabin in comparatively mild state, reduce the release of waste heat, bus-bar centralized management high pressure oxygen can reduce the existence of potential safety hazard.Bus-bar can be saved the space, place simultaneously, better rationally utilizes the space, place.
Be the high-pressure oxygen cylinder air feed because of what adopt, general reducing valve can not meet the demands.So, need to install two reducing valve and carry out two-stage decompression.Its formation mainly contains high-pressure pressure-reducing valve and low-pressure relief valve.
The oxygen that high-pressure oxygen cylinder is stored carries out two-stage decompression by reducing valve, in survival cabin, satisfies personnel's respiratory demand in the cabin by Pipeline transport.The quantity of oxygen cylinder can be adjusted according to specified number in the cabin.
Oxygen cylinder, mainly being installed in the transfer chamber 1 of bus-bar is near a side of transfer chamber, six double placements of oxygen cylinder, three of every rows.By metallic conduit oxygen is sent into survival cabin 2.Mainly be two-stage decompression valve, through shut off valve and flow meter 7 in the control cabinet.It mainly is installed in the survival cabin, is convenient to so convenient control oxygen flow.
Oxygen concentration in the cabin can be monitored according to oxygen sensor, when oxygen concentration surpasses the bound of detector setting sound and light alarm can occur, and carries out the manual adjustments oxygen flow this moment.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; that describes in above-described embodiment and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in the claimed scope.
