Abstract
The utility model discloses a pressure ventilation and compressed air automatic-switching device for an escape capsule or a refuge chamber. A two-position three-way single pneumatic-control spring-return reversing valve (4) is arranged, and a mine pressure ventilation pipeline and a compressed air pipeline are respectively connected with two inlets of the two-position three-way single pneumatic-control spring-return reversing valve (4). A spray device (7) and an air curtain device (8) are respectively connected with outlets of the two-position three-way single pneumatic-control spring-return reversing valve (4), and a pilot control pipe (9) connected with the pilot control pressure end of the two-position three-way single pneumatic-control spring-return reversing valve (4) is arranged on the mine pressure ventilation pipeline. When a mine pressure ventilation system is normal, the air source of the spray device and the air curtain device of the escape capsule or the refuge chamber is provided by the pressure ventilation system. After the pressure ventilation system is damaged, the pressure ventilation and compressed air automatic-switching device for the escape capsule or the refuge chamber can automatically switch to compressed air. The traditional manual operation is solved, the delay operation is prevented, personal factors are removed, and the life safety of people is safeguarded to the largest extent.
Description
Technical field
The utility model relates to happen suddenly under a kind of coal mine in emergency circumstances distress personnel safety hedging employed packaged type hardware survival capsule or refuge chamber, is specially a kind of colliery packaged type survival capsule or refuge chamber and presses wind and compressed air automatic switching control equipment.
Background technology
In coal mine downhole safety hedging six big systems, a removable survival capsule and a refuge chamber that is used for urgent danger prevention is arranged, for hedging personnel's existence guarantee; Need introduce in the cabin mine compressed air or in the chamber, be used for hedging personnel's functions such as breathing, gas washing, the outer pernicious gas of cofferdam, after dangerous situation occurs pressing wind to be destroyed; Will the air of compressed air bottle be switched to spray and air curtain, in the prior art, be manual switchover mostly; Like this, be difficult to judge to press wind whether to destroy, only to feel under the weather and gone check system more at short notice the people; Like this with regard to danger close, and the people is difficult to expect check system especially in flurried, and causes maloperation easily; So just there is human factor, has hidden danger.
The utility model content
The utility model technical problem to be solved provide a kind of in the mine compressed air system just often; The spray of survival capsule or refuge chamber and the source of the gas of air curtain device are provided by compressed-air system; After compressed-air system destroyed, the source of the gas of spray and air curtain device can automatically switch to compressed-air actuated survival capsule or refuge chamber is pressed wind and compressed air automatic switching control equipment.
In order to solve the problems of the technologies described above; Survival capsule that the utility model provides or refuge chamber are pressed wind and compressed air automatic switching control equipment; Comprise mine compressed air pipeline, compressed air line, spray equipment and air curtain device; Be provided with a two-position three way list gas control spring reset reversal valve; Described mine compressed air pipeline is connected with two inlets of described two-position three way list gas control spring reset reversal valve respectively with compressed air line; Outlet with described two-position three way list gas control spring reset reversal valve is connected described spray equipment with air curtain device, and described mine compressed air pipeline is provided with guide's control valve that is connected with guide's controlled pressure end of described two position three way directional control valve 4.
Described mine compressed air pipeline is composed in series by mine compressed air, pressure wind master switch and strainer.
Described compressed air hose route compressed air gas source and air pressure switch are composed in series.
Adopt the survival capsule or the refuge chamber of technique scheme to press wind and compressed air automatic switching control equipment; At mine compressed air pipeline and compressed air line to adding a two-position three way list gas control spring reset reversal valve between spray equipment and the air curtain device; From the mine compressed air pipeline, draw the guide controlled pressure of one gas as two-position three way list gas control spring reset reversal valve; When compressed-air system just often; The pressure of compressed-air system makes the switching-over of two-position three way list gas control spring reset reversal valve, the mine compressed air pipeline is communicated, after mine compressed air is destroyed with spray equipment and air curtain device; Compressed-air system pressure disappears; The guide's controlled pressure disappearance two-position three way list gas control spring reset reversal valve that is two-position three way list gas control spring reset reversal valve leans on spring reset, and compressed air line is communicated with spray equipment and air curtain device, has accomplished mine compressed air and compressed-air actuated automatic switchover.
In sum, the utility model be a kind of in the mine compressed air system just often, the spray of survival capsule or refuge chamber and the source of the gas of air curtain device are provided by compressed-air system; After compressed-air system destroys; The source of the gas of spray and air curtain device can automatically switch to compressed-air actuated survival capsule or refuge chamber is pressed wind and compressed air automatic switching control equipment, has solved traditional manual operation, prevents to incur loss through delay operation; Get rid of human factor, ensure people's life security to greatest extent.
Description of drawings
Fig. 1 is the schematic diagram of the utility model.
Among the figure:
1, mine compressed air; 2, press the wind master switch; 3, strainer; 4, two-position three way list gas control spring reset reversal valve; 5, air pressure switch; 6, compressed air gas source.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Referring to Fig. 1; Mine compressed air 1, pressure wind master switch 2 and strainer 3 series connection backs are connected with an inlet of two-position three way list gas control spring reset reversal valve 4; Compressed air gas source 6 is connected with another inlet of two-position three way list gas control spring reset reversal valve 4 with air pressure switch 5 series connection backs; The outlet of two-position three way list gas control spring reset reversal valve 4 is connected with air curtain device 8 with spray equipment 7, draws guide's control valve 9 that is connected with guide's controlled pressure end of two-position three way list gas control spring reset reversal valve 4 behind the strainer 3.
As shown in Figure 1; Mine compressed air 1 is through pressing wind master switch 2, strainer 3; One gas is to the pilot port of two-position three way list gas control spring reset reversal valve 4; Promote 4 switching-overs of two-position three way list gas control spring reset reversal valve, mine compressed air 1 arrives air curtain device 8 and spray equipment 7 through two-position three way list gas control spring reset reversal valve 4.After mine compressed air 1 is destroyed; System pressure disappears; The pilot port pressure of two-position three way list gas control spring reset reversal valve 4 disappears; Two-position three way list gas control spring reset reversal valve 4 leans on spring reset, and compressed air gas source 6 is communicated with air curtain device 8 and spray equipment 7 through air pressure switch 5 and two-position three way list gas control spring reset reversal valve 4, has realized the automatic switchover of mine compressed air 1 with compressed air gas source 6.
