Abstract
The utility model discloses an automatic switching device for an escape capsule or refuge chamber air refrigeration pipe hot air opening, wherein a hot air opening of an air refrigeration pipe (1) is connected with an inlet opening of a two-position two-way normally closed pneumatic control shaft valve (3), an outlet opening of the two-position two-way normally closed pneumatic control shaft valve (3) is connected with the outside, a pneumatic control pipe of the two-position two-way normally closed pneumatic control shaft valve (3) is connected with an end of a pilot control pipe (2), and the other end of the pilot control pipe (2) is connected with an inlet opening of the air refrigeration pipe (1). The automatic switching device for an escape capsule or refuge chamber air refrigeration pipe hot air opening is characterized in that the two-position two-way normally closed pneumatic control shaft valve (3) is automatically opened through the pilot control pipe (2) when the inlet opening of the air refrigeration pipe (1) is under pressure, and therefore the hot air opening of the air refrigeration pipe (1) is communicated with the outside, and the air refrigeration pipe (1) work normally; and when inlet opening pressure of the air refrigeration pipe (1) disappears, the two-position two-way normally closed pneumatic control shaft valve (3) is automatically closed under the action of spring force, and the hot air opening of the air refrigeration pipe (1) is turned off.
Description
Technical field
The utility model relates to happen suddenly under a kind of coal mine in emergency circumstances employed movable hard rescue capsule of distress personnel safe or refuge chamber, is specially a kind of movable mining rescue capsule or refuge chamber air cooling pipe hot-air mouth recloser.
Background technology
In coal mine downhole safety hedging six large systems, movable escape capsule and a refuge chamber that is used for urgent danger prevention is arranged, living guarantee for the hedging personnel, need to utilize mine compressed air to carry out the separation of cold and hot air by the vortex generator of air cooling pipe, part thermal current is discharged to outside the cabin (chamber) through control valve by the hot-air mouth of air cooling pipe, another part cold airflow is in the cold wind mouth is discharged to cabin (chamber), reduce the interior temperature in cabin (chamber), when having compressed air to enter the entrance of air cooling pipe, need to open the control valve of air cooling pipe hot-air mouth, hot blast is discharged to outside the cabin (chamber), the air cooling pipe could work like this, when the entrance of air cooling pipe does not have pressure, will close the control valve of air cooling pipe hot-air mouth, otherwise cabin (chamber) outer toxic and harmful will enter in the cabin (chamber).In the prior art, the control valve at air cooling pipe hot-air mouth place is manual control mostly, like this, when the air cooling pipe is opened, if can not in time open the control valve at hot-air mouth place, the air cooling pipe is with regard to cisco unity malfunction, when the air cooling pipe quits work, if can not in time close the control valve at hot-air mouth place, the outer toxic and harmful in cabin (chamber) will enter in the cabin (chamber), like this with regard to danger close, and the people forgets operation especially easily in flurried, has hidden danger.
The utility model content
Technical problem to be solved in the utility model provides a kind of hot-air mouth that can in time automatically open or close the air cooling pipe, thereby guarantees survival capsule or the refuge chamber air cooling pipe hot-air mouth recloser of safety in survival capsule or the refuge chamber.
In order to solve the problems of the technologies described above, the survival capsule that the utility model provides or refuge chamber air cooling pipe hot-air mouth recloser, comprise the air cooling pipe, the hot-air mouth of described air cooling pipe is connected with the entrance of bi-bit bi-pass normally closed type gas control axle valve, the outlet of described bi-bit bi-pass normally closed type gas control axle valve is connected with extraneous, the pneumatic tubes of described bi-bit bi-pass normally closed type gas control axle valve is connected with an end of pilot control pipe, and the other end of described pilot control pipe is connected with the entrance of described air cooling pipe.
Adopt survival capsule or the refuge chamber air cooling pipe hot-air mouth recloser of technique scheme, add a bi-bit bi-pass normally closed type gas control axle valve at the hot-air mouth place of air cooling pipe, draw one gas from the entrance of air cooling pipe as the pilot control pressure of bi-bit bi-pass normally closed type gas control axle valve, when having pressure, the air cooling tube inlet makes the commutation of bi-bit bi-pass normally closed type gas control axle valve by the pilot control pipe, the hot-air mouth of air cooling pipe is communicated, the normal operation of air cooling pipe with the external world.After air cooling tube inlet pressure disappeared, bi-bit bi-pass normally closed type gas control axle valve resetted under the effect of spring force, cut off the hot-air mouth of air cooling pipe, thus realize air cooling pipe hot-air mouth with the keying of air cooling pipe automatic switch.The utility model has solved traditional manual operation, prevents from forgetting operation, gets rid of human factor, ensures to greatest extent people's life security.
In sum, the utility model is a kind of hot-air mouth that can in time automatically open or close the air cooling pipe, thereby guarantees survival capsule or the refuge chamber air cooling pipe hot-air mouth recloser of safety in survival capsule or the refuge chamber.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, the entrance of air cooling pipe 1 is connected with compressed air hose 6, the hot-air mouth of air cooling pipe 1 is connected with the entrance of bi-bit bi-pass normally closed type gas control axle valve 3, the outlet of bi-bit bi-pass normally closed type gas control axle valve 3 is connected with cabin (chamber) outer 4, the pneumatic tubes of bi-bit bi-pass normally closed type gas control axle valve 3 is connected with an end of pilot control pipe 2, the other end of pilot control pipe 2 is connected with the entrance of air cooling pipe 1, and the cold wind outlet of air cooling pipe 1 is connected with cabin (chamber) interior 5.
As shown in Figure 1, the compressed air part of the compressed air hose 6 of mine is carried out the separation of cold and hot air through the vortex generator of air cooling pipe 1, part thermal current is discharged to cabin (chamber) outer 4 by the hot-air mouth of air cooling pipe 1, another part cold airflow is in the cold wind mouth is discharged to cabin (chamber) 5, compressed-air actuated another part promotes 3 commutations of bi-bit bi-pass normally closed type gas control axle valve through pilot control pipe 2, and the hot-air mouth of air cooling pipe 1 is opened; When not having compressed air, air cooling pipe 1 inlet pressure disappears, and the pilot port pressure of bi-bit bi-pass normally closed type gas control axle valve 3 disappears, and valve is by spring reset, the hot-air mouth of air cooling pipe 1 is closed, and the hot-air mouth of having realized air cooling pipe 1 is automatic switch with the keying of air cooling pipe 1.
Claims (1)
1. a survival capsule or refuge chamber air cooling pipe hot-air mouth recloser, comprise air cooling pipe (1), it is characterized in that: the hot-air mouth of described air cooling pipe (1) is connected with the entrance of bi-bit bi-pass normally closed type gas control axle valve (3), the outlet of described bi-bit bi-pass normally closed type gas control axle valve (3) is connected with extraneous, the pneumatic tubes of described bi-bit bi-pass normally closed type gas control axle valve (3) is connected with an end of pilot control pipe (2), and the other end of described pilot control pipe (2) is connected with the entrance of described air cooling pipe (1).
