Description
Technical field
The present invention relates to a kind of automaton, be specifically related to a kind of refuge chamber air curtain spray automatic switching control device.
Background technology
Mine refuge underground chamber is country's the Eleventh Five-Year Plan period great science and technology supporting project, it is the key technology that a primary study solves mine disaster emergency management and rescue, and the wherein reliable and stable work of air curtain spray system, easy and simple to handle, for raising hedging efficiency, the life at utmost saving mine staff is significant; The automaticity of raising air curtain spray system and ease-to-operate are important problems.Therefore, for refuge chamber air curtain spray system provides a kind of reliable automatic pneumatic switching device shifter very necessary.The switching device shifter of mine compressed air and compressed air bottle must be easy and simple to handle, and reliable operation, could save the time entering refuge chamber, saves compressed air resource limited in refuge chamber, improves hedging efficiency.Its major function of automatic pneumatic switching device shifter realizes the pressure wind air feed of air curtain spray system in refuge chamber and the automatic switchover of compressed air air feed, effectively can ensure the normal gaseous environment that cave indoor occupant is survived.
At present, the mine compressed air of refuge chamber air curtain spray system and the pneumatic switching device shifter majority of compressed air air feed are for manually switching, complex operation, easy generation maloperation, incur loss through delay the time that hedging personnel enter refuge chamber, well can not keep normal gaseous environment in chamber, the drawback of hand-operated pneumatic switching device shifter is more.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and it is simple that technical problem to be solved there is provided a kind of structure, easy to use, the refuge chamber air curtain spray automatic switching control device of automatic switchover supply air line.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: refuge chamber air curtain spray automatic switching control device, comprise: shuttle valve, two-position five-way Pneumatic valve, rotary cylinder, Pneumatic three-way ball valve, described Pneumatic three-way ball valve is connected with mine compressed air air inlet pipe and compressed air inlet pipe, described mine compressed air air inlet pipe is connected with shuttle valve by the first pipeline, described compressed air inlet pipe is connected with shuttle valve by the second pipeline, described first pipeline is connected with two-position five-way Pneumatic valve by the 3rd pipeline, the outlet side of described shuttle valve is connected with the inlet end of two-position five-way Pneumatic valve, the gas outlet of described two-position five-way Pneumatic valve is connected with the porting of rotary cylinder respectively, the piston rod of described rotary cylinder is connected with the control lever of Pneumatic three-way ball valve.
Described first pipeline, the second pipeline and the 3rd pipeline are stainless steel cleaning pipe.
The beneficial effect that the present invention is compared with prior art had is: mine compressed air and compressed air are accessed air curtain spray system by the present invention simultaneously, and ensures preferentially to use mine compressed air; After mine compressed air is destroyed, automatically switch to compressed air air feed, without the need to manual operation, avoid maloperation, save compressed air resource, save the time that hedging personnel enter refuge chamber; Simultaneously rotary cylinder and Pneumatic three-way ball valve directly integrated, volume is little, and reliability is high.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the right view of Fig. 1.
In figure: 1 is shuttle valve, 2 is two-position five-way Pneumatic valve, and 3 is rotary cylinder, and 4 is Pneumatic three-way ball valve, and 5 is mine compressed air air inlet pipe, and 6 is compressed air inlet pipe, and 7 is the first pipeline, and 8 is the second pipeline, and 9 is the 3rd pipeline.
Detailed description of the invention
As Fig. 1, shown in Fig. 2, refuge chamber air curtain spray automatic switching control device, comprise: shuttle valve 1, two-position five-way Pneumatic valve 2, rotary cylinder 3, Pneumatic three-way ball valve 4, described Pneumatic three-way ball valve 4 is connected with mine compressed air air inlet pipe 5 and compressed air inlet pipe 6, described mine compressed air air inlet pipe 5 is connected with shuttle valve 1 by the first pipeline 7, described compressed air inlet pipe 6 is connected with shuttle valve 1 by the second pipeline 8, described first pipeline 7 is connected with two-position five-way Pneumatic valve 2 by the 3rd pipeline 9, the outlet side of described shuttle valve 1 is connected with the inlet end of two-position five-way Pneumatic valve 2, the gas outlet of described two-position five-way Pneumatic valve 2 is connected with the porting of rotary cylinder 3 respectively, the piston rod of described rotary cylinder 3 is connected with the control lever of Pneumatic three-way ball valve 4.
Described first pipeline 7, second pipeline 8 and the 3rd pipeline 9 are stainless steel cleaning pipe.
In the present invention, Pneumatic three-way ball valve 4 has two air inlet ports and a gas outlet, two air inlet ports are connected with compressed air inlet pipe 6 with mine compressed air air inlet pipe 5 respectively, and a gas outlet is the air supply opening connecing air curtain spray system pipeline.Mine compressed air air inlet pipe 5 is connected with shuttle valve 1 with the second pipeline 8 respectively by the first pipeline 7 with compressed air inlet pipe 6, and be 0.3Mpa at shuttle valve place setting compressed air pressure, pressure wind pressure is 0.6MPa, first pipeline 7 is also connected with two-position five-way Pneumatic valve 2 by the 3rd pipeline 9 simultaneously, as control gas circuit.When mine compressed air exists, its pressure ratio compressed air pressure is high, and shuttle valve 1 commutates to mine compressed air position, and two-position five-way Pneumatic valve 2 is open-minded, and pressure wind enters rotary cylinder 3, piston rod rotation, drives Pneumatic three-way ball valve 4 to rotate, and opens pressure wind air feed; When mine compressed air destroys, on shuttle valve 1, compressed air pressure is higher than mine compressed air pressure, and compressed air gas circuit is opened in shuttle valve 1 commutation, two-position five-way Pneumatic valve 2 commutates simultaneously, and compressed air enters rotary cylinder 3, piston rod rotation, drive Pneumatic three-way ball valve 4 to rotate, open compressed air air feed.Thus the automatic switchover realized between mine compressed air and compressed-air actuated two-way air feed, ensure preferentially to use mine compressed air simultaneously, easy and simple to handle, reliability is high, save the time that hedging personnel enter chamber, hedging efficiency is high, saves in chamber and provides compressed air resource for oneself.
During mine generation catastrophe, hedging personnel enter the transition chamber of refuge chamber by mine laneway, if mine compressed air is not destroyed, mine compressed air controls air curtain spray and uses; If mine compressed air is destroyed, automatically switch to compressed air supply air curtain spray and use, without the need to manual operation, avoid maloperation, effectively ensure normal gaseous environment in chamber.
By reference to the accompanying drawings embodiments of the invention are explained in detail above, but the present invention is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from present inventive concept.
