About plumbing installation 26 and air-flow, with reference to figure 1.In one embodiment, every 2 to 8 4.5K compressed gas cylinder 22 by each how valve is not connected in parallel to compression gas pipeline.This gas pipeline carries compressed air from compressed gas cylinder 22 to system valve 68.System valve 68 controls the air-flow flowing through gas pipeline from compressed gas cylinder 22, opens or closes.System valve 68 is closed in build process, but once build, and compressed gas cylinder 22 is connected to appendix, and transition station 10 has been ready to can work and deliver to mine, and so system valve 68 will be opened, and allows Compressed Gas to flow through system valve 68.This constantly runs in systems in which.Bottle pressure meter is connected on the pipeline between compressed gas cylinder 22 and system valve 68, to test in the operation of each order of classes or grades at school.
Appendix is from system valve 68(Parker Veriflo HCV valve) extend to next step valve 70(Parker Veriflo two stage pressure regulator IR 6004, inlet pressure ranges 10-250 PSIG), 4.5k PSI pressure in pipeline is reduced to the pressure worked of about 100 PSI by this, is supplied to downstream valve.Appendix extends to an activator switch 40(such as Parker Veriflo door from next step valve 70 that it separates and activates two-position three way directional valve P/N 47000074), door activates valve (as Parker Veriflo NV17 AOP valve) and main valve 46(as three way cock 48 or position valve 48, Parker Veriflo NV17 indicator valve, can be operated in unlatching, close and dormant state).
Position valve 48 is maintained in its closed position, until miner needs to use transition station 10.In fastening position, position valve 48 stops any compressed air stream through it.When miner needs to use transition station 10, they forward position valve 48 to enable possition.Before miner enters transition station 10, from the external control position valve 48 at transition station 10.In the present embodiment, valve 48 and 6.48 CFM aperture 56, compressed-air actuated airflow passes position, by the exhaust silencer 32(that extends to the rear being positioned at room as, Parker Veriflo noise damper P/N 47000075) appendix enter into the room at transition station 10.Before miner enters room, by forwarding the position of position valve 48 to enable possition, to produce malleation to limit or to stop the gas from mine environment to enter transition station 10.When miner withdraws this room, they forward position valve 48 to standby position, make the continuous flow of air can flow through a valve 48 and eat dishes without rice or wine 56 to come exhaust silencer 32 by appendix through 6 CFM.At standby position, air continues to enter room with much lower speed, and waiting for may need its any miner in the time subsequently, still malleation is maintained when entering room, but air enters with enough low speed, to extend the duration worked at transition station 10.
From next step valve 70, appendix also extends to an activation valve by door activator switch 40.Door activation valve allows compressed air to incorporate the air of self-alignment valve 48, enters room by exhaust silencer 32.When door activator switch 40 is opened, Compressed Gas flows through this activator switch 40, and flows through an activation valve, flows to activate valve from door and extend to 6.48 CFM apertures 56 appendix of exhaust silencer 32.Door activator switch 40 is exactly: no matter when door 14 opens how many, and door activator switch 40 is opened, and allows compressed air to flow to an activation valve by appendix, and enters room by exhaust silencer 32.If position valve 48 is also opened, so flow through a gas of the appendix of activation valve and make in fact the flow velocity of the air entering room double.When air is delivered to an activation valve from door activator switch 40, door activates valve and opens, but prevents air stream from flowing back to an activator switch 40 from exhaust silencer 32 in reverse direction.In this way, whenever door 14 is opened to arbitrarily angled, the air stream of increase will be applied to room to maintain malleation, and stop mine environment.
Door activator switch 40 as shown in Figure 2 has button 80, and this button 80 is located in the doorframe 82 of hinge 86 side of door 14, as shown in Figure 9.This button 80 is spring loaded, thus when door 14 is even open a bit, interval will be produced between door 14 and doorframe, button 80 is by outwards movement under the effect of spring 84, be drawn through the handle 88 that switch 40 extends into the button 80 of runner 90 and leave this runner 90, make air flow through runner 90 in switch 40, and flow to door and activate valve 50.Then, air flows through an activation valve 50, and flows to exhaust silencer 32 by appendix.When door 14 is closed, button 80 pushes away downwards by door 14, and traction handle 88 is got back in runner 90, this by closing switch 40 and stop air flow door activate valve.Activate 6.48 CFM in valve downstream, 56 permission air of eating dishes without rice or wine at door and flow to exhaust silencer 32 with 6.48 CFM from door activator switch.
As a kind of safety measure, be provided with safety valve 92 in the upper right corner at rear, steel room 16, if necessary, any excess air pressure can be discharged from room, as shown in Figure 4.In a preferred embodiment, in transition station, carbon dioxide scrubbing systems is not had to eliminate carbon dioxide.When miner is at transition station, poison gas (as carbon dioxide) is discharged with the lasting air stream entering room 16 or stops poison gas to enter by malleation effectively that maintain in transition station 10, this is less than one hour or two hours, miner has time enough to carry out self supply, take a break, and determine next which is gone to.
In another embodiment, Fig. 2 is the schematic diagram of plumbing installation, and Fig. 3 A, 3B, 3C are respectively the top view of console 42, lateral view and front elevation drawing.The schematic diagram of plumbing installation layout and the layout of Fig. 1 slightly different, and substantially to work in an identical manner, except there is following difference.As can be seen from the schematic diagram of plumbing installation, the air stream from compressed gas cylinder will flow to system valve 68, with the Parker Veriflo HCV valve of HP batchmeter.Air-flow is parked in that until valve 68 is opened.This means what system was normally closed, until valve 68 is opened.Once open valve 68, air-flow can flow to both direction.
1) air-flow can flow to main valve 46, Parker Veriflo NV17 indicator valve (" unlatching " or " stand-by " value);
2) air-flow can flow to auxiliary valve, and Parker Veriflo door activates two three tunnels and leads to normally closed switch.
In the console 42 shown in Fig. 1,2 and 3A-3C, miner will be apprised of a Parker Veriflo NV17 by explanatory note and indicate main valve to forward " unlatching " position to, thus first air-flow will flow through valve 46, and flow into exhaust silencer 32 by 6.48 CFM apertures 56.Once, miner opens door 14 and enters in room 16, Parker Veriflo door activator switch 40 will be activated, air stream also will import Parker Veriflo NV17 AOP auxiliary valve 50 by switch 40, and joined the air stream flowing through Parker Veriflo NV17 instruction main valve 46 by 6.48 CFM apertures 56, and the flow velocity of about 13 cfm is discharged.Switch 40 and AOP auxiliary valve 50 are to work with the mode that switch 40 recited above and door activate valve identical.
After whole miner enters into transition station, door 14 will be closed, and switch 40 also will be shut.Then, air stream will only flow to Parker Veriflo NV17 by " unlatching " position and indicate main valve, and air-flow will flow out exhaust silencer 32 with 6.48 cfm.Once miner leaves transition station, they will walk back console, and indicate main valve to forward to " stand-by " Parker Veriflo NV17, then, the air-flow flowing to exhaust silencer will be 0.6 cfm.
According to console, miner need perform step be:
1, the Parker Veriflo HCV system valve (in Fig. 2 leftmost valve) with HP batchmeter is opened;
2, main valve is indicated to forward " unlatching " position (in the middle part of Fig. 2 rightmost valve) to Parker Veriflo NV17;
3, open entrance gate, enter transition station:
A. wherein, mechanically operated Parker Veriflo door activator switch will be activated, and miner does not need to know this point, because they do not need to open or activate this switch;
4 once everyone enters in transition station, closes entrance gate:
A. wherein, mechanically operated Parker Veriflo door activator switch will lose efficacy;
5, leave miner and close entrance gate, going to console, indicating main valve to forward " stand-by " position to Parker Veriflo NV17.
Above-mentioned steps can continued operation, until all discharge from the air of compressed gas cylinder 22, or all miner has been this transition station.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
