Detailed description of the invention
As it can be seen, dirt door is caught in a kind of preventing wetting colliery, including gauze door 1, the top of described gauze door 1 is connected with sprayer unit 2, and sprayer unit 2 is externally connected with the water transport channel 4 with sprayer unit control valve 3；nullDescribed sprayer unit control valve 3 includes the first plate valve 5 and the second plate valve 12，First plate valve 5 includes first piece valve pocket 8，Second plate valve 12 includes second valve pocket 15，It is provided with the inlet channel 7 with aqueduct 4 UNICOM outside first piece valve pocket 8，It is provided with the outlet conduit 14 with aqueduct 4 UNICOM outside second valve pocket 15，It is linked with the first outlet conduit 10 and the first inlet channel 17 between first piece valve pocket 8 and the medial surface of second valve pocket 15、Second outlet conduit 11 and the second inlet channel 18，It is provided with first in first outlet conduit 10 or the second outlet conduit 11 and may move water outlet closure valve plug 9，It is provided with second in second outlet conduit 17 or the second inlet channel 18 and may move water outlet closure valve plug 16，First may move water outlet closure valve plug 9、Second may move water outlet closure valve plug 16 is connected to water outlet Guan Bi valve plug controller 6、Water outlet closes valve plug controller 13，First plate valve 5 and the handle of the second plate valve 12 and the horizontal range of described sprayer unit 2 are arranged between 0.5M～2M.
The water outlet Guan Bi valve plug controller 6 of the first plate valve 5 is handle, carries out Guan Bi switching for water outlet closure valve plug removable described in Non-follow control between described first outlet conduit 10 and the second outlet conduit 11；
The water inlet Guan Bi valve plug controller of described second plate valve is handle, carries out Guan Bi switching for water inlet Guan Bi valve plug removable described in Non-follow control between described first inlet channel 17 and the second inlet channel 18.
In the present embodiment, sprayer unit control valve uses Non-follow control, it is possible to achieve the Artificial Control to sprayer unit.When pedestrian is by when installing the first plate valve one side controlling sprayer unit by mending dirt door, first operates the handle of the first plate valve, will not be atomized when so by mending dirt door and drench；When by mending dirt door through out-of-date, then operating the handle of the second plate valve, such sprayer unit normally works, and sprays water smoke.
In above-described embodiment, specifically, described first plate valve 5 and the described handle of the second plate valve 12 and the horizontal range of described sprayer unit are arranged between 0.5M～2M, and for example, distance could be arranged to 1.5M；During it is to be understood that horizontal range refers to enter gauze door and leave gauze door operation handle, handle is from the distance of gauze door.
By setting a certain distance, it is to avoid when entering and leaving gauze door, the switch of sprayer unit causes pedestrian's health to be drenched.
In above-described embodiment, specifically, it is connected in series by a flexible pipe, optionally between the first outlet conduit 10 of described first plate valve 5 and the first inlet channel 17 of described second plate valve 12, it is also possible to be connected in series by threaded steel pipe；
It is connected in series by a flexible pipe, optionally between second outlet conduit 11 of described first plate valve 5 and the second inlet channel 18 of described second plate valve 12, it is also possible to be connected in series by threaded steel pipe.
It is connected in series by using flexible pipe or threaded steel pipe, it is to avoid in use two plate valve interfaces leak, and play good sealing function.
