| description | The underground dust falling and spraying three-control switch device comprises a roadway main water supply pipe, the roadway main water supply pipe is connected with an L-shaped three-way valve 1 through a pipeline, and the L-shaped three-way valve 1 is connected with a branch water supply rubber pipe 5 and a branch water supply rubber pipe 6. One end of the branch water supply rubber pipe 5 and one end of the branch water supply rubber pipe 6 are connected with the same L-shaped four-way valve 3, and the L-shaped four-way valve 3 is connected with a branch water supply rubber pipe 7 and a branch water supply rubber pipe 8. The device is composed of two L-shaped three-way valves, an L-shaped four-way valve, a spraying pipe, a spraying nozzle and a plurality of water supply rubber pipes, and the two L-shaped three-way valves and the L-shaped four-way valve are installed outside the maximum range of dust fall spraying so as to control starting and stopping of spraying of the roadway three-way intersection.
