Description

technical field

[0001] The invention relates to a confluence bar multi-gas diversion adjustment control device for a mine rescue cabin, which can be used in an emergency avoidance system in a coal mine, and is used for supplying compressed gas of a pneumatic fan, oxygen supply, spraying and air curtain system and Shunt regulation is used. Background technique

[0002] The rescue cabin is often used in the coal mine emergency avoidance system. After an accident, the underground workers hide in the rescue cabin for refuge. In order to prevent the intrusion of external toxic and harmful gases and ensure the normal operation of equipment in the cabin and the survival of personnel, it must be equipped with gas supply control pipelines for air curtain, spray, oxygen supply, operation of pneumatic equipment and positive pressure maintenance. In the current emergency avoidance system, compressed air and oxygen are directly discharged into the cabin after adjusting the pressure, wh...

Embodiment Construction

[0013] In order to make the present invention more comprehensible, a preferred embodiment is described in detail below with accompanying drawings.

[0014] like figure 1 As shown, the multi-gas diversion adjustment and control equipment for a mining rescue cabin provided by this embodiment includes three sets of bus bars for converging gases from different gas sources, that is, the first bus bar 17 and the second bus bar. Row 18 and the third busbar 19, the three groups of busbars are connected to the diversion adjustment control box through their respective pipelines.

[0015] Among them, the first busbar 17 is mainly used for the power source of the pneumatic equipment in the cabin, partial oxygen supply and positive pressure maintenance. It includes eight four-way valves 1, and the four four-way valves 1 are respectively connected in series and then connected in parallel to form a confluence pipeline. , the confluence pipeline is connected to the diversion regulation contr...
