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...

Abstract

The invention provides a collecting bar type multi-gas separating / regulating / controlling device for a mining rescue capsule, which is characterized by comprising at least three collecting bars, wherein the at least three collecting bars are connected with a separating / regulating / controlling box through the respective pipeline, the separating / regulating / controlling box comprises at least three flowmeters, and each collecting bar is connected with one different flowmeter through the respective pipeline; or gas in any two collecting bars is firstly collected, then separated by an inlet gas separating switch and transmitted into two different flowmeters, and the outlet of each flowmeter is respectively connected to one different gas outlet; or the outlets of any two flowmeters are connected by one outlet gas separating switch and then respectively connected to two different gas outlets, and each gas outlet is respectively connected to one pneumatic device. The device provided by the invention has a simple structure, can realize dispersed arrangement and is flexible to install and use; each collecting bar can respectively control the output pressure for different functions; and the energy of compressed gas can be fully used after gas collection and separation.

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...
