Specific embodiment
The present invention will be further described in detail with reference to the embodiments and the accompanying drawings, but the implementation of the utility model
Mode is without being limited thereto.
Referring to Figures 1 and 2, the wet device of a kind of new gas control oxygen control, including sequentially connected level-one triple valve 1, drying
Device 3, level-one tempering tank 4, humidifier 7, second level triple valve 6 and second level tempering tank 8, the level-one triple valve 1 pass through piping connection
Oxygen analyser 2, the second level tempering tank 6 pass through piping connection hygrometer 9, the level-one triple valve 1, oxygen analyser 2, second level triple valve
6, hygrometer 9 is electrically connected with PLC controller 5 respectively；The level-one triple valve 1,6 structure of second level triple valve are the same, respectively include
There are one outlet pipes 15 for 14, two motor 10, valve body 11, spool air inlet pipelines, on the diagram, air inlet pipeline are as follows: pipeline 12
With pipeline 16；The shape of the spool 14 is shuttle shape, and the shuttle shape movable chamber 13 of spool 14, two air inlets are equipped in valve body 11
Pipeline, pipeline 12 and pipeline 16 are separately connected two opposite ends of shuttle shape movable chamber 14, and outlet pipe 15 connects shuttle shape movable chamber 13
Middle part, principle is: motor 10 by PLC controller 5 control band movable valve plug 14 up or down move, when spool 14 is past
