As it is shown in figure 1, high-precision gas air distributing device described in the utility model, valve control module 100 and flow-control module 200 is selected to form.Wherein, valve control selects module 100 to include that three tunnels are respectively provided with the normally closed air inlet electromagnetic valve of disjunctor (101；102；103) air inlet pipeline, two tunnels are respectively provided with the normally closed electromagnetic valve (104 of giving vent to anger of disjunctor；105) outlet pipe (two road outlet pipe one tunnel output SF6Target gas, another road output O2Target gas), distribution select switch 106 (three cuttves three are thrown distribution and selected rotary switch), interface of giving vent to anger to select switch 107 (two two, cuttves give vent to anger interface select to stir pass open) and Switching Power Supply.Distribution selects switch 106 to connect the normally closed air inlet electromagnetic valve of disjunctor (101 controlled on three road air inlet pipelines respectively；102；103).Interface of giving vent to anger selects switch 107 to connect the normally closed electromagnetic valve (104 of giving vent to anger of disjunctor controlled on two road outlet pipes respectively；105).Distribution selects switch 106 and interface of giving vent to anger to select switch 107 connecting valve power supply respectively.Flow-control module 200 includes that two are respectively provided with regulation valve (203 of giving vent to anger；204) mass flow device (201；202), a valve control selects rotary switch 205 (rotary switch thrown by three cuttves three of band delay circuit 206) and two voltmeter heads (207；208) (three and half digital display voltmeter heads).Valve control select rotary switch 205 respectively connects control two give vent to anger regulate valves (203；204).Each voltmeter head (207；208) a mass flow device (201 is each connected；202).In three road air inlet pipelines, two-way (meets SF respectively6Source gas and O2Source gas) as the first air inlet pipeline quality of connection flow calorimeter, a remaining road air inlet pipeline (meets N2Source gas) connect another mass flow device as the second air inlet pipeline.
As in figure 2 it is shown, three the normally closed air inlet electromagnetic valves of disjunctor, two the normally closed electromagnetic valves of giving vent to anger of disjunctor, distribution selection switch, interfaces of giving vent to anger select to switch and control to connect by five way solenoid valve drive circuits realizations between this.Carrying out practically process is as follows:
1. valve control selects switch at ' zero-bit ' shelves, is switched to ' SF6' distribution shelves time, zero level be transformed to high level (5V) and start optically isolated drive circuit, optically isolated drive circuit is become conducting state from cut-off state, and the coil of electromagnetic valve, by electricity, starts corresponding ' SF6、N2' air inlet electromagnetic valve and ' SF6' electromagnetic valve of giving vent to anger becomes opening state from closed mode, enters ' SF6' distribution duty.
2. valve control selects switch by ' SF6' distribution shelves are switched to ' O2' distribution shelves time, be first switched to ' zero-bit ' shelves, enter back into ' O2' distribution shelves, now by high level vanishing level, close all of intake valve and air outlet valve, then become high level from zero level, open ' O2、N2' air inlet electromagnetic valve and ' O2' electromagnetic valve of giving vent to anger, enter ' O2' distribution duty.
3. interface of giving vent to anger selects to switch when " the next shelves ", SF6、O2Electromagnetic valve of giving vent to anger is selected on-off control, SF by distribution6、O2Air inlet electromagnetic valve duty is constant, and two roads interface of giving vent to anger is that respective correspondence is given vent to anger interface gas transmission.
4. interface of giving vent to anger selects to switch when " upper shelves ", O2The power supply of electromagnetic valve of giving vent to anger is disconnected, ' O now2' electromagnetic valve of giving vent to anger is closed mode, but SF6The power supply of electromagnetic valve of giving vent to anger is switched to N2Air inlet electromagnetic valve feeder ear, is selected on-off control by distribution, it is achieved two roads interface of giving vent to anger is route SF6Give vent to anger interface gas transmission.
As shown in Figure 3 a and Figure 3 b shows, the gas transmission pipeline related in whole device is mainly connected into gas transmission pipeline by air inlet pipeline and outlet pipe.Gas transmission pipeline mainly by one three enter two go out pipeline combiner, 2000 milliliters of mass flow controller, 500 milliliters of mass flow controller, one two enter one and go out threeway double card bell and spigot joint, an one-in-and-two-out pipeline combiner etc. and form.Air inlet is entered the two three tunnel air inlets fast twist-on heads going out pipeline combiner by three and is docked 6 millimeters of PU pipes respectively, and 6 millimeters of PU pipe other ends connect three kinds of source of the gas (SF after decompression respectively6、O2、N2) output interface.Three enter two two roads going out pipeline combiner double card bell and spigot joint of giving vent to anger docks 6 millimeters of PU pipe respectively, the other end of 6 millimeters of PU pipes docks corresponding two mass flow controller air inlet double card bell and spigot joints respectively, the other end of mass flow controller double card bell and spigot joint of giving vent to anger docks 6 millimeters of PU pipe respectively, 6 millimeters of PU pipe other ends are docked corresponding two respectively and are entered one and go out threeway air inlet double card bell and spigot joint, two enter one goes out threeway double card bell and spigot joint of giving vent to anger and docks 6 millimeters of PU pipe, the air inlet double card bell and spigot joint of 6 millimeters of PU pipe other end docking one-in-and-two-out pipeline combiners, two tunnels of one-in-and-two-out pipeline combiner give vent to anger fast twist-on head connect 6 millimeters of latex flexible pipes, 6 millimeters of latex flexible pipe other ends connect test specimen respectively.Two of one-in-and-two-out pipeline combiner give vent to anger the coffret that fast twist-on head is target gas.
As shown in Figure 4, valve control selects rotary switch to be that three cuttves three with delay function are thrown distribution and selected rotary switch, selects the automatic control of two tunnel mass flow devices, closes, washes pipe duty.Control end function according to flow controller, it is closed mode that definition control end to connect+15V, and control end connection-15V, for washing tubulose state, controls end unsettled for automatic control state.
Valve control selects rotary switch when " close stance ", it is closed mode that the governor valve control end of mass flow device connects+15V, when valve control selects switch by " close stance " rotation direction " automatic control position ", the governor valve control end of mass flow device connects the normal splice grafting point connection-15V of delay circuit, mass flow device enters and washes tubulose state, delay circuit connects+5V power supply simultaneously, wait 5 seconds, the normal splice grafting point of delay circuit automatically switches to off-state, the governor valve control end of mass flow device is unsettled, and the regulation valve of mass flow device enters and arranged value controlled state.
Valve control selects rotary switch to be closed mode by " automatic control position " rotation direction " close stance ", the governor valve control end of mass flow device by the unsettled+15V power end that is switched to, the regulation valve of mass flow device.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
