As depicted in figure 5 and figure 12, described fluid mixer includes runner 38, hybrid chamber 39 and gaseous mixture delivery outlet 40；It is hybrid chamber 39 in the center hollow round column boss of described bottom end cover column base 5；Described runner 38 connects venthole 31 bottom；Described hybrid chamber 39 connects runner 38 and exports；Described gaseous mixture delivery outlet 40 connects the outlet of hybrid chamber 39.
Pressure compensation process:
When ternary gas enters in tubular spool 7 from upper end cover air inlet 11 and spool air inlet 13 respectively, shunting is realized in tubular spool 7, major part gas enters spool venthole 14, the gas of fraction enters top pressure chamber 15 by pressure stable hole 17, is then connected to the bottom regulator hole 19 of another yuan of gas by top regulator hole 18, trachea 20 and gas-tpe fitting 21.When three road gas pressures are identical, top pressure chamber 15, the pressure of spring 8A that the tubular spool 7 of every road gas is subject to, with bottom pressure chamber 16 and the pressure balance of spring 9B, it is in steady statue.When wherein a road gas pressure diminishes, on the one hand, the reduction of top pressure chamber 15 gas pressure of first via gas, cause the reduction of the bottom pressure chamber 16 of the second road gas, the tubular spool 7 of the second road gas moves to bottom, the area making spool air inlet 13 cover upper end cover air inlet 11 increases, crushing increases, make to enter into tubular spool 7 second road gas pressure to reduce, cause the reduction of the second gas tubular spool 7 top, road pressure chamber 15 gas pressure, accordingly, cause and bottom the 3rd road gas, press chamber 16 pressure to reduce, same the 3rd road Gas top pressure chamber 15 pressure that makes reduces, and then cause pressure chamber 16 pressure bottom first via gas to reduce.On the other hand, meanwhile, top (center) pressure that the tubular spool 7 of the first via is subject to reduces, tubular spool 7 is mobile to top (outside), corresponding spool air inlet 13 also moves to top, the area making spool air inlet 13 cover upper end cover air inlet 11 reduces, and cross section crushing reduces so that enters into tubular spool 7 gas pressure and increases.These two effect superpositions so that the 1st road gas pressure is rapidly reached balance, corresponding additionally two-way also reaches balance.Vice versa.Thus ensure that 3 road gas pressures are equal.
Gas ratio regulation process:
The gas that three road pressure are identical, if temperature is identical, enters into Flow-rate adjustment chamber 30 along spool venthole 14 and upper end cover cavity venthole 12.Regulation rotates regulation screw mandrel 22, screw thread on lid 27 boss of temperature compensation chamber, the rotary motion of regulation screw mandrel 22 is changed into moving axially of temperature compensation chamber lid 27, temperature compensation chamber lid 27 drives temperature compensation cavity 26 and compensation lid 33 to move forward and backward, change the orifice size covering venthole 31, obtain required unitary gas flow, thus ensure that ratio.
Gas temperature compensation process:
Proportionally adjusting the gas of flow, if inlet temperature changes, then its flow must be adjusted, the correct proportions requirement under the identical operating mode of guarantee.If a road gas temperature raises, the gas that this temperature raises enters into wind spring chamber 37, by conduction of heat and convection action by passage 31 so that bimetallic wind spring 36 temperature also raises.Owing in bimetal leaf spring 36, outside sheet metal physical expansion coefficient is different, the deflection of overall length elongation is different, the spiral bimetallic wind spring 36 of level, and fixing end is fixed on the wind spring alignment pin 35 on temperature compensation cavity 26, free end is connected with compensating lid 33, and compensating lid 33 can move forward and backward.Bimetallic wind spring 36 temperature raises, outside bimetallic wind spring 36, sheet metal is bigger than interior survey sheet metal swell increment, bimetallic wind spring 36 diameter is shortened, orders about free end and compensate lid 33 be moved rearwards by close to fixing end, drive, reduce the orifice size covering venthole 31, increasing aperture area so that after gas temperature increases, flow increases, correct the error that variations in temperature causes, it is achieved that temperature-compensating；Vice versa.
Gas mixed process:
The unitary gas of constant flow really after pressure and temperature compensates, from venthole 31 out after, along three runners 38 that 120 ° of stars are uniform, conflux in the hybrid chamber 39 at center, uniformly after mixing, export from mixed gas delivery outlet 40.
