Pressure compensation process：
When ternary gas enter in tubular valve element 7 from upper end cover air admission hole 11 and valve element air admission hole 13 respectively, in tubular valve
Shunting is realized in core 7, most of gas enters valve element venthole 14, and the gas of fraction enters top pressure chamber by pressure stable hole 17
Room 15, the bottom regulator hole 19 of another first gas is then connected to by top regulator hole 18, gas circuit 20 and gas path joint 21.When
When three road gas pressures are identical, chamber 15, spring 8A pressure are pressed in the top being subject to per the tubular valve element 7 of road gas, with bottom
Chamber 16 and spring 9B pressure balance are pressed, in stable state.When wherein gas pressure becomes small all the way, on the one hand, first
The reduction of the top pressure gas pressure of chamber 15 of road gas, causes the bottom of the second road gas to press the reduction of chamber 16, the second tunnel
The tubular valve element 7 of gas moves to bottom so that valve element air admission hole 13 covers the area increase of upper end cover air admission hole 11, and crushing increases
Greatly so that enter the road gas pressure of tubular valve element 7 second and reduce, cause the top of the second road gas tubular valve element 7 pressure chamber 15
The reduction of gas pressure, accordingly, the 3rd road gas bottom pressure chamber 16 pressure is caused to reduce, same causes the 3rd road gas
Top pressure chamber 15 pressure reduces, and then causes first via gas bottom pressure chamber 16 pressure to reduce.On the other hand, it is same with this
When, top that the tubular valve element 7 of the first via is subject to（Center）Pressure reduces, and tubular valve element 7 is to top（It is outside）It is mobile, accordingly
Valve element air admission hole 13 also moves to top so that the area that valve element air admission hole 13 covers upper end cover air admission hole 11 reduces, section pressure
Damage is reduced so that enters the increase of the gas pressure of tubular valve element 7.This two effect superpositions so that the 1st road gas pressure reaches rapidly
To balance, corresponding two-way in addition also reaches balance.Vice versa.So as to ensure that 3 road gas pressures are equal.
Gas ratio adjusts process：
Three tunnel pressure identical gases, if temperature is identical, enter along valve element venthole 14 and upper end cover cavity venthole 12
Enter to Flow-rate adjustment chamber 30.Regulation, which rotates, adjusts screw mandrel 22, the screw thread on the boss of temperature compensation chamber lid 27, will adjust the rotation of screw mandrel 22
Motion is changed into the axial movement of temperature compensation chamber lid 27, and temperature compensation chamber lid 27 drives temperature compensation cavity 26 and compensation lid 33 movable, changed
Become the orifice size of covering venthole 31, required unitary gas flow is obtained, so as to ensure that ratio.
Gas temperature compensation process：
The gas of flow is proportionally adjusted, if inlet temperature changes, its flow must be adjusted,
It can guarantee that the correct proportions requirement under identical operating mode.If gas temperature raises all the way, the elevated gas of this temperature passes through ventilation
Hole 31 enters wind spring chamber 37, passes through heat transfer and convection action so that the temperature of bimetallic wind spring 36 also raises.Due to bimetallic
Outside sheet metal physical expansion coefficient is different in flat spring 36, and the deflection of overall length elongation is different, the double gold of horizontal spiral shape
Belong to wind spring 36, fixing end is fixed on the wind spring alignment pin 35 on temperature compensation cavity 26, and free end is connected with compensation lid 33, compensation lid
33 can move forward and backward.The temperature of bimetallic wind spring 36 raises, and the outside sheet metal of bimetallic wind spring 36 is than interior survey sheet metal swell increment
Greatly so that the diameter of bimetallic wind spring 36 shortens, and drives free end to drive compensation lid 33 to be moved rearwards close to fixing end, reduce
The orifice size of venthole 31 is covered, increases aperture area so that after gas temperature increase, flow increase, corrects temperature
Error caused by degree change, realizes temperature-compensating；Vice versa.
Gas mixing process：
The unitary gas of constant flow really after pressure and temperature compensates, after venthole 31 comes out, along 120 ° of stars
Three uniform runners 38, conflux in the hybrid chamber 39 at center, uniformly after mixing, exported from mixed gas delivery outlet 40.
The embodiment is preferred embodiment of the invention, but the present invention is not limited to above-mentioned embodiment, not
Away from the present invention substantive content in the case of, those skilled in the art can make it is any it is conspicuously improved, replace
Or modification belongs to protection scope of the present invention.
