Description
Technical field
The invention belongs to fluid machinery research field, and in particular to a kind of multicomponent gas match mixing arrangement.According to production
The need for, continuous mixing multicomponent gas, meet the rows such as welding, electronics, combustion gas, illumination, surface treatment, medical treatment and smelting in proportion
The specific demand of industry.
Background technology
With the development of science and technology, the industry such as welding, electronics, illumination, medical treatment, surface treatment and smelting is wanted to protection gas
Ask, by past pure gas, change into using the Diversity gas matched according to different proportion, can reach preferably
Effect.Such as gas shielded arc welding, binary gas Ar+75%He be widely used in thickness 25mm above aluminium prosposition put automatic welding,
Ar+ (5%~10%) CO2+ (1%~3%) O2Mixed gas are used to weld carbon steel, low-alloy steel, the stainless steel of various thickness；
Gaseous mixture (11%) C2H4O+ (53%) CCl3F+ (36%) CCl2F2Medical industry is widely used in, carry out disinfection sterilization；Gaseous mixture
Ar+ (0.1~1.0%) CH3Br+ (5~80%) Kr is used for illuminating device, etc..
Hybrid protection gas is mixed to scale by 2 kinds and above gas, and gas proportion mixing is by distribution

Material gas is added in the container of known volume, then pours diluent gas, is mixed and is obtained.The advantage of this distribution method is equipment letter
Single, operation is easy, but because some gas chemistries are more active, contacted with chamber wall to chemically react for a long time, institute
In this way it is applied to the configuration of the calibrating gas that activity is poor and consumption is little.
Calibrating gas is typically to provide the bottled gas for mixing to scale according to static volumetric method by supplying business, by
Can not meet the demand of continuous, a large amount of use gas in bottled gas, mixed proportion can not Field adjustment, in addition bottled gas have one
The fixed term of validity, this is just to using bringing inconvenience.
Thus dynamic gas mixer has obtained more being widely applied.Dynamic gas mixer prepares gas velocity soon, distribution
Ratio can be continuously adjusted, tolerance can with the need depending on.Current dynamic gas mixer is divided into automatically adjusting and adjusting manually and matches somebody with somebody
Compare system.
Regulation matching system, is input into gas by decompression venting valve manually, reaches regulation proportioning valve, and mix ratio is adjusted manually
Example, the system can not realize that pressure and temperature is compensated, and precision is relatively low but cheap, is mainly used in the proportioning of binary gas.
Automatically adjust matching system and application is typically input into using each gas single channel, computer, PLC or Single-chip Controlling are adopted
With flowmeter and choke valve, or flow controller is used, or use analytical instrument feedback control choke valve, can realized
Pressure and temperature is compensated, and precision is higher, and ratio is accurate, but proportioning mixing is separated, more with valve, expensive, is mainly used in many
First gas mixing ratio.
United States Patent (USP) US5095950A is mainly using a piston-type slide valve, control flow and fluid proportioning.Guiding valve exists
Moved along axis in chamber, change the size of flow.Rotary-piston guiding valve can change the proportioning of fluid.But two-spot fluid can only be entered
Row proportioning mixing.

3, the pressure and temperature of gas operating mode is input into according to three tunnels, converted, so that it is determined that valve element input air vent openings area.Assuming that
Three tunnel gas openings areas compare Ar:CO2:He=11.1:5.9:3.1.PLC outputs signal to motor 31, drives respectively flat
The weighing apparatus whole worm screw 13 of controlled atmosphere and carrier gas adjustment worm screw 18；Balance Air adjusts worm screw 13 and adjusts worm gear 17 with dynamic balancing by Balance Air
The spin balancing gas valve core 5 of controlled atmosphere bearing 12 is slided in Balance Air valve element chute 8；Carrier gas adjusts worm screw 18 by diluting controlled atmosphere
Whole worm gear 14 drives the carrier gas adjustment revolving dilution gas valve core 1 of axle 19 to be slided in dilution gas valve core chute 4.
Dilution gas valve core 1 is slided so that valve element input stomata B9 apertures are 65.556%, and valve element input stomata A2 apertures are
34.444%, its ratio is 1.903.Balance Air valve element 5 is slided so that Balance Air valve element input stomata 6 aperture is 54.815%
So as to ensure mark condition under ratio Ar:CO2:He=11:6:3.
Three road gases are penetrated through valve element input stomata A2, Balance Air valve element input stomata 6, valve element input stomata B9 in 120 °
Enter valve body, in Central Collisions, be well mixed, export the homogeneous mixture of proportioning to gas outlet tube 33 by end cap output stomata 22.
Gas access ball valve 24 is input into all the way by closing, you can realize the proportioning mixing of two-spot gas.If turned off flat
Weighing apparatus gas Inlet ball valve, is capable of achieving the output of binary mixture big flow.If turned off carrier gas Inlet ball valve, it is capable of achieving binary and mixes
Gas is closed to be exported compared with low discharge.
Realize that the mechanism that ternary gas mix is：
Revolving dilution gas valve core 1, adjusts valve element input stomata A2 and valve element input stomata B9 is input into stomata with valve body first
The overlapping area of A3 and valve body input stomata B, gas access area increase all the way, another proportional reduction of road inlet area reaches
To the proportion requirement of two-spot diluent gas.After the adjustment of two-spot diluent gas ratio is finished, then the ratio for adjusting Balance Air.According to
Ternary gas proportion requirement, spin balancing gas valve core 5, adjustment Balance Air valve element is input into the inlet area of stomata 6, reaches requirement ratio
Example.Realize ternary gas mixture in proportion.
Realize that the mechanism that binary gas mix is：
First, spin balancing gas valve core 5, closes Balance Air valve element input stomata 6.Then revolving dilution gas valve core 1, continuously
The aperture of adjustment valve element input stomata A2 and valve element input stomata B9, obtains any ratio of two-spot gas；Second, carrier gas one
Road does not supply, and such as valve element input stomata A2 can change Balance Air valve element without input, spin balancing gas valve core 5 and dilution gas valve core 1
The opening ratios of input stomata 6 and valve element input stomata B9, so as to adjust two-spot gas ratio.
