Description
Technical field
The utility model belongs to fluid machinery research field, and in particular to a kind of multicomponent gas matches mixing arrangement.According to
The need for production, continuous mixing multicomponent gas, meets welding, electronics, combustion gas, illumination, surface treatment, medical treatment and smelts in proportion
Etc. 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 is used for the carbon steel, low-alloy steel, stainless steel for welding 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
System is completed.Air distributing method is generally divided into static volumetric method and Devince By Dynamic Gas Ration Method.Static volumetric method is a certain amount of original
Expect that gas is added in the container of known volume, then pour diluent gas, mix and be made.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
It is applied to the configuration for the calibrating gas that activity is poor and consumption is little in this way.

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 matched somebody with somebody
Compare system.
Regulation matching system, inputs gas by decompression venting valve manually, reaches regulation proportioning valve, 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 inputted using each gas single channel, computer, PLC or single-chip microcomputer control are adopted
With flowmeter and choke valve, either use flow controller or use analytical instrument feedback control choke valve, can realize
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
Intracavitary is moved along axis, changes 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.
