Description
Technical field
The utility model relates to a kind of gas mixer, refers more particularly to three kinds of gas uniform mixing arrangements.
Background technology
At present, in the middle of the laboratory of chemical industry, often run into the problem of testing after three kinds of gas with various are evenly mixed, owing to also not having three kinds of gas with various to carry out mixed uniformly device in the middle of laboratory, so just occur that gas mixes inhomogeneous situation unavoidably, cause experiment to occur deviation or error, have influence on the practical property of experiment, therefore, three kinds of mixed uniformly devices of gas with various are needed badly and are resolved.
Utility model content
The utility model is in order to solve weak point of the prior art, and three kinds of gas uniform mixing arrangements of a kind of simple in structure, convenient operation, good mixing effect are provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: three kinds of gas uniform mixing arrangements, comprise that inside has the housing of cavity, in housing, be provided with the first orifice plate, the second orifice plate and the 3rd orifice plate, the first orifice plate and the second orifice plate be arranged in parallel, the 3rd orifice plate, between the first orifice plate and the second orifice plate, is evenly provided with respectively three above pores on the first orifice plate, the second orifice plate and the 3rd orifice plate; The first orifice plate, the second orifice plate and the 3rd orifice plate are divided into the first inlet plenum, the second inlet plenum, the 3rd inlet plenum and mixed air vessel by the cavity in housing, and mixed air vessel is surrounded and formed by the first orifice plate, the second orifice plate and the 3rd orifice plate;
Housing is provided with the first air inlet pipe being communicated with the first inlet plenum, the second air inlet pipe being communicated with the second inlet plenum, the 3rd air inlet pipe being communicated with the 3rd inlet plenum and the gaseous mixture escape pipe being communicated with mixed air vessel outward, in the first air inlet pipe, the second air inlet pipe and the 3rd air inlet pipe, is respectively equipped with a gas flow regulating valve.
All pores on described the first orifice plate and the second orifice plate are all crisscross arranged.
Described gaseous mixture escape pipe is provided with Pressure gauge.
Adopt technique scheme, the first gas enters into the first inlet plenum by the first air inlet pipe, and the second gas enters into the second inlet plenum by the second air inlet pipe, and the third gas enters into the 3rd inlet plenum by the 3rd air inlet pipe; The first gas in the first inlet plenum enters into mixed air vessel by the pore on the first orifice plate, the second gas in the second inlet plenum enters into mixed air vessel by the pore on the second orifice plate, and the third gas in the 3rd inlet plenum enters into mixed air vessel by the pore on the 3rd orifice plate.After three kinds of gases fully mix in mixed air vessel, last mist is discharged by gaseous mixture escape pipe.
Electric control gear is controlled the open degree of three gas flow regulating valves, and the volume ratio that three kinds of gases are required respectively according to the rules mixes.All pores on the first orifice plate and the second orifice plate are all crisscross arranged, and the resistance in the time of can reducing the first gas and the second gas and enter mixed air vessel in mixed air vessel both sides by orifice plate finally makes three kinds of gases obtain better, mix more equably.Pressure gauge plays the effect of monitoring gaseous mixture escape pipe and mixed air vessel's pressure, thereby guarantees the safety work of mixing arrangement.
The utility model is reasonable in design, simple in structure, safe and reliable, is specially adapted for the even mixing of three kinds of gas with various, easy operating, and good mixing effect, practical, be easy to apply.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, three kinds of gas uniform mixing arrangements of the present utility model, comprise that inside has the housing 1 of cavity, in housing 1, be provided with the first orifice plate 2, the second orifice plate 3 and the 3rd orifice plate 4, the first orifice plate 2 and the second orifice plate 3 be arranged in parallel, the 3rd orifice plate 4, between the first orifice plate 2 and the second orifice plate 3, is evenly provided with respectively three above pores 5 on the first orifice plate 2, the second orifice plate 3 and the 3rd orifice plate 4; The first orifice plate 2, the second orifice plate 3 and the 3rd orifice plate 4 are divided into the first inlet plenum 6, the second inlet plenum 7, the 3rd inlet plenum 8 and mixed air vessel 9 by the cavity in housing 1, and mixed air vessel 9 is surrounded and formed by the first orifice plate 2, the second orifice plate 3 and the 3rd orifice plate 4;
