Mirror, with this, the utility model proposes the gas mixer that a kind of structure is simple, avoid gas and vapor permeation flow blind angle, mix.
The technical solution of the utility model is achieved in that
A kind of gas mixer, comprise air inlet, gas mixer chamber and gas outlet, described air inlet comprises the first air inlet and the second gas air inlet, and described gas and vapor permeation indoor are provided with orifice plate.
Further, described orifice plate comprises the first orifice plate near described air inlet and/or the second orifice plate near described gas outlet.
Further, the pore of described first orifice plate and/or the second orifice plate is the combination of straight hole, inclined hole or straight hole and inclined hole.
Further, on described first orifice plate and/or the second orifice plate, the pore near described gas mixer chamber locular wall is inclined hole, and the pore near described gas mixer chamber medium position is straight hole, and the pore being positioned at described gas mixer chamber medium position is inclined hole.
Further, the pore of described first orifice plate and/or the second orifice plate is the combination of rectangular opening, circular port or rectangular opening and circular port.
Further, on described first orifice plate and/or the second orifice plate, the pore near described gas mixer chamber locular wall is rectangular opening, and the pore near described gas mixer chamber medium position is circular port, and the pore being positioned at described gas mixer chamber medium position is circular port.
Further, described air inlet and described gas outlet are provided with internal thread or external screw thread.
Compared with prior art, the beneficial effects of the utility model are:
The utility model proposes a kind of gas mixer, gas and vapor permeation indoor are provided with orifice plate, through the mixed uniformly mist that gas mixer of the present utility model obtains, the setting of pore structure makes mixed airflow enter gas mixer chamber with vorticity and exports gas mixer chamber with vorticity, avoid gas and vapor permeation flow blind angle, and obtain more full and uniform mist.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only preferred embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

In figure, 1 is air inlet, and 11 is the first air inlet, and 12 is the second air admission hole, and 2 is gas mixer chamber, and 21 is orifice plate, and 211 is the first orifice plate, and 212 is the second orifice plate, and 20 is pore, and 201 is inclined hole, and 202 is straight hole, and 3 is gas outlet.
Detailed description of the invention
In order to better understand the utility model technology contents, a specific embodiment being provided below, and by reference to the accompanying drawings the utility model being described further.
See Fig. 1 to Fig. 4, a kind of gas mixer of the utility model, comprise air inlet 1, gas mixer chamber 2 and gas outlet 3, described air inlet 1 comprises the first air inlet 11 and the second gas air inlet 12, orifice plate 21 is provided with in described gas mixer chamber 2, wherein, described orifice plate 21 comprises the first orifice plate 211 near air inlet 1 and the second orifice plate 212 near gas outlet 3, and described first orifice plate 211 and the second orifice plate 212 are provided with multiple pore 20.
First gas enters gas mixer chamber 2 from the first air inlet 11, second gas enters gas mixer chamber 2 from the second air inlet 12, first gas and the second gas are subject to the resistance from the first orifice plate 211 in the process of advancing, buffering reduces the air-flow velocity of the first gas and the second gas and makes it reach identical flow velocity to enter gas mixer chamber 2, first gas and the second gas are subject to again the resistance from the second orifice plate 212 before output after fully mixing in gas mixer chamber 2, buffering reduces the mixed airflow flow velocity of the first gas and the second gas, increase the time that the first gas and the second gas mix in gas mixer chamber 2, first gas and the second gas are fully mixed further.During actual use, the first gas is combustion gas, and the second gas is air, and the mixed uniformly mist obtained through gas mixer of the present utility model burns more abundant, realizes the beneficial effect saving the energy and protection of the environment.
Can find out from Fig. 3 and 4, in the present embodiment, described first orifice plate 211 and the second orifice plate 212, pore 20 near gas mixer chamber 2 locular wall is the rectangle inclined hole 201 that area is larger, pore 20 near gas mixer chamber 2 medium position is circular straight hole 202, and the pore 20 being positioned at gas mixer chamber 2 medium position is round taper hole 201.First orifice plate 211 is identical with pore 20 structure distribution of the second orifice plate 212.During use, first gas and the second gas obtain Vorticose air-flow through the first orifice plate 211 and enter in gas mixer chamber 2, first gas and the second gas obtain Vorticose air-flow through the second orifice plate 212 after fully mixing in gas mixer chamber 2 and export, the design of the pore 20 of the utility model gas mixer obtains the air-flow of vorticity, avoid gas and vapor permeation flow blind angle, obtain the more uniform mist of mixing.
In addition, air inlet 1 and the gas outlet 3 of the gas mixer of the present embodiment are equipped with internal thread or external screw thread, are conveniently connected with gas delivery conduit.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
