Abstract
The invention discloses a kind of spiral-flow type air mixers, including housing, nozzle, fin, combustion gas take over, end cap and sensor, the end cap is connected by bolt two with housing, the combustion gas is taken over through the flanged joint on bolt one and end cap, the combustion gas is taken over sets O-ring to seal between end cap, and sensor is mounted on housing；Fin is provided in the housing, combustion gas is taken over through combustion gas, nozzle enters in mixer case, and air enters by fin in housing to be mixed with combustion gas.The present invention adds fin in mixer case, thus it is possible to vary air-flow direction realizes air swirl, substantially increases the mixed effect with combustion gas, improves engine combustion and then reduces discharge, environmental protection；The present invention can reduce length of pipe, connecting line is more flexible, and versatility improves, and reduces management and use cost, while makes complete machine arrangement more compact, beautiful using six hole flange form designs.
Description
Technical field
The present invention relates to a kind of engine fuel gas mixers, belong to technical field of automobile engine.
Background technology
Mixer mixes the two generally by nozzle for spray formula gas engine air and combustion gas mixing, existing mixer in advance
It closes, in the case where space is limited, mixed effect may be bad.In addition, generally mixing with device end cap has used hoop connector, direction is solid
Fixed, which limits the trend of pipeline, versatility is poor.
The content of the invention
The technical problems to be solved by the invention are in view of the defects existing in the prior art, it is tighter to provide a kind of complete machine arrangement
Gather spiral-flow type air mixer.
To solve this technical problem, the present invention provides a kind of spiral-flow type air mixer, including housing, nozzle, wing
Piece, combustion gas are taken over, end cap and sensor, the end cap are connected by bolt two with housing, and the combustion gas is taken over through bolt one
With the flanged joint on end cap, the combustion gas is taken over sets O-ring to seal between end cap, and sensor is mounted on housing；Institute
It states and fin is provided in housing, combustion gas is taken over through combustion gas, nozzle enters in mixer case, and air enters by fin in housing
It is mixed with combustion gas.
The end cap upper flange is six hole flanges, and combustion gas is taken over to be connected by bolt with wherein holes on six hole flanges.
Advantageous effect：The present invention adds fin in mixer case, thus it is possible to vary air-flow direction realizes air rotation
Stream substantially increases the mixed effect with combustion gas, improves engine combustion and then reduces discharge, environmental protection；The present invention uses
Six hole flange forms designs, can reduce length of pipe, and connecting line is more flexible, and versatility improves, reduce management and use into
This, while make complete machine arrangement more compact, it is beautiful.
Description of the drawings
Fig. 1 is side view axis side schematic diagram of the present invention；
Fig. 2 overlooks axis side schematic diagram for the present invention；
Fig. 3 is assembling schematic diagram of the present invention；
Fig. 4 is schematic cross-sectional view of the present invention.
In figure：1 housing, 2 nozzles, 3 fins, 4 combustion gas are taken over, 5 bolts one, 6 bolts two, 7 end caps, 8 sensors, 9 O-shaped
Circle.
Specific embodiment
The present invention is specifically described with reference to the accompanying drawings and embodiments.
Fig. 1 show side view axis side schematic diagram of the present invention.
Fig. 2 show the present invention and overlooks axis side schematic diagram.
The present invention includes housing 1, nozzle 2, fin 3, combustion gas take over 4, end cap 7 and sensor 8.
Fig. 3 show assembling schematic diagram of the present invention.
Housing 1 is mixer main part, and nozzle 2 is arranged in housing 1.
The end cap 7 is connected by bolt 26 with housing 1, and the combustion gas take over 4 passes through the method on bolt 1 and end cap 7
Orchid connection, sets O-ring 9 to seal between the combustion gas take over 4 and end cap 7.
7 upper flange of end cap is six hole flanges, and combustion gas take over 4 is connected by bolt 5 with wherein holes on six hole flanges,
Can select mounting hole according to actual needs, improve generally mix with device air inlet end cap direction fix, poor universality the problem of.
The sensor 8 is mounted on housing 1, for detecting pressure.
3 cyclone structure of fin is provided in the housing 1, improves mixed effect, solution generally mixes with device in the confined space
The problem of mixed effect is insufficient.
Fig. 4 show schematic cross-sectional view of the present invention.
Combustion gas enters through combustion gas take over 4, nozzle 2 in mixer case 1, and air enters by fin 3 in housing 1 and combustion gas
It is mixed, fin 3 can generate flow-disturbing to air, and air is made to carry out spiral-flow type with combustion gas and is mixed, to reach in smaller sky
It is interior to generate better mixed effect.
The present invention adds fin in mixer case, thus it is possible to vary air-flow direction is realized air swirl, carried significantly
The high mixed effect with combustion gas, improves engine combustion and then reduces discharge, environmental protection；The present invention uses six hole flange forms
Design, can reduce length of pipe, and connecting line is more flexible, and versatility improves, and reduce management and use cost, while make whole
Machine arrangement is more compact, beautiful.
The embodiment above of the present invention, is merely illustrative, be not it is only, it is all within the scope of the present invention or it is equivalent this
Change in the range of invention is surrounded by the present invention.
