Description
Technical field
The present invention relates to the gas engine field, particularly a kind of engine agitator.
Background technique
Gas engine on the market mainly adopts the premixed combustion mode now, and promptly rock gas and air mix outside cylinder, forms inflammable gas, gets into cylinder at last again, carries out work by combustion.Since be the premixed combustion mode, so mixer apparatus will be arranged.Present mixer mainly contains two kinds: a kind of is the venturi type mixer, and another kind is the proportion expression mixer.The venturi type mixer is installed in spool on the diaphragm, and the motion of diaphragm drives the motion of spool, and inflammable gas mixes at the valve port place of diaphragm with air.What the proportion expression mixer adopted is the mode of directly mixing, and promptly rock gas directly gets into to mix in the body and mixes with air.
The complex structure of venturi type mixer, processing technology and to process conforming requirement very high is made difficulty, and cost is high.The proportion expression mixer structure is simple, and cost is lower, all large batch of Market for refitting that are applied in domestic second, third line city.But because it is simple in structure; The mixed effect of inflammable gas is bad, and particularly in accelerating process, the control of the concentration of inflammable gas is unstable; Directly cause the engine acceleration can be poor, serious just directly cause engine piston to melt top, suction tude seriously mechanical failure such as bursting.
Summary of the invention
The technical problem that the present invention solves provides a kind of simple in structure, the engine agitator of good mixing effect.
For achieving the above object; The invention provides a kind of engine agitator; Comprise: air inlet and mixed gas outlet that valve body and tubulose spool, valve body have mixing chamber and be positioned at the mixing chamber two ends, the inwall upper edge of mixing chamber circumferentially offer ring-type rock gas air inlet duct and by the outward extending rock gas suction port of ring-type rock gas air inlet duct; The sidewall upper edge of tubulose spool circumferentially offers a plurality of rock gas inlet holes; The tubular valve core retainer plate is contained in the mixing chamber, and the sidewall of this spool is resisted against the place, outer of ring-type rock gas air inlet duct, and rock gas gets into ring-type rock gas air inlet duct through the rock gas suction port; Spurt into the inner chamber of spool again through a plurality of rock gas inlet holes, in the inner chamber of spool with the air mixing that gets into through air inlet after mixed gas outlet gets into engine chamber.
Further, a plurality of rock gas inlet holes are evenly distributed on making progress in sidewall week of tubulose spool.
Further, offer the mounting groove that the tubulose spool is installed in the mixing chamber, tubulose spool and mounting groove interference fit are installed.
Further, the rock gas suction port has along the outward extending tubular sidewall of the sidewall of valve body, and the port of tubular sidewall is equipped with rock gas suction tude joint.
Further, the connecting end of rock gas suction tude joint and rock gas suction tude has the ring packing convexity that a plurality of edges circumferentially distribute.
Further, air inlet and mixed gas outlet are respectively arranged with adpting flange.
According to technological scheme of the present invention, owing in valve body, increased spool, make a plurality of inlet holes that rock gas passes through spool by multi-direction entering mixing chamber and air mixing, mixed effect is better.

Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention does not receive the restriction of embodiment.
Fig. 1, Fig. 2 and Fig. 3 show a preferred embodiment of the present invention; Referring to Fig. 1, Fig. 2 and Fig. 3; This engine agitator comprises: valve body 1 and tubulose spool 3; Air inlet 12 and mixed gas outlet 13 that valve body 1 has mixing chamber 11 and is positioned at mixing chamber 11 two ends, the inwall upper edge of mixing chamber 11 circumferentially offers ring-type rock gas air inlet duct 14 and by ring-type rock gas air inlet duct 14 outward extending rock gas suction ports 15, the sidewall upper edge of tubulose spool 3 circumferentially offers a plurality of rock gas inlet holes 16; Preferably, a plurality of rock gas inlet holes 16 are evenly distributed on making progress in sidewall week of tubulose spool 3.Offer mounting groove, the two ends of this tubulose spool 3 and this mounting groove interference fit suit that tubulose spool 3 is installed in the mixing chamber 11 of valve body 1.Rock gas suction port 15 has along the outward extending tubular sidewall 151 of the sidewall of valve body 1, and the port of tubular sidewall 151 is equipped with rock gas suction tude joint 152.Rock gas suction tude joint 152 is screwed on the port of this tubular sidewall 151.Rock gas suction tude joint 152 has the ring packing convexity 153 that a plurality of edges circumferentially distribute with the connecting end of rock gas suction tude, and ring packing protruding 153 can effectively guarantee the sealing of natural gas supply.
In addition; Air inlet 12 is respectively arranged with adpting flange 121 and adpting flange 131 with mixed gas outlet 13; Adpting flange 121 circumferentially offers a plurality of through holes in the edge respectively with adpting flange 131; Be connected with the pipeline that mixed gas outlet 13 links to each other with air inlet 12 through bolt, be provided with sealing gasket between adpting flange and this pipeline and guarantee sealing.
As shown in Figure 2; Air directly gets into mixing chamber 11 by air inlet 12; And rock gas gets into ring-type rock gas air inlet duct 14 through rock gas suction tude joint 152 and rock gas suction port 15 successively; Spurt into mixing chamber 11 respectively by a plurality of rock gas inlet holes 16 on tubulose spool 3 sidewalls again and form inflammable gas with air mixing, this inflammable gas carries out work by combustion by the cylinder that mixed gas outlet 13 gets into motor again.Because rock gas is spurted into mixing chamber 11 and air mixing from different directions by a plurality of rock gas inlet holes 16, make rock gas and even air mix good mixing effect.
More than disclosedly be merely a specific embodiment of the present invention, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
