The air inlet face of available engine firing chamber intake valve all adopts level and smooth formula structure, and the disadvantage of this structure is: can not reach the abundant mixing of inflammable gas, be unfavorable for the perfect combustion of inflammable gas and reduce fuel consume and the exhaust gas discharging pollution.
The model utility content
In view of this, the utility model provides a kind of valve, to improve the combustion efficiency of combustion gas, reduces fuel consume and exhaust gas discharging and pollutes.
For achieving the above object, the utility model provides following technological scheme:
A kind of valve comprises valve head and the engine valve stem that links to each other with this valve head, and the air inlet face of described valve head is provided with aeroscopic plate vertically, and described aeroscopic plate is a plurality of, and a plurality of described aeroscopic plates are along the circumferentially-spaced of described air inlet face.
Preferably, in above-mentioned valve, these a plurality of aeroscopic plates are spiral to be distributed on the described air inlet face.
Preferably, in above-mentioned valve, a plurality of described aeroscopic plates are distributed on the described air inlet face.
Preferably, in above-mentioned valve, the outer ring of described valve head air inlet face is provided with the sealed department adaptive with valve seat.
Preferably, in above-mentioned valve, an end of described aeroscopic plate links to each other with described engine valve stem, and the other end links to each other with described sealed department.
Preferably, in above-mentioned valve, the end that described aeroscopic plate links to each other with described engine valve stem is straight plate, and an end that links to each other with described sealed department is an arc plate.
Preferably, in above-mentioned valve, described aeroscopic plate is an arc plate.
From above-mentioned technological scheme as can be seen, the utility model has a plurality of aeroscopic plates by the air inlet face at the valve head along circumferentially-spaced, thereby can have certain leading role to inflammable gas.
In addition, if be distributed on the described air inlet face aeroscopic plate is spiral, under the guide functions of the gas guide groove that forms between adjacent two aeroscopic plates, inflammable gas is ejected in the strong eddy airstream of generation in the firing chamber along the gas guide groove high speed rotating, making inflammable gas obtain sufficient secondary mixes, the perfect combustion of inflammable gas is achieved, pollutes to reach effective reduction fuel consume and exhaust gas discharging.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
The structural scheme of mechanism of the valve that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the plan view of Fig. 1;
The structural scheme of mechanism of the valve that Fig. 3 provides for another embodiment of the utility model;
Fig. 4 is the plan view of Fig. 3.
Embodiment
The utility model provides a kind of valve, to improve the combustion efficiency of inflammable gas, reduces fuel consume and exhaust gas discharging and pollutes.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 1-Fig. 4, the structural scheme of mechanism of the valve that Fig. 1 provides for the utility model embodiment; Fig. 2 is the plan view of Fig. 1; The structural scheme of mechanism of the valve that Fig. 3 provides for another embodiment of the utility model; Fig. 4 is the plan view of Fig. 3.
The valve 1 that the utility model provides, comprise valve head and the engine valve stem that links to each other with this valve head, the air inlet face of valve head is provided with aeroscopic plate 11 vertically, and described aeroscopic plate 11 is a plurality of, and a plurality of described aeroscopic plates 11 are along the circumferentially-spaced of described air inlet face.Concrete, these a plurality of described aeroscopic plates 11 can be distributed on the described air inlet face.Two adjacent aeroscopic plates 11 form gas guide groove 12, and gas guide groove 12 has the air guide effect, the inflammable gas of outside can be imported inside, firing chamber rapidly.
The utility model has a plurality of aeroscopic plates 11 by the air inlet face at the valve head along circumferentially-spaced, thereby can have certain leading role to inflammable gas, thereby can make and when valve 1 is opened, produce strong eddy airstream, thereby inflammable gas is fully mixed, with perfect combustion that reaches combustion gas and the purpose that reduces fuel consume and exhaust emission pollution.
Further in order to optimize technique scheme, a plurality of aeroscopic plate 11 preferred spiral being distributed on the described air inlet face (can also can be backpitch as shown in Figure 4 for by right-handed screw shown in Figure 2).Under the guide functions of the gas guide groove 12 that forms between adjacent two aeroscopic plates 11, inflammable gas is ejected in the strong eddy airstream of generation in the firing chamber along gas guide groove 12 high speed rotating, making inflammable gas obtain sufficient secondary mixes, the perfect combustion of inflammable gas is achieved, pollutes to reach effective reduction fuel consume and exhaust gas discharging.
