Abstract
The utility model discloses an exhausting valve of an engine. The guide rod of the exhausting valve of an engine is equipped with a stopping gas slice whose position mounted on the guide rod of the gas value doesn't effect the normal opening and the closing and the exhausting gas of the exhausting valve of an engine. The stopping gas slice can be integrally loaded to follow the exhausting valve of an engine from the open of the value. After the exhausting valve of engine is adopted, the hot waste gas exhausted from a cylinder is directly guided the waste gas exhausting channel of the engine by the stopping gas slice when the engine operates and no longer directly jetted into the clearance between the guide rod and the guide pipe for guiding valve of the exhausting valve of an engine to eliminate the adverse effect of the hot waste of the engine lubricating the guide rod and the guide pipe of the exhausting valve of engine so that the service lives of the exhausting valve of an engine, the valve open and the guide pipe for guiding to the valve are extended. The exhausting valve of an engine provides guarantee for the engine normally working.
Description
Technical field
The utility model relates to a kind of engine exhaust valve.
Background technique
At present, the valve guide bushing of engine exhaust valve by the guiding on its guide rod and the engine cylinder head body matches and is installed on the engine cylinder head body, between the valve guide bushing of exhaust valve guide rod and its guiding by oil lubrication.Because the end of the valve guide bushing of guiding is directly exposed on the waste gas discharge route of motor, the high-temp waste gas of being discharged in the engine cylinder injects directly on the end face of valve guide bushing of guiding, from the gap of the valve guide bushing of valve guide rod and guiding, enter and produce carbon distribution, cause lubricant oil can not be effectively the valve guide bushing of valve guide rod and guiding to be lubricated, therefore, there is insufficient lubrication in the available engine exhaust valve, serious wear, the defective that resistance increases, and the exhaust valve gas leak phenomenon is serious, cause engine performance to descend, strengthened discharge amount of exhaust gas simultaneously.
The model utility content
Defective at the existence of available engine exhaust valve, the purpose of this utility model provides a kind of motor novel exhaust valve, the high-temp waste gas that this novel exhaust valve can prevent from the engine cylinder to be discharged is directly injected in the valve guide bushing gap of guiding of exhaust valve guide rod, thereby reduces the adverse effect of institute's waste discharge gas to lubricating between the valve guide bushing of valve guide rod and its guiding in the engine cylinder.
For realizing the purpose of this utility model, this motor novel exhaust valve comprises engine exhaust valve and airtight plate, described airtight plate is fixed on the guide rod of described engine exhaust valve, and be tightly connected between airtight plate and the guide rod, the position of airtight plate on valve guide rod do not influence the normal switching and the exhaust of engine exhaust valve, and airtight plate can unload from valve port with engine exhaust valve integral body.
For realizing the purpose of this utility model, this motor novel exhaust valve comprises valve end, guide rod and airtight plate, three parts are made into integration, airtight plate is positioned on the guide rod, the position of airtight plate on valve guide rod do not influence the normal switching and the exhaust of engine exhaust valve, and airtight plate can unload from valve port with engine exhaust valve integral body.
Further, described airtight plate tilts to the engine exhaust passage direction, and its angle of inclination is corresponding with the angle at cylinder head body cavity body bottom and waste gas discharge route place.
After adopting this motor novel exhaust valve, the high-temp waste gas of discharging from cylinder during engine operation is deflated airtight plate that valve guide rod the is provided with engine exhaust discharge route that directly leads, and no longer directly be sprayed onto in the valve guide bushing gap of valve guide rod and its guiding, eliminated engine high-temperature waste gas to adverse effect lubricated between the valve guide bushing of valve guide rod and its guiding, prolonged the working life of the valve guide bushing of engine exhaust valve, valve port and guiding thereof, for the proper functioning of motor provides assurance.
Description of drawings
Fig. 1 is this motor novel exhaust valve user mode schematic representation;
Fig. 2 is the airtight plate enlarged diagram.
Embodiment
As shown in drawings, the engine exhaust valve is installed on the engine cylinder head body 1 by the valve guide bushing 8 of guiding.Airtight plate 7 is made by metal sheet, be processed with through hole 71 in the middle of it, fixing by this through hole airtight plate 7 with valve guide rod 6 welding, airtight plate 7 tilts to engine exhaust discharge route 4 directions, the angle of inclination is corresponding with the angle at cylinder head body cavity body bottom 9 and waste gas discharge route 4 places, the position of airtight plate 7 does not influence the normal switching of exhaust valve simultaneously, and does not influence the normal discharging of waste gas.Airtight plate 7 can whole unload from valve port 3 together with exhaust valve.
During work, the engine exhaust valve moves downward, valve end 5 separates with engine air doorway 3, high-temp waste gas in the cylinder discharges by cylinder head body cavity body 2, since airtight plate 7 stop that high-temperature gas directly is sprayed onto on the airtight plate 7, and no longer directly be sprayed onto the end of the valve guide bushing 8 of guiding, avoid the high-temperature gas to the lubricated adverse effect between the valve guide bushing 8 of valve guide rod 6 and guiding, eliminated the carbon distribution phenomenon in the gap of valve guide rod 6 and the valve guide bushing 8 of guiding.After airtight plate 7 is arranged to heeling condition, make high-temp waste gas be directly oriented to exhaust steam passage 4, can avoid the exhaust of motor is had a negative impact.
Claims (3)
1. motor novel exhaust valve, comprise the engine exhaust valve, it is characterized in that, also comprise airtight plate, described airtight plate is fixed on the guide rod of described engine exhaust valve, and be tightly connected between airtight plate and the guide rod, the position of airtight plate on valve guide rod do not influence the normal switching and the exhaust of engine exhaust valve, and airtight plate can unload from valve port with engine exhaust valve integral body.
2. motor novel exhaust valve, it is characterized in that, comprise valve end, valve guide rod and airtight plate, three parts are made into integration, airtight plate is positioned on the valve guide rod, the position of airtight plate on valve guide rod do not influence the normal switching and the exhaust of engine exhaust valve, and airtight plate can unload from valve port with engine exhaust valve integral body.
3. motor novel exhaust valve as claimed in claim 1 or 2 is characterized in that, described airtight plate tilts to the engine exhaust passage direction, and its angle of inclination is corresponding with the angle at cylinder head body cavity body bottom and waste gas discharge route place.
