Description
Technical field
The utility model relates to a kind of air outlet duct system of surfboard vent systems, particularly a kind of surfboard engine.
Background technique
Conventionally, what enmgine exhaust adopted is that vermicular cast iron or high nickel cast iron cast inblock form, and what also the motor of some adopted is that individual layer stainless-steel pipe is welded.Due to Modern Engine excessive discharge temperature, general motor adopts thermal shield that the delivery temperature of motor and part are around separated by, prevent that delivery temperature is by burned other objects and lost efficacy: and for the exhaust noise of motor, be all generally the noise that adds former and later two bafflers and reduce vent systems on car load.
In motor when operation,, the high-temperature gas of discharging after burning is from engine cylinder cover to exhaust elbow, then from exhaust elbow to silencing apparatus, then exhaust is directly discharged to rivers or marine greatly.
Because the shell of surfboard is to be all generally made by resin, serviceability temperature can not exceed 150 DEG C, otherwise, shell is understood deliquescing and is caused the damage of surfboard hull not move, be speed and acceleration and surfboard engine when operation needs, require motor to reach in a short period of time higher rotating speed.Therefore, the normal applying working condition of surfboard engine is more than 4000rpm, reach as high as 6000rpm, the delivery temperature of motor is generally more than 750 DEG C, the highest even up to 860 DEG C, like this, surfboard Once you begin moves, motor can distribute a large amount of heats at short notice, temperature in engine nacelle is raise rapidly, if can not as early as possible heat be shed and make soon the peripheral element of motor lose efficacy, the housing deliquescing of surfboard and lose driving functions, and can cause fire, cause serious consequence.
Surfboard, when at overwater service, because the foreign material such as silt pasture and water stop up exhaust elbow inlet pipeline, can not guarantee that exhaust elbow has water quench.If motor exceedes 30 seconds working time, motor can distribute a large amount of heats at short notice, temperature in engine nacelle is raise rapidly, if can not as early as possible heat be shed and make soon the peripheral element of motor lose efficacy, the housing deliquescing of surfboard and lose driving functions, and can cause fire, cause serious consequence.
China Patent No. is that the patent documentation of CN02107833.5 discloses a kind of inside and outside two-layer outlet pipe, the patented technology that this type of is relevant and documents and materials all do not relate to Double water-cooled and noise reduction technology, therefore, existing known technology use surfboard such easily fast produce high temperature, again to the temperature strict occasion that raises, be difficult to meet the demands.
Model utility content
Its object of the utility model is just to provide a kind of surfboard vent systems, has the less feature of component that engine exhaust stroke is short, simple in structure, medium tache is few, use, and has reduced the noise of vent systems, has improved the travelling comfort of driving.Guarantee the reliability of water quench.
The technological scheme that realizes above-mentioned purpose and take, comprise the exhaust elbow being connected on exhaust flange, described exhaust elbow is double layer construction, between internal and external layer body, form water cavity, described water cavity is positioned at exhaust flange one end and is provided with water intake, and the described exhaust elbow the other end is connected with silencing apparatus through silencing apparatus stuffing box gland suitable for reading, and the silencing apparatus the other end is connected with exhaust elbow through silencing apparatus connecting tube, described silencing apparatus is provided with steam joint, and steam joint is connected with exhaust gum cover through steam connecting tube.
Compared with prior art the utlity model has following advantage.
1, on silencing apparatus, weld steam joint, be connected with exhaust gum cover by steam connecting tube, the cooling steam of fraction exhaust elbow is discharged outside ship, to check at any time by exhaust gum cover;
2, adopt the double-deck extrusion pressing type aluminium of hollow, centre utilizes flowing of seawater or river that outlet pipe is cooling, can effectively reduce the exhaust elbow temperature of surfboard engine, cancel the thermal shield of conventional engines, reduce temperature in engine compartment, make engine exhaust bend pipe surface temperature be no more than 50 °, reduce temperature in engine compartment, make the exhaust elbow part around amount of heat that especially rubber parts and working of plastics can not send because of exhaust elbow and lost efficacy;
3, the gas that utilizes the cooling water of exhaust elbow to discharge exhaust elbow carries out secondary noise reduction, reduces the noise of vent systems, improves the travelling comfort of driving;
4, adopt cooling water to check mechanism, guarantee the reliability of water quench.
