Abstract
The invention discloses an engine cylinder cover capable of enhancing the valve cooling effect. The engine cylinder cover comprises a cover body. The cover body is provided with an intake passage, an exhaust passage and a combustion chamber. An opening of the intake passage is provided with an intake valve pipe seat. An opening of the exhaust passage is provided with an exhaust valve pipe seat. The cover body is further provided with water sleeves and water holes for communicating the water sleeves and grooves. According to the engine cylinder cover capable of enhancing the valve cooling effect, the intake valve pipe seat and the exhaust valve pipe seat are arranged at the opening of the intake passage and the opening of the exhaust passage respectively, so that when the intake valve pipe seat and the exhaust valve pipe seat generate friction wear in work and a gap among other valve rods exceeds the designed value, the engine cylinder cover can be maintained by replacing the intake valve pipe seat and the exhaust valve pipe seat, and maintenance convenience is good; in addition, the water sleeves are communicated with the grooves through the arrangement of the water holes, cooling water in the water sleeves is directly led into the intake valve pipe seat and the exhaust valve pipe seat for cooling, and the cooling effect is good; and the problem that the strength of the cover body valve portion, the intake valve pipe seat and the exhaust valve pipe seat is lowered due to the fact that the temperature rises is solved.
Description
Technical field
The present invention relates to a kind of engine components, particularly a kind of cylinder cap of motor.
Background technique
Cylinder head is one of main parts size of motor, and major function is sealing cylinder top, and forms firing chamber with piston head together with cylinder.Cylinder head is provided with intake valve and exhaust valve, be provided with valve stem in intake valve and exhaust valve, motor in the course of the work, controls the opening and closing of intake valve and exhaust valve by valve stem, realize from intake valve inhale fresh air or combustion gas, discharge the waste gas after burning from exhaust valve.
Because motor there will be high-frequency combination and is separated between valve stem and intake valve, exhaust valve in the course of the work, this makes the intake valve of cylinder and the easy fretting wear of exhaust valve part, cause valve stem can not excellent sealing inlet and outlet door, engine efficiency is caused to reduce, but cylinder head of the prior art is monolithic construction, make the maintenance after the inlet and outlet door section fretting wear of cylinder head comparatively difficult.
And when engine operation, intake valve directly contacts with high-temperature fuel gas with exhaust valve, valve portion temperature height is very fast, temperature is higher, the rising of the intensity temperature in valve portion can reduce, poor to the Cooling Design in the valve portion of cylinder head in prior art, not can solve valve portion Yin Wendu and raise the technical problem causing intensity to reduce.
Summary of the invention
In view of this, the object of this invention is to provide a kind of engine cylinder cover that can strengthen the cooling of valve portion, to solve the technical problem of cylinder head of the prior art maintenance difficult after intake valve and exhaust valve wearing and tearing; And the valve portion of cylinder head can not can be raised the technical problem causing intensity to reduce by Yin Wendu by good cooling, valve portion in solution prior art.
The present invention can strengthen the engine cylinder cover of valve portion cooling, comprises lid, described lid is provided with intake duct, air outlet flue and firing chamber;
The oral area of described intake duct is provided with the intake valve base coordinated with valve stem, and described air outlet flue oral area is provided with the exhaust valve base coordinated with valve stem;
Described intake valve base and exhaust valve base include body and are arranged on the annular flange flange of body leading portion, the groove that the oral area of described intake duct and air outlet flue is provided with the recessed seam of the annular coordinated with annular flange flange and coordinates with body, the position that described body is connected with annular flange flange is provided with the groove of weakened annular flange and body thickness;
Described lid is also provided with water jacket and is communicated with the water hole of water jacket and groove.
Further, described body is provided with the first seal ring coordinated with groove walls, the recessed seam of described annular is provided with the second seal ring coordinated with annular flange flange.
Further, described intake valve base and exhaust valve base are straight tube structure.
Beneficial effect of the present invention:
1, the present invention can strengthen the engine cylinder cover of valve portion cooling, it is by arranging intake valve base and exhaust valve base at intake duct and air outlet flue oral area, make when intake valve base and exhaust valve base at work fretting wear occur, when causing the gap between all the other valve stems to exceed design load, mode by changing intake valve base and exhaust valve base is keeped in repair engine cylinder cover, and servicing ease is good.
2, the present invention can strengthen the engine cylinder cover of valve portion cooling, water jacket is communicated with groove by arranging water hole by it, thus the cooling water in water jacket is directly caused intake valve base and exhaust valve base cools, good cooling results, solves lid valve portion and intake valve base and exhaust valve base Yin Wendu and raises and the problem of intensity reduction.
Accompanying drawing explanation
Fig. 1 is the broken section structural representation that the present embodiment can strengthen the engine cylinder cover of valve portion cooling;
Fig. 2 is the structural representation of exhaust valve base.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment can strengthen the engine cylinder cover of valve portion cooling, comprises lid 1, described lid is provided with intake duct 2, air outlet flue 3 and firing chamber 4;
The oral area of described intake duct is provided with the intake valve base 5 coordinated with valve stem, and described air outlet flue oral area is provided with the exhaust valve base 6 coordinated with valve stem;
Described intake valve base and exhaust valve base include body 7 and are arranged on the annular flange flange 8 of body leading portion, the groove that the oral area of described intake duct and air outlet flue is provided with the recessed seam of the annular coordinated with annular flange flange and coordinates with body, the position that described body is connected with annular flange flange is provided with the groove 9 of weakened annular flange and body thickness;
Described lid is also provided with water jacket 10 and is communicated with the water hole 11 of water jacket and groove.
The present embodiment can strengthen the engine cylinder cover of valve portion cooling, it is by arranging intake valve base and exhaust valve base at intake duct and air outlet flue oral area, make when intake valve base and exhaust valve base at work fretting wear occur, when causing the gap between all the other valve stems to exceed design load, mode by changing intake valve base and exhaust valve base is keeped in repair engine cylinder cover, and servicing ease is good.
And the present embodiment can strengthen the engine cylinder cover of valve portion cooling, water jacket is communicated with groove by arranging water hole by it, thus the cooling water in water jacket is directly caused intake valve base and exhaust valve base cools, good cooling results, solves lid valve portion and intake valve base and exhaust valve base Yin Wendu and raises and the problem of intensity reduction.
As the improvement to the present embodiment, described body is provided with the first seal ring 12 coordinated with groove walls, the recessed seam of described annular being provided with the second seal ring 13 coordinated with annular flange flange, cooling water can better being stoped to enter in firing chamber by arranging seal ring.
As the improvement to the present embodiment, described intake valve base and exhaust valve base are straight tube structure, and the resistance of straight tube to air-flow is less, are conducive to the intake and exhaust efficiency improving motor.
