Abstract
The invention discloses a wearproof engine cylinder cover which comprises a cover body. The cover body comprises an intake passage and an exhaust passage. An opening of the intake passage is provided with an intake valve pipe seat matched with a valve rod. An opening of the exhaust passage is provided with an exhaust valve pipe seat matched with the valve rod. According to the wearproof engine cylinder cover, 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.
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.
Summary of the invention
In view of this, the object of this invention is to provide a kind of wear-resisting type engine cylinder cover, to solve the technical problem of cylinder head of the prior art maintenance difficult after intake valve and exhaust valve wearing and tearing.
Wear-resisting type engine cylinder cover of the present invention, comprises lid, described lid is provided with intake duct and air outlet flue, and 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.
Further, described intake valve base and exhaust valve base comprise 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.
Further, described intake valve base and exhaust valve base are straight tube structure.
Beneficial effect of the present invention:
Wear-resisting type engine cylinder cover of the present invention, 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.
Accompanying drawing explanation
Fig. 1 is the broken section structural representation of the present embodiment wear-resisting type engine cylinder cover;
Fig. 2 is the structural representation of intake valve base.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment wear-resisting type engine cylinder cover, comprises lid 1, described lid is provided with intake duct 2 and air outlet flue 3, the oral area of described intake duct is provided with the intake valve base 4 coordinated with valve stem, and described air outlet flue oral area is provided with the exhaust valve base 5 coordinated with valve stem.
The present embodiment wear-resisting type engine cylinder cover, 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.
As the improvement to the present embodiment, described intake valve base and exhaust valve base comprise body 6 and are arranged on the annular flange flange 7 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 8 of weakened annular flange and body thickness.When valve stem 9 is in the process of closing valve; valve stem and produce larger impact force between intake valve base and exhaust valve base; this improvement makes annular flange flange and body have certain elasticity; thus can cushion impact force; be conducive to protection intake valve base and exhaust valve base, avoid it to occur the damages such as fracture.
As the improvement to the present embodiment, described intake valve base 4 and exhaust valve base 5 are straight tube structure, and this improvement makes it less to the resistance of air-flow, are conducive to the intake and exhaust efficiency improving motor.
What finally illustrate is, above embodiment is only in order to illustrate technological scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technological scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
