Valve retainer material, it is cheap, but hot properties is poor, is mainly used in the not high Cast Iron Cylinder Head diesel engine of reinforcing degree
Exhaust valve seat insert.Once high chromium valve retainer material is DIN, is mainly used in high-power ship machine, the Weihe River mattress temperature of river bavin
High-chromium alloy is used for gas engine exhaust valve seat insert by high diesel engine, the country extensively.
Valve retainer is arranged in cylinder head, and air cylinder head structure now becomes increasingly complex, and there also is provided inside cylinder head
Water channel and air flue, and the position for installing valve retainer can not change.Because present diesel engine power is strengthened, explosion pressure increases
Add, thermic load increase, and valve is while HTHP is born, it is also necessary to high-frequency opening and closing action is done, therefore
Cause valve retainer to frequently occur release failure, circle situation that what cylinder cap easily occurred in use lose places, can cause to start
Machine damages, and can not use.
Utility model content
In view of this, the utility model provides a kind of cylinder head, can effectively reduce cylinder cap and lose places in use
The situation of circle.
A kind of cylinder head, including cylinder cap body, the cylinder cap body upper surface offer stomata, the stomata include into
Stomata, steam vent, the air admission hole, steam vent are connected with air intake duct, exhaust duct respectively, the inner circumferential of the air admission hole and steam vent
Circle is provided with seat ring, the seat ring and this body by integral forming of cylinder cap.
Original cylinder technique is finished again after inlaying seat ring, and the utility model is carried out to cylinder cap body construction,
Technique after improvement is the processed finished products directly on cylinder cap, seat ring part is formed an entirety with cylinder cap, in valve sealing portion
Point high-frequency quenching makes its hardness reach the hardness for inlaying seat ring, in the utility model, cylinder cap body construction is improved, more
Technique seat ring part after changing and cylinder cap are an entirety, by the situation for the circle that effectively avoids losing places.
Preferably, the interior border of the seat ring is provided with screw thread, and the seat ring upper end open is more than lower ending opening.With gas
Screw thread inside the seat ring of cylinder cylinder cap one can prevent releasing for connection member, while be advantageous to keep the sealing of junction
Property, upper shed is more than under shed and is then mounted and taken out beneficial to connection member.
More preferred, in one embodiment of the present utility model, the seat ring is equal in magnitude, shape is identical.
Preferably, the stomata has six groups, and every group of stomata includes two air admission holes and two steam vents, and six groups of stomatas are uniform
It is distributed in cylinder cap body upper surface.
More preferred, the cylinder cap body upper surface is located at offers water channel hole per between two adjacent groups stomata.It is described
Water channel hole is connected with water channel, and the water channel is arranged at cylinder cap body interior, is set around air intake duct and exhaust duct.
Preferably, the cylinder cap body interior is provided with inlet plenum along cylinder cap body length direction, and the inlet plenum is with entering
Air flue connects.
The beneficial effects of the utility model are：The utility model makes technique by the improvement to cylinder head body construction
Seat ring part turns into an entirety with cylinder cap, it is possible to prevente effectively from the circle situation of losing places that cylinder cap easily occurs in use,
So as to avoid the damage of engine.Simultaneously stomata, water channel hole and the air intake duct of inside on cylinder cap body, exhaust duct, water channel, enter
Air chamber is reasonably distributed, and is effectively saved space and is avoided the occurrence of failure.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model structure；
Fig. 2 is the partial cutaway schematic at the utility model air admission hole seat ring position.
Fig. 3 is the partial cutaway schematic at the utility model steam vent seat ring position.
Wherein, 1 it is cylinder cap body, 2 be stomata, 21 be air admission hole, 22 be steam vent, 3 be air intake duct, 4 is exhaust duct, 5
It is water channel hole, 7 inlet plenums for seat ring, 6.
Embodiment
A kind of cylinder head provided by the utility model is further described below in conjunction with specific embodiment.
A kind of sand prevention water fetching device, as shown in accompanying drawing 1,2, it can be seen that this cylinder head, including cylinder cap sheet
Body 1, the upper surface of cylinder cap body 1 offer stomata 2, and the stomata 2 includes air admission hole 21, steam vent 22.It is specifically, described
Stomata 2 has six groups, and every group of stomata 2 includes two air admission holes 21 and two steam vents 22, and six groups of stomatas 2 are uniformly distributed in cylinder cap sheet
