Description
Technical field
The present invention relates to diesel engine system field, and in particular to a kind of practical sealing cylinder component.
Background technology
The quality of cylinder head sealing property, directly affects the technology status of engine, when serious, and the power of engine is drastically
Decline, or even can not work.Such as after head gasket scaling loss, the cylinder compression power of engine is not enough, and its rotating speed is decreased obviously, and companion
There is blast pipe to smolder (white cigarette), have bubble generation in water tank and cooling-water consumption is too fast, the phenomenon such as organic oil whip of product on the water surface.
Many machine hands do not know the reason for cylinder gasket is damaged, and only know the cylinder gasket more renewed, as a result the continuous scaling loss of cylinder gasket.
, mainly there is the following aspects the reason for influence cylinder cover airtight quality：1：The use of cylinder gasket is with installing not
Correctly.Cylinder gasket is installed between engine cylinder block and cylinder head, and its effect is the sealing for ensureing combustion chamber, prevents combustion
Gas, cooling water and lubricating oil are leapt up Lou, so, the use of cylinder gasket is undesirable with installing, and just directly affects cylinder head
Sealing reliability and head gasket service life.2：Cylinder head or cylinder body plane are spent greatly.Warpage and distortion are that cylinder head usually goes out
Existing the problem of, be also the main cause for causing cylinder gasket to burn repeatly.Particularly aluminium alloy cylinder lid shows more prominent, and this is
Because aluminum alloy materials have very high heat conduction efficiency, while cylinder head is compared with cylinder block, seem smaller and thin again, that
The temperature of aluminium alloy cylinder lid rises soon.When cylinder-head distortion, it is engaged with cylinder body plane will not be tight, then,
The airtight quality of cylinder just declines, and causes gas leakage and burns out cylinder gasket, so as to deteriorate further the airtight quality of cylinder.3：
Cylinder surface inhomogeneous cooling can form hot localised points.Hot localised points can cause the metal of zonule in cylinder head or cylinder block to produce
Raw excessively expansion, this expansion can make cylinder head gasket piece be extruded and damaged.Because the damage of cylinder gasket causes to let out
Dew and the generation of corrosion, and finally burnt.
The content of the invention
It is an object of the invention to provide a kind of practical sealing cylinder component, solve cylinder surface inhomogeneous cooling and formed
Hot localised points cause the metal of zonule in cylinder head or cylinder block to produce excessive expansion, cause cylinder head gasket piece by crowded
The problem of pressing and damage.
The present invention is achieved through the following technical solutions：
A kind of practical sealing cylinder component, including the cylinder head and cylinder block being connected with each other by head gasket, the gas
The end face that cylinder cap is connected with cylinder liner is internally provided with the first cooling duct, the center line of first cooling duct to cylinder head
The vertical range of end face is 3~5mm, and valve port surrounding of first cooling duct in cylinder head be uniformly distributed, in cylinder head
Side be provided with the first water inlet pipe and the first outlet pipe, one end of first water inlet pipe and the first outlet pipe is cold with first
But passage is communicated, the other end is connected with coolant circulation unit；
The end face that the cylinder block is connected with head gasket is internally provided with the second cooling duct, second cooling duct
The vertical range of center line to cylinder block end face is 5~8mm, and valve port surrounding of second cooling duct in cylinder block is uniform
Distribution, the second water inlet pipe and the second outlet pipe are provided with the side of cylinder block, second water inlet pipe and the second outlet pipe
One end is communicated with the second cooling duct, the other end is connected with coolant circulation unit.Further, ground for a long time through inventor
Study carefully discovery, because temperature is higher near valve port, expansion of metal degree is compared near the valve port in cylinder head or cylinder block
The expansion of metal degree at cylinder head or cylinder block edge is much bigger, and this expansion can make cylinder head gasket piece be extruded and damaged
It is bad.And this expansion can cause cylinder in the course of the work, the cylinder head internal stress linked together with cylinder block is uneven,
Cylinder head end face is caused crackle occur.So the present invention devises a kind of new cylinder cover structure, in cylinder head and cylinder
Cooling duct is respectively provided with inside the end face that body contacts with each other, i.e., the first cooling duct is set inside cylinder head end face, in cylinder
Second cooling duct is set in vivo, and valve port surrounding of the cooling duct all in cylinder head is uniformly distributed, and makes cooling with this
Coolant in liquid circulating device enters cooling duct from water inlet pipe, takes away near the valve port on cylinder head or cylinder block end face
Heat, the temperature near valve port is reduced with this, the problem of reaching solution cylinder surface inhomogeneous cooling formation hot localised points.
Combustion gas is entered in the combustion chamber in cylinder head by valve port, so cylinder head persistently can be pointed to cylinder by one by cylinder block
The impulsive force of lid, the surface temperature of cylinder head end face is higher, by the center line of the first cooling duct to the vertical of cylinder head end face
Distance is 3~5mm, and the vertical range of center line to the cylinder block end face of the second cooling duct is 5~8mm, is ensureing that end face is strong
In the case of degree, the radiating of end face between cylinder cover can be improved.Here coolant circulation unit can external connection automobile water
Case, it can also use special cooling liquid device.
The first groove is provided with the outside of the end face that the cylinder head is connected with cylinder liner, what the cylinder block was connected with head gasket
Also be provided with the second groove on the outside of end face, first groove and the second groove contact with each other to be formed after cavity with cylinder liner outer surface
It is mutually matched.Further, the first groove and the second groove, the first groove and cylinder are opened respectively in the gentle cylinder body end face of cylinder head
The opposite side surface matching of the side surface matching of pad, the second groove and cylinder block, when the first groove and the second groove are closed one
After rising, the cavity formed just makes cylinder liner be limited in cavity, after the cylinder head, cylinder block, cylinder of this structure are fixed,
Cylinder can be effectively reduced in the course of work, head gasket produces relative displacement because of vibrations, cause asking for cylinder seal effect reduction
Topic.
The present invention compared with prior art, has the following advantages and advantages：
1st, a kind of practical sealing cylinder component of the present invention, by setting cooling logical inside cylinder cover connecting end surface
Road, and cooling duct is uniformly distributed around valve port surrounding, takes away valve hole end surface heat by coolant, effectively solves
Cylinder surface inhomogeneous cooling formation hot localised points cause the metal of zonule in cylinder head or cylinder block to produce excessive expansion, cause
Make the problem of cylinder head gasket piece is extruded and damaged；
2nd, a kind of practical sealing cylinder component of the present invention, by the equal recessing of cylinder cover end face, the first groove outputed
Contact with each other to be formed after cavity with the second groove and be mutually matched with cylinder liner outer surface, cylinder is effectively reduced in work with this
Process, head gasket produces relative displacement because of vibrations, causes the problem of cylinder seal effect is reduced, and can extend the use of cylinder liner
It is life-span, economical and practical.
