Description
Technical field
The present invention relates to technical field of engines, and in particular to a kind of durable modified cylinder seal part.
Background technique
The quality of cylinder head sealing performance directly affects the technology status of engine, and when serious, the power of engine is sharply
Decline, or even can not work.Such as after head gasket scaling loss, the cylinder compression power of engine is insufficient, and revolving speed is decreased obviously, and companion
There is exhaust pipe to smolder (white cigarette), has bubble generation in water tank and cooling-water consumption is too fast, on the water surface phenomena such as product organic oil whip.
Many machine hands do not know the reason of cylinder gasket damage, only know the cylinder gasket more renewed, as a result the continuous scaling loss of cylinder gasket.
The end face that head gasket in the prior art is contacted with cylinder cover is smooth surface, in engine working process
In, because cylinder cover can generate slight bounce so that generating relative displacement and cylinder table between cylinder cover and head gasket
Face inhomogeneous cooling is even and generates hot localised points, and it is excessively swollen that hot localised points cause the metal of zonule in cylinder head or cylinder block to generate
Swollen and squeeze cylinder head gasket piece, these, which can all be damaged, leads to occur gap between head gasket and cylinder cover, leads
Cause engine performance decline.
Summary of the invention
The purpose of the present invention is to provide a kind of durable modified cylinder seal part, solve head gasket and cylinder cover it
Between tightness it is poor, the problem of influencing engine performance.
The present invention is achieved through the following technical solutions:
A kind of durable modified cylinder seal part, including cylinder head, cylinder block, head gasket, the head gasket are located at gas
Between cylinder cap and cylinder block, several the first sawtooth grooves are provided on two end faces of head gasket, first sawtooth is recessed
Slot is uniformly distributed on the end face of head gasket, is provided with several on the end face that cylinder head and cylinder block are contacted with head gasket
Second sawtooth grooves, second sawtooth grooves are mutually matched with the first sawtooth grooves.Further, the present invention devises one kind
Novel air cylinder lid sealing structure, so that connected between cylinder cover and head gasket by the mutually matched mode of sawtooth grooves,
Cylinder head, cylinder block, contact area and depth between head gasket are increased with this, so that its integral piece stability is stronger, it is close
That seals is even closer.Be covered with the cylinder head of sawtooth grooves, cylinder block, head gasket end face form a blade type sealing surface, should
Blade type sealing surface reduces cylinder head, cylinder block and head gasket in the contact squeeze face of vertical direction, reduces sealing area, institute
To be obtained with a big seal pressure with a lesser applied force, good, stable sealing effect can be obtained, into one
Step improves the tightness between head gasket and cylinder cover, and the service life of head gasket is extended with this.
It is opened on the cylinder head, cylinder block end close to each other there are two square groove, the square groove is located at
The circumferential direction of cylinder head or cylinder block also has a notch at the both ends of head gasket, and the notch is about head gasket
Center line it is symmetrical, further include fixed block, when two end faces of cylinder head, the end face of cylinder block and head gasket are connected as one
When, two square grooves synthesize a rectangular recess with the notch of head gasket, the fixed block be completely disposed in rectangular recess and
It is matched with rectangular recess inner surface.Further, when two end faces of cylinder head, the end face of cylinder block and head gasket are connected as one
When body, two square grooves synthesize a rectangular recess with the notch of head gasket, fixed block are placed in rectangular recess, whole shape
At the structure that a flat key connects, when the vibrations are up and down, fixed block will not fall off for fixed cylinder head, cylinder by this method,
Sealing structure is more stable.
Preferably, it is also provided with a through-hole on fixed block, is also provided with a mounting hole in the circumferential direction of head gasket, also
Including bolt, the bolt passes through through-hole and fixes with mounting hole.Bolt plays fixed block, head gasket, cylinder head, gas further
The effect that cylinder body links together.
Preferably, the depth of first sawtooth grooves along the vertical direction is 1.5~2.5mm.Guarantee cylinder head, gas with this
Contact area and depth between cylinder body, head gasket.
Compared with prior art, the present invention having the following advantages and benefits:
Durable modified cylinder seal part of the invention a kind of increases cylinder head, cylinder block, the contact between head gasket
Area and depth so that its integral piece stability is stronger, sealing it is even closer, and sealing area is reduced, so with one
A lesser applied force is obtained with a big seal pressure, can obtain good, stable sealing effect, further increase
Tightness between head gasket and cylinder cover, extends the service life of head gasket with this, practicability with higher and
Economic value.
