Abstract
A kind of seal with annular groove muscle structure of automobile engine gasket seal, its seal with annular groove muscle assumes diamond in shape network distribution, and each side in the middle of it is respectively connected together, is trapped among around the cylinder of gasket seal mouthful；The section of its seal with annular groove muscle is into triangle sharp edge type shape.The sharp basil degree of its seal with annular groove muscle is between the o of 120 o~150.Advantage is, possess good sealing effectiveness, the generation of the bad phenomenon can be avoided as far as possible, and production cost is low, safe and reliable and use occasion is flexible, it can be used for relatively low closed with high field of pressure, be suitable for the automobile engine of most models on the market.
Description
Technical field
The utility model is related to a kind of seal with annular groove muscle structure of automobile engine gasket seal.
Background technology
Car engine secret cylinder pad is located between cylinder head and cylinder block, its act on be fill up cylinder head and cylinder block it
Between microscopic void, it is ensured that there is good sealing at faying face, and then combustion chamber is remained absolute closing,
The phenomenon of cylinder leakage tester, oil leak and water jacket leak can be avoided to occur, with continually strengthening for automobile engine, thermic load and machinery
Load is continuously increased, and the sealing property for improving gasket seal is particularly important.And to the requirement of gasket seal sealing property most
High position is the sealed muscle around cylinder mouthful, and sealed muscle subjects more than 70% thermic load and mechanical load, Gu Gangkou at this
The quality of sealed muscle will directly affect the normal operation of engine.
Common gasket seal mainly has metallic packing, asbestos seal gasket, without asbestos seal pad on the market at present
Piece, because asbestos seal gasket has certain toxicity, causes the proportion of its occuping market share fewer and fewer, and close without asbestos
Gasket high temperature resistant and it is corrosion-resistant in terms of not as the effect of metallic packing it is good, so in engine field of sealing technology,
Proportion shared by metallic packing is increasing, but each model automobile engine uses metallic packing at present, according to
So it there is the bad phenomenons such as cylinder leakage tester, oil leak and water jacket leak, therefore the not good enough serious restriction of gasket seal quality
The development of Engine Industry.
The content of the invention
The purpose of this utility model is to solve that above-mentioned the problems of existing there is provided a kind of preferable vapour of sealing property
The seal with annular groove muscle structure of car engine gasket seal.
The technical solution adopted in the utility model is：Its seal with annular groove muscle assumes diamond in shape network distribution, every in the middle of it
Individual side is respectively connected together, and is trapped among around the cylinder of gasket seal mouthful；The section of its seal with annular groove muscle is into triangle sharp edge type shape.
The sharp basil degree of its seal with annular groove muscle is between the o of 120 o~150.
During individual layer gasket seal, the seal with annular groove muscle in the end edge of rhombus two is in opposite direction, the cylinder mouthful on middle each side
Sealed muscle direction is consistent；During double-layer seal pad, the seal with annular groove muscle direction on every layer of gasket seal is consistent.
The utility model has the advantages that, the sealed muscle at cylinder mouthful is carried out to the distribution of network battle array structure, can started
During machine normal work, it is uniformly distributed born mechanical load, thermic load etc., it is to avoid stress is concentrated, to rush cylinder etc. bad
Seal with annular groove muscle in the generation of phenomenon, the end edge of rhombus two can be close according to actual conditions, i.e. individual layer gasket seal or double-deck pad
Envelope, the adjustment of travel direction, during individual layer gasket seal, because pressure is relatively low, network battle array is equivalent to making seal with annular groove
Muscle carries out the sealing of the sharp sword muscle of individual layer, and in the higher double-deck gasket seal of pressure, and now network battle array is equivalent to making cylinder
Mouth sealed muscle carries out the sealing of double-deck sharp sword muscle, makes it the environment preferably suitable for supercharging, i.e. the utility model uses field
Composition and division in a proportion is more flexible, can with workplace the need for its structure is changed accordingly, in addition, in the middle of rhombus on each side
Seal with annular groove muscle can play a part of the end edge upper cylinder half mouthful sealed muscle of support protection rhombus two, make the seal with annular groove muscle in two end edges
When engine works, it is to avoid situation about failing occur.
Its section concrete structure of seal with annular groove muscle is triangle sharp edge type, and the linear sealing to cylinder system can be achieved,
And the seal form can farthest be sealed to combustion gas, cooling water, machine oil, the hair of leakage phenomenon can be effectively prevented from
It is raw.
At present, metallic packing is as the gasket seal being most widely used in engine field of sealing technology, therefore close to its
The research of sealing property is significant, and the utility model is easily let out summarizing current gasket seal existing on the market
It is designed after the bad phenomenons such as dew, damage cylinder, by practice test, the utility model possesses good sealing effect
Really, the generation of the bad phenomenon can be avoided as far as possible, and production cost is low, safe and reliable and use occasion is flexible,
It can be used for relatively low closed with high field of pressure, be suitable for the automobile engine of most models on the market, and this is close
Gasket has very strong epitaxy, is not only widely applied in automobile engine field of sealing technology, and expansible extension
To other sealed fields of needs such as space flight and aviation, ship and lifes staying idle at home, therefore belong to preferably practical example, with certain popularization
Value.
Brief description of the drawings
Fig. 1 is the utility model gasket seal schematic diagram；
Fig. 2 is enlarged diagram at Fig. 1 A；
Fig. 3 is Fig. 2 Section A-A schematic diagram；
Fig. 4 is individual layer gasket seal partial duty view.
Fig. 5 is double-layer seal pad partial duty view.
Embodiment
Describe in detail below in conjunction with the accompanying drawings：As illustrated, its seal with annular groove muscle assumes diamond in shape, network is distributed, in the middle of it
Each side is respectively connected together, and is trapped among around the cylinder of gasket seal mouthful；The section of its seal with annular groove muscle 1 is into triangle sharp edge type
Shape.
The sharp basil degree a of its seal with annular groove muscle 1 is between the o of 120 o~150.
During individual layer gasket seal, the seal with annular groove muscle 1 in the end edge of rhombus two is in opposite direction, the cylinder mouthful on middle each side
The direction of sealed muscle 1 is consistent；During double-layer seal pad, the direction of seal with annular groove muscle 1 on every layer of gasket seal is consistent.
When automobile engine is in normal work, gasket seal is under the multiple action of thermic load and mechanical load
In one HTHP and perishable dynamic environment, wherein, gasket seal is subject at cylinder mouth from engine more than 70%
Load, now the load that cylinder system can be brought of structure distribution of seal with annular groove muscle network battle array divide equally and be distributed,
Not only make seal with annular groove muscle keep closely contacting with cylinder system time, and be less prone to stress concentration, damage
The situation of cylinder, can finally realize the absolute static seal under dynamic operation condition.
