Abstract
The utility model discloses a cylinder gasket for high horse power diesel engine, including the jar advance capital for body, be equipped with cylinder hole, oilhole, water hole and bolt hole on the jar advance capital for body, the jar advance capital for body is including upper plate, hypoplastron and establish the adjusting plate between upper plate and hypoplastron, and its special character is: be close to the downthehole reason of cylinder and set firmly the spacing piece of annular between upper plate and adjusting plate, do not be equipped with annular sealing rib in corresponding spacing punishment of the surface of upper plate and hypoplastron, the position is relative just near spacing piece outer fringe about the annular sealing rib on upper plate and the hypoplastron. The beneficial effects are that: through the spacing piece of annular carrier ring shape sealing rib's deformation pressure more effectively, the deformation of cylinder cap made sealing performance reliable when elastic deformation through the relative annular sealing rib in upper and lower position can compensate the engine outburst, can avoid haring the engine cylinder lid.
Description
Technical field
This utility model relates to a kind of cylinder head gasket structure, particularly to a kind of high-power cylinder used for diesel engine
Pad.
Background technology
At present, the limit part of existing diesel engine cylinder pad cylinder port part typically uses soft state corrosion resistant plate
The structure of flange is relatively big at engine flare pressure and when working long hours, through repeatedly vibrating easily at flange
Produce cracking, cause the insecure risk of sealing.Another kind of structure is that upper and lower plates uses hard state corrosion resistant plate,
The limit part of head gasket cylinder port part uses the structure of ring packing muscle, owing to ring packing muscle wall scroll seals
Muscle height is 0.15mm, and when fastening, at sealed muscle, pressure values is the highest, when engine cylinder cover hardness is slightly lower,
Likely damage engine cylinder cover.
Summary of the invention
It is reliable that technical problem to be solved in the utility model is to provide a kind of sealing property, can avoid damage to send out
The high-power head gasket used for diesel engine of motivation cylinder cap.
For solving the problems referred to above, this utility model adopts the following technical scheme that
A kind of high-power head gasket used for diesel engine, including cylinder pad body, is provided with cylinder on cylinder pad body
Hole, oilhole, water hole and bolt hole, described cylinder pad body includes upper plate, lower plate and is located at upper plate and lower plate
Between adjustment plate, it is characterized in that: be installed with ring near cylinder-bore inner edge between upper plate and adjustment plate
Shape banking stop, is respectively equipped with ring packing muscle at upper plate banking stop corresponding with the outer surface of lower plate, upper plate and
Ring packing muscle upper-lower position in lower plate is relative and near banking stop outer rim.
As further preferably, the thickness of described banking stop is 0.1mm.
As further preferably, described banking stop and adjustment plate, by Laser Welding circumference soldering, are used for guaranteeing limit
The position of bit slice is fixed.
As further preferably, cylinder pad body is positioned at each oilhole and water hole is respectively equipped with rubber ring,
The skeleton of rubber ring is inserted respectively into corresponding oilhole and the inner edge, water hole annular groove between upper plate and lower plate
In.
As further preferably, connected by spot welding between described upper plate, lower plate and adjustment plate, raw to improve
Produce efficiency, reduce cost.
The beneficial effects of the utility model are: due to fixed near cylinder-bore inner edge between upper plate and adjustment plate
There is annular stop sheet, at upper plate banking stop corresponding with the outer surface of lower plate, be respectively equipped with ring packing muscle, logical
Cross annular stop sheet and can more effectively carry the rock deformation pressure of annular sealed muscle, relative by upper-lower position
The deformation of cylinder cap when the elastic deformation of ring packing muscle can make up engine flare, makes sealing property reliable,
Engine cylinder cover can be avoided damage to.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view Amplified image of Fig. 1.
In figure: cylinder pad body 1, cylinder-bore 101, oilhole 102, water hole 103, bolt hole 104, lower plate 2,

With bolt hole 104, the present embodiment as a example by 102, two water holes 103 of three oilholes and four bolts hole 104,
Oilhole and water hole are respectively provided at the both sides of cylinder-bore 101, and bolt hole is distributed in the surrounding of cylinder-bore 101.
Described cylinder pad body 1 includes upper plate 5, lower plate 2 and is located at the adjustment plate between upper plate 5 and lower plate 2
3, between upper plate 5 and adjustment plate 3, it is installed with annular stop sheet 4, described limit near cylinder-bore 101 inner edge
The thickness of bit slice 4 is preferably 0.1mm.Set respectively at upper plate 5 banking stop 4 corresponding with the outer surface of lower plate 2
Having ring packing muscle 7, the cross section of this sealed muscle is arc convex, the ring packing on upper plate 5 and lower plate 2
Muscle 7 upper-lower position is relative and near banking stop 4 outer rim.
As preferably, described banking stop 4 and adjustment plate 3, by Laser Welding circumference soldering, are used for guaranteeing spacing
The position of sheet 4 is fixed.Between described upper plate 5, lower plate 2 and adjustment plate 3 by the spot welding of several some positions even
Connect, to improve production efficiency, reduce cost.
As preferably, cylinder pad body 1 is positioned at each oilhole and water hole is respectively equipped with rubber ring 6, rubber
Ring 6 is to be made up of skeleton and the rubber ring being located on skeleton, and the skeleton of rubber ring 6 is inserted respectively into corresponding oil
In the annular groove between upper plate 5 and lower plate 2 of hole and inner edge, water hole.
Although embodiment of the present utility model is disclosed as above, but it is not restricted to description and enforcement
Listed utilization in mode, it can be applied to various applicable field of the present utility model completely, for being familiar with
