Description
Technical field
The present invention relates to a kind of rubber sheet gaskets.
Background technique
In order to guarantee the leakproofness between two components, the gasket of different size would generally be set between the two parts,
Not only pattern is different for these gaskets, and material multiplicity, there is the mixing of metal, fiber, rubber, plastics and multiple material, this
A little gaskets ensure that the leakproofness between two components.In section structure, since contact surface is larger, need in two components
Between outer rim and inner edge formed two seals, current Normal practice be setting two corresponding gaskets be separately mounted to two
The outer rim of member seal face and inner edge, two gaskets need to be accurately positioned during installation, just can guarantee that bolt can pass through just
Through-hole on gasket, the gasket positioned at outer rim can be positioned relatively accurately, and be located at the gasket of inner edge since operating space is narrow
It is small, so that the position for gasket is adjusted by biggish limitation, generally require repeatedly can just be adjusted in place, this is not only increased
The working time of installation personnel and working strength, but also it is affected to some extent installation quality.
Summary of the invention
To solve the above problems, the invention proposes a kind of rubber sheet gasket, the rubber sheet gasket can be effectively reduced for
The adjustment number of gasket improves working efficiency, and specific technical solution is as follows:
A kind of rubber sheet gasket comprising shim body annular in shape, shim body include the first washer, are located at the first pad
It encloses the second packing ring of inside and connects the intermediate ring body of the first washer and second packing ring；Around gasket sheet on the first washer
The central axes of body are evenly arranged with several groups cycle hole, and every group of cycle hole includes one for wearing the first fixation hole and one of bolt
The center of first positioning hole used for positioning, the first fixation hole and first positioning hole is located on the same circle；The ring in second packing ring
It is evenly arranged with several groups inner ring hole around the central axes of shim body, every group of inner ring hole includes one solid for wearing the second of bolt
Determine hole and a second location hole used for positioning, the center of the second fixation hole and second location hole is located on the same circle.
In the present invention, two washers, respectively the first washer and second packing ring are set, among two washers among setting
Ring body, intermediate ring body connect the first washer and second packing ring, when the first washer and second packing ring be known as an entirety,
When the outside of part of appliance is adjusted gasket, it can be completed at the same time the adjustment to the first washer and second packing ring, not only may be used
Effectively improve the installation speed of gasket, moreover it is possible to improve the installation accuracy of gasket, guarantee the leakproofness at component connecting sewing.To mention
The operating flexibility of this high gasket is provided with one used for positioning the beside each the first fixation hole for wearing bolt
A positioning hole is provided with a second location hole used for positioning beside each the second fixation hole for wearing bolt, with
It is conveniently used for being provided with the connection of the component of positioning region.Since for rubber material, this rubber sheet gasket can be improved with one-pass molding
Processing efficiency.
Further, at least side of shim body, the inside portion of the first washer be provided at least one in the axial direction to
The first seal line in a ring of outer protrusion, first seal line extend around the central axes of shim body.Preferably, in gasket
The two sides of ontology are provided at least one the first sealing in a ring outwardly protruded in the axial direction in the inside portion of the first washer
Line, first seal line extend around the central axes of shim body.
Further, at least side of shim body, the outside portion of second packing ring be provided at least one in the axial direction to
The second seal line in a ring of outer protrusion, second seal line extend around the central axes of shim body.Preferably, in gasket
The two sides of ontology are provided at least one the second sealing in a ring outwardly protruded in the axial direction in the outside portion of second packing ring
Line, second seal line extend around the central axes of shim body.
First seal line and being provided with for the first seal line are conducive to improve the leakproofness between two components.
Further, the thickness of the intermediate ring body less than the first washer thickness, and be less than second packing ring thickness.It is preferred that
Ground, in the axial direction, the either side of intermediate ring body relative to the recessed towards identical side of the first washer, and relative to
Second packing ring it is recessed towards identical side.Make the thickness of intermediate ring body less than the first washer and the thickness of second packing ring
Afterwards, after the setting between the two parts of this rubber sheet gasket, during two components are fastened, the first washer and the second pad
A certain amount of deformation can occur for circle, since the thickness of intermediate ring body wants thinner, the inside of the first washer and second packing ring
The deformed part in outside can be prominent to middle section, avoid the first washer and second packing ring from generating fold, influence two portions
Sealing effect between part.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of embodiment of the invention.
Fig. 2 be in Fig. 1 A-A to view.
Fig. 3 is the enlarged drawing of part B in Fig. 2.
Specific embodiment
Embodiment 1:
Refering to fig. 1~Fig. 3, a kind of rubber sheet gasket comprising shim body 10 annular in shape, shim body 10 include the
One washer 11, the second packing ring 13 on the inside of the first washer 11 and the centre for connecting the first washer 11 and second packing ring 13
Ring body 12；Central axes Y on the first washer 11 around shim body 10 is evenly arranged with several groups cycle hole, every group of cycle hole
