Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of sealing element.
Background technique
Sealing element is sealing ring, and common sealing element is O-ring seal, and O-ring seal is a kind of two-way function sealing
Element, by initial compression ability radially or axially when installation, to determine its initial sealability.And sealing ring it
Between be connected with each other and be more troublesome, the stability of connection is to be improved.
Summary of the invention
The purpose of this utility model is the presence of the above problem in view of the prior art, proposes that a kind of structure is simple, sealing
The good sealing element of effect.
The purpose of this utility model can be realized by the following technical scheme: a kind of sealing element, including with a central hole
Ontology, it is characterised in that: tool is in semicircle there are two annular inner seal ring, the section of annular inner seal ring on the inner wall of centre bore
Shape and two annular inner seal rings are separately positioned at the 1/3 and 2/3 of centre bore has an annular in outer body wall medium position
Gap width between the width of outer seal ring and annular outer seal ring and two annular inner seal rings is identical, and surface has on the body
There is protrusion in twice annular, there is annular lower convexity together in ontology lower surface, the circular diameter that annular lower convexity is constituted is equivalent
The circular diameter that gap is constituted between the upper protrusion of two annulars.
Compared with prior art, the utility model is made by the way that annular inner seal ring is arranged on the inner wall in heart hole in the body
This sealing element when being installed on the sealing realized on workpiece in the radial direction, be squeezed between two annular inner seal rings and workpiece
Form good sealed connection, only there are two point and workpiece contact connectios instead of original whole for two annular inner seal rings
A center bore inner wall face and workpiece connect, so that smoothly, the annular on outer body wall is outer for ratio when workpiece moves up and down
Sealing ring can extrusion forms good sealed connection between workpiece when body outer wall is squeezed, in radial direction
On when needing to place sealing element, the annular outer seal ring inlay card on the sealing element in inner ring is on the sealing element in outer ring
Gap between two annular inner seal rings, to facilitate positioning, when ontology upper and lower surface is squeezed by workpiece, in annular protrusion and
Annular lower convexity stress deformation, the deformed upper protrusion of annular and annular lower convexity can be in close contact with workpiece, and it is close to form multiple tracks
Envelope is needing multiple sealing elements to be superimposed in use, annular lower convexity inlay card on upper point sealing element is in being in
The gap between the upper protrusion of two annulars on the sealing element of lower section, to facilitate positioning.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model and valve rod.
In figure, 1, ontology；11, centre bore；12, annular inner seal ring；13, annular outer seal ring；14, raised in annular；
15, annular lower convexity.
Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, this sealing element includes the ontology 1 with centre bore 11, on the inner wall of centre bore 11 there are two tools
Annular inner seal ring 12, the section semicircular in shape of annular inner seal ring 12 and two annular inner seal rings 12 are separately positioned on centre bore
At the 1/3 of 11 and 2/3, there is the width of an annular outer seal ring 13 and annular outer seal ring 13 in 1 lateral wall medium position of ontology
Degree is identical as the gap width between two annular inner seal rings 12, has protrusion 14 in twice annular in 1 upper surface of ontology, at this
1 lower surface of body has annular lower convexity 15 together, and the circular diameter that annular lower convexity 15 is constituted is equal to the upper protrusion 14 of two annulars
Between the circular diameter that is constituted of gap.
By the way that annular inner seal ring 12 is arranged on the inner wall of 1 centre bore 11 of ontology, so that this sealing element is installed on workpiece
When the upper sealing realized in the radial direction, extrusion forms good sealing between two annular inner seal rings 12 and workpiece
Connection, two 12, annular inner seal rings are there are two point with workpiece contact connectio instead of original 11 inner wall of entire centre bore
Connected with workpiece so that when workpiece moves up and down ratio smoothly, while its semicircular cross section of annular inner seal ring 12
But also workpiece moves up and down annular outer seal ring 13 that is more smooth, while being set on 1 lateral wall of ontology, it can be in ontology
Extrusion forms good sealed connection, and the width of annular outer seal ring 13 between workpiece when 1 outer wall is squeezed
Gap width between two annular inner seal rings 12 is identical, when so that needing to place multiple sealing elements in radial directions, place
In 13 inlay card of annular outer seal ring on the sealing element of inner ring in outer ring sealing element on two annular inner seal rings 12 it
Between gap, to facilitate positioning.
Protrusion 14 and annular lower convexity 15 in annular is respectively set in 1 upper and lower surface of ontology, when 1 upper and lower surface of ontology is by work
When part squeezes, the upper protrusion 14 of annular and 15 stress deformation of annular lower convexity, the deformed upper protrusion 14 of annular and annular lower convexity
15 can be in close contact with workpiece, and above protrusion 14 and annular lower convexity 15 are in close contact annular with workpiece, and formation is multiple-sealed,
And the circular diameter that annular lower convexity 15 is constituted is equal to the circular diameter that gap is constituted between the upper protrusion 14 of two annulars, is needing
Multiple sealing elements are wanted to be superimposed in use, 15 inlay card of annular lower convexity on upper point the sealing element is in being below
The gap between the upper protrusion 14 of two annulars on sealing element, to facilitate positioning.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
