Specific embodiment
As shown in Figure 1-3, Fig. 1 be the utility model proposes a kind of instrumentation sealing ring axonometric drawing, Fig. 2 be this
Utility model propose a kind of instrumentation sealing ring sectional view, Fig. 3 be the utility model proposes a kind of instrumentation
With the partial enlarged view of sealing ring.
Referring to Fig.1-3, the utility model proposes a kind of instrumentation sealing ring, including sealing ring body 1, sealing ring
Ontology 1 has the first sagittal plane and the second sagittal plane, and the first sagittal plane and the second sagittal plane extremely sealing ring body 1 are along axial direction
Both sides of the face, sealing ring body 1 are made of rubber material；
Referring to Fig.1-2, the first sagittal plane is equipped with multiple first arc grooves 11, and multiple first arc grooves 11 are along sealing ring
Circumferentially, the first arc groove 11 and 1 coaxial line of sealing ring body, 11 depth direction of the first arc groove is along sealing ring sheet for ontology 1
Body 1 is axially extending, and projection of the first arc groove of arbitrary neighborhood 11 on 1 place annular surface of sealing ring body has lap；
Referring to Fig. 2, the second sagittal plane is equipped with multiple second arc grooves 12, and multiple second arc grooves 12 are along sealing ring sheet
Circumferentially, the first arc groove 11 and 1 coaxial line of sealing ring body, 12 depth direction of the second arc groove is along sealing ring body 1 for body 1
Axially extending, projection of the second arc groove of arbitrary neighborhood 12 on 1 place annular surface of sealing ring body has lap；
Toroidal cavity, toroidal cavity and 1 coaxial line of sealing ring body are equipped in sealing ring body 1, ring-like cavity cross section is
Rectangle, toroidal cavity is interior to be equipped with annular metal sheet 2, and the interior outside of annular metal sheet 2 is respectively with toroidal cavity along sealing ring radial direction
Opposing sidewalls be fixedly connected, thus by toroidal cavity along axially spaced formation first chamber 13 and second chamber 14, the first chamber
Room 13 and second chamber 14 are also in a ring that multiple first arc grooves 11 are connected to first chamber 13, multiple second arc grooves 12
It is connected to second chamber 14；
Filled with water suction item, first chamber 13 and the second chamber inside multiple first arc grooves 11 and multiple second arc grooves 12
Room 14 is filled with water-swellable material.
Outside moisture is penetrated into along the first sagittal plane or second facing radially towards gauge internal, when moisture content reaches the first arc groove
11 or when the second 12 position of arc groove, if the moisture content penetrated into is less, moisture content is only absorbed by water suction item, if the moisture content penetrated into compared with
More, moisture content is absorbed by water suction item, and under the guidance of water suction item, moisture content is penetrated into water-swellable material, leads to water-swellable
Material expansion, causes part of the sealing ring body 1 between first chamber 13 and the first sagittal plane to be squeezed and expands or close
Part of the seal ontology 1 between first chamber 13 and the first sagittal plane is squeezed and expands, so that the first sagittal plane
And second cooperate between sagittal plane and external object sealing surface even closer, formation blocks water barrier, and moisture content is prevented to continue to penetrate into；
And due to the presence of annular metal sheet 2, the water-swellable material in first chamber 13 is difficult to second chamber 14
Direction expansion, the volume that water-swellable material increases expand under the forcing of annular metal sheet 2 to the first sagittal plane direction, thus
So that the first radial surface expansion is obvious, cooperate between the first sagittal plane and external object sealing surface even closer；Similarly, the second chamber
Water-swellable material in room 14 is difficult to expand to 13 direction of first chamber, and the volume that water-swellable material increases is in endless metal
It is expanded under the forcing of plate 2 to the second sagittal plane direction, so that two radial surface expansions are obvious, the second sagittal plane and external object
Cooperate between sealing surface even closer.
In the present embodiment, any one radius of sealing ring body 1 passes through two the first arc grooves 11, sealing ring body
1 any one radius passes through two the second arc grooves 12；When moisture content is penetrated into along the first sagittal plane or the second sagittal plane, two
First arc groove 11 forms the twice barrier that blocks water and moisture content is prevented to penetrate into, and two the second arc grooves 12 form twice and block water barrier prevention
Moisture content penetrates into；Further increase the waterproof performance of sealing ring.
In order to enable water-swellable material can be expanded timely and effectively, water suction item extends into water-swellable material
In, to increase the contact area of water suction item and water-swellable material, so that water-swellable material can be timely and effectively after meeting water
It expands.
In the present embodiment, the water suction item in the first arc groove 11 is extended to outside the first arc groove 11, the second arc groove 12
Interior water suction item extends to outside the second arc groove 12, and the sealing surface of water suction item and external object squeezes, so that the first diameter
It can be absorbed water to the moisture content between moisture content, the second sagittal plane and the external object sealing surface between face and external object sealing surface
Item fully absorbs.
In the present embodiment, be fixed with the first metal cranse 3 on 1 interior annular face of sealing ring body, the first metal cranse 3 with
Sealing ring body 1 is coaxially set, and the second metal cranse 4, the second metal cranse are surrounded on 1 exterior annular face of sealing ring body
4 are coaxially set with sealing ring body 1；Since the first metal cranse 3 and the second metal cranse 4 are respectively by sealing ring body 1
Interior outside is waled, and when water-swellable material expansion, the volume that water-swellable material increases is difficult to prolong along 1 radial direction of sealing ring body
It stretches, and due to the presence of annular metal sheet 2, the volume that the water-swellable material in first chamber 13 increases can only be radial to first
Face side extends, and the volume that the water-swellable material in second chamber 14 increases can only extend to the second sagittal plane side, thus
So that the first sagittal plane and the second radial surface expansion are obvious.
Referring to Fig. 2-3, the exterior annular face of sealing ring body 1 is equipped with multiple first inlet openings 15, multiple first water inlets
Hole 15 is connected to first chamber 13；The exterior annular face of sealing ring body 1 be equipped with multiple second inlet openings 16, multiple second into
Water hole 16 is connected to second chamber 14, and prevention is played the role of in the first inlet opening 15 and the second inlet opening 16, when outside moisture is logical
It crosses after the first inlet opening 15 entrance first chamber 13 or after outside moisture is by the second inlet opening 16 entrance second chamber 14, the
In one chamber 13 close to 15 position of the first inlet opening water-swellable material expand or second chamber 14 in close to second into
The water-swellable material of 16 position of water hole expands, so that rubber and foreign objects between first chamber 13 and the first sagittal plane
Extruding force between body sealing surface is bigger, between the rubber between second chamber 14 and the second sagittal plane and external object sealing surface
Extruding force it is bigger, prevention outside moisture passes through between the first sagittal plane and external object sealing surface or the first sagittal plane and extraneous
Enter in instrument between them impervious face.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
