Abstract
The utility model belongs to a sealing device, in particular relates to a sealing washer, which overcomes the defects that the existing sealing washers are easy to break under high extrusion pressure. The sealing device comprises a framework and a rubber body; the internal surface of the framework is connected with the rubber body, wherein the surface of the outer ring of the rubber body is connected with the framework, and the corresponding central part of the surface of the inner ring is provided with an annular recess. The sealing device improves the state of the sealing washer after compression, thereby effectively preventing the washer from breaking, and improving the sealing effect of the sealing ring.
Description
Technical field
The utility model belongs to seal arrangement, relates in particular to a kind of seal washer.
Background technique
In the prior art commonly used gasket structure as shown in Figure 1, this packing ring is made up of skeleton 1 and rubber body 2, skeleton 1 and rubber body 2 are sulfided into one, utilize the interference fit between rubber body 2 and the contact component, make packing ring play seal action.But as shown in the figure, the side that seals on the rubber body is solid shape, after rubber body is subjected to bigger extruding force, can produce bigger distortion, and solid rubber body does not provide the space that discharges distortion for its distortion, therefore very easily causes the breakage of packing ring, causes seal failure.
Summary of the invention
The purpose of this utility model is to overcome the defective of existing seal washer cracky under bigger extruding force effect, and the state that it has improved after the seal washer compression prevents the packing ring breakage effectively, has improved the sealing effect of packing ring.
The utility model is to adopt following technological scheme to realize: a kind of seal washer, comprise skeleton and rubber body, the internal surface of skeleton is connected with rubber body, wherein, the surface, outer ring of described rubber body is connected with skeleton, and the center portion of corresponding inner peripheral surface is provided with annular groove.
In the utility model, described groove sectional shape can be arc, semicircle, triangle, waveform or polygonal.When rubber body was subjected to bigger extruding force compressive strain, this annular groove made product can not crushed damage for its distortion provides Free up Memory, has guaranteed the sealing effect of packing ring.In addition, after inner peripheral surface was provided with groove, inner peripheral surface was separated into up and down two-part, is equivalent to be interference fit between two seal lips and the contact component, has improved sealing effect, and and contact component between servo-actuated good.
The beneficial effects of the utility model are: by on the inner peripheral surface of rubber body annular groove being set, for the compressive strain of rubber body provides Free up Memory, improve the state after the packing ring compression, it is damaged to prevent that it from producing, and has improved the sealing effect of packing ring.
Description of drawings
Fig. 1 is the sectional view of seal washer in the prior art;
Fig. 2 is the sectional view of seal washer in the utility model.
Embodiment
As shown in Figure 2, seal washer is made up of skeleton 1 and rubber body 2, the surface, outer ring of rubber body 2 is connected with skeleton 1, the center portion of its inner peripheral surface is provided with annular groove 3, this groove provides Free up Memory for the compressive strain of rubber body 2, be difficult for badly when making packing ring be subjected to bigger extruding force, guaranteed the sealing effect and the working life of packing ring by crushing.In addition, groove 3 makes and has formed two surface of contact 4 and 5 between rubber body 2 and the contact component, these two surface of contact are equivalent to two seal lips, rubber body by surface of contact 4 and 5 and contact component between be interference fit, servo-actuated between packing ring and the contact component is better, has improved the sealing effect of packing ring.
As shown in Figure 2, the sectional shape semicircular in shape of groove 3, in addition, the sectional shape of groove 3 also can be arc, triangle, quadrilateral, waveform or other polygonal shapes.
Claims (5)
1. a seal washer comprises skeleton and rubber body, and the internal surface of skeleton is connected with rubber body, it is characterized in that: the surface, outer ring of described rubber body is connected with skeleton, and the center portion of corresponding inner peripheral surface is provided with annular groove.
