Abstract
The invention discloses a sealing gasket, which comprises a rubber ring and a metal ring, wherein the metal ring is sheathed at the outer side of the rubber ring and is made of 45 steel, and a glue layer is arranged in a position between the rubber ring and the metal ring. According to a dustproof ring, the metal ring is sheathed at the outer side of the rubber ring, the metal ring realizes the support effect, the rubber ring realizes the sealing effect after being tightly pressed, through the dustproof ring, the sealing performance is better, the compression force is smaller during the connection, the born pressure is high, and meanwhile, a sealing groove is not needed. The dustproof ring adopting the structure has the advantages that the structure is simple, the work is stable and reliable, and the installation is convenient.
Description
Technical field
The present invention relates to a kind of seal washer.
Background technique
Be exposed at the dirts such as dust accompanying on the cylinder outer surface, sand-lime, rainwater and frost for removing the reciprocating piston bar, prevent that external dust, rainwater from entering sealing mechanism inside, this just needs a kind of seal washer.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiencies in the prior art, provides a kind of easy for installation, simple in structure, the reliable dust ring of working stability.
Technological scheme: in order to realize above purpose, a kind of seal washer of the present invention, it comprises: rubber ring and metal ring, the outside of described rubber ring is arranged with metal ring, the material of described metal ring is 45 steel, and in the middle of described rubber ring and metal ring, place is provided with glue layer.
Beneficial effect: a kind of seal washer of the present invention, by the sheathed metal ring in the outside at rubber ring, metal ring plays the effect of support, plays the effect of sealing after rubber ring is compacted, and this dust ring makes sealability better, during connection, impacting force is little, the pressure born is high, does not need to offer sealed groove, and the dust ring of this structure is simple in structure simultaneously, working stability is reliable, easy for installation.
The accompanying drawing explanation
Fig. 1 is the plan view that partly cuts open of the present invention;
Fig. 2 is scheme of installation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
As shown in Figure 1 and Figure 2, a kind of seal washer of the present invention, it comprises: rubber ring 1 and metal ring 2, the outside of described rubber ring 1 is arranged with metal ring 2, the material of described metal ring 2 is 45 steel, and in the middle of described rubber ring 1 and metal ring 2, place is provided with glue layer 3.
This dust ring is to be formed by metal ring 2 and rubber ring 1 gummed, install when of the present invention, cylindrical metal ring 2 is played a supporting role, play seal action after patio's rubber ring 1 is compacted, the good seal performance of this dust ring, when connecting, impacting force is little, bear pressure high, do not need to offer sealed groove, reduced the production technology cost.
Above-mentioned mode of execution is only explanation technical conceive of the present invention and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present invention enforcement according to this, can not limit the scope of the invention with this.All equivalents that Spirit Essence is made according to the present invention or modification, within all should being encompassed in protection scope of the present invention.
