Abstract
The utility model discloses a self-compensating seal ring, which comprises a clamping strip, wherein two ring bodies are arranged in the clamping strip; opposite faces of the two ring bodies are respectively provided with a bevel edge; a distance of openings of the two bevel edges is larger than a distance of inner parts of the two bevel edges; and a sealing strip with a section being in a triangular shape is arranged between the two ring bodies, and is matched with the bevel edges. The self-compensating seal ring has the beneficial effects that since the structure is adopted, when being installed, the seal ring is squeezed through two sides, inwards force of the ring bodies are turned into inwards thrust to the sealing strip through the bevel edges, so that a long-term seal function is realized, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of auto-compensating seal ring.
Background technique
The structural type of seal ring is of all kinds, and common O RunddichtringO is a kind of seal ring of ring-shaped section and ring-shaped, and it is simple in structure, and easy for installation, therefore is widely used in being tightly connected of various device.In long-term using process, keep away distortion is followed the string owing to the O RunddichtringO, can not keep good sealing effect for a long time, influence working life.
Summary of the invention
The O RunddichtringO uses sealing effect bad for a long time in the prior art in order to solve in the present invention, and a kind of auto-compensating seal ring of long service life is provided.
For achieving the above object, the present invention adopts following technical proposals:
A kind of auto-compensating seal ring comprises card article, is provided with two circle bodies in the card article, two circle body opposing sides all have hypotenuse, this two hypotenuse is provided with cross section Stamping Steel Ribbon triangular in shape in the distance at its edge distance greater than inside between two circle bodies, the sealing bar matches with described hypotenuse.
The distance of described two hypotenuses at its edge is 2-3mm.
The beneficial effects of the utility model are, adopt said structure by both sides seal ring to be pushed when mounted, and circle body is converted into the inside thrust of Stamping Steel Ribbon through hypotenuse to the power of introversion, thereby plays long-time seal action, reaches the effect that prolong working life.
Description of drawings
Fig. 1 is structural representation of the present invention.
Wherein, 1. card article, 2. circle body, 3. Stamping Steel Ribbon.
Embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of auto-compensating seal ring, comprise card article 1, be provided with two circle bodies 2 in the card article 1, two circle body 2 opposing sides all have hypotenuse, this two hypotenuse is provided with cross section Stamping Steel Ribbon triangular in shape 3 in the distance at its edge distance greater than inside between two circle bodies 2, sealing bar 3 matches with described hypotenuse.
The distance of described two hypotenuses at its edge is 2-3mm.
