Abstract
The utility model discloses a butterfly sealing ring. The middle of the outer surface of the sealing ring is provided with a flange; the cross section shape of the flange is rectangular. In the whole sealing process, because of the generation of the flange, the flange can bear part of pressure when the pressure is large, which plays favorable sealing action on products. The flange part shares part of pressure to make sealing elements not generate larger pressure, which can prevent the sealing elements aging. Because of the generation of the flange part, the amount of compression of the sealing elements can be mastered from the measurable altitude variation of the outer surface; consequently, the sealing elements are in favorable sealing state.
Description
The utility model relates to a kind of Sealing.
In the prior art, the sectional shape of traditional rubber-like Sealing generally all is circle or semicircular, and its sealing contact surface is smaller, so its pressure is also just bigger, causes distortion of materials destruction and aging easily, causes seepage; And when its pressure is too small, equally also cause seepage easily.
The purpose of this utility model is: a kind of butterfly seal ring is provided, and its existing better seal performance is not easy again to cause the destruction of material and wear out.
The technical solution of the utility model is: a kind of butterfly seal ring, the centre of the outer surface of described seal ring is provided with flange.
The further technological scheme of the utility model is: a kind of butterfly seal ring, and the centre of the outer surface of described seal ring is provided with flange, and the sectional shape of described flange is a rectangle.
The utility model has the advantages that:
1. in whole seal process, because the generation of flange, when pressure was big, flange can be born part pressure, and makes product play good seal action.
2. part pressure is shared at the flange position, and makes Sealing can not produce big pressure, can prevent the aging of Sealing.
3. owing to the generation of flange portion, from the variable height that outer surface can be surveyed, can grasp the Sealing decrement, thereby be in good sealing state.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Wherein: 1. outer surface; 2. flange; 3. internal surface.
Embodiment: a kind of butterfly seal ring, the centre of the outer surface 1 of described seal ring is provided with flange 2; The sectional shape of described flange 2 is a rectangle.In whole seal process, because the generation of flange 2, when pressure was big, flange 2 can be born part pressure, and makes product play good seal action; Part pressure is shared at flange 2 positions, and makes Sealing can not produce big pressure, can prevent the aging of Sealing; Because the generation of flange 2 parts from the variable height that outer surface 1 can be surveyed, can be grasped the Sealing decrement, thereby be in good sealing state.
Claims (2)
1. butterfly seal ring, it is characterized in that: the centre of the outer surface of described seal ring (1) is provided with flange (2).
2. a kind of butterfly seal ring according to claim 1 is characterized in that: the sectional shape of described flange (2) is a rectangle.
