Abstract
The utility model discloses an internal edge type sealing element which comprises a sealing element body. An annular protrusive edge strip which has a sealing function is arranged on the wall of a hole of the sealing element body. The internal edge type sealing element is reasonable in structure, good in elastic performance, capable of reducing friction with a sealed element, good in sealing performance and long in service life. Meanwhile, oil and water are not easy to leak, and the sealing element is beneficial for environmental protection.
Description
Technical field
The utility model relates to a kind of Sealing.
Background technique
Existing mechanical Sealing, the hole wall of its seal are smooth integral form, poor sealing performance, and easy oil leakage, with big by the friction of Sealing, working life is short, particularly the easy befouling environment of leakage of oil.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, good seal performance, and interior rib type Sealing little, long service life rubs.
Technical solution of the present utility model is:
Rib type Sealing in a kind of comprises seal body, it is characterized in that: the wall in the hole of seal body is provided with the convex annular rib that seals.
The convex annular rib has 1 or many.
The width of convex annular rib is 1/5 ~ 4/5 of hole wall width.
The end of seal body is round table-like.
The utility model is rational in infrastructure, and elastic performance is good, reduced with by the friction of Sealing, good seal performance, long service life, is leaked at not easy oil leakage, is conducive to environmental protection.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an embodiment's of the utility model structural representation.
Embodiment
Rib type Sealing in a kind of comprises seal body 1, and the wall in the hole 2 of seal body is provided with the convex annular rib 3 that seals.
The convex annular rib has 1 or many.
The overall width of convex annular rib is 1/5 ~ 4/5 of hole wall width.
The utility model can also have other suitable embodiments, and when routine Sealing as slurry pump used, it is round table-like that the end of seal body can be.
