Abstract
The utility model relates to an annular seal device, comprising an outer ring and a projection disposed on the inner side of the outer ring. The projection has a circular section. The annular seal device is disposed on a rotor body of a centrifugal machine, and thus has a relatively fixed position and will not fall off frequently because of repeated opening of a rotor cap during use. The projection disposed in an inner ring has commendable buffering and sealing effect.
Description
Technical field
The utility model relates to a kind of annular seal, particularly a kind of annular seal that is used for centrifuge.
Background technique
No matter medical treatment, pharmacy relevant industries are non-sterile environment of requirement or gnotobasis with centrifuge; In its using process very high requirement has been proposed environment requirement; Under high-grade environmental requirement; Such as in sterile workshop, workshops such as ten thousand grades, 100,000 grades are just arranged, good airtight performance can make outside isolation of remaining valid with machine intimate.Solid, liquid, gas in the centrifuge rotor must not produce cross pollution with operator, external environment condition mutually.
And more common at present seal arrangement is that elastomeric O-rings shape seal arrangement is housed on rotor cover, because annular seal is mounted on the rotor cover, is to install downwards, is easy to cause coming off of annular seal.
The model utility content
The purpose of the utility model is to provide a kind of difficult drop-off, it is convenient to install and can increase the annular seal in working life.
The utility model annular seal comprises: the outer ring; Projection is arranged on the inboard of said outer ring.The cross section of said projection is circular.
The utility model annular seal is arranged on the rotor body of centrifuge; Make its position relative fixed that just becomes; Can be owing to rotor cover opening repeatedly in use do not caused the phenomenon that constantly comes off, and the projection that is arranged on inner ring can open the effect of good buffering and sealing.
Description of drawings
Fig. 1 is the utility model annular seal sectional view.
Description of reference numerals in the utility model annular seal accompanying drawing:
1-outer ring 2-projection
Embodiment
Below in conjunction with accompanying drawing the utility model annular seal is done further explain.
As shown in Figure 1, the utility model annular seal comprises: outer ring 1; Projection 2 is arranged on the inboard of outer ring 1.The cross section of projection 2 is circular.
In use, rotor cover presses down, and when rotor cover touched projection, 2 pairs of rotor cover of projection produced good buffer function.And the material of annular seal is flexible material, can adjust accordingly from action according to the different shape of rotor cover, can carry out well fixing to rotor cover, also can play a very good protection to rotor cover simultaneously.
The preferred embodiment of below the utility model having been created specifies; But the utility model is created and is not limited to said embodiment; Those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the invention spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
