Abstract
The utility model discloses a plane sealing gasket with a compensation function. The plane sealing gasket comprises a sealing gasket body (1); the two end surfaces of the sealing gasket body (1) are respectively provided with a plurality of convex ring-shaped sealing ribs (2); and the heights of at least two ring-shaped sealing ribs (2) are different from each other. The plane sealing gasket is good in sealing performance and avoids leakage.
Description
Technical field
The utility model relates to the mechanical sealing technology field, specifically is a kind of planar sealing pad with compensate function.
Background technique
At present, plane sealing is lined with the flat rubber sealing gasket of gum planar sealing pad and band metal frame, and this planar sealing pad upper and lower surfaces of existing technology is the plane or high annular seal muscle such as has; The upper and lower surfaces of the engineering goods assemblings back plane sealing gasket power that is squeezed relies on this extruding force that planar sealing pad is sealed the mechanical seal surface.Because all there is a certain size planeness in any mechanical surface; These planenesses cause the stressed size of the sealing surfaces of planar sealing pad uneven; Stressed too hour when a part of sealing surfaces of planar sealing pad, seepage will appear in this part sealing surfaces, causes sealing poor.
The model utility content
The technical problem that the utility model will solve is, overcomes the defective of above existing technology, and a kind of planar sealing pad of band compensate function of good seal performance is provided.
The technical solution of the utility model is; A kind of planar sealing pad with band compensate function of following structure is provided: it comprises the sealing gasket body; Be equipped with the annular seal muscle of evagination on the both ends of the surface of said sealing gasket body; Described annular seal muscle is many, and the height of at least two annular seal muscle is different.
After adopting above structure; The planar sealing pad of the utility model band compensate function compared with prior art; Have the following advantages: be equipped with the annular seal muscle of evagination on the both ends of the surface of this planar sealing pad, described annular seal muscle is many, and the height of at least two annular seal muscle is different.After this planar sealing pad is installed; Because planar sealing pad is squeezed; If when planeness not of uniform size appearred in the machinery part surface of installing relatively, the gap that mechanical parts sealing surfaces and sealing gasket match will be different, the zone that seal clearance the is little effect of being squeezed is big; The zone that seal clearance the is big effect of being squeezed is little; The higher big zone, annular seal muscle compensation sealing gap of the evagination height of planar sealing pad like this, the little zone, annular seal muscle compensation sealing gap that the evagination height is lower so just can guarantee that can both there be enough, stable sealing extruding force in each zone of planar sealing pad; Thereby make the good seal performance of planar sealing pad, especially can obtain good compensation sealing effect the not high part of machining accuracy; Even to the strict mechanical parts of seal request, many annular seal muscle can be set, make it reach good sealing effect.
As a kind of improvement, be connected with many connection sealed muscles spaced apart between every adjacent two annular seal muscle in said many annular seal muscle, the top of adjacent two the annular seal muscle with this in two ends of every connection sealed muscle is all equal.These many connection sealed muscles can prevent the seepage between the annular seal muscle of different heights, thereby have further guaranteed the sealability of whole mechanical sealing system.
As preferably, described annular seal muscle, connect sealed muscle and the sealing gasket body is an one compression molding structure.
Said annular seal muscle can be semicircle with the cross section that is connected sealed muscle, triangle, rectangle and trapezoidal etc.
Said sealing gasket body can be rubber body, plastics and other material etc.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Embodiment one, and is as depicted in figs. 1 and 2:
The planar sealing pad of the utility model band compensate function, it comprises sealing gasket body 1, is equipped with the annular seal muscle 2 of evagination on the both ends of the surface of said sealing gasket body 1, described annular seal muscle 2 is many, and the height of at least two annular seal muscle 2 is different.
Be connected with many connection sealed muscles 3 spaced apart between every adjacent two annular seal muscle 2 in said many annular seal muscle 2, the top of adjacent two the annular seal muscle 2 with this in two ends of every connection sealed muscle 3 is all equal.
The annular seal muscle 2 of present embodiment is two, and the height of two annular seal muscle 2 is different.
Described annular seal muscle 2, connect sealed muscle 3 and sealing gasket body 1 is an one compression molding structure.
Embodiment two, like Fig. 3 and shown in Figure 4:
The planar sealing pad of the utility model band compensate function; It comprises metal frame 4 and sealing gasket body 1; Said sealing gasket body 1 close-fitting is on metal frame 4; Be equipped with the annular seal muscle 2 of evagination on the both ends of the surface of said sealing gasket body 1, described annular seal muscle 2 is many, and the height of at least two annular seal muscle 2 is different.
Be connected with many connection sealed muscles 3 spaced apart between every adjacent two annular seal muscle 2, the top of adjacent two the annular seal muscle 2 with this in two ends of every connection sealed muscle 3 is all equal.
The annular seal muscle 2 of present embodiment is two, and the height of two annular seal muscle 2 is different.
Described annular seal muscle 2, connect sealed muscle 3 and sealing gasket body 1 is an one compression molding structure.
Embodiment three, like Fig. 5, Fig. 6 and shown in Figure 7:
The annular seal muscle 2 of present embodiment is four, and the height of at least two annular seal muscle 2 is different.
