CN203384366U - Improved sealing gasket - Google Patents

Abstract

The utility model relates to an improved sealing gasket. The improved sealing gasket comprises a gasket body. A through hole is formed in the middle of the gasket body for forming the annular sealing gasket, the annular sealing gasket is provided with a plurality of blind holes, the sections of the blind holes are square, the depth of the blind holes is one sixth that of the gasket body, and the blind holes are uniformly formed in the gasket body in the circumferential direction. According to the improved sealing gasket, the blind holes are formed, and therefore stress concentration is reduced and sealing oil is prevented from staining the sealing gasket.

Description

A kind of modified model sealing gasket

Technical field

The utility model relates to the sealed product technical field, relates in particular to a kind of modified model sealing gasket.

Background technique

Now in machinery, the copper sealing gasket between link mainly contains two kinds of conventional seals pad and composite pads, the periphery of these two kinds of sealing gaskets is plane, when carrying out end face seal, groove or the corner angle of fixing seal pad need to be set on part, otherwise sealing gasket is difficult for fixing.But this method fixing seal pad exists sealing gasket to produce stress owing to applying larger torque and concentrates, because sealing gasket is fixed in groove or corner angle, the distortion that stress produces can't be discharged, and causes the damage of sealing gasket, seal fluid simultaneously and assemble the lower surface of middle sealing gasket, cause stained.

The model utility content

The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of modified model sealing gasket is provided.

The utility model is to be achieved through the following technical solutions:

A kind of modified model sealing gasket, comprise the packing ring body, and the centre of described packing ring body has through hole to form cyclic sealing gasket, and described annular seal packing ring body is provided with a plurality of blind holes.

As optimal technical scheme of the present utility model, the cross section of described blind hole is square.

As optimal technical scheme of the present utility model, the sixth that the degree of depth of described blind hole is the packing ring body.

As optimal technical scheme of the present utility model, the quantity of described blind hole is six.

As optimal technical scheme of the present utility model, described blind hole is along circumferentially being evenly distributed on the packing ring body.

Compared with prior art, the beneficial effects of the utility model are: the utility model is by arranging blind hole, reduces stress and avoids sealing the stained sealing gasket of fluid concentrated the time.

The accompanying drawing explanation

Fig. 1 is plan view of the present utility model;

Fig. 2 is the A-A sectional view in Fig. 1.

Embodiment

In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

Refer to Fig. 1 and Fig. 2, Fig. 1 is plan view of the present utility model, and Fig. 2 is the A-A sectional view in Fig. 1.

Described a kind of modified model sealing gasket, comprisepacking ring body 1, and the centre of describedpacking ring body 1 has throughhole 2 to form cyclic sealing gasket, and described annular sealpacking ring body 1 is provided with a plurality ofblind holes 3, reduces stress and avoid sealing the stained sealing gasket of fluid concentrated the time.

The cross section of describedblind hole 3 is square, the sixth that the degree of depth of describedblind hole 3 is packingring body 1.

The quantity of describedblind hole 3 is six, and describedblind hole 3 is along circumferentially being evenly distributed onpacking ring body 1.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
