Abstract
The utility model provides a sealing gasket including an annular skeleton and a flexibility body on the stand Skeleton. The skeleton and the flexibility body forms a '0' font style or a rectangle. The skeleton in thickness of 0.8-1mm is made of stainless steal. The flexibility body in thickness of 0.8mm is made by black lead with a purity >= 99%. The flexibility body is stuck to the upside surface and the downside surface of the skeleton by glue. Ton the upside and the downside surface of the annular edge of the skeleton are provided with 3-5 strips of tooth ripple. The utility model has the advantages that it has a great seal because the tooth ripple at the sealing surface makes decks of sealing ring are formed around the sealed window and it can prevent the high-pressure medium from leaking for its reliable seal.
Description
Technical field
The utility model relates to equipment component, is specifically related to a kind of sealing gasket.
Background technique
When measuring steam boiler or other pressurized container water level, window formula fluviograph window place uses a kind of Sealing.It is between metal table body sealing surface and the sheet mica, and the metal backup shoe that studs with high-strength glass is pressed on the sheet mica by bolt, and the effect of sealing gasket mainly is to prevent the high-pressure medium leakage.Existing sealing gasket product mainly adopts the thick stainless steel sheets of 0.15-0.2mm to do skeleton, the surface has plenty of smooth surface, have plenty of going out big circle or square aperture about many densely covered 1mm on the stainless steel sheets, then, adhere to certain thickness Expanded graphite on the two sides of steel disc.The weak spot of sealing surface appears in this plain cushion and mesh pad easily, causes leakage phenomenon especially easily.
The model utility content
The purpose of this utility model is to overcome the various defectives of traditional product, and a kind of reliable, as can effectively to prevent high-pressure medium generation leakage sealing gasket that seals is provided.
For achieving the above object, the utility model provides sealing gasket, comprise the skeleton of annular and be positioned at flexible body on the skeleton, the upper and lower surface of skeleton annular peripheral edge portion is provided with the tooth ripple of symmetry, flexible body be positioned on the upper and lower surface of skeleton and with skeletal fixation together.
The utility model sealing gasket, wherein said skeleton and flexible body are " 0 " font or rectangle, and skeleton thickness is 0.8-1mm, and flexible body thickness is 0.8mm.
The utility model sealing gasket, wherein said skeleton adopt corrosion resistant plate to make, and described flexible body adopts the graphite of purity 〉=99% to make.
The utility model sealing gasket, wherein said flexible body adopts gluing being connected on the skeleton.
The utility model sealing gasket, wherein said tooth ripple are the 3-5 bar.
The advantage of the utility model sealing gasket is: it is by being located at the tooth ripple at sealing surface place, round sealed window, form seal ring in layer, thereby played good seal action, its sealing is reliable, can prevent effectively that high-pressure medium from revealing.
Description of drawings
Fig. 1 is the plan view of the utility model sealing gasket;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model sealing gasket comprises annular skeleton 1 and the flexible body 2 that is positioned on the skeleton 1, and skeleton 1 and flexible body 2 are " 0 " font, and skeleton 1 thickness is 0.8-1mm, and flexible body 2 thickness are 0.8mm.Skeleton 1 adopts corrosion resistant plate to make, and flexible body 2 adopts the graphite of purity 〉=99% to make.Flexible body 2 is positioned on the skeleton 1 upper and lower surface, adopts gluing being connected on the skeleton 1.The upper and lower surface of skeleton 1 outer circular edge part is provided with the tooth ripple 3 of 3-5 bar symmetry.
In other embodiments of the utility model sealing gasket, skeleton 1 and flexible body 2 are rectangular.
Owing to be located at the effect of the tooth ripple 3 at sealing surface place, round sealed window, form seal ring in layer, thereby played good seal action, its sealing is reliable, can prevent effectively that high-pressure medium from revealing.
