Abstract
The utility model discloses a sealing gasket, which can acquire good sealing effect in a low pressure environment and comprises a gasket body made of elastic materials. The cross section of the gasket body is annular. In addition, a gasket fastening structure is connected to the side wall of the gasket body and provided with a bolt through hole, and the axial direction of the bolt through hole is parallel to the axial direction of the gasket body. The cross section of the gasket body is annular, thereby enabling the gasket body to have large deformation under the effect of small pressure. Furthermore, due to the fact that the gasket body is made of the elastic materials, the gasket body has the ability of restoring deformation. Therefore, the upper surface and the lower surface of the gasket body can be tightly attached to the upper surface and the lower surface of the gap to be sealed respectively, and the gap is well sealed. In addition, by means of arrangement of the gasket fastening structure, the gasket body is attached to the upper surface and the lower surface of the gap more tightly through structures such as a stud and the like, and the sealing effect is better.
Description
Technical field
The utility model relates to a kind of seal washer that the slit is sealed of being used for.
Background technique
Seal washer is generally processed by elastic material; Rubber material etc. for example; And comprise a ring washer body, the cross section of packing ring body is generally solid rectangle, and this seal washer in use; The upper surface of packing ring body and lower surface and need sealing the slit upper surface and lower surface contact defective tightness; Especially component are under the lower environment of packing ring body applied pressure, and the upper surface of packing ring body and lower surface exist than big gap respectively and between the upper surface in the slit of needs sealing and the lower surface, and this just makes that seal washer can't be to above-mentioned slit better seal.
The model utility content
The technical problem that the utility model solves provides a kind of sealing effect better seal packing ring.
The utility model solves the technological scheme that its technical problem adopted: seal washer, comprise the packing ring body of processing by elastic material, and the cross section of said packing ring body is an annular.
Further be: be connected with the packing ring fastening structure on the sidewall of said packing ring body, said packing ring fastening structure is provided with bolt hole, the parallel to an axis of the axial and packing ring body of said bolt hole.
Further be: the cross section of said packing ring body is a ring.
The beneficial effect of the utility model is: because the cross section of packing ring body is annular; Make the packing ring body stand under the less pressure effect moderate finite deformation to take place; Process by elastic material owing to the packing ring body again; Therefore have the answer deformation ability, this just makes upper surface and the lower surface of packing ring body can fit tightly with the upper surface and the lower surface in the slit of needs sealing respectively, to slit realization better seal.In addition, through the packing ring fastening structure is set, can make the upper surface and the lower surface joint more compact in packing ring body and slit through structures such as bolts, sealing effect is better.
Description of drawings
Fig. 1 is the schematic representation of cross section that has the packing ring body of packing ring fastening structure;
Fig. 2 is for being provided with the schematic representation of the seal washer of the utility model in the slit of needs sealing.
Be labeled as among the figure: 1-packing ring body, 2-cavity, 3-bolt hole, 4-packing ring fastening structure, 5-upper surface, 6-lower surface, 7-bolt, 8-slit.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As depicted in figs. 1 and 2, seal washer comprises the packing ring body of being processed by elastic material 1, and the cross section of said packing ring body 1 is an annular.The cross section of above-mentioned packing ring body 1 can be the annular shape in side; Be preferably ring; Because of the cross section of ring has the upper surface and the lower surface of evagination, so more help after the packing ring body distortion and the upper surface in the slit of needs sealing and lower surface between fit tightly.The cross section of above-mentioned packing ring body 1 is owing to be annular; Make the inside of packing ring body 1 have the cavity 2 of an annular; This cavity can be convenient to packing ring body 1 extrusion-deformation takes place when receiving external pressure; Deformation degree of extrusion is big more, and the answer deformability that packing ring body 1 has is big more, and is tight more with the lower surface applying with the upper surface in the slit of needs sealings.
In order to improve sealing effect, be connected with packing ring fastening structure 4 on the sidewall of said packing ring body 1, said packing ring fastening structure 4 is provided with bolt hole 3, the parallel to an axis of the axial and packing ring body 1 of said bolt hole 3.As shown in Figure 2, during use, the seal washer of the utility model is placed in the slit 8 that needs sealing; Through bolt 7 packing ring body 1 is compressed, make 1 extrusion-deformation of packing ring body extremely at utmost, at this moment; The restoring force that packing ring body 1 has is also maximum; Therefore, packing ring body 1 can be realized very fitting closely with lower surface 6 with the upper surface 5 in slit 8, can above-mentioned slit 8 effectively be sealed.
Claims (3)
1. seal washer comprises the packing ring body of being processed by elastic material (1), it is characterized in that: the cross section of said packing ring body (1) is annular.
2. seal washer as claimed in claim 1; It is characterized in that: be connected with packing ring fastening structure (4) on the sidewall of said packing ring body (1); Said packing ring fastening structure (4) is provided with bolt hole (3), the parallel to an axis of the axial and packing ring body (1) of said bolt hole (3).
3. according to claim 1 or claim 2 seal washer, it is characterized in that: the cross section of said packing ring body (1) is a ring.
