Abstract
The utility model discloses a kind of metal-clad pad, comprise a metallic shim and cladding, four sides of metallic shim are enclosed with cladding, metallic shim one side is circular arc, metallic shim two parallel surfaces centers offer ellipse hole, through-hole wall is provided with from the extended one supporting leg of metallic shim, and metallic shim one surface is provided with two along the sealing gear ring at through hole edge.Cladding is that expanded graphite or stuffing asbestos are made.The outer lateral section of metallic shim is the arc that concaves.The utility model is rational in infrastructure, not perishable, and while being connected with flange slot due to non-metallic pad, non-metallic pad can be filled up the gap in connection, prevents the leakage of liquid, gas.
Description
Technical field
The utility model belongs to pipe fittings field, is specifically related to a kind of metal-clad pad.
Background technique
Metallic shim is mainly used in and being connected of flange, it be shaped as circle or ellipse, when pad contacts with the outer side surface of flange slot, under the effect of impacting force, pad can deform and form radially self-packing effect.Under the impact of environment, particularly at chemical field, metallic shim easily corrodes around, and seal of vessel is affected, and makes its function that loses pad, thereby has influence on the running of whole machinery equipment.
Model utility content
The utility model is intended to overcome the defect of prior art, and a kind of metal-clad pad is provided, possess rational in infrastructure, good airproof performance, uncorruptible feature.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
A kind of metal-clad pad, comprise a metallic shim and cladding, four sides of metallic shim are enclosed with cladding, metallic shim one side is circular arc, metallic shim two parallel surfaces centers offer ellipse hole, through-hole wall is provided with from the extended one supporting leg of metallic shim, and metallic shim one surface is provided with two along the sealing gear ring at through hole edge.
Further, cladding is that expanded graphite or stuffing asbestos are made.
Further, the outer lateral section of metallic shim is the arc that concaves.
Compared with prior art, the utlity model has following beneficial effect:
The utility model is for boats and ships, oil refining pipeline and various kinds of equipment flange connections static seal, it is rational in infrastructure, not perishable, while being connected with flange slot due to non-metallic pad, non-metallic pad can be filled up the gap in connection, greatly improve the sealing of flange and container, prevented the leakage of liquid, gas.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model metal-clad pad;
Fig. 2 is the schematic cross-section of the utility model metal-clad pad.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figure 1 and Figure 2, a kind of metal-clad pad, comprises a metallic shim 1 and cladding 2, and 1 four sides of metallic shim are enclosed with cladding 2, and cladding is that expanded graphite or stuffing asbestos are made.The outer lateral section of metallic shim is the arc that concaves.Metallic shim 1 one sides are circular arc, and metallic shim two parallel surfaces centers offer ellipse hole 5, and through-hole wall is provided with from the extended one supporting leg 3 of metallic shim, and metallic shim one surface is provided with two along the sealing gear ring 4 at through hole edge.
The utility model is for boats and ships, oil refining pipeline and various kinds of equipment flange connections static seal, it is rational in infrastructure, not perishable, while being connected with flange slot due to non-metallic pad, non-metallic pad can be filled up the gap in connection, greatly improve the sealing of flange and container, prevented the leakage of liquid, gas.
The foregoing is only explanation mode of execution of the present utility model; be not limited to the utility model; for a person skilled in the art; all within spirit of the present utility model and principle; any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
