Description

Ripple type cladding pad

Technical field

The utility model relates to a kind of metallic cover pad more particularly to a kind of cladding pads with ripple type.

Background technique

Flange-gasket-bolt combined connecting structure is a kind of industrial applications such as machinery, petroleum, chemical industry most widely pipe Road connection type.The primary element that it is connected as pipeline, accounts for highly important status, it both ensure that in modern industry The connection and sealing of pipeline and pipeline, pipeline and equipment room, and facilitate dismounting of the pipeline in construction, installation, maintenance.Gasket Sealing be flanged joint core, be reinforced gasket sealing performance, ripple type packet is added usually between gasket and connector Pad is covered, Chinese utility model " the ripple cladding of a such as patent No. ZL201120476724.5 (notification number CN202327081U) Gasket " it discloses a kind of gasket, especially a kind of corrugated jacket gasket, by gasket shell, wavy metal collet, corrugated Filler and expanded graphite meterial composition, the two sides of wavy metal collet are equipped with corrugated filled layer, corrugated filled layer it is outer Side is equipped with expanded graphite layer, and the outside of expanded graphite layer is equipped with gasket shell, which has particularly excellent close Feng Xing has good resilience and can keep excellent sealing performance for a long time, and has very high security reliability, finally also It can be reduced the friction between metal material, alleviate gasket deformation, but the expanded graphite layer of its auxiliary is with graphite and viscous on a small quantity Mixture is pressed into through mixing, and structure is more open, there is the shortcomings that graphite linings are easily washed loss in use.Therefore It needs to coat pad to existing ripple type and be improved further.

Summary of the invention

Technical problem to be solved in the utility model is to provide one kind for above-mentioned state of the art and be not easy to be squeezed The ripple type of pressure sliding deformation coats pad.

Technical solution adopted by the utility model to solve the above technical problems is as follows: ripple type cladding pad, includes pad The sealing surface of piece ontology, the shim body upper and lower surfaces is corrugated, it is characterised in that: if the shim body includes Alternately winding is arranged and in the metal tape of undaform and filler material band and filler material band dried layer, and the filler material band includes stacking The graphite encapsulation layer of inner ring and the mica positioned at inner ring periphery and/or fiberglass sealed layer be set, and the inner ring Support ring is additionally provided between graphite encapsulation layer and mica and/or fiberglass sealed layer positioned at inner ring periphery.

Further, the support ring is V-type support ring.The branch in shim body since ripple type cladding pad is arranged in The angle of pushing out ring is set as 80~85 °, to increase extension space of the support ring in pressurized process, increases compression row Journey prevents supporting steel band from easily falling apart under impact, pressure vibration and playing the role of better seal, while V-type supporting steel band is excellent Selection of land is set as the more V-types in broadband, that is, has adjusted the thickness and width of support ring, can greatly improve the bearing capacity of support ring, resist Deformability and supporting area, at the same also add inner ring graphite encapsulation layer and positioned at inner ring periphery mica and/or Intensity between fiberglass sealed layer.

Further, in order to significantly improve the antiscour intensity of ripple type cladding pad, on the sealing surface and/or it It is arranged with bound edge, the bound edge makes the shim body have sandwich.

In order to keep out various etching chemicals fluid highly basic, hydrochloric acid, the erosion of the strongly corrosion liquids such as sulfuric acid, into One step, the bound edge can be selected from any one following material tinplate, austenitic stainless steel 304 or austenitic stainless steel 316.

Compared with prior art, the utility model has the advantage of ripple type coat pad using close to outer ring mica and/ Or fiberglass sealed layer and the graphite encapsulation layer close to inner ring, graphite can be resistant to high temperature, meanwhile, the upper and lower table of shim body The sealing surface in face and metal tape in undaform, increase extension space of the support ring in pressurized process jointly, to realize Ripple type cladding pad is not easy to be extruded sliding deformation, feature finally strong using the rigidity of mica and/or fiberglass sealed layer, It is disposed at close to outer ring, so that the ripple type after preparation coats pad and also assures while guaranteeing that heat resistance improves easily clearly Clean property, while the setting of support ring effectively improves the whole anti-extrusion intensity of ripple type cladding pad.

Fig. 2 is the structural schematic diagram of the V-type supporting steel band in Fig. 1.

Specific embodiment

The utility model is described in further detail below in conjunction with figure embodiment.

It as illustrated in fig. 1 and 2, is the most preferred embodiment of the utility model.Ripple type in the present embodiment coats pad, includes The sealing surface 11 of shim body 1,1 upper and lower surfaces of shim body is corrugated, and shim body 1 includes that several layers are alternately wound It is arranged and is in the metal tape 2 and filler material band of undaform, the sealing surface of 1 upper and lower surfaces of shim body and the gold in undaform Belong to band 2, increase extension space of the support ring 5 in pressurized process jointly, to realize that ripple type cladding pad is not easy to be extruded cunning Dynamic deformation, and filler material band includes being stacked the graphite encapsulation layer 3 in inner ring and the mica and/or glass positioned at inner ring periphery Glass fibrous encapsulation layer 4, the present embodiment be unfolded for only having fiberglass sealed layer 4 explanation, and the graphite encapsulation layer 3 of inner ring with Support ring 5 is additionally provided between the fiberglass sealed layer 4 of inner ring periphery, ripple type cladding pad is using the glass close to outer ring The graphite encapsulation layer 3 of glass fibrous encapsulation layer 4 and close inner ring, graphite can be resistant to high temperature, meanwhile, utilize fiberglass sealed layer The strong feature of 4 rigidity is disposed at close to outer ring, so that the ripple type cladding pad after preparation is guaranteeing what heat resistance improved Property easy to clean is also assured simultaneously, while the setting of support ring 5 effectively improves the whole anti-extrusion intensity of ripple type cladding pad. Wherein, support ring is V-type support ring, and V-type support ring is set as the more V-types in broadband, and the angle [alpha] of the V-type is 80~85 °.Due to setting The angle of support ring set in the shim body 1 of ripple type cladding pad is set as 80~85 °, thus increase support ring by Extension space during pressure, increases compression stroke, prevents supporting steel band from easily falling apart and being played more under impact, pressure vibration Good sealing function, while V-type supporting steel band is set as the more V-types in broadband, that is, has adjusted the thickness and width of support ring 5, it can be big Big bearing capacity, non-deformability and the supporting area for improving support ring 5, while also adding the graphite encapsulation layer 3 of inner ring And the intensity between the mica and/or fiberglass sealed layer 4 positioned at inner ring periphery.Preferably, in order to significantly improve ripple Type coats the antiscour intensity of pad, and bound edge 12 is provided with above and below sealing surface 11, and bound edge makes shim body 1 have folder Layer structure, in order to keep out various etching chemicals fluid highly basic, hydrochloric acid, the erosion of the strongly corrosion liquids such as sulfuric acid, packet Side 12 can be selected from any one material in tinplate, austenitic stainless steel 304 or austenitic stainless steel 316.
