Abstract
The utility model discloses an ultra-high-temperature and ultra-high-pressure sealing washer formed by combining metal and expanded graphite. The sealing washer comprises more than two expanded graphite washers, wherein a metal wire mesh is sandwiched between every two expanded graphite washers; and a metal ring with a turned edge is coated outside one face of the outermost expanded graphite washer. The sealing washer is applicable to connection sealing of various kinds of high-temperature and high-pressure equipment end ports; after the ports are connected, the expanded graphite washers are in a metal closed encirclement ring which is formed by one face of each end port and the metal ring with the turned edge; and if sealing of the expanded graphite washers on connection equipment fails due to ultra-high temperature and ultra-high pressure, the expanded graphite washers are in the metal closed encirclement ring and cannot be leaked, so the outer parts of the expanded graphite washers can be effectively contacted with a seal part, and requirements for sealing are met.
Description
Technical field
The utility model relates to a kind of Sealing, is specifically related to a kind of High Pressure Seal Washer that is used for the chemical industry place.
Background technique
Sealing gasket is a kind of application seal element very widely; The effect of sealing gasket be by sealing material for the contact pressure of engaging surface and for the elastic-restoring force of fastening external force form jointly the interior media blocking effect is formed sealing, prevent that junction plane from must leak.
Sealing gasket be divided into nonmetal sealing gasket nonmetal with metallic combination sealing gasket and metallic gasket three major types, its material is common has rubber, leather, asbestos slate, cork, teflon, galvanized iron, steel, aluminium, copper and stainless steel etc.Selecting for use of sealing gasket generally is according to working pressure, operating temperature, and the form of the corrosivity of sealing medium and combination seal face is selected for use.In general, when normal temperature low pressure, select nonmetal soft sweet sealing gasket for use; During super pressure-high temperature, select metal and nonmetal combination seal pad or metallic gasket for use; In temperature, when pressure has bigger fluctuation, select for use good springiness or the self-energized seal pad; At low temperature, under Korrosionsmedium or the vacuum condition, considered has the sealing gasket of property.
Now generally when high temperature, high pressure sealing majority select Expanded Graphite Sealing Materials for use; Expanded graphite is that a kind of method of physics or chemistry of utilizing makes non-carbonaceous reactant insert graphite layers, has kept the crystalline compounds of graphite laminate structure when closing with the plain hexagonal network planar junction of charcoal again.It not only keeps the excellent physicochemical property of graphite, and because the interaction of insertion material and graphite layer demonstrates the new capability that original graphite and intercalated material do not possess.The graphite that is inserted with intercalation compound is when running into high temperature; Intercalation compound will decompose; Produce a kind ofly along the axial thrust of graphite layers C, this thrust is much larger than the interlayer combination force of graphite particle, and graphite layers is open under the effect of this thrust; Thereby graphite particle is expanded along C axle direction high power ground, form vermiform expanded graphite.Can " embedding " go into chemical substance and have expansiveness between graphite layer and the layer.Expanded graphite, its specific surface is very big, and surface energy is very high; Adsorption force is very strong, can not add any binder, directly under pressure; Relying on the mutual absorption and chimeric and combine of self, thereby be processed into the goods of different shape easily, is present a kind of maximum HTHP sealing material of using therefore; But the existing Expanded Graphite Sealing Materials that directly adopts is often made packing ring, or utilizes packing form coiling moulding, like this because expanded graphite originally is in graphite-like when conventional state; Therefore, be easy to occur loose shape, so be unfavorable for carrying, collection; And expanded graphite also might form liquid under the situation of ultrahigh pressure, is extruded by high pressure, therefore necessary this is solved.
The model utility content
The utility model technical problem to be solved is the deficiency that still can not be applied to superhigh temperature, high pressure to existing expanded graphite packing ring, proposes a kind of expanded graphite seal washer that can use superhigh-temperature and-pressure.
The technological scheme that the utility model adopts is:
The superhigh-temperature and-pressure seal washer of a kind of metal and expanded graphite combination; Comprise two-layer above expanded graphite packing ring; Between every two-layer expanded graphite packing ring, accompany wire gaze, and be wrapped with the metal ring on one deck roll coil of strip limit in the one side of outermost expanded graphite packing ring.
Further embodiment is, the wire gaze that accompanies between described every two-layer expanded graphite packing ring is the latticed wire gaze by the Stainless Steel Wire braiding, and latticed wire gaze bonds together through Bond with expanded graphite pad up and down.
Further embodiment is; The metal ring on described roll coil of strip limit is that the soft metal makes; And be that forming a kind of bottom surface is metallic gasket from following outside and inner edge to upper overturning parcel graphite gasket, the upper strata is the metal of expanded graphite pad and the composite gland bush of expanded graphite pad combination.
The gasket ring of the utility model is used for the connection sealing between the equipment end interface of various HTHPs; The expanded graphite pad is after interface connects; To be in a kind of by in the formed metal enclosed ring of encirclement of the one side between the end interface and the metal ring on roll coil of strip limit; Lost efficacy in case the sealing of the expanded graphite on the connection device receives superhigh-temperature and-pressure, will still only can in the metal enclosed ring of encirclement, can not leak; The outside more effective of expanded graphite pad contacted with sealing part, satisfy the requirement of sealing.

Embodiment
Come further to set forth the utility model below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1; The superhigh-temperature and-pressure seal washer of a kind of metal and expanded graphite combination; Comprise two-layer above expanded graphite packing ring 2, between every two-layer expanded graphite packing ring, accompany wire gaze 3, and be wrapped with the metal ring 1 on one deck roll coil of strip limit in the one side of outermost expanded graphite packing ring.
Further embodiment is, the wire gaze 3 that accompanies between described every two-layer expanded graphite packing ring is the latticed wire gazes by the Stainless Steel Wire braiding, and latticed wire gaze bonds together through Bond with expanded graphite pad up and down.
Further embodiment is; The metal ring on described roll coil of strip limit is that the soft metal makes; And be that forming a kind of bottom surface is metallic gasket from following outside and inner edge to upper overturning parcel graphite gasket, the upper strata is the metal of expanded graphite pad and the composite gland bush of expanded graphite pad combination.
The gasket ring of the utility model is used for the connection sealing between the equipment end interface of various HTHPs; The expanded graphite pad is after interface connects; To be in a kind of by in the formed metal enclosed ring of encirclement of the one side between the end interface and the metal ring on roll coil of strip limit; Lost efficacy in case the sealing of the expanded graphite on the connection device receives superhigh-temperature and-pressure, will still only can in the metal enclosed ring of encirclement, can not leak; The outside more effective of expanded graphite pad contacted with sealing part, satisfy the requirement of sealing.
