Description
Technical field
The utility model relates to the technical field of paint spraying, is a kind of connection sealing configuration of Teflon application tank body specifically.
Background technique
Teflon coating take teflon as the fluoro coatings of matrix resin, and English name is Teflon, is usually referred to as again Furtulon, the rich dragon of iron, Teflon, polytetrafluoroethylene etc. (being all the transliteration of Teflon).Teflon coating is a kind of unique high-performance coating, combine insulation stability and the low frictional properties of heat resistance, chemical inertness and excellence, have the comprehensive advantage that other coating cannot contend with, the flexibility of its application makes it can for the product of nearly all shape and size.
Teflon is divided into PTFE, FEP, PFA, ETFE several fundamental type: PTFE (teflon) non-viscous paint can use continuously at 260 DEG C, there is maximum operation (service) temperature 290-300 DEG C, extremely low friction factor, good wear resistance and fabulous chemical stability.FEP (fluorinated ethylene propylene copolymer) non-viscous paint melt-flow when toasting forms nonporous film, and have remarkable chemical stability, fabulous not sticky characteristic, maximum operation (service) temperature is 200 DEG C.PFA (cross fluoroalkyl compound) non-viscous paint the same with FEP when toasting melt-flow form nonporous film.The advantage of PFA has higher continuous serviceability temperature 260 DEG C, the strong and unyielding degree that tool is stronger, is particularly suitable for using antiseized and chemical resistance under the high temperature conditions to use field.ETFE is the copolymer of a kind of ethene and tetrafluoroethylene, and this resin is the most tough and tensile fluoropolymer, can form the coating that a layer height is durable, has remarkable chemical resistance, and can continuous operation at 150 DEG C.
After Teflon application, there is following characteristic: 1, not viscosity: nearly all material does not bond with Teflon film.Very thin film also demonstrates well not adhesion property.2, heat resistance: Teflon film has excellent heat-resisting and low temperature tolerance characteristics.Short time can be high temperature resistant to 300 DEG C, generally can use continuously between 240 DEG C ~ 260 DEG C, have significant thermostability, and it can work and not brittle under cryogenic temperature, does not at high temperature melt.3, sliding: Teflon film has lower friction factor.When load is slided, friction factor changes, but numerical value is only between 0.05-0.15.4, moisture resistance: Teflon film without water stained on its surface and oil, is also not easily stained with solution during production operation, and as being stained with a small amount of dirt, simple wiping can be removed.Dead time is short, saves man-hour and can increase work efficiency.5, wearability: under high load, has excellent wear-resisting property.Under certain load, possesses wear-resistant and inadhesive two-fold advantage.6, corrosion resistance: Teflon corrodes by medicine hardly, can protect part to avoid suffering the chemical corrosion of any kind.Teflon is widely used in high temperature resistant, to require to do viscosity industry.
The application of Teflon coating is divided into the dispersion coating coating process of wet type and the powder paint coating method of dry type usually.The coating process of dispersion coating cladding material is evenly distributed in solvent form dispersion liquid (solid matter is mixed in a liquid), and this mixture is atomized by high-pressure air and is sprayed at workpiece surface.The cladding material used in powder paint coating method is ultrafine solid particle forms, avoid using solvent, thus the Divergent Phenomenon occurred when avoiding coating to adhere to, make micro mist shape coating granule be attached on workpiece, subsequently, the micro mist of coating melting in baker.
The reactor or the storage tank that are coated with Teflon coating are generally two kinds of structures: one is all-in-one-piece tank body, and whole tank body is made of one piece, application teflon coatings in inner tank wall; Another kind of structure then adopts split type tank body, tank body generally comprises upper cover and can body, and above-mentioned upper cover and can body are the parts of two splits, namely distinguishes application Teflon coating on each comfortable inwall, then upper cover and can body are interfixed, and be combined into a tank body.
Relative to the tank body of integral type, split type tank body processing is convenient, and painting work efficiency is higher, and also more simple to the inspection process of coating, and production cost is also relatively low.
But there is following defect in technological scheme used in the prior art:
The scheme upper cover of split type tank body and can body fixed in prior art normally arranges flange at upper cover and position corresponding to can body; by flange, two are interfixed; simultaneously in order to ensure the sealability of joint, usually also will sealing gasket be set between the flanges.Corresponding to the Teflon coating that inner tank wall adopts, sealing pad is generally fluororesin sealing gasket.The flange adopted in prior art generally is face-flange, and the chemical product adopting the tank body of Teflon application to be often directed to corrosivity or toxicity uses, thus higher to the seal request of tank body, to avoid leaking of stock in tank body, the sealing of face-flange is relatively poor, cannot meet sealing demand.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of connection sealing configuration of Teflon application tank body.
The technological scheme that the utility model is taked for the technical problem existed in solution known technology is:
The connection sealing configuration of Teflon application tank body of the present utility model, above-mentioned Teflon application tank body comprises upper cover and can body, upper cover and can body coaxial, and be fixedly connected with by flange between upper cover with can body, in upper cover flange and can body flange either side flanged surface on annular recess is set, annular recess and tank body coaxial, opposite side flanged surface is arranged the annular projection with above-mentioned matching grooves, between upper cover flange and can body flange, arrange fluororesin sealing gasket, the matching form of the pad figure shape of fluororesin sealing gasket and above-mentioned groove and projection closes.
The utility model can also adopt following technical measures:
Above-mentioned annular recess inner face is arc surface, and namely the section of groove is circular arc, is also arc surface with the convex surfaces of fit depressions; Fluororesin sealing gasket is arc surface corresponding to above-mentioned groove with protruding position relative set.
The thickness of described fluororesin sealing gasket each position is identical.
