Abstract
The invention relates to an integral insulation flange pipe, which consists of an upper catheter, a lower catheter, a sleeve barrel, insulation gaskets, a sealing pad and an insulation sleeve. The sealing pad is arranged after the first sealing by adopting the lip type technology, a dual sealing effect is realized, the sealing ring can be rubber, a seam between the sleeve barrel and the lower catheter is tightly filled by the insulation sleeve, the insulation sleeve can be made of plastics or other metal insulation materials, the two end surfaces of the upper catheter and the lower catheter are provided with insulation gaskets, the insulation gaskets are polycarbonate enhanced plastics which can work for a long time in a temperature range being -60 to +120 DEG C and is added with a proper amount of glass fiber, the sleeve barrel and the upper catheter are welded into a whole, and the sleeve barrel can be in a spherical shape, a rectangular shape and any other space three-dimensional geometrical shape. The mechanical performance is high, the integral assembly is simple, the use is convenient and fast, the installation is convenient, and in addition, an electric chemical corrosion prevention effect is realized.
Description
Technical field:
The present invention relates to a kind of flanged fitting, particularly a kind of integrated type insulated flange pipe fitting has the anti-corrosion insulation performance.
Background technique:
Insulating joint is an indispensable important component in gas transmission and distribution and the oil wire system.Its effect is that pipeline and equipment are separated each other, makes equipment avoid electrochemical corrosion, thereby prolongs its operating life.But adopt insulating sleeve with the level between the screw bolt and nut of present most joint and the flange with its mutual insulating.The axial tension load that this structure can bear receives the restriction of plastic sheath step intensity, can not be very high; The axial compressive force that can bear is insulated the limit of elasticity restriction of pad, and excessive axial compressive force can make it follow the string and destroy sealability; If a side of insulation spacer has the tendency that reduces sealing under the effect of flexural load, opposite side then has because of the stressed excessive possibility that follows the string.Outside its sealing insulator is directly exposed to, directly contact with wet gas or soil, its necessary insulating property reduce.Because the influence that changed by landform, landforms and other natural causes, the stressing conditions of insulated flange are very complicated, thereby cause two flanged surfaces to tilt, misplace, sealing is impaired, and often leaks.
Summary of the invention:
To the technical deficiency of existing the said goods, the object of the invention provides a kind of integrated type insulated flange pipe fitting, is made up of upper and lower conduit, sleeve, insulation spacer, sealing gasket and insulating bush.
The technical solution adopted for the present invention to solve the technical problems is: adopt " lip formula " technology that sealing gasket is located at first after the sealing, play the double seal effect, seal ring can be rubber; Insulating bush enriches space between sleeve and the downcomer, and insulating bush can be plastics or other fertile metallic insulators are processed; Upper and lower conduit both ends of the surface are provided with insulation spacer, and described insulation spacer is that temperature is the polycarbonate (PC) reinforced plastic of an amount of glass fibre of adding of ability long-term work in-60～+ 120 ℃ of scopes; Sleeve and upper conduit are welded into one, and the shape of sleeve can be sphere, rectangle and other any space multistory geometrical shapies;
Beneficial effect of the present invention: mechanical property is high, the integral body assembling is simple, easy to use, easy for installation and have anti-couple-corrosion.
Accompanying drawing is described:

Among the figure 1, upper conduit 2, downcomer 3, sleeve 4, insulation spacer 5, sealing gasket

Embodiment:
As shown in Figure 1, the invention provides a kind of integrated type insulated flange pipe fitting, form by upper conduit 1, downcomer 2, sleeve 3, insulation spacer 4, sealing gasket 5 and insulating bush 6.In the drawings, upper conduit 1 compresses insulation spacer 5, sealing gasket 6 with downcomer 2 both ends of the surface.Two catheter ends derive from sleeve 3 and are suppressed the plastic deformation force that produces when closing up in the face of the clamping force of insulating sealer.The effect of insulating bush 6 in structure be not only with sleeve 3 and downcomer 2 isolate, insulation, and the supporting force when sleeve 3 closed up passes to downcomer, thus it is stressed to make rigidity see, the plastic item stressing conditions improves.Force upper conduit 1 to move down in the sleeve 3 closing in processes, thereby make upper conduit 1 and downcomer 2 both ends of the surface that insulation spacer 4 and sealing gasket 5 are compressed, guarantee insulation, sealability between upper conduit 1 and downcomer 2 interfaces.After the closing in, sleeve 3 is welded into one with upper conduit 2, makes it that advantages of high bearing capacity arranged.
In shown in the last figure, the main effect of insulation spacer 4 is the distances that keep upper conduit 1 and downcomer 2 both ends of the surface; Sealing gasket 5 guarantees sealing necessary between the two.Insulation spacer 4, insulating bush 6 are to be employed in the polycarbonate (PC) reinforced plastic that temperature is an amount of glass fibre of adding of ability long-term work in-60～+ 120 ℃ of scopes, and its compressive strength is up to 16480N/cm2.This structure can be born bigger stretching or compressive load, can bear the flexural load of certain numerical value again, and bearing capacity is stronger. and its insulating part is wrapped in airtight space by envelope, does not receive the influence of wet gas, so insulation, sealability is reliable and stable.
