Description
Technical field
The utility model relates to a kind of cement industry seal arrangement, more particularly, particularly relates to a kind of flange connecting sealing device.
Background technique
Sealing is anti-fluid or solid particle from revealing between adjacent junction plane and preventing introduced contaminants as the component of the intrusion such as dust and moisture machinery equipment inside or measure.The leakage of equipment is very important quality problems, leakage of oil, leak, the normal operation of the equipment that has a strong impact on that leaks gas, outward appearance, working efficiency and working life, and can environmental pollution be caused, waste energy.Cause the reason of leakage to mainly contain two aspects: one is the result due to machining, the surface of engineering goods certainly exists various defect and shape and size deviation, therefore, inevitably produces gap in mechanical parts connection place; Two is that sealing both sides exist pressure difference, and working medium will be revealed by gap.Sealing can be divided into the large class of the motive sealing two between the static seal between geo-stationary junction plane and relative movement junction plane.Static seal mainly contains dot encapsulation, and glue sealing seals three major types with contacting.According to working pressure, static seal is by being divided into mesolow static seal and high pressure static seal.It is softer that material commonly used by mesolow static seal, the pad sealing that pad is wider, and high pressure static seal is then comparatively hard with material, the metallic shim that contact width is very narrow.Motive sealing can be divided into rotary seal and reciprocation sealing two kinds of fundamental types.Whether contact with the component of its effect relative movement by Sealing, contact seal and noncontact seal can be divided into.In general, the good airproof performance of contact seal, but limit by fretting wear, be applicable to the occasion that sealing surface linear velocity is lower.The sealing of noncontact seal is poor, is applicable to the occasion of fair speed.Sealing between current flange end cap mostly is plane sealing, and pad covers the sealing surface of whole flange, and the area of contact of pad and flange is comparatively large, and the impacting force provided is less, is easy to be extruded seal face, causes leakage.
Model utility content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of flange connecting sealing device of rational in infrastructure, favorable sealing property.
The technical solution of the utility model is achieved in that a kind of flange connecting sealing device, comprise the upper flange end cap and lower flange end cap that cooperatively interact, upper, wherein two sides that lower flange end cap is relative are respectively equipped with the semicircular indentations cooperatively interacted, relative semicircular indentations coordinates fixed outer rotating shaft, on each semicircular indentations inwall, be wherein radially provided with the locating slot of fixing O shape circle, the semicircular indentations inwall that the locating slot lowest positions being positioned at lower flange end cap is corresponding is provided with oil-return groove vertically, oil-return groove oil outlet end and upper, the Seal cage that lower flange end cap is formed communicates, the end face that upper and lower flange end cap contacts circumferentially is respectively equipped with at least one corresponding auxiliary flute, in each corresponding auxiliary flute, is provided with auxiliary seal adhesive tape.
In above-mentioned a kind of flange connecting sealing device, the upper and lower flange end cap end face of described auxiliary flute side is provided with the semicircle positioning convex strip and half round locating grooves that cooperatively interact.
In above-mentioned a kind of flange connecting sealing device, described oil-return groove upward, the Seal cage that formed of lower flange end cap tilts, and is 1-3 ° with the angle α of horizontal plane bottom oil-return groove.
After the utility model adopts said structure, first coordinated with sealing joint strip by auxiliary flute, because sealing surface is narrower, compress area little and be subject to the restriction of auxiliary flute, realize the effective sealing between upper and lower flange end cap, sealing joint strip is only subject to rational extrusion-deformation, not only favorable sealing property, and working life significant prolongation; Secondly, by the setting of oil-return groove, make the lubricant oil in rotating shaft to get back in seal arrangement rapidly, can not leakage be caused.Further, by arranging the semicircle positioning convex strip and half round locating grooves that cooperatively interact, upper and lower flange end cap is made to be easy to location, easier for installation.
