Abstract
The utility model relates to a kind of sealing configuration, comprise upper flange end cap and lower flange end cap, described upper flange end cap and lower flange end cap are provided with concentric threaded mounting hole, the lower end surface of described upper flange end cap is provided with the tenon platform of outwardly convex, upper-end surface and the tenon platform corresponding position of lower flange end cap offer groove, and tenon platform is installed in a groove; Also be provided with sealing gasket between described upper flange end cap and lower flange end cap, one end contact of described sealing gasket on the end face of tenon platform, and ends on the ladder-type end face of lower flange end cap.The utility model, by adopting tenon-slot type sealing configuration, because sealing surface is narrower, compresses area little, and because being subject to the stop of groove surface, wash away by medium and the tendency of corroding few, be also easy to centering during installation, sealing gasket uniform force, sealability is reliable.
Description
Technical field
The utility model relates to technical field of sealing technology, particularly relates to a kind of sealing configuration covered for flange end, for improving the sealability of two flange end caps.
Background technique
Sealing be anti-fluid or solid particle from reveal between adjacent junction plane and prevent introduced contaminants as
Dust and moisture etc. invade component or the measure of machinery equipment inside.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.
Summary of the invention
The utility model, in order to overcome deficiency of the prior art, provides a kind of sealing configuration, improves its sealability, prevents from revealing.
The utility model is achieved through the following technical solutions:
A kind of sealing configuration, comprise upper flange end cap and lower flange end cap, described upper flange end cap and lower flange end cap are provided with concentric threaded mounting hole, the lower end surface of described upper flange end cap is provided with the tenon platform of outwardly convex, upper-end surface and the tenon platform corresponding position of lower flange end cap offer groove, and tenon platform is installed in a groove; Also sealing gasket is installed between described upper flange end cap and lower flange end cap.
As optimal technical scheme of the present utility model, one end contact of described sealing gasket on the end face of tenon platform, and ends on the ladder-type end face of lower flange end cap.
As optimal technical scheme of the present utility model, described sealing gasket is made up of polyurethane material.
As optimal technical scheme of the present utility model, in described threaded mounting hole, bolt is installed, the end face of bolt and lower flange end cap is lined with elastic sealing gasket, and uses fastening nuts.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by adopting tenon-slot type sealing configuration, because sealing surface is narrower, compression area is little, and because being subject to the stop of groove surface, wash away by medium and the tendency of corroding few, be also easy to centering during installation, sealing gasket uniform force, sealability is reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-upper flange end cap; 2-lower flange end cap; 3-tenon platform; 4-groove; 5-sealing gasket; 6-threaded mounting hole; 7-bolt; 8-elastic sealing gasket; 9-nut.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of sealing configuration, comprise upper flange end cap 1 and lower flange end cap 2, described upper flange end cap 1 and lower flange end cap 2 are provided with concentric threaded mounting hole 6, in described threaded mounting hole 6, bolt 7 is installed, bolt 7 with the end face of lower flange end cap 2 are lined with elastic sealing gasket 8, and fastening with nut 9, upper flange end cap 1 and lower flange end cap 2 are installed together.
The lower end surface of described upper flange end cap 1 is provided with the tenon platform 3 of outwardly convex, upper-end surface and tenon platform 3 corresponding position of lower flange end cap 2 offer groove 4, and tenon platform 3 is arranged in groove 4; Between described upper flange end cap 1 and lower flange end cap 2, sealing gasket 5 is also installed.One end contact of described sealing gasket 5 on the end face of tenon platform 3, and ends on the ladder-type end face of lower flange end cap 2, and described sealing gasket 5 is made up of polyurethane material.Gap between two flange end cap mating faces can be sealed, isolation or cut-out leakage, increase the resistance in leakage, can produce higher gasket stress simultaneously.
By adopting tenon-slot type sealing configuration, because sealing surface is narrower, compress area little, and because being subject to the stop of groove surface, wash away by medium and the tendency of corroding few, be also easy to centering during installation, sealing gasket uniform force, sealability is reliable.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
