Abstract
The utility model relates to a kind of flange connecting sealing device, comprise flange, with the link of Flange joint, be provided with seal ring between flange and link, flange is provided with groove towards one end of seal ring; Flange, to having triangle boss, offers vee gutter in the corresponding position of link, is provided with " V " RunddichtringO in vee gutter, and described " V " RunddichtringO is close on the both sides end face of vee gutter.Flange and link are dismantled simply, good sealing effect, solve that conventional planar flange seal does not sternly easily leak, stud crosses locking and cause that the rotten tooth of silk mouth is locked, the problem that flange seal offset plate easily tears heavily is torn in maintenance open; By adopting triangle sealing configuration, triangle boss and vee gutter match to be incorporated in vee gutter and are provided with " V " RunddichtringO, because sealing surface is narrower, compression area is little, and because being subject to the stop of groove face, wash away by medium and the tendency of corroding few, good sealing effect.
Description
Technical field
The utility model relates to technical field of sealing technology, particularly relates to a kind of flange connecting sealing device.
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.
Flange makes pipe and the interconnective part of pipe, is connected to pipe end; Also the flange that the equipment that is used in is imported and exported is had, for the connection between two equipment, as speed reducer flange.Traditional flat flange connects or flanged joint, generally be interconnected releasable connection as one group of combined sealing structure by flange, pad and bolt three, as black box, there is following problem in pad: during connection, screw is crossed locking and easily caused the rotten tooth of silk mouth locked during use; Heavily flange is torn open in overhaul of the equipments or unloading process; Gasket seal easily tears; Long-time use pad is aging easily causes poorly sealed leaking.
Model utility content
The utility model, in order to overcome deficiency of the prior art, provides a kind of flange connecting sealing device, improves its sealability, prevents from revealing.
The utility model is achieved through the following technical solutions:
A kind of flange connecting sealing device, comprise flange, link with Flange joint, in flange and link, all offer concentric mounting hole, be provided with seal ring between described flange and link, described flange is provided with groove towards one end of seal ring; Described flange, to having triangle boss, offers vee gutter in the corresponding position of link, is provided with " V " RunddichtringO in described vee gutter, and described " V " RunddichtringO is close on the both sides end face of vee gutter.
As optimal technical scheme of the present utility model, described seal ring is stuck in groove towards the side of flange and coordinates with flange, and described seal ring is against on link towards the side of link.
As optimal technical scheme of the present utility model, connected between described flange and link by assembling set, described assembling set comprises earrings, pad, stud, and described earrings is fixedly connected with stud.
As optimal technical scheme of the present utility model, the cross section of described groove is trapezoidal, and described seal ring "O"-ring, the diameter of "O"-ring is identical with the groove depth of groove.
Compared with prior art, the beneficial effects of the utility model are: in the utility model, flange and link are dismantled simply, good sealing effect, solves that conventional planar flange seal does not sternly easily leak, stud crosses locking and cause that the rotten tooth of silk mouth is locked, the problem that flange seal offset plate easily tears heavily is torn in maintenance open; By adopting triangle sealing configuration, triangle boss and vee gutter match to be incorporated in vee gutter and are provided with " V " RunddichtringO, because sealing surface is narrower, compression area is little, and because being subject to the stop of groove face, wash away by medium and the tendency of corroding few, good sealing effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-flange; 2-link; 3-mounting hole; 4-seal ring; 5-groove; 6-triangle boss; 7-" V " RunddichtringO; 8-earrings; 9-pad; 10-stud.
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.
Described a kind of flange connecting sealing device, the link 2 comprise flange 1, being connected with flange 1, in flange 1 and link 2, all offer concentric mounting hole 3, be provided with seal ring 4 between described flange 1 and link 2, described flange 1 is provided with groove 5 towards one end of seal ring 4; Described flange 1, to having triangle boss 6, offers vee gutter in the corresponding position of link 2, is provided with " V " RunddichtringO 7 in described vee gutter, and described " V " RunddichtringO 7 is close on the both sides end face of vee gutter.Flange 1 and link 2 are dismantled simply, good sealing effect, solve that conventional planar flange seal sternly does not easily leak, stud cross lock cause the rotten tooth of silk mouth locked, overhaul the problem of heavily tearing flange seal offset plate open and easily tearing; By adopting triangle sealing configuration, triangle boss and vee gutter match to be incorporated in vee gutter and are provided with " V " RunddichtringO, because sealing surface is narrower, compression area is little, and because being subject to the stop of groove face, wash away by medium and the tendency of corroding few, good sealing effect.
