Abstract
The utility model discloses an injective tightly sealed flange, which relates to a flange device used for connecting pipelines as well as pipelines and equipment. The injective tightly sealed flange is composed of a bolt hole, a sealed groove, and a material injecting hole. The bolt hole, the sealed groove, and the material injecting hole are arranged on the injective tightly sealed flange and are respectively welded on two pipelines which are connected. Two flanges are twisted by bolts and nuts, then seal packing is pumped in the sealed groove via the material injecting hole by a high-pressure water jet, and an annular high pressure sealing strip is formed. Thus, the reliability of flange seal is ensured. The injective tightly sealed flange solves the leakage problem of flanges fundamentally. The utility model has the advantages of compact and reasonable structure, convenient installation, labor saving, and material saving. Thus, the injective tightly sealed flange is suitable for being installed between the pipelines, between the pipelines and the equipment, and between the equipment.
Description
The utility model relate between a kind of pipeline and the pipeline or pipeline and equipment between be connected employed flange apparatus.
Usually need in the engineering two pipelines or pipeline and equipment are coupled together, mostly finish this connection procedure with flange.The joint that is about to each pipeline is loaded onto a flange respectively, two flanges is tightened with bolt again.Shi Buhui is definitely flat because two flanged surfaces join, when pipeline internal medium by the time, can flow out at the surface of contact place of two flanges.
For preventing the leakage between flange, all be between two flanges, to put seal ring to carry out leak stopping envelope close at present.Be out of shape owing to seal ring is very easily aging, again because there is certain perpendicularity in flanged surface with pipeline, or the like reason, after pipeline pressure test and operation, tend to occur leakage.To do for this reason and do over again and a large amount of work such as maintenance, bring inconvenience to engineering.
The purpose of this utility model provides a kind of compact structure, processing is manufactured conveniently and the flange apparatus of good sealing effect.
To achieve these goals, the utility model has seal groove and stuffing box packing injection orifice on flange.Flange is that two flanges are screwed on bolt when playing interconnect function, after tightening, stuffing box packing is mapped in the seal groove by injection orifice, thereby is connecting annular high pressure sealing band of middle part formation with High Pressure Gun, played the seal action of joint between flange, guaranteed not leak.
Below in conjunction with specific embodiment concrete feature of the present utility model is elaborated.
Fig. 1 is a structural representation of the present utility model.
See accompanying drawing 1, on flange 1, have bolt hole 2, seal groove 3 and material hole 4.
The schematic representation of Fig. 2 when to be that this reality is novel connect two sections pipeline sections.
See accompanying drawing 2, two flanges are welded together with left side pipe 9 and right pipe 10 respectively.
With bolt 5 and nut 6 two flanges are screwed on.Inject stuffing box packing 8, material hole is sealed up with screw 7.
With reference to the accompanying drawings 1,2 pairs of working principles of the present utility model of accompanying drawing are further elaborated.
It mainly is by bolt hole that the utility model can be annotated formula high sealing flange, and seal groove and closed hole are formed.When the joint of pipe laying, the flange 1 (seeing accompanying drawing 1) that has seal groove 3 and material hole 4 is welded on respectively on promptly left pipe 9 of connecting tube and the right pipe 10 (seeing accompanying drawing 2).With bolt 5 and nut 6 two flanges are coupled together then.By material hole 4 stuffing box packing 8 is squeezed in the seal groove 3, form an annular high pressure sealing band connecting the middle part, material hole is sealed up with screw 7.Guaranteed not leaking of flange.
The utility model has fundamentally solved the leakage problem between flange, has guaranteed the reliability of sealing.It need not use seal washer and adopt an annular sealing strip to seal, thereby has solved the problem of leaking the replacing packing ring that must stop production owing to the aging distortion of packing ring.Can not be with the pressure additional fillers in case leakage must not stop production after several years, guarantee normally carrying out of production.The simple and reasonable installation of the utility model is manufactured conveniently, and saving of labor, material-saving.Therefore be applicable between various pipelines and the pipeline, being connected between pipeline and the equipment.
Claims (1)
1. formula high sealing flange apparatus be can annotate for one kind, bolt hole, seal groove and material hole it is characterized in that on flange, having.The flange that has bolt hole, seal groove and material hole is welded on two pipeline connecting parts respectively, the perhaps joint between equipment and the equipment, with bolt, nut two flanges are tightened, by material hole seal groove is injected in stuffing box packing, form an annular high pressure sealing band, with screw that the material hole envelope is tight.
