Abstract
Disclosed is a steel pipe sealing flange assembly belonging to the technical field of pipe connection equipment, which is characterized by comprising two flanges (1) and a cushion block (4). The two flanges (1) are in chirally symmetrical distribution. The opposite surfaces of the two flanges (1) are provided with positioning grooves (3) corresponding to the block (4). The depths of the positioning grooves (3) are one half the thickness of the cushion block (4). The middle part of the cushion block (4) is provided with a through hole and the inner diameter of the through hole is identical to the inner diameter of an opening at the middle part of each flange (1). According to the utility model, the flanges are uniform in both shape and specification. The two ends of a pipe are free from being differentiated from each other as front and rear ends after the welding process, so that the free butt-joint is realized. Meanwhile, the steel pipe sealing flange assembly is quick in positioning effect and good in sealing effect.
Description
Technical field
Steel pipe sealing flange assembly, belongs to pipeline connection device technical field.
Background technique
Flange is a kind of conventional pipeline connection device.Traditional flange designs two kinds of corresponding flanges often in the docking problem that solves flange, a kind of structure that is designed with protrusion, and a kind of structure that is designed with depression, so that two kinds of flanges are convenient to location docking.But these flanges are being welded to after pipeline, must relatively can connect by the corresponding flanged joint of pipeline; When many times working environment is comparatively narrow, as the pipeline in drive, once the flanged joint that has which bar pipeline is not inconsistent with connecting direction, the narrow space in mine laneway cannot be reversed pipeline, and after need to expending very large manpower and materials pipeline being transported back to well face and reversed above, row is transported back again.This just has a strong impact on manufacturing efficiency, increases cost of production.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of pipeline to connect tightly, locate convenient, the unified steel pipe sealing flange assembly of shape.
The utility model solves the technological scheme that its technical problem adopts: this steel pipe sealing flange assembly, it is characterized in that: comprise symmetrically arranged two flange plate and a cushion block, on the opposing side of two described flange plate, have the locating slot adapting with cushion block shape, the degree of depth of locating slot is 1/2 of pad thickness, and the middle part of described cushion block has the through hole with the intermediate openings same inner diameter of flange plate.
Flange plate of the present utility model is as basic system, shape specification is unified, after pipeline two ends welding without differentiation, pipeline two ends are identical, between pipeline, realize and freely docking, and in use cushion block wanted to put into the locating slot of a flange plate, in the time of docking, utilize again cushion block location, the half cushion block protruding is positioned in the locating slot of another flange plate, under the positioning action of cushion block, can both locate fast, in tunnel, uses and need not worry pipeline transporting direction.Between cushion block and flange plate, adding after rubber cushion sealing, sealing effect is tight.
Described cushion block be shaped as circle or regular polygon.The cushion block shape specification of circle or regular polygon is unified, when use without differentiation, easily packing in the time that locating slot is installed, without adjustment.
The thickness of described cushion block and the Thickness Ratio of flange plate are 0.5 ~ 1:1.The thickness of cushion block is excessive affects self intensity of flange plate.The thickness of cushion block is too small to be arranged on and to protrude after locating slot obviously not, affects locating effect.
Compared with prior art, the beneficial effect that steel pipe sealing flange assembly of the present utility model has is: flange plate of the present utility model is as basic system, shape specification is unified, after pipeline two ends welding without differentiation, pipeline two ends are identical, between pipeline, realize and freely docking, in use cushion block is wanted to put into the locating slot of a flange plate, in the time of docking, utilize again cushion block location, the half cushion block protruding is positioned in the locating slot of another flange plate, under the positioning action of cushion block, can both locate fast, in tunnel, use and need not worry pipeline transporting direction.Between cushion block and flange plate, adding after rubber cushion sealing, sealing effect is tight.The cushion block shape specification of this new design is unified, when use without differentiation, easily packing in the time that locating slot is installed, without adjustment.The pad thickness of this new design just in time meets self intensity of flange plate and the locating effect of cushion block.
Brief description of the drawings
Fig. 1 is the schematic diagram of the preferred embodiment of a kind of steel pipe sealing flange assembly of the present utility model.
Fig. 2 is the schematic diagram of a kind of steel pipe sealing flange assembly in the time of pipeline coupled condition.
Fig. 3 is a kind of schematic diagram of cushion block 4 of steel pipe sealing flange assembly.
Wherein, 1, flange plate 2, bolt fixed hole 3, locating slot 4, cushion block 5, bolt 6, rubber cushion.
Embodiment
Fig. 1 ~ 3rd, most preferred embodiment of the present utility model, is described further below in conjunction with 1 ~ 3 pair of the utility model of accompanying drawing.
With reference to accompanying drawing 1,2: a kind of most preferred embodiment of the utility model steel pipe sealing flange assembly, comprise symmetrically arranged two flange plate 1 and a cushion block 4, on the opposing side of two flange plate 1, have the locating slot 3 adapting with cushion block 4 shapes, being welded on pipeline without location groove face of two flange plate 1, the degree of depth of locating slot 3 is 1/2 of cushion block 4 thickness, in the time that docking, flange plate 1 adds rubber cushion 6 in locating slot 3, after docking, cushion block 4 leaves the thickness surplus of two rubber cushions 6 after installing, and while utilizing bolt 5 to clamp sealing through bolt fixed hole 2, can ensure sealability.The middle part of cushion block 4 has the through hole with the intermediate openings same inner diameter of flange plate 1, simultaneously also identical with the internal diameter of connecting tube, can not increase flow resistance; The thickness of cushion block 4 is identical with the thickness of flange plate 1, meets self intensity of flange plate 1 and the locating effect of cushion block 4.With reference to accompanying drawing 3: cushion block 4 be shaped as circle, be convenient to the interior placement of locating slot 3, without adjustment.
Other mode of executions: shown in same Fig. 1 of basic structure, 2, difference is: cushion block 4 be shaped as regular polygon.In the time that cushion block 4 drops or places separately, be not easy to roll to lose and retain equally the easily advantage to locating slot 3 interior placements.The Thickness Ratio of the thickness of cushion block 4 and flange plate 1 is self intensity of guarantee flange plate 1 that 0.5:1 can be larger, has also taken into account the locating effect of cushion block 4 simultaneously.
Concrete using method: being welded on and needing the pipe end that connects without location groove face this sealing flange, first at the interior placement rubber cushion 6 of locating slot 3, again cushion block 4 is placed in the locating slot 3 of a flange, utilize cushion block 4 to dock with locating slot 3 location of another flange, the set screw nut that screws bolt 5 completes the connection of pipeline.
The above, it is only preferred embodiment of the present utility model, be not the restriction of the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
