Description
Technical field
The present invention relates to a kind of adjustable whole pump replacement and connect pipe nipple, belong to the Fluid Machine and Fluid Dynamics Engineering field.
Background technique
Industries such as desulfurization at home, the multiple fertilizer of phosphorus, aluminium, pump is indispensable system's constituent element.The major function of pump is that medium is transported in another place or the equipment from a place, workload before it has reduced greatly and the danger that has reduced original transportation.The medium that pump is carried has clear liquid, slurries, and some is the slurries that contain a large amount of particles, even solid particle or dust.Just at present, no matter be domestic abroad, though the flow passage part material of pump has bigger research or big breakthrough on wear-resisting, decay resistance, but the replacing frequency of utilization of pump is also very high.The product that each pump manufacturer production is come out all has the characteristics of oneself, and as importing and exporting the flange bore, pump intake is to the off-centre of outlet, and difference such as the center of pump is high.If more renew pump, the connection mouth and the internal diameter between the connecting tube of pump generally can there are differences, and therefore when changing pump, also will replace the pipe nipple that is connected that links to each other with original pipeline.Existing technology is exactly to manufacture one to connect pipe nipple, and a kind of method is the flanged (FLGD) Taper Pipe pipe nipple in connection mouth internal diameter cast inblock two ends according to original internal diameter of the pipeline and pump, and is as shown in Figure 1; Another kind method is that two flanges are welded on the Taper Pipe according to the connection mouth internal diameter casting of original internal diameter of the pipeline and pump, and is as shown in Figure 2.But because the restriction of the condition at the error of mapping and scene, the flange bolt hole site of the connection pipe nipple of conventional construction is fixed, and when docking with the flange bolt hole of original pipeline, occurs certain deviation easily, causes bolt not adorned; Perhaps the eccentricity values of pipeline is different, causes the connection pipe nipple of whole pump replacement can't the pump of newly replacing closely be linked to each other with original pipeline at all; In addition, flange and intermediate conduit be welded as the welding of the conical surface and plane, welding effect is relatively poor, the weld joint easy-to-leak liquid.
Summary of the invention
When the connection pipe nipple that the objective of the invention is to solve the conventional construction replacement pump housing is connected with original pipeline, occurs adorn not Shang, adorning problems such as not firm, weld seam easy-to-leak liquid easily, and provide a kind of whole pump to replace the connection pipe nipple,
The objective of the invention is to realize through following technological scheme:
A kind of adjustable whole pump replacement of the present invention connects pipe nipple, comprises locking annulus, adjusting flange, big footpath pipe, Taper Pipe, path pipe and fastening flange; Big footpath pipe and path pipe are complementary with pump housing connection mouth and original internal diameter of the pipeline to be connected respectively, and the two ends end face of Taper Pipe is complementary with the end face of big footpath pipe and path pipe respectively; Big footpath pipe, Taper Pipe, path pipe are welded to form intermediate conduit successively; The external diameter of the internal diameter of fastening flange and path pipe is complementary, and fastening flange is enclosed within path pipe one end and is weldingly fixed on the end of path pipe; The internal diameter of locking annulus is complementary with the external diameter of big footpath pipe; Regulate the external diameter of the internal diameter of flange greater than big footpath pipe; And ring is processed with and locks the screens groove that the annulus external diameter is complementary in the adjusting flange; Regulate flange be enclosed within big footpath pipe one end and be fixed by welding in the locking annulus of pipe end, big footpath outwards spacing, make regulate flange can whole relatively connection pipe nipple rotation.
Wherein, regulate the external diameter of the minimum diameter of flange, make the adjusting flange spacing between locking annulus and fastening flange less than fastening flange.
Through in the screens groove of regulating flange and locking annulus, placing pad, the axial stroke to locking annulus end of flange is regulated in adjustment.
Fastening flange is connected also can adopt with the intermediate conduit end and is threaded with the locking annulus.
Fastening flange outer end end face after fixing is higher than path pipe end face, guarantees that end face cooperates closely between the flange of fastening flange and connecting tube.
Fastening flange is interchangeable in the fixed position of intermediate conduit end with the locking annulus, regulates the screens groove of flange and the interior shape of the locking annulus after the exchange and is complementary.
During use; Fastening flange one end is at first fastening with the flange screw of pipeline to be connected, then through the rotation adjusting flange, the screw of regulating flange is aimed at the flange screw of this end pipeline to be connected; And through in the screens groove of regulating flange and locking annulus, placing pad; The axial stroke to locking annulus end of flange is regulated in adjustment, make the flange shaft of regulating flange and this end end pipeline to be connected to join and screw fastening, link to each other with the tight of two end flange thereby realize connecting pipe nipple.
Beneficial effect
It is simple in structure, easy to operate, with low cost that the present invention connects pipe nipple; The convenient installation; Two ends of the present invention are through regulating being used of flange and fastening flange, have solved that screw misaligns between the adpting flange of traditional connection pipe nipple, the difficult point of span centre not, make its connection fastening; And face of weld is the disc welding, the problem of weld seam easy-to-leak liquid when having solved the welding of the conical surface and disc; And through regulating flange and axial cooperation of locking between the annulus placement pad realization adpting flange; The present invention can be widely used in being connected of the pump housing and connecting tube.
