Model utility content
For overcoming above the deficiencies in the prior art, the technical problems to be solved in the utility model is to provide one and can be effectively connected with the pump housing and pipeline, and greatly improves the new pump flange arrangement of installation efficiency and effect.
The technical solution of the utility model is: a kind of new pump flange arrangement, include the flange body for connecting the pump housing, axis hole is provided with at the center of flange body, be provided with multiple equally distributed bolt hole being positioned on the flange body around axis hole, outward extending annulus is also provided with in the side of the flange body being positioned at axis hole place, the axis of annulus and the dead in line of flange body, and the outer side wall of annulus successively decreases successively apart from one end away from flange body from one end of the close flange body of annulus to annulus of the distance of annulus axis, the shaft hole sleeve of flange body is connected on the pump housing, and on the madial wall of the axis hole contacted with the pump housing, be also provided with annular groove, also snap ring is embedded with in annular groove, also sleeve pipe is embedded with in bolt hole, also resilient pad is provided with between the madial wall and the outer side wall of sleeve pipe of bolt hole, and on the madial wall of sleeve pipe, be also provided with internal thread.
Above-mentioned new pump flange arrangement, wherein the number of bolt hole is 4, and resilient pad is rubber sheet gasket.
Above-mentioned new pump flange arrangement, is wherein also coated with lumarith at the outer surface of flange body, and the material of lumarith is stellite.
Above-mentioned new pump flange arrangement, wherein the madial wall of annulus also successively decreases successively apart from one end away from flange body from one end of the close flange body of annulus to annulus of the distance of annulus axis.
Above-mentioned new pump flange arrangement, the distance between the outer side wall of the annulus wherein near flange body one end and madial wall is greater than away from the distance between the outer side wall of the annulus of flange body one end and madial wall.
The beneficial effects of the utility model are: by adopting said structure, the utility model can be connected with the pump housing and pipeline effectively, and greatly improves installation efficiency and effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of new pump flange arrangement; Fig. 2 is the sectional structure schematic diagram along the A-A line in Fig. 1.
In figure: the pump housing 1, flange body 2, axis hole 3, bolt hole 4, annulus 5, annular groove 6, snap ring 7.
Embodiment
As depicted in figs. 1 and 2, a kind of new pump flange arrangement, include the flange body 2 for connecting the pump housing 1, axis hole 3 is provided with at the center of flange body 2, the flange body 2 be positioned at around axis hole 3 is provided with multiple equally distributed bolt hole 4, outward extending annulus 5 is also provided with in the side of the flange body 2 being positioned at axis hole 3 place, the axis of annulus 5 and the dead in line of flange body 2, and the outer side wall of annulus 5 successively decreases successively apart from one end away from flange body 2 from one end of the close flange body 2 of annulus 5 to annulus 5 of the distance of annulus 5 axis, the axis hole 3 of flange body 2 is socketed on the pump housing 1, and on the madial wall of the axis hole 3 contacted with the pump housing 1, be also provided with annular groove 6, snap ring 7 is also embedded with in annular groove 6, sleeve pipe (not shown) is also embedded with in bolt hole 4, resilient pad (also not shown in FIG.) is also provided with between the madial wall and the outer side wall of sleeve pipe of bolt hole 4, and on the madial wall of sleeve pipe, be also provided with internal thread.
By adopting said structure, flange body 2 is tightly connected with the pump housing 1 reliably by annular groove 6 and snap ring 7, thus prevent or avoid leak of liquid, by arranging annulus 5, just pipeline to be connected can be socketed in the annulus 5(of flange body 2 then more easily, can weld between pipeline with annulus 5 again), and because the external diameter of annulus 5 successively decreases from the inner successively to outer end, so the pipeline achieving different size all can be socketed on above-mentioned annulus 5, thus greatly facilitates the installation of pipeline.
As preferably, for above-mentioned new pump flange arrangement, wherein the number of bolt hole 4 is 4, resilient pad is rubber sheet gasket, in addition, for above-mentioned new pump flange arrangement, wherein also be coated with lumarith at the outer surface of flange body 2, and the material of lumarith is stellite.
As further preferred, for above-mentioned new pump flange arrangement, wherein the madial wall of annulus 5 also successively decreases successively apart from one end away from flange body 2 from one end of the close flange body 2 of annulus 5 to annulus 5 of the distance of annulus 5 axis, and further, distance between the outer side wall of the annulus 5 wherein near flange body 2 one end and madial wall is greater than away from the distance between the outer side wall of the annulus 5 of flange body 2 one end and madial wall, like this, can ensure or enhance the structural strength of the joint of flange body 2 and annulus 5 further.
In sum, by adopting said structure, the utility model can be connected with the pump housing and pipeline effectively, and greatly improves installation efficiency and effect.
By reference to the accompanying drawings the preferred embodiment of the utility model and embodiment are explained in detail above, but the utility model is not limited to the above-described embodiment and examples, in the ken that those skilled in the art possess, various change can also be made without departing from the concept of the premise utility.
