Technique scheme is the problem in order to eliminate the installation inconvenience that pump flange and pipeline flange bolt hole misplace and bring.
Model utility content
The purpose of this utility model can not be suitable for different regions Flange Standard thus the problem of the installation inconvenience caused to solve pump in prior art, and provide a kind of structure simple, can realize standardization, highly versatile, assembly manipulation is pump loose flange linkage structure easily.
The utility model realizes the technological scheme that its technical purpose adopts: a kind of pump loose flange linkage structure, comprise water inlet-outlet segment and flange body, described flange body is coaxially set and has coordinated axis hole and mounting hole, described cooperation axis hole and water inlet-outlet segment diametric fit are arranged, the aperture of described mounting hole is greater than the aperture coordinating axis hole, described water inlet-outlet segment corresponds to mounting hole and be provided with groove, described inside grooves is provided with reverse shaft block ring.This pump loose flange linkage structure, without the need to flange body being fixed on pipe by modes such as welding, but by reverse shaft block ring, flange body and water inlet-outlet segment are directly connected and fixed, the needs that the pipe that this loose flange linkage structure is enough applicable to various material connects, and structure is simple, highly versatile, do not need Special Equipment and professional and technical personnel when realizing pipe connection, site operation is time saving and energy saving, convenient and reliable.
As preferably, described reverse shaft block ring is oblate ring structure.Reverse shaft block ring adopts oblate ring design structure, and processing is simple, and enclasping force is larger, and compatible degree is higher, connects more firm, impermeable better effects if.
As preferably, the inner circle of described reverse shaft block ring is eccentric structure, the inner peripheral surface of described reverse shaft block ring is provided with two step surfaces, two described step surfaces with the diameter at reverse shaft block ring opening place for symmetry axis is symmetricly set on opening both sides.Inner circle adopts eccentric structure, its installation and removal of being more convenient for, and arrange two step surfaces and make to connect more firm, enclasping force is larger, and has impermeable function.
As preferably, the angle between described step surface and horizontal line is 2 to 10 to spend.Step surface and horizontal line angle are 2 to 10 to spend, and are convenient to installation and removal.
As preferably, cross section and the reverse shaft block ring of groove are equipped with as rectangular configuration.Reverse shaft block ring adopts oblate ring design, and water inlet-outlet segment channel section corresponding is with it set to rectangular configuration, and such structure compatible degree is high, and enclasping force is large, is connected firmly, impermeable effective.
The beneficial effects of the utility model are: the needs that this pump connects with the pipe that loose flange linkage structure is enough applicable to various material, and structure is simple, highly versatile, does not need Special Equipment and professional and technical personnel when realizing pipe connection, site operation is time saving and energy saving, convenient and reliable.Can join various flange, applied widely, efficiently quick for installation, processing is simple, and cost is low.

Embodiment
Also by reference to the accompanying drawings the technical solution of the utility model is described in further detail below by specific embodiment.
Embodiment 1:
In the embodiment shown in fig. 1, a kind of pump loose flange linkage structure, comprise water inlet-outlet segment 1 and flange body 2, flange body 2 is coaxially set and has coordinated axis hole 3 and mounting hole 4, axis hole 3 and water inlet-outlet segment 1 diametric fit is coordinated to arrange, the aperture of mounting hole 4 is greater than the aperture coordinating axis hole 3, and water inlet-outlet segment 1 corresponds to mounting hole 4 and be provided with groove 5, groove 5 inside is provided with reverse shaft block ring 6.The cross section of groove 5 and reverse shaft block ring 6 are equipped with as rectangular configuration (see figure 2).Reverse shaft block ring 6 is oblate ring structure.The inner circle of reverse shaft block ring 6 is eccentric structure, the inner peripheral surface of reverse shaft block ring 6 is provided with two step surfaces, 7, two step surfaces 7 with the diameter at reverse shaft block ring opening 8 place for symmetry axis is symmetricly set on opening 8 both sides (see figure 3).Angle between step surface 7 and horizontal line is 2 to 10 to spend.Angle in the present embodiment between step surface 7 and horizontal line selects 6 degree.
This pump loose flange linkage structure, by a reverse shaft block ring 6, realizes flange body and is connected with the quick of water inlet-outlet segment, highly versatile, can coordinate various flange, applied widely, and processing is simple, and cost is low, and installation efficiency is high.
And oppositely shaft block ring 6 adopts oblate ring structure to design, the cross section of the groove 5 on water inlet-outlet segment 1 corresponding is with it rectangular configuration, this spline structure, and processing is simple, and enclasping force is larger, and compatible degree is higher, connects more firm, impermeable better effects if.Meanwhile, reverse shaft block ring inner circle adopts eccentric design, and reverse shaft block ring inner peripheral surface is provided with two step surfaces 7, and step surface 7 and horizontal line angle are 2 to 10 spend, and being more convenient for, it mounts and dismounts.
This pump loose flange linkage structure, solve existing pump and can not be suitable for different regions Flange Standard thus the problem of the installation inconvenience caused, structure is simple, highly versatile, mating holes position can being facilitated, meanwhile, not needing Special Equipment and professional and technical personnel when realizing pipe connection, site operation is time saving and energy saving, convenient and reliable.
