Abstract
The utility model relates to a kind of impeller assemblies of water meter, including water meter case and it is placed in the intracorporal metrological service of the shell of water flowmeter, the metrological service is made of gearcase, impeller box, impeller, axis and adjustable plate, the impeller includes the shaft and blade group of integral structure, the blade group prolongs shaft outer profile circumferential arrangement, and the shaft upper/lower terminal is equipped with dome.This structure begins entire impeller in crossing water, either big flow or small flow, remains the stability of rotation, promote measuring accuracy, also improve the service life of water meter using the integrated design of rotating steel shaft stainless in impeller and shell.The utility model is designed reasonably is suitble to large-scale promotion.
Description
Technical field
The utility model relates to the component of water meter more particularly to a kind of impeller assemblies of water meter.
Background technique
Impeller rotation in crossing water is the fixation stainless steel shaft drive by housing bottom 4a in water meter, as described in Figure 2, existing
Impeller shaft structure in technology includes rotation axis and multiple blade 1a, and the rotation axis uses upper and lower two-stage structure, difference
For magnet end 2a and with the conflict end 3a of top contact, as moment cross water it is big if, cause impeller rotation it is extremely unstable, to water meter
Measuring accuracy and service life have a great impact.
Utility model content
In view of the above-mentioned state of the art, that the technical problem to be solved by the utility model is to provide precision is high, makes
With the impeller assembly of the water meter of service life length.
Utility model solves technical solution used by above-mentioned technical problem are as follows: a kind of impeller assembly of water meter, including water
Watch shell and it is placed in the intracorporal metrological service of the shell of water flowmeter, the metrological service is by gearcase, impeller box, impeller, axis and tune
It saves plate to constitute, the impeller includes the shaft and blade group of integral structure, and the blade group prolongs shaft outer profile circumferential arrangement, institute
It states shaft upper/lower terminal and is equipped with dome.
Further, the blade group is plastic in the shaft outer wall.
Compared with prior art, the utility model has the beneficial effects that this structure is using stainless in impeller and shell
The integrated design of rotating steel shaft begins entire impeller in crossing water, either big flow or small flow, remains rotation
Stability promotes measuring accuracy, also improves the service life of water meter.The utility model is designed reasonably is suitble to large-scale promotion.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the impeller assembly of water meter of the utility model；
Fig. 2 is the structural schematic diagram of prior art water meter turbine component.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, for the preferred embodiment in the utility model embodiment,
Instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creation
Property labour under the premise of every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, a kind of impeller assembly of water meter, including water meter case and it is placed in the intracorporal meter of the shell of water flowmeter
Measuring mechanism, the metrological service are made of gearcase, impeller box 3, impeller, axis and adjustable plate, and the impeller includes integral structure
Shaft 2 and blade group 1, the blade group 1 prolongs 2 outer profile circumferential arrangement of shaft, and 2 upper/lower terminal of shaft is equipped with circle
Top.
Preferably, the blade group 1 is plastic in 2 outer wall of shaft.
Compared with prior art, the utility model has the beneficial effects that this structure is using stainless in impeller and shell
The integrated design of rotating steel shaft begins entire impeller in crossing water, either big flow or small flow, remains rotation
Stability promotes measuring accuracy, also improves the service life of water meter.The utility model is designed reasonably is suitble to large-scale promotion.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in
All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting
Related claim.
