The utility model proposes a kind of impellers, are used for flowmeter, wherein the flowmeter can be used as the important component of soft water valve
One of, which can be used for metered flow.
In an embodiment of the utility model, referring to figs. 1 to Fig. 4, which includes:
Support frame 10, the support frame 10 have in the water inlet end 110 and water outlet 120 being oppositely arranged；
Interconnecting piece 20 is located in the support frame 10, and the interconnecting piece 20 is equipped with from the water outlet 120 towards the water inlet
The axis hole 210 for holding 110 directions to extend；
Blade 30, one end connect the outer peripheral surface of the interconnecting piece 20, and the other end connects the inner peripheral surface of the support frame 10；
And
Diversion division 40, set on the interconnecting piece 20 towards one end of the water inlet end 110, and the diversion division 40 is back to institute
The side of interconnecting piece 20 is stated in tapered setting.
Specifically, usually there is water stream channel in flowmeter, and shaft and impeller 1 are provided in its water stream channel,
The shaft is consistent with the flow direction of water stream channel, and impeller 1 is rotatably mounted in shaft.When water flow is passed through from the water stream channel,
Water flow passes through impeller 1, and impeller 1 can be driven to rotate.
It can be measured by the rotation situation to impeller 1, and then the flow of water stream channel is calculated.Wherein it is possible to
Day by setting rotary encoder, photoelectric sensor, the detection devices such as Hall sensor, to the rotation amount of impeller 1 (angular displacement,
Rotating cycle etc.) it measures.
In order to reduce resistance of water flow when through impeller 1 by impeller 1, in the present embodiment, to the knot of above-mentioned impeller 1

It applies in example, diversion division 40 is additionally provided on impeller 1, which is located at interconnecting piece 20 towards one end of water inlet end 110, water conservancy diversion
Portion 40 back to the side of interconnecting piece 20 be in tapered setting, in this way, water flow first passes through diversion division when flow direction water inlet end 110
40 carry out drainage and water conservancy diversion, generate active force to blade 30 at 30 position of current deflecting blade, and then convenient for water flow, prevent water
The accuracy of measuring of flowmeter has been effectively ensured by generating disorder, the more conducively rotation of impeller 1 when impeller 1 in stream.
For the ease of the manufacturing of impeller 1, impeller 1 is preferably moulding, support frame 10, interconnecting piece in the present embodiment
20, blade 30 and diversion division 40 are preferably that integrated injection molding forms.
Further, in order to guarantee that diversion division 40 can play the effect of drainage and water conservancy diversion to water flow, in the present embodiment, this is led
Stream portion 40 at least partly protrudes from the water inlet end 110 of support frame 10, at this point, diversion division 40 protrudes from the water inlet end of support frame 10
110, before water flow does not enter support frame 10, water conservancy diversion and drainage can be carried out to water flow in advance, by 30 position of current deflecting blade
Place, so that more conducively water flow generates active force to blade 30.
There are many shapes of above-mentioned diversion division 40, such as the diversion division 40 is preferably hemispherical or taper is arranged, in favor of
Form guide face on the surface of diversion division 40, reduce diversion division 40 to the flow resistance of water flow, more conducively to the water conservancy diversion of water flow, draw
Stream.
