Abstract
The utility model discloses a turbine flow guiding device and a turbine flowmeter. The turbine flow guiding device comprises a center shaft and a plurality of flow guiding parts annularly arranged on a side wall of the center shaft. One ends of the plurality of flow guiding parts are located at one end of the center shaft to form a liquid inlet, and the other ends of the plurality of flow guiding parts extend to the other end of the center shaft along the axial direction of the center shaft to for a liquid outlet. The ends of the plurality of flow guiding parts located at the position of the liquid inlet are bent towards the anti-clockwise direction to be in an R angle, and the R angle is within a range of 25 degrees to 75 degrees. According to the turbine flow guiding device and the turbine flowmeter, the ends of the plurality of flow guiding parts located at the position of the liquid inlet are bent towards the anti-clockwise direction to be in the R angle, so that when R angle flow guiding is adopted, repeatability changes remarkably and tends to be stable, energy consumption of the turbine flow guiding device is the lowest, and accuracy and repeatability of the whole flowmeter are changed fundamentally.
Description
Technical field
The utility model relates to a kind of turbo flow meter, relates in particular to a kind of turbine guiding device of turbo flow meter and the turbo flow meter with this turbine guiding device of this turbo flow meter.
Background technology
The turbo flow meter of existing turbo flow meter is through type, as shown in Figure 1, this turbo flow meter comprises the turbine guiding device, this turbine guiding device comprises central shaft 1 and the some diversion divisions 2 of layout on the sidewall of this central shaft 1 ringwise, one end of these some diversion divisions 2 all is positioned at an end of this central shaft 1 and forms inlet, and the other end of these some diversion divisions 2 all extends to the other end of this central shaft 1 and forms liquid outlet along the axial direction of this central shaft 1.This turbine guiding device forms turbulent flow when rotating, flowmeter frequency of occurrences when detecting is constantly changed, thereby make the repeated relatively poor of flowmeter, and the liquid steady flow is not good.
The utility model content
In view of this, the turbo flow meter that is necessary to provide the better turbine guiding device of a kind of liquid steady flow and has this turbine guiding device.
The utility model is to realize like this, a kind of turbine guiding device, it comprises central shaft and the some diversion divisions of layout on the sidewall of this central shaft ringwise, one end of these some diversion divisions all is positioned at an end of this central shaft and forms inlet, the other end of these some diversion divisions all extends to the other end of this central shaft and forms liquid outlet along the axial direction of this central shaft, the end of these some diversion divisions that is positioned at the inlet place is all counterclockwise crooked and be the R angle, and the angle at this R angle is in 25 degree in 75 degree scopes.
the utility model also provides a kind of turbo flow meter, two turbine guiding devices that it comprises and is arranged on the relative both sides of this impeller, this turbine guiding device comprises central shaft and the some diversion divisions of layout on the sidewall of this central shaft ringwise, one end of these some diversion divisions all is positioned at an end of this central shaft and forms inlet, the other end of these some diversion divisions all extends to the other end of this central shaft and forms liquid outlet along the axial direction of this central shaft, wherein, the end of these some diversion divisions that is positioned at the inlet place is all counterclockwise crooked and be the R angle, the angle at this R angle is in 25 degree in 75 degree scopes.
The turbine guiding device that the utility model provides and have the turbo flow meter of this turbine guiding device, the end of these some diversion divisions that is positioned at the inlet place is all counterclockwise crooked and be the R angle, therefore, when adopting R angle water conservancy diversion, the repeatability significant change, trend is stable, and the energy consumption of turbine guiding device is also minimum, makes like this accuracy of whole flowmeter and the change that essence occurs repeatability.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also Fig. 2 and Fig. 3, the structural representation of the turbine guiding device of the turbo flow meter that it provides for the utility model better embodiment.This turbine guiding device is arranged in turbo flow meter, two turbine guiding devices that this turbo flow meter comprises impeller and is arranged on the relative both sides of this impeller.This turbine guiding device comprises central shaft 10 and the some diversion divisions 20 of layout on the sidewall of this central shaft 10 ringwise.
One end of these some diversion divisions 20 all is positioned at an end of this central shaft 10 and forms inlet, the other end of these some diversion divisions 20 all extends along the axial direction of this central shaft 10, and all counterclockwise crooked and be R angle 30 when extending to the other end of this central shaft 10.When adopting R angle 30 water conservancy diversion, repeated significant change, trend is stable, and the energy consumption of turbine guiding device is also minimum, makes like this accuracy of whole flowmeter and the change that essence occurs repeatability.
The angle at this R angle can be in 25 degree in 75 degree scopes, and its design effect reaches optimum condition like this.
In other embodiments, also can lengthen at the inlet place of traditional turbo flow meter, and form endways R angles in 25 degree-75 degree scopes.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
