Description
Technical field
Metering field is the utility model is related to, more particularly to a kind of low discharge measures more accurate water meter structure.
Background technology
Water meter is a kind of common water-carrying capacity metering outfit, when water enters impeller box from water meter water inlet, just impacts leaf
Wheel, impeller is set to produce driving moment, when the driving moment of impeller is more than the resistance of impeller, impeller just starts to rotate, and water meter starts
Metering.Impeller can cause thimble to produce stiction with impeller between centers, this part stiction is just due to the Action of Gravity Field of itself
Resistance when being rotated as impeller, in the case of low discharge, water meter can not accurately measure water-carrying capacity.
Utility model content
The purpose of this utility model is to overcome disadvantage mentioned above, there is provided a kind of low discharge measures more accurate water meter structure,
The water meter is by being arranged at the airtight cavity of impeller internal, and suffered buoyancy is equal to its own when making impeller submerged in water
Gravity, so as to be suspended in water so that metering is more accurate during low discharge.
What the utility model was realized in：A kind of low discharge measure more accurate water meter structure, including water meter body with
And it is rotationally connected with the impeller in water meter body, it is characterised in that：The impeller includes impeller body, lower end is fixedly arranged on impeller sheet
The impeller axle of body upper end, the wolfram steel axle for being fixedly arranged on impeller axle upper end and the axle sleeve for being arranged at impeller body lower end, the impeller
Body and impeller axle are rotationally connected with water meter body by wolfram steel axle and axle sleeve, the impeller body and impeller axle and water meter sheet
Body leaves gap on axially engaging and it is moved up and down with respect to water meter body in the axial direction in the outer masterpiece used time, institute
Stating impeller also includes being arranged in impeller body and impeller axle body and has the cavity of under shed, and the axle sleeve is fixedly arranged on cavity
Cavity is caused to form closed cavity in opening, the closed cavity suspends when enabling impeller submerged in water in water.
In order to which preferably wolfram steel axle is fixed with impeller body, the impeller body uses single injection-molded, institute
State wolfram steel axle and be located in advance in the injection mold of impeller body and positioned.
In order to preferably be sealed to cavity, company is fixed using ultrasonic bonding in the opening of the axle sleeve and cavity
Connect.
For prior art, the utility model has advantages below：
(1) low discharge provided by the utility model measures more accurate water meter structure, by being arranged at the close of impeller internal
Closed chamber body, suffered buoyancy is equal to the gravity of its own when making impeller submerged in water, so as to be suspended in water so that rill
Metering is more accurate during amount；
(2) low discharge provided by the utility model measures more accurate water meter structure, and simple in construction, manufacturing cost is low, makes
With dependable performance, there are wide market prospects.
Brief description of the drawings
The utility model is described in further detail in conjunction with the embodiments with reference to the accompanying drawings：
Fig. 1 is the structural representation that the utility model low discharge measures more accurate water meter structure；
Fig. 2 is the structural representation of impeller in Fig. 1.
Symbol description in figure：1st, water meter body, 2, impeller, 21, impeller body, 22, impeller axle, 23, wolfram steel axle, 24, axle

Embodiment
The utility model content is described in detail with reference to Figure of description and specific embodiment：
As Figure 1-Figure 2, more accurate water meter structure is measured for a kind of low discharge provided by the utility model, including
Water meter body 1 and the impeller 2 being rotationally connected with water meter body 1, it is characterised in that：The impeller 2 include impeller body 21,
Lower end is fixedly arranged on the impeller axle 22 of the upper end of impeller body 21, the wolfram steel axle 23 for being fixedly arranged on the upper end of impeller axle 22 and is arranged at impeller
The axle sleeve 24 of the lower end of body 21, the impeller body 21 and impeller axle 22 are rotationally connected with water meter by wolfram steel axle 23 and axle sleeve 24
In body 1, the impeller body 21 and impeller axle 22 leave gap with water meter body 1 on axially engaging and cause it in outer masterpiece
Used time can move up and down with respect to water meter body 1 in the axial direction, and the impeller 2 also includes being arranged at impeller body 21 and impeller
In the body of axle 22 and the cavity 25 with shed, the axle sleeve 24 be fixedly arranged in the opening of cavity 25 so that cavity 25 formed it is closed
Cavity, the closed cavity suspends when enabling impeller 2 submerged in water in water.The design of the size of cavity 25 need to cause
The buoyancy suffered when submerged in water of impeller 2 is equal to the gravity of its own.Can be first according to FIt is floating=GLiquid is arranged=ρLiquidgVRowCalculate leaf
Take turns 2 it is submerged in water when suffered buoyancy, then determine the size of cavity 25 further according to the weight of impeller 2.
In order to which preferably wolfram steel axle is fixed with impeller body, the impeller body 21 uses single injection-molded,
The wolfram steel axle 23 is located in the injection mold of impeller body 21 in advance to be positioned.
In order to preferably be sealed to cavity, the opening of the axle sleeve 24 and cavity 25 is consolidated using ultrasonic bonding
Fixed connection.
