Specific embodiment
It is described in detail below with reference to embodiment referring to attached drawing, to be carried out more to technical characteristic of the invention and advantage
Deep annotation.
As shown in figs 1-9, a kind of intelligent flow meter of the invention, including pedestal 7,7 both ends of pedestal are respectively communicated with water inlet pipe 8
With outlet pipe 4,7 middle cavity of pedestal accommodates impeller 10, and 10 number of teeth of impeller is odd number, the single blade root of impeller 10
Fluting, the rotary shaft bottom slot of impeller 10, the rotary shaft top of impeller 10 are embedded in magnetite 3, the cavity of 7 top of pedestal
Accommodate Hall sensor 12,12 electrical connection circuit plate 2 of Hall sensor, circuit board 2 is installed in the cavity of top cover 1, top cover 1 with
Pedestal 7 connects.
Further, the blade of the impeller 10 is rectangle, and the root of blade opens up dovetail groove, the impeller 10
The trapezoidal groove shape of root of blade is right-angled trapezium, and two waist edge angles of right-angled trapezium are 45 degree, the leaf of the impeller 10
The piece number is 7, and the rotary shaft bottom slot number of impeller 10 is 3, and the blade of the impeller 10 is by seven equal part of circumference, impeller
The fluting of 10 rotary shaft bottom is by circumference trisection.
Further, it is equipped with end cap 11 between the top cover 1 and pedestal 7, sealing is installed between end cap 11 and pedestal 7
Circle 9, described 4 one end of outlet pipe is fixed with bracket 5, and the temp probe 6 installed in bracket 5 is inserted into the cavity of outlet pipe 4, institute
12 installation site of Hall sensor stated is concordant with magnetite 3, the axis coaxle of the water inlet pipe 8 and outlet pipe 4, the base
The cylinder to match with 10 rotary shaft of impeller is equipped in seat 7.
The working principle of apparatus of the present invention are as follows: external water stream enters 7 cavity of pedestal that impeller 10 is housed by water inlet pipe 8,
The blade and impeller 10 of current scour impeller 10 rotate, with a cylindrical magnetite 3, this magnetic in the rotary shaft of impeller 10
Stone 3 rotates together with impeller 10, and for each revolution, the N of magnetite 3, the pole S can move to the sensitive surface with Hall sensor 12
Alignment issues telecommunications pulse, of different sizes, the rotation speed of impeller 10 of water flow so that Hall sensor 12 be allowed to generate reaction
Degree is also different, and the time interval for generating pulse so as to cause Hall sensor 12 is different, and external control system can be with this
The length in burst length judges the size of water flow, to keep out water temperature to adjust the heating power of heater to reach
That spends is relative constant.
Apparatus of the present invention improve structure, are the design of impeller 10 first, and impeller 10 selects odd-numbered blade, 7 leaves
10 design of wheel is not symmetry status because of odd-numbered blade, blade is in dynamic unbalance state, has when such impeller 10 rotates
Conducive to the rotation of blade；The notch there are three 1X1mm is opened at cylinder rotary shaft cooperation on impeller 10 and pedestal 7, this notch can
Stuck phenomenon is generated to effectively prevent bits present in water flow to enter between impeller 10 and rotary shaft；10 blade of impeller is close
The width of blade of rotary shaft root will narrow, that is, open up dovetail groove, this to design the resistance that can reduce water flow.The present apparatus will go out
6 design of coolant-temperature gage probe is at outlet pipe 4, and design is to guarantee the external hot water heated by heater by front water in this way
The water temperature flowed at outlet pipe 4 after being sufficiently mixed of road is relatively uniform, ensures that temperature measurement is accurate in this way.
The innovation of apparatus of the present invention has 4 points: one, impellers 10 to be designed as 7 blades, this design allows impeller 10 to rotate
When be in unbalance dynamic state always；The slot of three 1x1mm is opened at the rotary shaft of two, impellers 10, as shown, 3 slots are uniform
It is prevented stuck in shaft circumference convenient for deslagging respectively；The three leaf terminal end widths of 7 are 4mm, and root is narrowed to 3.2mm,
Position leniently is excessive using 45 ° of oblique angles to narrow position, it is therefore an objective to when impeller 10 rotates, reduce resistance to water-flow；Four, go out water temperature
Degree probe 6 is arranged at outlet pipe 4, it is ensured that the accuracy of temperature detection.
In apparatus of the present invention, magnetite 3, temp probe 6, Hall sensor 12, circuit board 2 and outside control system and
