Abstract

The utility model discloses a high accuracy intelligence water gauge. The inertial flow rate is increased by the adding of jet apparatus inside the cavity of the gauge; the valve and the cassette mechanism are integrated before being installed outside the gauge, which makes the assembly of the gauge simpler; the reliability of valve control is improved by reasonable employment of the spare batteries and the replaceable batteries and by photoelectric driven in-place detecting. The utility model provides an excellent management terminal for water saving and effective water source management.

Description

A kind of high-precision intelligent water meter

The utility model relates to a kind of rotor dry type high-precision digital intellectual water meter.

Along with the further raising of industrialization degree, environment and resource problem become increasingly conspicuous, and people are more and more higher to the interdependent degree of environment, using water wisely and the management easily and effectively of water resource also seemed more and more important.For adapting to this demand, various intellectual water meters are come upon the stage.But in use more or less all there are some problems in these water meters, and we conclude and sum up these problems in the process of research and development: 1, rotor water gauge initiating flow is bigger; 2, adopt disposable lithium cell to be packaged in case inside more, can't change in the operating period of whole water meter, this has all proposed very high requirement to battery and automatically controlled part, has increased production cost; 3, the accurate gauge tap valve of valve actuator.The existence of these problems reduces the reliability of water meter, and failure rate increases.

Fundamental purpose of the present utility model provides a kind of rotor water gauge, and this water meter is set up a fluidic device on the basis of original rotor water gauge, with the accurate measurement of realization low discharge, and reduces the initiating flow.

Another purpose of the present utility model provides a solution for the intellectual water meter continued power.

Another purpose of the present utility model provides a kind of rotor water gauge, has increased by a photoelectric detector in the reducer structure of this water meter drive control valve, comes gauge tap valve more accurately with this, reduces the power attenuation that causes because of stall.

A purpose more of the present utility model provides a kind of intellectual water meter, and movement and valve seat can be as unitary member, installation and debugging more easily.

The technical solution of the utility model: valve seat 2 is housed in the die cavity of watchcase 1, valve seat 2 water inlets are equipped with a pair of potsherd 3 and 4, potsherd 3 is fixed on the valve seat 2, potsherd 4 is connected with valve seat 2 by compression spring 5, and at the front end of potsherd 3, valve seat 2 water inlets have small through hole, jet pipe 6 is communicated with small through hole and movement 20 a certain water inlets, movement 20 fuses by clamping screw 7 with valve seat 2, and compacting ring 9 compresses movement 20 and valve component by pressing plate 8, and screws with watchcase 1.Speed reduction unit 9 is connected with valve 22 by output shaft 21.On the wherein gear of speed reduction unit optical detection device 18 is housed, on the one-level gear torsion spring 18-1 is housed therein, the two ends of torsion spring are separately fixed on this gear and the clamping plate.Photovalve 18 links to each other with master control borad 16 by line, the device 17 of winning the confidence is connected with master control borad 16 by line, base 15 is fixing by bolt and pressing plate 8, water meter loam cake 11 is connected with base 15 by rotating shaft 10, replaceable battery 13 is housed in the loam cake 11, Card Reader coil 14, battery 13 causes master control borad 16 with the extension line of card read head for ID 14 by rotating shaft 10.

Advantage of the present utility model: can change battery easily; Photoelectric detection switch valve situation guarantees that the switch valve operation is accurate; Movement and valve seat integral structure are convenient to install and reprocess; Reduce the initiating flow by fluidic device.

Structural representation is seen attached sheet.

The course of work of the present utility model: valve was a closed condition when water meter was just adorned, after user's water authority on sale is purchased water, to purchase water information by teletransmission information Control or non-contact IC card input water meter, after primary control program receives information, send instruction, motor reducer rotates, output shaft drives valve and opens valve events, torsion spring on the gear is screwed simultaneously, photovalve in the speed reduction unit detects opens valve angle, when detected angle was consistent with set angle, control system was interrupted the power supply to reducing motor, finishes out valve events.In the water utilizing process, when the water yield in downstream was very little, a pair of potsherd of water inlet was in fit-state under the effect of spring, and the water of water inlet enters by jet aperture and flexible pipe and promotes wheel rotation in the movement.Impeller drives the sheet metal that embeds wherein, and the device of winning the confidence of impeller loam cake is imported master control borad with signal and finished water consumption calculating and in good time the demonstration.

When the water yield that the user purchases used up, primary control program added reverse voltage to reducing motor, made the common valve-off of elastic force of motor reverse drive and torsion spring, and photovalve detects and closes valve angle simultaneously, finishes the pass valve events.
