Description
Technical field
The utility model relates to a kind of detachable and combination type large-diameter water meter;Belong to the fields of measurement of flow.
Background technology
Horizontal Dismantlable helical blade type water meter, its structure is as shown in figure 1, its shortcoming is, in order to which the rotation of horizontal direction is turned
The rotation of vertical direction is changed to, drives the metering of gear counter.It must be realized by one group of turbine and worm.Due to spiral type
Impeller is acted on by turbine and worm eccentric moment, greatly increases the resistance of spiral type impeller, reduces the sensitivity of water meter.Simultaneously
The abrasion of spiral type impeller two end axles thimble is exacerbated, reduces the service life of water meter.The shortcomings that most fatal, is, when pipeline pressure
Power due to water pump start and stop, valve opening and closing and when producing water hammering, horizontal screw wing impeller is impacted by hydraulic pressure to be accelerated suddenly, and turbine
Worm screw can not but make an immediate response.Blade broken, or turbine and worm gear is caused to break, water meter is directly scrapped.In addition, heavy caliber
The bore of mechanical water meter, its mechanical drive principle is limited, the restriction of manufacturing technology and cost typically can only be within 300 millimeters.
In summary, mechanical water meter is the realization of measuring principle, and the gear counter that must have, and constrains the sensitive of water meter
Degree, measuring accuracy, service life, the bore of pipeline and the teletransmission of data.
The content of the invention
The utility model proposes a kind of detachable and combination type large-diameter water meter, its purpose is to overcome existing skill
Drawbacks described above present in art.
Technical solution of the present utility model:Detachable and combination type large-diameter water meter, it is characterized in that by connecting pipe
Straight length, the communication concentrator on straight length, and dismountable multiple small-bore mechanical pick-up devices in straight length
Formula electronic water meter movement group is formed.
The advantages of the utility model:
1)Detachable and combination type large-diameter water meter, due to tying down without mechanical gear, can break away from transmission principle,
The restriction of manufacturing technology and cost;Using the principle of computer distributed system, on same pipeline section, with multiple standardization
The small-bore mechanical pick-up device formula electronic water meter movement parallel combination of production, may make up any heavy caliber remote transmitting water meter;
2)Detachable and combination type large-diameter water meter only has spiral type impeller, without turbine and worm and gear counter, resistance
Power is small, high sensitivity;
3)For spiral type impeller two end axles thimble without eccentric moment, abrasion is also small, improves the service life of water meter.Spiral shell
Wing formula impeller can be freely with water movement, and water meter is scrapped in the strike for not being afraid of water hammering again;
4)One huge impeller is substituted by the small impeller of multiple same specifications, easy to manufacture, and parts can also batch
Production, it is not necessary to huge production equipment and metering calibration equipment, and then the technology and cost of manufacture are substantially reduced, and water meter
Bore it is unrestricted again.

Bore water meter movement forms;As shown in Figure 2.
As shown in Figure 3,4, the current of described pipeline are by each small-bore mechanical pick-up device formula electronic water on pipeline section
The guiding of table movement front end guiding gutter, respectively flow through the spiral type leaf of each small-bore mechanical pick-up device formula electronic water meter movement
Wheel, spiral type wheel rotation is promoted, a small bar magnet is embedded with the axle of each spiral type impeller rear end;
Described small bar magnet rotates with spiral type impeller, produces the rotating excitation field of a small range, magnetic field upset, touches
The magnetic-tunnel-effect sensor in the water meter circuit box of spiral type impeller axle side is sent out, produces pulse signal, wakes up CPU work, meter
The cumulative water of number simultaneously stores.
The communication concentrator of mechanical pick-up device formula electronic water meter is installed outside described pipeline, communicates the calculating in concentrator
Machine, connect by 485 buses and the microcontroller bus of each small-bore mechanical pick-up device formula electronic water meter circuit box on pipeline section
Mouth connection;The metering single-chip data on each small-bore mechanical pick-up device formula electronic water meter movement is gathered, accumulation calculating goes out whole
The flow of individual water meter diametrically, storage, display and the whole large-diameter water meter data of teletransmission.
The large-scale impeller is substituted by the small impeller of multiple same specifications.Easy to manufacture, parts can also be produced in batches.
Huge production equipment and metering calibration equipment are not needed, and then substantially reduces the technology and cost of manufacture.And the mouth of water meter
Footpath is unrestricted again, as shown in Figure 3.
