Description
Technical field
The utility model relates to originally drainage facility field, in particular to a kind of water meter calibration.
Background technique
The accuracy for needing to measure before water meter factory is examined and determine, and water meter calibration is not only convenient for administrative department of measurement pair
Manufacture, repair measurement instrument quality exercise supervision inspection, guarantee factory water meter accuracy, safeguard user personal benefit
Benefit can also comply with the strong table tool of utility network, intelligentized development trend offer flexibility height, extended capability effectively
Meet the management requirement of Running-water Company and industry, but current water meter calibration is in the prevalence of shadow influenced by ambient temperature
The problem of big, structure is complicated, poor accuracy is rung, be also improved space.For this purpose, applicant invented a kind of water in 2016
Table calibrating installation has substantially solved the above problem, but in the system, due to each application No. is 2016205037079
Checklist will carry out differing larger between the different flow of monitoring of different flow three times, therefore in conversion, such as every from 4 sides
Hour is transferred to 0.03 side per hour, it may appear that instability of flow, it is difficult to which the case where adjusting influences verification result.
Summary of the invention
Stable water meter calibration system is converted in order to make up for the defects of the prior art, the utility model provides a kind of flow
System.
The utility model is achieved by the following technical solution:
A kind of water meter calibration, including PLC control system, vacuum tank, meter-clamping apparatus and flow adjustment pipe, flow are adjusted
Pipeline includes three pipelines, characterized in that every pipeline is designed with fast joint of waterpipe, sets in the fast joint of waterpipe
Abacus, the orifice plate are provided with metering orifice, and the diameter of three metering orifices is different, pneumatic operated valve is equipped on three pipelines, steady
It presses and connects flow initial adjustment pipeline between tank and meter-clamping apparatus, the flow initial adjustment pipeline is made of three initial adjustment pipelines in parallel, and three
The internal diameter of initial adjustment pipeline and the diameter of metering orifice correspond, and are equipped with flowmeter on each initial adjustment pipeline and initial adjustment is pneumatic
Valve.
The diameter of three metering orifices and three kinds of different inner diameters of three initial adjustment pipelines are respectively DN25, DN10 and DN2.5.
The beneficial effects of the utility model are:
The utility model first passes through flow initial adjustment pipeline and reduces flow when carrying out flow conversion, carries out initial adjustment, in this way
The flow for flowing through flow adjustment pipe can be closer to the measurement flow needed, then definitely define flow by flow control, at this moment
It is not in pervious situation fluctuated, it is easy to which the measurement flow just needed accurately counts to calculate
According to improving the accuracy of verification result.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings:
Fig. 1 is the schematic view of the front view of the utility model；
Fig. 2 is the overlooking structure diagram of flow adjustment pipe；
Fig. 3 is the overlooking structure diagram of flow initial adjustment pipeline；
Fig. 4 is the schematic cross-sectional view of the connection structure of fast joint of waterpipe.
In figure, 1 water tank, 2 water pumps, 3 vacuum tanks, 4 meter-clamping apparatus, 5 detection platforms, 6 flow adjustment pipes, 61 orifice plates, 62 gas
Dynamic valve, 63 pipelines, 64 metering orifices, 65 fast joint of waterpipe, 66 washers, 7 commutators, 8 weighing containers, 9 flow initial adjustment pipelines, 91

Specific embodiment
Attached drawing is specific embodiment of the utility model.As shown in Figures 1 to 4, this kind of water meter calibration, including PLC
Control system and water tank 1, water pump 2, vacuum tank 3, meter-clamping apparatus 4, detection platform 5, flow adjustment pipe 6, commutator 7, weighing are held
Device 8, flow adjustment pipe 6 include three pipelines 63, and each pipeline 63 all consists of two parts, and pass through one between this two parts
A fast joint of waterpipe 65 connects, and an orifice plate 61 is placed in the washer 66 of 65 one end of fast joint of waterpipe, is provided on orifice plate 61
The diameter of one metering orifice 64, the metering orifice 64 on three pipelines 63 is respectively DN25, DN10 and DN2.5, each pipeline 63
On a pneumatic operated valve 62 is all installed, between vacuum tank 3 and meter-clamping apparatus 4 connect a flow initial adjustment pipeline 9, flow initial adjustment pipeline
9 are made of three initial adjustment pipelines 92 in parallel, the specification of three initial adjustment pipelines 92 also be respectively DN25, DN10 and DN2.5, it is each
Flowmeter 91 and initial adjustment pneumatic operated valve 93 are equipped on initial adjustment pipeline 92.DN25, DN10 and DN2.5 indicate their internal diameter or straight
Diameter is respectively 25,10,2.5 millimeters.Of course for sealing, upper gasket 66 can also be all installed in the two sides of orifice plate 61.
After checklist connects, first by flow adjustment pipe 6 and flow initial adjustment pipeline 9 two pipelines 63 and two initial adjustments
Pipeline 92 is closed, and internal diameter and the identical pipeline 63 of diameter and initial adjustment pipeline 92 are retained, after the flow value measurement of this specification,
It simultaneously closes off again, then opens the pipeline 63 and initial adjustment pipeline 92 of another same size, then detected.
In addition to the technical characteristic described in the specification, remaining technical characteristic is technology known to those skilled in the art.
