Abstract
The utility model relates to originally drainage facility fields, particularly disclose a kind of apparatus for calibrating water meter.It includes PLC control system, vacuum tank, meter-clamping apparatus and flow adjustment pipe, flow adjustment pipe includes three pipelines, the internal diameter of three pipelines is different, motor-driven valve and pneumatic operated valve are equipped on three pipelines, flow initial adjustment pipeline is connected between vacuum tank and meter-clamping apparatus, the flow initial adjustment pipeline is made of the different initial adjustment pipeline of three internal diameters in parallel, is equipped with flowmeter and initial adjustment pneumatic operated valve on each initial adjustment pipeline.The utility model is when carrying out flow conversion, flow initial adjustment pipeline is first passed through to reduce flow, carry out initial adjustment, the flow for flowing through flow adjustment pipe in this way can be closer to the measurement flow needed, pervious situation fluctuated would not occur when adjusting the measurement flow of needs again, the measurement flow for being easy for being adjusted to need improves the accuracy of calibrating to calculate accurately data.
Description
Technical field
The utility model relates to originally drainage facility field, in particular to a kind of apparatus for calibrating water meter.
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
The quality of the measurement instrument of manufacture, repairing, which exercises supervision, checks that guarantees that the accuracy of factory water meter safeguards the vital interests of user
It is effective that can also comply with utility network, intelligentized development trend provides the table tool that flexibility is high, extended capability is strong
Meet the management requirement of Running-water Company and industry, but current apparatus for calibrating water meter 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 device, 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 dress is converted in order to make up for the defects of the prior art, the utility model provides a kind of flow
It sets.
The utility model is achieved by the following technical solution:
A kind of apparatus for calibrating water meter, including PLC control system, vacuum tank, meter-clamping apparatus and flow adjustment pipe, flow are adjusted
Pipeline includes three pipelines, characterized in that the internal diameter of three pipelines is different, and it is gentle to be equipped with motor-driven valve on three pipelines
Dynamic valve, connects flow initial adjustment pipeline, the flow initial adjustment pipeline is by three initial adjustment pipes in parallel between vacuum tank and meter-clamping apparatus
Road composition, the internal diameter of three initial adjustment pipelines and the internal diameter of pipeline correspond, be equipped on each initial adjustment pipeline flowmeter and
Initial adjustment pneumatic operated valve.
Three kinds of different inner diameters of three pipelines and 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 while adjusting the measurement flow of needs would not go out
Existing pervious situation fluctuated, it is easy to which the measurement flow for settling to needs mentions to calculate accurately data
The high accuracy of calibrating.
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.
In figure, 1 water tank, 2 water pumps, 3 vacuum tanks, 4 meter-clamping apparatus, 5 detection platforms, 6 flow adjustment pipes, 61 motor-driven valves, 62
Pneumatic operated valve, 63 pipelines, 7 commutators, 8 weighing containers, 9 flow initial adjustment pipelines, 91 flowmeters, 92 initial adjustment pipelines, 93 initial adjustments are pneumatic
Valve.
Specific embodiment
Attached drawing is specific embodiment of the utility model.As shown in Figure 1 to Figure 3, this kind of apparatus for calibrating water meter, 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 three 63 specifications of pipeline are respectively DN25, DN10 and DN2.5, each pipe
One motor-driven valve 61 and a pneumatic operated valve 62 are all installed on road 63, a flow initial adjustment is connected between vacuum tank 3 and meter-clamping apparatus 4
Pipeline 9, flow initial adjustment pipeline 9 are made of three initial adjustment pipelines 92 in parallel, and the specification of three initial adjustment pipelines 92 is also respectively
DN25, DN10 and DN2.5 are equipped with flowmeter 91 and initial adjustment pneumatic operated valve 93 on each initial adjustment pipeline 92.DN25, DN10 and
DN2.5 indicates that their internal diameter is respectively 25,10,2.5 millimeters,
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 retains the identical pipeline 63 of internal diameter and initial adjustment pipeline 92, after the flow value measurement of this internal diameter, then simultaneously
It closes, then opens the pipeline 63 and initial adjustment pipeline 92 of another same inner diameter, then detected.
In addition to the technical characteristic described in the specification, remaining technical characteristic is technology known to those skilled in the art.
