This pipeline fluid detection device due to feed pipe be internally provided with first-class gauge and
Return pipe is internally provided with second gauge, calculates first-class gauge and by control system
Whether there is difference between two effusion meters, finally can interpolate that out pipeline whether dehydration.
Embodiment one
The structural representation of the pipeline fluid detection device of the embodiment one that Fig. 1 provides for the present invention
Figure;Fig. 2 is the remote control module detecting device based on the pipeline fluid described in Fig. 1.
As shown in Figure 1-2, the present embodiment provides a kind of pipeline fluid detection device, including supplying water
Pipe 1, return pipe 2 and the measurement pipe 3 between feed pipe 1 and return pipe 2, feed pipe
1 is internally provided with the first-class gauge 11 that can interpolate that water (flow) direction, and return pipe 2 is internal to be arranged
There is the second gauge 21 that can interpolate that water (flow) direction, and by first-class gauge 11 and second
Difference between effusion meter 21 judges whether dehydration;
First-class gauge 11 and second gauge 21 all can carry out data biography with control system
Defeated, in order at flow information that first-class gauge 11 and second gauge 21 are collected
Reason, detects each household pipeline;
This pipeline fluid detection device is owing to being internally provided with first-class gauge 11 at feed pipe 1
It is internally provided with second gauge 21 with at return pipe 2, calculates first by control system
Whether there is difference between effusion meter 11 and second gauge 21, finally can interpolate that out pipeline
Whether dehydration.
The concrete calculating process of the flow of feed pipe 1 and return pipe 2 is: assume first-class gauge
11 instantaneous deliveries collecting certain moment feed pipe 1 are l1, second gauge 21 collects certain
The instantaneous delivery of moment return pipe 2 is l2If needing to calculate feed pipe 1 in certain a period of time
With the integrated flux (assume during this period of time for t) on return pipe 2, the most respectively by l1And l2At this
Quadrature on section time t, i.e. can get after elapsed time t on feed pipe 1 and return pipe 2
Integrated flux.It is represented by with formula: the integrated flux of feed pipe 1Backwater
The integrated flux of pipe 2Wherein t=t2-t1.Work as L2=L1Time, in feed pipe 1 not
There is phenomenon of losing water;Work as L2<L1Time, feed pipe 1 exists phenomenon of losing water, this dehydration is existing
Occur that crackle causes as being likely due to the somewhere of return pipe 2, it is also possible to be due to
The artificial water intaking at family causes.
Work as L2During for positive number:
(1) L is worked as1Slightly larger than L2Time: owing to manufacture reason or the instrument self of pipeline are deposited
Slightly detect error, it is possible that the integrated flux L of feed pipe 11Slightly larger than backwater
The integrated flux L of pipe 22Situation, owing to this error is unavoidable, therefore in reality
During use, this slight error can be ignored, and by L1Regard as and L2Equal,
I.e. there is not phenomenon of losing water on feed pipe 1.
(2) L is worked as1Much larger than L2Time: although the manufacture reason of pipeline or instrument self are deposited
Slightly detect error, L1And L2Between difference do not have the biggest deviation, very may be used
Can be to have people's water steathily or occur in that the problem that pipeline is damaged.
Work as L2During for negative:
(1) L is worked as1During equal to zero: feed pipe 1 stops supplying water, if return pipe 2 is also in water outlet
Time, then prove there is people at water steathily.
(2) L is worked as1Much larger than L2Time: although the manufacture reason of pipeline or instrument self are deposited
Slightly detect error, L1And L2Between difference do not have the biggest deviation, very may be used
Can be that someone steals water, and the water yield is very big steathily, or occur in that the problem of pipeline serious damage,
Need on-call maintenance.
Work as L2When being zero:
Feed pipe 1 is supplying water, but return pipe 2 stops backwater, then prove to be likely to be people
Stealing water or occurring in that the problem that pipeline is damaged.
As it is shown in figure 1, be provided with for showing on first-class gauge 11 and second gauge 21
Show the display screen of data message, facilitate user to be just in and can read the letter that flow meter detects
Breath, it was observed that whether there is phenomenon of losing water in oneself heat supplying pipeline, when the non-artificial situation of appearance
When causing the phenomenon that dehydration occurs in heat supplying pipeline, user can join with local heat supply company in time
System, there is the reason of phenomenon of losing water in investigation, reduces the energy and economic loss;
And first-class gauge 11 is disposed as electromagnetic flowmeter, turbine stream with second gauge 21
Gauge or ultrasonic flowmeter.
It should be noted that the first-class gauge 11 in the present embodiment and second gauge 21
Can be above-mentioned electromagnetic flowmeter, turbine flowmeter or ultrasonic flowmeter, but not only office
It is limited to these several effusion meter forms above-mentioned, it is also possible to use the effusion meter of other forms, such as,
Use vortex-shedding meter, or orifice flowmeter, as long as by the effusion meter energy of this form
The instantaneous delivery flowing through feed pipe 1 and return pipe 2 is acquired by enough realization.It addition,
Convenience and the accuracy of metering, above-mentioned first-class gauge 11 and second in view of assembling
Gauge 21 takes the effusion meter of form of the same race as far as possible.
As in figure 2 it is shown, control system includes that acquisition module, computing module 7, data process mould
Block 8 and monitoring module 10;
Acquisition module and data processing module 8 all can carry out data transmission with computing module 7.
In the alternative of the present embodiment, control system also includes real-time monitoring modular 9, in real time
Monitoring modular 9 can carry out data transmission with data processing module 8, it is possible to detection different time
The dehydration situation of section, if the fluid loss of each time period is identical, then proves conduit failure, if
The fluid loss of each time period is different, then prove have people to steal water.
In the alternative of the present embodiment, whether monitoring module 10 is for being used for monitoring return pipe 2
There is the fluid loss monitoring modular of phenomenon of losing water.
In the alternative of the present embodiment, acquisition module includes that be positioned on feed pipe 1 first adopts
