Description
Technical field
The present invention relates to instrument and meter detection technique fields, and in particular to one kind is leaked for town dweller's heating network dehydration
Water judges system and method certainly.
Background technology
Town dweller's heat supply belongs to the livelihood issues that China attaches great importance to, and heating network is because of construction problem, usage time
The problems such as long problem, bad environments variation, can all pipe network be caused to damage, heating medium is caused to be lost in, and then cause resident house
Parasitic losses inside front yard.Meanwhile what is brought is that heat supply relevant departments service quality declines, customer satisfaction declines.
The settling mode of conventional heating network dehydration or leak is：Heat supply service unit is voluntarily reported by resident, is supplied
Hot service unit carries out the valve that resident's heat supply is turned off manually, can not effectively, solve problems in real time.
Therefore, for the development of current heating industry technology, and with more and more concerned livelihood issues, how to have
The case where effect, quick, safety solution heating network dehydration leak, meanwhile, the damage of heat supply service unit is reduced to the greatest extent
It loses, resident's parasitic losses caused by leak, is a technical problem for being badly in need of solving.
Invention content
The present invention provide a kind of town dweller's heating network dehydration leak from judgement system, solve existing heating system
The problem of middle dehydration leak can not be handled quickly and effectively.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of town dweller's heating network dehydration leak from judging system, including：
For the motor-operated control valve on/water return pipeline and the metering for measuring flow in town dweller's heating network
Table, and data acquisition device is connected via wire or wirelessly between motor-operated control valve and gauge table, data acquisition dress
It sets the data for obtaining motor-operated control valve and gauge table and controls motor-operated control valve.
The present invention also provides a kind of town dweller's heating network dehydration leaks from judgment method, including：
An instantaneous flow threshold value of warning is set on data acquisition device, by data acquisition device, reads meter in real time
The instantaneous flow value of scale is simultaneously compared with the instantaneous flow threshold value of warning of setting；If the instantaneous flow value of current gauge table is small
In the instantaneous flow threshold value of warning equal to setting, then data acquisition device continues digital independent and compares, if current metering
The instantaneous flow value of table is more than the instantaneous flow threshold value of warning of setting, then data acquisition device issues the finger for closing motor-operated control valve
It enables.
Further, the maximum value of the instantaneous flow threshold value of warning≤Q- Δ Q, the minimum value of instantaneous flow threshold value of warning
The minimum leakage amount that >=Q- flowmeters can measure；
The Q is flow in pipeline, and calculation formula is as follows：
Wherein H is pipe ends head difference, and s is resistivity, and L is duct length, and Δ p is pipe ends pressure difference, and ρ is that medium is close
Degree, g are acceleration of gravity, and h is that both ends duct height is poor, and d is pipe diameter；
The Δ Q is variable flow, and calculation formula is as follows：
Wherein, α is yearly variation.
Preferably, after the motor-operated control valve is closed, back information to data acquisition device, data acquisition device continue into
The read work of row gauge table instantaneous flow value, meanwhile, it is preserved for current failure processing information.
Further, after the motor-operated control valve on water return pipeline being closed, if the flow value of the gauge table on water supply line
It is not zero and then there is leakage.
By above technical scheme it is found that whole system framework of the present invention is simple, reasonable design quickly and can be solved effectively
The problem of dehydration and leak that certainly resident occurs in heat supplying process.
Description of the drawings
Fig. 1 is the systematic schematic diagram that the present invention judges system certainly.
Specific implementation mode
A kind of preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, town dweller's heating network dehydration leak from judgement system include motor-operated control valve 1, gauge table 2
With data acquisition device 3, wherein motor-operated control valve and gauge table is mounted in confession/water return pipeline in town dweller's heating network
On.The gauge table uses heat energy meter or flowmeter, mainly realizes heat metering, and records and preserve related data, such as tired
Count flow etc..By wired or wireless connection between the data acquisition device and motor-operated control valve and gauge table, mainly in fact
The data interaction of existing gauge table, motor-operated control valve, completes the reading and comparison of instantaneous flow, completes the control to motor-operated control valve
Order issues automatically.
The present invention is based on above-mentioned a kind of town dweller's heating network dehydration leak is also provided from judgement system from judgment method,
Specifically comprise the following steps：
An instantaneous flow threshold value of warning is set on data acquisition device, by data acquisition device, reads meter in real time
The instantaneous flow value of scale is simultaneously compared with the instantaneous flow threshold value of warning of setting；If the instantaneous flow value of current gauge table is small
In the instantaneous flow threshold value of warning equal to setting, then data acquisition device continues digital independent and compares, if current metering
The instantaneous flow value of table is more than the instantaneous flow threshold value of warning of setting, then data acquisition device issues the finger for closing motor-operated control valve
It enables.
The instantaneous flow threshold value of warning uses interval value, and maximum value≤Q- Δ Q, minimum value >=Q- flowmeters can
The minimum leakage amount of measurement, wherein Q are flow in pipeline, and Δ Q is variable flow.
There are friction loss and local resistance loss in pipeline, and since pipeline is longer, local resistance loss can be ignored,
Therefore flow Q can be calculated as follows in pipeline：
Wherein H is pipe ends head difference, and s is resistivity (being calculated using She Weilie formula), and L is duct length, and Δ p is pipe
Road both ends pressure difference, ρ are Media density, and g is acceleration of gravity, and h is that both ends duct height is poor, and d is pipe diameter.
According to the present embodiment, unique variable is regarded as the resistance of pipeline, over time, inner wall of the pipe friction
Increase, is reduced to caliber reduction, it is assumed that yearly variation α is 0.0005m, then there is variable flow Δ Q is：
Wherein, α is yearly variation, preferably 0.0005m.
Size according to instantaneous flow threshold value of warning is tentatively to judge, it is understood that there may be the false alarm of official website instability of flow,
After the closing of the motor-operated control valve on water return pipeline pipe leakage can be judged again, if the flow of the gauge table on water supply line
Value, which is not zero, then has leakage.
, can be with back information to data acquisition device after motor-operated control valve closing, data acquisition device continues to count
The read work of scale instantaneous flow value, meanwhile, it is preserved for current failure processing information.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
It encloses and is defined, under the premise of not departing from design spirit of the present invention, technical side of the those of ordinary skill in the art to the present invention
The various modifications and improvement that case is made should all be fallen into the protection domain of claims of the present invention determination.
