Abstract
The invention discloses a method for detecting the water leakage of a tap water pipeline. The method comprises the following steps of: mounting a flow measurement device on the tap water pipeline; setting flow measurement time T; when an instantaneous flow in the flow measurement time T is larger than 0, recording a smallest flow Q1 in the period of time; carrying out the same calculation in next flow measurement time T; when a smallest flow Q2 larger than 0 also exists in the second period of time, and the change rate of the Q1 and the Q2 is +/- 10 percent, judging that the tap water pipeline leaks water; when the smallest flow Q2 in the second period of time is 0, returning all calculations to zero, renewedly calculating and judging, and circulating in turn. The method has the advantages of wide identification range, low cost, convenience for mounting, high identification precision and the like; and the leakage of the tap water pipeline can be timely and accurately detected.
Description
Technical field
The present invention relates to a kind of method detecting water leakage of tap water pipeline.
Background technology
Average family water is easy to just drainage occur, as toilet, sun power etc.The use water user such as general finds it is occurred and produced huge loss (as finishing wall damage, huge water rate etc.).
Technical scheme commonplace at present installs pressure transducer additional on in-service pipeline, and the change value of pressure recorded by pressure transducer carries out judging whether to leak.
Such scheme has its own shortcomings:
1, reaction is slow: because pressure change is a very complicated evolution process, the pressure change caused for leaking needs a large amount of data and time to confirm, often for the reaction needed of leaking measurements and calculations over a long time, and the consequence of now leaking often occurs.
2, expensive: to install high-precision pressure sensor additional due to needs and be equipped with background control system, therefore its price is very high.
3, precision is low: because the sensitivity of the main depended on pressure sensor of the degree of leaking realizes, therefore, requirement for pressure transducer is just very high, but price decision its can not use high-precision sensor on a large scale, therefore the sensor accuracy in market is all lower, so, for tiny infiltration, None-identified.
4, discrimination is low: because its precision comparison is low, determines it to paroxysmal large discharge seepage, and e.g., booster etc., can be very sensitive, but just relatively sluggish for low discharge, for a long time seepage.
Summary of the invention
The object of the invention is whether have lasting flow this characteristic to provide a kind of method of detection water leakage of tap water pipeline based on electronic water meter with fluid-velocity survey function according to leaking with water-tight existence for the defect of prior art.
The present invention for achieving the above object, adopts following technical scheme:
Detect a method for water leakage of tap water pipeline, its scheme is as follows: on water supply pipe, install flow measurement device, and setting flow measurement time T, when instantaneous delivery is greater than 0 in flow measurement time T, records the minimum flow Q in this time period
1, in next flow measurement time T, do same calculating, when also have in second time period one be greater than 0 minimum flow Q
2, and Q
1, Q
2rate of change <10% time be then judged as leaking; Minimum flow Q within second time period
2when being 0, all calculating returns 0, restarts to calculate, judge, circulates successively.
Preferred: described flow measurement time T is 10-20 minute.Whether this time period is the optimization carried out for user's water habits, can ensure that the time detected is quick, can detect accurately again and leak.
The present invention has the following advantages:
1, identification range is wide; From drop seep water pipeline breaking produce large discharge leak, all can realize at short notice identify, and and alarm;
2, cheap; Realize this function by the water meter that original pipeline is installed, increase any cost hardly;
3, easy for installation; The water meter used with every household is integral type, realizes installing while water pump composite;
4, accuracy of identification is high.All warning function can be realized in time for long trickle seepage or sudden booster.
Embodiment
A kind of method of the detection water leakage of tap water pipeline based on the electronic water meter with flow measurement function uses the flow metering functional realiey measurement seepage of water meter.Its scheme is as follows:
1, on the basis of original electronic water meter, discharge fluid-velocity survey function is increased.
2, the judgement to percolating water is realized by the change of calculated flow rate value.
3, the principle judged is: when the instantaneous delivery in the time T set all is greater than 0, record the minimum flow Q in this time period
1, the next one setting time T in do same calculating, now, do a judgement, when also have in second time period one be greater than 0 minimum flow Q
2, and Q
1, Q
2rate of change <10% time we are judged as leaking; When the minimum flow in second time period is 0, all calculating returns 0, restarts to calculate, judge, circulates successively.
Preferred T is 10-20 minute.
Claims (2)
