It is shown, including first flow monitor 4, second flow monitor 5, control device 7, movement device 3 constitute.
As shown in figure 1, wherein, the upstream 1 that the first flow monitor 4 is arranged on water supply line is used to monitor feed pipe
The flow of reclaimed water, and the frequency generator 8 in control device 7 is transmitted a signal to, obtain the traffic conditions of upstream current, second
Flow monitor 5 be arranged on water supply line downstream 2, due to pipe downstream current pressure reduction cause gained signal compared with
It is weak, so the signal of second flow monitor 5 needs to carry out the amplification of signal by amplifier 6, it is then fed to counter
9.Comparator 10 is contrasted the signal from frequency generator 8 and counter 9, is preset if both signal differences are more than
Accumulative difference or the difference duration exceed the default time, then comparator 10 will to electromagnetic relay 11 send letter
Number, movement device is started and is closed valve to prevent the leakage of current.Flow monitor can use pressure sensor,
Spinner flowmeter or other suitable flow monitoring means.
In the specific implementation example of the present invention, movement device 3 is an electronic valve or operated pneumatic valve, is worth noting
Be that other forms such as sound or visual alarm can also be used to substitute valve in the application.For example when comparator 10
Monitor that siren can be sent a signal to during water pipe leak so that the operator on duty at position knows farther out, so as to take
Artificial measure manual-lock valve simultaneously carries out checking that pipeline whether there is other problemses.
In the specific implementation example of the present invention, first flow monitor 4 sends signal to control device 7, and monitors
The flow of in-pipe flow.Actual leak time and default time are considered as a meeting point by control device 7, and will actually be let out
Leakage quantity and default leakage rate are considered as a meeting point.For the monitoring error for preventing the reasons such as some flow losses from causing, in reality
Border is measured can set some safety coefficients when being compared with predetermined amount, to prevent flow losses from causing control device to judge by accident.When
When actual leak time or actual leakage rate exceed preset value, control device 7 determines that pipeline is leaked or abnormal
