Row, which turns off the switch valve, to be stopped supplying water and sounding an alarm, to reduce property loss caused by leak.This scheme can be used for small stream
Measure the judgement of infiltration state and protection.
For example, when flow detector detects the water flow by flow detector, lower than the flow of peak flow 20%
When, the case where continuing flow 1 minute, is considered as with water exception, and activation system early warning issues commands to valve by controller and executes
Device 5 drives valve regulated bar 4 to turn off the shutdown of opening/shutting valve 3 and opens 1 minute within 5 seconds while being sounded an alarm again by loudspeaker horn 13
Hurriedly flashing issues audible and visible alarm for sound and operating status lamp 18, and user is using, and full pass can be taken to be beaten again with penstock 2 seconds
It opens, flow detector, which monitors to have by the water flow of flow detector, arrheas parameter, is transferred to controller, and controller issues
It orders and drives valve regulated bar 4 to open opening/shutting valve 3 to valve actuator 5, and release acousto-optic early warning, water system normal use.
If it is there is water leakage situation, flow detector, which does not monitor to have by the water flow of flow detector, arrheas parameter, has crossed 1
After minute, controller issues commands to valve actuator 5 and valve regulated bar 4 is driven to turn off the stopping water supply of opening/shutting valve 3, continuation sound
Light alarm could release alarm, normal water supply until user is manually pressed by 15 control buttons or protection open-close bond 22.
In another scheme, the water flow that the flow detector detects is higher than the default percentage of single maximum stream flow
Than when, the controller controls the switch valve and closes, and controls after the alarm sounds an alarm, by second it is default when
Between, it controls the switch valve and opens, whether the flow detector detects in third preset time has in the pipeline of water system
Arrhea, if so, it is in the open state then to control the switch valve, and sound all clear, if nothing, controls the switch valve and be in pass
Closed state continues to sound an alarm.This scheme can be judged and be protected with big flow leak state.
For example, flow detector, which is detected, records single before being more than by the continuous water flow of single of flow detector
Maximum stream flow 10% is considered as with water exception, and activation system early warning issues commands to valve actuator 5 with movable valve by controller
Adjusting rod 4 turns off opening/shutting valve 3 and turns down 70% flow 30 seconds, then turns off and open again within 5 seconds 1 minute, while passing through loudspeaker horn 13
Sounding an alarm sound and operating status lamp 18, hurriedly flashing issues audible and visible alarm, and user is using, and can take full pass water valve
Door is opened for 2 seconds again, and flow detector, which monitors to have by the water flow of flow detector, arrheas parameter, is transferred to controller,
Issuing commands to valve actuator 5 drives valve regulated bar 4 to open opening/shutting valve 3, and releases acousto-optic early warning, and water system normally makes
With.If it is there is water leakage situation, flow detector, which does not monitor to have by the water flow of flow detector, arrheas parameter, mistake
Controller, which issues commands to valve actuator 5 valve regulated bar 4 is driven to turn off opening/shutting valve 3, after 1 minute stops supplying water, continue
Sound-light alarm could release alarm until user is manually pressed by control button 15 or protection open-close bond 22, resume water supply.
Above scheme can be also used for the detection and protection of non-normal hours internal water system system leak, in preset period in advance
The water period of user is detected, which is positive the common water time, remaining time is improper with the water time.It is non-just
In the common water time, flow detector is detected by water flow, and the water flow that the flow detector detects is higher than single
When the preset percentage of secondary maximum stream flow, the controller controls the switch valve and closes, and controls the alarm and issue police
After report, by the second preset time, controls the switch valve and open, the flow detector detects water in third preset time
Whether have in the pipeline of system and arrhea, if so, it is in the open state then to control the switch valve, and sound all clear, if nothing, controls
It makes the switch valve to be in close state, continues to sound an alarm.
For example, not use water system as unit of hour in 2 cycles, being considered as non-with 2 weeks for a cycle
The just common water time, when flow detector monitors there is water flow parameter by flow detector during the non-time with water,
It is transferred to controller, activation system early warning issues commands to valve actuator 5 by controller and valve regulated bar 4 is driven to turn off
Opening/shutting valve 3 turns down 70% flow 30 seconds, then turns off and open again within 5 seconds 1 minute, while being sounded the alarm by loudspeaker horn 13
Hurriedly flashing issues audible and visible alarm for sound and operating status lamp 18, and user is using, and full pass can be taken to be beaten again with penstock 2 seconds
It opens, flow detector, which monitors to have by the water flow of flow detector, arrheas parameter, is transferred to controller, issues commands to
Valve actuator 5 drives valve regulated bar 4 to open opening/shutting valve 3, and releases acousto-optic early warning, water system normal use.If it is
There is water leakage situation, flow detector, which does not monitor to have by the water flow of flow detector, arrheas parameter, after having spent 1 minute
Controller issues commands to valve actuator 5 and valve regulated bar 4 is driven to turn off the stopping water supply of opening/shutting valve 3, continues sound-light alarm,
Alarm could be released until user is manually pressed by control button 15 or protection open-close bond 22, is resumed water supply.
In more optimal solution, leak state of setting up defences, Yong Hu can also be arranged in water system protective device provided by the invention
Start leak state of setting up defences before going out, user cancels leak state of setting up defences after going home, deactivation system is protected, then during this, if stream
Amount detector detects that by the continuous water amount of flow detector be more than predetermined time period, and controller then judges different with water
Often, controller control switch valve is in close state, and is sounded an alarm.
For example, user presses the open-close bond 23 of setting up defences of wireless switching panel 20 when going out, activation system armed state, if
It sets status lamp 17 to light, the open-close bond 23 of setting up defences that user goes home to press wireless switching panel 20 again is withdrawn a garrison, and deactivation system is protected
Shield.In this process, flow detector monitors that by the continuous water flow of flow detector be more than 10 seconds, and controller is sentenced
It is abnormal with water for breaking, and issues commands to valve actuator 5 and valve regulated bar 5 is driven to turn off the stopping water supply of opening/shutting valve 3, continuation sound
Light alarm could release alarm until user is manually pressed by control button 15 or protection open-close bond 22, resume water supply.
