1. overcurrent pipeline in figure, 2. software capsules, 3. topping-up pumps, 4. tapping valves, 5. water feeding pressure detectable signals, 6.PLC
Controller, QIntoWater inlet end instantaneous delivery, QGo outWater outlet instantaneous delivery.
Embodiment
In Fig. 1, overcurrent pipeline not yet water, tapping valve 4 are closed, to keep water feeding pressure, in 6 foundation of PLC controller
Water feeding pressure detectable signal 5, which controls topping-up pump 3 to open to 2 filling liquid of software capsule, makes its fully expanded, seals whole pipeline overcurrent
Closed after section.Overcurrent pipeline stops completely, at this time pipeline disengaging water (QInto、QGo out) it is zero, but pipe water end hydraulic pressure etc.
In the corresponding pipeline overbottom pressure when topping-up pump 3 is closed, and water outlet hydraulic pressure is zero.
When pipe water, water inlet end hydraulic pressure increases due to there is pressure water, is protected when its hydraulic pressure increases to more than pipe network
During hydraulic pressure, PLC controller 6 controls tapping valve 4 to open according to water feeding pressure detectable signal 5, and liquid is discharged in software capsule 2
And shrink, untouched stifled pipe control section is opened, the increase of pipeline outflow, and water inlet end hydraulic pressure is due to pipeline outflow
Increase and decline, when water inlet end hydraulic pressure is equal to pipe network protection hydraulic pressure value, PLC controller 6 is controlled according to water feeding pressure detectable signal 5
Tapping valve 4 processed is closed, and software capsule 2 no longer reduces, and pipeline outflow is not further added by this time, pipeline disengaging water (QInto、QGo out) one
Cause, hydraulic pressure is equal to pipe network protection hydraulic pressure before and after software capsule 2.System is run to Fig. 2 states from Fig. 1.
When water is sufficient, instant water coming-in amount is more than instantaneous water yield, and water inlet end hydraulic pressure is increased again to be protected more than pipe network
Hydraulic pressure value is protected, PLC controller 6 controls tapping valve 4 to open again according to water feeding pressure detectable signal 5, liquid quilt in software capsule 2
Release completely and be contracted to minimum, water hydraulic pressure water is sufficient at this time, and hydraulic pressure is all higher than pipe network protection hydraulic pressure before and after software capsule 2
Value.System is run to Fig. 3 states from Fig. 2.
