Lower check bit is not in when being flooded by the water surface or be not exposed to leak, and contact A and contact B are off, triode
Base stage no current inputs, and triode cut-off, relay coil no current flows through, then the movable contact of relay still with normally-closed contact
Contact, the connection of electrically operated valve valve opening line, motor-driven valve is in opening state, does not interfere with the unobstructed of flow in pipeline；Once contact A
Safe water bit line or the unicom due to ground leak are touched with contact B, transistor base input current, triode saturation, by
It is connected in the collector of relay coil and triode, therefore there is sizable electric current to flow through in relay coil, then relay
It is attracted, the movable contact for showing as relay is contacted with normally opened contact, and the pass line valve line connection of electrically operated valve, electrically operated valve is in
Closed state can immediately block flow, prevent from continuing leak.So electrically operated valve need to be only mounted at main valve, it will
Contact, which is mounted on, needs the position of sensed water level or leakage point, once indoor generation leak, the utility model can judge in time be
No leak and the water source for cutting off main valve, while the technical solution of utility model is at least provided with one group of test contact, every group of test
All it is parallel with one another between contact, test contact can be distributed in many places for needing to monitor water leakage situation, to real in house
Existing multi-point monitoring causes house to lose so as to solve the problems, such as generation leak after house nobody or night people are fast asleep.
Further, the utility model further includes alarm mechanism, and the alarm mechanism includes light emitting diode and current limliting electricity
Resistance, the power supply are DC power supply, the emitter of triode and the other end of relay coil respectively with the cathode of power supply
It is connected with anode, the light emitting diode is connected between the normally opened contact of relay and power cathode, and the hair
Optical diode is directly in series with current-limiting resistance with relay.
Through the above technical solutions, the utility model is also provided with alarm mechanism, the light emitting diode connection of alarm mechanism
Between the normally opened contact and power supply of relay, once the normally opened contact of relay is attracted, light emitting diode can emit beam
Alarm reminds resident to close tap or investigation leak source.
Further, the utility model further includes buzzer, and the buzzer is connected on power supply and the normally opened of relay touches
Between point.
Through the above technical solutions, the utility model is connected to buzzer between power supply and the normally opened contact of relay,
Both it can individually alarm, alarm mechanism can also be combined, also, in the technical program together as acousto-optic with light emitting diode
