Present embodiment also relates to and water purifier 2 matching used water Leak testtion and controlling methods, specifically may further comprise the steps:
When logical water purifier 2 was normally intake, second control circuit board, 22 control inlet valves 21 were by the keying rule keying of setting;
Detect flow, pressure or the flow velocity change with time of water in the intake pipe 4 through sensor 32; Sensor 32 compares water flow, pressure or the flow velocity rule of conversion set in flow, pressure or the change in flow rule of water in the detected intake pipe 4 and first control circuit board 33 for first control circuit board, 33, the first control circuit boards 33 detected data transmission number;
When flow, pressure or the change in flow rule of water in the detected intake pipe 4 meets the water flow set in first control circuit board 33, pressure or change in flow rule; First control circuit board 33 judges that water purifier 2 is normal water inlet, and water source valve 31 is held open;
When flow, pressure or the change in flow rule of water in the detected intake pipe 4 do not meet the water flow set in first control circuit board 33, pressure or change in flow rule; First control circuit board 33 judges that the intake pipe 4 of water purifier 2 or water purifier 2 leak, and first control circuit board 33 is closed water source valve 31.
Open and close for ease of first control circuit board, 33 control water source valves 31, water flow, pressure or the flow velocity rule of conversion of setting in said first control circuit board 33 is corresponding with the control inlet valve 21 keying rules that second control circuit board 22 is set.
When water purifier 2 normal water inlets; The signal that second control circuit board 22 sends setting makes inlet valve 21 carry out opening and closing according to particular requirement; Close after for example opening for 5 seconds, continue to close after 5 seconds and open once more, flow, pressure or the change in flow rule of water meet water flow, pressure or the change in flow rule of setting in first control circuit board 33 in the sensor 32 detected intake pipes 4; First control circuit board 33 judges that water purifier 2 is normal water inlet, and water source valve 31 is held open;
When water purifier 2 intake pipes 4 break, pipe joint breaks or other reason causes the intake pipe 4 tunnel of water purifier 2 to leak or water purifier 2 leaks; Flow, pressure or the change in flow rule of water do not meet water flow, pressure or the change in flow rule of setting in first control circuit board 33 in the sensor 32 detected intake pipes 4; First control circuit board 33 judges that water purifier 2 intake pipes 4 or water purifier 2 leak, and first control circuit board 33 is closed water source valve 31.
When inlet valve 21 is solenoid valve, second control circuit board, 22 control inlet valves, 21 keying rule examples by setting:
A. inlet valve 21 opens and closes rule: close after opening for 5 seconds, open once more after 5 seconds that kept shut, the state that is held open is closed inlet valve 21 after inflow meets the requirements;
The keying rule of b. above-mentioned inlet valve 21 is corresponding to the variation in water pressure rule in the intake pipe 4: intake pipe 4 internal pressures transfer low-pressure state (water inlet) to by high pressure conditions (stopping into water) and transfer high pressure conditions (stopping into water) again to after lasting 5 seconds; Keep high pressure conditions (stopping into water) to continue to transfer low-pressure state (water inlet) again to after 5 seconds, keep low-pressure state (water inlet) after inflow meets the requirements, to close inlet valve 21.
The keying rule of c. above-mentioned inlet valve 21 is corresponding to water flow or change in flow rule in the intake pipe 4: water flows are transferred to being not less than by 0 flow or 0 flow rate regime (stopping into water) and set flow or flow rate regime (water inlet) transfers 0 flow or 0 flow rate regime (stopping into water) to after lasting 5 seconds in the intake pipe 4; Transfer to after 0 flow or 0 flow rate regime (stopping into water) keep continuing for 5 seconds being not less than and set flow or flow rate regime (water inlet), maintenance is not less than the setting flow or flow rate regime (water inlet) is closed inlet valve 21 after inflow meets the requirements.
D. for above-mentioned example; First control circuit board 33 judges that whether the intake pipe 4 tunnel of water purifier 2 leaks the required time is 5-10 second; Promptly if intake pipe 4 internal pressures (or flow or flow velocity) that cause owing to the pipe-line system leakage change; Technology then of the present invention can find that first control circuit board 33 signals immediately the water source is closed after at leakage 5-10 after second, prevent to continue to leak to result in greater loss.
E generally speaking, water purifier 2 can be above 10 minutes through the water inlet duration of intake pipe 4 water inlet in one day (24 hours).If water purifier 2 is in the normal water inlet section and an intake pipe 4 takes place leaks, then an embodiment of the present invention's technology can not find.But if a large amount of the leakage taken place in other period, then the present invention's technology can be found in second at 5-10, promptly only can leak 5-10 second, first control circuit board 33 just can be closed the water source valve 31 tunnel on the intake pipe 4, sends sound and/or light simultaneously and reports to the police.With 10 minutes as molecule; With 24 hours (1440 minutes) as denominator; Its ratio approximates 0.69%, and this ratio can be used as can not find the probability that leaks, and technology promptly of the present invention can solve because of intake pipe 4 breaks and cause 99.31% of a large amount of these problems of leakage.
And inlet valve 21 is when being mortor operated valve, and second control circuit board, 22 control inlet valves 21 are by the keying rule examples of setting:
Said inlet valve 21 has the motorized adjustment function; The valve that is inlet valve 21 can be according to the Changing Pattern of the control signal of second control circuit board 22 aperture of regulating valve automatically; Thereby change water flow makes the consistent time dependent rule of pressure of time dependent rule of intake pipe 4 internal pressures and setting that perhaps makes with the time dependent rule of the flow of setting of the time dependent rule of in-pipe flow amount consistent.For this situation; The water inlet of water purifier 2 is all carried out according to pressure or the time dependent rule of flow set; As long as intake pipe 4 leaks, in the intake pipe 4 that sensor 32 detects the flow of water greater than zero and flow or pressure do not meet the time dependent rule of setting, first control circuit board 33 just can judge that intake pipe 4 tunnel leaks; Just close water source valve 31 immediately, send acoustooptic alarm simultaneously.This design proposal can solve because of intake pipe 4 ability that causes a large amount of these problems of leakage of breaking and almost reach 100%.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm its technical protection scope according to claims.
