The invention also provides a control method of the intelligent water leakage prevention valve, which is applied to the intelligent water leakage prevention valve and comprises three control modes, namely a normal water use working condition control mode, a drip working condition control mode and a sudden water supply working condition control mode,
The method for controlling the mode under the normal water use condition comprises the following steps: setting a single continuous water consumption threshold under a normal water consumption working condition in a controller; the reed switch sensor collects water flow data and transmits the water flow data to the controller; the controller compares the water flow data acquired by the reed switch sensor with a single continuous water consumption threshold under the normal water consumption working condition; if the collected water flow data exceeds a single continuous water consumption threshold under the normal water consumption working condition, the controller controls the water pipe on-off control valve to be closed;

The method for controlling the mode of the sudden water supply working condition comprises the following steps: setting an automatic water supplementing threshold value of the closestool under the sudden water supply working condition in the controller; the water pressure sensor detects whether water exists in the water inlet pipeline and transmits the water to the controller; if the water pressure sensor firstly transmits a water-free signal to the controller, then transmits a water signal to the controller, and the controller judges a sudden water-supply working condition; the reed switch sensor collects water flow data and transmits the water flow data to the controller; the water pressure sensor detects water pressure state data and transmits the data to the controller; if the water flow data collected by the reed switch sensor does not reach the automatic water supplementing threshold value of the closestool, the water pressure drops again and the controller judges that water is used by people; if the water pressure is stable during the period that the water flow data collected by the reed pipe sensor does not reach the automatic water supplementing threshold of the closestool, the controller judges that the water leakage phenomenon exists after the water flow data collected by the reed pipe sensor reaches the automatic water supplementing threshold of the closestool, and controls the water pipe on-off control valve to be closed. The specific embodiment is as follows: firstly, under the normal water consumption working condition control mode, a control key 10 is arranged on the controller, the control key is provided with an addition and subtraction key and a reset key, through the addition and subtraction key, a user can set a single continuous water consumption threshold under the normal water consumption working condition, the controller knows the water consumption through the reed switch sensor, the water consumption is compared with the threshold each time, the controller stops using water, the memory value can be automatically cleared for waiting for the next water consumption to be remembered, and the like. If the water consumption of the user at one time occasionally exceeds the set threshold value, the user only needs to turn off the faucet during the water consumption without resetting the set value, the controller can automatically clear the water flow signal transmitted by the reed switch sensor and memorize the water flow signal and immediately turn on the water consumption, if the water consumption of the user at one time occasionally exceeds the set threshold value, the spherical valve is closed, the reset key is needed to be manually pressed to clear the water consumption to release the valve, and the function can prevent the ageing of the indoor pipeline and the water leakage of the connected metal hose due to the burst of the water pressure high pipeline from being reduced to the minimum water leakage.
Secondly, under the drip working condition control mode, the drip metering movement can reach the drip metering standard by utilizing the drip metering movement, if a water pipeline in a user is damaged due to quality problems and the construction process, or a tap is not connected with the pipeline in place, the drip metering movement can drive a gear assembly by means of the connection of an impeller of the drip flow movement impulse movement, the gear assembly is different in size and drives a magnetic head to rotate by a proportional transmission sensing gear, a signal is output to a controller by a matching reed switch sensor, the condition that the drip is stopped by setting the number of 500 milliliters of water for two hours to be a threshold value under the condition that the controller recognizes metering, and the controller considers that the condition of micro-leakage is formed after the time and the water quantity reach the threshold value, and the electric actuator is commanded to stop water supply by manually overhauling the pipeline. At this time, the add-subtract key is pressed at the same time to release the micro-leakage closing valve, or the key is used to open or close the micro-leakage monitoring function to switch each other to use the micro-leakage.
Thirdly, under the sudden water supply condition control mode, when the collective water supply system is shut down, a water faucet is opened and forgets to close, so that a large number of water leakage accidents are prevented after water supply is started: because the product is provided with the water pressure sensor, the water pressure of the water inlet pipeline is monitored, the water pressure is lost after the water is stopped, and the controller considers that the water is stopped. After the period of time, the controller obtains an incoming water signal. At this time, no water flow flows through the movement, the reed switch sensor does not obtain a signal, the controller considers that the indoor toilet water tank is in a full water state, the faucet is in a complete closing state, and water is normally supplied indoors. If water flows through the movement at the moment of water supply, the controller knows that water supply phenomenon is carried out indoors through the reed pipe sensor, at the moment, the measured flow is set to be the threshold value which is not more than 26 liters of water within 90 seconds, the water quantity is used for considering the water consumption of the automatic water supplementing of the closestool after water supply is carried out in the water stopping period, the controller knows that water flows indoors through the reed pipe sensor when water flows into the water tank, the water pressure condition data during the automatic water supplementing period of the indoor closestool is monitored and analyzed through the water pressure sensor, and the water pressure during the automatic water supplementing period of the closestool is considered to be the water consumption of a person when the water tap of the multi-branch water pipe is opened by the controller. The water pressure is stable and does not drop again during automatic water supplementing of the closestool, when the inflow indoor water quantity exceeds a threshold value, the controller considers that the indoor faucet is not closed, the water leakage phenomenon exists, and the controller commands the electric actuator to close the spherical valve to stop water supply, so that misjudgment that water is just used by people when the automatic water supplementing of the closestool is performed is accurately analyzed. Under normal conditions, the national standard water-saving closestool can fully fill the indoor pipe in the time and the water quantity until no water is fed. The controller no longer obtains the rivers signal that the tongue tube transmitted and considers indoor water valve to close normally, later has rivers to flow through and regard as indoor someone to use water, guarantees water safety through the single water consumption that the user set for by oneself.
According to the intelligent leakage-proof water valve and the control method thereof, the reed switch sensor and the matched magnetic block are used as the metering sensing device, the magnetic block is arranged on the sensing gear, the detection is more sensitive, the dripping water inlet hole is arranged, and under the condition of dripping, even if the impeller rotates slowly, the driven sensing gear is slower, and the reed switch sensor can also perform sensitive detection; the water inlet pipeline is provided with a water pressure sensor which can detect whether the water pressure exists or not and the water pressure, and transmits a water existence signal and water pressure state data to the controller; the water leakage inlet hole is arranged, when the water flow is small and the water flow is slow enough to enter the normal water inlet, the water enters the impeller box through the water leakage inlet hole, the impeller is pushed to rotate, and the detection of the water leakage flow is realized; the diversion filter cover can filter water entering the impeller box on one hand, and on the other hand, the circular pressing piece is arranged, the water flow impacts the circular pressing piece, and the circular pressing piece can guide and disperse the water flow around, so that the water flow can flow into a normal water inlet in a concentrated and smooth way; the controller judges the on-off state of the water pipe on-off control valve according to the state of the water pressure sensor and the acquired data of the reed pipe sensor to realize detection and control of various water conditions, for example, the single continuous water consumption threshold under the normal water consumption working condition is set, the single continuous water supply is quantitatively controlled to ensure normal water consumption of people, the water flow threshold under the drip working condition and the single water consumption threshold under the sudden water consumption working condition are set, the water consumption can be controlled when water drip or accidental water running occurs, the valve is automatically turned off in time, large loss caused by overlarge water consumption to a water consumption place is avoided, the detection is sensitive, and the automatic control level is high.
