According to the utility model discloses detection protection method that leaks of second aspect embodiment, including following step: detecting the pressure in two sections of pipelines with different pipe diameters and communicated with each other in the water inlet pipeline; and when the time of the continuous pressure difference of the two pipelines exceeds a first preset time, controlling the valve on the water inlet pipeline to be closed.

By the detection method, the water leakage protector can detect whether the pipeline leaks water or not in a pressure detection mode under the condition that a user does not close the water outlet end of the water inlet pipeline. Specifically, the first pressure sensor 210 is disposed on an inner sidewall of the first pipe 110, the second pressure sensor 220 is disposed on an inner sidewall of the second pipe 120, pipe diameters of the first pipe 110 and the second pipe 120 are different, and the valve module 300 is disposed between the first pressure sensor 210 and the second pressure sensor 220. When no water is used by a user or no water leakage occurs in the water inlet pipeline, the liquid in the water leakage protector is static, the pressure in each position in the first pipeline 110 is equal to that in each position in the second pipeline 120, and the values detected by the first pressure sensor 210 and the second pressure sensor 220 are equal; when a user leaks water by using water or the water inlet pipeline, liquid can continuously pass through the first pipeline 110 and the second pipeline 120, because the pipe diameter of the first pipeline 110 is different from that of the second pipeline 120, the speed of the liquid when the liquid passes through the first pipeline 110 is different from that of the liquid when the liquid passes through the second pipeline 120, and according to the bernoulli equation, when the liquid passes through the water leakage protector, the pressure of the liquid on the first pipeline 110 is different from that of the liquid on the second pipeline 120, that is, a pressure difference occurs between the first pipeline 110 and the second pipeline 120, and the pressure detected by the first pressure sensor 210 is different from that detected by the second pressure sensor 220. When the pressure difference occurs, the control module controls the timing device to time the duration of the pressure difference. When the duration time of the pressure difference exceeds the first preset time of the timing device, the control module can judge that the water inlet pipeline leaks water, further control the valve module 300 to be closed, cut off the communication between the water supply pipeline and the water inlet pipeline, and clear the timing device; when the duration time of the pressure difference does not exceed the first preset time of the timing device, the control module can judge that the water inlet pipeline does not leak water, and the timing device is reset. The user can set up timing device's first preset time through control module group to adapt to different water use occasions, prevent that the user from judging the inlet channel in water use in-process control module group mistake and leaking, and then cut off the intercommunication influence user's normal water of inlet channel and water supply pipe, for example, first preset time in the timing device is 5 minutes, if user's once-through water time needs to exceed 5 minutes, alright with first preset time extension through control module group.

In some embodiments of the present invention, the valve on the control water inlet pipe is closed, specifically, the control valve is partially closed first, when two sections the time that the pipe still continuously has the pressure difference exceeds the second preset time, the valve on the control water inlet pipe is completely closed, otherwise the valve on the control water inlet pipe is completely opened.

Through the detection method, the water leakage protector can remind a user when the water consumption of the user exceeds the first preset time. Specifically, the timing device is further provided with a second preset time in addition to the first preset time, when the water consumption time of the user exceeds the first preset time in the timing device, the control module controls the valve module 300 to be partially closed, and the timing device continues to time the pressure difference duration. After the valve module 300 is partially closed, the user can clearly feel that the water outlet flow of the water inlet pipeline is reduced. At this time, the user only needs to temporarily close the water outlet end of the water inlet pipeline within a second preset time, so that the liquid in the water leakage protector stops flowing, the pressure difference between the first pipeline 110 and the second pipeline 120 disappears, the control module can judge that no water leakage occurs in the pipeline, the valve module 300 is completely opened, the water outlet flow of the water inlet pipeline can recover to a normal value, and meanwhile, the timing device is reset; if the water inlet pipeline leaks, when the duration time of the pressure difference exceeds the first preset time and the second preset time, the control module can control the valve module 300 to be completely closed, the communication between the water inlet pipeline and the water supply pipeline is cut off, and the timing device is reset. Compared with a water leakage protector without the second preset time, the method can remind the user when the water using time of the user exceeds the first preset time, and the user can be prevented from misjudging that the water inlet pipeline leaks water and then closing the valve module 300 to influence normal water use of the user by only temporarily closing the water outlet end of the water inlet pipeline and resetting the timing device after being reminded, so that the convenience of the user in long-time water use is improved.

In some embodiments of the present invention, the water leakage detection and protection method further comprises the following steps: and after the valve is closed, detecting the pressure change of the water inlet pipeline within a third preset time, if the pressure continuously drops and/or the pressure drops beyond a preset value, keeping the valve closed, otherwise, controlling the valve to be opened.

Through the above detection method, the second pressure sensor 220 can perform pressure detection on the water inlet pipe again after the valve module 300 is closed to determine whether water leakage occurs, so that the detection accuracy is further improved. Specifically, after the control module determines that the water inlet pipe leaks and controls the valve module 300 to close, the control module also controls the second pressure sensor 220 arranged behind the valve module 300 to detect the pressure in the water inlet pipe within a period of time, and determines whether the water inlet pipe leaks again according to the detection result of the second pressure sensor 220. If the second pressure sensor 220 detects that the pressure in the water inlet pipe is kept stable within a third preset time, the control module can judge that no water leakage occurs in the water inlet pipe, and the control module can control the valve module 300 to open; if the second pressure sensor 220 detects that the pressure in the water inlet pipe continuously decreases or the pressure change exceeds a preset value within a third preset time, the control module determines that water leakage occurs in the water inlet pipe and keeps the valve module 300 closed. According to the water leakage detection and protection method, whether the water inlet pipeline leaks or not is judged in advance by detecting whether the pressure difference and the pressure difference duration time exist between the two pressure sensors or not, then the valve module 300 is closed when the water leakage is judged in advance, and whether the water inlet pipeline leaks or not is judged by detecting the pressure in the water inlet pipeline for a period of time through the second pressure sensor 220, so that the accuracy of water leakage detection of the water leakage protector is effectively improved through double detection.

In some embodiments of the present invention, the valve is disposed between the two sections of pipes, and when any one pressure value of the two sections of pipes is detected to exceed a preset maximum value, the valve is controlled to close; and when the pressure value detected in the pipeline at the front side of the valve is lower than the preset maximum value, controlling the valve to be opened.

By the detection method, the water inlet pipeline can be effectively prevented from being damaged due to overhigh water pressure in the water inlet pipeline. Specifically, be equipped with a high pressure protection value in the control module group, first pressure sensor 210 and second pressure sensor 220 continuously detect the inside pressure of casing, and the control module group gathers the pressure numerical value that first pressure sensor 210 and second pressure sensor 220 detected in real time. When the pressure in the water supply pipeline is increased, the pressure in the shell is also increased. When casing internal pressure is greater than the high pressure protection value, first pressure sensor 210 or second pressure sensor 220 detect when intake pipe internal pressure is greater than the high pressure protection value, and control module just can control valve module 300 and close, cuts off the intercommunication of intake pipe and water supply pipe, prevents that liquid from entering into the intake pipe and rising bad intake pipe. After the valve module 300 is closed, the first pressure sensor 210 arranged at the front end of the valve module 300 continuously detects the internal pressure of the first pipeline 110, and when the pressure detected by the first pressure sensor 210 is smaller than a high-pressure protection value, the control module can control the valve module 300 to be opened, so as to recover the communication between the water inlet pipeline and the water supply pipeline. If the water leakage protector has detected that water leakage has occurred in the water inlet pipe and the valve module 300 is closed, the valve module 300 is not opened even if the first pressure sensor 210 detects that the internal pressure of the first pipe 110 is less than the high pressure protection value.

When a user leaks water or water in a pipeline, liquid continuously flows through the water leakage protector, because the diameter of the first pipeline 110 is larger than that of the second pipeline 120, the flow rate of the liquid in the first pipeline 110 is smaller than that of the liquid in the second pipeline 120, which can be obtained according to the bernoulli equation, that is, the pressure of the liquid on the first pipeline 110 is larger than that of the liquid on the second pipeline 120, the pressure detected by the first pressure sensor 210 is larger than that detected by the second pressure sensor 220, and a pressure difference occurs between the first pipeline 110 and the second pipeline 120. The timing device is provided with a first preset time and a second preset time, the timing device starts timing after the pressure difference occurs between the first pipeline 110 and the second pipeline 120, and if the duration time of the pressure difference exceeds the first preset time or the second preset time, the control module can judge that the pipeline is likely to leak water. Specifically, when the duration time of the pressure difference does not exceed the first preset time of the timing device, the control module judges that the water inlet pipeline is not leaked, and the timing device is reset; when the pressure difference duration time exceeds the first preset time of the timing device, the control module judges that the water inlet pipeline is likely to leak water, the control module controls the valve module 300 to be partially closed, the water outlet flow of the water inlet pipeline is reduced, and the timing device counts the part of the pressure difference duration time exceeding the first preset time again. When the part of the pressure difference duration time exceeding the first preset time does not exceed the second preset time of the timing device, the control module judges that the water inlet pipeline has no water leakage, the control module controls the valve module 300 to be completely opened so as to enable the water outlet flow of the water inlet pipeline to be recovered to be normal, and the timing device is reset; when the part of the pressure difference duration time exceeding the first preset time exceeds the second preset time of the timing device, the control module judges that the water inlet pipeline is likely to leak, the control module controls the valve module 300 to be completely closed, the communication between the water inlet pipeline and the water supply pipeline is cut off, and the timing device is reset. After the control module pre-determines that the water inlet pipe leaks and completely closes the valve module 300, the second pressure sensor 220 arranged behind the valve module 300 detects the pressure in the water inlet pipe within a period of time, and re-determines whether the water inlet pipe leaks according to the detection result of the second pressure sensor 220. If the second pressure sensor 220 detects that the pressure in the water inlet pipe keeps stable within the third preset time, the control module can judge that no water leakage occurs in the water inlet pipe, the control module can control the valve module 300 to be completely opened, and if the second pressure sensor 220 detects that the pressure in the water inlet pipe continuously drops within the third preset time, the control module can judge that water leakage occurs in the water inlet pipe and keep the valve module 300 closed. Except the water leakage detection and protection method, the water leakage protector can also perform high-pressure protection on the water inlet pipeline, specifically, a high-pressure protection value is set in the control module, the first pressure sensor 210 and the second pressure sensor 220 continuously detect the pressure inside the shell, and the control module collects the pressure values detected by the first pressure sensor 210 and the second pressure sensor 220 in real time. When the pressure in the water supply pipeline is increased, the pressure in the shell is also increased. When casing internal pressure is greater than the high pressure protection value, first pressure sensor 210 or second pressure sensor 220 detect when intake pipe internal pressure is greater than the high pressure protection value, and control module just can control valve module 300 and close, cuts off the intercommunication of intake pipe and water supply pipe, prevents that high-pressure liquid from entering into the intake pipe and rises bad intake pipe. After the valve module 300 is closed, the first pressure sensor 210 arranged at the front end of the valve module 300 continuously detects the internal pressure of the first pipeline 110, and when the pressure detected by the first pressure sensor 210 is smaller than a high-pressure protection value, the control module can control the valve module 300 to be opened, so as to recover the communication between the water inlet pipeline and the water supply pipeline. If the water leakage protector has detected that water leakage has occurred in the water inlet pipe and the valve module 300 is closed, the valve module 300 is not opened even if the first pressure sensor 210 detects that the internal pressure of the first pipe 110 is less than the high pressure protection value.

According to the utility model discloses protector that leaks through so setting up, can reach some effects as follows at least, the protector that leaks judges whether inlet channel takes place to leak according to the time that the pressure difference lasts in first pipeline 110 and second pipeline 120, can leak the detection to the pipeline under the prerequisite that does not influence user's water. When the user water consumption time exceeds the first preset time and does not exceed the second preset time, the valve module 300 can partially close the water outlet flow of the water inlet pipe to remind the user that the water leakage protector is about to pre-judge that the water inlet pipe leaks, at the moment, the user only needs to close the water outlet end of the water inlet pipe within the second preset time, the control module can judge that the water inlet pipe does not leak and completely open the valve module 300, and the water outlet flow of the water inlet pipe can be recovered to be normal. The control module group predetermines the inlet channel back that leaks according to pressure difference duration, can detect the pressure of inlet channel once more through second pressure sensor 220 to judge whether the inlet channel takes place to leak, whether the protector that leaks detects the inlet channel through two kinds of detection methods and takes place to leak, has effectively improved the accuracy that the protector that leaks and detect. First pressure sensor 210 continuously detects the pressure that the protector that leaks is close to water supply pipe one end, when the pressure that first pressure sensor 210 detected is higher than high pressure protection value, control module group just control valve module 300 closes, prevented effectively that high-pressure liquid from getting into the intake pipe and rising bad intake pipe, if the protector that leaks has detected to have taken place to leak in the intake pipe and has closed valve module 300, even first pressure sensor 210 detects first pipeline 110 internal pressure and is less than high pressure protection value, valve module 300 can not open yet.
