According to the utility model discloses the method that adopts the protection filter that leaks to detect leaks of second aspect embodiment, including following step: detecting the liquid pressure at two sides of a filter element in the water leakage protection filter; and when the time that the pressure difference exists continuously in the liquid on the two sides of the filter element exceeds a first preset time, judging that water leakage occurs in the water pipeline for the user.
By adopting the method for detecting water leakage by adopting the water leakage protection filter, the water leakage protection filter can judge whether the water pipeline of a user leaks water or not according to the time that the pressure difference between two sides of the filter element continuously occurs. Specifically, the first pressure sensor 300 is disposed between the filter element and the water inlet 110, and the second pressure sensor 400 is disposed between the filter element and the water outlet 120. When no water is used by a user or no water leakage occurs in a water pipeline of the user, the liquid in the water leakage protection filter is static, the pressure at each position in the valve body 100 is equal, and the numerical values detected by the first pressure sensor 300 and the second pressure sensor 400 are equal; when a user leaks water with water or a water pipeline of the user, the liquid may continuously pass through the water leakage protection filter, and since the pressure of the liquid may be reduced when the liquid passes through the filter element, that is, a pressure difference may occur between both sides of the filter element, the pressure detected by the first pressure sensor 300 may be different from the pressure detected by the second pressure sensor 400. 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 pipeline for the user leaks water, further control a valve in a water inlet pipeline in the water pipeline for the user 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 pipeline for the user does not leak, the water outlet end of the water pipeline for the user is closed, and the timing device is reset when the pressure difference on the two sides of the filtering element disappears. 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 user at the water use in-process control module group mistake and use the water pipeline to leak, and then cut off the intercommunication influence user's normal water of inlet channel and water supply pipe, for example, first preset time among the timing device is 5 minutes, if the user once water use time needs to exceed 5 minutes, alright with first preset time extension through control module group.
In some embodiments of the present invention, after the water pipe for the user is determined to leak, the valve in the water inlet pipe in the water pipe for the user is controlled to be closed. Through setting up as above, the control module group judges with the water pipeline of user after taking place to leak, just can control with the valve in the inlet channel in the water pipeline of user and close, cuts off the connection between inlet channel and the water supply pipe, reduces the harm that the water pipeline of user leaked and brought. When the protection filter setting that leaks between inlet channel and water supply pipe, and control module group judge that the user takes place to leak with the water pipeline, control module group just can control first valve module and close, cuts off being connected between inlet channel and the water supply pipe.
The utility model discloses a some embodiments, judge that the user takes place to leak with the water pipeline after, alarm device sends out the police dispatch newspaper to the user. Through the arrangement, the control module can control the alarm device to give an alarm to the user after judging that the water pipeline of the user leaks, so as to remind the user that the water pipeline of the user leaks. The alarm device may be an audible and visual alarm device or a buzzer, but is not limited to either.
In some embodiments of the present invention, the valve in the water inlet pipe in the water pipe for the control user is closed, specifically, the valve in the water inlet pipe in the water pipe for the control user is partially closed, when the time when the pressure difference still continuously exists between the two sides of the filter element exceeds the second preset time, the valve in the water inlet pipe in the water pipe for the control user is completely closed, otherwise, the valve in the water inlet pipe in the water pipe for the control user is completely opened.
Through the detection method, the water leakage protection filter can remind a user when the water consumption of the user exceeds the first preset time. Specifically, the timing device is also provided with a second preset time besides the first preset time, when the water using time of the user exceeds the first preset time in the timing device, the control module can control the valve part in the water inlet pipeline in the water using pipeline of the user to be closed, and the timing device continues to time the pressure difference duration. After the user closes the valve in the water inlet pipeline in the water pipeline, the user can obviously feel that the water outlet flow is reduced. At the moment, the user only needs to temporarily close the water outlet end of the water pipeline for the user within a second preset time, so that the liquid in the water leakage protection filter stops flowing, the pressure difference between the first pressure sensor 300 and the second pressure sensor 400 disappears, the control module can judge that no water leakage occurs in the water pipeline for the user, and further completely open and start the valve in the water inlet pipeline in the water pipeline for the user, the water outlet flow of the water pipeline for the user can be recovered to a normal value, and meanwhile, the timing device is reset; if the user has taken place to leak with the water pipeline, when the time that the pressure differential lasts exceeded first preset time and second preset time, the control module group just can control the valve in the inlet channel in the user's water pipeline and close completely, cuts off the intercommunication of inlet channel and water supply pipe, and the timing device zero clearing. Compared with the water leakage protection filter 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 using pipeline of the user leaks water and further closing the valve in the water inlet pipeline of the water using pipeline of the user to influence the normal water use of the user only by temporarily closing the water outlet end of the water using pipeline of the user 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 method for detecting water leakage by using the water leakage protection filter further comprises the following steps: and after a valve in the water inlet pipeline of the user water pipeline is closed, detecting the pressure change of the water leakage protection filter within a third preset time, if the pressure continuously drops and/or the pressure drops to exceed a preset value, keeping the valve in the water inlet pipeline of the user water pipeline closed, otherwise, controlling the valve in the water inlet pipeline of the user water pipeline to be opened.
Through the detection method, the first pressure sensor 300 and/or the second pressure sensor 400 can perform pressure detection on the water pipeline for the user again after the valve is closed so as to judge whether water leakage occurs, and the detection accuracy is further improved. Specifically, the water leakage protection filter is disposed behind a valve in a water inlet pipe of the user water pipe, and the control module determines that the user water pipe leaks water and controls the valve in the water inlet pipe of the user water pipe to be closed, and then controls the first pressure sensor 300 and the second pressure sensor 400 to detect the pressure in the valve body 100 for a period of time, and determines again whether the user water pipe leaks water according to the detection result. If the first pressure sensor 300 and the second pressure sensor 400 detect that the pressure in the water pipeline for the user is kept stable within the third preset time, the control module can judge that no water leakage occurs in the water pipeline for the user actually, and the control module can control the valve in the water inlet pipeline in the water pipeline for the user to be opened; if the first pressure sensor 300 and the second pressure sensor 400 detect that the pressure in the water pipeline of the user continuously drops or the change of the pressure exceeds a preset value within a third preset time, the control module judges that water leakage occurs in the water pipeline of the user and keeps the valve closed. According to the method for detecting water leakage by adopting the water leakage protection filter, whether water leakage occurs in the water pipeline of a user is judged in advance by detecting whether the pressure difference between the two pressure sensors exists or not and the duration time of the pressure difference, then the valve is closed when water leakage occurs, whether water leakage occurs in the water pipeline of the user is judged by detecting the pressure in the water pipeline of the user within a period of time through the first pressure sensor 300 and the second pressure sensor 400, and the accuracy of water leakage detection of the water leakage protection filter is effectively improved through double detection.
According to the utility model discloses third aspect embodiment's protection filter blowdown method leaks, including following step: when the liquid pressure difference between the two sides of the filter element is larger than the preset pressure value, the drain outlet 130 in the water leakage protection filter is controlled to be opened to drain the water leakage protection filter.
By the method for draining sewage of the water leakage protection filter, the water leakage protection filter can open the drain outlet 130 to drain sewage when excessive impurities are accumulated on the filter element.

According to the utility model discloses the protection filter that leaks through so setting, can reach following some technological effects at least, the protection filter that leaks can also play the effect whether the detection pipeline takes place to leak when playing the filtering action to liquid. Specifically, a filter element is arranged inside the valve body 100, a first pressure sensor 300 and a second pressure sensor 400 are respectively arranged on two sides of the filter element, the first pressure sensor 300 and the second pressure sensor 400 continuously detect the liquid pressure on two sides of the filter element, and when liquid passes through the filter element, the liquid pressure is reduced, that is, when liquid flows in the valve body 100, the pressure values on two sides of the filter element are unequal. When the liquid pressures detected by the first pressure sensor 300 and the second pressure sensor 400 are different, the control module controls the timing device to start timing, and when the duration time of the pressure difference exceeds the first preset time of the timing device, the control module can judge that water leakage occurs in a water pipeline for a user; when the duration time of the pressure difference value does not exceed the first preset time of the timing device, the control module can judge that the water pipeline for the user does not leak, the water outlet end of the water pipeline for the user is closed, and the timing device is reset when the pressure difference on the two sides of the filtering element disappears. The first preset time is generally longer than the maximum water taking time of a user, when the user uses water normally, the user only needs to close the water outlet end of the water pipeline of the user within the first preset time, the liquid stops flowing, the pressure difference value disappears, and the water leakage protection filter cannot misjudge that the water pipeline of the user leaks water. When the control module judges that the water pipeline of the user leaks water, the control module controls the valve of the water inlet pipeline in the water pipeline of the user to be closed, sends out the information of water leakage to the mobile equipment of the user through the communication device, and sends out an alarm to the user through the sound-light alarm device. The first pressure sensor 300 and the second pressure sensor 400 continuously detect the pressure at the two ends of the filter element, and when the pressure difference between the first pressure sensor 300 and the second pressure sensor 400 is greater than a preset pressure value, the control module controls the second valve module to open so as to open the sewage outlet 130 to discharge the impurities accumulated in the second accommodating cavity. Compared with the traditional water leakage protection filter with the water leakage detection function, the water leakage protection filter in the embodiment has simpler structure and lower manufacturing cost, and can control the water leakage protection filter to automatically discharge sewage according to the detected pressure difference.
