In this embodiment, before the valve leak detection is performed on the detection valve including the main valve, the auxiliary valve, and the branch valve, the following steps are further required: holding the sound listening rod, inserting the lower section of the sound listening rod into a tap water pit, rotating the sound listening rod to enable the transverse rod on the left side of the sound listening rod to hook the operating ring on the left side of the cover body from right to left and push the left operating ring to move leftwards, reversely rotating the sound listening rod to enable the transverse rod on the right side of the sound listening rod to hook the operating ring on the right side of the cover body from left to right and enable the sound listening rod to translate to the middle position of the two operating rings, and finally pulling the sound listening rod upwards. Because the two operation rings are positioned on the same side of the cover body, the pulling force applied by the listening rod to the cover body is positioned on one side of the cover body instead of the whole body, and the positioning block on the inner wall of the side cover body is most easily separated from the opening part of the guide cover by the pulling force in the direction. Once one positioning block is separated from the opening part of the guide cover, other positioning blocks are also separated from the opening part of the guide cover in a proper state, so that the effect of quickly uncovering is achieved. After the cover body is taken off from the guide cover, the lower section of the listening stick is separated from the two operation rings, and then the relevant operation of valve leakage detection is carried out.
In order to improve the detection accuracy, during the fact leak detection work, 1-4 early morning points are generally selected, and at the moment, residents basically fall asleep, water-consuming enterprises stably operate, and the water consumption is relatively constant. The leakage detection in the period can detect and judge the water pipe without water, namely the water pipe without water leakage, and then the directional detection can be carried out on the residual water pipe with little water or water leakage, so that the accuracy is greatly improved. In addition, in the actual leakage detection work, the error estimated value is determined according to the actual running environment and the condition of the tap water pipe, the error estimated value of the district paved water pipe is generally 0-1 ton/h within 5 years, the error estimated value of the district paved water pipe is 1-3 tons/h within 5-10 years, and the error estimated value of the district paved water pipe is within 5 tons/h over 10 years. In order to accurately master the accurate water consumption of a water-using enterprise or a user at night, the water consumption of the same time period can be calculated averagely in a week, so that the water consumption of the water-using enterprise or the user at night can be basically determined when the leakage detection work is performed. Subtracting the water consumption from the flow difference before and after closing the valve, if the water consumption is within the error estimated value, no water leakage exists, and if the water consumption exceeds the error estimated value, the water leakage condition exists, and the detection of the hearing leakage is needed. In this patent, the detection valve will send the instantaneous flow and pressure values to the server within a set time interval, such as 10 seconds or 1 minute, and the server will automatically record and draw a table to make a judgment on the leak point by the staff.
In this patent, the server, the detection valve and the stethoscope are ready-made products purchased in the market, the detection valve is equivalent to a combination of a flowmeter, a pressure gauge and a valve, and the structure and the working principle thereof belong to known technologies and are not described in detail herein.

fourth, the hearing leakage detection step: the stethoscope is held by a hand, a headset presses a conical block of the listening stick to the ground corresponding to the pavement track of the water leakage pipe, the larger the water leakage sound transmitted by the headset is, the closer the water leakage point is proved, and when the water leakage sound of the pressing position of the conical block reaches the maximum, the position is judged to be the water leakage point;
and fifthly, if the upper-level water pipe is watertight, arranging the first-level average flow value and each second-level average flow value into an average value row according to the acquisition time, wherein the difference between the adjacent front and rear values in the average value row represents the flow difference between the front and rear of the lower-level valve corresponding to the rear value, if the difference between the flow difference and the error estimated value is zero, the downstream user of the lower-level valve is proved to be in a water-free state and watertight, and if the difference between the flow difference and the error estimated value is not zero, the downstream water pipe of the lower-level valve is proved to be in a water-use state or the downstream water pipe of the lower-level valve is leaked, and a fourth step of hearing-leakage detection step is required.
6. The leakage detection method of the tap water supply device with the water leakage self-detection function as claimed in claim 5, wherein the method comprises the following steps: if a plurality of branch water supply pipes are arranged on the auxiliary water supply pipe, and a branch valve is arranged at the water inlet end of each branch water supply pipe, the auxiliary water supply pipe and the downstream branch water supply pipe form a detection unit, then the method further comprises a sixth step of determining the upper water pipe and the lower water pipe according to the first step, regarding any upper water pipe and all lower water pipes downstream of the upper water pipe as a detection unit, regarding a water supply structure formed by the upper water pipe and the lower water pipes as a water supply structure formed by the main water supply pipe and the auxiliary water supply pipe, and repeating the two to five steps, so that the water leakage condition and the water leakage position of which lower water pipe exist can be determined.
7. The leakage detection method of the tap water supply device with the water leakage self-detection function as claimed in claim 6, wherein the method comprises the following steps: and step seven, if a plurality of lower water pipes are arranged at the downstream of the lower water pipe, the lower water pipes are defined as an upper water pipe and a lower water pipe according to the upstream-downstream relation of water supply, and the water pipes are treated according to the sixth step.
8. The leakage detection method of tap water supply device with leakage self-detection function as claimed in any one of claims 5 to 7, characterized in that: in the third step, after the lower-stage valve is closed, valve leakage detection is needed, including a handheld stethoscope and a headset, the lower section of a listening stick is inserted into a detection tube along a guide cover, and a conical block at the lower end of the listening stick is correspondingly pressed and matched with a conical hole on the detection block, if water leakage occurs, the headset sends out water leakage sound, and the fact that the lower-stage valve is not closed and needs to be closed again is proved; and after the earphone is closed again, repeating the steps until the earphone cannot hear the water leakage sound.
9. The leakage detection method of the tap water supply device with the water leakage self-detection function as claimed in claim 8, wherein the method comprises the following steps: the last step is that after water supply is restored after detection, the cone block and the lower section of the listening rod are inserted into an operation hole at the upper end of the operation block, the elastic rib is in clamping fit with the lower section of the listening rod, then the listening rod is held by hand, the cover cap is detected into a tap water pit through the operation block, and the opening of the cover body is aligned and close to the guide cover; when the positioning block on the inner wall of the cover body is clamped to the opening of the guide cover, the listening rod is pulled vertically upwards, so that the listening rod and the cover cap can be separated, and the function of plugging the guide cover by the cover cap on the ground is completed.
