[0019] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0020] like Figure 1 and 2 As shown, the utility model comprises a solenoid valve 1 and a water leakage detection valve 2.
[0021] The water inlet of the solenoid valve 1 is connected to the household tap water main valve through a water pipe, and the water outlet of the solenoid valve 1 is connected to the water inlet of the water leakage detection valve 2 through a water pipe.

The large diameter water hole of the main valve body 22 is slidably matched with the water blocking ring 25, and the outer end wall of the water blocking ring 25 is tightly attached to the inner wall of the large diameter water hole and sealed therewith.
[0023] The water blocking ring 25 has a conical through hole at its center, in which a plunger 24 is installed, and the shape of the lower end of the plunger 24 corresponds to the conical through hole, blocking the conical through hole of the water blocking ring 25. The upper end of the plunger 24 is fixedly connected to the inner wall of the large-diameter water hole through a connecting frame, and a connecting hole is provided on the connecting frame.
[0024] The lower end wall of the main valve body 22 is provided with a plurality of stepped guide holes evenly arranged in a circular shape, the stepped guide holes are connected to the large diameter water holes, the upper end of the stepped guide holes is a small diameter guide hole, and the lower end is a large diameter guide hole, the upper end of the guide rod 26 passes through the small diameter guide hole and is fixedly connected to the water blocking ring 25, and the lower end of the guide rod 26 is provided with a flange, which slides up and down with the large diameter guide hole.
[0025] In the optimized solution, a sealing ring is installed between the small diameter guide hole of the stepped guide hole and the guide rod 26 .
[0026] The lower end of the main valve body 22 is provided with a pressure regulating mechanism 23, which includes a regulating rod 232, a connecting ring 233, an adjusting sleeve 234 and an adjusting spring 231. The upper end of the regulating rod 232 is inserted into the large-diameter guide hole, the flange of the guide rod 26 is connected to the upper end of the regulating rod 232 through the adjusting spring 231, and the lower ends of the plurality of regulating rods 232 are connected through the connecting ring 233. The outer wall of the lower part of the main valve body 22 is provided with an external thread, and the inner wall of the regulating sleeve 234 is provided with an internal thread. The regulating sleeve 234 is threadedly matched with the main valve body 22, and the lower end wall of the regulating sleeve 234 is pressed against the lower end of the connecting ring 233. By rotating the regulating sleeve 234, the regulating sleeve 234 can drive the guide rod 26 to move up and down through the connecting ring 233, thereby adjusting the compression amount of the adjusting spring 231 and controlling the pressure required for the water blocking ring to be pressed down.
[0027] In the optimized solution, the upper and lower ends of the main valve body 22 are respectively fixedly installed with connecting pipes 21, the connecting pipe 21 is connected to the small diameter water hole, and the lower end of the adjusting sleeve 234 is installed with a guide cylinder 235, and the guide cylinder 235 is provided with a guide through hole.

The circuit is a prior art, and its specific structure is not repeated. When the upper conductive contact 28 contacts the lower conductive contact 29, the solenoid valve 1 starts to close.
[0029] The operation process is as follows: when you need to go out, close the main control switch. When the tap water leaks, the tap water enters the water leakage detection valve 2 through the solenoid valve 1 and the water pipe. At this time, the water pressure on both sides of the water leakage detection valve 2 produces a pressure difference. The tap water presses the water blocking ring downward, so that a gap is generated between the water blocking ring and the plunger 24, and the tap water flows out from the gap. During the movement of the water blocking ring, the guide rod 26 compresses the adjustment spring 231. When the upper conductive contact 28 and the lower conductive contact 29 are connected, the entire circuit of the control solenoid valve 1 is connected, and the solenoid valve 1 is closed, thereby preventing the tap water from leaking. When using water normally, turn off the main control switch. When the upper conductive contact 28 and the lower conductive contact 29 are connected, the entire circuit will not be energized, and the solenoid valve 1 will not work.
[0030] It should be noted that the specific embodiments of the present invention have been described in detail. For those skilled in the art, various obvious changes to the present invention without departing from the spirit and scope of the present invention are within the protection scope of the present invention.
