[0022] refer to Figure 1-3As shown, a one-way water stop valve comprises a connecting shell 1, a hardware cylinder 2 is arranged in the connecting shell 1, a valve body 3 is arranged on the top of the connecting shell 1, the bottom surface of the valve body 3 is in contact with the top surface of the connecting shell 1, a first water flow channel 4 and a second water flow channel 5 are arranged on the valve body 3, the valve body is a cavity, a first interface end 6 and a second interface end 7 communicating with the cavity are arranged in the valve body 3, the first interface end 6 is communicated with the first water flow channel 4, the second interface end 7 is communicated with the second water flow channel 5, the hardware cylinder 2 is connected with a conductor 8, a coil is arranged in the hardware cylinder 2, the coil is connected with the conductor 8, a support cylinder 9 is arranged in the hardware cylinder 2, A fixing seat 10 and a movable iron core 11 are provided in the support tube 9. There is a gap between the movable iron core 11 and the support tube 9. A spring 12 is installed on the fixing seat 10. The spring 12 is connected to the movable iron core 11 in a sleeve. The spring 12 pushes the movable iron core 11 upward. The upper end of the movable iron core 11 passes through the top of the connection shell 1 and is equipped with a seal 13. The seal 13 is located in the cavity of the valve body 3. When the spring 12 pushes the movable iron core 11 upward, the seal 13 blocks the first interface end 6 and the second interface end 7. After the conductor 8 is energized, the movable iron core 11 moves downward to drive the seal 13 to disengage from the first interface end 6 and the second interface end 7. The connection shell 1 is used for assembly connection with other components. A plurality of screw holes can be set on the connection shell to be locked and installed with other components by bolts. The fixing seat is a fixed iron core. After passing electricity, electromagnetic force will be generated to pull the movable iron core.

[0023] When the conductor 8 is not energized, the movable iron core 11 is not subjected to electromagnetic force and is supported upward by the spring 12. The selection of the spring force needs to ensure that: when the movable iron core 11 is not subjected to electromagnetic force, the spring 12 pushes the movable iron core 11 upward, so that the movable iron core 11 pushes the seal 13 upward, and the seal 13 seals the first interface end 6 and the second interface end 7. When the conductor is energized, the movable iron core 11 is subjected to electromagnetic force and moves downward, driving the seal to move downward, so that the first interface end and the second interface end are no longer sealed.

[0024] The first interface end 6 is arranged at the central area of ​​the valve body 3, the second interface end 7 is arranged at one side of the valve body 3, and the first water flow channel 4 and the second water flow channel 5 are respectively arranged at both sides of the valve body 3. The first interface end is extended for a certain distance, and the first interface end and the second interface end are connected to each other through the cavity of the valve body to realize water inlet and outlet.

[0025] The seal 13 includes a lower seal seat 131 and an upper seal seat 132. The upper seal seat 132 is arranged on the lower seal seat 131. The outer side surface of the lower seal seat 132 contacts the inner side surface of the cavity of the valve body 3 to form a seal. The upper seal seat 132 is used to seal the first interface end 4, and the lower seal seat 132 is used to seal the second interface end 5. The lower seal seat 132 and the cavity of the valve body 3 form a piston-like structure. A connecting rod is provided at the upper end of the movable iron core 11. A through hole 14 is provided at the top of the connecting shell 1. The connecting rod passes through the through hole 14 and is connected to the seal 13. The lower seal seat 131 accommodates the through hole. When the seal 13 is driven to move down to the top surface of the connecting shell 1, the through hole is located in the lower seal seat 131, that is, the lower seal seat 131 seals the periphery of the through hole, and the water in the cavity of the valve body will not flow downward.

[0026] The support tube 9 is provided with a support plate 15 on the upper part, and the support plate 15 is locked and connected with the top of the connection shell 1. The support tube 9 is provided with a bottom plate 16 on the lower part, and the bottom plate 16 is locked and connected with the bottom surface of the connection shell 1. There is a gap between the support tube 9 and the hardware tube 2. The support tube is located in the hardware tube, and the upper end of the hardware tube abuts against the support plate, and the lower end of the hardware tube abuts against the bottom plate.

[0027] The utility model realizes opening and closing through electromagnetic control. The first water flow channel and the second water flow channel can be switched flexibly.

[0028] When the power is not on, the spring 12 pushes the movable iron core 11 upward, and the movable iron core 11 drives the seal 13 to move upward, wherein the upper sealing seat 132 presses against and seals the first interface end 6, and the lower sealing seat 132 seals the second interface end 7 from the side, and is in a closed state at this time. Water enters the valve body 3 from the first water flow channel 4, and at this time, because the first interface end 4 is sealed, water cannot enter the cavity of the valve body 3.

[0029] The conductor is energized, so that the movable iron core 11 is pulled downward by the electromagnetic force, the movable iron core 11 moves downward, and the spring 12 is compressed at the same time. The movable iron core 11 drives the seal 13 to move downward, so that the first interface end 4 and the second interface end 5 are no longer sealed, until the seal 13 moves to the top surface of the connecting shell 1, and the water entering from the first water flow channel 4 enters the cavity in the valve body 3 through the first interface 6 end, and then enters the second water flow channel 5 from the second interface end 7 and flows out.

[0030] When it is necessary to close again, it is only necessary to cut off the power supply. At this time, the spring itself is subjected to the rebound force and drives the movable iron core to move up again, driving the sealing member to seal the first interface end and the second interface end again, and entering the closed state.

[0031] Water can also flow in from the second water flow channel and then flow out from the first water flow channel.

[0032] It should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
