As shown in fig. 1-5, a high-efficiency sealing water stop valve includes a housing 10, a water inlet 20, a water outlet 30, and two sets of sealing devices, wherein the first set of sealing device is used for sealing the water inlet 20, the second set of sealing device is used for sealing the water outlet 30, and the first set of sealing device and the second set of sealing device are controlled to be opened and closed by a central control.

Preferably, the water inlet 20 and the water outlet 30 are provided with connecting pipes, the connecting pipes are used for connecting the water stop valve with a pipeline, and a PVC pipe or a plastic hose can be used.

Preferably, the first sealing device includes a fixed plate 51 and a movable plate 52, the fixed plate 51 is fixedly connected to a portion above the channel in the channel of the housing 10, a chute 11 is disposed in the channel along a cross section of the channel, the movable plate 52 is clamped in the chute 11, the movable plate 52 is located on a side of the fixed plate 51 away from the water inlet 20 and abuts against the fixed plate 51, and the movable plate 52 slides along the chute 11 and can cooperate with the fixed plate 51 to block the entire channel.

Preferably, the second set of sealing means comprises a plug body 61 and a plug hole 62, the plug body 61 being used for plugging the plug hole 62.

Preferably, the plug body 61 is a cone, and the plug hole 62 is matched with the plug body 61 in shape and size.

Preferably, the plug body 61 is made of rubber.
