Detailed Description

Embodiments of the present utility model are described in further detail below with reference to the accompanying drawings and examples. The following examples are illustrative of the utility model but are not intended to limit the scope of the utility model.

As shown in fig. 1-4, the utility model provides a water conservancy check valve, which comprises a valve body 1, wherein a partition board 2 is arranged in the valve body 1, the partition board 2 divides the interior of the valve body 1 into a water inlet chamber 3 and a water outlet chamber 4, a water passing hole 5 is formed in the center of the partition board 2, a valve cover 6 is arranged at the top of the valve body 1, a fixed rod 7 is arranged at the bottom of the valve cover 6, the fixed rod 7 penetrates into the water outlet chamber 4, a movable sleeve 8 is sleeved on the surface of the fixed rod 7, the bottom end of the movable sleeve 8 is connected with a valve clack 9, two brackets 10 are symmetrically arranged on the surface of the valve clack 9, first magnets 11 are fixedly connected to the bottom sides of the brackets 10, and two second magnets 12 are symmetrically arranged at the periphery of the water passing hole 5 at the top of the partition board 2.
