Water tank overflowing device

Abstract

Disclosed is a water tank overflowing device. When the water level of a water tank is normal, gravity blocks act under earth gravity, a sealing flap is controlled by the gravity of the gravity blocks to rotate downwards to ensure that the overflowing device is in a closed state and insects are prevented from entering the water tank from the overflowing device to pollute water, when the water level of the water tank is higher than the designed water level and the water needs draining from the overflowing device, the water enters the overflowing device, and when the gravity of the water is larger than that of the gravity blocks, the sealing flap is pushed by waterpower to rotate and the overflowing device is opened to achieve the purpose to drain the water.

Description

technical field [0001] The invention relates to a water tank overflow device, in particular to a gravity type water tank overflow device. Background technique [0002] In the existing technology, in order to prevent the failure of the water inlet valve, the reserve water level of the water tank will exceed the design height and cause the water tank to be overloaded and damaged or burst. Generally, an overflow pipe is installed to drain water to ensure that the reserve water level of the water tank does not exceed the set water level. , The structure of the overflow pipe is a hollow pipe, which is in a state of direct communication with the outside world. Animals such as insects can easily enter the water tank through the overflow pipe, causing the water quality in the water tank to be polluted and affecting people's health. Contents of the invention [0003] The purpose of the present invention is to design a water tank overflow device, which is usually in a closed state ...
