Abstract
Description
Technical field:
[0001] The invention relates to an automatic closing device for liquid water supply, in particular to a gravity type automatic closing device for liquid quantitative water supply. Background technique:
[0002] Most of the existing automatic shut-off devices for liquid water supply need to use components such as power supply, water level gauge and electromagnetic valve to complete the closing action when the water is full. The principle is that the liquid flows into the container through the designed flow channel through the electromagnetic valve in the flow channel. When the water level reaches the original design height, the water level gauge touches the liquid and floats up, cut off the power supply and close the electromagnetic valve in the water inlet flow channel, and the water inlet is closed synchronously. All water and electricity off actions.
[0003] The mechanical water shut-off device that does not use electric energy mostly uses a float switch...
