Briefly, if the lower part of the water supply pipe is fixed by a certain level, the water is only true as much as the lower end and the water supply is automatically stopped. Then, as the livestock feeds the water inside the tank, the water level drops and the water remaining inside the water pipe flows into the water tank, so that air flows into the water through the lower end of the water pipe to release the negative pressure of the water level control device. The valve is open again.

By the way, there is a significant problem in determining the water level to the lower end of the water supply pipe. In other words, raising the water level at the bottom of the water pipe to raise the water level can make it easier for livestock to eat water in the tank, but since it is always full of water, it is easily polluted and cannot be drinking fresh water. It is easily deteriorated and brings a lot of losses. When water and feed are mixed, they deteriorate in a short time, causing severe odors, causing livestock stagnation or disease, such as animals refusing to eat or being left for a long time. In the case of pigs, the feed and water are intensively ingested at a specific time. In the hot weather in the middle of the day or summer, the feed and water are not eaten and the water is so bad that it is easily deteriorated and polluted in a short time.

Conversely, if the water level is lowered, that is, if the water level is too low, the water level will not be maintained and the water will continue to flow, which may cause malfunctions. do.
