Water supply in modern pig farms is usually pressured. Its water supply system mainly includes water supply pipelines, filters, pressure reducing valves, automatic drinking fountains, etc.
There are many types of automatic drinking fountains for pigs, including duckbill type, nipple type, cup type, etc. (pictured). The most commonly used are duckbill type automatic waterers.

The duck-bill type pig automatic waterer is mainly composed of a valve body, a valve core, a seal ring, a return spring, a plug cover and a strainer. The valve body and valve core are made of brass and stainless steel. The spring and filter are made of stainless steel. The plug cover is made of engineering plastic. The overall structure is simple, corrosion-resistant, reliable, non-leakage, long life. Drinker, bite and press down the valve stem, water flows out from the gap between the valve core and the seal ring, and enters the pig's oral cavity. After the pig's mouth is released, the spring is reset by the return spring tension, the valve stem is closed, the water outlet gap is closed, and the water stops flowing out. The duckbill drinking fountain has good sealing performance, the pressure decreases when the water flows out, and the flow velocity is low, which meets the requirements of pigs for drinking water.
Duckbill pig drinking fountains, generally have two sizes, small size, flow rate of 2 to 3 liters / minute), large (flow rate of 3 to 4 liters / minute), small pigs and nursery pigs, medium pig And big pigs use large ones. There are two types of angles to install this waterer: horizontal and 45-degree angles. The height above ground varies with pig weight.
