A nipple drinker is available for drinking water from 10 to 15 pigs. It is composed of a valve stem, a steel ball, a drinking fountain body and the like.
When the pig is drinking water, the valve stem is arched upward, and the two sealing rings formed by the valve stem and the steel ball are lifted, so that the water flows out through the staggered gap. When the pig leaves, the steel ball and the valve stem automatically return to stop the water supply.
When using the nipple drinker, the main pressure should not exceed 19.6 kPa, otherwise the water will form a water spray when it passes through the drinker, which is unfavorable for pigs drinking water.
