Product Function Introduction This is not a water spray, it is to prevent water from flowing back. The water will only flow out when it is closed. The vacuum breaker is used to automatically eliminate the vacuum in the water supply pipeline, effectively prevent siphon backflow and eliminate siphon pollution. The vacuum breaker is a device that can automatically vacuum the water supply pipeline. It can effectively prevent siphon backflow and avoid backflow contamination of the water supply pipeline. When the water supply pressure drops, the vacuum breaker automatically opens and introduces atmospheric pressure into the water supply pipe, eliminating the vacuum in it. When the water supply returns to normal, the vacuum breaker will automatically close to maintain normal pressure in the water supply pipeline. Vacuum breakers are widely used in buildings, industrial water, urban water supply and other fields, playing an important role in ensuring water supply safety and preventing pollution.
