Water cold accumulation tank 's encapsulation system

The utility model discloses a water cold accumulation tank's encapsulation system, the encapsulation system is located more than the water cold accumulation tank normal water bit line, the encapsulation system includes vault and lateral wall, be provided with on the vault and annotate the nitrogen mouth, be provided with the gas vent on the lateral wall, still be provided with in the encapsulationsystem can communicate the atmosphere with the inside spill pipe of encapsulation system, pour into sealed water in the spill pipe into. Owing to install the spill pipe in the encapsulation system. Under the normal condition, sealed water level in the lowest order of spill pipe for sealed nitrogen gas. When the atmospheric pressure of internal of jar reduced by a wide margin, it is internal thatthe atmospheric pressure will seal water pressure income jar, and the air is personally experienced sth. Part of the body from spill pipe entering jar for the interior external pressure of the surge drum body prevents that jar
