Abstract
The utility model relates to an automatic exhaust valve with variable submerged weight and double air passages, which is used for fast and automatically feeding and discharging air for a pipeline system. A big air drain and a small air drain of the utility model are composed of a floating ball with a big air valve and a small air valve. The valve is not provided with mechanical driving mechanisms, such as hinges, levers or connecting rods, etc., and vulnerable metal pieces, such as latches, bolts or springs. A floater with variable buoyance and weight is adopted to improve the capacity of resisting high working pressure and the air displacement. The heavy and large floating ball is not needed and the requirement to the material and the hardness of the floating ball is not high; because the valve can not collapse under any high pressure, the valve is not very big. Meanwhile, the air drain can be repaired by water with voltage once the air drain is blocked. When the automatic exhaust valve with variable submerged weight and double gas passages is arranged on the position (the outlet of a water pump or the position near a valve) where the water hammer always occurs, the air can be fed in and discharged out in a large scale, and the negative pressure can be balanced fast so as to relieve the damage caused by the water hammer.
