More Information
Summary:The utility model relates to a controller for filling and draining water, which is used for a solar energy water-heating system and mainly composed of a controller casing, a valve core, a one-way valve, a transposition ring, etc. The valve core reaches different service positions according to requirements of a system through the indexing coordination of the valve core generated from water pressure and the sole weight of the valve core relative to the transposition ring to realize functions of water filling of the water tank of the system, emptying of the water filling pipe, and use of hot water in the water tank. The utility model has the advantage of advanced design and solves technical problems existing in solar water heaters for a long term. The controller for filling and draining water is an important breakthrough in the technical field.
