Abstract
The utility model discloses an automatic recovery system for water drained by a heater for a heating network. The automatic recovery system comprises a pressure-free water tank, wherein a floating ball is arranged in the pressure-free water tank, a water pump starting switch is arranged at the high end of the inner wall face of the pressure-free water tank, a water pump stopping switch is arranged at the low end of the inner wall face of the pressure-free water tank, and a cross bar which is horizontally arranged and corresponds to the water pump starting switch and the water pump stopping switch is fixed to the floating ball. A water inlet of the pressure-free water tank is connected with a water outlet of the heater for the heating network through a pipeline. A water outlet of the pressure-free water tank is connected with a drain pump through a pipeline. The drain pump is connected with a deaerator through a pipeline. The automatic recovery system for the water drained by the heater for the heating network is reasonable and ingenious in structural design; the drain pump is automatically controlled to drain the water after the water drained by the heater for the heating network is accumulated into a certain amount, as a result, long-term vibration of a drain pipeline cannot be caused, the drained water is safely recovered, and equipment is protected; moreover, automatic operation is completely realized, and the automatic recovery system is high in efficiency and saves energy.
