A SOLAR HEATER, A SOLAR COLLECTOR AND A SAVING MATERIAL METHOD OF CONTROLLING A PRESSURE-DRAINAGE BAG POSITION

摘要

A solar heater, a solar collector (A) and a saving material method of controlling a pressure-drainage bag position are disclosed. The solar collector (A) is installed on a bracket (D) or a sun tracking system (B), a water outlet (A7) of the collector (A) is communicated with a water tank (C), a water outlet (C4) of the water tank (C) is communicated with a water knockout drum (A6) through an electrical controlling valve (1) and a servo water pump (2) controlled by a thermostatic starter (3), a device (5) for controlling liquid level is located in the pressure-drainage means.
