| Abstract: | One of the key points to ensure the normal operation of "once-through solar water heating system" is the outlet flow quantity control. The testing method was introduced with the result of the experiment for the partial resistant coefficient of the control valve under fixed temperature and varied flow quantity. This kind of control valve could be used in once-through solar water heating systems with a collection area of less than 60 m+2 , so as to adjust the outlet flow quantity of the system. |
