摘　　要：直流式太阳能热水系统的出口流量控制是保证系统正常运行的关键之一。介绍了定温变流量温控阀局部阻力系数的测定方法和试验研究结果。这种规格的温控阀可以用于小于 60 m2 的直流式太阳能热水系统中 。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.
