In China, the heating measurement system employed a ball valve to control the flow rate on the pipe inlet of the house. Unsurely, the valve remain turn on when the inhabitant at home and remain cut off when the inhabitant go to work, which can make a step change to water supply temperature. In this paper, the characteristic of the temperature distribution curve of radiator was analyzed in transient, the parallel moving presumption of the temperature distribution curve was proposed, according to the presumption, the functional relation between heat dissipating capacity of radiator and the time in transient was put forward, the rationality of the functional relation was proved by experiments.
