And in winter, entering water temp is lower, and in certain temperature range, spring 13 elasticity coefficient are a stable smaller value.Spring 13 meetings that elasticity coefficient is little are stabilized in a suitable position so that move on the spool 12, thereby so that the aperture of the opening 19 between spool 12 and the shell 16 is less, therefore, obtain a less flow value.Select the spring 13 of suitable memory parameter, can guarantee that elasticity coefficient is constant in certain temperature range, thereby so that flow value immobilizes, also namely in a wider temperature range, obtain a fixing flow, realized the current limliting of flow regulator 1 and regulating of cut-off current.
If flow regulator 1 is applied in the gas water-heater, so, in winter, can obtain less cut-off current, in summer, will obtain larger cut-off current.Can select the spring 13 of suitable memory parameter according to different water heater loads, thereby the cut-off current that guarantees the current in winter can allow water-exit temperature reach the bathing temperature that the user needs, and the water-exit temperature in summer is unlikely to too high, improves user's bath comfort degree.
