The CAM member operably connects a temperature control knob to the thermostat.
凸轮元件把一个温度控制旋钮可操作地连接于恒温器。
Thus, frequent adjustment of the control knob is required to maintain constant delivery pressure.
因此经常要调整控制钮，以维持恒定的输出压力。
By adjusting the control knob, the second stage reduces the intermediate pressure to the desired delivery pressure.
通过调整控制钮，第二级把中间压力降到需要的输出压力。
When the temperature control knob to set a temperature, hot and cold water mixing valve through proportional control into the outlet, the outlet temperature is always constant.
当温度调节旋钮设定某一温度后，混水阀通过调节进入出水口的冷热水比例，使出水温度始终保持恒定。
When the temperature control knob to set a temperature, hot and cold water mixing valve through proportional control into the outlet, the outlet temperature is always constant.
当温度调节旋钮设定某一温度后，混水阀通过调节进入出水口的冷热水比例，使出水温度始终保持恒定。
