增加出水管阻力以减低流量，检查泵吸水管内阻力，检查底阀减小吸水高度。

Add the resistance in the outlet to lower the capacity. Check the resistance in the suction pipe of pump. Check the bottom valve and lower the high of suction position.

底加热时，热管内的运动多是循环的单向脉冲流动，并不是工质在某一个U型管或直管内的往复随机振荡。

In bottom heat mode, most of the movement of working fluid is pulsating and one-direction circulating flow, not random reciprocal oscillating in certain straight pipe or U-shaped pipe.

底阀是一种节约能源的阀，一般安装在水泵水下吸管的底端。限制水泵管内液体返回水源，起着只进不出的功能。

Bottom valve is a energy saving valve, usually installed in the straw at the bottom of the underwater pump. Limit the liquid return pipe water pump, plays not only into the function.
