新型恒液位箱是一种设计新颖的液体恒位控制设备,主要由密闭贮液箱和无浮球阀恒位箱构成。其原理是在密闭贮液箱变液位情况下,通过空气一液体的自动置换,始终保持无浮球阀恒位箱液面波动在0～1cm 之间,为间歇或连续等量输液提供稳定液位。文中还介绍了实际应用中需注意的几个问题。 The new constant liquid level box is a novel design of liquid constant position control equipment, mainly by the sealed liquid tank and no float valve constant position box. The principle is to change the level of liquid in the closed tank, through the automatic replacement of air-liquid, and always maintain a float-free valve constant tank liquid level fluctuations between 0 ~ 1cm, intermittent or continuous infusion of the same amount to provide a stable solution Bit. The article also introduces several problems to be noticed in practical application.
