过去在压水试验中,为了保持水平必须固定一人,同时还得小心的控制着凡尔,一不小心,水桶内的水就会溢出或下降,很难达到理想的水平。为解决这一问题,我们制造了一种简单的自动保持水平仪,经过几个工地在压水试验中试用,效果良好,简介如下。一、仪器的原理及结构利用天平杠杆原理,以浮托的力量来自动控制流 In the past, in the water pressure test, one person had to be fixed to maintain the level, and at the same time, it was necessary to carefully control the valve. If it was not careful, the water in the bucket would overflow or fall, and it would be difficult to achieve the desired level. In order to solve this problem, we have created a simple automatic hold level meter that has been tried out in several water pressure tests in several construction sites. The results are good. The introduction is as follows. First, the principle and structure of the instrument leveraging balance lever principle, automatic control of flow with the power of floatation
