一、自动化控制装置的构造:控制装置的主要组成部分是用玻璃吹制而成,其形状如图1。玻璃管内有四个狭窄部分(用来堵住空气)及四个三瓣部分(用来使空气通过,同时防止玻璃球跑掉),在每个狭窄部分和三瓣部分之间,均放置梭形玻璃球一个,编号为第1、2、3、4球。玻璃管上端中央下面有一排气孔。二、应用原理(图2):当A瓶高于B瓶时,A瓶的水借重力经皮管D流至B瓶,而A瓶中产生负压,C瓶之空气经过G管和F管
First, the automatic control device structure: The main component of the control device is blown glass, the shape shown in Figure 1. The glass tube has four narrow sections (to block the air) and four three-section sections (to allow air to pass through while preventing the glass balls from running away). Place the shuttle between each narrow section and the three sections A shaped glass ball, numbered 1, 2, 3, 4 ball. There is a vent below the center of the glass tube. Second, the application of principles (Figure 2): When the A bottle is higher than the B bottle, A bottle of water by gravity through the D tube to the B bottle, and A bottle of negative pressure, C bottle of air through the G tube and F tube
