TKWL-140系列玻璃板液位计

TKWL-140 GlassPlate Liquid Level Meter

概述

  TKWL-140系列玻璃板液位计主要用于各种受压容器或敞口容器（如塔、罐、槽等）内的液体液位 现场直接指示。

Overview

  TKWL-140 glass plate liquid level meter is mainlyused in direct site indication of the liquid level inside various pressurevessels or open vessels (such as tower, tank and groove)

原理与结构

  TKWL-140系列液位计是基于连通器原理设计 的，由玻璃板及液位计主体通过法兰与被测容器相接构成连通器，透过玻璃板可观察到实际液位。液 位计主要由玻璃板、表体、压盖、上下阀门和法兰等组成的，由于玻璃板长度固定，所以通过改变玻璃板节数可制成不同规格的液位计。液位计配套的上下阀门不但起截止阀的作用，而且内置钢球在玻璃板意外破损时起自动关闭作用，防止液体或气体外泄。

Principle  andStructure

  TKWL-140 liquid level meter is designed based on the theoryof communicating vessels. The communicating vessel is formed by the connectionof the glass plate and the body of the liquid level meter through the flangeand the measured vessel. Through the glass plate, actual liquid level can beobserved. The liquid level meter is mainly composed of the glass plate, themeter body,  the  cover, upper and bottom valves as well as theflange. As the length of the glass plate is fixed, by changing the pitch numberof the glass plate, liquid level meters of different specifications can bemade.

  Not only can the matched upper and bottomvalves of the liquid level meter play the role of the stop valve, but theinside steel ball can also play the role of closing when the glass plate isdamaged accidentally in order to prevent escape of liquid or gas.
