一、概述随着我国化工和炼油工业的蓬勃发展,对各种测量仪表的要求以及对各种特殊介质和参数测量的要求也日益提高。在许多企业的科研和工业生产过程中要经常测量和控制各种介质(液体、气体和蒸气)的流量,特别是易燃易爆的气体,不仅要提供保证安全、可靠的依据同时也是高产优质、企业的经济核算的一个重要依据。本文介绍的小1/4园喷嘴(习惯又称内藏孔板)是我厂新研制的产品之一。目前在国内也是小流量测量的一个新品种。
I. Overview As China’s chemical and refining industries booming, the requirements of a variety of measuring instruments and a variety of special media and parameter measurement requirements are also increasing. In many enterprises, the flow of various media (liquids, gases and vapors), especially flammable and explosive gases, should be measured and controlled frequently in the scientific research and industrial production. It not only provides the basis for guaranteeing safety and reliability, but also high yield and good quality , An important basis for business accounting. This article describes the small 1/4 Park nozzle (also known as built-in orifice) is one of our newly developed products. Currently in the country is also a small flow measurement of a new breed.
