喷嘴挡板式定位器之喷嘴理论与计算机模拟分析

Nozzle baffle type positioner of the nozzle theory and computer simulation analysis

随着国民经济快速发展,工业过程控制自动化程度越来越高,作为主要的过程控制仪表,调节阀和定位器的应用范围越来越广。定位器的主要作用是控制调节阀的行程,是调节阀必不可少的控制元件。本文介绍了定位器中一个重要部件喷嘴挡板设计参数的理论计算,并加以计算机模拟分析验证。

Along with the fast development of national economy, industrial process control automation degree is more and more high, as the main process control insmm^nt, control valve and positioner the application scope of more and more widely. Locator is mainly used to control valve on the itinerary, a regulator indispensable control element. This paper introduces the locator an important component nozzle baffle design parameters of theoretical calculation, and to computer simulation analysis and testing.
