油罐阻油切水阀启动过程的研究

A Study on Actuation of the Water-Draining Valve for Oil Storage Tanks

本文对油罐本安型阻油切水阀研制过程中的几个技术关键之一～二次启动进行了较详细的力学分析，研究了阻油切水阀的启动过程，分析了启动过程中液体在静止和流动两种情况下对浮球工作的影响，提出了启动机构方案。

The paper expounds on one of the key problems for the oil check valve-the actuation of the valve after a preceeding action of the oil-check process. The paper provides a dynamic analysis of the actuating process of the valve and the ball-float behavior in the flowing and non-flowing fluid.The design of the actuating mechnism of the valve is also introduced in this paper.
