一、前言闸门和阀是水工建筑物上重要的组成部分之一,它用以控制或调节水流。以往我们在这方面所做的工作很少,特别是高水头的闸门和阀。随着国家建设事业的发展,它们的需要就愈来愈多了,因此对它们的发展作一简单的回顾,以了解它们的性能、存在的问题、改善的办法和发展的趋势是很必要的。它可以使我们在工作中少走许多弯路,节省许多人力、物力以及宝贵的时间。由于作者水平有限,文中罗列的材料不够全面、只能说是一个开端,一个尝试,希望同志们进行补充和讨论。
I. INTRODUCTION Gates and valves are one of the most important components of hydraulic structures that control or regulate the flow of water. In the past we have done very little in this area, especially high-head gates and valves. With the development of the country’s construction, their needs are growing. Therefore, it is necessary to make a brief review of their development so as to understand their performance, existing problems, improvement measures and development trends . It can make us take less detours at work and save a lot of manpower, material resources and precious time. Due to the author’s limited level, the materials listed in the article are not comprehensive enough to be described as a beginning, an attempt and hope that the comrades will supplement and discuss it.
