Abstract
This article is a straight-through stop valve design. Straight-through stop valve, it relies on stem pressure on the valve sealing surface is closely integrated with the valve seat sealing surface to prevent the media flow. In the process of opening and closing the small friction between the sealing surface, wear and opening height is small, manufacturing process performance is good. It is the most widely used industrial sector as a valve. This article made reference to the literature about the many valves and valve manufacturer in the actual production over the years accumulated practical experience, and characteristics of the type of valve, the structure, size, and sealing methods of straight-through stop valve are explained in detail, And understand how it works. I chose bronze flanged straight-through stop valve design as my design subject. According to the design require
