200Z41w25p Valve Design
[Abstract] The use of gatevalves isvery important in modern production, and its figure is ubiquitous in human production and life.
The research of gatevalve can promote human economic production, greatly improve economic efficiency and save energy in all kinds of production systems. How to design and select gatevalve correctly is the key to realize the sealing performance, adjusting performance, practical energy, safety performance and circulation performance of gatevalve. In this design, mainly on thevalve body,valve plate, dense cover and so on to understand and design, through the media temperature, pressure, corrosion and other factors, thevalve of the general special parts are calculated and designed. Finally, the accuracy of thevalve requirements, manufacturing, acceptance and assembly of the understanding and understanding, so that thevalve as awhole can play the most perfect results
