一、概述随着我国国民经济的发展,要求我国机械工业能自行提供大型氮肥厂的成套设备,以便生产更多的氮肥,供应农业增产粮食,促进农业的大发展。高压容器是大型氮肥厂(如30万吨/年合成氨厂)中的关键设备之一。高压密封及其连接方式又是高压容器的重要组成部分,其密封一般均采用平垫、双锥、△等结构。联接结构多采用主螺栓方式。它的缺点是二级精度的大螺

I. General With the development of our national economy, China’s machinery industry is required to provide complete sets of equipment for large-scale nitrogenous fertilizer plants in order to produce more nitrogenous fertilizer, supply agricultural products for grain production and promote the great development of agriculture. High-pressure vessel is one of the key equipment in a large-scale nitrogen fertilizer plant (such as 300,000 tons / year ammonia plant). High pressure seal and its connection is an important part of the high pressure container, the seal are generally used flat pad, double cone, △ and other structures. The use of the main structure of the bolt connection. Its disadvantage is the second level of large spiral
