Some of the common pressure vessels used in the Site are: separators used to separate liquid and vapor, heat exchangers used to transfer heat from a hotter fluid to a cooler fluid, reactors in which chemical or catalytic reactions take place during conversion-type processes, distillation towers, filters, crystallizers, and so on. Regardless of the nature of the application of the vessel, a number of factors usually must be considered in the design and operation of the vessel for the required service. This module will focus on the two major categories of pressure vessels:压力容器可简单定义为可以耐受内部压力或外部压力的容器。
压力容器英文：pressure vessel1.概述工业生产中具有特定的工艺功能并承受一定压力的设备，称压力容器。
贮运容器、反应容器、换热容器和分离容器均属压力容器。
为了与一般容器(常压容器)相区别，只有同时满足下列三个条件的容器，才称之为压力容器：（1）最高工作压力（Pw）（注1）大于等于0.1Mpa(不含液体静压力,下同);（2）内直径(非贺形截面指其最大尺寸)大于等于0.15m,且容积(V)(注2)大于等于0.25m3;（3）盛装介质为气体液化气体或最高工作温度高于等于标准沸点液体.压力容器的用途十分广泛。
它是在石油化学工业、能源工业、科研和军工等国民经济的各个部门都起着重要作用的设备。
压力容器一般由筒体、封头、法兰、密封元件、开孔和接管、支座等六大部分构成容器本体。
此外，还配有安全装置、表计及完成不同生产工艺作用的内件。
压力容器由于密封、承压及介质等原因，容易发生爆炸、燃烧起火而危及人员、设备和财产的安全及污染环境的事故。
目前，世界各国均将其列为重要的监检产品，由国家指定的专门机构，按照国家规定的法规和标准实施监督检查和技术检验。
2.分类压力容器的分类方法很多，从使用、制造和监检的角度分类，有以下几种。
(1)按承受压力的等级分为：低压容器、中压容器、高压容器和超高压容器。
(2)按盛装介质分为：非易燃、无毒；易燃或有毒；剧毒。
(3)按工艺过程中的作用不同分为：①反应容器：用于完成介质的物理、化学反应的容器。
②换热容器：用于完成介质的热量交换的容器。
③分离容器：用于完成介质的质量交换、气体净化、固、液、气分离的容器。
④贮运容器：用于盛装液体或气体物料、贮运介质或对压力起平衡缓冲作用的容器。
(4)为了更有效地实施科学管理和安全监检，我国《压力容器安全监察规程》中根据工作压力、介质危害性及其在生产中的作用将压力容器分为三类。
并对每个类别的压力容器在设计、制造过程，以及检验项目、内容和方式做出了不同的规定。

由于存在火花点燃风险，对液态氧和气态氧的处理具有一定的挑战性。
行业需要的解决方案不仅要具备高性能、高可靠性和耐用性，同时还要达到严格的清洁度要求。
VANESSA 三偏心阀门解决方案适用于在富氧工况中安全可靠地进行隔断和工艺调节在空分装置 (ASU) 的内部及周围，液态氧 (LOX) 是低温蒸馏过程的直接产物，该过程在转化为气态氧 (GOX) 之前进行。
以上过程在热交换器中发生，随后气态氧被运输并用于高炉、化学反应器和许多其它工业应用中。
通常情况下，这些应用面临着影响工厂生产力、安全性、可靠性的问题：使用一个不合格的阀门可能会导致一场重大事故的发生。
可靠的氧气工况阀门必须选择合适的材料，还要满足严格的清洁度要求，才能在液态氧 (LOX) 的低温环境和气态氧 (GOX) 的高压环境中实现出色的隔断和调节性能。
在传统阀门设计中，升降式阀杆和阀体腔可能会有外部颗粒进入，并存在氧相变的风险，可能引起燃烧。
传统的球阀和高性能蝶阀设计尽管已经在液态氧中得到了应用，但在密封过程中仍会存在机械摩擦，这是另一个可能的引燃原因。
球阀也在气态氧 (GOX) 中作为传统阀门广泛应用，但会产生较高的总体安装费用（由于占用空间大、重量重和所需的大扭矩驱动）及高昂的维护成本。
液体储罐空气压缩装置吸附装置热交换器蒸馏塔图 1空分装置产品信息三偏心设计Vanessa 30,000 系列阀门与截止阀具有相同的锥对锥原理，但其密封通过角行程旋转完成。
三偏心阀的密封系统由外形相同（具有倾斜的锥形截面）的固定阀座和旋转密封面组成。
当这两个锥面重叠时，因达到关闭位置而实现密封。
这种"角行程截止阀"的概念是通过使用三个可完全消除摩擦的"偏心"来实现的。
在所有基础、低温和高温配置中将三偏心设计和柔性金属密封环巧妙组合，产品通过优化的阀座角度和旋转特性，从而确保了卓越的密封性。
密封环Vanessa 30,000 系列密封环的弹性和径向压缩使接触压力均匀地分布在阀座表面 - 确保零泄漏*性能。
