冷壁单动滑阀高温区内件失效原因与对策

Failure Causes and Countermeasures of Internals in High Temperature Zone of Cold Wall Single-acting Slide Valve

冷壁单动滑阀是滑阀中的重要类型之一,也是目前炼油企业常用的滑阀类型,是炼油化工生产中,重要的催化裂化装置之一,其运行状况直接影响企业生产质量和生产安全。冷壁单动滑阀高温区内件在其中发挥关键性作用,但受到多因素的影响,一旦出现失效问题将阻碍滑阀的正常运行,因此,必须采取有效的修复对策加以解决。对此,文章分析了冷壁单动滑阀结构特点及应用,并从多个方面重点研究了冷壁单动滑阀高温区内件失效原因与对策。

The cold-wall single-acting slide valve is one of the important types of slide valves,and is also the commonly used slide valve type in oil refining enterprises.It is one of the most important catalytic cracking units in oil refining and chemical production,and its operation status directly affects the production quality and safety of enterprises.The internals in the high temperature zone of the cold-wall single-acting slide valve play a key role,but are affected by many factors.Once the failure occurs,it will hinder the normal operation of the slide valve.Therefore,effective repair measures must be taken to solve it.In this regard,the article analyzes the structural characteristics and application of the cold-wall single-acting slide valve,and focuses on the causes and countermeasures of the failure of the internals in the high-temperature zone of the cold-wall single-acting slide valve from various aspects.
