Description

一种增强法兰高温变形密封性的密封垫
技术领域
本发明属于高温炉法兰密封技术领域，具体的说，涉及一种增强法兰高温变形密封性的密封垫。
背景技术
TKAS镀锌线具有镀锌和镀铝两种产品，镀铝生产时炉鼻子温度高达650℃以上，远远超过镀锌生产时的460℃，在高温环境下炉鼻子及炉鼻子保温段法兰变形严重，最大变形量14mm，而正常的密封垫仅有2mm厚，更换新炉箅子后，法兰处泄漏，炉内露点及氧含量异常，造成产品脱锌及降级。如何补偿及消除法兰大变形量以达到密封效果是迫切需要解决的问题。
发明内容
为解决以上技术问题，本发明的目的在于提供一种增强法兰高温变形密封性的密封垫，是一种高补偿量的密封垫，消除炉箅子法兰变形量，并达到0泄漏的密封效果。
本发明目的是这样实现的：一种增强法兰高温变形密封性的密封垫，其关键在于：包括至少两层紫铜板层和至少一层耐火纤维层，相邻的所述紫铜板层之间夹设一层所述耐火纤维层。
进一步地，上述紫铜板层的层状结构为整块紫铜板内弧弯曲折叠成。
进一步地，上述耐火纤维层为摩根高维纸。
进一步地，上述的增强法兰高温变形密封性的密封垫，由整块的紫铜板内弧弯曲折叠成4层所述紫铜板层和3层分别位于相邻紫铜板层之间的所述耐火纤维层组成。
进一步地，上述紫铜板层的单层厚度为2mm，所述耐火纤维层单层厚度为6mm。
有益效果：
1、密封垫可采用退火的2mm厚紫铜板制作，内弧弯曲共4层、中间夹3层6mm厚摩根高维纸，总厚度为26mm，在两片法兰压紧时，内弧面的紫铜板将嵌入高维纸内，达到密封效果。同时法兰的螺栓可同步地使用12.8级M20高强螺栓，利用螺栓强度恢复法兰变形。
2、安装完成后，用便携式氢气检测仪检测泄漏量，法兰泄漏为0ppm。炉内氧含量由200ppm降为12ppm，露点由-17℃降为-42℃，炉内气氛正常。
附图说明
图1为本发明的结构示意图；
其中1为紫铜板层、2为耐火纤维层。
具体实施方式
下面结合实施例和附图对本发明作进一步说明。
实施例：
如图1所示：一种增强法兰高温变形密封性的密封垫，由整块的紫铜板内弧弯曲折叠成4层的紫铜板层1和3层分别位于相邻紫铜板层1之间的耐火纤维层2组成。所述紫铜板层1的单层厚度为2mm，所述耐火纤维层2单层厚度为6mm。所述耐火纤维层2为摩根高维纸。
最后需要说明的是，上述描述仅仅为本发明的优选实施例，本领域的普通技术人员在本发明的启示下，在不违背本发明宗旨及权利要求的前提下，可以做出多种类似的表示，如紫铜板层、耐火纤维层的层数等，这样的变换均落入本发明的保护范围之内。
