Description

氮化硅陶瓷球阀硬密封结构
技术领域
本实用新型涉及阀门技术领域,尤其涉及球阀技术领域。
背景技术
球阀大都采用金属材质,阀座与阀芯之间的密封面并没有进行精细加工,在高温、腐蚀、冲刷工况下使用,经常会出现泄漏现象。
实用新型内容
为了解决现有球阀经常会出现泄漏的问题,本实用新型提供了一种氮化硅陶瓷球阀硬密封结构。
本实用新型为实现上述目的所采用的技术方案是:氮化硅陶瓷球阀硬密封结构,阀芯2安装于阀座1上,阀芯2上设有阀杆孔3,阀座1上与阀芯2的球面接触处设有密封层4。
所述密封层4为氮化硅陶瓷密封层。
本实用新型的氮化硅陶瓷球阀硬密封结构,密封面设有超精加工密封层,使阀座接触面和阀芯球面紧密密合,有效的使用在高温、腐蚀等恶劣环境。
附图说明
图1是本实用新型氮化硅陶瓷球阀硬密封结构图。
图中:1、阀座,2、阀芯,3、阀杆孔,4、密封层。
具体实施方式
本实用新型的氮化硅陶瓷球阀硬密封结构如图1所示,阀芯2安装于阀座1上,阀芯2上设有阀杆孔3,阀座1上与阀芯2的球面接触处设有密封层4,密封层4为氮化硅陶瓷密封层。
本实用新型的氮化硅陶瓷球阀硬密封结构,密封面设有超精加工密封层,使阀座接触面和阀芯球面紧密密合,利用氮化硅自身的耐腐蚀、耐磨以及耐高温的性能,使该球阀硬密封长时间在工况恶劣的环境下使用。
