Description

一种石化设备密封衬垫
技术领域
本实用新型涉及一种密封件,尤其涉及一种石化设备密封衬垫。
背景技术
目前,在石油化工设备中,用于换热器等大直径管口静密封处的环形密封垫有两种,一种使铁包石棉垫,一种是柔性石墨缠绕垫。前者强度高,但对密封部位的精度要求亦高,经使用后的设备,一但表面变得粗糙或者有微小的划痕,则铁包石棉垫对该处的密封就难以保证,易发生泄漏,后者能进行柔性密封,不易泄漏,但本身强度低,对安装条件要求高,螺栓稍过紧,石墨垫会散架,过松又不能很好的密封。
实用新型内容
本实用新型为了解决以上问题提供了一种结构简单、密封性能好、防腐耐磨、防水防漏、生产成本低、使用寿命长的石化设备密封衬垫。
本实用新型的技术方案是:所述的密封衬垫包括石棉内芯层,所述的石棉内芯层外设置有不锈钢缓冲层,所述的不锈钢缓冲层外设有石墨衬垫密封层,所述的石墨衬垫密封层外设置有防腐耐磨层。
本实用新型结构简单、密封性能好、防腐耐磨、防水防漏、生产成本低、使用寿命长。
附图说明
图1是本实用新型的结构示意图。
图中1是石棉内芯层,2是不锈钢缓冲层,3是石墨衬垫密封层,4是防腐耐磨层。
具体实施方式
一种石化设备密封衬垫,所述的密封衬垫包括石棉内芯层1,所述的石棉内芯层1外设置有不锈钢缓冲层2,所述的不锈钢缓冲层2外设有石墨衬垫密封层3,所述的石墨衬垫密封层3外设置有防腐耐磨层4。
