Abstract

一种密封法兰,主要用于具有压力的设备或具有压力的管道阀门或安全放散阀的密封,它包括一块钢板,其特征是钢板上设有截面呈梯形的凹槽,凹槽内设有截面呈梯形的密封垫。本实用新型截面呈梯形的凹槽为外小内大,密封垫嵌在凹槽内,不易被气流吹得脱落,从而延长了本实用新型的使用寿命。

Description

一种密封法兰
技术领域:
本实用新型具体涉及一种密封法兰,主要用于具有压力的设备或具有压力的管道阀门或安全放散阀的密封。
背景技术:
具有压力的设备或具有压力的管道阀门或安全放散阀的密封法兰的结构是在钢板上设有截面呈矩形的凹槽,凹槽内设有密封垫。这种结构的密封法兰的密封垫经常在运行中被气流吹得脱离位置,导致管道阀门或安全放散阀泄漏。
发明内容:
本实用新型提供密封垫不易脱落的一种密封法兰。
实现本实用新型的技术方案是:包括一块钢板,其特征是钢板上设有截面呈梯形的凹槽,凹槽内设有截面呈梯形的密封垫。
本实用新型截面呈梯形的凹槽为外小内大,密封垫嵌在凹槽内,不易被气流吹得脱落,从而延长了本实用新型的使用寿命。
附图说明:
图1是本实用新型实施例的主视图。
图2是图1沿A-A向的剖面图。
图中:1.钢板  2.密封垫
具体实施方式:
实施例:图1所示,本实施例包括一块钢板1,其特征是钢板1上设有截面呈梯形的凹槽,密封垫2嵌在截面呈梯形的凹槽内,密封垫2为截面呈梯形的环形。
