Description

刀型闸阀
技术领域
本实用新型涉及阀门领域,具体属于刀型闸阀。
背景技术
刀型闸阀的启闭件是闸板,闸板的运动方向与流体方向相垂直,闸阀只能作全开和全关,不能作调节和节流。闸板有两个密封面,最常用的模式闸板阀的两个密封面形成楔形、楔形角随阀门参数而异,楔式闸阀的闸板可以做成一个整体,叫做刚性闸板;也可以做成能产生微量变形的闸板,以改善其工艺性,弥补密封面角度在加工过程中产生的偏差,这种闸板叫做弹性闸板。
实用新型内容
本实用新型的目的是提供刀型闸阀,结构设计简单,制造方便,密封性能好,保证了闸阀工作的稳定性。
本实用新型的技术方案如下:
刀型闸阀,包括有阀体,阀体的两端分别为进口端、出口端;阀体上安装有阀座,阀座中穿过有阀杆,阀杆的下端连接刀形的阀板,阀板的后侧垫置有密封圈。
本实用新型设置有采用刀形的阀板作为闸门,结构设计简单,制造方便,密封性能好,保证了闸阀工作的稳定性。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
参见附图,刀型闸阀,包括有阀体1,阀体1的两端分别为进口端2、出口端3;阀体上安装有阀座4,阀座4中穿过有阀杆5,阀杆5的下端连接刀形的阀板6,阀板6的后侧垫置有密封圈7。
