Abstract

本实用新型公开了一种石化闸阀,包括有阀体,所述的阀体内有闸座,闸座内安装有楔形闸板,所述的闸板与闸座的接触面为弹性密封面,所述的阀体上方安装有阀盖,所述的阀盖上安装有阀杆座,阀杆座上螺合有阀杆,阀杆上端安装有手轮,所述的阀杆下端与阀盖之间采用填料密封,阀杆下端与闸板之间转动连接。本实用新型采用闸板与闸座的接触面为弹性密封面,不仅可弥补密封面角度在加工过程中产生的偏差,增强密封效果,还可以减少闸板与闸座相接触的两密封面之间的相对摩擦,延长密封件的使用寿命。

Description

石化闸阀
技术领域
本实用新型属于一种阀门,具体是一种石化闸阀。
背景技术
闸阀是指关闭件(闸板)沿通路中心线的垂直方向移动的阀门。闸阀在管路中只能作全开和全关切断用,不能作调节和节流。闸阀是使用范围很广的一种阀门,一般口径DN≥50mm的切断装置都选用它。但现有的闸阀启闭时,闸板与闸座相接触的两密封面之间有相对摩擦,易损伤,影响密封件的使用寿命,维修比较困难。
实用新型内容
本实用新型的目的是提供一种石化闸阀,可增强密封效果,减少闸板与闸座相接触的两密封面之间的相对磨擦,延长密封件的使用寿命。
本实用新型的技术方案如下:
石化闸阀,包括有阀体,所述的阀体内有闸座,闸座内安装有楔形闸板,所述的闸板与闸座的接触面为弹性密封面,所述的阀体上方安装有阀盖,所述的阀盖上安装有阀杆座,阀杆座上螺合有阀杆,阀杆上端安装有手轮,所述的阀杆下端与阀盖之间采用填料密封,阀杆下端与闸板之间转动连接。
与现有技术相比,本实用新型采用闸板与闸座的接触面为弹性密封面,不仅可弥补密封面角度在加工过程中产生的偏差,增强密封效果,还可以减少闸板与闸座相接触的两密封面之间的相对磨擦,延长密封件的使用寿命。
附图说明
图1为本实用新型结构示意图。
具体实施方式
石化闸阀,包括有阀体1,所述的阀体1内有闸座2,闸座2内安装有楔形闸板3,所述的闸板3与闸座2的接触面为弹性密封面,所述的阀体1上方安装有阀盖4,所述的阀盖4上安装有阀杆座5,阀杆座5上螺合有阀杆6,阀杆6上端安装有手轮7,所述的阀杆6下端与阀盖4之间采用填料密封,阀杆6下端与闸板3之间转动连接。使用时,手轮7转动带动阀杆6转动,阀杆6带动闸板3运动实现管道的开和关。
