Description

压力自密封闸阀
技术领域
本发明涉及一种阀门，尤其涉及一种压力自密封闸阀。
背景技术
为了有效地切断管道内的流体，在管道上都会设置有阀门。现有的阀门在打开关闭过程中摩擦力较大，密封效果差，维修不方便，使用寿命短，不能很好地满足使用要求。
发明内容
本发明所要解决的技术问题是：提供一种密封效果好的压力自密封闸阀。
为了解决上述技术问题，本发明采用的技术方案是：压力自密封闸阀，包括：阀体，在所述阀体内设置有通道，在所述通道的中部阀体内倾斜设置有阀座，在所述阀体内设置有与阀座相互配合的闸板，在所述闸板上设置有若干弹性凹槽，闸板与阀杆的一端相连接，阀杆的另一端伸出阀盖与阀杆操作机构相连接，所述阀盖通过阀母设置在阀体内，在所述阀母与阀盖之间设置有软不锈钢密封环，所述软不锈钢密封环的下端设置有斜面与阀盖上端的斜面相互配合，在所述阀盖的上端斜面上设置有硬质合金。
本发明的优点是：上述压力自密封闸阀安装在管道上，操作过程中摩擦力小，密封效果好，维修方便，使用寿命长，可以很好地满足使用要求。
附图说明
图1为本发明压力自密封闸阀的结构示意图。
图中：1、阀体，2、通道，3、阀座，4、闸板，5、弹性凹槽，6、阀杆，7、阀盖，8、阀杆操作机构，9、阀母，10、软不锈钢密封环，11、硬质合金。
具体实施方式
下面结合附图和具体实施例详细描述一下本发明的具体内容。
如图1所示，压力自密封闸阀，包括：阀体1，在所述阀体1内设置有通道2，在所述通道2的中部阀体1内倾斜设置有阀座3，在所述阀体1内设置有与阀座3相互配合的闸板4，在所述闸板4上设置有若干弹性凹槽5，闸板4与阀杆6的一端相连接，阀杆6的另一端伸出阀盖7与阀杆操作机构8相连接，所述阀盖7通过阀母9设置在阀体1内，在所述阀母9与阀盖7之间设置有软不锈钢密封环10，所述软不锈钢密封环10的下端设置有斜面与阀盖7上端的斜面相互配合，在所述阀盖7的上端斜面上设置有硬质合金11。
上述压力自密封闸阀安装在管道上，通过阀杆操作机构8向上提升阀杆6，从而带动闸板4向上运动直至通道2被打开，当流体在阀体1内经过时，会对阀盖7产生向上的推力，推力越大，阀盖7在软不锈钢密封环10和硬质合金11的作用下密封性能越好，不会发生流体泄漏，当需要关闭阀门时，通过阀杆操作机构8向下挤压阀杆6，从而带动闸板4向下运动直至通道2被阻断，闸板4与阀座3之间为倾斜结构，更容易插入减小摩擦，闸板4上的弹性凹槽5对闸板4本身有向外的张力，使阀座3与闸板4之间的配合更加紧密，密封效果加强。
