Description

压力自密封截止阀
技术领域
本发明涉及一种阀门，尤其涉及一种压力自密封截止阀。
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。现有的阀门一般只有一种功能截止或者止回，功能比较单一，而且都是采用垂直结构，缓冲效果差，一些地方由于长时间接触磨损率高，导致阀门使用寿命缩短，同时阀杆与阀盖之间稳固性能差，控制不精确，阀体与阀盖之间的密封性能达不到要求，容易导致液体介质发生泄漏，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：提供一种缓冲效果好的压力自密封截止阀。为了解决上述技术问题，本发明采用的技术方案是：压力自密封截止阀，包括：阀体，在所述阀体内设置有进口通道和出口通道，在所述阀体内设置有与进口通道和出口通道相互配合的阀瓣，在阀瓣上设置有铬合金块，在阀杆的一端上设置有与铬合金块相互配合的圆弧凸起，阀瓣上的铬合金块与阀杆一端上的圆弧凸起相抵，阀杆的另一端伸出阀盖上的螺母与手柄相连接，所述螺母与阀盖之间通过固定螺钉相连接，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：上述压力自密封截止阀安装在管道上，同时具有截止阀和止回阀两种功能，摩擦力小，y型结构的缓冲效果好，维修方便，操作时稳固性能好，密封效果好，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截止阀的结构示意图。
图中：1、阀体，2、进口通道，3、出口通道，4、阀瓣，5、铬合金块，6、阀杆，7、圆弧凸起，8、阀盖，9、螺母，10、手柄，11、固定螺钉，12、阀母，13、软不锈钢密封环，14、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，压力自密封截止阀，包括：阀体1，在所述阀体1内设置有进口通道2和出口通道3，在所述阀体1内设置有与进口通道2和出口通道3相互配合的阀瓣4，在阀瓣4上设置有铬合金块5，在阀杆6的一端上设置有与铬合金块5相互配合的圆弧凸起7，阀瓣4上的铬合金块5与阀杆6一端上的圆弧凸起7相抵，阀杆6的另一端伸出阀盖8上的螺母9与手柄10相连接，所述螺母9与阀盖8之间通过固定螺钉11相连接，所述阀盖8通过阀母12设置在阀体1内，在所述阀母12与阀盖8之间设置有软不锈钢密封环13，所述软不锈钢密封环13的下端设置有斜面与阀盖8上端的斜面相互配合，在所述阀盖8的上端斜面上设置有硬质合金14。
上述压力自密封截止阀安装在管道上，流体通过进口通道2进入阀体1内，通过手柄10向上提升阀杆6，阀瓣4被流体顶开，进口通道2和出口通道3连通，当流体在阀体1内经过时，会对阀盖8产生向上的推力，推力越大，阀盖8在软不锈钢密封环13和硬质合金14的作用下密封性能越好，不会发生流体泄漏，阀杆与阀盖通过固定螺钉11二次连接，操作时更加稳固牢靠，当需要关闭阀门时，通过手柄10向下挤压阀杆6，阀瓣4在阀杆6的作用下使进口通道2和出口通道3被隔开，阀杆6一端的圆弧凸起7与铬合金块5相抵，降低了阀瓣4与阀杆6之间的磨损率，延长了阀门的使用寿命，阀瓣4受到流体的冲击力减少，起到了很好的缓冲作用。
