图中：1、阀体，2、左阀盖，3、右阀盖，4、填料箱，5、球体，6、阀座圈，7、阀杆，8、预紧弹簧，9、三角密封圈，10、泄压阀，11、四开卡环。
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，全焊接固定球阀，包括：阀体1，设置在阀体1的左右两侧的左阀盖2和右阀盖3和设置在阀体1上端的填料箱4，所述的阀体1与左阀盖2、右阀盖3和填料箱4之间都是焊接连接，在所述阀体1内部设置在球体5和阀座圈6，在阀体1、左阀盖2、右阀盖3和阀座圈6内各设置有流道，所述球体5与阀杆7的下端相连接，所述阀杆7的上端与阀杆驱动装置相连接，在所述阀座圈6设置有预紧弹簧8和与球体5相互配合的三角密封圈9，所述三角密封圈9的三个角处为弧形面，在所述的球体5上设置有泄压阀10。
上述全焊接固定球阀，由阀杆驱动装置驱动阀杆7带动球体5绕轴线转动，当球体5流道与阀体1、左阀盖2和右阀盖3流道相垂直时，阀门关闭。当球体5流道与阀体1、左阀盖2和右阀盖3流道相相连时，阀门开启。
在本实施例中，所述的填料箱4的下端设置有四开卡环11，起到很好的固定和密封效果。
所述的阀体1与左阀盖2、右阀盖3和填料箱4之间都是焊接连接，可以有效防止介质外漏，结构合理。
所述三角密封圈9的三个角处为弧形面，材料采用AED，能耐200℃的温度，且密封面与球体5接触部位采用线接触面，密封效果好。
阀门开启时，预紧弹簧8预紧阀座圈6和球体5，使三角密封圈9与球体5表面紧贴，双向密封，球体5的中腔通过泄压阀10自动泄压。同样，阀门关闭时，二侧都有介质压力作用时，两侧阀座圈6分别推向球体5两侧，能实现双向密封。
