Abstract

本实用新型提供了一种高压球阀，包括阀体、扳手，在阀体的进口通道和出口通道的侧面开有安装孔，安装孔上分别装有连通管道，在连通管道之间还装有一截止阀，球阀的扳手与截止阀的手柄位于同一平面且相互平行，二者通过连杆和销连接为一体。本实用新型的有益效果是通过截止阀的旁通作用，平衡介质压力，阀门启闭扭矩小，操作轻便，阀门使用寿命长。

Description

一种高压球阀
技术领域
本实用新型涉及一种球阀，尤其是是一种高压球阀。
背景技术
目前在使用在石化、核电领域的高压球阀，靠安装在阀体上的弹簧推动阀座与球体密封面接触实现初始密封，工作时靠介质压力实现自力式密封。由于介质压力大，阀门开启时扭矩大，操作困难。
发明内容
为了克服现有由于工作时介质压力大，阀门开启扭矩大，操作困难的不足，本实用新型提供一种开启扭矩小，操作轻便的高压球阀。
本实用新型解决其技术问题所采用的技术方案是一种高压球阀，包括阀体、扳手，在阀体的进口通道和出口通道的侧面开有安装孔，安装孔上装有连通管道，在连通管道之间还装有一截止阀。
球阀的扳手与截止阀的手柄位于同一平面且相互平行，二者通过连杆和销连接为一体。
本实用新型的有益效果是通过截止阀的旁通作用，平衡介质压力，阀门启闭扭矩小，操作轻便，阀门使用寿命长。
附图说明
下面结合附图和实施例对本实用新型作进一步说明。
图1是本实施例的构造图；
图2是图1的俯视图。
图中：1.扳手；2.截止阀；3.阀体；4.连接管道；5.连杆；6.安装孔；7.销；8.手柄。
具体实施方式
如图1和图2所示，一种高压球阀，包括阀体3、扳手1，在阀体3的进口通道和出口通道的侧面开有安装孔6，安装孔6上分别装有连通管道4，在连通管道4之间还装有一截止阀2。
球阀的扳手1与截止阀2的手柄8位于同一平面且相互平行，二者通过连杆5和销7连接为一体。要开启阀门时，转动扳手1，通过连杆5和销7的作用，带动截止阀2的手柄8一起转动，截止阀2打开，高压介质通过截止阀2的旁通，平衡了阀门球体两侧的压力，大大减小了阀门开启扭矩，操作轻便，使用寿命长。
