Description

具开闭状态指示功能的球阀
技术领域
本发明属于阀门，更具体地说涉及一种具开闭状态指示功能的球阀。
背景技术
现有的球阀，其启闭是借手柄的逆时针方向或顺时针方向转动90度角实现，但是，有的球阀，当手柄位置与出液管重合时为全开态，有的球阀，则是当手柄位置与出液管成直角时为全开态，不相统一，还有，很多人虽然经常在用，但是一旦问他们开闭状态，却说不清。而实际生活或生产中往往要求球阀具有开闭状态指示功能，如物流系统的上游意外中止输送时，下游看不到有液体流出，处于全开态的球阀，易被误为是处于关闭状态，以致该关不关，一旦，上游恢复输送，往往会浪费物料或发生安全事故。
因此，提供一种具开闭状态指示功能的球阀，具有十分重要的意义。
发明内容
本发明的目的是提供一种具开闭状态指示功能的球阀。
本发明一种具开闭状态指示功能的球阀，包括带帽的旋转式手柄，阀主体，折扇样伸缩件，所述阀主体在所述帽旁垂直向上延伸设置有一根杆子，并且，所述杆子位于当所述球阀处关闭位时的所述手柄正下方，所述伸缩件一端经一边杆与所述杆子接合，另一端与所述手柄连接，所述伸缩件有四个折叠单元，所述球阀处于全开状态时，所述伸缩件全展，并在中心处呈现一个圆孔。
本发明有如下有益效果：
借所述伸缩件的形态，形象而直观地了解球阀的开闭状态，也有助于视力障碍者凭触觉感知。
附图说明
图1是本发明一种具开闭状态指示功能的球阀处于关闭态的侧视结构示意图。
图2是本发明一种具开闭状态指示功能的球阀处于全开态的俯视结构示意图。
图3是本发明另一实施例球阀处于全开态的俯视结构示意图。
图4是本发明所述伸缩件的立体结构示意图。
具体实施方式
下面结合附图对本发明作进一步的描述。
图1所示，一种具开闭状态指示功能的球阀，包括带帽1的旋转式手柄2，阀主体3，折扇样伸缩件4，所述阀主体3在所述帽1旁垂直向上延伸设置有一根杆子5，并且，所述杆子5位于当所述球阀处关闭位时的所述手柄2正下方，所述伸缩件4一端经一边杆6与所述杆子5接合，另一端与所述手柄2连接，如粘连，所述伸缩件4有四个折叠单元，所述球阀处于全开状态时，所述伸缩件4全展，并在中心处呈现一个圆孔7。
图1，图2所示，适合于当所述手柄2位置与出液口8成90度角时为全开态的球阀。
图3适合于当所述手柄2位置与出液口8重合时为全开态的球阀。
所述伸缩件4由织物或塑料片制成，虽然，折叠单元为二个时更易压缩，但是，全缩时，侧旁可见到半圆孔，让人误解，当折叠单元为四个时，如图4所示，则所述球阀处于关闭状态时，侧旁见不到半圆孔，而且，仍然容易压缩，当折叠单元为大于四个时，则压缩不能如意。
