Abstract

本发明公开了一种闸阀，包括旋转式手轮(1)，阀体(2)，阀盖(3)，阀板(4)，阀杆(5)，填料压紧螺母(6)，乳胶环(7)，所述阀杆(5)中心有上下向穿孔，所述穿孔插有升降杆(8)，所述升降杆(8)下端连接所述阀板(4)之下端，所述升降杆(8)上端连接指示球(9)，所述阀杆(5)的下端在所述穿孔周围设置有圆环状凹陷(10)，所述乳胶环(7)下部上下向一体化交替形成有数个环所述升降杆(8)的薄壁与厚壁，所述乳胶环(7)让所述升降杆(8)紧密穿过后，其上端紧密插接在所述凹陷(10)内。借所述指示球(9)高位于所述手轮(1)顶面，或低位于所述手轮(1)顶面，直观地反映所述闸阀的启闭状态。

Description

一种闸阀
技术领域
本发明属于阀门，更具体地说涉及一种闸阀。
背景技术
现有的闸阀其启闭是借旋转式手轮的逆时针方向或顺时针方向转动实现，所述手轮，虽然，标有关于启闭的施力方向指示，但是，不具有关于启闭状态的指示功能，而实际生产中往往要求闸阀具有这种功能，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，处于开启状态的闸阀，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，往往会浪费或发生安全事故。
发明内容
本发明的目的是提供一种闸阀。
本发明一种闸阀，包括旋转式手轮，阀体，阀盖，阀板，阀杆，填料压紧螺母，乳胶环，所述阀杆中心有上下向穿孔，所述穿孔插有升降杆，所述升降杆下端连接所述阀板之下端，所述升降杆上端连接指示球，所述阀杆的下端在穿孔周围设置有圆环状凹陷，所述乳胶环下部上下向一体化交替形成有数个环所述升降杆的薄壁与厚壁，所述乳胶环让所述升降杆紧密穿过后，其上端紧密插接在所述凹陷内。
本发明有如下有益效果：
借所述指示球高位于所述手轮顶面，或低位于所述手轮顶面，直观地反映所述闸阀的启闭状态，也有助于视力障碍者凭触觉感知。
附图说明
图1是本发明闸阀的开启态结构示意图。
图2是本发明闸阀的关闭态结构示意图。
图3是本发明中所述乳胶环与所述升降杆，所述阀杆间的结合效果示意图。
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或图2，图3所示，一种闸阀，包括旋转式手轮1，阀体2，阀盖3，阀板4，阀杆5，填料压紧螺母6，乳胶环7，所述阀杆5中心有上下向穿孔，所述穿孔插有升降杆8，所述升降杆8下端连接所述阀板4之下端，所述升降杆8上端连接指示球9，所述阀杆5的下端在所述穿孔周围设置有圆环状凹陷10，所述乳胶环7下部上下向一体化交替形成有数个环所述升降杆8的薄壁与厚壁，所述乳胶环7让所述升降杆8紧密穿过后，其上端紧密插接在所述凹陷10内。
当所述阀板4提升至最高位时，所述指示球9高位于所述手轮1顶面，如图1所示，虽然，可能会顶触到使用者手心，但是，丝毫不会影响对所述手轮1的操作，因为，使用者手心在操作时是呈上拱状的，当所述阀板4下降至最低位时，则所述指示球9低位于所述手轮1顶面，如图2所示。
各薄壁厚度为0.3-0.8毫米，两厚壁间距离为1.2-1.8毫米。
所述乳胶环7有数个薄壁，则所述乳胶环7下部在所述阀体内的液态物料压力作用下，能始终贴紧所述升降杆8，防止液态物料从所述阀杆5与所述升降杆8间向上漏出。
所述乳胶环7如无薄壁，则难以保障所述乳胶环7与所述升降杆8间的紧密，影响密封效果，所述薄壁如是单个，则在所述升降杆8在升降时会缩皱，影响所述乳胶环7使用寿命，所述薄壁如是数个，则所述升降杆8升降时因受薄壁上下的各厚壁阻挡，使缩皱非常有限。
