闸阀
摘要：
本发明提供一种闸阀，该闸阀包括：阀盖、轴承、盖板以及阀杆；阀盖上设置有轴承孔，轴承孔的底端设置有止挡凸缘，轴承设置在轴承孔内，且轴承的底端抵顶在止挡凸缘上；阀杆穿设在轴承孔内，阀杆上设置有第一止挡部，第一止挡部抵顶在轴承的顶端；阀杆上可拆卸的设置有第二止挡部，第二止挡部位于止挡凸缘的下部；盖板设置在轴承孔的顶端，盖板可拆卸的与阀盖连接。当阀杆因被腐蚀而断裂时，第二止挡部抵顶在止挡凸缘上，以阻止阀杆由轴承孔内飞出，避免对操作人员造成伤害。
摘要（英）：

The invention provides a gate valve. The gate valve comprises a valve cover, a bearing, a cover plate and a valve rod. A bearing hole is formed in the valve cover. A stopping flange is arranged at thebottom end of the bearing hole. The bearing is arranged in the bearing hole. The bottom end of the bearing abuts against the stopping flange. The valve rod penetrates through the bearing hole. A first stopping part is arranged on the valve rod and abuts against the top end of the bearing. A second stopping part is detachably arranged on the valve rod and is positioned on the lower portion of thestopping flange. The cover plate is arranged at the top end of the bearing hole and is detachably connected with the valve cover. When the valve rod is broken due to corrosion, the second stopping part abuts against the stopping flange so as to prevent the valve rod from flying out of the bearing hole, and damage to operators is avoided.
