Abstract

一种带有蛇形皮管的密封闸阀,包括有阀座1、阀盖3、阀杆4、手轮5,其阀盖3上端用螺钉连接空心的压盖7,阀杆4外套有空心的波浪形的蛇形皮管2,蛇形皮管一端翻边被压盖7与阀盖3之间压住,另一端用皮管卡6卡住。与现有技术相比,结构紧凑,容易制作,使用寿命长,密封性好,防腐蚀等特点。

Description

带有蛇形皮管的密封闸阀
本实用新型涉及一种闸阀,尤其表现在能密封的带有蛇形皮管的密封闸阀。
目前市场上所售的闸阀,使用不久就容易从阀杆外泄介质,造成能源浪费,也带来隐患。在专利申请号96234798.1专利公开了“一种抗磨损旋塞渣浆阀门”,仍然存在着多次转动阀杆,使密封件硬性磨擦多次,造成损坏,使介质外泄不足之外。
针对上述存在不足之处,本实用新型的目的是提供一种结构简单,容易制作,并能有效密封的带有蛇形皮管的密封闸阀。
本实用新型的目的是这样实现的,包括有阀座、阀盖、阀杆、手轮,其阀盖上端用螺钉连接空心的压盖,阀杆外套有空心的波浪形的蛇形皮管,蛇形皮管一端翻边被压盖与阀盖之间压住、另一端用皮管卡卡住。由于蛇形皮管在阀杆带动下,只能作压缩运动,同时有效分隔开输送介质与阀杆接触,故有着较好的密封效果。
由于采用上述技术方案,与现有技术相比,结构紧凑,容易制作,使用寿命长,密封性好,防腐蚀等特点。
下面结合附图对本实用新型进一步说明。
附图是本实用新型剖视结构示意图。

如附图所示,阀座1中间有阀杆4和手轮5,阀座1上端连有阀盖3和压盖7,阀杆4外套有蛇形皮管2,蛇形皮管2-端被压盖7与阀盖3之间压住,另一端被皮管卡6卡住。
