Abstract

在截止阀原手轮上装入数块磁铁,并将其罩入非 磁性密封罩内与阀体密封为一个整体,再在罩外上部 装上一个磁性手轮,磁体手轮也装有数块磁铁,当旋 转手轮时,手轮磁铁对罩内磁体轮进行磁动作用。于 是带动阀杠向上,反之向下,从而达到了控制阀门的 开闭,并彻底解决了外泄漏问题。

Description

本实用新型涉及到一种截止阀制造的技术领域,是一种新型无外泄漏截止阀。
现有的截止阀启闭是通过手轮螺母作用在阀杆上,而阀杆是采用填料函封或波纹管和填料函组合密封。由于填料的磨损和波纹管理的破裂造成介质沿阀杆间隙向外漏液、漏气,严重时会影响管路及设备正常进行,甚至会造成火灾或爆炸等事故,因此常需频繁更换填料,不仅造成大量的浪费,而且又不能保证密封性。
本实用新型的目的是要提供一种新型磁能无外泄漏截止阀,它能有效地防止外泄漏现象。
本实用新型的目的是这样的:将现有阀门手轮改为磁体轮,磁体轮交叉排满了N-S极磁铁,其轮用非磁性密封罩与阀体密封成一个整体,以彻底隔离内介质。而后在磁体轮外(非磁性密封罩上部)装上磁体手轮,磁体手轮上也布满了N-S极交叉排列的磁铁块。当旋动磁体手轮时,磁体手轮上的磁铁对罩内的磁体轮进行同性相斥,异性相吸,于是磁体轮与磁体手轮同步旋转,带动阀杆螺母旋转,阀杆带动阀瓣向上或向下,从而达到了启闭阀门的效果,并彻底解决了外泄漏问题。
为了显示其启闭程度,在磁体手轮轴套上加工成蜗杆状,并与装在阀杆罩上的蜗轮配合形成开度指示器。当磁体手轮转动时,轴套(蜗杆)也随之转动并传动蜗轮,于是蜗轮刻度盘上所指的数字便是启闭程度。
本实用新型因为保留了原螺杆的传动机构,所以启闭力矩较小,可使用在中压系统中。
实用新型的具体结构由以下的实施例及其附图给出。
该无外泄漏截止上阀包括磁体手轮1,非磁性密封罩2,磁体轮3,磁铁块4,螺母5,阀杆6,骨架密封环7,阀瓣8,阀体9,10,开度指示器。
