Abstract

本实用新型公开了一种可锁式软密封闸阀,主要由阀体1、闸板2、阀杆7、阀盖6组成,其特征在于,阀杆7的顶部圆面上设有一偏心柱11,在阀盖6的顶部设有防护盖10。通过以上设置,本实用新型用特制专用钥匙方能开启,完全控制了介质的流失,该闸阀采用全封闭技术,减少了各部零件锈蚀。可广泛应用于阀门制造领域。

Description

可锁式软密封闸阀
技术领域
本实用新型涉及一种闸阀,确切地说是一种可锁式软密封闸阀。
背景技术
目前,我国自来水行业及其他管道输送业,经常为用户的欠费使用介质无法控制而深感头疼。原有的闸阀,上部零件多结构复杂,浪费原材料;闸阀头部,不管是外露的还是内藏的,都很容易开启;阀体与上盖联接螺栓为外漏式,容易锈蚀。
发明内容
本实用新型的目的便是提供一种防锈蚀,可有效控制介质的可锁式软密封闸阀。
本实用新型主要由阀体、闸板、阀杆、阀盖组成,阀盖与阀体由螺栓固定连接,阀杆设在阀盖中,闸板与螺母连接,螺母旋合在阀杆上,其特征在于,阀杆的顶部圆面上设有一偏心柱,在阀盖的顶部设有防护盖。所述偏心柱为一圆柱形钢柱,其圆柱面与阀杆顶部的圆柱面相切。
通过以上设置,本实用新型阀杆的顶部设有偏心柱,深藏于阀盖中,用特制专用钥匙方能开启,完全控制了介质的流失;该闸阀采用全封闭技术,减少了各部零件锈蚀;该闸阀上盖部分,零件少,产品结构简单,体积小,节约原材料。

具体实施方式
如图1所示,可锁式软密封闸阀,主要由阀体1、闸板2、阀杆7、阀盖6组成,阀盖6与阀体1由螺栓固定连接,;两者中间设有方密封垫4,阀杆7设在阀盖6中,闸板2与螺母5连接,螺母5旋合在阀杆7上,转动阀杆7可使闸板2随阀杆7上升或下降实现开关功能,阀杆7的顶部圆面上设有一偏心柱11,如图2所示,所述偏心柱11为一圆柱形钢柱,其圆柱面与阀杆7顶部的圆柱面相切,此种设置可确保没有特定的开启工具,闸阀是不会被开关的,可有效控制介质的流失;在阀盖6的顶部设有防护盖10,对整个阀体实现了封闭,减少了零件的锈蚀。
