Description

一种耐磨闸阀
技术领域
本实用新型涉及一种闸阀,尤其提供一种涂有保护层的耐磨闸阀。
背景技术
闸阀一般由阀体、阀座、闸板、阀杆、传动机构组成,闸板采用对称连接在阀杆两侧的双闸板结构,其主要缺点是在磨损性介质工况使用时,闸板和阀座密封面磨损较严重,现有闸阀安装有耐磨环,降低了磨损程度,使之密封性能和使用寿命得到了增长。
实用新型内容
为了克服现有闸板和阀座密封面磨损较严重,本实用新型在现有基础上提供一种耐磨闸阀,不仅使磨损程度降到最小化,而且使用方便快捷。
本实用新型解决其上述技术问题所采用的技术方案是:一种耐磨闸阀,包括有阀体、阀座、手轮、阀杆、闸板和密封装置,手轮通过螺栓连接在阀杆上,所述的密封装置内安装有耐磨环,阀座连接在阀杆的另一端,所述的密封装置内设有用于防止磨损的保护层。所述的保护层是设在耐磨环与阀体接触面。所述的保护层为碳化钨涂层。
本实用新型的有益效果是:不仅更加有效的减少了闸阀的磨损,而且间接性的使闸阀的密封性和寿命的使用都得到了有效的提高。
附图说明
下面结合附图和实施案例进一步说明。
图1是本使用新型的结构示意图。
具体实施方式
如图1所示的一种耐磨闸阀,包括有阀体、阀座7、手轮2、阀杆3、闸板4和密封装置,手轮2通过螺栓1连接在阀杆3上,所述的密封装置内安装有耐磨环5,阀座7连接在阀杆3的另一端,所述的密封装置内设有用于防止磨损的保护层6,保护层6的作用在先有技术的基础上增加了一层保护结构,使闸阀本体磨损成度降到最低,所述的保护层是设在耐磨环5与阀体接触面,所述的保护层6为碳化钨涂层。本具体实施方式适用于闸阀(NZ40Y)。
