Abstract

本实用新型提供一种带排渣槽的耐磨环，所要解决的问题是：矿业用阀种类繁多，大多用于矿浆输送、尾矿输送、矿床填充和污水排放等，阀门在上述用途的管道系统中作为开关和调节作用。由于工作介质和工作环境的影响，使阀门磨损的比较严重，工作介质的沉积会使闸板在进行关闭动作时受阻、卡死，无法完全闭合。本实用新型的技术要点是耐磨环底座上设置有一个矩形排渣槽，耐磨环底座的径向截面为L形；所述排渣槽下沿位于耐磨环底座上沿下方。本实用新型的优点是利用闸板下落时的压力将闸板轨道内的杂物排出，维持阀门原有的密封性，延长阀门的使用寿命。

Description

带排渣槽的耐磨环
技术领域
本实用新型涉及矿业阀密封技术领域，特别涉及一种带排渣槽的耐磨环。
背景技术
工业的发展带动了矿业领域的进步，矿业中原有的技术参数都进行了提升，对与矿业相关的阀门产业，虽然随着技术的革新有一定的提高，但是仍无法全面满足矿业用阀的需要。
矿业用阀种类繁多，大多用于矿浆输送、尾矿输送、矿床填充和污水排放等，阀门在上述用途的管道系统中作为开关和调节作用。由于工作介质和工作环境的影响，使阀门磨损的比较严重，工作介质的沉积会使闸板在进行关闭动作时受阻、卡死，无法完全闭合。
发明内容
本实用新型的目的是提供一种带排渣槽的耐磨环。
本实用新型的技术方案是：耐磨环底座上设置有一个矩形排渣槽，耐磨环底座的径向截面为L形；所述排渣槽下沿位于耐磨环底座上沿下方。
本实用新型的优点是：在阀门的闸板落下时，阀座内沉积的杂物通过排渣槽被推出阀座，不会影响闸板关闭。本实用新型还具有结构简单、操作简便、实用性强等特点。
附图说明
图1是本实用新型的结构示意图；
图2是图1 的A-A向剖视图；
图3是本实用新型的使用状态示意图。
下面将结合附图通过实例对实用新型作进一步详细说明，但下述的实例仅仅是本实用新型其中的例子而已，并不代表本实用新型所限定的权利保护范围，本实用新型的权利保护范围以权利要求为准。
具体实施方式
实施例1
参见图1~2，耐磨环底座1上设置有一个矩形排渣槽2，耐磨环底座的径向截面为L形；所述排渣槽下沿位于耐磨环底座上沿下方。
参见图3，闸板下落时将阀座内沉积的杂物通过排渣槽挤压出阀座4中间的闸板轨道，使闸板3在长时间使用之后，下落时仍能够维持原有的密封性，提高了阀门的使用寿命并延长了阀门的使用时间，节省了大量人力物力。

Claims (1)
