Abstract

一种暗杆刀型陶瓷闸阀,属于阀门领域,它的阀体上安装陶瓷密封圈,闸板与阀体间陶瓷密封,在闸板与阀座相接触的密封面设有陶瓷板。本实用新型的优点和积极效果是:由于闸板为整体陶瓷结构,增加了闸板的耐腐蚀性,延长了闸板的使用寿命;同时,阀体上安装陶瓷密封圈做为阀座,陶瓷密封圈更耐腐蚀,耐磨损,使密封效果更好。

Description

暗杆刀型陶瓷闸阀
技术领域
本实用新型属于阀门领域,特别涉及一种暗杆刀型陶瓷闸阀。 
背景技术
现有的暗杆闸阀的密封主要是在闸板与阀座间的密封副,现有的密封副有更硬密封副和软密封副,硬密封副是在阀座流体的进口、出口处用金属材料进行镶嵌或堆焊而成,这种密封在煤渣、灰渣和渣水混合物的介质中使用,不抗击冲刷,不耐磨损,其密封面容易损坏,修复难度大,不便于更换和维修;另外,金属材料制成的硬密封副的热胀冷缩系数较大,遇到较热流体时,闸板和硬密封副会同时膨胀,造成闸板卡死在阀座内,开启困难,遇到温度较低的流体时,闸板和硬质密封副会同时冷缩,导致闸板和阀座之间产生间隙,造成流体的泄露。 
软密封副是由橡胶材料包覆在闸板的外面,橡胶材料不耐腐蚀,不耐磨损,在闸板开、关时,经常上下移动摩擦,容易使橡胶层磨损老化、脱落,在高温流体或管道内压力增大时,由于承受不了增大的压力,容易损坏,造成流体的泄漏。 
实用新型内容
本实用新型的目的在于克服上述的缺陷,提供一种暗杆刀型陶瓷闸阀,它通过采用陶瓷密封,因陶瓷材料具有抗击冲刷,耐腐蚀和耐磨损,提高阀门的使用寿命,减少了阀门的维修,提高了生产效率。 
本实用新型的目的是通过以下技术方案实现的:一种暗杆刀型陶瓷闸阀,它包括阀座、闸板、阀杆和手轮,在阀体的内部设有流体进口和流体出口,在流体进口和流体出口之间设置有闸板,在闸板的上端连接阀杆,阀杆的上端设置手轮,在阀体的内部设有阀座,其特征在于:所说的闸板为整体陶瓷结构,所说的阀座为陶瓷密封圈,闸板与阀座相接触的密封面设有陶瓷板。 
本实用新型的优点和积极效果是:由于阀门的闸板与阀体接触的密封面设有陶瓷结构密封圈的阀座,利用陶瓷材料具有抗击冲刷,耐腐蚀,耐磨损,提高了阀门的密封效果,延长了阀门的使用寿命,减少了阀门的维修成本,提高了生产效率。

图2是本实用新型局部剖视图。 
其中:1-阀座,2-闸板,3-阀杆,4-手轮,5-阀体,6-陶瓷板。 
具体实施方式
实施例:一种暗杆刀型陶瓷闸阀,它包括阀座1、闸板2、阀杆3和手轮4,在阀体5的内部设有流体进口和流体出口,在流体进口和流体出口之间设置有闸板2,闸板2为整体陶瓷结构,在闸板2的上端连接阀杆3,阀杆3的上端设置手轮4,在阀体5的内部设有阀座1,阀座1为陶瓷密封圈,阀体5与闸板2间陶瓷密封,闸板2与阀座1相接触的密封面设有陶瓷板6。
