Description

一种新型的闸阀
 技术领域：
    本发明涉及阀门技术领域，尤其涉及一种新型的闸阀。
背景技术：
    闸阀的启闭件是闸板，闸板的运动方向与流体方向相垂直，闸阀只能作全开和全关，不能作调节和节流，闸板有两个密封面，最常用的模式闸板阀的两个密封面形成楔形，楔形角随阀门参数而异，闸阀驱动方式分为手动闸阀、气动闸阀、电动闸阀，最常选用气动或者电动两种自动控制方式，闸阀的结构分类有多种不同的方式，其主要区别是所采用的密封元件结构形式不同，根据密封元件的结构，常常把闸阀分为几种不同的类型，而最常见的形式是平行式闸阀和契式在闸阀，根据阀杆的结构，还可分为明杆闸阀和暗杆闸阀；现有的闸阀由于其结构的原因，闸板的行程较长，对气动或者电动装置的扭矩要求大，动作周期较长，使用不够灵活。
发明内容：
本发明的目的是提供一种新型的闸阀，它结构简单，使用方便，操作灵活，密封效果好，能使密封闸板圆周均匀承受物料的冲击和磨损，避免了闸板在长期运行过程中局部损坏或磨穿，使其寿命大大延长。
为了解决背景技术所存在的问题，本发明是采用以下技术方案：它是由主阀体1、副阀体2、阀杆3、阀板支承架4、闸板5、碟簧6组成；主阀体1的两侧分别设置有副阀体2，主阀体1的中部设置有阀杆3，阀杆3的下端设置有闸板5，阀杆3与闸板5的连接处设置有阀板支承架4，阀板支承架4的下端设置有碟簧6。
所述的闸板5采用合金钢材质制成，适用于耐腐蚀和耐磨损的工况。
本发明采用双闸板设计，由两块闸板来切断物料，双闸板在弹簧静压下能保证两面密封不渗漏，当闸板5的一面有压力时，另一面通过碟簧6的作用能和密封座更紧密的接触，以达到密封的效果，适合于在全开或全关的状态下工作，如果闸板5长期处于半开关的状态下工作，闸板5的密封面会因受介质冲刷而变得不严密。
本发明结构简单，使用方便，操作灵活，密封效果好，能使密封闸板圆周均匀承受物料的冲击和磨损，避免了闸板在长期运行过程中局部损坏或磨穿，使其寿命大大延长。
附图说明：
图1是本发明的结构示意图；
图2是图1的A部放大图。
具体实施方式：
参照图1，图2，本具体实施方式采用以下技术方案：它是由主阀体1、副阀体2、阀杆3、阀板支承架4、闸板5、碟簧6组成；主阀体1的两侧分别设置有副阀体2，主阀体1的中部设置有阀杆3，阀杆3的下端设置有闸板5，阀杆3与闸板5的连接处设置有阀板支承架4，阀板支承架4的下端设置有碟簧6。
所述的闸板5采用合金钢材质制成，适用于耐腐蚀和耐磨损的工况。
本具体实施方式采用双闸板设计，由两块闸板来切断物料，双闸板在弹簧静压下能保证两面密封不渗漏，当闸板5的一面有压力时，另一面通过碟簧6的作用能和密封座更紧密的接触，以达到密封的效果，适合于在全开或全关的状态下工作，如果闸板5长期处于半开关的状态下工作，闸板5的密封面会因受介质冲刷而变得不严密。
本具体实施方式结构简单，使用方便，操作灵活，密封效果好，能使密封闸板圆周均匀承受物料的冲击和磨损，避免了闸板在长期运行过程中局部损坏或磨穿，使其寿命大大延长。
