一种高速开启阀及开启方法
本专利技术涉及一种高速开启阀及开启方法,属于阀门
,尤其适用于煤矿瓦斯爆炸后的灭火装置开启。
技术介绍
通常来说,管路或者容器出口安装的阀门希望具有快速的响应性,以煤矿使用的灭火装置为例,一旦煤矿出现瓦斯爆炸,则希望煤矿中的灭火装置能够快速开启将火势控制。现有煤矿的灭火装置多是在出口位置安装球阀组件,球阀在开启时主要是利用阀芯的转动,一般需要阀芯转动90度或180度才能将阀门开启,释放存储在灭火装置内的灭火剂,但是,阀芯转动开启的过程中需要的时间较长,并且,由于灭火装置内的压力较高,为了能够实现有效可靠的密封,需要体积和重量较大的阀体才可完成,由此增加了阀芯开启时的阻力,使得现有的阀门在开启速度上难以满足使用要求,因此,如何提高阀门的开启速度,改善阀门的响应性成为亟需解决的问题。
技术实现思路
为解决以上技术上的不足,本专利技术提供了一种高速开启阀及开启方法,利用锁杆的直线移动实现阀门的开启,可实现阀门毫秒级的开启速度。本专利技术的技术方案如下:一种高速开启阀,包括阀体,所述阀体内设置有交叉的排放通道和移动通道,所述排放通道与外界连通, ...
