【技术实现步骤摘要】
本技术涉及一种截止阀,尤其涉及一种氯气专用截止阀。
技术介绍
目前现有的氯气专用截止阀包括阀体、阀盖、阀瓣、阀杆、填料箱,其中阀体上设有进气口和出气口,进气口和出气口之间通过气流通道口连通,阀体和阀盖均设有安装阀杆的内腔,阀杆滑动安装在阀体内腔并穿过阀盖内腔,阀杆的端部安装有与所述气流通道口密封配合开闭所述截止阀的阀瓣,使用过程中,阀杆往复运动从而带动阀瓣运动,也就实现阀瓣与气流通道口密封配合关闭截止阀,或者阀瓣与气流通道口分离开启截止阀,而目前普通的阀门密封性能差、易泄漏,阀杆外周与其相接触的各部件之间的间隙成为主要泄流处,也因此阀杆的外周与其相接触的各部件之间的密封成为截止阀密封最大的难题。
