Description:

节流截止放空阀  FJ41H

简单介绍
节流截止放空阀产品用途节流截止放空阀广泛应用于石油、天然气、煤气、石油液化气及炼油、机场、化工、油气储运等的管道上作闭路装置.

节流截止放空阀的详细介绍
FJ41H型节流截止放空阀的资料:
节流截止放空阀产品特点
1、本阀是一种新型的节流、截止、放空产品,该阀门采用笼形迷军团节流,具有多级节流效果,节流效果明显、密封可靠、操作维护方便等特点
2、阀门采用双重密封(硬、软质密封)使密封可靠、硬质合金封面可以更耐气流冲刷、耐磨损,双重密封能做到在高压气体介质条件下的零泄漏。阀门使用寿命长
3、阀座的密封面采用锥度密封,有利于阀门自身清洗附在密封面上的脏物
4、阀门的阀瓣上设置了平衡孔,活塞式密封,保证了启/闭全压差条件下稳定操作,开启轻便灵活、启闭扭矩小
5、节流截止放空阀和双作用式节流阀同时具有节流与截止(密封为零泄漏)作用节流部位与密封面分开,以减小气流对密封的冲刷
6、双作用式节流截止阀还具有多级节流功能,节流压差大,能适用于高压下的节流与截止
7、填料采用带自密封能力的V形填料结构,无需调节,开、关极为轻便。填料函处设有辅助密封油脂注入结构,使阀门填料密封性能可靠
8、本阀门可以进行在线维修,管线可以带压状态下更换填料等一系列易损件
9、本阀在阀门的底部设置了较大的排污孔,必要时要以打开,清理阀内污物
