卡套截止阀 J91W

卡套截止阀:(又叫针型阀)是仪表测量管路系统中重要组成部分,主要有截止阀和球阀,其功用是作开启或切断管道通路用。

  卡套式仪表阀门具有安装拆卸方便、连接紧固、有利于防火、防爆和耐压能力高、密封性能良好等优点,是电站、炼油、化工装置和仪表测量管路中的一种先进连接方式的阀门。

  卡套截止阀的密封性良好,使用寿命长,即使密封面损坏后,也只需要更换易损零件,即可继续使用。

  安装时应使介质的流向与阀体上的箭头方向一致。

  1,卡套截止阀标准,,卡套截止阀具有安装拆卸方便,卡套截止阀连接紧固,卡套截止阀有利于防火,卡套截止阀防爆和耐压能力高。卡套截止阀密封性能良好等优点是电站、炼油、化工装置和仪表测量管路中的一种先进连接方式的阀门。卡套截止阀的密封性良好,卡套截止阀使用寿命长,卡套截止阀即使密封面损坏后,卡套截止阀也只需要更换易损零件,卡套截止阀即可继续使用。卡套截止阀安装时应使介质的流向与阀体上的箭头方向一致。卡套截止阀是一种可以精确调整的阀门用途较广比如火焰切割用的割距调整火焰温度的旋钮就是针型阀,仪表针型阀是仪表测量管路系统中重要组成部分,卡套截止阀主要有截止阀和球阀,卡套截止阀其功用是作开启或切断管道通路用。

  卡套截止阀结构的基础上自行设计的,是目前应用最普遍的新一代阀门。
