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。
针型阀具有安装拆卸方便、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***连接方式的阀门。针型阀的密封性良好，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。安装针型阀时应使介质的流向与阀体上的箭头方向一致。手动截止阀、球阀可安装在管路的任何位置上。针型阀是一种可以***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，主要有截止阀和球阀，其功用是作开启或切断管道通路用。任何阀门的作用都是为了切断流体. 根据阀芯的不同,可以分为截止阀,闸板阀,旋塞阀,球阀,碟形阀,针型阀等等. 针型阀的阀芯就是一个很尖的圆锥体,好象针一样插入阀座,由此得名. 针型阀形比其他类型的阀门能够耐受更大的压力,密封性能好,所以一般用于较小流量,较高压力的气体或者液体介质的密封.针型阀形与压力表配合使用是***合适的了.一般的针型阀形都做成螺纹连接。
