阀的特点与作用：
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*。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，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zui合适 的了.一般的针型阀形都做成螺纹连接.

译文：
Needle valve type, is an important part of the meter in the piping system, mainly cut-off valve and ball valve, its function is used as open or cut off the pipeline path. Type needle valve with easy installation and disassembly, fastening connections, is conducive to fire, explosion, and the advantages of high compression capacity, sealed performance is good, is power stations, oil refining, chemical industry and instrument measuring line of an advanced connection mode of the valve. Needle valve sealing good, long service life, even if the sealing surface damage, also need to replace quick-wear part only, can continue to use. When installing type needle valve should make the flow of medium and the direction of arrow on valve body. Manual stop valve, ball valve can be installed in any position on line. Type needle valve is a valve can be precisely adjusted use widely, such as flame cutting with the cutting distance, the flame temperature adjustment knob is the needle valve, instrument type needle valve is an important part of the meter in the piping system, mainly cut-off valve and ball valve, its function is used as open or cut off the pipeline path. The effect of any valve for cutting fluid. Depending on the valve core, can be divided into cut-off valve, gate valve, plug valve, ball valve, the disc valve, needle valve, etc. Type needle valve valve core is a very sharp cone, like the needle inserted into the seat, hence the name. Type needle valve type than any other type of valve that can tolerate more pressure, sealed performance is good, so generally used for small flow, high pressure gas or liquid medium sealing. Type needle valve and pressure gauge is used the most appropriate. General type needle valve type screw thread connection.
