: 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。 Needle valve : It is an important part of the instrument measuring pipeline system. It mainly includes globe valve and ball valve. Its function is to open or cut off the pipeline path. Needle valve has the advantages of convenient installation and disassembly, fast connection, good fire resistance, high explosion resistance and high pressure resistance, and good sealing performance. It is an advanced connection valve in power stations, oil refining, chemical installations and instrumentation pipeline . Needle valve has good sealing performance and long service life. Even if the sealing surface is damaged, only the wearing parts need to be replaced, and it can continue to be used. When installing the needle valve, the flow direction of the medium should be consistent with the direction of the arrow on the valve body. Manual stop valve and ball valve can be installed in any position of the pipeline. Needle valve is a valve that can be precisely adjusted for a wide range of uses, such as the cutting distance for flame cutting, the knob for adjusting the flame temperature is a needle valve, and the instrument needle valve is an important part of the instrument measurement pipeline system. Stop valve and ball valve are used to open or cut off the pipeline path. . 根据阀芯的不同 , 可以分为截止阀 , 闸阀 , 旋塞阀 , 球阀 , 蝶阀 , 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最合适的了 . 一般的针型阀形都做成螺纹连接。 The function of any valve is to cut off the fluid . Depending on the valve core , it can be divided into stop valve , gate valve , plug valve , ball valve , butterfly valve , needle valve and so on . The valve core of a needle valve is a very sharp cone It seems to be inserted into the valve seat like a needle , hence the name . Needle valve shape can withstand greater pressure and better sealing performance than other types of valves , so it is generally used for small flow , higher pressure gas or liquid Medium seal . Needle valve shape and pressure gauge are the most suitable for use . The general needle valve shape is made of thread connection.
