The ferrule needle valve is a valve that can be precisely adjusted for a wide range of applications, such as the cutting distance of flame cutting. The knob that adjusts the flame temperature is a ferrule needle valve. The instrument ferrule needle valve is an important part of the instrument measurement pipeline system, mainly including stop valve and ball valve, its function is to open or cut off the pipeline channel. The spool of the ferrule needle valve is a very pointed cone that inserts into the valve seat like a needle, hence the name.
Compared with other types of valves, the ferrule needle valve can withstand greater pressure and has good sealing performance, so it is generally used to seal gas or liquid media with small flow and high pressure. It is very suitable to use the ferrule needle valve with pressure gauge, and the general ferrule needle valve is made of threaded connection.
Anti-corrosion method of ferrule needle valve:
1. The main material of the valve body is stainless steel and carbon steel. The difficulty in valve body material selection is not only to consider corrosion, but also to consider factors such as pressure and temperature resistance, economical and reasonable, and easy to buy.
2. Take lining measures, such as lining with lead, lining with aluminum, lining with engineering plastics, lining with natural rubber and various synthetic rubbers. This is an economical approach if media conditions permit.
3. When the pressure and temperature are not high, the use of non-metals as the main material of the valve can often effectively prevent corrosion.
