Structural principle of stainless steel ferrule joint

The structural principle of stainless steel ferrule joint is a small valve used to control micro-adjustment. Its general diameter is 15 mm and 10 mm. The seal is formed by the tight fit of the tapered thread valve body and the valve seat sealing ring. The material used for needle valves is generally composed of alloy steel, but there are also valve head sealing rings made of copper alloys. so. Before using the needle valve. The material of the valve head and valve seat should be disassembled and inspected. To prevent U-turn or wear during use. In the fermentation production process, stainless steel needle valve is used more, which plays a certain role in ensuring the tightness. Good cutting performance of the ferrule type joint. One of the biggest features is that the contact between the spherical valve core and the inclined surface of the valve seat is in the form of line contact, which reduces the contact surface and further reduces the leakage rate of the valve.
