Daily maintenance and common maintenance of ball valves, Q347F-16C and Q41F-16C

Answer:

Filler and sealing materials pay attention to point, basically no technical things

Structural type code:Floating type: 1 means through flow, 2 indicates Y type three pass, 4 represents L type three pass, and 5 represents T type three pass;Fixed type: 0 represents the straight through of the hemisphere, the 6 represents the four channel, the 7 indicates the through flow, the 8 represents the L type three pass, and the 9 represents the Y type three pass;Sealing material: B Babbitt, fluorine rubber, F F46, H direct machining of fluorine lining, rubber lining, stainless steel J M Monel alloy, N nylon plastics, Monel P, Y alloy, W valve;Pressure rating code: 16 said the pressure of 16 kg (1.6Mpa) up to 64Mpa; 150LB said American Standard pound pressure, maximum pressure rating up to 2500LB (150LB=1.6MPA/300LB=2.5-4.0mpa/400LB=6.4mpa/600LB=10mpa); 5K said on stage pressure, the maximum pressure of 63K;Body material: A titanium and titanium alloy, C steel, I stainless steel, chrome molybdenum steel, P18-8 stainless steel, S plastic, RMo2Ti.

Q347F-16C is a worm fixed ball valve, and Q41F-16C is a manual flanged ball valveBall valve model preparation methods and instructions:Ball valve additional code: V means that the spool with V structure, D means low temperature, B means insulation, P stands for eccentric structure, U and S and DY, more said upload type;Ball valve Name: Q means ball valve;Ball valve drive Code: 2, said electro hydraulic, 3, said the turbine, 6 pneumatic, and 7 that liquid, and 9 that electric, manual no code;Connection mode code: 1 for internal thread, 4 for flange type, 6 for welding, and 7 for clamp type;
