Flange valve opening and closing is plug valve, sealing surfaces appear flat or cone, disc make linear movement along the centerline of the fluid, the flange as the structure of the valve body has a straight-through, straight and right Angle type. Flange globe Industrial Valves flange globe valve working principle: subject to compulsory sealed valve, the valve is closed, must be pressure on the disc, to force a sealing surface does not leak. When medium by disc below into the valve 6, the operating force needed to overcome the resistance, is stem and packing of the friction force and the thrust produced by medium pressure, close the Industrial Valves strength is stronger than open the valve, so it's bigger, the diameter of the stem or stem top bending failure happens. The structure characteristics of the valve flange: 1. flange structure is compact, aesthetically pleasing, excellent performance. Disc and stem adopts loose connection structure, flexible for opening and closing, the valve stem design the sealing pair, improve the service life of the valve and seal performance. 2. Flange globe valve seal materials reasonable matching, disc in operation with the seat of the friction force is small, long service life. 3. Flange globe valve stem nitriding treatment on the surface, with good corrosion resistance, frictional resistance. With four fluorine packing material, reliable seal, flexible operation, opening and closing torque is small. 4. Flange globe valve can choose all kinds of standard piping flange and flange sealing surface pattern, also can choose manual, worm gear, electric, pneumatic, hydraulic, etc all kinds of driving mode, satisfy different customers' needs. Flange globe valve USES: flange globe valve is suitable for the nominal pressure PN1. 6 ~ 16. 0 mpa, the working temperature 29 ~ 550 ℃ in the petroleum, chemical, pharmaceutical, chemical fertilizer, power industry, such as all kinds of working condition of pipeline, cut off or connect medium. Applicable medium: water, oil, steam, acid medium, etc. Operation mode: manual, gear drive, electric, pneumatic. Application scope of high pressure cast steel gate valve is suitable for the nominal pressure of 4 gb. 0 million ~ 10. 0 million mpa mpa conversion methods ( 1 million mpa = 10 kg) Negative 29 to six hundred degrees Celsius, the working temperature of petroleum, chemical, pharmaceutical, chemical fertilizer, power industry, such as the pipeline under various working conditions, cut off or connect pipe medium, can't adjust and throttling. Applicable medium: water, oil, steam, acid medium, etc.
