The torque calculation of the ball valve gear box involves multiple physical quantities and parameters, mainly including valve diameter, valve pressure, friction coefficient, and valve axis diameter. First of all, the torque of the valve is the torque required to open and close the valve, which can be calculated by formulas. The specific calculation formula is: the valve diameter (area) is multiplied by the valve pressure to obtain the static pressure on the valve bearings, and then multiplied by the friction coefficient. Finally, the diameter of the valve axis was divided by 1000 to obtain the torque of the valve. This calculation is based on valve diameter, valve work pressure, and friction coefficient. The friction coefficient depends on the valve materials and working environment. For example, if steel is used as a valve material, the friction coefficient between the steel or steel and the rubber is 0.1 and 0.15, respectively. This calculation result is a theoretical value, which can be used as a reference for actual design and application.
