There are two types of mainframe structures for Anhui pneumatic ball valves: one is not equipped with a thrust disc, which can directly output torque; the other is that the thrust disc needs to be configured, and the output torque also needs to pass through the valve stem in the thrust disc. The nut is converted to output thrust. Because the working characteristics and utilization rate of Anhui pneumatic ball valves are determined by the type of valve, the working specifications of the device and the position of the valve on the pipeline or equipment are also very important. Therefore, the selection of the appropriate Anhui pneumatic ball valve is essential to prevent the overload of the electric valve (operating torque is higher than the control torque). He believes that the school not only teaches students the skills, but also instills the corresponding values into the students. "We now educate everyone to like to pursue the trend. What professional trends and fashions are all open at this time.

Anhui pneumatic ball valve

Pneumatic flanged three-way ball valve

Selection of pneumatic ball valve For a simple one-way valve with simple structure, it is necessary to pay attention to the reasonable selection of its opening pressure: when the opening pressure is low, the resistance loss when the liquid flows through the ball valve can be reduced; however, if it is only used as back pressure For the check valve used in the valve, its opening pressure is very high, because this is the only way to ensure sufficient back pressure and reduce the high energy consumption of the hydraulic system.

When the rated pressure and the rated flow rate are both lower than the use pressure and the use flow rate, it is easy to cause the hydraulic pressure to be stuck, the power is in a problem, and the absolute impact on the working quality of the ball valve; therefore, the sequence valve and the reduction installed in the system The flow rate of the pressure valve should not be much smaller than the rated flow rate, otherwise it will cause disorder in the system. In terms of adjustment function, the equal percentage characteristic is optimal, and the adjustment is not disordered, and the adjustment function is good.
