Product Description

    Electric ball valve can realize remote control and on-site control. Choose the correct electric ball valve to prevent the torque from being too small to switch the electric ball valve. When choosing electric ball valve, please pay attention to: operating torque operating torque is the main parameter of selecting electric valve device. The torque should be 1.2 to 1.5 times the valve operating torque. There are two main structures for operating thrust electric valve devices: one is not equipped with a thrust plate and directly outputs torque; the other is equipped with a thrust plate, and the output torque is converted into output thrust through the stem nut in the thrust plate. Number of turns of output shaft The number of turns of output shaft of an electric valve device is related to the nominal diameter of the valve, the pitch of the valve stem, and the number of thread heads. It should be calculated as M=H/ZS (M is the total rotation circle that the electric device should meet Number, H is the opening height of the valve, S is the thread pitch of the valve stem drive, Z is the number of stem thread heads). Stem diameter For multi-turn rising stem valves, if the diameter of the stem allowed by the electric device cannot pass through the stem of the matched valve, it cannot be assembled into an electric valve. Therefore, the inner diameter of the hollow output shaft of the electric device must be larger than the outer diameter of the stem of the rising stem valve. For part-turn valves and dark-stem valves in multi-turn valves, although the passage of the stem diameter does not need to be considered, the stem diameter and the size of the keyway should be fully considered when selecting and matching, so that it can work normally after assembly. If the opening and closing speed of the output speed valve is too fast, water hammer is likely to occur. Therefore, the appropriate opening and closing speed should be selected according to different conditions of use.
