Select a suitable pump valve to connect the electric ball valve. The composition of the electric ball valve to connect the pump valve is: the electric ball valve is composed of the flange electric ball valve, the stub flange, the power transmission screw and other components, which can reduce the pressure thrust (blind plate force) of the connected parts and compensate for the installation error of the pipeline. The double flange electric ball valve cannot absorb the axial displacement. Double flange power connection is mainly used for connection of pump, valve and other accessories.
Instructions for installation and use of electric ball valve: A. Loosen the middle gland nut to make the sealing ring almost inoperable, and then adjust the short pipe, and adjust the size by 1/2 Δ L is the best, then adjust the joint, remove the first nut of the stud, make the pipe go through the center, and make the head of the stud align with the pipe flange hole, then one end can be installed. B. The nuts shall be pressurized symmetrically and tightened gradually. C. Install the flange at the other end by analogy. D. Compress the gland nuts symmetrically and gradually to fit. E. When working, if it is found that the local sealing is not tight, the gland nut can be pressed locally until there is no leakage. If the sealing at both ends is not tight, gradually tighten the nuts at both ends of the flange until there is no leakage.
