As a pipe connector, the electric ball valve can be used in the water supply pipeline system. The electric ball valve shall be of beam plate structure welded with steel plate and profile steel. The thickness of the panel shall not be less than 10 mm, and the welds shall be continuously welded. The surface of the ram shall be sand blasted to Sa2 (1/2) and coated with two coats of epoxy asphalt primer and finish respectively, with the total dry film thickness ≥ 250 μ m。 It shall have sufficient strength and rigidity under the maximum design water pressure.
Each stacked electric ball valve shall be equipped with a hanger matching the hook for lifting. The valve sealing plate around the electric ball valve shall correspond to the door frame seat, and the water stop at four sides shall be implemented. Each stacked electric ball valve shall be equipped with rollers for guiding and limiting to ensure safe and reliable operation. The electric ball valve is a new product connecting pumps, valves, pipelines and other equipment with pipelines. They are connected by bolts to make them become a whole with a certain displacement, so that they can be adjusted according to the on-site installation size during installation and maintenance, and the axial thrust can be transmitted to the entire pipeline system during work. This not only improves the working efficiency, but also plays a certain role in protecting pipeline equipment such as pumps and valves.
