The protection effect of double flange electric ball valve on the pipeline The double flange electric ball valve is a new product for the connection of pumps, valves and other equipment with the pipeline. They are connected by full bolts to make them 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 whole pipeline during operation. This not only improves the working efficiency, but also protects the pumps, valves and other equipment.
The double flange electric ball valve is mainly used in the pipeline system. Long distance pipeline is used for ground settlement, as well as some irresistible factors in the construction, which makes it difficult to ensure the axial concentricity of the pipeline. The installation of electric ball valve in the pipeline system can avoid compression or stretching where the axial thrust of the pipeline has a deviation from the axial concentricity of the pipeline, To avoid leakage and cracking of the pipeline, the damage of stress to the pipeline is reduced to ensure the smoothness of the pipeline, and the electric ball valve has the function of compensating the axial displacement of the pipeline. By adjusting the movable nut on the electric ball valve, the length between the electric ball valve body and the electric ball valve casing body can be adjusted to achieve compensation, During the final installation of the pipeline crane, the length of the electric ball valve shall be shortened first to facilitate the lifting. After reaching the position, the length of the electric ball valve shall be extended to facilitate the installation, connection and fixation of the pipelines at both ends. In the installation of the valve, the electric ball valve shall be installed to effectively protect the valve from the damage of the axial pressure of the pipeline itself, and ensure the convenient installation, disassembly and maintenance of the valve.
