The electric ball valve is mainly used in the pipeline system. The electric ball valve is used for ground settlement in long-distance pipeline and some irresistible factors in construction, which make it difficult to ensure the axial concentricity of the pipeline. The installation of electric ball valve in the pipeline system can avoid the compression or stretching of the axial thrust of the pipeline where the axial concentricity of the pipeline deviates, 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, ensuring the installation, disassembly The removable double flange loose sleeve transmission compensation joint is convenient for maintenance.
The detachable double flange electric ball valve is also called the detachable double flange loose sleeve power transmission compensation joint. The double flange electric ball valve is composed of flange loose sleeve electric ball valve, short pipe flange, power transmission screw and other components, which can reduce the pressure thrust (blind plate force) of the connected parts and compensate 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 loose sleeve connection of pump, valve and other accessories. The double flange loose sleeve electric ball valve is composed of loose sleeve electric ball valve, short pipe flange, force transfer screw and other components. It can transfer the pressure thrust (blind plate force) of the connected parts and compensate for pipeline errors, and cannot absorb axial displacement. It is mainly used for loose sleeve connection of pump, valve, pipeline and other accessories. It is used as a loose sleeve connection device for pipes with seawater, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, product oil, air, gas, steam and hot gas whose temperature is not higher than 205 ℃ to absorb axial displacement and bear pressure and thrust within the allowable displacement range. Use of electric ball valve with valve: electric ball valve is mainly used with valve disassembly, especially the installation and disassembly of large diameter valve, which is very convenient for installation, disassembly and maintenance. When lifting the valve, the electric ball valve can be fully shrunk by fastening bolts, making the distance between pipelines larger. After lifting the valve, adjust the length of the electric ball valve, and tighten the bolts to fix the valve. During operation, the electric ball valve has a good protection effect on the valve, especially in case of displacement and subsidence of long-distance pipeline, the electric ball valve can absorb and compensate these displacements, so that the pipeline connected by flanges will not leak.
