The pneumatic ball valve is mainly used in the pipeline system. The long-distance pipeline is used for ground settlement, and some irresistible factors in the construction make it difficult to ensure the axial concentricity of the pipeline. The installation of pneumatic ball valves in the pipeline system can avoid 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 pneumatic ball valve has the function of compensating the axial displacement of the pipeline. By adjusting the movable nut on the pneumatic ball valve, the length between the pneumatic ball valve body and the pneumatic ball valve casing body can be adjusted to achieve compensation, Shorten the length of the pneumatic ball valve in the final installation of the pipeline crane to facilitate lifting. When the length of the pneumatic ball valve reaches the position, it is convenient to install, connect and fix the pipelines at both ends. The pneumatic ball valve is added in the valve installation 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 pneumatic ball valve is also called the detachable double flange loose sleeve power transmission compensation joint. The double flange pneumatic ball valve is composed of flange loose sleeve pneumatic 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 pneumatic 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 pneumatic ball valve is composed of loose sleeve pneumatic 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. Pneumatic ball valve is used with valves: pneumatic ball valve is mainly used with valve disassembly, especially the installation and disassembly of large diameter valves, which is very convenient for installation, disassembly and maintenance. When lifting valves, the pneumatic ball valve can shrink the fastening bolts to make the distance between pipelines larger. After lifting the valve, adjust the length of the pneumatic ball valve, and tighten the bolts to fix the valve. During operation, the pneumatic ball valve has a good protection effect on the valve, especially in case of displacement and subsidence of long-distance pipeline, the pneumatic ball valve can absorb and compensate these displacements, so that the pipeline connected by flanges will not leak.
