The protection effect of double flange pneumatic ball valve on the pipeline Double flange pneumatic 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 pneumatic ball valve is mainly used in the pipeline system. Long distance pipeline is used for ground settlement, as well as some irresistible factors in construction, which makes it difficult to ensure the axial concentricity of the pipeline. The addition of pneumatic 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 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. In the installation of the valve, the pneumatic ball valve is added 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.
