Overall specification of construction scheme for installation of single flange electric ball valve (1) Personnel: 1 person in charge of dewatering project, 1 technician and 8 construction workers. Generally speaking, the single flange electric ball valve is suitable for welding the pipeline while connecting with the flange. During installation, adjust the installation length between the two ends of the product and the pipe or flange. After installation and welding, tighten the gland bolts diagonally and evenly. The double flange electric ball valve consists of body, seal ring, gland, expansion spool and other main parts.
The double flange electric ball valve is applicable to the pipeline connected with flanges on both sides. During installation, adjust the installation length of the product's two ends and flanges, raise funds diagonally and tighten the gland bolts evenly to make it a whole with a certain displacement. The electric ball valve mainly relies on the angular displacement of the ball to absorb or compensate the lateral displacement of the pipeline in one or more directions, The pneumatic valve shall be used in pairs. A single spherical pneumatic valve has no compensation capacity and can be used as a pipe universal joint.
It is composed of electric ball valve, short pipe flange, force transmission screw and other components. It can transmit the pressure and thrust of the connected parts and compensate the pipeline error, and cannot absorb the axial displacement. The spherical electric ball valve mainly relies on the angular displacement of the ball to absorb or compensate the lateral displacement of the pipeline in one or more directions. The compensator should be used in pairs. A single spherical pneumatic valve has no compensation capacity and can be used as a pipe universal joint.
