Standard full height pneumatic ball valve is applicable to all flue ducts. Due to various constraints, it is quite complex, but any complex pipeline system can select several fixed supports and different settings at different parts, and divide them into several relatively simple single pipe sections, "Z" type pipe sections and "Π" type pipe sections,
The deformation of each pipe section and pneumatic ball valve shall be determined separately. Due to the wide variety of pneumatic ball valves, correct selection is very important. Therefore, in the overall design of the pipeline system, full consideration shall be given to the design of the pipeline direction and support system (including fixed pipe support, guided sliding pipe support, etc.), and comprehensive consideration shall be given to the shape and configuration of the pneumatic ball valve to ensure safety, rationality Suitable and economical * best combination. The rectangular pneumatic ball valve is a flexible element with the pipe as the core, which makes axial, transverse and angular compensation on the pipeline.
The axial pneumatic ball valve is designed to reduce the self-excited phenomenon of the medium. There is no inner sleeve inside the product, which largely limits the radial pneumatic ball valve, so it is generally only used to absorb or pneumatic ball valve axial displacement (if a small amount of radial displacement is really required in the pipeline system, its diameter * large displacement can be stated when ordering): the transverse displacement pneumatic ball valve (large pull rod) mainly absorbs the transverse displacement perpendicular to the pneumatic ball valve, The small pull rod horizontal position pneumatic ball valve is suitable for absorbing lateral displacement, and can also absorb the combination of axial, angular and any three directions of displacement: hinged pneumatic ball valve (also called angular pneumatic ball valve).
It is used in combination with two or three pneumatic ball valves (single pneumatic ball valve has no compensation capacity) to absorb the transverse deformation in the one-way plane. The universal hinge (angular) pneumatic ball valve is used in combination with two or three pneumatic ball valves to absorb the three-dimensional deformation.
