Standard full height electric butterfly 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 the electric butterfly valve shall be determined separately. Since there are many kinds of electric butterfly valves, correct selection is very important. Therefore, in the overall design of the pipeline system, the design of the pipeline direction and support system (including fixed pipe support, guided sliding pipe support, etc.) shall be fully considered, and the shape and configuration of the electric butterfly valve shall be comprehensively considered, so as to achieve safety, rationality Suitable and economical * best combination. The rectangular electric butterfly valve is a flexible element with the pipe as the core, which makes axial, transverse and angular compensation on the pipeline.
The axial type electric butterfly valve is used to reduce the self-excited phenomenon of the medium. There is no inner sleeve inside the product, which largely limits the radial electric butterfly valve, so it is generally only used to absorb the axial displacement of the electric butterfly valve (if a small amount of radial displacement is really required in the pipeline system, its diameter * large displacement can be stated when ordering): the horizontal displacement electric butterfly valve (large pull rod) mainly absorbs the horizontal displacement perpendicular to the electric butterfly valve, The small pull rod horizontal electric butterfly valve is suitable for absorbing lateral displacement, and can also absorb the combination of axial, angular and any three directions of displacement: hinged electric butterfly valve (also called angular electric butterfly valve).
It is used together with two or three electric butterfly valves (single electric butterfly valve has no compensation ability) to absorb the transverse deformation in the one-way plane. The universal hinge (angular) electric butterfly valve is used together with two or three electric butterfly valves to absorb the three-dimensional deformation.
