The pipeline electric butterfly valve is composed of arc concave convex elastic pad and arc metal plate, which are pasted locally. It is usually used on the pipeline of mechanical equipment with elastic support. It not only plays the role of elastic support for the pipeline, isolation of pipeline through the wall, etc., but also has the role of good isolation of pipeline mechanical vibration and significant reduction of structural noise, In order to improve the environment and increase the applicable life of equipment, the pipeline seismic support and hanger system layout principle can fully protect the electromechanical systems in the earthquake, and can be used to resist the damage from horizontal and vertical seismic forces
The layout principle of the pipeline seismic system (1) The lateral spacing requirements for the reinforcement of seismic supports and hangers are as follows: for pipelines made of rigid materials such as grooved connecting pipes, welded steel pipes, brazed copper pipes, the horizontal hanger spacing shall not exceed 12m; For pipelines made of non rigid materials such as HDPE, the spacing between horizontal hangers 17 shall not exceed 6m (2) The longitudinal spacing requirements for the reinforcement of seismic supports and hangers are as follows: for pipelines made of rigid materials such as grooved connecting pipes, welded steel pipes, brazed copper pipes, the longitudinal spacing of hangers shall not exceed 24m; For pipelines made of non rigid materials such as HDPE, the horizontal hanger spacing shall not exceed 12m.
