How to adjust the range of ball valve damper in hot state
When it comes to the use of ball valve damper, it is quite extensive, including the anti vibration of pipes and equipment used in nuclear power plants, thermal power plants, chemical plants, steel plants, etc. It is often used to control fluid vibration excitation (such as fluid pulsation, two-phase flow, high speed flow and aeolian vibration) of pipeline system. Ball valve damper is a vibration control installation with flexible response to displacement.
How is the hot adjustment range of ball valve damper?
1. The shock absorber of ball valve shall firmly shrink all possible loose conditioning parts;
2. When stopping the hot adjustment of the ball valve damper, it is necessary to ensure that the remaining stroke after the ball valve is tightened is greater than the axial displacement of the damping ball valve caused by the pipe cold shrinkage displacement;
3. After inspection and adjustment of supports and hangers;
4. It is not suitable to condition parts by destroying threads or spot welding.
5. During load troubleshooting, a series of inspection and troubleshooting will be stopped after the manufacturing of supports and hangers is completed; 6. If the reason why the load displacement indication does not coincide with the hot state mark when operating at rated temperature is removed, the load displacement indication can not be accurately adjusted to the hot state position mark, and the pointer has been quite close to the hot state position mark, and the support and hanger have not moved to the end of their travel range, then the support and hanger can be considered normal.
