How to adjust the range of electric butterfly valve in hot state
When it comes to the use of electric butterfly valves, they are quite extensive, including anti vibration of pipelines 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. Butterfly valve electric butterfly valve is a vibration control installation with flexible response to displacement.
How does the electric butterfly valve of butterfly valve adjust the range in hot state?
1. The electric butterfly valve of the butterfly valve should firmly shrink all possible loose conditioning parts;
2. The electric butterfly valve of the butterfly valve must ensure that the remaining stroke after the butterfly valve is tightened is greater than the axial displacement of the damping butterfly valve caused by the pipe cold shrinkage displacement when stopping the hot adjustment;
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.
