At present, there is a popular butterfly valve shock absorber on the market. It completely hides the butterfly valve inside the shell, and the state of the butterfly valve cannot be seen directly outside, which is a bit incorrect! Therefore, if the butterfly valve is seriously rusted after a period of time, the manager cannot detect and replace it in time, which may lead to the terrible consequences of butterfly valve breaking, water pump sinking and pipeline breaking. Although the price of this kind of butterfly valve shock absorber is slightly lower, it should not be used as far as possible.
The butterfly valve damper is mainly used for anti vibration of pipelines and equipment in nuclear power plants, thermal power plants, chemical plants, steel plants, etc. It is often used to control the vibration of pipeline system caused by fluid vibration excitation (such as fluid pulsation, two-phase flow, high-speed flow, wind vibration, etc.). Butterfly valve shock absorber can effectively control each frequency
Frequency of vibration and swing, but to a certain extent, limit the normal thermal displacement of the pipeline. The additional force generated by the butterfly valve damper on the pipeline shall be fully considered in the design.
