At present, there is a popular electric butterfly valve on the market. It hides the butterfly valve completely 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 electric butterfly valve is slightly lower, try not to use it.
The electric butterfly valve 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.). The electric butterfly valve 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 electric butterfly valve of the butterfly valve on the pipeline shall be fully considered in the design.
