Butterfly valve is a commonly used pipeline regulating valve, which consists of three parts: valve body, valve plate and transmission mechanism. It has the advantages of simple structure, light weight, convenient operation and good sealing performance, and is widely used in petrochemical, construction, water treatment and other industries. But some users will encounter such a problem: Can the butterfly valve be inverted? Let us answer this question below.
First, let's take a look at the structure of the butterfly valve. The butterfly valve adjusts the on-off and flow of the pipeline through the rotation of the valve plate. When the position of the valve plate in the valve body is in the closed state, the valve plate and the valve seat are tightly fitted, so as to realize the complete sealing of the pipeline; when the valve plate rotates at a certain angle, there will be a certain gap between the valve plate and the valve seat, This allows the medium to flow freely through the pipe.
Therefore, if the butterfly valve is inverted, the position of the valve plate will change. When the valve plate is located at the lower part of the valve body, the medium cannot flow normally. If it is used forcibly, it is easy to cause adverse consequences such as valve blockage and medium leakage. Therefore, under normal circumstances, we do not recommend flipping the butterfly valve.
Of course, in some special cases, we can also consider using the butterfly valve upside down. For example, under conditions such as high places or biogas, we need to keep the valve seat and sealing surface at a relatively high position. At this time, we can turn the butterfly valve upside down and process and modify it properly to ensure its normal operation. But this needs to consider the physical characteristics of the fluid and the actual engineering situation, and design and manufacture by professionals to ensure safety and reliability.
To sum up, butterfly valves are generally not recommended to be flipped, but in special cases, flipping can be considered. Full technical demonstration and design are required before inversion, and it must be operated and monitored by professionals. It is hoped that the majority of users and units can use the butterfly valve correctly to ensure the safe and effective operation of the project.
