1. Refers to different
1. Ballow valve: The valve is driven by the valve stem, and the valve of the rotation movement is used to rotate the valve axis.
2. Butterfly valve: also known as a flip valve, which is a simple regulatory valve. The butterfly valve controlled by the switch control can be used for the low -voltage pipeline medium refers to the closing part (valve or butterfly plate) Open and close a valve.
Different characteristics
1. Ball valve: The fluid resistance is small, and its resistance coefficient is equal to the pipe segment of the same length. Simple structure, small size, light weight. The cover material of the ball valve is widely used in the cover materials of the ball valve, and it has been widely used in vacuum systems. It is easy to operate and quickly and close. From full opening to full level, it only needs to rotate 90 ° to facilitate long -distance control.
2. Butterfly valve: The butterfly valve has the characteristics of simple structure, small volume, light weight, material consumption, small installation size, rapid switching, 90 ° to turn, small driving moment, etc. The medium has good fluid control characteristics and closed sealing performance.
Third, different use
1. Ballow valve: It can be used in the regulation and control of fluids. Among them, the hard seal V -type ball valve has a strong shear force between its V -type ball core and the metal valve seat of the stacked hard alloy. Solid material, etc. medium. The multi -passing valve can not only flexibly control the combination, diversion, and flow switching of the medium on the pipeline, but also shut down any channel to connect the other two channels.
2. Butterfly valve: valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays a role of cutting and throwing on the pipeline. The butterfly valve opening part is a disc -shaped butterfly board that rotates around its own axis in the valve body to achieve the purpose of opening or adjusting.
