Sealing function of flange electric ball valve in chemical electric ball valve Medium point flange electric ball valve plays a connecting role in electric ball valve, is one of the indispensable equipment in China's water purification and sewage industry, and plays an indispensable role in the entire sewage link. Because of this, the electric ball valve is developing rapidly in the water purification industry.
China is not only a big agricultural country, but also a big mechanical country. Every town has a variety of factories. The sewage discharged from factories should be discharged reasonably, without causing pollution hazards to villages and people. Flange electric ball valve is mainly used for connection of pump, valve and other accessories. Flange electric ball valve is composed of electric ball valve, short pipe flange, force transmission screw and other components, which can transmit the pressure thrust (blind plate force) of the connected parts and compensate the pipeline error, and cannot absorb the axial displacement. It is important to connect pumps, valves, pipelines and other accessories.
In the high-temperature and high-pressure electric ball valve, the sealing material used for the flange electric ball valve is that the valve sealing ring is easy to leak, and the valve sealing ring is easy to deform when it receives high temperature, generating irreversible plastic deformation. So how to use the flange electric ball valve in the chemical electric ball valve, especially the electric ball valve medium is high-temperature corrosive medium. The graphite packing seal ring developed by the designers of Tianzhu Electric Ball Valve Equipment Factory based on years of experience has a very good sealing effect. When the flange electric ball valve is manufactured, it is made of high-quality anti-corrosion materials. The seal ring is made of flexible graphite packing with anti-corrosion paint, which provides triple protection for the electric ball valve to effectively achieve corrosion resistance. Flange electric ball valve is mainly used in petrochemical electric ball valve, desulfurization and denitrification electric ball valve, seawater desalination electric ball valve and acid-base delivery electric ball valve.
