Detailed description of the invention
This utility model below in conjunction with accompanying drawing with describe in detail.
A kind of fast-assembling butterfly valve, including valve body 9, butterfly plate 6, driving mechanism, described butterfly plate 6 is provided with centrage, and butterfly plate 6 is located upper and lower two ends at the center line and is provided with butterfly plate connecting shaft 602, and described butterfly plate 6, butterfly plate connecting shaft 602 are formed in one.Wherein, butterfly plate 6, butterfly plate connecting shaft 602 can pass through to be stamped and formed out, it is possible to by Standard Module Foundry Production.Butterfly plate, butterfly plate connecting shaft are integrated, it is not necessary to set preformed hole in butterfly plate main body in advance for installing valve rod, will not leave behind gap and cause leakage, it is also possible to occur that error causes that butterfly plate unbalance stress causes impaired when avoiding manually connecting butterfly plate and valve rod.
Described butterfly plate 6 outer shroud place thickness is less than butterfly plate 6 center thickness, and described butterfly plate 6 outer shroud place is inclined-plane.Butterfly plate main body so can be made in use to be subject to the impulsive force dispersion of fluid, it is prevented that butterfly plate is smashed under the excessive impulsive force of fluid.
Described butterfly plate 6 is arc-shaped transitional surface with butterfly plate connecting shaft 602 joining place so that medium is minimized through the flow resistance of butterfly plate, reaches energy-saving and cost-reducing purpose.
