Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind of three-flat ball valve, belongs to ball valve technical field.。
Background technique
Ball valve, its open-shut device is spheroid, and have manhole or passage by its axis, it is driven by valve rod, and rotates around the axis of valve rod, thus the effects such as the flow direction of medium are cut off, distribute and changed in realization.The main feature of ball valve is compact structure, and sealing is reliable, and structure is simple, easy to maintenance, and sealing surface and sphere are everlasting closed state, not easily by medium erosion, are easy to Operation and maintenance, so be widely used in many fields such as water, solvent, acid and rock gas.
Ball valve, as a kind of novel valve be widely used, its structure mainly contains the compositions such as valve body, spheroid, valve seat, valve rod, valve gap, filler, wherein spherome surface and valve seat interference fit are formed and seal, traditional valve body is divided into two-part, left valve barrel and right valve barrel, adopt resistant to elevated temperatures metal or nonmetallic material usually, and spheroid adopts stainless steel and relevant high temperature resistant material usually.Open or throttle down time, by lever drive rotating sphere, wear and tear gradually under the impact that spherome surface acts in frictional force etc.What no matter valve seal adopted is hard sealing or soft seal, because stainless steel metal or other metal surface affect by own material, processing and valve body material, design etc., make the increase of frictional force, in valve frequently opening and closing work, spheroid and valve base sealing place meeting continuous interference cause wearing and tearing, accelerate the speed of wearing and tearing, reduce the working life of valve, if traditional two-piece type ball valve is damaged, detachable maintaining is more difficult.
