Edge.
A kind of forging ball valve, comprising: the pivotal support plate of above-mentioned forging ball valve.
It can be seen via above technical scheme that compared with prior art, the utility model, which discloses, provides a kind of forging ball
The pivotal support plate of valve is connected with seal boss in support plate central hole, can when using the pivotal support plate
Prevent dust from entering valve core inside in a manner of by being arranged exterior seal ring on seal boss；Supporting plate both ends and
Centre bore nearby all opens up fluted, and when using the pivotal support plate, sealing element is equipped in groove, so that using should
When pivotal support plate, significantly more efficient sealing can be realized by the effect of double seal, improve sealing performance.That is this reality
Solve the problems, such as that leakproofness is poor between pivotal support plate and valve body from multiple angles with novel.
