In view of this, the present invention provides a kind of pivotal support plate of forging ball valve and its forging ball valves, from multiple angles
Solves the problems, such as poor sealing between pivotal support plate and valve body.
To achieve the goals above, the present invention adopts the following technical scheme that：
A kind of pivotal support plate of forging ball valve, including：Supporting plate, the Supporting plate center offer centre bore；
The central hole of the Supporting plate side is connected with seal boss, and the two of the end face of the Supporting plate other side
End and the central hole open up fluted.
Preferably, including：The Supporting plate both sides are provided with guide groove.
Preferably, the groove is inner small and outside big.
Preferably, the elastic component with the groove match is equipped in the groove.
Preferably, the elastic component is made of polytetrafluoroethylene (PTFE), synthetic rubber or polyethylene.
Preferably, the Supporting plate both ends offer multiple location holes.
Preferably, the Supporting plate is connect by location hole and positioning pin with the valve body of the forging ball valve.
Preferably, inclined-plane is provided on the Supporting plate, and the inclined-plane is located at the end face of the seal boss side
Edge.
A kind of forging ball valve, including：The pivotal support plate of above-mentioned forging ball valve.
It can be seen via above technical scheme that compared with prior art, the present disclosure provides a kind of forging ball valves
Pivotal support plate is connected with seal boss in support plate central hole, when using the pivotal support plate, Ke Yitong
It crosses and is arranged the mode of exterior seal ring on seal boss to prevent dust from entering valve core inside；At the both ends and center of Supporting plate
Hole nearby all opens up fluted, when using the pivotal support plate, sealing element is equipped in groove, so that using the pivot
When support plate, significantly more efficient sealing can be realized by the effect of double seal, improve sealing performance.I.e. the present invention from
Multiple angles solve the problems, such as poor sealing between pivotal support plate and valve body.
