Further, the hand wheel assembly include hand wheel and drive assembly, drive assembly include the transmission casing and locate intermeshing's in the transmission casing worm wheel and worm, turbine axle center department be connected with the right-hand member of dwang, the worm upper end be connected with the hand wheel through the action bars. Because the transmission ratio of worm gear is lower, and then carry out fine adjustment degree of opening and shutting, the adaptability is high.
Furthermore, the right end of the rotating rod is connected with the turbine through a flat key.
Furthermore, the dwang right-hand member evenly seted up a plurality of location jack along the circumferencial direction, the locating pin is installed to the upper wall of transmission casing, the locating pin on the cover be equipped with reset spring, the afterbody butt of locating pin in adjusting nut's lower extreme, adjusting nut cover locate the lower extreme of action bars, the lower extreme of action bars be equipped with adjusting nut matched with external screw thread. Through locating pin and adjusting nut, can make the fixed axis of rotation of locating pin, be located a specific water level, avoid influencing the water yield size of regulation under the water conservancy is strikeed.
Furthermore, the hand wheel is in a quincuncial shape.
Furthermore, the rotating rod is sleeved with a rotating shaft sealing ring.
Furthermore, a sealing sleeve is arranged at the joint of the outer shell and the transmission shell.
Compared with the prior art, the utility model has the advantages of:
the utility model discloses a set up in the hand wheel assembly of square ball valve one side, avoid adjusting the operation in the space that the pipeline was located, provide bigger operating space margin, more be favorable to the flow size of meticulous regulation square ball valve.
