| description | The utility model discloses a cast steel ball valve with a protective structure, which comprises a valve body, the top of the valve body is provided with a rotating handle, the right side of the rotating handle is provided with a wooden handle, and the right side of the rotating handle and the left side of the wooden handle are respectively and fixedly connected with a first disc and a second disc. The wood handle is adopted, the characteristic that the heat conductivity coefficient of the wood handle is low is utilized, so that hands of an operator are protected from being scalded, the rubber sleeve is arranged, secondary protection is achieved, when the operator needs to replace the wood handle, the operator pulls the guide rod towards the back face, the guide rod is separated from the gear, locking of the gear is relieved, and the operator can replace the wood handle. Then an operator rotates a handle to drive a gear to rotate, a circular ring is driven to rotate through teeth, then a connecting rod is dri |
