| titleOfInvention | A wear-resistant ball valve for polysilicon production that is convenient for silicon powder transportation |
| abstract | The invention discloses a wear-resistant ball valve for polysilicon production which is convenient for conveying silicon powder, comprising a valve seat, a valve core and a valve stem. A ring groove and a groove are symmetrically opened on the inner side of the ring groove. The ring groove and the groove communicate with each other. The inner wall of the ring groove is slidably connected with a sealing ring A and a sealing ring B. The outer part of the groove is provided with a linkage mechanism, and the interior of the groove is provided with a lubricating mechanism. In the present invention, by simultaneously rotating the control knob on the same side, the reel winds the connecting rope, so that the sealing ring A is completely separated from the outer side of the valve core, and the sealing ring B is tightly abutted on the outer side of the valve core, which can be achieved. Switching from sealing ring A to sealing ring B prolongs the service life of the wear-resistant ball valve; and in the process of winding the connecting rope on the reel, it can prevent the valve stem from rusting and jamming, causing the wear-resistant ball valve to malfunction. use. |
