| titleOfInvention | Pressure ring oil cylinder piston |
| abstract | The utility model relates to the field of electric furnace and particularly relates to a pressure ring oil cylinder piston applied to a holder of an iron alloy electric furnace. The pressure ring oil cylinder piston at least comprises a rear sealing end cover located at the rear end of an oil cylinder and a piston body in the oil cylinder. The pressure ring oil cylinder piston is characterized in that the piston body in the oil cylinder is composed of a piston rear section and a piston front section, and a large insulation mica mat is fixed at the contact position of the piston front section and the piston rear section. The pressure ring oil cylinder piston enables the piston body to be divided into a front section and a rear section to be manufactured, mica insulation is added between the front section and the rear section, and the piston body butts against the working end of a copper content element and is thoroughly separated from the sealing end of the oil cylinder. The pressure ring oil cylinder piston can be operated normally even if electric connection is generated at the top end of the piston, cannot cause a spark phenomenon between the inner wall of the oil cylinder and the outer surface of the piston, and achieves insulation protection functions. |
