Abstract

The invention belongs to the field of vacuum metallurgical equipment, and in particular relates to an oil cylinder lifting type isolating valve special for a vacuum induction furnace, which is applied between a main chamber and a feeding cabin or temperature measurement cabin of the vacuum induction furnace for isolating or communicating two chamber parts. The isolating valve comprises a valve body (1), wherein a track (3), a valve plate (2), a lifting mechanism (4) and a push and pull mechanism (5) are arranged in the valve body (1); the valve plate (2) is slidably connected with the track (3); one end of the lifting mechanism (4) is fixedly connected with the valve body (1), while the other end is connected with one end of the track (3) through a shaft; the other end of the track (3) is connected with the valve body (1) through the shaft; and one end of the push and pull mechanism (5) is fixedly connected with the valve plate (2), while the other end is connected with the valve body (1) through a shaft. The isolating valve has the characteristics of high sealing property, heat insulation, long service life and the like.

Description

technical field [0001] The invention belongs to the field of vacuum metallurgical equipment, and in particular relates to a special oil cylinder lifting isolation valve for a vacuum induction furnace that is applied between a main chamber of a vacuum induction furnace and a feeding bin or a temperature measuring bin to isolate or connect the two chambers. Background technique [0002] Large-scale vacuum induction furnaces are currently the smelting equipment for smelting high alloys, and the development of the material industry requires the purity of the smelted alloys to be higher and higher. In addition to requiring low impurity content, it also requires less gas content. [0003] The structure type of the isolation valve currently used in China between the main chamber of the vacuum induction furnace and the feeding bin or the temperature measuring bin is mainly that the cylinder rod of the cylinder outside the valve body passes through the valve plate which is pushed and ...
