AI Technical Summary
Technical Problem
In existing shaft construction, the sealing performance between the sealing cover and the shaft is not good, which easily leads to air leakage, affecting construction quality and safety.
Method used
The system employs a combination structure of annular sealing gasket and annular pressure plate. The annular sealing gasket is placed between the shaft and the sealing cover, and is made to fit tightly against the inner wall of the shaft and the outer side of the sealing cover through the annular pressure chamber and air pressure, thereby enhancing the sealing effect.
Benefits of technology
It significantly improves sealing performance, reduces air leakage, ensures a dry working environment inside the airtight chamber, and improves construction quality and safety.

Abstract
The application discloses a sealing structure between a shaft and a sealing cover, and relates to the technical field of shaft construction. The sealing structure between the shaft and the sealing cover comprises an annular sealing pad, which is arranged between the shaft and the sealing cover and is tightly attached to the inner wall of the shaft and the outer side surface of the sealing cover respectively; the top of the annular sealing pad is provided with an annular pressing plate in contact with the annular sealing pad, the annular pressing plate is connected with the sealing cover, the bottom of the annular sealing pad is provided with an annular pressure cavity, and the annular pressure cavity has a structure that the upper end is closed and the lower end is open. According to the application, the annular pressure cavity is arranged at the bottom of the annular sealing pad, the gas in the air-tight cabin enters the annular pressure cavity and generates extrusion force on the two side walls of the annular pressure cavity, the two sides of the annular sealing pad are more tightly attached to the inner wall of the shaft and the outer side surface of the sealing cover, and the sealing effect is further enhanced. Therefore, the sealing structure disclosed by the application significantly improves the sealing performance and is not prone to the gas leakage phenomenon.
