Abstract

The invention provides a sealing screw assembly and a connecting screw thereof. The sealing screw assembly comprises the connecting screw, the connecting screw comprises a screw head and a threaded connecting section, and the screw head is in a step shape comprising a large-diameter section and a small-diameter section. The small-diameter section is located between the large-diameter section and the threaded connecting section, and a sealing ring is mounted on the small-diameter section. According to the sealing screw assembly, through the sealing ring on the small-diameter section of the screw head, the airtightness ata connecting screw hole can be ensured when the large-diameter section of the screw head and a connecting face plate are pressed, fastened connection is achieved, and the sealing performance of the connecting position is ensured.

Description

technical field [0001] The invention relates to a connecting element, in particular to a sealing screw assembly and its connecting screw. Background technique [0002] At present, more and more high-voltage electrical equipment filled with insulating gas are used in the power grid. During the assembly process of these high-voltage electrical equipment, electrical components need to be fixed in the gas box. Like this, the fastening screw that is used for fixing these electrical equipment not only needs to have higher pressure-bearing capacity, also needs to have airtight performance, to ensure that the gas in the box will not leak from the screw connection position, but most of the existing screws only It plays the role of fixed connection and does not have high air tightness. Contents of the invention [0003] The purpose of the present invention is to provide a sealing screw assembly capable of ensuring airtightness, and at the same time, the present invention also provi...
