Problems solved by technology

[0003]Currently existing aging test platforms use cylindrical or dumbbell-shaped samples for testing, this method cannot intuitively judge the service life of rubber rings
Moreover, in the existing devices for testing the life of O-ring seals, the contact area between the background gas used for aging and the seal rings is too small, the acceleration efficiency is low, and it is impossible to carry out efficient aging tests on O-ring seals

Abstract

The invention discloses an aging test device and an aging test method for an O-shaped sealing ring. The aging test device for the O-shaped sealing ring comprises an air valve, a barometer, a flange top cover, at least one flange plate and a flange bottom cover, the flange plate and the flange bottom cover are each provided with an O-shaped groove for installing an O-shaped sealing ring, a plurality of through air holes are formed in each O-shaped groove, and the through air holes are used for enabling aged background gas to make full contact with the O-shaped sealing rings; a through hole is formed in the center of the flange top cover, the air valve is installed at the top of the flange top cover through the through hole, a through hole is formed in the side face of the air valve, and the barometer is connected with the air valve through the through hole. The flange top cover, the flange plate and the flange bottom cover are detachably connected in sequence from top to bottom. The aging test device is simple in structure and convenient to operate, the contact area between the O-shaped sealing ring and background gas used for aging can be increased, the O-shaped sealing ring can make full contact with the background gas, and therefore the acceleration efficiency is improved, and an efficient, rapid and accurate aging test is achieved.

Description

technical field [0001] The invention relates to the technical field of aging test for sealing rings, in particular to an aging test device and an aging test method for an O-shaped sealing ring. Background technique [0002] In gas-insulated equipment in power systems, O-shaped rubber seals are often used to improve the airtightness of the equipment. With the restrictions on the use of SF6, more and more new environmentally friendly insulating gases have been proposed, including some corrosive gases. In order to ensure the airtightness of these gases during use, it is necessary to carry out an aging test on the O-shaped rubber sealing ring with these gases as the background gas, and judge the service life of the rubber in the corresponding gas environment by measuring the leakage rate. [0003] At present, the existing aging test platform uses cylindrical or dumbbell-shaped samples for testing, and this method cannot intuitively judge the service life of the rubber ring. Mo...
