Abstract

The invention discloses a sealing ring, a split sealing structure and a processing technology for the sealing ring, which include a ring-shaped sealing ring body, the sealing ring body is broken in the radial direction to form two semicircular sealing parts, and the sealing parts are passed through each other. The mating fracture surface seals the connection. The present invention adopts the principle of partial heating and thermal expansion and contraction to form two semicircular seals on the sealing ring body, and a fracture surface that cooperates with each other is formed between the seals, and a complete seal can be formed through the cooperation of the two fracture surfaces. Compared with the traditional sealing method, each plane changes the flow direction and flow velocity once, which greatly increases the number of changes in the liquid flow direction, thereby greatly improving the sealing effect. Due to the use of local heating to form sections, compared with many As far as the processing of a mating surface is concerned, high-precision processing equipment is not required, and the processing time is greatly shortened, thereby greatly reducing production costs.

Description

technical field [0001] The invention relates to the field of mechanical seals, in particular to a seal ring, a split seal structure and a processing technique for the seal ring. Background technique [0002] Mechanical seal refers to a device that prevents fluid leakage by at least one pair of end faces perpendicular to the axis of rotation, under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism, and the cooperation of the auxiliary seal to keep fit and slide relative to each other. . The elastic loading mechanism and the auxiliary seal are mechanical seals of metal bellows, which we call metal bellows seals. In light-duty seals, rubber bellows are also used as auxiliary seals. Rubber bellows have limited elasticity, and generally need to be supplemented by springs to meet the loading elasticity. "Mechanical seal" is usually referred to simply as "mechanical seal". [0003] The mechanical seal is one of the most frequent...
