A rubber ring sealing structure with cooling function

Abstract

The invention belongs to a rubber ring sealing technology, and relates to a rubber ring sealing structure with a cooling function. The rubber ring sealing structure with the cooling function comprisesa to-be-treated pipe material (1), a furnace pipe (2), a sealing rubber ring (3), a sealing flange base (4), connecting bolts (5), an annular blocking piece a (6), a cooling liquid inlet a (7), a cooling liquid outlet b (8), a vacuumizing pipeline (9), an annular blocking piece b (10), a cooling liquid inlet a (11), a cooling liquid outlet b (12) and cooling liquid (13). According to the rubber ring sealing structure with the cooling function, an annular cavity structure is arranged at the position, close to the sealing rubber ring installed on the sealing flange base, of the furnace pipe through welding annular blocking, an annular cavity is filled with the cooling liquid to form a circular cooling system, and then the cooling purpose is achieved; and the temperature around the rubber ring can be effectively lowered in the heat treatment process, therefore, the working performance and the service life of the rubber ring are guaranteed, and the sealing reliability is guaranteed.

Description

technical field [0001] The invention belongs to rubber ring sealing technology and relates to a rubber ring sealing structure with cooling function. Background technique [0002] The technical problem to be solved: Precision pipes need heat treatment during processing. In order to prevent the pipes from being oxidized during heat treatment, the pipes need to be carried out in a closed state with low oxygen content. The specific process of treatment is to put a certain amount of The pipes to be processed are put into the furnace tube. The furnace tube is an open tool with a closed end and a sealed structure at the other end. After the air in the furnace tube is drawn out, the furnace tube with the tubes to be processed is put into the furnace for heat treatment. There is an apron sealing device at the open end of the furnace tube. During the heat treatment process, the heat is transferred to the sealing part through the furnace tube. The apron is deformed after being heated, ...

AI Technical Summary

Problems solved by technology

There is a rubber ring sealing device at the open end of the furnace tube. During the heat treatment process, the heat is transferred to the sealing part through the furnace tube. The rubber ring will be deformed after being heated, which will affect the life of the rubber ring, and will lead to a decrease in the sealing effect, or even a failure of the seal.

[0003] Existing sealing structures such as figure 1 As shown, the axial rubber ring seal structure is used between the two flange faces. During the heat treatment process, the heat will be transferred to the flange sealing part, which will reduce the life of the sealing rubber ring, reduce the sealing effect, and even fail.
