Problems solved by technology
[0002] In the prior art, the sealing ring of the central device of the vulcanizer is placed in the gland of the central device with a tetrafluoro pad to prevent steam leakage. The tetrafluoro pad has poor high temperature resistance and is easy to age. It usually takes 2 to 3 months Replace the PTFE pad once; since the vulcanizer needs to be warmed up for a long time, it is the most taboo for the manufacturer to stop the vulcanizer. This frequent shutdown and replacement seriously delays production

The invention discloses a sealing mechanism for a center device of a vulcanizing machine. The sealing mechanism comprises the center device arranged on a vulcanizing machine body. The upper portion of the center device is provided with a gland in an inverted T shape and provided with a concave hole of which the shape corresponds to the shape of the gland. A circle of abutting ring is further arranged on the lower portion of the concave hole. The bottom end of an inserting part is provided with a circle of groove. A sealing ring is a graphite sealing ring. The gland is inserted and fixed into the concave hole and enables the sealing ring to be clamped between the groove and the abutting ring. A circle of pure copper seal is further arranged at the joint of the center device and a lower annular cylinder head. The sealing device mechanism for the center device of the vulcanizing machine is durable and long lasting; compared with traditional sealing modes, the operating life can be prolonged by 2-3 times, and the operating life of the sealing mechanism can further be prolonged by adjusting bolts of the gland.
Description
technical field [0001] The invention relates to a sealing mechanism of a central device of a vulcanizing machine. Background technique [0002] In the prior art, the sealing ring of the central device of the vulcanizer is placed in the gland of the central device with a tetrafluoro pad to prevent steam leakage. The tetrafluoro pad has poor high temperature resistance and is easy to age. It usually takes 2 to 3 months Replace the PTFE pad once; since the vulcanizer needs to be warmed up for a long time, it is the most taboo for the manufacturer to stop the vulcanizer. This frequent shutdown and replacement seriously delays production. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a more durable sealing mechanism for the central device of the vulcanizer. [0004] The technical solution of the present invention is: a sealing mechanism for the central device of a vulcanizing...
