Sealing device in a high pressure steamer

摘要

A sealing device in a high pressure steamer which includes a pressure reducing chamber disposed between a cloth material inlet port of a drum body of the steamer and rubber seal rolls. The sealing device further includes a high pressure air supply pipe connected to the pressure reducing chamber; heat resistant seal rolls disposed beneath the pressure reducing chamber at a cloth passing port provided in the pressure reducing chamber on the side of the drum body of the steamer, the heat resistant seal rolls being provided for the purpose of making the pressure reducing chamber into a high pressure air chamber preventing the steam inside the steamer drum body from coming into the chamber; and a water reservoir which is formed with the frame thereof disposed close to each of the rubber seal rolls to cover about 1/4 of the circumference of the rubber seal roll. The surfaces of the rubber seal rolls are constantly washed clean by the water contained in the water reservoir and by other cleaning means.
