Abstract
An automatic pressure control apparatus for an end-face seal plate in a seal mechanism of a high pressure steamer for wet-heat treatment of a textile product comprising; a seal mechanism having a pair of seal rubber rolls located above a hole in the high pressure steamer body, through which the cloth is passed for the purpose of sealing said hole, a seal block for supporting the seal rubber rolls which are freely rotatable, an end-face seal plate supported by the seal block, in pressure contact with the seal rubber rolls and the end face of the seal block so as to be freely slidable in the axial direction of the seal rubber rolls, an end-face seal plate support fitting for support of the end-face seal plate, a pressure control screw supported by means of a support fitting fixed to the seal block so as to be freely slidable in the axial direction of the seal rubber rolls, and a press-down plate movable in the axial direction of the seal rubber rolls by means of the pressure control screw, a pressure detector provided between the press-down plate and the end face of the seal rubber rolls for detecting the contact pressure between the end faces of the seal rubber rolls and the end-face seal plate, and an operation mechanism driven by means of a pressurized fluid to move said pressure control screw back and forth, thus allowing the end faces of the seal rubber rolls to make contact with the end-face seal plate under an appropriate amount of pressure, and a modification thereof.
