Abstract
The coke oven door is provided with a sealing diaphragm which has a sealing strip which comes to engagement with the frame which defines the chamber of the coke oven when the door closes, a plurality of pressure elements each including a housing and an adjustable spring to apply a force to the sealing strip to tightly seal the door in the closed position. The door has a number of radial projections that have cast bores, receiving threaded bolts extending through a common cross-piece to which the housing of the pressure elements are also secured. Counter nuts are mounted on the threaded bolts to adjustably secure the position of the cross-piece and thus the housings of the pressure elements secured thereto, and thereby adjust the force applied by the spring to the sealing strip.
