摘要：In a stationary gas jumper arrangement (6) for a coke oven with adjacent coke oven chambers (2, 2',...), each of which has a gas opening (5, 5',...), the gas jumper arrangement (6) covers gas openings (5, 5') of two neighbouring coke oven chambers (2, 2') in each ca with one cover chambers (7, 7') and the two cover chambers (7, 7') are connected line-wi by a jumper pipe (9), and covers (8, 8') covering the gas openings (5, 5') during charging of a coke oven chamber (2, 2') can be moved within the cover chambers (7, 7') by means of an actuation device (12) from an open position into a clod position and t into rotary motion. …To ensure tightness of the gas openings (5, 5') with the covers (8, 8') put in place even in the event of major pressure fluctuations and to allow inertisation of the gas jumper arrangement (6), both the covers (8, 8') and the rim of each gas opening (5, 5') each have a aling surface (24, 24', 25, 25') of the type of a valve at, which aling surfaces fit one another and are presd against one another in the clod position of the cover (8, 8'), and a gas line (10) feeding an inert gas such as nitrogen leads into the gas jumper arrangement (6) and the latter is subjected, with the
covers (8, 8') clod, to an inert gas pressure which is above the pressure within the coke oven chambers. ……
