In this technical scheme, considering that the bridge pipe 200 in the existing coking plant is mostly in a socket structure, the upper socket joint 110 and the lower socket joint 150 are respectively arranged at the top end and the bottom end of the outer cylinder 120 and are used for connecting with the bridge pipe and the gas collecting pipe, so that the maintenance-free rotary curved surface pressure monotone valve for the coking chamber of the coke oven is applicable to most coke ovens with the same structure, and has stronger universality. The dimensions of the upper socket joint 110 and the lower socket joint 150 can be adjusted according to the adapted bridge pipe and gas collecting pipe, without adjusting the main structure of the monotone valve 100, such as the outer cylinder 120, the inner cylinder 130 and the valve cover 140, so that the main structure of the monotone valve 100 has a wider application range. When the bridge pipe 200 needs to be replaced, the detachable connection between the outer cylinder 120 and the upper socket joint 110 can be released, so that the main structure of the monotone valve 100 is prevented from being damaged when the bridge pipe is replaced; preferably, the upper socket joint 110 and the lower socket joint 150 are detachably coupled to the outer tub 120 by bolts, respectively. When in use, raw gas enters the inner cylinder 130 through the bridge pipe 200 and the upper socket joint 110 through the carbonization chamber, and then the flow area of the raw gas is regulated by regulating the staggered area of the bottom ends of the valve cover 140 and the inner cylinder 130, so as to realize the regulation of the flow pressure of the raw gas; and then into the header through the lower socket 150.

In another embodiment, the bottom end of the upper socket joint 110 is detachably connected with the top end of the outer cylinder 120, and an upper through hole 112 is formed in the middle of the upper socket joint, so as to conduct raw gas; the top end of the upper socket joint 110 is provided with an annular sinking groove 111.
