Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in figure 1, the chimney inner cylinder connecting structure capable of preventing water leakage and air leakage comprises an upper cylinder body 4 and a lower cylinder body 5, wherein the lower cylinder body 5 is connected with lower flanges 1-5 in a welded mode, the upper cylinder body 4 is connected with upper flanges 1-2 in a welded mode, the upper cylinder body 4 is further provided with upper movable flanges 1-1, the upper movable flanges 1-1 are fixedly connected with the lower flanges 1-5 through connecting bolts 1-6, a sealing structure is arranged between the upper flanges 1-2 and the lower flanges 1-5 and comprises inner positioning ring plates 1-3, outer positioning ring plates 1-7 and sealing strips 1-4 arranged between the inner positioning ring plates 1-3 and the outer positioning ring plates 1-7, the bottom of the upper cylinder body 4 is connected with an inserting ring 2 extending into the lower cylinder body 5 in a welded mode, and a smoke isolating check ring 3 is arranged at the top of the lower cylinder body 5.

Furthermore, the inner positioning ring plate 1-3 and the outer positioning ring plate 1-7 are both connected with the lower flange 1-5 in a welding mode or one of the positioning ring plates is connected with the lower flange 1-5 in a welding mode, and the other positioning ring plate is connected with the upper flange 1-2 in a welding mode.

Furthermore, the thickness of the sealing strips 1-4 is larger than that of the inner positioning ring plate 1-3 and the outer positioning ring plate 1-7, and the sealing strips are coated with adhesive layers.

Further, the shape of the sinking and inserting ring 2 is a conical ring shape with the caliber gradually decreasing from top to bottom.
