Detailed Description

Example (b): as shown in fig. 1 to 2, the steam exhaust silencer of the utility boiler comprises an outer cylinder 10 and an inner cylinder 20, wherein the inner cylinder 20 is arranged in the outer cylinder 10, the lower part of the inner cylinder 20 extends out of a middle through hole 11 of a bottom plate of the outer cylinder 10, an annular connecting plate 21 is fixed on the outer side wall of the lower part of the inner cylinder 20, and the annular connecting plate 21 is fixedly connected to the bottom surface of the bottom plate of the outer cylinder 10 through bolts; a sealing gasket is clamped between the annular connecting plate 21 and the bottom plate of the outer cylinder 10;

an upper central through hole 12 is formed in the middle of the top plate of the outer cylinder 10, a screw part of the upper fixing bolt 1 is inserted into the upper central through hole 12, a connecting block 22 is fixedly welded in the middle of the top surface of the inner cylinder 20, and the bottom end of the screw part of the upper fixing bolt 1 extends out of the bottom surface of the upper central through hole 12 and is in threaded connection with a middle threaded hole of the connecting block 22;

the rotating portion of the upper fixing bolt 1 is pressed against the top surface of the top plate of the outer cylinder 10.

Further, a seal ring 2 is clamped between the rotating part of the upper fixing bolt 1 and the top surface of the top plate of the outer cylinder 10.

Further, the sound absorbing layer 3 is fixed on the bottom surface of the top plate of the outer cylinder 10 and the inner side wall of the outer cylinder 10.
