After the replacement is completed, the upper cover is put back in place, the cylinder extends, driving one end of the connecting rod to rise and the other end to descend, and the pressing block is driven close to the upper cover, exerting downward pressure on the upper cover, pressing and fixing the upper cover, and completing the repair and replacement. Compared with the currently available technology, the internal components of the boiler will be damaged by high-temperature corrosion during use, and the boiler components are usually installed and fixed by welding, so that when the internal components of the boiler are repaired or replaced, the outer layer of the boiler needs to be removed as a whole, which makes the boiler maintenance time-consuming and labor-intensive, greatly increases the maintenance cost, and is inconvenient for the maintenance of the boiler. The heating boiler which maintains a constant temperature can repair and replace the interior without removing the outer layer of the boiler, which saves time and labor, reduces the maintenance cost, and is convenient for the maintenance of the boiler.
