8 results about "Boiler explosion" patented technology

A boiler explosion is a catastrophic failure of a boiler. As seen today, boiler explosions are of two kinds. One kind is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level. Corrosion along the edges of lap joints was a common cause of early boiler explosions.

Double-adjustment magnetic pre-tightening explosion door device

The invention discloses a double-adjustment magnetic pre-tightening anti-explosion door device, and relates to the technical field of boiler anti-explosion doors, the double-adjustment magnetic pre-tightening anti-explosion door device comprises a boiler pipeline and a mounting bent seat welded on the boiler pipeline, the mounting bent seat is connected with a mounting seat, and the mounting seat is connected with a connecting cover; the device further comprises a first gland and a second gland. The first gland abuts against the opening edge of the mounting base, and a spring is arranged between the first gland and the top wall of the connecting cover. The second gland is arranged on the outer top wall of the connecting cover and connected with a magnet fixed to the outer top wall of the connecting cover in a magnetic attraction mode. The second gland is in threaded connection with a bolt, and the bolt penetrates through the top wall of the connecting cover to abut against the vertical rod on the top face of the first gland. The magnetic attraction force of the second gland and the magnet acts on the first gland through the bolt and the vertical rod, and then it is guaranteed that the first gland is stably sealed before the pressure of the pressure relief channel reaches the detonation threshold value. According to the anti-explosion door, the elastic force of the spring and the pre-tightening force of the magnet bolt are combined, so that the pressure relief channel can keep stable sealing when the detonation threshold value is not reached, leakage is effectively prevented, and the reliability of the anti-explosion door is improved.
