A boiler evaporator tube leak detection device

Abstract

The utility model belongs to evaporator pipe leakage detection technical field discloses a kind of leakage detection devices of boiler evaporator pipe, including evaporator pipe, still include: fixed base, fixed base is sleeved on the outside of evaporator pipe;Elastic diaphragm, elastic diaphragm is annular, and the inner edge of elastic diaphragm is installed on fixed base, and the outer surface of elastic diaphragm extends to evaporator pipe wall direction;Alarm mechanism, alarm mechanism includes bearing box, and microswitch, signal transmitter and power module are installed in bearing box, and there is trigger lever between microswitch and elastic diaphragm, and one end of trigger lever is connected with the outer edge of elastic diaphragm, and other end is connected with microswitch;Heat insulating layer, heat insulating layer is located between evaporator pipe and elastic diaphragm.The utility model directly senses leakage fluid by elastic diaphragm mechanical deformation, then combines L-shaped trigger lever linkage microswitch, solves the hysteresis problem of traditional pressure / temperature monitoring, and realizes the rapid positioning of leakage point.
