The application discloses a kind of boiler heating surface wall temperature detection device and detection method, including fixed component, including boiler, heating surface, support, thermocouple, cladding metal, data transmission piece, display piece and teletransmission piece, the heating surface is located in the boiler, the support is set to the side of the boiler.This application has beneficial effects: by setting fixed component for temperature monitoring to heating surface, by setting clamping assembly for thermocouple is clamped, and a force to heating surface is applied to thermocouple, so that thermocouple does not occur contact bad phenomenon, solve the thermocouple and the poor contact of boiler heating surface, lead to the temperature data obtained is low, so that worker cannot adjust the temperature of boiler in time, prone to boiler explosion and other safety accidents.

This utility model discloses a boiler explosion-proof safety valve device, including a valve body, an adjusting screw, an adjusting spring, a guide sleeve, a diaphragm, and a valve stem pressure plate. An air pump is fixedly connected to one side of the valve body, and a nitrogen inlet pipe is fixedly connected to one end of the air pump. A support column is fixedly connected to one side of the valve body, one of which is hollow. A guide ring is fixedly connected to the support column, and a connecting pipe is fixedly connected to one side of the upper end of the guide ring. The upper end of the connecting pipe is fixedly connected to the output end of the air pump. A support ring is fixedly connected inside the connecting pipe, and support rods are fixedly connected to the four sides of the bottom end of the support ring. A movable plate is sleeved on the support rod. This utility model forms a check valve structure by setting an air pump, a nitrogen inlet pipe, a connecting pipe, a support ring, support rods, a movable plate, a limit ring, and an air inlet hole on the upper side of the valve body diaphragm. This allows the air pump to intake air into the guide ring and the valve body, thereby forming a damping structure on the upper side of the diaphragm, reducing vibration and impact at the valve core and valve seat, and improving the valve life.

The utility model discloses a kind of double-adjusting magnetic pre-tightening explosion door devices, it is related to the technical field of boiler explosion door, including boiler pipeline and the mounting bend seat welded on boiler pipeline, mounting bend seat is connected with mounting seat, and mounting seat is connected with connecting cover;Still including gland one and gland two;Gland one is abutted with the opening edge of mounting seat, and spring is equipped between gland one and the top wall of connecting cover;Gland two is located in the outer top wall of connecting cover, and magnet magnetically attracted connection with the outer top wall of connecting cover fixed on;Gland two is screw-threaded with bolt, and bolt is through the top wall of connecting cover and the vertical rod of the top surface of gland one abutted;The magnetic attraction of gland two and magnet is acted on gland one by bolt and vertical rod, and then guarantee the stable sealing of gland one before the pressure of pressure relief passage reaches detonation threshold value.The utility model combines the elastic force of spring and the pre-tightening force of magnet bolt, so that pressure relief passage can maintain stable sealing when not reaching detonation threshold value, improve the reliability of explosion door.
