The invention discloses a self-pressure-relief compressed air storage device for a flame photometer. The device comprises an air pressure tank body, a self-pressure-relief threaded hole is formed in the bottom of the air pressure tank body, locking end covers, self-locking expansion sleeves, air inlet and outlet threaded straight flow guide columns, compressed air particle filters and filter limiting rings which are distributed from outside to inside are symmetrically arranged at two ends of the air pressure tank body, the self-locking expansion sleeves are sleeved with air inlet pipes, the self-locking internal threads are arranged on the inner walls of the self-locking expansion sleeves, an open cavity is formed in one side of each air inlet and outlet threaded straight flow guide column, an external threaded hole is formed in the other side of each air inlet and outlet threaded straight flow guide column, the periphery of each external threaded hole is provided with a first external thread, the compressed air particle filters and the filter limiting rings are arranged in the open cavities, and the self-locking expansion sleeves are arranged on the air inlet pipes in a sleeving mode through the self-locking internal threads. The self-pressure-relief compressed air storage device for the flame photometer can store compressed air, is suitable for any external compressed air inlet mode, and overcomes the defect that external air cannot be used in the past.
Description
technical field [0001] The invention relates to the technical field of flame photometers, in particular to a self-relieving compressed air storage device for flame photometers. Background technique [0002] The flame photometer uses the flame as the excitation light source to excite the atoms of the measured elements, and uses a photoelectric detection system to measure the characteristic radiation intensity emitted by the excited elements. The Sherwood Model 410 is a single-channel, cryogenic flame photometer for the measurement of Na, K and Ca elements in samples. The device has a safety device that automatically shuts off the gas line when the flame is not lit or the flame goes out during the measurement. There is also an air pressure valve, if the air pressure value is lower than a certain standard, the flame will not be ignited or the flame will be extinguished. The pressure of the air source is 1kg / cm 2 (14psig), and keep it clean and dry, with a flow rate of 6 lite...
