Disassembly-free density relay verification valve seat structure

The invention relates to the technical field of electric power, in particular to a disassembly-free density relay verification valve seat structure, which comprises a valve seat shell, a separator, a density relay and a calibrator, and is characterized in that the separator is inserted in the valve seat shell, can slide along the length direction of the valve seat shell and divides the valve seat shell into a cavity I and a cavity II; the separator is provided with an air guide hole; when the separator moves in the forward direction, the cavity II is disconnected from the air chamber of the electrical equipment firstly, and the volume of the cavity II is continuously reduced, so that the density relay is calibrated through the calibrator, and then the cavity II is communicated with the air chamber of the electrical equipment again through the air guide hole; and when the separator moves reversely, the cavity II is disconnected from the air chamber of the electrical equipment at first, and the volume of the ca
