Intrinsic safety type flowmeter with flame-proof structure convenient to replace

The utility model discloses an intrinsic safety type flowmeter with a conveniently replaceable explosion-proof structure, which relates to the technical field of flowmeters and comprises a main meter and a pressure relief mechanism, a detachable mounting mechanism is arranged on the inner side of the middle of the upper portion of the main meter, and the pressure relief mechanism for pressure relief and explosion prevention is arranged on the lower portion of one side of the main meter. Compared with an existing device, the intrinsic safety type flowmeter with the explosion-proof structure convenient to replace has the advantages that through the reset spring and the plugging head, the intrinsic safety type flowmeter can be downwards punched and opened when the pressure in the main body meter is too large, so that a circulating medium in the main body meter can be discharged through the circulating opening and the connecting pipe, the overpressure in the main body meter can be reduced, and the safety of the m
