Natural gas alarm pretreatment system for refractory brick production

The utility model belongs to the field of refractory brick production, and particularly relates to a refractory brick production natural gas alarm pretreatment system which comprises a taper pipe, a natural gas conveying pipeline and a mounting plate, a butt joint shell is fixedly connected to the natural gas conveying pipeline, a pressure relief opening is fixedly connected to the butt joint shell, and an automatic pressure relief mechanism is arranged in the pressure relief opening. A mounting mechanism is arranged between the pressure relief opening and the mounting plate, a gas detector is arranged on the mounting plate, and a detection sensing probe and an alarm are arranged on the gas detector. The butt joint shell is arranged on the natural gas conveying pipeline, the pressure relief opening is formed in the butt joint shell, and the automatic pressure relief mechanism is arranged in the pressure relief opening, so that when the air pressure in the natural gas conveying pipeline rises, the plug is jack
