The utility model discloses a theory of operation:

when the gas-liquid in the reaction kettle reacts, the hand valve needs to be opened, the gas pressure rises during the reaction, when the pressure in the reaction kettle is higher than a normal value, the high-pressure gas in the reaction kettle enters the vent pipe, part of the high-pressure gas enters the actuating mechanism from the pressure taking port through the vent pipe, the pneumatic pressure of the gas is larger than the pulling force of the spring at the moment, the high-pressure gas pushes the pull rod downwards to push the upper valve core and the lower valve core downwards, the pneumatic pressure valve is opened, the helium gas is filled into the exhaust pipe through the gas inlet pipe, other high-pressure gas flows upwards to flush the safety valve and continuously rises into the exhaust pipe, because the vent pipe is arranged below the control valve, the helium gas is firstly filled into the exhaust pipe to dilute the high-pressure gas which enters the exhaust pipe later, so that the formed mixed gas is in the explosion limit range and has no explosiveness, and finally the mixed gas, when the pressure in the reaction kettle is recovered to a normal value, the pneumatic pressure of the gas in the reaction kettle is smaller than the tension of the spring, the spring is tensioned, and the pneumatic electromagnetic valve is closed, so that the whole process of emptying and pressure relief is completed, and the use safety of the reaction kettle is ensured.

The utility model has the advantages that: the utility model has high safety performance and high pressure relief speed, when the pressure in the reaction kettle is higher than a normal value, the high-pressure gas enters the actuating mechanism and pushes the pull rod, so that the pneumatic pressure valve is opened, helium gas is filled into the exhaust pipe through the air inlet pipe, and the gas discharged into the exhaust pipe in the reaction kettle is protected by inert gas, so that the discharged gas is prevented from being exploded, the safety of emptying the reaction kettle is ensured, the pressure relief is carried out on the reaction kettle, and the normal work of the reaction kettle is ensured; the utility model discloses a gas in the reation kettle carries out opening and close of pneumatic pressure valve, need not artifical or control mechanism and controls, and simple structure practicality is strong, and low in production cost is honest and clean.
