[0053] By setting the sealing ring 19, gas leakage through the connecting hole 601 is avoided.

[0054] The working principle of the safety pressure relief device for the chemical reaction kettle is as follows:

[0055] When the pressure inside the reaction kettle is too large during use, the gas passes through the inside of the valve body 1 and pushes the sealing plate 4, so that the first spring 503 is compressed, the gas is discharged from the valve body 1 through the through slot 3, and the pressure relief effect is achieved, the worker controls the connecting rod 602 to move along the connecting hole 601, so that the compression ring 603 moves along the direction of the connecting hole 601, so that the compression ring 603 can press and combine the first spring 503, and the lifting of the compression ring 603 facilitates the worker to adjust the elastic force of the first spring 503, so as to cope with the pressure relief work under different processes.
