As can be seen from the above, when P/(π r) 2 )<k (x 1+ x 2), the first baffle plate of the first pressure monitoring mechanism moves to one end far away from the elastic mechanism under the action of the elastic force of the elastic mechanism; when P/(π r) 2 )>k (x 1+ x 2), the second baffle of the second pressure monitoring mechanism moves to the end close to the elastic mechanism.
In addition, when a movable plate of the pressure regulating mechanism is in a balanced state, the two sides of the movable plate are stressed in a balanced manner, the tension value of the second spring is equal to the pressure inside the tank body, when the pressure regulating mechanism is used for automatically relieving pressure, when a set pressure value of the tank body is reached, gas in the tank flows out from the gas outlet to cause pressure to the movable plate, the stop block slides upwards in the groove, the stop block is staggered with the gas outlet hole, automatic pressure relief is realized, when the pressure value in the tank body reaches a set value, the second spring drives the movable plate and the stop block to automatically reset, and the stop block and the gas outlet are sealed and shielded. When the pressure regulating mechanism regulates pressure, if the chemical reaction needs higher pressure, the rotating handle is screwed clockwise, the screw rod moves downwards to compress the second spring, the tension value of the second spring to the moving plate in a balanced state is increased, and the set pressure value born in the tank body is increased.
