Automatic adjusting overpressure exhaust valve for airtight tent

The invention provides an automatic overpressure adjusting exhaust valve for an airtight tent, which comprises an exhaust valve front shell, a communication interface, a power supply interface, a circuit mainboard, a driving motor, a valve plate, an exhaust valve back shell, an airtight rubber mat and a clamping plate, and is mainly used for releasing pressure of the airtight tent in an inflation state, so that stable overpressure in the airtight tent can be maintained; the overpressure value in the airtight tent is prevented from being too high or too low; or under the external nuclear biochemical pollution environment, the airtight tent is ventilated, and the pollutant concentration in the airtight tent is reduced; the exhaust valve is provided with a communication interface, the opening degree of the valve plate is automatically adjusted after a control instruction is received according to the internal overpressure value information feedback of the airtight tent, the internal overpressure and leakage amoun
