Inflatable safety valves work by allowing air or gas to enter and inflate the device, while preventing it from escaping once the desired pressure is reached. These valves typically consist of a one-way mechanism that opens to allow inflation and then closes to seal the device. This helps to maintain the desired pressure and prevent over-inflation, ensuring the safety and functionality of the inflatable device. When the pressure inside the device exceeds a certain threshold, the valve will release excess air or gas to prevent bursting or damage. **
