Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of machining technology, and relates to a machining tool of a cabin pressure regulator, in particular to a cabin exhaust valve disc straight wall hole making device. BACKGROUND

[0002] The disc is a key component of the cabin exhaust valve, and its main function is to control the air flow and discharge volume in the cabin by opening and closing. It is a key component to realize the pressure regulation and maintain the stable air pressure in the cabin. Specifically, when the air pressure in the cabin needs to be reduced, the disc of the cabin exhaust valve opens to allow the air in the cabin to pass into the valve and be discharged to the outside of the aircraft. Conversely, when the air pressure in the cabin needs to be increased or maintained, the disc closes to prevent outside air from entering the cabin or limit the discharge of air in the cabin. This way of controlling air flow by opening and closing the disc allows the cabin exhaust valve to accurately regulate the air pressure in the cabin, ensuring that it fluctuates within a suitable range, thereby ensuring the comfort and safety of passengers and crew. In addition, the disc of the cabin exhaust valve also needs to have good sealing performance to ensure that it can effectively prevent gas leakage in the closed state, thereby further ensuring the stability of the air pressure in the cabin. In summary, the disc of the cabin exhaust valve plays a crucial role in the aircraft environmental control system and is one of the important components to ensure the safety of aircraft flight and passenger comfort.
