Problems solved by technology
There are a large number of valve control devices / systems in the aircraft hydraulic system. Valves control the actions of downstream hydraulic components, such as controlling the start and stop of actuators, hydraulic motors and other actuators. When the valves work, the pressure of the hydraulic system often fluctuates, and in severe cases even causes Pressure shock occurs in the local hydraulic system, and hydraulic equipment and pipelines will be damaged due to fatigue after long-term operation
This not only increases the operating cost of the aircraft, but also directly affects the flight safety of the aircraft.

Description
technical field [0001] The invention belongs to the field of aviation equipment and relates to a pressure switch and a method for pipeline pressure monitoring. Background technique [0002] The hydraulic system provides hydraulic energy as power for aircraft flight control system, high-lift system, landing gear system and other systems, and is an indispensable system in modern large-scale military and civil aircraft. There are a large number of valve control devices / systems in the aircraft hydraulic system. Valves control the actions of downstream hydraulic components, such as controlling the start and stop of actuators, hydraulic motors and other actuators. When the valves work, the pressure of the hydraulic system often fluctuates, and in severe cases even causes Pressure shock occurs in the local hydraulic system, and hydraulic equipment and pipelines will be damaged due to fatigue after long-term operation. This not only increases the operating cost of the aircraft, but...
