The invention provides a temperature and pressure detection device suitable for an undercarriage buffer. The temperature and pressure detection device comprises a signal processing box and two temperature and pressure one-way valves; temperature and pressure signals collected by temperature and pressure composite sensors in the temperature and pressure one-way valves are processed through the signal processing box and output in a digital signal mode; and the temperature and pressure of the high-pressure cavity part and low-pressure cavity part of the undercarriage buffer are detected through the two temperature and pressure one-way valves respectively, and the detected temperature and pressure are fed back to an airplane management computer in a signal mode through an electric connector. One temperature and pressure composite sensor is added, the original inflation pressure maintaining function of the one-way valves is kept, and temperature and pressure detection of media in a productcan be achieved. The temperature and pressure detection device has the advantages of compact structure, small product size, light weight, reliable and effective performance and high universality, andcan be conveniently machined into various specifications.
Description
technical field [0001] The invention relates to the field of aircraft landing gear systems, in particular to a temperature and pressure detection device suitable for landing gear buffers. Background technique [0002] Most of the aircraft currently in use, when the maintenance personnel check the pressure of the buffer part of the landing gear of the aircraft, they need to connect an external pressure gauge to the buffer part for detection or use a special inflation device for necessary inflation. , this detection method is labor-intensive and time-consuming. Therefore, taking necessary rapid detection measures is beneficial for the maintenance personnel to know the pressure and temperature of the aircraft landing gear buffer in time, so as to carry out the maintenance of the aircraft landing gear at any time, and at the same time improve the safety and usability of the aircraft. Through a temperature and pressure detection device suitable for landing gear buffers, rapid te...
