Sealing device between moving cable and aircraft airtight partition compartment

The invention belongs to the technical field of seal and relates to a sealing device between a moving cable and an aircraft airtight partition compartment. The sealing device comprises the cable (4) which moves inside and outside an aircraft cockpit, wherein the transverse section of the cable is round. The sealing device is characterized by further comprising an inner wear-proof elastic body (1), a base (2), a guide moving ball (3) and an outer wear-proof elastic body (5). The sealing device improves the sealing performance on the premise of guaranteeing movement of the cable, avoids that the aircraft cockpit directly communicates with the atmosphere through the sealing device, protects the aircraft cockpit against the pressure boost penalty and lowers the burden of an aircraft environment control system. 本发明属于密封技术领域，涉及种运动线缆与飞机气密隔断间的气密装置。它包括在飞机座舱内外运动的横截面为圆形的线缆(4)，其特征在于：还包括内耐磨弹性体(1)、基座(2)、导向运动滚珠(3)和外耐磨弹性体(5)。本发明提出了种运动线缆与飞机气密隔断间的气密装置，在保证线缆运动的前提下，提高了密封性能，避免了飞机座舱通过气密装置直接通大气，防止了飞机座舱出现增压代偿损失，减轻了飞机环控系统的负担。
