The invention provides a device and method for preventing clamping stagnation of a brake pressure servo valve in an aircraft brake system, the device comprises a filter joint and a process oil filter, the filter joint is arranged on a pipeline between the brake pressure servo valve and a batcher, a filter screen is arranged in the filter joint, and the process oil filter is connected with the filter joint. The shape and size of the filter joint are designed according to the shape and size of the original brake pressure servo valve; and a process oil filter is arranged on a pipeline between the batcher and the inner brake wheel and the outer brake wheel. According to the method, through hydraulic oil cleaning and brake system testing, solid pollutants, especially abrasion particles generated in the running-in stage and accumulated hydraulic oil in a blind cavity of a brake device, in the brake system can be cleaned.

    本发明提供了一种防止飞机刹车系统内刹车压力伺服阀卡滞的装置及方法,装置中包括过滤接头和工艺油滤,在刹车压力伺服阀与定量器之间管路上设置过滤接头,所述过滤接头中设有滤网,过滤接头形状尺寸根据原刹车压力伺服阀外形和尺寸设计;在定量器与内刹车机轮和外刹车机轮之间管路上设置工艺油滤。本发明方法通过液压油清洗和刹车系统试验,能够实现对刹车系统中固体污染物进行清理,特别是磨合阶段产生的磨损颗粒和刹车装置盲腔内的积压液压油。
