The invention is applicable to the technical field of aerospace, and provides a bionic glue pressing groove for pneumatic sealing, which comprises a metal valve, and is characterized by further comprising a glue pressing groove and bionic grooves, a plurality of annular bionic grooves arranged up and down are arranged on the inner circumferential surface of the glue pressing groove, and the bionic grooves are arranged in the metal valve. Or a plurality of linear bionic grooves which are distributed in a circumferential array are formed in the inner circumferential surface of the glue pressing groove. By means of a new surface technical means, the roughness of the metal surface is improved, meanwhile, the consistency of the roughness of the rubber bonding face can be controlled, then the bonding strength and sealing efficiency of pressure injection rubber of the sealing face are enhanced, the service life of a workpiece is prolonged, and the service life of the workpiece is prolonged. Therefore, the reliability of the pneumatic sealing element in the sealing element cooling and heating alternation aggravation caused by the rapid climbing and descending frequency increase of the airplane under the new outline training is ensured.

    本发明适用于航空航天技术领域,提供了一种气动密封用仿生压胶槽,包括金属活门,其特征在于,还包括:压胶槽和仿生槽,压胶槽的内周面上设有若干呈上下排列的环形仿生槽,或压胶槽的内周面上设有若干呈圆周阵列分布的一字形仿生槽。本发明通过新的表面技术手段在提高金属表面粗糙度的同时,能够控制橡胶粘接面粗糙度的一致性,进而增强密封面压注橡胶的粘接强度与密封效能,延长了工件寿命,从而保证了新大纲训练下飞机迅速爬升与下降频次增加导致密封件冷热交替加剧中气动密封件的可靠性。
