摘要
呼气膜片,为薄壁（0.2 ～ 0.3mm）橡胶件,自身精度要求高,广泛应用于各类面罩上的呼气活门机构中,使它能在高空处于供氧状态下,是用于保障飞行员正常呼吸的重要零件.膜片的厚度及精度,是决定其氧调试验性能的主要因素.该项目通过对氧调参数呼气膜片,进行外观与参数的工艺性分析、量化型腔尺寸及改进模具结构,提高了产品的稳定性及试验性能的合格率.
Breath diaphragm, thin （0.2 - 0.3）mm rubber parts, its high precision, the exhalation valve mechanism is widely used in all kinds of mask on the face, can make it high in the air in the oxygen supply condition is used for the important parts of security pilot normal breathing. Diaphragm thickness and accuracy, is the main factor to determine the oxygen transfer test performance. The project through the oxygen breath diaphragm adjustable parameter, analysis, process of appearance and parameters for the quantification of cavity size and improvement of mold structure, improve the qualified rate of stability and performance test of the product.
