Winding head pressure self-protection device

The utility model relates to the field of spinning, in particular to a winding head pressure self-protection device. Comprising a compressed air pipeline, and a quick connector, a check valve and a direct connector are sequentially connected to the compressed air pipeline. The technical problem to be solved by the utility model is to provide the pressure self-protection device for the winding head, which prevents compressed air from losing to the outside and avoids economic loss caused by shutdown of equipment. According to the utility model, the check valve is arranged on the compressed air pipeline, so that compressed air only flows to each winding machine from the compressed air conveying device, and part damage caused by outward running of the compressed air due to shutdown is prevented. 本实用新型涉及纺丝领域，尤其涉及一种卷绕头压力自保装置。包括压缩空气管道，所述压缩空气管道上依次连接有快速接头、止回阀和直接接头。本实用新型要解决的技术问题，在于提供一种卷绕头压力自保装置，防止压缩空气往外部流失，避免设备因停机造成的经济损失。本实用新型在压缩空气管道上设置止回阀，使压缩空气仅从压缩空气输送装置流向各卷绕机，防止因停机造成压缩空气往外跑产生的零件损坏。
