1、特点The characteristics of

旋启式止回阀是控制管道内介质单向流向的阀门，用来防止管路中的介质倒流。适用各种管路的各种压力、温度和介质下控制接通或截断管路介质的启闭装置；依靠阀瓣自重和流体压差实现自动阻止流体倒流。适用介质为：水、油品、蒸汽等.Swing check valve, one-way flow of media is to control the pipe valve is used to prevent the backflow medium pipeline. Apply to all sorts of all sorts of pipeline pressure, temperature and medium under control through or truncation pipeline medium lifting device; Rely on the disc self-respect and fluid pressure differential automatically prevent fluid backflow. Applicable medium: water, oil, steam, etc.
