詳細介紹
1、特點The characteristics of
旋啟式止回閥是控制管道內(nèi)介質(zhì)單向流向的閥門,用來防止管路中的介質(zhì)倒流。適用各種管路的各種壓力、溫度和介質(zhì)下控制接通或截斷管路介質(zhì)的啟閉裝置;依靠閥瓣自重和流體壓差實現(xiàn)自動阻止流體倒流。適用介質(zhì)為: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.
