進口Y型止回閥，擋板式逆止閥原理慨述 Principle description

Y型止回閥（擋板式逆止閥）主要用于介質（水、氣）單向流動的管道上 RETZ Y-type check valve (flapper check valve) is mainly used on pipelines with one-way flow of medium (water)

只允許介質（水）向一個方向流動，以防止發(fā)生介質（水）倒流引起事故，安裝單向止回閥，解決水表空轉現(xiàn)象  The medium (water) is only allowed to flow in one direction to prevent accidents caused by medium (water) backflow. A one-way check valve is installed to solve the problem of water meter idling

工作條件 Working conditions

口徑范圍：DN15至DN50  Diameter range: DN15 to DN50

工作壓力:  16bar  Working pressure: 16bar

閥門材質：黃銅或不銹鋼 Valve material: brass or stainless steel

工作溫度：≤180℃ Working temperature: ≤ 180 ℃

可垂直水平安裝，垂直安裝介質必須有下向上 The valve can be installed vertically and horizontally, and the vertical installation medium must be downward and upward

閥體一體成型，抗壓防爆，壁厚均勻，只進不出 The valve body is integrally formed, anti pressure and explosion-proof, with uniform wall thickness, which can only enter and exit

全流量、壓損小、防水錘 Full flow, small pressure loss, waterproof hammer

閥瓣有彈性,密封性能好，啟閉迅速，不易堆積雜務 The valve clack is elastic, with good sealing performance, quick opening and closing, and it is not easy to accumulate chores
