retz进口y型止回阀，挡板式逆止阀采用挡板式结构，流道通畅、流体阻力小，用于防止管路中介质倒流的单向阀 y-type check valve, baffle type check valve adopts a baffle type structure, with smooth flow channels and low fluid resistance. it is a one-way valve used to prevent medium backflow in the pipeline
进口y型止回阀 挡板式逆止阀 y型弹簧式单向阀原理慨述 principle description
y型止回阀（挡板式逆止阀）主要用于介质（水、气）单向流动的管道上 retz y-type check valve (flapper check valve) is mainly used on pipelines with one-way flow of medium (water)
只允许介质（水）向一个方向流动，以防止发生介质（水）倒流引起事故，安装单向止回阀，解决水表空转现象 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
主要特点design features
可垂直水平安装，垂直安装介质必须有下向上 the valve can be installed vertically and horizontally, and the vertical installation medium must be downward and upward
阀体一体成型，抗压防爆，壁厚均匀，只进不出 the valve body is integrally formed, anti pressure and explosion-proof, with uniform wall thickness, which can only enter and exit
全流量、压损小、防水锤 full flow, small pressure loss, waterproof hammer
阀瓣有弹性，密封性能好，启闭迅速，不易堆积杂务 the valve clack is elastic, with good sealing performance, quick opening and closing, and it is not easy to accumulate chores
