进口凸耳式双瓣止回阀，支耳式逆止阀性能描述 Performance description
凸耳式双瓣止回阀采用短型结构,阀板为两个半圆，且采用弹簧强制复位，受压时阀门打开，无压力时在弹簧的作用下,阀瓣回座,阻止介质倒流，特别适合于安装空间受限制的场合采用The lug type double disc check valve adopts a short structure, with a valve plate of two semicircles and a spring forced reset. When under pressure, the valve opens, and when there is no pressure, the valve disc reseats under the action of the spring, preventing media backflow. It is particularly suitable for occasions with limited installation space
