凸耳式（支耳式）双瓣止回阀、逆止阀、单向阀。
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
进口凸耳式双瓣止回阀 支耳式逆止阀主要特点design features
阀瓣关闭快速，水锤压力小 the valve clack closes quickly and the water hammer pressure is small
水平管道或垂直管道均可使用，安装方便 both horizontal pipe and vertical pipe can be used for convenient installation
流道通畅、流体阻力小 smooth flow passage and small fluid resistance
动作灵敏、密封性能好 sensitive action, good sealing performance
阀瓣行程短、关闭冲击力小 short disc stroke and small closing impact
整体结构、简单紧凑、造型美观 overall structure, *and compact, beautiful appearance
使用寿命长、可靠性高 long service life and high reliability
