富林克对夹升降式止回阀亦称对夹升降式逆止阀、对夹升降式单向阀,特别适合于安装空间受限制的场合,对夹升降式止回阀采用短型结构尺寸和单阀瓣设计,相比传统的旋启式止回阀,该系列阀门具有无外泄露、可任意位置安装、密封性能好、线性震动小、压降小和零座圈磨损优势。
原理--
对夹升降式止回阀阀瓣沿着中心定位作升降运动,由于阀瓣的关闭行程短,并有弹簧加载,关闭速度快,可显著减少水锤现象。产品具有体积小、重量轻、动作灵敏、密封可靠、安装方便等特点,特别适合于安装空间受限制的场合采用。
特点-
1.动作灵敏,阀瓣关闭快速,行程短、关阀冲击力小
2.整体结构,具有结构短、体积小、质量轻。
3.流道通畅,流体阻力小;动作灵敏,密封性能好。
4.因速闭作用,可防止介质倒流,消除水锤作用强。
5.安装方便,可在水平、垂直两个方向的管路上安装。
6.阀板采用对偶板上加两个扭力弹簧的设计,可使阀板自行速闭。
7.因速闭作用,可防止介质倒流,消除水锤作用强;
