进口API美标止回阀 逆止阀 单向阀 美国RETZ瑞茨

　　retz工业/美国瑞茨，我们一直致力于流体控制领域的持续创新，始于2005……

　　(api,asme,ansi)进口美标止回阀性能说明 functiondeion

　　api美标止回阀（asme美式逆止阀）将圆盘状的阀芯一端制成“轴销形式”，阀芯可自由旋启的这样一种阀，其压力损失小，流体易于流动。不仅可用于水平配管，也可用于纵向配管（从下向上流动）retz one end of the disc shaped valve coreis made into a "pin type", and the valve core can swing freely. thepressure loss is small, and the fluid is easy to flow. it can be used not onlyfor horizontal piping, but also for vertical piping (flowing from bottom totop)

　　(api,asme,ansi)进口美标止回阀特点 features

　　水平或垂直管道均可使用，安装方便 horizontal or vertical pipes can be used forconvenient installation

　　密封面堆焊co基硬质合金，耐磨、耐蚀、抗擦伤性能优越 the sealing surface is welded with co basedhard alloy, with excellent wear resistance, corrosion resistance and scratchresistance

　　整体结构、简单紧凑、造型美观 overall structure, simple and compact, beautifulappearance

　　内装式的销轴结构，减小外泄漏，使用可靠 the built-in pin structure reduces leakageand is reliable in use

　　当压力为class1500lb时，阀门中腔采用自紧式密封结椅．介质压力越高，密封性能越好 when the pressure is class1500lb, themiddle chamber of the valve adopts a self tightening sealing joint. the higherthe medium pressure, the better the sealing performance
