(API,ASME,ANSI)进口美标止回阀性能说明 Function description

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 core is made into a "pin type", and the valve core can swing freely. The pressure loss is small, and the fluid is easy to flow. It can be used not only for horizontal piping, but also for vertical piping (flowing from bottom to top)

(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 for convenient 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 based hard alloy, with excellent wear resistance, corrosion resistance and scratch resistance

整体结构、简单紧凑、造型美观 Overall structure, simple and compact, beautiful appearance

内装式的销轴结构，减小外泄漏，使用可靠 The built-in pin structure reduces leakage and 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, the middle chamber of the valve adopts a self tightening sealing joint. The higher the medium pressure, the better the sealing performance
