　　进口不锈钢法兰止回阀用途慨述 Overviewof use

　　不锈钢法兰止回阀（304,316白钢逆止阀）是具有常时保持流体固定流向,防止倒流功能的阀。阀芯在流体压力的作用下被推开，呈流通状，但倒流时，阀芯在背压作用下与阀体的阀座密切接触，防止倒流 The stainless steel flange check valve (304316 white steel checkvalve) is a valve with the function of maintaining a fixed flow direction offluid and preventing backflow. The valve core is pushed away under the actionof fluid pressure, in a flowing state. However, during backflow, the valve coreis in close contact with the valve seat under the action of back pressure toprevent backflow

　　进口不锈钢法兰止回阀结构 structure

　　升降式止回阀结构特点 Structuralfeatures of lift check valve

　　属于将截止阀上的阀杆、手柄、其它开闭操作部分卸下，加盖后形成的构造。流体阻抗较大，主要是较小口径的产品 It belongs to the structure formed after removing the valve stem,handle and other opening and closing operation parts on the stop valve andcapping them. Large fluid impedance, mainly products with small diameter

　　动作灵活可靠 . 密封性能优良 Flexible and reliableoperation, excellent sealing performance

　　设计抗震弹簧:不锈钢 Design anti-seismic spring:stainless steel

　　jing确导向阀瓣，动作灵敏、密封性能好 Precise guide disc, sensitive action and good sealing performance

　　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

　　旋启式止回阀结构特点 Structuralfeatures of swing check valve

　　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）One end of the disc shaped valve core is made into a "pintype", 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)

　　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

　　动作灵敏、密封性能好 Sensitiveaction, good sealing performance

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

　　使用寿命长、可靠性高 Long servicelife and high reliability
