温州森明阀门管件有限公司 Wenzhousenminvalvepipe fittingco.,ltd. 卫生级止回阀 Sanitary Check Valve 应 用 : 该类型止回阀用于不锈钢管道系统内, 以达到防止流体回流的目的 Application: This type of check valves are used to stainless steel pipe system, in order to prevent the fluid flowing back. 工作原理 : 止回阀是指依靠介质本身流动而自动开 闭阀瓣的一类阀门, 当阀杆下部的压力超过阀杆上面的压力以及弹簧力时, 止回阀阀瓣就会开启 ; 当阀杆上下压力平衡时, 止回阀就会关闭, 从而达到介质在管道的单向流动, 阻止液体的倒流, 防止事故发生 Work Principle: Check valve is a type of valve which open or close the valve disc rely on the medium flow itself. The check valve disc will open when the pressure of stem bottom exceed the stem above and the spring.the check valve disc will close when the two pressure are equalled. So that the flow goes one way in the pipeline,and prevent the fluid flowing back,avoid the accidents. 材 料 : 钢制部件 : 不锈钢 304 不锈钢 316L 密封圈 : 硅橡胶 (VMQ) 氟橡胶 (FPM) 三元乙丙 (EPDM) Material: steel parts: 304 stainless steel, stainless steel 316L. Seal: silicone rubber Material (VMQ) fluoroelastomer (FPM),EPDM) 技术数据若止回阀被安装在一根垂直的管道内, 开启阀门所需的压力大约为 6Kpa, 最大输送物料压力为 1000Kpa, 使用温度范围为 -10-140 Technical Data: If the check valves are installed in a vertical pipe, it nedd approximately equal pressure 6Kpa to open. Maximum pressure for conveying material is 1000Kpa,.Using temperature scope for - 10-140. 134
