(JIS)进口日标截止阀性能描述 Performance description进口不锈钢法兰截止阀原理.jpg

(JIS)日标钢制截止阀阀瓣采用锥形设计,密封面与介质成流线形,密封性能更好 RETZ (JIS) Japanese standard steel globe valve disc adopts conical design, and the sealing surface and medium form a flow line, with better sealing performance

可通过改变阀芯的形状,面朝着隔部上方阀座面按下阀芯,针对流体流向压下,对流体进行流量调节和开关控制 By changing the shape of the valve core, press the valve core towards the valve seat surface above the spacer, and press down according to the flow direction of the fluid to adjust the flow and control the switch of the fluid

阀杆调质及表面氮化处理,有良好的抗腐和抗摩擦性能 The valve rod is quenched and tempered and the surface is nitrided, with good corrosion resistance and friction resistance
