进口轨道式球阀，无磨损轨道球面截断阀性能描述 Performance description

轨道式球阀（无磨损轨道球面截断阀）以其独特的结构，采用阀芯旋转分离式开启，机械施压密封的新技术设计，最突出的优点是密封面不产生磨擦，使用寿命长，操作扭矩低，即使介质中含有固体颗粒、泥沙、短纤维等杂质，流体介质高速集中冲刷密封体等苛刻的工况下，均可保持良好的密封 retz品牌 Orbital ball valve (non wear track spherical block valve) is designed with a new technology of rotating and separating valve core opening and mechanical pressure sealing, with its unique structure. Its most outstanding advantages are that the sealing surface does not produce friction, its service life is long, and its operating torque is low. Even if the medium contains impurities such as solid particles, sediment, short fibers, etc., and the fluid medium scours the sealing body at a high speed and concentration, it can maintain a good seal under harsh working conditions

进口轨道式球阀，无磨损轨道球面截断阀产品特性 Product characteristics

开关无磨损 The switch is not worn

球芯偏离阀座后再转动消除了阀座的磨擦，解决了传统球阀、闸阀、旋塞阀的阀座磨损问题 retz品牌  After the ball core deviates from the valve seat, the rotation eliminates the friction of the valve seat, and solves the wear problem of the valve seat of traditional ball valves, gate valves, and plug valves

抗磨阀芯硬密封面 Hard sealing surface of anti-wear valve element

球芯表面堆焊了一层硬质抛光密封面能保证非常苛刻工况下的密封性能 A layer of hard polished sealing surface is welded on the surface of the ball core to ensure the sealing performance under very harsh conditions

顶装式设计 Top mounted design

在系统卸压后，可在线检查和维修，使维护简单化 After the system is depressurized, it can be checked and repaired online to simplify maintenance

低扭距操作 Low torque operation

均可配小手轮（除非特太口径），并无需齿轮箱。因为球面截断阀密封面无摩擦，转动特别容易，这就意味着可以使用经济的驱动装置，同时能保证有足够的驱动器推力来开关阀门 It can be equipped with small handwheel (unless the diameter is too large), without gearbox. Because the sealing surface of the spherical block valve is frictionless, it is particularly easy to rotate, which means that an economical driving device can be used, and at the same time, sufficient driving force can be guaranteed to open and close the valve

最佳流动特性 Optimum flow characteristics

全通径和标准通径都有很高的Cv值，增强了泵的系统效率。并使磨蚀问题降为最低程度 Both full diameter and standard diameter have high Cv value, which enhances the system efficiency of the pump. And minimize the abrasion problem

双阀杆导向销 Double stem guide pin

硬性阀杆导槽与导销控制阀杆的升降与转动 The rigid valve stem guide groove and guide pin control the lifting and rotation of the valve stem

长寿命 Long life

当球芯倾离阀座时流体沿密封面360度将密封区域内的杂物冲洗干净 When the ball core is tilted away from the valve seat, the fluid will flush the sundries in the sealing area 360 degrees along the sealing surface

机械楔形密封 Mechanical Wedge Seal

阀杆下端的凸轮斜面提供一个机械的楔紧力以保证足够的密封比压 The cam bevel at the lower end of the valve rod provides a mechanical wedging force to ensure sufficient sealing specific pressure
