    • An insertable backflow preventer is presented. The backflow preventer is provided with a cylindrical housing. The housing has a flow transition zone, a proximal orifice/ball seat, a ball with a specific weight that equals or is close to the specific weight of the surrounding fluid, and a distal retaining screen. The housing can have a flange provided on the outside of the housing at one end to facilitate securing the valve in a pipe. The valve is self-cleaning, can be placed in any orientation in a pipe and has low hydraulic head-loss. The valve's unique cost-effective design provides for easy and relative quick installation, eliminates the need to reconfigure existing plumbing, and can be performance tested remotely. Properly installed, it can dramatically improve the security of, for example, potable water sources in a building or other context, and inasmuch as when installed it is not visible, it is tamper proof. The valve can be scaled to any size pipe or tube, and due to its internal flow dynamics is self cleaning. Multiple valves can be installed in series, and balls of varying specific weight can be used in each valve in such a series to allow for contexts where a range of fluids are sent through the same line, or to provide fail-safe operation in the event that contaminants change the specific gravity of the fluid.
    • 介绍了可插入防回流装置。 防逆流器设置有圆柱形壳体。 壳体具有流动过渡区域,近端孔/球座,具有等于或接近周围流体的比重的比重的球,以及远侧保持屏。 壳体可以在一端具有设置在壳体的外侧上的凸缘,以便于将阀固定在管道中。 阀门是自清洁的,可以放置在管道中的任何方向上,并具有低液压头损失。 阀门独特的经济高效的设计提供了简单和相对快速的安装,无需重新配置现有的管道,并可进行远程性能测试。 正确安装,可以显着提高建筑物或其他情况下饮用水源的安全性,并且由于安装时不可见,因此它是防篡改的。 阀可以缩放到任何尺寸的管道或管道,并且由于其内部流动动力学是自清洁的。 多个阀可以串联安装,并且可以在每个阀门中使用不同比重的球,这样一系列的阀可以允许通过同一管线传送一系列流体的情况,或在事件中提供故障安全操作 污染物会改变流体的比重。
