    • A backflow prevention assembly for global use with dispensers requiring a variety of backflow prevention devices based on regulatory standards is provided. The assembly includes a housing comprising first and second housing members and including quick connector attachments extending therefrom. The quick connector attachments are non-threaded members configured to be attached to the various measurement and types of connections found throughout the world. A cover is provided for venting purposes to reduce the backflow siphoning forces or pressure, which causes the backflow of a product chemistry. Furthermore, a backflow prevention device is configured to be fluidly coupled to the housing of the present invention to provide for one way flow and the prevention of backflow of a product chemistry into a water supply. The flow control may be selected based on the regulatory standards of the location used.
    • 本发明提供了一种用于全球使用的防回流组件,其中分配器需要基于监管标准的各种防回流装置。 组件包括壳体,该壳体包括第一和第二壳体构件,并且包括从其延伸的快速连接器附件。 快速连接器附件是非螺纹构件,其被配置为附接到遍及世界各地的各种测量和连接类型。 提供了用于排气目的的盖以减少回流虹吸力或压力,这导致产品化学反流。 此外,防逆流装置被配置为流体地联接到本发明的壳体,以提供单向流动并防止产品化学物质回流到供水中。 流量控制可以基于使用的位置的管理标准来选择。
