    • A dispensing device (10) for dispensing a measured amount of a chemical (60) into a fluid piping system including a cap member (24) having a fluid inlet port (33) and a fluid outlet port (34) between which is a tubular flow conduit (28). The cap member (24) also includes bypass and control members (44), which align with an inlet passageway (36) and an outlet passageway (42) in the cap member (24). Fluid flows into the cap member (24) through the inlet port (33). The tubular flow conduit (28) has the inlet passageway (36) therein to divert a portion of the fluid passing through the system into a canister (11) operatively connected to the cap (24). A container (16) is disposed within the canister (11) containing the chemical (60), which is partially dissolved by fluid introduced into the container (16) to create a use solution. The use solution passes out of the canister (11) through the outlet passageway (42) in the tubular flow conduit (28) located downstream from the inlet passageway (36) and is reintroduced into the fluid system to flow out of the outlet port (34). The bypass and control members (44) may be used in variable positions to control and meter the amount of use solution being dispensed.
    • 一种用于将测量量的化学物质(60)分配到包括具有流体入口(33)和流体出口(34)的盖构件(24)的流体管道系统中的分配装置(10),其间是管状 流动管道(28)。 盖构件(24)还包括与帽构件(24)中的入口通道(36)和出口通道(42)对准的旁路和控制构件(44)。 流体通过入口(33)流入盖件(24)。 管状流动管道(28)在其中具有入口通道(36),以将通过系统的一部分流体转移到可操作地连接到盖子(24)的罐(11)中。 容器(16)设置在容纳化学物质(60)的罐(11)内,该化学物质被引入容器(16)中的流体部分地溶解以产生使用溶液。 使用溶液通过位于入口通道(36)下游的管状流动管道(28)中的出口通道(42)从罐(11)排出,并被重新引入流体系统以流出出口 34)。 旁路和控制构件(44)可以用于可变位置以控制和计量正在分配的使用溶液的量。
