    • Disclosed is a fluid dispensing system for precisely controlling the mixing of a first fluid (i.e., a diluent such as water) with a second fluid (i.e., a concentrate) at a mixing point within the fluid dispensing system. A valve is positioned in the dispensing system along the line of supply of the second fluid upstream of the mixing point, such valve being simultaneously actuated through application of positive and/or negative pressure to allow the second fluid to flow through the valve. The application of positive and/or negative pressure is generated from the first fluid to be dispensed by the system and mixed with the second, such that the termination of flow of the first fluid immediately terminates flow of the second fluid to ensure proper mixing of the two fluids in the final solution, thus preventing inadvertent leakage of the second fluid or collection of the second fluid within the flow system which may become subject to spoilage or contamination.
    • 公开了一种流体分配系统,用于在流体分配系统内的混合点处精确地控制第一流体(即,稀释剂例如水)与第二流体(即浓缩物)的混合。 沿着混合点上游的第二流体的供应线将阀定位在分配系统中,通过施加正压力和/或负压同时致动阀,以允许第二流体流过阀。 正压力和/或负压的应用由系统要分配的第一流体产生并与第二流体混合,使得第一流体的流动的终止立即终止第二流体的流动,以确保第二流体的适当混合 最终溶液中的两种流体,从而防止流体系统内第二流体或第二流体的收集物无意泄漏,该流体系统可能变质腐蚀或污染。
