摘要： A chemical fluid valve transfer (e.g., load/unload) assembly is formed from a male valve assembly and a female valve assembly. The male valve assembly is fitted with a male connector which houses a chamber that is connected to a flush inlet line, and a flush outlet line, and a chemical transport line. The female valve assembly is fitted with a female connector which mates with the male valve assembly male connector for interconnecting the male valve and female valve assemblies, and fitted with a chemical transport line. Another aspect of the present invention is a method for transferring a chemical fluid between a tanker fitted with a female coupler and a fill/unload station fitted with a male coupler and hose assembly. This method involves the connecting of the tanker hose and the fill station hose with the valve assembly described above. Next, the male and female connectors and said chamber are purged with liquid or gaseous cleaning fluid admitted via the flush inlet flush line and withdrawn via the flush outlet line. One of the male valve assembly or the female valve assembly then is opened to permit the chemical fluid to enter into the chamber for withdrawal therefrom via the flush outline line for its sampling. Finally, the chemical fluid is transferred between the tanker and the fill station through the valve assembly.
摘要翻译： 化学流体阀传递（例如，装载/卸载）组件由阳阀组件和阴阀组件形成。 阳阀组件装有一个阳连接器，该阳连接器容纳连接到冲洗入口管线的一个室，以及一个冲洗出口管线和一个化学输送管线。 阴阀组件配有阴连接器，该阴连接器与阳阀组件公连接器配合，用于互连阳阀和阴阀组件，并配有化学输送管线。 本发明的另一方面是一种用于在装配有母耦合器的油罐车和装有阳联接器和软管组件的填充/卸载站之间转移化学流体的方法。 该方法涉及使用上述阀组件连接油罐软管和填充站软管。 接下来，阳，阴连接器和所述腔室被清洗通过冲洗入口冲洗管线通过冲洗出口管线排出的液体或气体清洁流体。 阳阀组件或阴阀组件中的一个然后被打开以允许化学流体进入腔室中，以通过冲洗轮廓线从其中取出用于其取样。 最后，化学液体通过阀门组件在油罐和加油站之间传送。
