Abstract:
A chemical fluid valve transfer assembly which comprises:(a) a male valve assembly having a selectively operable male valve and being fitted with a male connector which houses a chamber that is connected to a flush inlet line and a flush outlet line, and fitted with a chemical transport line that is in fluid communication with said chamber through said male valve; and(b) a female valve assembly having a selectively operable female valve and being fitted with a female connector which mates with said male valve assembly male connector for interconnecting said male valve and female valve assemblies, and fitted with a chemical transport line that is in fluid communication with said chamber through said female valve when said female valve assembly is mated with said male valve assembly;whereby when said male valve assembly and said female valve assembly are interconnected into a unitary assembly, said male and female connectors and said chamber can be cleansed of contaminants with liquid or gaseous cleaning fluid via said flush inlet with said flush outlet line while said selectively operable male and female valves both are selectively closed, and thereafter one of said male valve assembly or said female valve assembly can be selectively opened and the other valve assembly remain selectively closed to permit chemical fluid to enter into said chamber for withdrawal therefrom via said flush outline line for its sampling to determine chemical purity of said chemical fluid prior to being transferred, wherein said valve assemblies remain interconnected into a unitary assembly during the operations of cleansing, sampling, and transporting.
