Abstract

Gas and particulate contaminants can be prevented from entering high purity liquids during pumping operations by use of a special design quick connect coupling system. The coupling system also reduces flow restrictions and enhances the vacuum required for pumping operations, and it can be completely disassembled for cleaning and repair.

Quick Connect System

Gas and particulate contaminants can be prevented from entering high purity liquids during pumping operations by use of a special design quick connect coupling system. The coupling system also reduces flow restrictions and enhances the vacuum required for pumping operations, and it can be completely disassembled for cleaning and repair.

Figure 1 shows a cross-section through the coupling system as installed on a liquid supply container. Connect housing 1 is connected to the top surface 2 of the container in a fixed relationship. The housing 1 is provided with attachment means 3 and gasket seal seat 4 for leak-proof connection of pumping apparatus (not shown). Housing 1 further contains a cavity 5 which is opened at end 6 and has perforated openings at its other end 7.

A barrel siphon housing 8 is fixedly attached to housing 1 at end 7 with gasket sealing means 9 optionally sealing housing 8 to housing 1. Housing 8 is submerged in the liquid to be pumped. A movable piston 10 with connecting plunger stem 11 is movably positioned through end 7 of housing 1. Piston 10 is comprised of through perforations such that when spring 12 expands to force said piston against end 7, said perforations are so arranged so as to form a seal therebetween.

In operation, in its sealed condition piston 10 is held closed against surface 7 by spring 12 so that respective perforations are offset and no liquid and/or gas can enter the container. Upon insertion of pump...
