Abstract

A low pressure drop quick-disconnect valve, consisting of two halves, is provided. The first half 10 is permanently attached to the unit, such as a cold plate, which is to receive the liquid. The mating or second unit 12, which has the inlet and outlet hoses connected thereto, is adapted for mating with the first half of the valve 10. The first half 10 of the valve contains protruding members 14 and 16 which mate with corresponding openings in valve half 12. Valve halves 10 and 12 contain valve cores 18 and 20 respectively. These rotary valve cores each contain an opening indexed with the inlet and outlet flow paths. The valve cores 18 and 20 are operated by the handles 22 and 24, respectively.

Low Pressure Drop Quick Disconnect Valve

A low pressure drop quick-disconnect valve, consisting of two halves, is provided. The first half 10 is permanently attached to the unit, such as a cold plate, which is to receive the liquid. The mating or second unit 12, which has the inlet and outlet hoses connected thereto, is adapted for mating with the first half of the valve 10. The first half 10 of the valve contains protruding members 14 and 16 which mate with corresponding openings in valve half 12. Valve halves 10 and 12 contain valve cores 18 and 20 respectively. These rotary valve cores each contain an opening indexed with the inlet and outlet flow paths. The valve cores 18 and 20 are operated by the handles 22 and 24, respectively. The handles when pushed to the open position turn the valve core such that the openings therethrough are in line with the inlet and outlet flow paths. It should be noted that the handles 22 and 24 are operated as a unit such that the valve cores 18 and 20 are simultaneously operated, cutting off the liquid flow at the two valve core points. When connected, a locking tab 26 on one half 10 fits into opening 28 on the other half.

Fig. 2, a sectional view of the quick-disconnect valve, shows the locking handles in the open position which prevents the locking tabs 26 from being opened or unlocked. To actually detach the locking tab 26, it is necessary to move the handles to the closed position. This is a fail-safe feature preventing the ...
