Abstract

Valved coupling V can be connected into a two-line coolant flow path. V is adapted to be quickly connected into and disconnected from the flow path. To accomplish this, V is composed of two identical halves. Each contains two ports 1 and 2 that terminate on their inner ends at semispherical valve member or actuator 3. In the disconnected position, member 3 is turned so that its outer face is flush with the end of the associated half of V so that fluid can flow through the half as indicated by arrow a. Member 3 has a flow path 4, which, in the uncoupled position, extends between ports 1 and 2. Each member 3 also has stud 5 and hole 6. To couple the two halves together, the halves are aligned by placing studs 5 in the appropriate holes of the other half. Member 3 have tabs 7 that extend above the valve casing.

Coupling Valve

Valved coupling V can be connected into a two-line coolant flow path. V is adapted to be quickly connected into and disconnected from the flow path. To accomplish this, V is composed of two identical halves. Each contains two ports 1 and 2 that terminate on their inner ends at semispherical valve member or actuator 3. In the disconnected position, member 3 is turned so that its outer face is flush with the end of the associated half of V so that fluid can flow through the half as indicated by arrow a. Member 3 has a flow path 4, which, in the uncoupled position, extends between ports 1 and 2. Each member 3 also has stud 5 and hole 6. To couple the two halves together, the halves are aligned by placing studs 5 in the appropriate holes of the other half. Member 3 have tabs 7 that extend above the valve casing. When the halves are brought together, tabs 7 can be twisted 90 degrees until they abut stop shoulders. The twisting action causes each member 3 to rotate into the casing of the other half and provide an interlock for holding the joint together. When members 3 are rotated 90 degrees, flow paths 4 provide parallel flow paths through V.

The outer sealing surface of a member 3 is spherical. This allows 0-ring seals 8 incorporated in the valve body to each lie in a plane and still contact the member 3 in a circle surrounding flow path 4. Maintaining these seals in a plane eliminates their tendency to distort under pressure and thus reduces the chanc...
