Abstract

A valve assembly for a fluid flow management control and leak detection and conservation system, the valve assembly is positioned within a valve well and includes a cam block, valve liner, valve body, spring, shaft, and cover. The cam block, valve liner, and valve body each include a plurality of projections for cooperating with each other to allow rotation of the valve body while preventing rotation of the valve liner. The valve body and valve liner each include opposing pairs of openings for opening and closing the valve assembly. The valve assembly when in an open position allows fluid to flow through the openings of the valve body and valve liner and when closed the sidewall of the valve body presses firmly against the sidewall of the valve liner to form a seal therebetween ceasing all fluid flow.

Dependent claims

A fluid flow management control and leak detection and conservation system (10) comprising:

a manifold (124) defining an exterior inlet port (131), an exterior outlet port (142), a plurality of conduits (134, 137, 141) facilitating fluid communication between the exterior inlet port (131) and the exterior outlet port (142), and a valve well (133) positioned between the exterior inlet port (131) and the exterior outlet port (142) and in fluid communication with the plurality of conduits (134, 137, 141), the valve well (133) facilitating fluid communication between the exterior inlet port (131) and the exterior outlet port (142);
a valve assembly (11) positioned within the valve well (133), the valve assembly (11) including a cam block (20), a valve liner (30), a valve body (40), a shaft (12) passing through an upper bore (46) and a lower bore (47) of the valve body (40), and a bottom portion (12b) of the shaft (12) extending beyond the lower bore (47), a spring (13), and valve cover (70);
and
wherein the cam block (20) and valve liner (30) are positioned within the valve well (133) and do not rotate within the valve well (133) and wherein the shaft (12) is rotatable and causes the valve body (40) to rotate within the valve liner (30) between an open position and a closed position.

1 more element

A valve assembly (11) positioned in a valve well (133) of a fluid flow management control and leak detection and conservation system (10), the valve assembly (11) comprising:

a cam block (20) defining a plurality of cam projections (22) on a top end (20a), the cam projections (22) defining a sloped face (23) and a substantially vertical face (24);
a valve liner (30) defining a plurality of liner depressions (36) on a bottom surface (88) of a bottom end (30b) of the valve liner (30) configured to mesh and coincide with the plurality of cam projections (22), and the plurality of liner depressions (36) forming a plurality of liner projections (74) of equal magnitude on a top surface (87) of the bottom end (30b) of the valve liner (30);
a valve body (40) defining a plurality of valve body projections (49) configured to mesh and coincide with the plurality of liner projections (74);
a shaft (12) positioned through an upper bore (46) and a lower bore (47) of the valve body (40), and a bottom portion (12b) of the shaft (12) extending beyond the lower bore (47) of the valve body (40), the valve liner (30), and the cam block (20) and rotatable, the rotation of the shaft (12) causing the valve body (40) to rotate between an open position and a closed position;
a spring (13) positioned on the shaft (12) and seated above the valve body (40) to urge the valve body (40) down;
and
a valve cover (70) positioned and secured above the valve well (133).
