Abstract
Valves include a valve body having an inner surface and an outer surface, the inner surface and the outer surface defining an inlet, an outlet, and a body cavity between the inlet and the outlet; a gate movably coupled to the valve body and moveable over a portion of the valve body at least partially between the inlet and the outlet, the gate including a cam stop; and a drive assembly, the drive assembly including a drive shaft and a sync cam, the sync cam of the drive assembly movably positioned on the drive shaft and slidably positioned relative to the cam stop.
Claims33
A valve comprising:
- a valve body having an inner surface and an outer surface, the inner surface and the outer surface defining an inlet, an outlet, and a body cavity between the inlet and the outlet;
- a gate movably coupled to the valve body and moveable over a portion of the valve body at least partially between the inlet and the outlet, the gate including a cam stop;
- and
- a drive assembly, the drive assembly including a drive shaft and a sync cam, the sync cam of the drive assembly movably positioned on the drive shaft and slidably positioned relative to the cam stop, the sync cam including at least one load balancing mechanism.
A method of syncing a valve comprising:
- accessing a valve including
- a valve body having an inner surface and an outer surface, the inner surface and the outer surface defining an inlet, an outlet, and a body cavity between the inlet and the outlet;
- a gate coupled to the valve body and moveable over a portion of the valve body at least partially between the inlet and the outlet, the gate including a first cam stop and a second cam stop;
- and
- a drive assembly, the drive assembly including a first sync cam movably coupled to a first drive shaft and a second sync cam movably coupled to a second drive shaft, the first sync cam slidably positioned relative to the first cam stop, the second sync cam slidably positioned relative to the second cam stop, the first sync cam including a first front flange and a first back flange, the second sync cam including a second front flange and a second back flange;
- moving the gate to a front stop position, wherein the front stop position includes at least one of the first front flange and the second front flange in contact with at least one of the first cam stop and the second cam stop;
- aligning the first front flange in the front stop position to contact the first cam stop and the second front flange in the front stop position to contact the second cam stop;
- moving the gate to a back stop position, wherein the back stop position includes at least one of the first back flange and the second back flange in contact with at least one of the first cam stop and the second cam stop;
- and
- aligning the first back flange in the back stop position to contact the first cam stop and the second back flange in the back stop position to contact the second cam stop.
A method of controlling the flow of a fluid in a pipe system comprising:
- controlling a valve in the pipe system, the valve including
- a valve body having an inner surface and an outer surface, the inner surface and the outer surface defining an inlet, an outlet, and a body cavity between the inlet and the outlet;
- a gate movably coupled to the valve body and moveable over a portion of the valve body at least partially between the inlet and the outlet, the gate including a cam stop;
- and
- a drive assembly, the drive assembly including a drive shaft and a sync cam on the drive shaft, the sync cam of the drive assembly including a front flange and a back flange, the sync cam movably positioned on the drive shaft of the drive assembly and slidably positioned relative to the cam stop, a first gap defined between the front flange and the cam stop, a second gap between the back flange and the cam stop, the drive assembly including at least one load balancing mechanism;
- moving the sync cam in a first direction to a front stop position, wherein the front stop position reduces the first gap;
- and
- moving the gate in the first direction to allow fluid to flow from the inlet to the outlet.
