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 pair of drive lines, each drive line having a drive shaft, a first drive line of the pair of drive lines including a sync cam, the sync cam of the first drive line movably positioned on the drive shaft of the first drive line and positioned relative to the cam stop.
Claims20
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 pair of drive lines, each drive line having a drive shaft, a first drive line of the pair of drive lines including a sync cam, the sync cam of the first drive line movably positioned on the drive shaft of the first drive line and positioned relative to the 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 pair of drive lines, each drive line having a drive shaft, a first drive line of the pair of drive lines including a sync cam, the sync cam of the first drive line movably positioned on the drive shaft of the first drive line and positioned relative to the cam stop, a first gap defined between a front flange of the sync cam and the cam stop, a second gap defined between a back flange of the sync cam and the cam stop;
- 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.
