Abstract
A method of controlling the flow of a fluid in a pipe system includes controlling a valve in the pipe system, the valve including a valve body having an inlet, an outlet, and a body cavity, a gate 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, 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, moving the sync cam in a first direction to a front stop position; and moving the gate in the first direction to allow fluid to flow from the inlet to the outlet.
Claims20
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.

- moving the sync cam in a first direction to a back stop position, wherein the back stop position reduces the second gap;
- and
- moving the gate to restrict fluid from flowing from the inlet to the outlet.
