    Abstract: An automated irrigation purge system utilizes a pressure purge method of discharging compressed air from a reservoir through selected irrigation zones with feedback from pressure switches to determine when to open and close each zone valve. No programming or user interaction is required beyond starting the system. The system can operate with a wide variety of irrigation systems, with varying number of zones, pipe lengths, pipe diameters, number and variety of sprinkler heads or outlets, and terrain slope. The system tracks the pressure transition time from high pressure to low pressure for each zone as it is blown out. When the current transition time is within a specified range from the previous transition time, the system knows the water has been sufficiently purged from that zone. The purge system can protect the irrigation system from high-pressure conditions, handle multiple error conditions, and maintain water valve settings during power loss.

The self-cleaning feature may be integrated into the valve, for example, by removing a “cut-out” portion between sealing surfaces of ports. These cut-out portions may create vortices that might clean debris from the sealing surfaces. The cut-outs may also provide a place for debris to collect-keeping it away from the sealing surfaces. In addition, or as an alternative to cut-outs, some other type of mechanism, such as sealing members designed to disturb flow to sweep away debris near a sealing surface or helical grooves (rifling) formed in the ports, may also be used to promote self-cleaning.

  • Publication number: 20110136700
    Abstract: The present invention includes a method for inhibiting hydrate formation blockage in a flow line used to transport hydrocarbon containing fluids. Water is added to a hydrocarbon containing fluid to produce a water cut enhanced hydrocarbon containing fluid. Salt may be added to the hydrocarbon containing fluids as well. Hydrate formation blockage is inhibited from forming within the flow line by the addition of the water and/or the salt. Sufficient water may be added such that the hydrocarbon containing fluid is converted from a water in oil emulsion to a water continuous emulsion. A system for preventing the formation of hydrate blockage in conduits is also provided. The system includes a flow line for transporting a hydrocarbon containing fluid and a water injection conduit fluidly connected to the flow line to add water to the flow line to increase the water cut of a hydrocarbon containing fluid flowing through the flow line.

  • Publication number: 20110073194
    Abstract: A self cleaning valve assembly includes a valve body having an internal valve cavity. A cylinder member received in the valve cavity has a first sealing surface and a cylinder wall, and divides the valve cavity into a liquid-free cavity portion and a flow cavity portion. A spindle includes a spindle body contacting the first sealing surface to continuously prevent pressurized fluid in the flow cavity portion from entering the liquid-free cavity portion. A spindle piston end has a wiper member in a receiving groove frictionally contacting the cylinder wall. A handle pinned to the valve assembly directly contacts the piston end. Handle rotation displaces the spindle from a valve closed to a valve open position permitting pressurized fluid flow into the flow cavity portion. The wiper member wipes a contaminant off the cylinder wall and further prevents contaminant entrance into the liquid-free cavity portion.
