Appl. No.:

12/407387

Inventors:

Mark Zeck - Snyder TX, US

Assignee:

Sentry Equipment Corp. - Oconomowoc WI

International Classification:

C10J 1/28
G05D 11/00

US Classification:

48195, 48190, 481273, 137 9, 137 98, 13786141, 137605, 137 3, 13710119, 13710121, 137606, 137607, 137551, 13786112, 700266, 261DIG 17, 261 76, 428905

Abstract:

A system is shown for injecting a chemical, such as an odorant, from a chemical supply into a fluid containing system such as a natural gas pipeline or an LPG pipeline. A tank of odorant is maintained at a pressure above ambient, but below the pressure of the pipeline. An injection conduit communicates the odorant tank with the pipeline. A hydraulic pressure booster is located in the injection conduit for pressurizing the chemical to a pressure above that of the pipeline, the hydraulic booster having a first side which communicates with the chemical in the injection conduit and another, isolated side which is exposed to hydraulic pressure but which is isolated from the chemical being injected. A flow control valve may be located within the injection conduit for metering chemical to be injected into the pipeline.

Abstract:

A method for injecting a chemical, such as an odorant, from a chemical supply into a fluid-containing system such as a natural gas or an LPG pipeline. A tank of odorant is maintained at a pressure above ambient, but below pipeline pressure. An injection conduit communicates the odorant tank with the pipeline. A hydraulic pressure booster is located in the injection conduit for pressurizing the chemical to a pressure above that of the pipeline. Flow-control apparatus located within the injection conduit for metering chemical to be injected into the pipeline is either (a) drip-style metering valve adjustable between a drop-wise setting and a steady-flow setting or (b) a pair of valves one of which is a flow valve allowing larger volumes to be injected and the other which is a drop-wise flow valve for metering smaller volumes of the chemical.

Assignee:

Y-Z Industries Sales, Inc. - Snyder TX

International Classification:

F04B 902

US Classification:

417383

Abstract:

The present invention discloses a modular diaphragm cartridge for use with a pump assembly. A cartridge body defines an interior chamber into which a piston is slidably connected. A spring biases the piston against a diaphragm placed over the end of the cartridge body to enclose the interior chamber. An end cap which threadedly engages the cartridge body to enclose the diaphragm between the end cap and body. The modular diaphragm cartridge may be removed from a pump housing as a single unit without the need for keeping track of multiple pieces. The present invention further discloses a modular inlet valve assembly, outlet valve assembly and plunger seal/guide cartridge.

International Classification:

F04B 2100
F04B 3502

US Classification:

417 63

Abstract:

A fluid pump for displacing a small, precise volume of fluid for each pump stroke, particularly where the fluid to be displaced is a liquid containing dissolved gas. The precise volume of fluid to be displaced is adjustable to any selected amount up to the full displacement of the pump. The pump has instrumentation that indicates a seal failure within the pump, thus allowing for maintenance on the pump before a total failure. This instrumentation results in increased safety when the pump is used to inject odorant into a natural gas pipeline or in other precision chemical injection applications.

International Classification:

G05D 1113

US Classification:

13710125

Abstract:

A system for injecting chemicals, e. g. , odorants, from a chemical supply into a gas pipeline includes three primary components, a pump for injecting the odorant, a metering device, and a programmable controller. The controller is preferably powered by a solar panel to facilitate use of the system in remote areas for long periods of time. A removable data carrier, such as a memory module, is connected to the controller to collect odorant system event data. The data carrier is removable from the controller and the data therein may be downloaded into an auxiliary audit computer for generation of summary audit reports. The system precisely monitors how much odorant is used per pump stroke and insures that the odorant injection rate remains constant irrespective of environmental or equipment variations which might otherwise cause inaccuracies in the measurement of odorant usage data and/or the fluctuation of the odorant injection rate.
