Abstract
A kit for constructing a de-aerator that includes a concentrator is adapted to be connected to a standard pipe coupling. The concentrator is inserted in the path of liquid conveyed through the pipe coupling for aggregating gas, and directing the gas to a cavity. The cavity is encased by the fitting which is a vertical, cylindrical sheath with one end adapted to be inserted into standard pipe couplings, and the other end adapted to be connected with the cap. The cap includes a vent adapted to open and shut in response to lowering and raising of the level of the liquid in the cavity below/above a threshold, respectively.

A kit for assembling a de-aerator for removing gas from a liquid distribution system comprising:
- a cylindrical fitting having first and second ends, the first end being adapted to be inserted into a connector of a standard T-coupling having an unobstructed fluid flow path between an inlet connector and an outlet connector thereof, and connected to the coupling in a fluid-tight seal;
- a cap adapted to be connected to the second end of the fitting in a fluid-tight seal;
- a valve with a valve stein connected to a float for selectively closing the valve when the liquid rises above a predetermined level in the fitting, and for selectively opening the valve when the liquid in the fitting is displaced below the predetermined level by the gas;
- and
- a gas concentrator adapted to extract gas from the liquid flowing through the standard T-coupling, the gas concentrator being directly received in the unobstructed fluid flow path of the coupling, beneath the float.
A method of removing gas suspended in a liquid conveyed through a liquid distribution system, comprising steps of:
- installing a standard T-coupling in a run of pipe in the liquid distribution system, so that one connector of the T-coupling is in a vertical orientation and liquid in the liquid distribution system flows through an unobstructed flow path between an inlet connector and an outlet connector of the T-coupling;
- securing a fitting to the vertically oriented connector, the fitting having a first end that is adapted to be received in the connector and a second end that is adapted for the connection of a cap in a fluid-tight seal;
- inserting a gas concentrator through the fitting directly into the unobstructed flow path of the coupling;
- and
- connecting the cap to the second end of the fitting, the cap supporting a valve to permit gas accumulated by the gas concentrator to escape from the fitting when a certain volume of gas has been accumulated in the fitting, while inhibiting the liquid from escaping from the liquid distribution system.
A kit for a de-aerator for removing gas from a liquid distribution system used for radiant heating, comprising:
- a cylindrical fitting having first and second ends, the first end being adapted to be inserted into a connector of a standard T-coupling, and soldered to connector, the T-coupling having an unobstructed fluid flow path between an inlet connector and an outlet connector thereof;
- a cap adapted to be connected to the second end of the fitting in a fluid-tight seal, the cap supporting a valve with a valve stem connected to a float for selectively closing the valve when the liquid rises above a predetermined level in the fitting, and for selectively opening the valve when the liquid in the fitting is displaced below the predetermined level by the gas;
- and
- a gas concentrator adapted to extract gas from the liquid flowing through the pipe coupling, the gas concentrator being directly received in the unobstructed fluid flow path of the couplings beneath the float.
