The present invention relates to valve arrangements for use with water meters.
Water meters, especially for determining residential water use or for determining commercial water use, generally have an inlet and an outlet arranged horizontally on left and right sides of the water meter. Plumbing connections are needed to connect the inlet of the water meter to the water main or other source of potable water. Plumbing connections are also needed to connect the outlet of the water meter to the main supply piping for the residence or other structure to be served by the water meter. Typically, these plumbing connections are made on site using various suitable, conventional fittings such as pipe nipples and valves. Although various attempts have been made in the prior art to provide an assembly for facilitating the connection of a water meter to inlet and outlet piping, the need remains for a valve arrangement that facilitates the prompt and efficient connection of a water meter, especially in commercial, domestic or residential settings.
In the prior art, for example, it is known from U.S. Pat. No. 6,588,800 of Meli to provide a connector body in which a pipe loop is provided to receive a water meter between coaxial ends of the pipe loop. A connector body is provided to supply one end of the pipe loop with water and to direct another end of the pipe loop to the structure to be served by the water meter. In the Meli patent, the connector body is configured so that the connector body may be provided within a straight length of pipe with the ends of the pipe loop arranged at right angles to one another.
Various prior art valve arrangements are also known for connecting gas meters to piping. For example, U.S. Pat. No. 6,382,679 of Hall discloses a meter loop frame assembly in which inlet and outlet piping connections are joined together by a brace. The inlet and outlet piping is configured for connection to the top of a gas meter. Similarly, U.S. Pat. No. 2,632,328 of McChesney discloses a gas meter connection assembly in which inlet and outlet piping is connected by a bar. The inlet and outlet piping is arranged to connect to the sides of the gas meter. Other meter piping arrangements are disclosed in U.S. Pat. No. 6,363,782 of Hendey and in U.S. Patent Publication No. 2008/0295907 of Noll et al. U.S. Pat. No. 1,128,097 of Bockelman discloses a shower bath body and U.S. Pat. No. 4,726,399 of Miller discloses a modular manifold having a plurality of fittings.
Water meter installation arrangements are also commercially available from The Ford Meter Box Company, Inc. of Indiana and especially from their website (http://www.fordmeterbox.com/pages/downloads/catalog.htm) at Section B, Section E and Section F. Other water meter installation arrangements are known from the Mueller Company Full Water online catalog in sections 8.1, 8.2, and 8A.1-8A.47 available on the Mueller Company website (www.muellercompany.com/water/products). Other water meter installation arrangements are known from the AY McDonald company website (http://www.aymcdonald.com/water.cfm) in sections identified for Insetters, Iron Meter Yokes, Resetters, and Meter Setters.
Accordingly, the need remains for a valve arrangement for use with a water meter or other metering device to connect the meter to inlet and outlet piping and especially using different joint or coupling configurations in an economical and efficient manner which overcomes the difficulties in the prior art.
In various preferred embodiments of the present invention, a valve arrangement for use with a water meter comprises a first valve comprising a first valve housing, a first inlet, and a first outlet, with the first inlet and the first outlet of the first valve being oriented substantially perpendicular to one another. A second valve comprises a second valve housing, a second inlet, and a second outlet, with the second inlet and the second outlet of the second valve being oriented substantially perpendicular to one another. The first inlet of the first valve and the second outlet of the second valve are substantially coaxial with one another, and the first outlet of the first valve and the second inlet of the second valve are oriented substantially 180° apart from one another. The first valve housing and the second valve housing are joined together by a connection member.
In a preferred embodiment, the connection member is integrally provided with the first valve housing and the second valve housing, and the connection member does not provide fluid communication between the first valve and the second valve.
In another preferred embodiment, the connection member is solid and each of the first inlet and the second outlet comprises male threads.
In another preferred embodiment, each of the first inlet and the second outlet may comprise a swivel nut having female threads.
In another preferred embodiment, the valve arrangement further comprises a pipeline attachment member for the first inlet. The pipeline attachment member may comprise a compression joint for copper pipe, or a compression joint for steel pipe, or a press fitting for copper pipe, or a press fitting for steel pipe, or a capillary end joint for copper pipe, or a male thread joint fitting, or a female thread joint fitting.
In another preferred embodiment, the valve arrangement further comprises a first substantially U-shaped conduit having a first end in fluid communication with the first outlet and a second end adapted for connection to an inlet of a water meter; and, a second substantially U-shaped conduit having a first end in fluid communication with the second inlet and a second end adapted for connection to an outlet of the water meter. The second end of the first substantially U-shaped conduit and the second end of the second substantially U-shaped conduit are preferably generally opposite one another to receive the water meter therebetween.

The present invention will appear more clearly from the following detailed description of several embodiments illustrated in the enclosed figures in which:
With reference to
The second valve 12 has a second inlet 26 which is connected to a second generally U-shaped conduit 28. The second valve 12 also has a second outlet 30 which in this preferred embodiment has male threads. The second generally U-shaped conduit 28 is preferably connected to the second inlet 26 by a press fitting connection 32. If desired, the second generally U-shaped conduit 28 may be connected to the second inlet 26 by brazing (not shown) or by a soldered connection (not shown) or by any other suitable connection for plumbing fittings as readily apparent to one of ordinary skill in the art. A valve actuator 34 for the second valve 12 has a handle 36 which may be rotated preferably through 90° to open and close the second valve 12. For example, when the valve actuator 34 is in a first position, fluid communication is permitted between the second inlet 26 and the second outlet 30 and when the valve actuator is moved to a second position (e.g., rotated through 90°) fluid communication between the first inlet 26 and the first outlet 30 is prohibited.
The first generally J-shaped conduit 18 has a second end 38 provided with a swivel nut 40 for connection to an inlet of a water meter (not shown). Similarly, the second generally U-shaped conduit 28 has a second end 42 provided with a swivel nut 44 for connection to an outlet of a water meter (not shown). The first generally U-shaped conduit 18 is oriented slightly upwardly and the second generally U-shaped conduit 28 is oriented slightly downwardly so that the ends of the conduits 18, 28 are generally coaxial with one another and spaced apart a distance corresponding to the distance between the inlet and outlet of the water meter to be installed therebetween. The ends 38, 42 of the generally U-shaped conduits 18, 28 may be provided with appropriate flanges or other connection configurations depending upon the configuration of the water meter (not shown) to be connected to the generally U-shaped conduits.
A connection member 46 is provided between the first valve 10 and the second valve 12 to rigidly connect the two valves together. In the preferred embodiment, the connection member is solid and has flat surfaces to facilitate the use of a wrench to prevent rotation of the connection member while the first inlet 14 and the second outlet 30 are being connected to other plumbing fittings. In addition, the connection member 46 has a sufficient height to permit unobstructed movement of the valve handles 24, 36 between the open configuration and the closed configuration of the respective valves 10, 12.
In the preferred embodiment, the connection member 46 is formed together with the housing for the first valve 10 and the housing for the second valve 12. For example, the first valve housing, the second valve housing and the connection member 46 may be formed as a unitary member in a single forging.
In the preferred embodiment, the connection member 46 connects the first valve 10 to the second valve 12 but does not permit fluid communication between the valves through the connection member. Instead, fluid communication is permitted through the first valve inlet 14 to the first valve outlet 16 and then through the first generally U-shaped conduit 18 and through the water valve (not shown) and then through the second generally U-shaped conduit 28 to the second inlet 26 and then through the second outlet 30.
In the preferred embodiment, the connection member 46 connects the first valve 10 to the second valve 12 with the first inlet 14 generally coaxial with the second outlet 30 and with the first outlet 16 oriented generally 180° apart from the second inlet 26. In this way, the ends of the first and second generally U-shaped conduits 18, 28 may be oriented opposite one another and coaxial to one another so as to receive the water meter therebetween.
