FIG. 3
PATENTEUFEB 15 I972 LORRELL C. MSFARLAND MULTITUBULAR PRESSURE TANK BACKGROUND OF THE INVENTION A Field of the Invention The present invention relates to pressure tanks and more particularly to a fluid-containing pressure tank formed by a plurality of relatively small tubular members.
Tanks formed of synthetic materials, such as plastic, are needed for storing soft water, sulphur water, acids or other materials which tend to oxidize or corrode metallic con tainers. In order to dispense errosive fluids it is usually necessary that they be contained under greater than atmospheric pressure which usually requires a thickened wall structure to contain the necessary pressure. Furthermore, space limitations for conventional tanks precludes their use in many installations. To fully utilize available space in some installations necessitates forming a tank having a configuration conforming to the available space which heretofore has been impractical from an economic viewpoint. I have found that a pressure tank may be formed by using a plurality of tubular members arranged in parallel juxtaposed relation and connected for intercommunication at their respective ends by a header. The relatively small, size of the tubes used, such as plastic, copper or aluminum, permits the necessary pressure for exhausting the fluid out of the tubes and eliminates the necessity for a thickened wall structure. Furthermore, as one or more of the tubes has the fluid exhausted therefrom these tubes can be individually closed while utilizing the fluid from the remaining tubes. A baffle, slidably sealing with the interior of each tube, divides the tube to form a liquid and an air compartment to place the liquid under a greater than atmospheric pressure.
SUMMARY OF THE INVENTION A plurality of relatively small tubular members are arranged in parallel juxtaposed relation. A header extends transversely across the respective ends of the tubes and is provided with sockets surrounding and sealing with the adjacent end portion of the respective tube. The header further provides communication between the tube ends for admitting air at one end and admitting and removing fluid from the opposite end.
A baffle or divider, slidably sealing with the interior wall surface of the respective tube, forms an air chamber at one end of each tube and a liquid chamber at the opposite end thereof.
The principal object of this invention is to provide a pressure tank of substantially any desired transverse configuration which is formed by a plurality of tubular members arranged in juxtaposed relation and interconnected at their respective ends by a header.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a vertical cross-sectional view, partially in elevation, of a preferred embodiment of the device;
FIGS. 2 and 3 are vertical cross-sectional views of alternative embodiments of the device;
FIG. 4 is a horizontal cross-sectional view taken substantially along the line 44 ofFIG. 3; and,
FIGS. 5, 6 and 7, are transverse cross-sectional views of alternative configurations of the tank forming tubes.
DESCRIPTION OF THE PREFERRED EMBODIMENTS vided with a like plurality of relatively sort tubes fonning sockets 22 open toward and coaxially surrounding the respective adjacent end portions of the tubes 12 and 14. The free end of the circular wall forming the sockets 12 is diametrically enlarged, as at 24, and provided with an annular groove on its inner surface adjacent its free end for receiving a circular seal, such as an Oring 26. The purpose of the sockets and O-ring seal connecting the ends of the tubes 12 and 14 is so that the overall length of the tank 10 may be easily adjusted to conform to the spacing between the base, indicated by the line 28, and an overhead beam or support, indicated at 30. Tube connectors 32 only one being shown, extend through the walls forming the sockets 22 of the top header to provide communication between the upper ends of the tubes 12 and 14.
A valve 34, connected with the upper plate 20, admits air under pressure to the respective tubes. Similarly other tube connectors 36, only one being shown, projecting through the walls 22 of the lower header 16, provide communication between the tubes 12 and 14. Each of the tube connectors 32 and 36 project into the respective socket 22 a distance sufficient to limit longitudinal movement of either of the tubes 12 v and 14 to insure that the seal 26 maintains contact with the periphery of the respective tube.
A cylindericallike member or block 38 is slidably received within the respective tube 12 and 14 and forms a baffle defining an air compartment 40 a one end of the tubes and a fluid containing compartment 42 at the opposite end portion. The baffle is provided with a circumferential recess or groove for nesting a circular seal, such as an O-ring 44, to maintain the air and fluid and in the respective compartments. The purpose of the cylindrical shape of the baffle 38 is to maintain an innerface between the air and water transversely of the respective tube so that the entire device 10 may be positioned horizontally or at any angle between horizontal and vertical and maintain a supply of fluid at the exit header end 16.
In the embodiment of FIG. 1, a fluid supply from a well 46 is connected by piping 48 to one of the sockets 22 with fluid obtained from the well by a motor M driving a pump P to force fluid through a check valve CK. The fluid contained by the tank 10 is drawn off through a valve 50.
Referring now to FIG. 2, a substantially identical tank is indicated at 10A wherein the header plates 20A, projecting beyond the limits of the tubes 12 and 14, are interconnected by bolts and nuts 52 to prevent movement of the respective header l6 and 18 away from the tube ends.
In the embodiment of FIG. 3, the device, indicated generally at 108, comprising a plurality of the tubes 12A and 14A are connected by lower and upper tubular type headers 60 and 62, respectively. Each of these headers comprise a main tube having lateral tubes 64 projecting coaxially toward the respective end of the tubes 12A and 14A.
A cap 66 is threadedly connected with the respective end of each of the tubes 12A and 14A and seals therewith by circular packing 68. Each of the caps 66 is provided with an axial opening defined by an externally threaded projection 70 engaged by a packing nut 72 surrounding the adjacent respective end of the lateral tubes 64 to provide communication between the ends of the tubes 12A and 14A and the respective headers 60 and 62. The upper header tube 62 is provided with the air inlet valve 34 while the lateral tubes of the lower header tube 60 each have a valve 74 interposed therein for interrupting and releasing fluid flow from the respective tube 12A or 14A. These tubes 12A and 14A are similarly provided with the baffles 38. Stabilizers 76, each comprising a sheet of material of selected thickness, are provided with apertures 78 coaxially surrounding the respective tubes 12A and 14A to prevent any lateral movement or axial displacement of these tubes intermediate their ends. While the preferred form of the tubes 12A and 14A is shown circular obviously they may be formed of any other cross-sectional configuration or any combination thereof, as shown by FIGS. 5, 6 and 7, so that the tubes forming the tank may more efficiently utilize the available transverse space in their juxtaposed relation.
Obviously the invention is susceptible to changes or alteradistance slightly less than the length of said relatively tions without defeating its practicability, therefore, I do not short tubes, and tube connectors extending between wish to be confined to the preferred embodiment shown in the and communicating with said relatively short tubes drawings and described herein. between said plates and the adjacent end of said elon- I claim: 5 gated tubular members; and, 1 l.
