Abstract
A double-walled flexible dispenser sump connection system prevents fuel leaks into a dispenser sump located below a fuel dispenser. An inner flexible connector and an outer flexible connector are configured such that the dispenser sump connection system may be installed on newly constructed fuel delivery systems or be retrofitted onto existing fuel delivery systems in order to bring them into compliance with recently environmental regulations.
Description
- This application is a continuation application of application Ser. No. 11/061,388 filed Feb. 18, 2005, currently pending, the entire contents of which are incorporated herein by reference.
- This invention relates generally to fuel dispenser sumps used in gas stations and in similar applications, and more particularly to a double-walled flexible dispenser sump connection system that provides a safeguard against leaks from dispenser sumps located beneath the gasoline dispensers.
- State environmental and energy agencies require strict compliance with laws and regulations regarding fuel storage and conveyance, in particular regarding containment of fuel within the pipes and other components beneath the ground surface at gas stations. Piping systems for conveying the fuel between the underground tanks and dispensers must be pressurized and vacuum sealed to detect and contain leaks therein.
- Referring to
FIG. 1 , there is shown a common dispensersump connection system 10 below adispenser 12 at a gas station. Fuel is conveyed from atank 14 through a primaryinner pipe 16, traditionally two inches in diameter, into adispenser sump 18 below thefuel dispenser 12. Once inside the dispenser sump 18 theinner pipe 16 continues through anelbow joint 20 to a connectinginner pipe 22, which couples to ashear valve 24 located at the bottom of thedispenser 12. Theshear valve 24 prevents fuel spills or leaks in the event that thedispenser 12 is displaced from thedispenser sump 18. - A secondary
outer pipe 26, traditionally three inches in diameter, encloses theinner pipe 16 from thetank 14 to thedispenser sump 18. Theouter pipe 26 prevents fuel from entering into and contaminating the groundsoil and/or the atmosphere. The interstitial space between theouter pipe 26 and theinner pipe 16 is either pressurized or vacuum sealed to provide additional protection against leaks. - Although the
outer pipe 26 contains any leaks between thetank 12 and thedispenser sump 18, theouter pipe 26 terminates into a boot at thedispenser sump 18, leaving theinner pipe 16 is exposed inside thedispenser sump 18. Therefore, there are no safeguards to detect or contain leaks that occur inside thedispenser sump 18, which can result in leaks into the groundsoil surrounding the dispenser sump and/or into the atmosphere. Recently, regulations have been passed in several states such as California which require safeguards be installed to prevent leaks from dispenser sumps. Currently the approved safeguards require retrofitting the existingdispenser sump 18 with the equivalent of an outer sump around the dispenser sump within the space between the outer and inner sump being either pressurized or vacuum sealed, or replacing the existing dispenser sump with a double-walled pressurized sump. The cost to install the outer sump or replace the existing sump costs approximately $2,000 minimum per dispenser. Considering that most gas stations have multiple dispensers, the cost to retrofit the existing sumps to bring them into compliance can be substantial. - The present invention comprises a dispenser sump connection system which overcomes the foregoing and other difficulties which have long since characterized the prior art. In accordance with the broader aspects of the invention, an outer and inner flexible connector system provides protection against fuel leakage from the dispenser sump. The inner flexible connector connects the primary inner pipe to the shear valve. The outer flexible connector completely encloses the inner flexible connector from the sump wall to the shear valve. The interstitial space between the outer flexible connector and the inner flexible connector is pressurized and/or be vacuum sealed thereby preventing any fuel leakage into the dispenser sump.
- The outer and inner flexible connector system can be retrofitted inside existing dispenser sumps at a minimal cost per dispenser. The present invention provides the high level of protection against leakage required by state environmental agencies and eliminates the need for installing an outer sump or retrofitting with a double-walled sump.
- A more complete understanding of the invention may be had by reference to the following Detailed Description when taken in conjunction with the accompanying Drawings, wherein:
-
FIG. 1 is a sectional view illustrating a prior art fuel delivery and dispenser sump connection system; -
FIG. 2 is a sectional view of the double-walled flexible dispenser sump connection system of the present invention; -
FIG. 3 is an exploded perspective view of the dispenser sump connection system shown inFIG. 2 ; and -
FIG. 4 is a sectional view of the dispenser sump connection system shown inFIG. 2 . - Referring now to the Drawings, and particularly to
FIGS. 2, 3 , and 4 thereof, there is shown the dispensersump connection system 30 of the present invention. An innerflexible connector 32 is connected to theinner pipe 16 for completing the conveyance of fuel to thedispenser 12. An outerflexible connector 34 is installed over and completely encloses the innerflexible connector 32. The lower end of the outerflexible connector 34 is connected in fluid communication with theouter pipe 26. The upper end of the outerflexible connector 34 is connected to theshear valve 24 thereby completing the containment of any leaks from either theinner pipe 16 and the innerflexible connector 32. The interstitial space between the outerflexible connector 34 and the innerflexible connector 32 is either pressurized or vacuum sealed thereby preventing any fuel leakage into thedispenser sump 18. Theflexible connectors - In the embodiment shown in
FIGS. 2 through 4 , the innerflexible connector 32 couples to theinner pipe 16 through anelbow joint 36 comprising aninner elbow joint 38 secured to the distal end of theinner pipe 16 and anouter containment clamshell 40, which glues over theinner elbow joint 38 to contain any leaks that may occur therefrom. The dispensersump connection system 30 of the present invention may be also be secured directly to the inner andouter pipes -
FIG. 3 is an exploded view andFIG. 4 is a sectional view of the dispensersump connection system 30. The innerflexible connector 32 threadedly secures into theinner elbow joint 38, thereby completing the connection of the innerflexible connector 32 to theinner pipe 16. The top of the innerflexible connector 32 has male threads for threadedly securing the innerflexible connector 32 into theshear valve 24. The outerflexible connector 34 installs over the innerflexible connector 32 and is connected to theelbow joint 36 by alower connection ring 42, which extends around the end of theinner elbow joint 38. Theouter containment clamshell 40 when glued over theinner elbow joint 38 covers and thereby contains the connection of thelower connection ring 42 to theinner elbow joint 38. - The lower end of the outer
flexible connector 34 is secured to thelower connection ring 42 by a first hingedcircular clamp 44 having a threadedlocking mechanism 46. Agasket 48 is mounted between the outerflexible connector 34 andlower connection ring 42. Wedge shaped surfaces on the outerflexible connector 34 and on thelower connection ring 42 and corresponding shapes on the inner surfaces of thecircular clamp 44, combined with thegasket 48, cause the outerflexible connector 34 and thelower connection ring 42 to form a compression seal as the threadedlocking mechanism 46 is tightened. - The upper end of the outer
flexible connector 34 is connected to theshear valve 24 by anupper connection ring 50. The outerflexible connector 34 is secured to theupper connection ring 50 by a second hingedcircular clamp 44 having a threadedlocking mechanism 46.
