Abstract
A backflow prevention assembly is configurable with varying lay-lengths and orientations. The assembly includes coupling assemblies and valve bodies that adjust in length and/or rotation to allow for the varying lay-lengths and orientations of the backflow prevention valves and assemblies with and without certification. A coupling assembly is connected to a backflow prevention valve and includes an outer sleeve and an inner sleeve that is slidingly received within the outer sleeve. The lay-length is adjusted by slidably moving the inner and outer sleeves with respect to one another.
Claims29
A backflow prevention assembly, comprising:
- a first shutoff valve;
- a second shutoff valve;
- an outer sleeve connected to one of the first and second shutoff valves;
- an inner sleeve connected to the other of the first and second shutoff valves and slidingly received within the outer sleeve such that a lay-length of the backflow prevention assembly can be varied;
- a first component configured to urge the inner and outer sleeves away from one another along a common axis;
- a fluid seal positioned between the inner sleeve and the outer sleeve;
- and
- a check valve, connected to the inner sleeve, configured to allow fluid flow in a single direction.
A backflow prevention assembly, comprising:
- a first shutoff valve;
- a second shutoff valve;
- a first backflow prevention valve connected between the first and second shutoff valves;
- and
- a coupling assembly connected to at least one of the first backflow prevention valve, the first shutoff valve and the second shutoff valve, wherein the coupling assembly, the first backflow prevention valve and the first and second shutoff valves define a lay-length of the backflow prevention assembly, the coupling assembly including:
- a first end;
- a second end;
- an outer sleeve extending from the first end;
- an inner sleeve extending from the second end and slidingly received within the outer sleeve such that a distance between the first and second ends of the coupling assembly can be varied to adjust the lay-length of the backflow prevention assembly;
- a first component configured to urge the inner and outer sleeves away from one another along a common axis;
- and
- a fluid seal positioned between the inner sleeve and the outer sleeve.
A backflow prevention assembly having a variable lay-length, comprising:
- a first shutoff valve;
- a second shutoff valve;
- a first backflow prevention valve connected between the first shutoff valve and the second shutoff valve;
- and
- a coupling assembly, connected to at least one of the first backflow prevention valve, the first shutoff valve or the second shutoff valve, including:
- a first end;
- a second end;
- an outer sleeve extending from the first end;
- an inner sleeve extending from the second end and slidingly received within the outer sleeve;
- a first component configured to urge the inner and outer sleeves away from one another along a common axis;
- and
- a fluid seal positioned between the inner sleeve and the outer sleeve,
- wherein the lay-length is varied by sliding the inner and outer sleeves with respect to one another along a common axis.
