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.
Claims13
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, the outer sleeve having a first axis;
- an inner sleeve connected to the other of the first and second shutoff valves, wherein the inner sleeve is coupled to the outer sleeve for rotation with respect to the first axis and for sliding along the first axis such that a rotational orientation and a lay-length of the backflow prevention assembly can be varied and set to a desired rotational orientation and lay-length;
- 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.
