SWIVEL WITH OR FOR HYDRANT MANIFOLD FOR INDUSTRIAL FIRE FIGHTING
A swivel with, or for, a hydrant manifold for industrial fire fighting comprising a swivel providing an at least 6 inch flow conduit and preferably including mating male and female sleeves of stainless steel and preferably having at least two rings of stainless steel ball bearings and a location for an interior water seal.
1 . An at least 6 inch swiveled hydrant manifold for industrial fire fighting, comprising;
a hydrant manifold; and
a swivel connected directly or indirectly to the hydrant manifold, structured to connect directly or indirectly to an industrial water supply pipe system;
the swivel providing an at least 6-inch flow conduit and including mating male and female stainless steel sleeves structured for at least 180° relative rotation and having at least two sets of bearings between the male and female sleeves; and
a location for an interior water pressure seal between the male and female sleeves structured to protect bearing contact area from water ingress.
2 . The swiveled hydrant manifold of claim 1 wherein the hydrant manifold is horizontal.
3 . The swiveled hydrant manifold of claim 1 wherein the hydrant manifold is vertical.
4 . The swiveled hydrant manifold of claim 1 wherein the male and female sleeves include stainless steel and the swivel includes a location for an exterior debris seal between the male and the female sleeves.
5 . The swiveled hydrant manifold of claim 1 including sleeves structured for at least 360° relative rotation and including a grease fitting for lubricating area between the sleeves and around the bearings.
6 . The swiveled hydrant manifold of claim 1 wherein the two sets of bearings include two rings of ball bearings and the sleeves and ball bearings including 316 stainless steel.
7 . The swiveled hydrant manifold of claim 1 including a locking mechanism between the two sleeves of the swivel.
8 . The swiveled hydrant manifold of claim 1 including a pair of interlockable flange portions.
9 . A swivel device for an at least 6 inch hydrant manifold for industrial fire fighting, comprising:
a first fitting structured to fixedly attach, directly or indirectly, to a hydrant manifold inlet valve or riser pipe;
a swivel body structured for sealing, rotational attachment, directly or indirectly, to the first fitting and providing a second fitting structured to fixedly attach, directly or indirectly, to a hydrant manifold;
a locking device structured to fix a rotatable attachment position between the swivel body and the first fitting; and
wherein the first fitting and the swivel body provide an at least 6 inch fluid conduit between the first fitting and the second fitting.
10 . The device of claim 9 including the first fitting having a flange for fixedly attaching to a hydrant manifold inlet valve or riser pipe.
11 . The device of claim 9 wherein the second fitting includes a flange for fixedly attaching to a hydrant manifold.
12 . The device of claim 9 wherein the locking device includes a locking portion on the swivel body and a locking flange on the first fitting, the locking portion and flange providing holes for the insertion of a pin.
13 . The device of claim 9 including mating rotatable male and female sleeves.
14 . The device of claim 13 wherein the male and female sleeves include stainless steel.
15 . The device of claim 13 that includes at least two rings of stainless steel ball bearings located between the male and female sleeves.
16 . The device of claim 15 that includes a grease fitting for communicating lubricant between the sleeves and around the ball bearings.
