Swivel with or for hydrant manifold for industrial fire fighting

Abstract

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.

What is claimed is: 
     
         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.
