Abstract
Abstract Individual pipes which constitute a pipe line are in the form of a tube divided into a main space and a secondary space. Plug members are located at the ends of the secondary space to sealingly define the secondary space and the outer peripheral wall of the tube defining the secondary space portion is provided with one or more holes from which a fluid maintained under pressure in the secondary space is sprayed outwardly. The main space and the secondary space are connected by a passage having means for adjusting the flow rate of fluid from the main space to the secondary space.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
186 words
A pipe line comprising: a plurality of spray pipe units, each of said pipe units having their opposite ends open and including a partition provided within the inner space thereof so as to divide said inner space into a main space and a secondary space, at least one spray hole provided within the outer peripheral wall of the pipe defining said secondary space, a plug member positioned within each of the opposite ends of the secondary space so as to seal the same, means for fluidically communicating the main space with the secondary space, and means for adjustably restricting said communicating means between fully restricted and non-restricted states so as to adjust the flow rate of fluid from the main space into the secondary space from substantially zero flow to full flow conditions; said pipe units being serially disposed in an end-to-end manner such that the main spaces of said pipe units are fluidically communicated with each other; and sleeve-shaped coupling means disposed about the joints of said pipe units defined by the adjacent ends thereof for connecting said pipe units together in a sealed manner.
Claim 2
Dependent Claim
186 words
A pipe line comprising: a plurality of spray pipe units, each of said pipe units having their opposite ends open and including a partition provided within the inner space thereof so as to divide said inner space into a main space and a secondary space, at least one spray hole provided within the outer peripheral wall of the pipe defining said secondary space, a plug member positioned within each of the opposite ends of the secondary space so as to seal the same, means for fluidically communicating the main space with the secondary space, and means for adjustably restricting said communicating means between fully restricted and non-restricted states so as to adjust the flow rate of fluid from the main space into the secondary space from substantially zero flow to full flow conditions; said pipe units being serially disposed in an end-to-end manner such that the main spaces of said pipe units are fluidically communicated with each other; and sleeve-shaped coupling means disposed about the joints of said pipe units defined by the adjacent ends thereof for connecting said pipe units together in a sealed manner.
Claim 3
Dependent Claim
87 words
A pipe line according to claim 1 in which: the means for communicating the main space with the secondary space comprises a passage provided in the partition in alignment with a guide hole provided in the outer peripheral wall, an adjusting member is threaded into the guide hole of the outer peripheral wall, and the leading end of the adjusting member is movable relative to the passage of the partition so as to adjust the flow rate of fluid from the main space into the secondary space.
Claim 4
Dependent Claim
17 words
A pipe line according to claim 1 in which spray nozzles are mounted in the spray holes.
Claim 5
Dependent Claim
19 words
A pipe line according to claim 1 in which an indication line is drawn on the outer peripheral wall.
Claim 6
Dependent Claim
28 words
A pipe line according to claim 2 in which the adjusting member is threaded into a cylindrical insert provided with a flange portion inserted into the guide hole.
Claim 7
Dependent Claim
58 words
A pipe line according to claim 2, wherein: the leading end of said adjusting member is non-threaded and tapered so as to be capable of passing through said passage defined within said partition without damaging the wall portion of said partition defining said passage and yet capable of providing a fluid flow rate within said zero flow-full range.
