Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
212 words
A valve for pressure piping comprising a dismantling sleeve constituting part of the piping, said sleeve having opposite ends and including a valve service seat at one end of said dismantling sleeve, an obturator for opening and closing the valve and which seats on said valve service seat when the valve is closed, a case for the valve, said dismantling sleeve being approximately round in cross section, adjustable centering means on said case for making the end of said dismantling sleeve carrying said valve seat round, and means for mounting said dismantling sleeve for axial adjustment with respect to the pressure piping and to said case and comprising a plurality of external ears spaced around the circumference, and on the outer surface, of said dismantling sleeve, a plurality of parallel threaded bolts freely passing through said ears, a series of threaded holes in said valve body into which one of the ends of said bolts are screwed, a flange on the pressure piping for releasably holding the other ends of said bolts, and nuts screwed onto said bolts and located on either side of each of said ears for permitting axial adjustment of said dismantling sleeve and the service seat carried thereby, by changing the positions of said nuts on said bolts.
Claim 2
Dependent Claim
212 words
A valve for pressure piping comprising a dismantling sleeve constituting part of the piping, said sleeve having opposite ends and including a valve service seat at one end of said dismantling sleeve, an obturator for opening and closing the valve and which seats on said valve service seat when the valve is closed, a case for the valve, said dismantling sleeve being approximately round in cross section, adjustable centering means on said case for making the end of said dismantling sleeve carrying said valve seat round, and means for mounting said dismantling sleeve for axial adjustment with respect to the pressure piping and to said case and comprising a plurality of external ears spaced around the circumference, and on the outer surface, of said dismantling sleeve, a plurality of parallel threaded bolts freely passing through said ears, a series of threaded holes in said valve body into which one of the ends of said bolts are screwed, a flange on the pressure piping for releasably holding the other ends of said bolts, and nuts screwed onto said bolts and located on either side of each of said ears for permitting axial adjustment of said dismantling sleeve and the service seat carried thereby, by changing the positions of said nuts on said bolts.
Claim 3
Dependent Claim
67 words
A valve as claimed in claim 1, wherein said adjustable centering means comprises a centering ring surrounding said dismantling sleeve near the end thereof with said service seat, and a plurality of circumferentially spaced, radially extending screws in said valve case and surrounding said centering ring for moving the latter radially to press against said dismantling sleeve to make the sleeve round and to center the sleeve.
Claim 4
Dependent Claim
78 words
A valve as claimed in claim 2, wherein said dismantling sleeve is located within said valve case and the pressure piping, said valve case having a recess receiving said centering ring, a plurality of threaded holes in said valve case circumferentiaLly surrounding said recess for receiving said plurality of screws, and sealing means for ensuring a fluidtight connection between said valve case and the pressure piping, on the one hand, and said dismantling sleeve on the other hand.
Claim 5
Dependent Claim
30 words
A valve as claimed in claim 3, wherein the pressure piping includes two spaced sections between which the valve is located, and said dismantling sleeve connects the two sections together.
