Abstract
Abstract A multiport sampling valve for corrosive gases and liquids. The multiport sampling valve has a hollow barrel, a series of pairs of arms projecting radially therefrom, and a plug inserted into and adapted for rotation in the barrel, the plug having a series of pairs of holes which are each alignable with each of said pairs of arms to allow the passage of a gas from one arm of a pair through the plug and out the other arm of a second pair extending from the barrel to an analyzer.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
99 words
A multiport sampling valve for corrosive gases and liquids which pass through said valve at a pressure ranging between 10 6 mm Hg. and 5 atmospheres, said sampling valve comprising a hollow barrel, a series of pairs of arms spaced circumferentially around and projecting radially from said barrel, a plug inserted into and adapted for rotation in said barrel, said plug having a series of pairs of holes spaced circumferentially around said plug with each pair joined by a passage extending longitudinally in said plug, each of said pairs of holes being alignable with each pair of said arms.
Claim 2
Dependent Claim
99 words
A multiport sampling valve for corrosive gases and liquids which pass through said valve at a pressure ranging between 10 6 mm Hg. and 5 atmospheres, said sampling valve comprising a hollow barrel, a series of pairs of arms spaced circumferentially around and projecting radially from said barrel, a plug inserted into and adapted for rotation in said barrel, said plug having a series of pairs of holes spaced circumferentially around said plug with each pair joined by a passage extending longitudinally in said plug, each of said pairs of holes being alignable with each pair of said arms.
Claim 3
Dependent Claim
41 words
A sampling valve according to claim 1, wherein said pairs of arms projecting radially from said barrel are circumferentially spaced at 90* apart around said barrel, and said holes in said plug are circumferentially spaced at 90* apart around said plug.
Claim 4
Dependent Claim
50 words
A sampling valve according to claim 1, wherein said pairs of holes in said plug are alignable with said pairs of arms projected radially from the barrel to allow the simultaneous multisampling of a single stream of a gas or liquid, or the simultaneous multisampling of different gases or liquids.
Claim 5
Dependent Claim
18 words
A sampling valve according to claim 1, wherein said barrel, arms, and plug are made of Pyrex glass.
Claim 6
Dependent Claim
28 words
A multiport sampling valve according to claim 1, wherein the valve is adopted to sample gases and liquids at temperatures ranging from about -100* to about 500* C.
Claim 7
Dependent Claim
23 words
A multiport sampling valve according to claim 1, wherein the valve is adapted to take samples of gases and liquids of different volumes.
Claim 8
Dependent Claim
49 words
A multiport sampling valve according to claim 1 wherein said plug is fitted with a shoulder ridge and is secured in said barrel by a mounting means, said mounting means being adapted to provide a pressure against said shoulder ridge in order to secure said plug in said barrel.
Claim 9
Dependent Claim
64 words
A sampling valve according to claim 7 wherein said mounting means is comprised of a base plate, a stabilizing plate and a top pressure plate joined together by four rods said stabilizing plate being positioned between said base plate and said top pressure plate being positioned so as to provide pressure against said shoulder ridge in order to secure said plug in said barrel.
Claim 10
Dependent Claim
106 words
A multiport sampling valve for corrosive gases and liquids which pass through said valve at a pressure ranging between 10 6 mm Hg. and 5 atmospheres, and at a temperature ranging from about -100* to about 500* C., said sampling valve comprising a hollow barrel, a series of pairs of arms spaced circumferentially around and projecting radially from said barrel, a plug inserted into and adapted for rotation in said barrel, said plug having a series of pairs of holes with each pair joined by a passage Extending longitudinally in said plug, each of said pairs of holes being alignable with each pair of said arms.
Claim 11
Dependent Claim
106 words
A multiport sampling valve for corrosive gases and liquids which pass through said valve at a pressure ranging between 10 6 mm Hg. and 5 atmospheres, and at a temperature ranging from about -100* to about 500* C., said sampling valve comprising a hollow barrel, a series of pairs of arms spaced circumferentially around and projecting radially from said barrel, a plug inserted into and adapted for rotation in said barrel, said plug having a series of pairs of holes with each pair joined by a passage Extending longitudinally in said plug, each of said pairs of holes being alignable with each pair of said arms.
Claim 12
Dependent Claim
41 words
A sampling valve according to claim 9 wherein said pairs of arms projecting radially from said barrel are circumferentially spaced at 90* apart around said barrel, and said holes in said plug are circumferentially spaced at 90* apart around said plug.
Claim 13
Dependent Claim
50 words
A sampling valve according to claim 9 wherein said pairs of holes in said plug are alignable with said pairs of arms projected radially from the barrel to allow the simultaneous multisampling of a single stream of a gas or liquid, or the simultaneous multisampling of different gases or liquids.
Claim 14
Dependent Claim
23 words
A multiport sampling valve according to claim 7, wherein the valve is adapted to take samples of gases and liquids of different volumes.
