Abstract
Abstract A header pipe has an external sealing surface. A diaphram type control valve is externally mounted to the header pipe. An outlet pipe is mounted to the header pipe, enters and crosses the flow passage in the header pipe, and has a threaded end. The body of the control valve has a skirt which bears against the sealing surface, and a tube which is threaded onto the threaded end of the outlet pipe to mount the valve and to bring the skirt against the sealing surface. A peripheral seal fits between the skirt and the sealing surface. It may be a cup-sectioned seal which is pressure-biased to form the seal.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
180 words
In combination: a header pipe having an internal flow passage, a wall with a sealing surface, and an aperture through said sealing surface into said flow passage; an outlet pipe mounted to and passing through said wall, crossing said flow passage and having a threaded end; a diaphragm-type valve having a body which includes a peripheral skirt adapted to bear against said sealing surface, a web, a threaded tubular member supported by said web threadedly engaged to the said end of said outlet pipe and operative to bring said skirt toward and against said sealing surface, thereby to mount said diaphragm-type valve to said header pipe, said web providing a fluid passage extending between said flow passage and said outlet pipe, said diaphragm-type valves being disposed outside of said header pipe, a valve seat and a valving diaphragm in said body in fluid controlling position between said end of said outlet pipe and said fluid passage, and port means for admitting control pressure to said diaphragm; and peripheral seal means disposed and sealing between said skirt and said sealing surface.
Claim 2
Dependent Claim
180 words
In combination: a header pipe having an internal flow passage, a wall with a sealing surface, and an aperture through said sealing surface into said flow passage; an outlet pipe mounted to and passing through said wall, crossing said flow passage and having a threaded end; a diaphragm-type valve having a body which includes a peripheral skirt adapted to bear against said sealing surface, a web, a threaded tubular member supported by said web threadedly engaged to the said end of said outlet pipe and operative to bring said skirt toward and against said sealing surface, thereby to mount said diaphragm-type valve to said header pipe, said web providing a fluid passage extending between said flow passage and said outlet pipe, said diaphragm-type valves being disposed outside of said header pipe, a valve seat and a valving diaphragm in said body in fluid controlling position between said end of said outlet pipe and said fluid passage, and port means for admitting control pressure to said diaphragm; and peripheral seal means disposed and sealing between said skirt and said sealing surface.
Claim 3
Dependent Claim
14 words
A combination according to claim 1 in which said seal means in an O-ring.
Claim 4
Dependent Claim
41 words
A combination according to claim 1 in which said seal means is a cup-sectioned seal, and in which means is provided to apply pressurized fluid to said seal to press it into sealing relationship between said sealing surface and said skirt.
Claim 5
Dependent Claim
14 words
A combination according to claim 1 in which said header pipe is substantially square.
Claim 6
Dependent Claim
14 words
A combination according to claim 4 in which said seal means is an O-ring.
Claim 7
Dependent Claim
41 words
A combination according to claim 4 in which said seal means is a cup-sectioned seal, and in which means is provided to apply pressurized fluid to said seal to press it into sealing relationship between said sealing surface and said skirt.
Claim 8
Dependent Claim
18 words
A combination according to claim 1 in which said valve seat is circular, and said diaphragm overlays it.
Claim 9
Dependent Claim
41 words
A combination according to claim 7 in which said seal means is a cup-sectioned seal, and in which means is provided to apply pressurized fluid to said seal to press it into sealing relationship between said sealing surface and said skirt.
Claim 10
Dependent Claim
14 words
A combination according to claim 8 in which said header pipe is substantially square.
