Sliding vessel mount
An assembly is configured for use in a module that is configured to hold a plurality of vessels, at least one of the plurality of vessels including a neck. The assembly includes a bracket and a mounting ring. The bracket has an opening and includes a plate and a collar. The plate has a fixed position along the longitudinal axis, and the collar extends from the plate. The mounting ring includes a second aperture configured to surround the neck, and the mounting ring comprises an outer surface configured to move within the opening along the longitudinal axis. In another aspect, a module is configured for attachment to a plurality of pressure vessels and includes a frame and a bracket. A method is described for supporting a pressure vessel.
1 . An assembly configured for use in a module that is configured to hold a plurality of vessels, at least one of the plurality of vessels comprising a neck and having a longitudinal axis, the assembly comprising:
a bracket having an opening and comprising:
a plate having a fixed position along the longitudinal axis; and
a collar extending from the plate; and
a mounting ring comprising a second opening configured to surround the neck, the mounting ring comprising an outer surface configured to slide linearly within the opening along the longitudinal axis.
2 . The assembly of claim 1 , wherein the mounting ring comprises a first recess configured to surround an armature attached to the neck.
3 . The assembly of claim 2 , wherein the mounting ring comprises a second recess configured to surround a domed end of the at least one of the plurality of vessels.
4 . The assembly of claim 1 , wherein the mounting ring comprises a first section and a second section connected at a joint.
5 . The assembly of claim 1 , comprising a slide ring received in a first recess of the bracket at the opening.
6 . The assembly of claim 5 , comprising a scraper ring received in a second recess of the bracket at the opening.
7 . The assembly of claim 6 , wherein the slide ring is positioned closer to, and the scraper ring is positioned farther from, a domed end of the at least one of the plurality of vessels.
8 . The assembly of claim 1 , wherein the mounting ring comprises a ridge at the second opening configured for insertion into a groove of the neck.
9 . A module configured for attachment to a plurality of pressure vessels, at least one of the plurality of pressure vessels comprising a neck and having a longitudinal axis, the module comprising:
a frame comprising a plurality of first apertures, wherein at least one of the plurality of first apertures is configured for passage of the neck therethrough;
a bracket having an opening and comprising:
a plate attached to the frame; and
a collar extending from the plate; and
a mounting ring comprising a second aperture configured to surround the neck, the mounting ring comprising a cylindrical surface configured to slide linearly within the opening along the longitudinal axis.
10 . The module of claim 9 , wherein the mounting ring comprises a first recess configured to surround an armature attached to the neck.
11 . The module of claim 10 , wherein the mounting ring comprises a second recess configured to surround a domed end of the at least one of the plurality of pressure vessels.
12 . The module of claim 9 , wherein the mounting ring comprises a lower shell and an upper shell connected at a joint.
13 . The module of claim 9 , comprising a slide ring received in a first recess of the bracket at the opening.
14 . The module of claim 13 , comprising a scraper ring received in a second recess of the bracket at the opening.
15 . The module of claim 14 , wherein the slide ring is positioned closer to, and the scraper ring is positioned farther from, a domed end of the at least one of the plurality of pressure vessels.
16 . The module of claim 9 , wherein a ridge at the second aperture is disposed in a groove of the neck.
17 . A method for supporting a pressure vessel comprising a neck and having a longitudinal axis, the method comprising:
passing the neck through a first aperture of a frame;
joining first and second portions of a mounting ring around the neck, wherein the mounting ring is axially fixed on the neck;
linearly sliding an opening of a bracket on an outer surface of the mounting ring along the longitudinal axis; and
attaching the bracket to the frame.
18 . The method of claim 17 , comprising changing a length of the pressure vessel so that the mounting ring moves axially within the opening.
19 . The method of claim 18 , wherein the bracket comprises an annular bearing disposed at the opening, the method including moving the outer surface of the mounting ring against the annular bearing.
20 . The method of claim 18 , wherein the bracket comprises a resilient annulus disposed at the opening, the method including moving the outer surface of the mounting ring against the resilient annulus.
