Abstract
The Re-Corable Coaxial Hose System allows temperature control to be added around material-carrying tubing in both new and existing dispensing systems. The jacketing system seals around the material-carrying tube and allows a thermal transfer fluid to be circulated in the resulting annular space so as to change the temperature of the material being dispensed. Because the system is comprised of a series of tubing and hoses it is flexible and can be routed around corners and through wire tracks and can be used in both manual and robotic applications. Because the seals around the material-carrying tube can be released and subsequently re-sealed, the internal material-carrying tube can be replaced, defined as “re-coring” the hose assembly.
Claims9
A thermal fluid transfer hose system comprising:
- at least one outer hose jacket member having a first end and an opposed second end and an interior channel located therebetween;
- and
- at least one block assembly, the block assembly defining a central shaft extending therethough, the block assembly in fluid-tight connection to either the first or second end of the outer hose jacket member such that the central shaft extending through the block assembly and the interior channel defined in the outer jacket hose are in coaxial engagement with one another, wherein the outer hose jacket and the at least one block assembly are configured to receive a process fluid and define a process fluid conveying conduit therethrough and to define and annular region between an outer wall of the process fluid conduit and the inner wall of the outer hose jacket member, wherein the at least one block assembly comprises:
- a central body having a first end and an opposed second end with the central shaft extending therethrough, the first end of the central body of the at least one block assembly having a hose jacket member engaging region and the second end of the central body of the at least one block assembly having a fluid seal engaging region;
- a fluid seal composed of a compressible elastomeric material, the fluid seal having seal body, the seal body having a first end and an second end opposed to the first end, the first end of the seal body having a first fluid seal surface configured to contact the seal engaging region defined in the central body of the block assembly and wherein the second end of the fluid seal body has a second fluid seal surface opposed to the first fluid seal surface— and a central shaft extending from the first end of the seal body to the second end of the seal body, wherein the central shaft defined in the seal body of the fluid seal has an inner diameter that can vary between a compressed inner diameter value and an uncompressed inner diameter value wherein the compressed inner diameter value is smaller than the uncompressed diameter value and wherein the fluid seal further includes an outer side surface, the outer side surface coaxially disposed relative to the central shaft, the outer side surface having an outer diameter, the outer diameter of the outer side surface having a compressed outer diameter value and an uncompressed outer diameter value, wherein the compressed outer diameter value is greater than the uncompressed outer diameter value
- a compression cap in releasable contact with the central body, the compression cap in contact with the second end of the fluid seal, the compression cap moveable from a first position wherein the central shaft defined in the fluid seal is at the first inner diameter value and a second position wherein the central shaft defined in the fluid seal is at the second inner diameter, the compression cap having a central aperture concentrically disposed relative to the central shaft, the central aperture having an inner diameter that is greater than the inner diameter of the central shaft such that a portion of the second end of the fluid seal portion is exposed when the thermal fluid transfer hose system is in a use position.
