    Centering, use and insulated duct that carries it. It allows the union between two concentric tubes (1, 2) of an isolated conduit, with the tubes (1, 2) having separate frames (11, 21). The centering gasket has a "T" section with a longitudinal part (41) and a cross part (42) and a throttle (44) on one side of the joint between both parts (41, 42). Preferably it has saw teeth (43) opposed to the pinch (44) and a curved outer face in the cross part (42). Its use is to maintain the mechanical and thermal separation between the tubes (1, 2) of an isolated conduit formed by two concentric tubes (1, 2) with at least one inner frame (11) in the inner tube (1).

    [0002] Centering gasket, use and insulated conduit that carries it
    [0004] TECHNICAL SECTOR
    [0006] The present invention refers to a centering gasket for ventilation ducts with concentric tubes, which allows to fix its relative position and assists in the connection with the adjacent sections. It also refers to its use and the isolated conduit that carries it.
    [0008] It is applicable in the field of facilities for shops, garages, any type of building, ships, etc.
    [0010] STATE OF THE ART
    [0012] In installations that require it, the circular duct systems that carry heated air, or the extraction of fumes in which condensation must be avoided, incorporate an external insulation that in turn needs to be protected, either for reasons of finish or outdoor mounting requirement. This is why double metal conduits with intermediate insulation are executed.
    [0014] These double conduits are formed by two tubes, generally circular in shape, concentric, and separated by a layer of floating insulating material.
    [0016] These insulated conduits are heavy and gravity itself causes the inner conduit to slide downward, squeezing the layer of insulating material and extending the top of that layer. Therefore, a separating plate is usually placed between the two, to which the frames of the two tubes are welded.
    [0018] This sheet generates, however, a great problem of thermal bridge, when communicating by means of a thermal conductor the two tubes, skipping the insulating material.
    [0020] This type of ducts are made in sections, which are generally joined together by inverted "V" strips that join the outer frames, compressing an elastic element that seals the joint. For this, the outer tubes have a frame Transverse that it is pnza or as ras. You can check a time that is in WO2006035079A1.
    [0022] The applicant is not aware of any system equivalent to the invention.
    [0024] BRIEF EXPLANATION OF THE INVENTION
    [0026] The invention consists of a centering gasket for concentric tube ventilation ducts, according to the claims. It also consists of the use of the centering gasket, and the insulated duct that carries it.
    [0028] This invention allows solving a whole series of problems, such as those listed:
    [0029] 1. Solve the problem of the "thermal bridge" between the inner tube and the outer tube.
    [0030] 2. Be a means of holding and centering the two concentric tubes, keeping the inner tube floating with respect to the outside.
    [0031] 3. Facilitate the sealing with the adjacent duct section, by allowing the support of the joint of a section with the joint of the adjacent section. The method used to join the sections will press one joint against the other.
    [0033] The centering seal of the invention is provided for the connection between two concentric tubes of an isolated conduit, the inner tube having an inner frame (facing outwards). It has a "T" section with a longitudinal part and a crossed part, and a choke on one side of the joint between both parts.
    [0035] In a preferred embodiment, it also has saw teeth on the face of the longitudinal part opposite to the throttle.
    [0037] In another embodiment, the cross part has a curved outer face.
    [0039] The invention also relates to the use of the centering gasket to maintain the separation between the tubes of an insulated duct formed by two concentric tubes, of which the inner tube has an inner frame oriented towards the outside of the inner tube. It is not relevant for this use if the outer tube also has its own frame, but it is the most common and preferred solution.
    [0040] em s, it is n o o eo ea nvenc n to achieve a con uco handle or orm or by two concentric tubes, separated from each other, with at least one internal frame on the internal tube (generally frames on both tubes for union with the strip in a "V"), and that includes a centering or separating gasket, such as the one mentioned. This centering gasket will be between the ends of both tubes, on at least one side. In this way, when supporting them, the gaskets Both sections come into contact and ensure the tightness of the joint.
    [0042] Other variants will be discussed at other points in the memory.
    [0044] DESCRIPTION OF THE DRAWINGS
    [0046] For a better understanding of the invention, the following figures are included.
    [0048] Figure 1 represents a detailed section of an isolated conduit with an example of the joint of the invention.
    [0050] Figure 2.- Represents a perspective view of a fragment of another example of the centering joint.
    [0052] MODES OF CARRYING OUT THE INVENTION
    [0054] An embodiment of the invention is briefly described below, as an illustrative and non-limiting example thereof.
    [0056] Figure 1 shows a first example of embodiment, applied to a duct that has an inner tube (1), an outer tube (2), concentric, and an intermediate layer of insulating material (3).
    [0058] It can be seen that the tubes (1,2) have respective frames (11,21) that give rigidity to the joint and that are prepared to allow fixing to the adjacent duct section. Through this space you can access the insulating material (3), which is usually slightly removed to facilitate handling and fixing the tubes (1,2).
    [0060] As noted, during handling, the inner tube (1) tends to crush the bottom of the insulating material (3) and extend the top. To avoid this, uza a dinra ora ea nvenc n, which is reproduced in ms ea e in figure 2.
    [0062] As especially seen in Figure 2, which represents a small piece of centering gasket (4), it has a "T" section, with a longitudinal part (41), preferably arrow-shaped to facilitate insertion, and a The cross part (42) that acts as a stop in the introduction This cross part (42) serves in turn to rest on the centering joint (4) of the adjacent section and to ensure the tightness of the joint. crossed (42)
    [0064] It is preferred to place saw teeth (43) on one of the faces of the longitudinal part (41) to improve its fixation and increase the anchoring stop (Figure 2). Those teeth (43) will be, in use position, oriented towards the outer tube (2).
    [0066] At the junction between the longitudinal part (41) and the crossed part (42) there is a throttle (44), the function of which is visible in figure 1, that is, serving as an anchor point on the inner frame (11), of the inner tube (1). Therefore, it will be oriented (in use) towards it.
    [0068] The centering seal (4) will have a general shape corresponding to the measurements of the space between the tubes (1,2), to make placement easier. However, it is also possible to present the centering seal (4) as a roll material that is placed and cut at the time of application. This roll would be marketed in various widths to correspond to the available gaps. This system is less preferred, because it offers less resistance, but in return reduces the stock and reduces manufacturing costs.
    [0070] The material of the centering seal (4) will be elastic, but not too soft. For example, you can use rubber or another type of rubber.
