Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of thermal insulation pipes, and in particular relates to a prefabricated thermal insulation pipe with an inner support. Background Art
[0002] At present, there are two types of domestic heating pipe insulation: prefabricated insulation and on-site insulation. However, prefabricated insulation only insulates the pipe, not the bracket. In the actual installation process of the bracket of the prefabricated insulation pipe, it is necessary to destroy the insulation layer and the outer sheath pipe, weld the bracket to the working core pipe, and then add the insulation layer and the outer sheath to the bracket. This method causes heat to be easily lost due to the loose connection between the inner and outer insulation layers. The heat loss is caused by the thermal bridge effect of the bracket due to the inadequate insulation measures for the bracket. Because the insulation material is inconsistent with the pipe insulation material and the newly made insulation is difficult to fit tightly, it will increase the heat dissipation of the bracket. Therefore, it is difficult to achieve efficient thermal insulation of the pipeline. Utility Model Content
[0003] The utility model aims to provide a prefabricated thermal insulation pipe with internal support to solve the problems existing in the background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a prefabricated thermal insulation pipe with internal support, comprising a steel pipe, an outer protective pipe and a polyurethane protective layer, the polyurethane protective layer is arranged between the steel pipe and the outer protective pipe, a vertical support beam is welded at the bottom of the steel pipe, an internal arc flange is welded at the bottom of the vertical support beam, an external arc flange is arranged at the lower part of the outside of the outer protective pipe, the external arc flange and the internal arc flange are fixed by bolts, and a base is welded at the bottom of the external arc flange.
[0005] Preferably, heat insulation cotton is provided between the inner arc-shaped flange and the outer protective tube.
[0006] Preferably, heat insulation cotton is provided between the outer arc-shaped flange and the outer protective tube.
[0007] Preferably, the cross-section of the vertical support beam is I-shaped.
[0008] Preferably, the vertical support beam and the corresponding inner arc flange are spaced apart in the polyurethane protective layer.
[0009] The beneficial effects of the utility model are as follows: the device has a simple structure and will not damage the insulation pipe. The vertical support beam and the internal arc flange are prefabricated and installed between the steel pipe and the outer protective pipe before the insulation pipe is foamed. During on-site construction, the base with the external arc flange is directly aligned with the position of the internal arc flange and fixed with bolts, which will not cause heat loss. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a cross-sectional view of the present invention. DETAILED DESCRIPTION
[0011] In the description of the present disclosure, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present disclosure.
[0012] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present disclosure, unless otherwise specified, "plurality" means two or more.
[0013] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.
[0014] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.
[0015] like Figure 1 As shown, the utility model discloses a prefabricated thermal insulation pipe with internal support, comprising a steel pipe 1, an outer protective pipe 2 and a polyurethane protective layer 3, wherein the polyurethane protective layer is arranged between the steel pipe and the outer protective pipe, and a vertical support beam 4 is welded at the bottom of the steel pipe, wherein the vertical support beam and the corresponding internal arc flange are arranged in the polyurethane protective layer at intervals, and the vertical support beam plays a role in reinforcing the steel pipe and the outer protective pipe. When there is liquid in the steel pipe, gravity will squeeze the polyurethane protective layer downward, and since the existing base will act on the outer protective pipe, the bottom of the steel pipe will squeeze the polyurethane protective layer under the action of gravity, causing it to deform and maintain. In order to prevent the above situation from occurring, the vertical support beams are arranged at intervals on the outer side of the bottom of the steel pipe, and four can be in a group. The cross-section of the vertical support beam is I-shaped, and it forms a module with the internal arc flange and is arranged at intervals, so that the above situation can be avoided.
[0016] Furthermore, an internal arc flange 5 is welded to the bottom of the vertical support beam, and an external arc flange 6 is provided at the lower part of the outer protective pipe. The external arc flange and the internal arc flange are fixed by bolts 7. Specifically, a hole is opened at a position corresponding to the flange hole of the internal arc flange on the outer protective pipe, and an internal thread is prefabricated on the flange hole of the internal arc flange. The bolts can pass through the flange hole of the external arc flange and the flange hole of the outer protective pipe and the internal arc flange to be threaded together. In order to support the thermal insulation pipe as a whole, a base 8 is welded to the bottom of the external arc flange. The upward supporting force of the base is transmitted through the external arc flange and the internal arc flange, and directly acts on the internal steel pipe through the vertical support beam, which can effectively avoid the deformation of the thermal insulation pipe. Since they are all prefabricated structures, it is only necessary to fix the base with the external arc flange to the bottom of the outer protective pipe with bolts during on-site construction.
[0017] Furthermore, in order to prevent heat transfer and loss, heat insulation cotton is provided between the inner arc-shaped flange and the outer protective tube. Heat insulation cotton is provided between the outer arc-shaped flange and the outer protective tube.
[0018] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
