DETAILED DESCRIPTION
[0020] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.
[0021] like Figures 1 to 4 As shown, a prefabricated foamed PVDF elbow soft insulation sleeve comprises an insulation sleeve body 1, a fixing component 2 and an insulation component 7. An opening 101 is arranged at the front end of the insulation sleeve body 1. Since the insulation sleeve body 1 is made of an arc-shaped aluminum foil insulation layer, it can improve the anti-ultraviolet and anti-weathering capabilities, thereby improving the service life of the insulation sleeve. The fixing component 2 is located at both ends of the opening 101. The fixing component 2 comprises a binding rope 201 and a constriction port 202. Two groups of constriction ports 202 are fixed at both ends of the insulation sleeve body 1, and binding ropes 201 are arranged on the inner sides of the two groups of constriction ports 202. The insulation sleeve body 1 is fixed to the elbow by the binding rope 201, so as to avoid displacement and dislocation of the pipeline insulation sleeve when it is used for a long time or subjected to a slight collision, which is beneficial to improving the stability of the device.
[0022] An extension ring 3 is provided at the central part of the insulation sleeve body 1, and the extension ring 3 is in a foldable and shrinkable shape, which can shrink and deform, thereby improving the fit between the insulation sleeve body 1 and the elbow, and can adapt to elbows of different angles. Four groups of anti-skid buckles 4 are provided on the outside of the insulation sleeve body 1, and four groups of fastening belts 5 are provided around the outer wall of the insulation sleeve body 1. When the fastening belts 5 are fastened with the anti-skid buckles 4, the insulation sleeve body 1 is contracted and squeezed inwardly to further fix the insulation sleeve body 1, and the gap between the insulation sleeve and the elbow can be reduced to improve the thermal insulation of the insulation sleeve. Six groups of anti-skid pads 6 are equidistantly arranged, and the inner side of the anti-skid pads 6 fits with the outer side of the pipe. Anti-skid pads 6 are provided between the insulation component 7 and the pipe. The material of the anti-skid pads 6 is rubber. By providing multiple groups of anti-skid pads 6, the friction between the insulation sleeve and the elbow can be increased, thereby avoiding sliding of the contact surface between the pipe and the insulation sleeve.
[0023] The insulation component 7 is located between the insulation sleeve body 1 and the pipe, and the insulation component 7 includes insulation cotton 701, metal wire 702, insulation layer 703 and wear-resistant layer 704. The insulation cotton 701 is glued to the inner side of the memory of the insulation sleeve body 1. The insulation cotton 701 is made of glass fiber material and is used to reduce the influence of the external environment temperature on the elbow. The metal wire 702 is glued to the inner side of the insulation cotton 701. The metal wire 702 can maintain the overall shape of the insulation layer 703, so that the entire insulation layer 703 can be bent into a required shape, and the metal wire 702 A thermal insulation layer 703 is arranged on the inner side, and the material of the thermal insulation layer 703 is filled with aerogel, which is used to further prevent the heat loss inside the elbow. A wear-resistant layer 704 is arranged on the inner side of the thermal insulation layer 703, and the wear-resistant layer 704 is woven with polyester fiber. The polyester fiber has good wear resistance and can fit the elbow completely, which can improve the thermal insulation of the thermal insulation cover. Because the thermal insulation cover body 1 forms a disassembly structure through the opening 101, the anti-slip buckle 4, the fastening belt 5 and the fixing component 2, the structure is simple, which is convenient for installation and disassembly of the thermal insulation cover, and the convenience of the device is improved.
[0024] In summary, when this kind of prefabricated foamed PVDF elbow soft insulation cover is used, first, the elbow is put into the insulation cover body 1 through the opening 101, and the protective cover body 1 is dragged to a suitable position. During the dragging process, the extension ring 3 is deformed to make the insulation cover body 1 fit the arc edge of the elbow, and the two ends of the binding rope 201 are stretched outward to make the closing opening 202 shrink inward and tie a knot, so that the two ends of the insulation cover body 1 are fixed on the elbow. At this time, the fastening belt 5 is contracted inward, and the fastening belt 5 passes through the anti-slip buckle 4 and is buckled with the anti-slip buckle 4. By controlling the position of the anti-slip buckle 4 on the fastening belt 5, the insulation cover body 1 is compressed toward the opening 101 to close the opening 101. At the same time, due to the bundling of the fastening belt 5, the gap between the insulation cover body 1 and the elbow is reduced, and at this time, the anti-slip pad 6 inside the insulation cover body 1 is tightly fitted with the elbow, thereby preventing the insulation cover body 1 from shifting.
