New description: [New technical field] This is a protective cover for flanges, especially one that is suitable for installation on the joint, valve body and flange to easily find or confirm flange leakage. Protective cover. [Prior Art] In pipes for generally conveying fluids, flanges are widely used to connect pipes. When the flange is corroded by fluids (acid, alkaline, corrosive fluids or similar chemicals) in the pipeline or if it ages, the transport fluid in the pipeline will leak out of the flange. Splashes of corrosive fluids or high pressure gases leaking from the flange may damage the site builder or the inspector. In order to prevent and detect the leakage of the transport fluid or chemical due to the failure of the flange connection, a safety jacket has been proposed to cover the outside of the flange. However, the conventional flange has a complicated structure of the safety sheath, is inconvenient to install, and has a defect that the discharge fluid or chemical substance in the pipeline cannot be effectively prevented from being ejected. [New content] In view of this, the creator has carefully studied and analyzed the design and design, and has created this creation. Therefore, the main purpose of this creation is to provide a protective sleeve for the flange that can be quickly and simply wrapped around the outside of the flange to prevent and detect the transport of fluid or chemistry due to failure of the flange connection 3 The material leakage is sprayed out; at the same time, the protective cover has excellent anti-corrosion, anti-oxidation, waterproof, heat-resistant and other special modifications applicable to pipeline flanges such as acid concentration, corrosive fluid, high-pressure steam, etc. The protective cover has the advantage of being simple in structure. The protective cover of the present invention comprises a belt-like body and first and second straps. The strip-shaped body is configured to be wound around an outer circumference of a flange of a connecting pipe, the body comprising a first end and a second end spaced apart in a length direction, the body being provided with at least a support on the support piece and A leak detecting piece is disposed between the body, and the body or the supporting piece has a through hole, and both sides of the body have a rope hole extending along the length direction and passing through the first end and the second end of the body. The first and second straps individually pass through the cord holes on either side of the body along the length. After the body loop is wrapped around the outer periphery of the flange, the individual fastening of the first and second straps can be utilized to engage the body on the flange. When the body coil is wound around the outer periphery of the flange and fluid leakage occurs in the flange, the < leakage fluid passes through the perforation and contacts the leak detecting piece, so that the leak detecting piece is discolored. In one embodiment, the body is provided with a slot extending along the length, and the body is sewn with a transparent sheet disposed on the inner surface of the body and covering the slot. A plurality of support sheets are disposed on the inner surface of the body. A leak detecting sheet is disposed between each of the supporting sheets and the body, and the through holes are provided on the respective supporting sheets. In an embodiment, the protective cover further comprises a frame-shaped elastic piece, the elastic piece, the transparent piece and the plurality of supporting pieces are sequentially covered on the inner surface of the body and are stitched together with the suture on the body. Upper, the elastic piece has a groove corresponding to the slot. Preferably, the body comprises a body, and the body comprises a central portion and two side portions extending outward from both side edges of the central portion, the central portion having the slot, the two sides facing the central portion The central portion is folded over; when the two side portions are folded on the central portion, the transparent sheet, the number of support sheets, and the elastic sheet are sewn to the body by sutures. Other objects, advantages and features of the present invention will be apparent from the description of the preferred embodiments illustrated herein DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described by way of example only, but not by way of limitation. The protective cover 10 is constructed by the specific embodiment, and the protective cover 10 is provided around the flange, the expansion joint, the valve body and the flange of the connection to detect and prevent the chemical substance from being discharged due to the failure of the flange connection. . It is shown in Figures 5 and 6 that the boot 10 is wrapped over the outside of the flange 14 connecting the two conduits 12. The protective cover 10 includes a belt-shaped body 16, a first binding rope 18, 5 M428288 and a first 'home rope 20. The body 16 is made of a single layer or a plurality of layers of chemical resistant cloth, and the chemical resistant cloth can be made of high strength polytetrafluoroethylene expanded (PTFE), polyethylene (PE), polypropylene (pp), and gas. Ethylene (pvc) and the like] Among them, polytetrafluoroethylene expanded (PTFE) has excellent properties such as anti-corrosion, acidity, water resistance, and smoke resistance. The body 16 includes a first end 22 and a second end 23 spaced apart in a longitudinal direction, and a first side 24 and a second side 25 spaced apart in the width direction. The first end 22 and the second end 23 are individually provided, for example. The attachment member 26' of the fastening strip allows the body 16 to be looped around the outer periphery of the flange 14 and can be snapped into position by the connector 26 on the first end 22 and the second end 23 (see Figure 6). Further, the body 16 is provided with a slot 28 extending along the length direction, and the slot 28 is located at the center of the body 16. A transparent sheet 3 is further sewn on the body 16 for covering the slot 28. In this embodiment, the transparent sheet 3 is disposed on the inner surface 32 of the body 16 (ie, the body ι6 is in contact with the outer periphery of the flange 14). s surface). Furthermore, a plurality of support sheets 34 are bonded to the inner surface 32 of the body 16, and an L test piece (PH test paper) 38 is interposed between each support piece 34 and the body 16, and each support piece 34 is further provided for leakage. The perforations 36' through which the fluid passes allow the m fluid to contact the leak detection sheet 38 via the perforations 36. When the leak detecting sheet 38 comes into contact with an acidic or an expiratory leaking fluid, the leak detecting sheet 38 is discolored (e.g., red to represent acidity and green to alkaline). 6 As shown in the fourth figure, in the embodiment, the body 16 is formed by folding a piece of the body, and the piece includes a central portion 40 and two sides extending outward from both side edges of the central portion 40. The central portion 4 has the slot 28 formed therein, and the two side portions 42 are folded toward the central portion 40 to cover both sides of the central portion 40. After the two side portions 42 are pointed on the central portion 40, the transparent sheet 3, the number of support sheets 34, and a frame-shaped elastic sheet 44 are sequentially covered on the two side portions 42 of the body 16. The suture 46 is used to suture the body. The elastic piece 44 has a groove 48 corresponding to the slot 28, and the elastic piece 44 is coupled to the transparent piece 30 and the plurality of support pieces, so that the slit of the stitch 46 can be minimized. Thus, it is possible to effectively prevent leakage fluid from leaking from the seam of the suture 46. Furthermore, when the two side portions 42 are folded on the central portion 4 (), a rope for the first and second tie lines 18, 2 () to be individually passed is formed on both sides of the body 16. Hole 50. The first and second straps 18, 2 are individually passed through the cord holes 50 on both sides of the body 16 along the length direction, and the two ends of the first and second straps 18, 2 are engaged. The first end 22 and the first end 23 of the body 16 and the second tie 18, 2 () may be made of a Teflon CTeflon, an iron gas impregnated line, or a high strength fiber. Ben: The production side according to the set 1Q is used to wrap the body ring around the outer periphery of the flange 14, and the first end 22 and the second end μ of the M428288 connector 26 are used to buckle the positioning, and then, the first The first and second tie wires 18, 20 are fastened together to quickly and simply wrap the protective cover 1 against the outside of the flange 14 to provide excellent protection. When the protective cover 1 of the present invention is wrapped around the outer periphery of the flange 14, if the fluid or chemical in the pipe 12 leaks out due to the failure of the connection of the flange 14, the leakage fluid will pass through the perforation. The contact with the leak detecting piece 38 causes the leak detecting piece 38 to be discolored. On-site construction personnel or inspectors can easily find and/or confirm the leakage of the covered flange through the transparent sheet 30 and distinguish the acidity and alkalinity and leakage degree of the leaking fluid, so that the strain treatment can be quickly performed, and then the strain can be quickly performed. Avoid work safety incidents. The body 16 of the tamper resistant sleeve 10 can also be formed from a transparent sheet, such as Teflon. If the body 16 is made of a transparent material, the slot 16 may not be provided on the body 16, and the transparent sheet 30 may not be sewn on the body 16. Furthermore, the support sheet 30 provided with the leak detection sheet 34 may be disposed on the outer surface of the body 16; * When the support sheet 30 is disposed on the outer surface of the body 16, a through hole 36 for providing a leaking fluid is provided on the body 16 and Corresponds to the inside of the support piece 3〇.
