DETAILED DESCRIPTION
[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0021] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings. In each of the accompanying drawings, the same reference numerals represent the same or corresponding technical features. Each of the accompanying drawings is only a schematic diagram and is not necessarily drawn according to the actual scale.
[0022] The structural diagram of the first embodiment of the plugging device for a flexible belt pipeline of the utility model and the structural diagram of the flexible belt pressure sealing structure of the plugging device for a flexible belt pipeline of the utility model are as follows: Figure 1 and Figure 2 As shown, the device mainly includes three major components: a flexible belt 1, a flexible belt pressure sealing structure and a pressure piece. Among them, the flexible belt pressure sealing structure is composed of at least two screws 3 and a base 2, a pressing plate 4, a movable plate 5 and a bracket 6 connected in sequence along the extension direction of the screw 3. The pressing plate 4, the movable plate 5 and the bracket 6 are sleeved on the screw 3. The base 2 is fixedly connected to the screw 3 and one end of the flexible belt 1. The same sides of the pressing plate 4, the movable plate 5 and the bracket 6 are respectively connected with a flexible belt locking block 8, a flexible belt fixing rod 10 and a cross bar 11. The other end of the flexible belt 1 passes through the gap between the pressing plate 4 and the flexible belt locking block 8 from the bottom end of the pressing plate 4, then bypasses the cross bar 11 and is connected to the flexible belt fixing rod 10. The bracket 6 is fixedly connected to the pressure piece.
[0023] like Figure 1 and Figure 2 As shown, when a pressure vessel or pipeline leaks, the length of the flexible belt 1 is roughly determined according to the diameter of the pipe opening at the leaking position, and the base 2, the pressing plate 4, the moving plate 5 and the bracket 6 are all assembled on the screw 1, and the device is moved to the vicinity of the leaking point. One end of the flexible belt 1 is bound to the base 2, and the other end of the flexible belt 1 is passed from the bottom end of the pressing plate 4 through the gap between the pressing plate 4 and the flexible belt locking block 8, and then bypasses the cross bar 11 and is connected to the flexible belt fixing rod 10. The other end of the flexible belt 1 can be directly bound to the base 2, or bypassed. After one circle, the flexible belt fixing rod 10 is bound to itself, so that the flexible belt 1 is wrapped around the leaking point of the pipeline, and then the flexible belt 1 is moved horizontally to the leaking point and covers the leaking point, and the movable plate 5 is pressed downward by the pressure-applying member, and the flexible belt fixing rod 10 connected to the movable plate 5 pulls the flexible belt 1 down to achieve the purpose of tightening the flexible belt 1, and finally, by screwing the top screw 9, the flexible belt locking block 8 and the pressing plate 4 move relative to each other and clamp the flexible belt 1, and at the same time fix the current position of the pressing plate 4, to establish a new sealing structure to achieve rapid leak plugging in the pipeline.
[0024] As an implementation mode, during plugging, the flexible belt 1 may also be a fixed belt or a fixed belt with adhesive, depending on the leakage situation of the pipeline.
[0025] See also Figure 3 and Figure 4 As an optional implementation, a tension monitoring device is fixed to one side of the movable plate 5 connected to the flexible belt fixing rod 10 , and the tension sensing end of the tension monitoring device is connected to the flexible belt fixing rod 10 .
[0026] In this embodiment, a tension monitoring device is added to detect the tension value of the flexible belt 1. Under the condition of ensuring the sealing effect, the force on the flexible belt 1 is controlled within the strain range of the flexible belt 1 material, thereby improving the sealing effectiveness. In this embodiment, the flexible belt fixing rod 10 fixed to the tension monitoring device is tilted upward, and the corresponding tension monitoring device is also installed in an upward tilt so that the tension sensing end of the tension monitoring device is consistent with the direction of the flexible belt fixing rod 10.
[0027] As an optional implementation, when glue injection is used for sealing, the flexible belt 1 is set at the gap leakage of the flange, gland, etc. according to the above steps, and the glue injection plug 16 connected to the flexible belt 1 is aligned with the leakage point.
[0028] See also Figure 2 , the injection ports of the flexible belt 1 are evenly distributed and the injection plugs 16 are installed, the injection gun 15 is connected to the injection plugs 16, and the hydraulic oil pump 14 and the injection gun 15 are connected and then the glue is injected under pressure. After the injection is injected under pressure, the injection plugs 16 are blocked by the injection nut and the injection port cap.
[0029] Figure 3 and Figure 4 As an optional embodiment, the sides of the pressing piece 4 and the flexible belt locking block 8 are provided with threaded holes, and the flexible belt locking block 8 is connected to the pressing piece 4 through the top screw 9. By screwing the top screw 9, the flexible belt locking block 8 and the pressing piece 4 move relative to each other and clamp the flexible belt 1, maintaining the pressure of the flexible belt 1 on the pipeline, and at the same time, the top screw 9 is further screwed in and closely attached to the outer surface of the screw 3 to complete the fixing of the position of the pressing piece 4.
[0030] As an optional embodiment, the opposite end surfaces of the base 2 and the pressing sheet 4 adopt mutually interlocking arc structures, and the bottom end surface of the pressing sheet 4 is an arc structure convex toward the base 2. The other end of the flexible belt 1 passes through the pressing sheet 4 from the bottom end of the pressing sheet 4. In order to prevent the contact surface of the pressing sheet 4 and the flexible belt 1 from scratching the flexible belt 1 during the tensioning process, the bottom end of the pressing sheet 4 adopts a convex arc structure.
[0031] As an optional implementation, the pressure-applying member is a hydraulic jack 12, and the force-applying end of the hydraulic jack faces the moving plate 5. The hydraulic jack is connected to a hydraulic oil pump 14 via a high-pressure hose 13.
[0032] As an optional embodiment, the position of the bracket 6 is limited by a fixing nut 7 .
[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
