[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0027] The ring 1 includes a first ring 101 and a second ring 102. One end of the first ring 101 is provided with an ear plate, and the other end is provided with a double ear plate. One end of the second ring 102 is provided with an ear plate, and the other end is provided with a rotating shaft. The first ring 101 is rotatably connected to the rotating shaft end of the second ring 102 through the double ear plate. The inner ring surfaces of the first ring 101 and the second ring 102 are provided with an annular groove for docking with the flange, and an elastic rubber ring 2 with a trapezoidal cross section is bonded inside the annular groove. The first ring 101 Semi-annular tubes are provided on both sides of the inner ring surface of the second ring 102, and an expansion liquid tube 103 is fixedly connected to the open side of the semi-annular tube. The interior of the expansion liquid tube 103 is connected to the elastic rubber ring 2 and the closed space between the first ring 101 and the second ring 102, and the closed space between the elastic rubber ring 2 and the first ring 101 and the second ring 102 is filled with flame retardant liquid. The interior of the first ring 101 is provided with a fluid through hole 104 connected from the annular groove to the outer annular surface.

[0028] During operation, the bolts connecting the first sleeve 101 and the second sleeve 102 are removed, and then the first sleeve 101 and the second sleeve 102 are pulled apart, and the first sleeve 101 and the second sleeve 102 are rotated and unfolded from the adapter end, and at the same time, the elastic rubber ring 2 is driven to be disconnected, and then the sealing colloid is applied to the disconnected part of the elastic rubber ring 2, and the unfolded first sleeve 101 and the second sleeve 102 are clamped at the interface position of the pipeline according to the position of the internal ring groove. During the clamping process, the disconnected elastic rubber ring 2 is spliced ​​and bonded together again, and then the sleeve 1 and the elastic rubber ring 2 are fixed by bolts, and after fixing, the elastic rubber ring is exhausted through the exhaust hole opened on the side of the sleeve 1. 2 and the pipeline interface. During the air extraction process, the elastic rubber ring 2 will surround and adhere to the surface of the flange plate, and then the flame-retardant stable liquid will be filled between the elastic rubber ring 2 and the first ring 101 and the second ring 102 through the injection hole opened on the side of the ring 1. The transition position of the first ring 101 and the second ring 102 is sealed, and then it can be used; during use, if there is leakage or gas leakage, the leaked liquid or gas will quickly push the elastic rubber ring 2 outward, and the elastic rubber ring 2 will push the filled stable liquid, so that the liquid enters the expansion liquid tube 103 through the branch hole, and the expansion liquid tube 103 will expand due to the filling and adhere to the surface of the flange plate.

[0029] In summary, through the arrangement of the first ring 101, the second ring 102, the expansion liquid tube 103 and the elastic rubber ring 2, when leakage occurs at the pipeline interface, the pressure of the leaking fluid can be used to press the elastic rubber ring 2 outward, so that the expansion liquid tube 103 can further expand and surround the flange interface, thereby achieving remedial treatment of the interface position and reducing energy loss.

[0030] Embodiment 2:

[0031] See also Figure 4 This embodiment provides a technical solution based on the first embodiment: the sounding structure 3 includes a mounting tube 301, a thread is provided on the side surface of one end of the mounting tube 301, and the mounting tube 301 is threadedly connected to the port of the fluid through hole 104 through the thread of the mounting tube 301, a one-way valve 302 is fixedly connected to the inside of the mounting tube 301 at one end close to the first ring 101, a striking rod 303 is slidably connected to the output end of the one-way valve 302 at intervals inside the mounting tube 301, a spring 304 is sleeved on the rod body of the striking rod 303, the other end of the striking rod 303 passes through the mounting tube 301 and the top is flush with the mounting tube 301, and a sounding piece 305 is fixedly connected to the end face of the mounting tube 301.

[0032] According to the above process, liquid or gas will flow toward the one-way valve 302 through the fluid through hole 104. When the pressure is sufficient, the one-way valve 302 will open and release a certain amount of liquid or gas, and then close again. The released liquid or gas will rush toward the striking rod 303, and the striking rod 303 will move along the mounting tube 301 to the position of the discharge hole and hit the surface of the sounding piece 305. When the liquid or gas inside the mounting tube 301 is discharged through the discharge hole, the striking rod 303 will reset under the action of the spring 304. This process is performed before and after the repair until the maintenance personnel close the pipeline to perform the repair.

[0033] In summary, by installing the tube 301, the one-way valve 302, the striking rod 303, the spring 304 and the sounding piece 305, the fluid through hole 104 can be coordinated with the pressure of the leaking fluid to push the striking rod 303 and impact the surface of the sounding piece 305, thereby generating a metal buzzing sound, which serves as a warning and guidance for the location of the leaking interface, so that the staff can find it in time and perform maintenance.

[0034] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0035] Working principle: When working, first remove the bolts connecting the first ring 101 and the second ring 102, then pull apart the first ring 101 and the second ring 102, the first ring 101 and the second ring 102 will rotate and unfold from the adapter end, and at the same time drive the elastic rubber ring 2 to be disconnected, and then apply sealing colloid to the disconnected part of the elastic rubber ring 2, and clamp the unfolded first ring 101 and the second ring 102 at the interface position of the pipeline according to the position of the internal ring groove, during the clamping process, the disconnected elastic rubber ring 2 will be spliced ​​and bonded together again, and then the ring 1 and the elastic rubber ring 2 are fixed by bolts, and after fixing, the air is evacuated between the elastic rubber ring 2 and the pipeline interface through the exhaust hole opened on the side of the ring 1, during the exhaust process, the elastic rubber ring 2 will surround and adhere to the surface of the flange plate, and then the flame retardant stable liquid is filled into the space between the elastic rubber ring 2 and the first ring 101 and the second ring 102 through the injection hole opened on the side of the ring 1. The transition position of the second ring 102 is sealed, and then it can be used; during use, if there is leakage or gas leakage, the exposed liquid or gas will quickly push the elastic rubber ring 2 outward, and the elastic rubber ring 2 will push the filled stable liquid, so that the liquid enters the expansion liquid tube 103 through the branch hole, and the expansion liquid tube 103 will expand due to the filling and stick to the surface of the flange plate, and then the liquid or gas will flow to the one-way valve 302 through the fluid through hole 104. When the pressure is sufficient, the one-way valve 302 will open and release a certain amount of liquid or gas, and then close again, and the released liquid or gas will rush to the striking rod 303, and the striking rod 303 will move along the mounting tube 301 to the position of the discharge hole, and hit the surface of the sounding piece 305. When the liquid or gas inside the mounting tube 301 is discharged through the discharge hole, the striking rod 303 will be reset under the action of the spring 304. This process is performed before and after the repair until the maintenance personnel close the pipeline to perform the repair.
