Detailed ways

The core of the invention is to provide a pipe repairer which can easily and efficiently achieve the plugging of the pressure relief hole, thereby improving the operation efficiency of the pipe repairer and reducing the operation difficulty.

The present invention will be further described in detail below in conjunction with the drawings and embodiments.

Please refer to FIG. 1. FIG. 1 is a cross-sectional view showing the assembled structure of a pipe repairer according to an embodiment of the present invention.

In a specific embodiment, the pipeline repairer provided by the present invention comprises a casing 11 having a pressure relief hole 12, and the outer end of the pressure relief hole 12 is openably provided with a stuff cover 13 and a cover The bottom of the 13 has a seal 131 that fits the pressure relief hole 12.

During the assembly and use process, when there is pressure in the repaired pipe 21, the boring cover 13 is first opened moderately, so that a certain gap is formed between the sluice cover 13 and the pressure relief hole 12, so that the pipe 21 is released, and then the casing is released. 11 A repairing operation is performed at a corresponding position of the damaged pipe 21, and after the repair is completed, the stuffing cover 13 and the pressure releasing hole 12 are reclosed to block the pressure releasing hole 12 through the sealing member 131. The whole operation process is simple and easy, the operation difficulty is low, and the operation efficiency is high.

Further, the stuffing cover 13 is detachably provided to the outer end portion of the pressure relief hole 12 by the fastener 14 . The opening and closing of the stuffing cover 13 is realized by the elastic disassembly and assembly of the fastener 14 , and the cooperation efficiency between the stuffing cover 13 and the pressure releasing hole 12 can be further improved, and the operation difficulty is reduced, thereby further improving the use of the pipe repairer. Sex.

More specifically, the outer peripheral portion of the pressure relief hole 12 has a plurality of threaded holes 121, and the fasteners 14 are screws that penetrate the stuffer cover 13 from the outside and are in one-to-one correspondence with the threaded holes 121 and are screw-fitted. During the actual operation, the screw is reversely screwed to form a certain gap between the stuffing cover 13 and the pressure releasing hole 12, and the sealing member 131 is disengaged from the pressure releasing hole 12, thereby ensuring the pressure balance between the inside and the outside of the pipe 21 during the operation. After the repairing operation is completed, the screw is screwed forward to re-align the threaded hole 121 with the pressure releasing hole 12, and the sealing member 131 and the pressure releasing hole 12 are fitted and sealed, thereby further reducing the suffocating cover 13 and releasing pressure. The operational difficulty of the mating structure between the holes 12 and the overall operational efficiency of the pipe repairer are correspondingly improved.

Further, the seal 131 is a seal ring. The sealing ring has good structural matching with the pressure relief hole 12, and the sealing effect is better.

It should be noted that the sealing member 131 is only a preferred embodiment. In practical applications, the sealing member 131 can also be a structural member such as a sealing gasket or a sealing block capable of sealing and sealing against the pressure relief hole 12, In principle, as long as it can meet the actual use requirements of the pipe repairer.

On the other hand, the housing 11 includes an upper housing 111 and a lower housing 112 that are coupled to each other, and the upper housing 111 and the lower housing 112 are removably connected by a fitting, and the pressure relief hole 12 is located in the upper housing. The middle of the body 111. The pressure relief hole 12 is disposed in the middle of the upper casing 111 to facilitate the timely discharge of the high pressure gas in the pipe 21 to further improve the pressure relief efficiency and the pressure relief effect of the pressure relief hole 12.

In addition, the fitting includes a bolt 113 that sequentially penetrates the side wall of the upper casing 111 and the side wall of the lower casing 112, and a nut 114 that is threadedly engaged with the bolt 113. The screw assembly structure of the bolt 113 and the nut 114 is easy to assemble and disassemble, and the structure is simple and reliable, and the operation efficiency of the pipe repairer can be further improved.

Further, the inner wall of the pressure relief hole 12 has a mounting thread (not shown). In the actual operation process, if special working conditions are required, other structural components such as a bulkhead or an external pipe fitting, which need to be fitted with the pressure relief hole 12, may be added to the pressure relief hole 12 through the installation thread, thereby further improving the pipeline repairer. Adaptability and structural adaptability.

Please refer to FIG. 2 and FIG. 3 . FIG. 2 is a cross-sectional view showing an assembly structure of a pipe repairer having an internal thread provided by a cover according to an embodiment of the present invention; FIG. 3 is a cover provided by an embodiment of the present invention; A cross-sectional view of the assembled structure of a pipe repairer with internal threads.

The boring cover 13 is provided with a boss 132, and the pressure relief hole 12 extends through the boss 132. Specifically, in practical applications, the mounting thread may be an external thread 152 disposed on the outer circumferential surface of the boss 132 as shown in FIG. The internal thread 151 provided on the inner wall of the pressure relief hole 12 is shown. In actual operation, the pipe repairer may need to be assembled and connected with different specifications of external pipe fittings to meet the needs of use under different working conditions. At this time, the external thread 152 or the internal thread 151 and the pipe fittings of different specifications may be adopted. Thread fitting and reliable assembly to ensure pipe joint stability and improve the adaptability of the pipe repairer.

In summary, in the pipeline repairer provided by the present invention, during the assembly and use process, when there is pressure in the repaired pipeline, the boring cover is appropriately opened to form a certain gap between the smear cover and the pressure relief hole. In order to relieve the pressure of the pipeline, the casing is installed at the corresponding position of the damaged pipeline to perform the repairing operation. After the repair is completed, the stuffing cover and the pressure relief hole are reclosed to seal the pressure relief hole through the sealing member. The whole operation process is simple and easy, the operation difficulty is low, and the operation efficiency is high.
