Description

Technical Field

[0001] The utility model relates to the technical field of pipe orifice plugging, in particular to a pipe orifice plugging device for a long-distance pipeline. Background Art

[0002] Long-distance pipelines are classified according to the properties of materials: they are divided into metal pipes and non-metallic pipes, and according to the properties of the transported media: water supply and drainage pipes, compressed air pipes, hydrogen pipes, gas pipes and acetylene pipes, etc. Gas pipelines are relatively easy to see in our daily production. The pipes connecting the gas inlet and the gas hood are usually soft pipes. During the gas pipeline laying and construction phase, they need to be inspected for leaks. During the inspection, it is usually necessary to seal the terminal gas hose, which requires the use of a plugger.

[0003] According to the utility model patent with the announcement number: CN213512644U, a long-distance pipeline pipe mouth plugger is disclosed, which relates to the field of a plugger, and has the following beneficial effects: through the structural design of the first pipe sleeve, the second pipe sleeve, the sliding rod, the sliding block, the bolt and the outer sealing plate, it is easy to install and disassemble, and the pipe mouth of the long-distance pipeline can be better fixed to prevent the device from shaking and falling off; through the structural design of the connecting block, the connecting spring, the movable rod, the telescopic rod, the rubber pad, the inner sealing plate and the sealing ring, the pipe mouth of the long-distance pipeline can be better sealed to prevent leakage at the pipe mouth.

[0004] Although the above technology can achieve the sealing and fixing effect of the pipe mouth, the installation method in the sealing mechanism is still not convenient enough, and there are many parts and components, which are easy to damage and increase the subsequent maintenance cost. At the same time, it can only be used for pipes of fixed sizes, and its use is relatively limited, so it needs to be improved.

[0005] Therefore, it is necessary to provide a new long-distance pipeline orifice plugging device to solve the above-mentioned technical problems. Utility Model Content

[0019] 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 of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the utility model. It is understandable that the drawings are only provided for reference and illustration, and are not used to limit the utility model. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0020] Please refer to Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of a long-distance pipeline orifice plugging device provided by the utility model; Figure 2 It is a structural schematic diagram of the protection mechanism in the utility model; Figure 3 A long-distance pipeline orifice plugger comprises a gas pipeline 1, a plugging mechanism 2 is arranged inside the gas pipeline 1, a protective mechanism is arranged at one end of the gas pipeline 1, the plugging mechanism 2 is used to plug the inside of the gas pipeline 1, and the protective mechanism is used to protect the plugging mechanism 2.

[0021] It should be noted that when in use, the blocking mechanism 2 is placed in the gas pipeline 1, and then an air pump is used to inflate the blocking mechanism 2 to expand the blocking mechanism 2, thereby achieving blocking of the pipe opening. The operation is convenient and can also be applied to gas pipelines 1 of different sizes. Then, the protective mechanism is installed at one end of the gas pipeline 1. The protective mechanism can prevent external factors from affecting the blocking mechanism 2.

[0022] In the specific implementation process, Figure 2 and Figure 3 As shown, the blocking mechanism 2 includes a blocking airbag 21 arranged inside the gas pipeline 1, an inflation head 22 is arranged on one side of the blocking airbag 21, a valve 23 is arranged on the outside of the inflation head 22, and the blocking airbag 21 is made of rubber.

[0023] It should be noted that: the blocking airbag 21 is placed into the gas pipeline 1, and then the air pump is connected to the inflation head 22, and then the valve 23 is opened to start the air pump to inflate the blocking airbag 21, and then the valve 23 is closed to separate the air pump from the inflation head 22. By inflating the blocking airbag 21, the blocking airbag is expanded and deeply fits with the inner wall of the gas pipeline 1, so that the gas in the gas pipeline 1 is blocked to achieve the purpose of blocking. Not only is the blocking speed fast and the operation is convenient, it can also be applied to pipelines of different sizes. At the same time, it has strong maneuverability. The blocking airbag 21 can be folded for storage at ordinary times, and only needs to be opened and inflated when used.

[0027] It should be noted that: after the inside of the gas pipeline 1 is sealed, the first protective plate 3 and the second protective plate 4 are moved so that the two are stuck on the outside of one end of the gas pipeline 1, so that the positioning rod 6 is stuck in the positioning hole 7. At this time, the four ear plates 5 are in a fit state, and then the fixing screws 9 are screwed into the threaded holes 8, so that the first protective plate 3 and the second protective plate 4 can be fixed. The first protective plate 3 and the second protective plate 4 can be used to protect the sealing mechanism 2 to prevent it from being damaged by external factors.

[0028] The working principle of the long-distance pipeline orifice plugging device provided by the utility model is as follows:
