Description

Technical Field

[0001] The utility model relates to the technical field of pipeline sealing devices, in particular to a sealing device for a pressure pipeline. Background Art

[0002] Pressure pipelines refer to all pipelines that are subjected to internal or external pressure, regardless of the medium inside the pipe. Due to the long-term high-pressure environment and the long laying distance of the pressure pipeline, it is inevitable that there will be very few leakage points during use. However, the causes of leakage points are various, so the size of the pipe where the leakage point occurs is also difficult to determine. Users need to carry sealing devices of various sizes to repair it in time, which is inconvenient and not easy to repair quickly. Utility Model Content

[0007] A further improvement is that a quick-insertion device is provided between the snap-fit square column and the plug-in square column to facilitate the user to quickly install the snap-fit square column.

[0008] A further improvement is that the quick-insertion device includes: a rounded corner provided on the engaging square column, and an oblique angle provided on the plug-in square column for matching with the rounded corner.

[0009] A further improvement is that the sealing device includes: a threaded seat arranged on the mounting seat, a threaded rod threadedly connected to the threaded seat, a resistance seat rotatably arranged on the threaded rod, and an arc-shaped plate arranged on the resistance seat through a limiting device.

[0010] Further improvements are as follows: the limiting device includes: at least two strip holes opened on the resistance seat, a threaded hole arranged on the arc plate, a limiting strip arranged on the resistance seat and perpendicular to the length direction of the strip hole, and a limiting groove opened on the arc plate and matching with the limiting strip.

[0011] A further improvement is that a handle for easy carrying is also provided on the plug-in square column.

[0018] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0019] like Figure 1-Figure 2 As shown, a sealing device for a pressure pipeline includes: a mounting base 1, a sealing device arranged on the mounting base 1 for sealing a leakage point of the pipeline, and a connecting belt 2 detachably arranged on the mounting base 1 through a connecting device, wherein the connecting device includes: a snap-fit square column 3 respectively hinged to both ends of the connecting belt 2, and the snap-fit square column 3 is detachably connected to the mounting base 1 through a snap-fit device.

[0020] In order to facilitate the fixation of the snap-fit square column 3, the snap-fit device includes: a snap-fit square groove 4 provided on the mounting seat 1 for inserting the snap-fit square column 3, a snap-fit hole 5 provided on the snap-fit square column 3, and an inserting square column 6 that can be slidably arranged on the snap-fit square groove 4 through an elastic driving device.

[0021] In order to facilitate the disassembly and assembly of the connecting belt 2, the elastic driving device includes: a locking channel 7 opened on the mounting seat 1 for the sliding of the plug-in square column 6, a mounting groove 8 opened on the mounting seat 1 and located at the same position as the locking channel 7, a resistance plate 9 arranged on the plug-in square column 6, a cover plate 10 arranged on the mounting groove 8, and a spring 11 sleeved on the plug-in square column 6, one end of which resists the resistance plate 9 and the other end of which resists the cover plate 10.

[0022] In order to facilitate the quick installation of the connecting belt 2, a quick-insertion device is also provided between the snap-fit square column 3 and the plug-in square column 6 to facilitate the user to quickly install the snap-fit square column 3. The quick-insertion device includes: a rounded corner 12 opened on the snap-fit square column 3, and an oblique corner 13 opened on the plug-in square column 6 for matching with the rounded corner 12.

[0023] In order to facilitate the replacement of curved plates 17 of various sizes and thus adapt to the sizes of various pipes, the sealing device includes: a threaded seat 14 arranged on the mounting seat 1, a threaded rod 15 threadedly connected to the threaded seat 14, a resistance seat 16 rotatably arranged on the threaded rod 15, and a curved plate 17 arranged on the resistance seat 16 through a limiting device.

[0024] In order to prevent the arc plate 17 from sliding after being locked by the screws, the limiting device includes: at least two strip holes 18 opened on the resistance seat 16, a threaded hole 19 arranged on the arc plate 17, a limiting strip 20 arranged on the resistance seat 16 and perpendicular to the length direction of the strip hole 18, and a limiting groove 21 opened on the arc plate 17 and matched with the limiting strip 20.

[0025] In order to facilitate the release of the engagement, a handle 22 is provided on the plug-in square column 6 for easy lifting.

[0026] In order to facilitate the rotation of the threaded rod 15 and thus compress the pipeline, the threaded rod 15 is further provided with a hand wheel 23 for easy rotation.

[0027] Working principle: Carry connecting belts 2 and curved plates 17 of various sizes, move to the leak point, and then select connecting belts 2 and curved plates 17 according to the diameter of the pipe;

[0028] When in use, first insert the snap-fitting square column 3 at one end of the connecting belt 2 into the snap-fitting square groove 4. At this time, the snap-fitting square column 3 resists the plug-in square column 6, driving the plug-in square column 6 to move so as to avoid the slipping space. When it moves to the position corresponding to the snap-fitting hole 5 and the plug-in square column 6, the plug-in square column 6 is reset under the action of the spring 11 to complete the snap-fitting. At this time, the user can put the connecting belt 2 on the pipe. After the sleeve is completed, the snap-fitting square column 3 at the other end of the connecting belt 2 can be inserted into the snap-fitting square groove 4 to complete the installation.

[0029] Then move to the location where the leakage occurs, turn the hand wheel 23, and control the curved plate 17 to press tightly against the leakage point to complete the plugging.

[0030] During disassembly, the handle 22 can be pulled up to release the engagement of the plug-in square column 6 with the engagement hole 5, and the connecting belt 2 can be released at this time.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only illustrate the principles of the present invention.
