[0031] Example

[0032] Reference Figures 1-3 This utility model provides an instrument pipe plug device that is easy to install, including a device body 100, wherein the device body 100 has a first connecting plate 101 and a second connecting plate 102 that are arranged opposite to each other;

[0033] An assembly port 1011 is provided on the first connecting plate 101, and a threaded hole is provided on the second connecting plate 102;

[0034] A threaded rotating rod 400 is screwed onto the threaded hole, and a sealing assembly is provided at one end of the threaded rotating rod 400 facing the first connecting plate 101;

[0035] A pipe clamp 200 is provided inside the main body 100 of the device. The pipe clamp 200 includes an upper pipe clamp 201 and a lower pipe clamp 202. The upper pipe clamp 201 and the lower pipe clamp 202 cooperate to clamp the pipeline 900. The opening of the pipeline 900 is sealed by rotating the threaded rotating rod 400.

[0036] In some embodiments, the main body 100 of the easy-to-install instrument pipe plug device has two opposing first connecting plates 101 and second connecting plates 102, with a gap between the first connecting plates 101 and the second connecting plates 102.

[0037] The assembly port 1011 provided on the first connecting plate 101 is correspondingly provided with the threaded hole provided on the second connecting plate 102.

[0038] Instrument line 900 is inserted through assembly port 1011, and pipe clamp 200 holds instrument line 900, fixing the main body 100 of the device onto instrument line 900. By rotating threaded rod 400, the sealing component on threaded rod 400 moves toward the opening of pipe 900 and abuts against pipe 900. The sealing component then seals the opening of pipe 900, thus achieving the sealing of the pipe opening of instrument line 900 to be pressure tested, improving the sealing efficiency of pipe opening of instrument line 900, and improving construction efficiency.

[0039] In an optional embodiment, the sealing assembly includes a sealing body 600, and an inner groove 700 is provided on the sealing body 600, the inner groove 700 facing the first connecting plate 101.

[0040] In an optional embodiment, a rubber gasket is provided inside the inner groove 700.

[0041] In some embodiments, the sealing body 600 of the sealing assembly has an inner groove 700, which is circular; and the inner diameter of the inner groove 700 is larger than the outer diameter of the pipe opening of the pipeline 900; the pipe opening of the pipeline 900 can be inserted into the inner groove 700; since the inner diameter of the inner groove 700 is larger than the outer diameter of the pipe opening of the pipeline 900, this easy-to-install instrument pipe plugging device can be used for sealing pipe openings of various different specifications of pipelines 900.

[0042] To further improve the sealing performance, a rubber gasket is installed in the inner groove 700. The rubber gasket further improves the sealing performance between the pipe opening of the pipeline 900 and the sealing body 600.

[0043] The rubber gasket can be made of PTFE, while the main body 100, bolts, and threaded rod 400 are all made of stainless steel.

[0044] In an optional embodiment, the threaded rod 400 is provided with a rotating handle 500.

[0045] In order to enable the threaded rod 400 to rotate better, a rotating handle 500 is provided on the threaded rod 400. By rotating the handle 500, the threaded rod 400 is rotated, and the sealing assembly moves back and forth along the axial direction of the threaded rod 400, thereby achieving the sealing of the pipe opening of the pipeline 900.

[0046] In an optional embodiment, the upper tube clamp 201 is provided with an upper groove 2011, and the lower tube clamp 202 is provided with a lower groove 2021 corresponding to the upper groove 2011;

[0047] The upper groove 2011 and the lower groove 2021 cooperate to clamp the pipeline 900.

[0048] In some embodiments, the upper pipe clamp 201 has an upper groove 2011 and the lower pipe clamp 202 has a lower groove 2021; the upper groove 2011 and the lower groove 2021 cooperate to clamp the pipeline 900, thereby fixing the pipe clamp 200 to the pipeline 900, and thus fixing the instrument pipe plug device that is easy to install onto the pipeline 900.

[0049] In an optional embodiment, the upper end face of the lower tube clamp 202 is provided with two first threaded holes 2022, and the lower groove 2021 is provided between the two first threaded holes 2022.

[0050] In an optional embodiment, the lower end face of the upper tube clamp 201 is provided with an upper through hole that corresponds one-to-one with the first threaded hole 2022;

[0051] The bolt is inserted from the upper end of the upper pipe clamp 201 into the upper through hole and then screwed into the first threaded hole 2022.

[0052] In some embodiments, the lower tube clamp 202 has two first threaded holes 2022, and the upper tube clamp 201 has two upper through holes; the bolt is inserted from the upper end of the upper tube clamp 201 into the upper through holes and screwed into the first threaded holes 2022.

[0053] Adjust the distance between the upper pipe clamp 201 and the lower pipe clamp 202 by rotating the bolt, so that the upper pipe clamp 201 and the lower pipe clamp 202 can better clamp the pipeline 900.

[0054] In an optional embodiment, the device body 100 has an assembly groove 800; the pipe clamp 200 is inserted into the assembly groove 800 from one side of the assembly groove 800.

[0055] In an optional embodiment, a fly-off chain 300 is also included, one end of which is connected to the upper pipe clamp 201 and the other end is connected to a fixed object.

[0056] In an optional embodiment, a limiting plate 2023 is provided on the lower tube clamp 202, and the limiting plate 2023 is engaged outside the assembly slot 800 and abuts against the device body 100.

[0057] In order to ensure that the opening of the pipeline 900 corresponds with the sealing component, the pipe clamp 200 is assembled in the assembly slot 800. The pipe clamp 200 can move within a certain range relative to the main body 100 of the device, thereby ensuring that the sealing component corresponds with the opening of the pipeline 900 and that the sealing component can seal the opening of the pipeline 900.

[0058] To prevent the easily installed instrument pipe plug from splashing, an anti-flying chain 300 is installed on the upper pipe clamp 201. The anti-flying chain 300 is connected to a fixed object; the fixed object is a large object or a stationary object around the instrument pipeline. This can prevent the easily installed instrument pipe plug from splashing due to excessive pressure at the pipeline opening or the pipe clamp 200 not being secure, thus avoiding safety accidents.

[0059] A limiting plate 2023 is provided on the lower pipe clamp 202. The limiting plate 2023 cannot enter the assembly slot 800, thus fixing the pipe clamp 200 in the assembly slot 800.

[0060] The pipe clamp 200 of the instrument pipe plugging device provided by this utility model can be clamped on the pipeline 900, and the plugging component can be sealed by rotating the threaded rod 400, thus sealing the pipe opening of the instrument pipeline 900 to be pressurized; compared with the prior art, the plugging efficiency is improved and the construction efficiency is guaranteed.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
