Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plugging devices, in particular to a flexible plug. BACKGROUND

[0002] In the process of gas transportation, gas pipelines are used for transmission. When the pipeline end needs to be plugged for disassembly and maintenance to avoid leakage of residual gas, a plugging device is generally used to plug the pipeline end. The outer periphery of the plug has external threads. When the plug is installed in one end of the gas pipeline, the plug needs to be connected to the gas pipeline by rotating the tool. When the one end of the plug deviates from the one end of the gas pipeline, the plug is continuously driven. Because the plug and the gas pipeline are relatively deviated, the external threads of the plug or the internal threads of the gas pipeline are damaged, thereby reducing the sealing between the plug and the gas pipeline. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at the defects and deficiencies of prior art, and provides a flexible plug.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0005] The utility model discloses a flexible plug, which comprises a plug body and a throat clamp, the plug body is made of flexible material, one end of the plug body is provided with a mounting hole, the outer end of the mounting hole is provided with a snap ring in the circumferential direction, the throat clamp is sleeved on the outer periphery of the plug body, the throat clamp can extrude the plug body and tighten the mounting hole, when the throat clamp is tightened, the inner side wall of the mounting hole is clamped on the periphery of the pipeline.

[0006] Preferably, the snap ring and the plug body are integrally arranged, and the plug body is made of flexible material.

[0007] Preferably, a stabilizing sheath is sleeved on one end of the plug body away from the mounting hole.

[0008] Preferably, a plurality of supporting rods are evenly arranged in the side wall of the plug body.

[0009] Preferably, a fixing disc is embedded in one end of the plug body away from the mounting hole, and one end of the plurality of supporting rods is evenly arranged on the periphery of the fixing disc.

[0010] Preferably, two driving rings are evenly arranged on one end of the plug body close to the opening of the mounting hole.

[0011] Preferably, a plurality of fixing blocks are evenly arranged on the inner periphery of the throat clamp.

[0012] In summary, the present application includes at least one of the following beneficial technical effects:

[0013] 1. When the pipe needs to be plugged, first loosen the throat, then insert one end of the pipe into the mounting hole until the end of the pipe abuts the bottom of the mounting hole, at which time the inner periphery of the ring abuts the side wall of the pipe, so that the plug body does not move during the driving of the throat, then drive the throat to clamp the side wall of the plug body, so that the inner side wall of the mounting hole abuts the pipe, thereby plugging the outlet of the pipe, then when the plug body needs to be removed, just loosen the throat, then the plug body can be removed from the pipe, so that the plug or the pipe is not damaged, and the sealing between the plug and the pipe remains unchanged.

[0014] 2. A plurality of struts are fixed to the fixed disc, and since the plug body is made of soft material, when the plug body is stored, it will not deform under the support of the plurality of struts, facilitating the plug body to be sleeved on one end of the pipe. BRIEF DESCRIPTION OF DRAWINGS

[0015] Figure 1 is a sectional view of the plug of the present application.

[0016] In the figure: 1, plug body; 2, throat; 3, mounting hole; 4, ring; 5, stabilizing sheath; 6, fixed disc; 7, strut; 8, driving ring; 9, fixed block. DETAILED DESCRIPTION

[0017] The present application will be further described below with reference to the accompanying drawings.

[0018] The present application discloses a flexible plug.

[0019] Referring to Figure 1 , including plug body 1 and throat 2, the vertical section of plug body 1 is in the shape of "N", throat 2 is sleeved and fixed to the outer periphery of plug body 1, one end of plug body 1 has mounting hole 3, the inner periphery of the opening end of mounting hole 3 is integrally provided with ring 4, the outer side of the periphery of ring 4 is provided with guide slope, plug body 1 and ring 4 are both made of flexible rubber.

[0020] Loosen the throat 2, then insert one end of the pipe into the mounting hole 3 until the end of the pipe abuts the bottom of the mounting hole 3, at which time the inner periphery of the ring 4 abuts the side wall of the pipe, so that the plug body 1 does not move during the driving of the throat 2, then drive the throat 2 to clamp the side wall of the plug body 1, so that the inner side wall of the mounting hole 3 abuts the pipe, thereby plugging the outlet of the pipe, then when the plug body 1 needs to be removed, just loosen the throat 2, then the plug body 1 can be removed from the pipe.

[0021] The plug body 1 is sleeved with a stabilizing sheath 5 at the end far from the mounting hole 3. After loosening the throat clamp 2, the stabilizing sheath 5 can be held to facilitate pulling or installing the plug body 1 from the pipeline.

[0022] The plug body 1 is embedded with a fixing disc 6 at the end far from the mounting hole 3. The fixing disc 6 is uniformly and integrally fixed with a plurality of support rods 7 on the circumferential side near the mounting hole 3. The vertical section of the support rod 7 is in the shape of "L". The support rod 7 is embedded into the clasp 4 at the inner side of the end far from the fixing disc 6. The plurality of support rods 7 are fixed on the fixing disc 6. Since the plug body 1 is flexible rubber, the plug body 1 will not be deformed under the support of the plurality of support rods 7 when the plug body 1 is stored.

[0023] The plug body 1 is uniformly and integrally provided with two driving rings 8 on the outer circumferential side of the end far from the stabilizing sheath 5. When the plug body 1 needs to be installed on the pipeline, the two driving rings 8 are pulled respectively to expand the opening of the mounting hole 3, facilitating the plug body 1 to be sleeved on the pipeline.

[0024] The inner circumferential side of the throat clamp 2 is uniformly and integrally provided with a plurality of fixing blocks 9. The fixing block 9 is in the shape of a hemisphere. The outer side wall of the fixing block 9 abuts against the outer circumferential side of the plug body 1. Under the action of the plurality of fixing blocks 9, the friction between the throat clamp 2 and the plug body 1 can be increased to prevent the throat clamp 2 from rotating when it is loosened.

[0025] The above is only the preferred embodiment of the present application, so equivalent changes or modifications made according to the structure, features and principles described in the patent application range of the present application are included in the patent application range of the present application.
