Abstract
Description
Technical Field
[0001] The utility model relates to the field of clamp connection, in particular to a pipeline clamp with good sealing performance. Background Art
[0002] Clamp connection is also known as grooved connection. A groove is provided at the end of the pipeline to be connected, and then a sealing ring is covered on the groove. Such sealing rings are mostly made of flexible materials such as rubber. Then, two corresponding half-rings are combined into a complete ring to fix the sealing ring and thus connect the two pipelines. Currently, there are many types of pump truck elbow clamps on the market, and most of them are forged or cast. However, through observation, after the clamp is fixed for a long time, due to the gap at the connection of the ends of the two half-rings, substances such as water flow and dirt are likely to enter the inside of the clamp along the gap, thereby corroding the sealing ring at the end docking position. Over time, the sealing ring is damaged, resulting in a decrease in the sealing performance of the docking of the two pipelines. Therefore, it is necessary to solve the problem of the sealing ring body at the gap between the ends of the two half-rings of the clamp being eroded by water flow and dirt. Summary of the Utility Model
[0003] Aiming at the deficiencies in the prior art, the utility model provides a pipeline clamp with good sealing performance, which solves the problem of erosion of the sealing ring body at the gap between the ends of the two half-rings of the pipeline clamp in the prior art.
[0004] According to an embodiment of the utility model, a pipeline clamp with good sealing performance is characterized in that: it includes a base, two semi-circular fixed outer rings that can be combined into a circular ring, the outer wall surface of one of the fixed outer rings is fixedly connected to the base, and it also includes two semi-circular sealing inner rings that can be combined into a circular ring. The sealing inner rings are arranged inside the fixed outer rings, the outer wall surface of the sealing inner rings is fixedly connected to the inner wall surface of the fixed outer rings, the arc lengths of the outer wall of the sealing inner rings and the inner wall surface of the fixed outer rings are the same. One end of the sealing inner ring also protrudes a part along the circumference outside the fixed outer ring to form a protruding section, and the other end correspondingly contracts towards the inside of the fixed outer ring to form a contracting section. The protruding sections and contracting sections at the adjacent ends of the two sealing inner rings are mutually engaged. One end of the two fixed outer rings is hinged, and the other end is fixedly connected by bolts. A limiting member is also provided at the relative ends of the two fixed outer rings fixedly connected by bolts to prevent the bolts from coming out.
[0005] Furthermore, on the outer arc surface at one end of the two semi-circular fixed outer rings, there are alternately arranged hole seats and corresponding rotating shafts, and the rotating shafts are inserted into the two hole seats so that the two fixed outer rings can rotate.
[0006] Furthermore, two groups of relative fixing plates are respectively provided on the outer arc surface of the other end of the two semicircular fixed outer rings, and the bolt includes a nut and a screw rod. One end of the screw rod is rotatably connected between one group of relative fixing plates, and the other end is inserted between the other group of relative fixing plates and fixed by the nut.
[0007] Furthermore, the limiting member includes limiting protrusions arranged around the nut on both sides of the top of the fixing plate. When the nut is displaced to abut the top of the fixing plate, the limiting protrusions limit its displacement around the nut, and the rotation of the screw is also synchronously restricted, and cannot fall out from between the fixing plates.
[0008] Furthermore, the protruding section includes a matching block and an adjacent notch, the contracting section includes a matching block and an adjacent notch in opposite positions, the matching block and the corresponding notch are embedded in one end adjacent to the sealing inner ring, and the matching block and the notch are embedded in the notch.
[0009] Furthermore, the position range of the matching block and the notch on the sealing inner ring is such that the abutment at both ends of the fixed outer ring and the bottom of the corresponding protruding section are used as the zero scale line reference, and the angular range of the circumferential protruding length of the protruding section relative to the zero scale line is between 15 degrees and 45 degrees.
[0010] Furthermore, the inner wall of the sealing inner ring is recessed inwardly to form a groove, and the inner wall surface of the groove is provided with tooth-shaped protrusions.
[0011] Furthermore, mounting holes are provided on both sides of the base, and the mounting holes cooperate with corresponding bolts to mount the base on any plane adjacent to the pipeline.
[0012] The technical principle of the utility model is as follows: before connecting two pipes, first put a sealing ring on one of the pipes, then abut the ends of the two pipes, surround and cover the connection of the two pipes, then set two semicircular fixed outer rings hinged in advance around the sealing ring and close the two unfolded fixed outer rings, and at the same time, two sealing inner rings are embedded and surrounded on the outer surface of the sealing ring by using the protruding section and the contraction section, and then the other end of the fixed outer ring is fixedly connected by bolts, and the fixed outer ring and the sealing inner ring squeeze the sealing ring. At this time, the embedding position of the protruding section and the contraction section of the two sealing inner rings is staggered from the abutment of the two fixed outer rings, and the gap at the connection of the two ends of the two fixed outer rings has been blocked by the protruding section, so that water flow and dirt cannot directly enter the interior of the fixed outer ring from the gap to cause erosion of the sealing ring body.

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0024] like Figure 1 As shown, a pipe clamp with good sealing performance is characterized in that it includes a base 4, two semi-circular fixed outer rings 1 that can be combined into a circular ring, the outer wall surface of one of the fixed outer rings 1 is fixedly connected to the base, and also includes two semi-circular sealing inner rings 2 that can be combined into a circular ring, the sealing inner ring 2 is arranged inside the fixed outer ring 1, the outer wall surface of the sealing inner ring 2 is fixedly connected to the inner wall surface of the fixed outer ring 1, the outer wall of the sealing inner ring 2 is consistent with the inner wall surface of the fixed outer ring 1, and one end of the sealing inner ring 2 also protrudes along the circumferential direction A part of the fixed outer ring 1 is formed into a protruding section, and the other end is correspondingly contracted toward the inside of the fixed outer ring 1 to form a contracted section. The protruding section and the contracted section at the adjacent ends of the two sealing inner rings 2 are embedded with each other, and the position where the protruding section and the contracted section are embedded is staggered with the position where the fixed outer ring 1 abuts. External water or dirt entering the inside of the fixed outer ring 1 will be blocked by the protruding section. One end of the two fixed outer rings 1 is hinged, and the other end is fixed by a bolt 3. A limiting member is also provided at the opposite end of the two fixed outer rings 1 fixed by the bolt 3 to prevent the bolt 3 from falling out.
[0025] Further, such as Figure 2 and Figure 3As shown, the outer arc surfaces of the opposite ends of the two semicircular fixed outer rings 1 are provided with mutually staggered hole seats 11 and corresponding rotating shafts 12, and space is left between the hole seats 11 so that another hole seat 11 can be embedded, and then the rotating shaft 12 is inserted into the two hole seats 11 so that the two fixed outer rings 1 can be hinged and rotated at the same time.
[0026] Further, such as Figure 1 and Figure 2 as well as Figure 3 As shown, two groups of opposite fixing plates 13 are respectively provided on the outer arc surface of the other end of the two semicircular fixed outer rings 1 closed into a circular ring, and the bolt 3 includes a nut 33 and a screw rod 31. Two short shafts are fixedly connected to both sides of one end of the screw rod 31, so that one end of the screw rod 31 is a T-shaped end 32. The screw rod 31 is transferred between one group of opposite fixing plates 13 by using the T-shaped end 32, and the other end away from the T-shaped end 32 is inserted between the other group of opposite fixing plates 13. After the nut 33 is tightened with the help of the thread on the screw rod 31, the bottom of the nut 33 simultaneously presses against the edge of the fixing plate 13, thereby fixing the screw rod 31 between the two groups of fixing plates 13.
[0027] Further, such as Figure 1 and Figure 2 as well as Figure 3 As shown, the limiting member includes limiting protrusions 14 arranged around the nut 33 on both sides of the top of the fixing plate. When the nut 33 moves to abut the top of the fixing plate 13 when the screw rod 31 moves, the limiting protrusions 14 limit the displacement of the nut around the nut, and the rotation of the screw rod 31 is also synchronously limited, and cannot escape from between the fixing plates 13.
[0028] Further, such as Figure 1 and Figure 2 As shown, the protruding section includes a matching block 21 and an adjacent notch 22, and the contraction section includes a matching block 21 and an adjacent notch 22 in opposite positions. The matching block 21 and the corresponding notch 22 are embedded at one end adjacent to the sealing inner ring, and the embedded position of the two is staggered from the gap at the abutment of the fixed outer ring 1. The dirty water enters the gap between the two fixed outer rings 1 and then enters the embedded gap of the sealing inner ring 2, which will be blocked for the most part and cannot cause a significant impact on the sealing ring located in the inner layer.
[0029] Furthermore, the fitting position of the matching block 21 and the notch 22 on the sealing inner ring 2 is such that the abutment of the two ends of the fixed outer ring 1 and the bottom of the corresponding protruding section are used as the zero scale line reference, and the angular range of the protruding length of the protruding section along the circumferential direction relative to the zero scale line is between 15 degrees and 45 degrees. Figure 2As shown, the included angle between the fitting part and the end of the fixed outer ring 1 is 20 degrees. On the one hand, this angle can completely block the gap between the fixed outer rings 1, and on the other hand, it will not hinder the initial installation of the fixed outer ring 1 and the sealing inner ring 2 onto the pipeline body.
[0030] Furthermore, as Figure 4 and Figure 5 shown, the inner wall of the sealing inner ring 2 is also recessed inwardly to form a groove 23. The width of the groove 23 is generally greater than or equal to the width of the sealing ring body covering the pipeline port. The sealing ring body is embedded in the groove 23, and thus the sealing inner ring 2 can completely cover the sealing inner ring body. The inner wall surface of the groove 23 is provided with tooth-shaped protrusions 24 to provide friction for gripping the outer surface of the sealing ring body embedded in the groove 23, so that the entire embodiment forms a more powerful connection support for the pipeline docking part.
[0031] Furthermore, as Figure 1 and Figure 2 shown, mounting holes 41 are also provided on both sides of the base 4. The mounting holes 41 can cooperate with corresponding bolts to mount the base 4 on any plane 5 adjacent to the pipeline.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
