Description

Technical Field

[0001] This utility model relates to a quick pipe connection device, and more specifically to a half-section of a split joint and a split joint. Background Technology

[0002] Currently, in the event of a pipeline rupture or leak (such as a water pipe, oil pipe, or gas pipe), in order to restore pipeline flow in a timely manner, such as... Figure 1 The widely used method is the use of a half-joint 1a connection. During emergency repairs, two semi-tubular half-joints 11a are used to cover the damaged part A of the pipe within the cavity formed by the half-joint 1a. Then, fasteners (such as matching bolts and nuts) are used to tighten the semi-circular joint surface of the half-joint 1a, and the rubber sealing ring 3a is closed to seal the damaged point A of the pipe. In this way, the above method has the advantages of fast installation speed, saving time and effort, and simple and convenient installation.

[0003] However, when water flows from one end of the pipe to the other, the high water pressure inside the pipe will still cause the water flow to impact the split joint 1a, which can easily cause the rubber sealing ring 3a to twist or flip on both sides, thus affecting the sealing performance of the split joint 1a and consequently affecting the sealing of the pipe's break point A.

[0004] In view of this, this application has conducted in-depth research on this basis, resulting in this case. Utility Model Content

[0005] The purpose of this utility model is to provide a half-section of a sealing component that is not easily flipped and has good sealing performance, as well as a half-section of the sealing component.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] A split-joint half-body includes a half-body and a sealing half-body mounted on the half-body. The two ends of the sealing half-body are respectively sealed to the two ends of the half-body. The side where the half-body and the sealing half-body cooperate with each other is the inner side, and the other side is the outer side. The two long sides of the inner sidewall of the half-body are respectively provided with straight edge segments arranged along the length direction. The inner sidewall of the sealing half-body is respectively provided with straight edge grooves corresponding to the two straight edge segments. The straight edge segments of the corresponding long side of the half-body are tightly installed in the straight edge grooves corresponding to the two long sides of the sealing half-body.

[0008] Each of the straight edge segments extends to the corresponding end on the corresponding half-body.

[0009] A limiting step is provided on the rear side of each long side of the inner wall of the half-body, and an auxiliary straight edge section is provided on the front side of each long side of the inner wall of the half-body. The straight edge section in each long side of the inner wall of the half-body is located between the limiting step and the auxiliary straight edge section, and forms two sealing receiving grooves. Receiving portions are formed on each long side of the inner wall of the sealing half-body corresponding to the two sides of the straight edge grooves, and each sealing receiving groove is tightly fitted with each receiving portion one-to-one.

[0010] Both ends of each straight edge segment extend to the corresponding end of the corresponding half-body, both ends of each auxiliary straight edge segment extend to the corresponding end of the corresponding half-body, and both ends of each limiting step smoothly transition to the corresponding end of the corresponding half-body.

[0011] It also includes at least one connector, wherein when there is one connector, the connector is located in the middle between the two long sides of the sealing half; when there are two or more connectors, each connector is arranged sequentially at intervals along the length direction of the sealing half.

[0012] When the sealing half and the half body are assembled, the connector is embedded in the half body, or the inner sidewall of the connector is attached to the inner sidewall of the half body, or the connector is close to the inner sidewall of the half body.

[0013] The inner wall of the semi-body has a mounting groove arranged circumferentially, the connector is embedded in the mounting groove, and the inner wall of the connector is flush with the inner wall of the semi-body.

[0014] The connector is an arc-shaped strip, or the connector matches the inner sidewall of the semi-body.

[0015] A type of split joint includes two half-body sections and two sealing half-sections respectively mounted on the half-body sections. The two half-body sections are joined together to form a split-type pipe joint, and the two sealing half-sections cooperate to form a channel for sealing the pipe.

[0016] The sealing half-body corresponding to each of the two half-bodies is separately disposed, and each half-bodies and the sealing half-body are embedded in each other; or, the sealing half-body corresponding to each of the two half-bodies is integrally disposed, and each sealing half-body is integrally formed in the half-bodies.

[0017] One of the half-body bodies has a pressure relief hole, and a plug is installed on the pressure relief hole in a detachable manner.

[0018] The connector on the half-body having the pressure relief hole includes an integrally connected connecting portion arranged along the outer contour of the pressure relief hole and arc-shaped portions extending along the long side of the sealing half-body.

[0019] After adopting the above-mentioned half-body, the present invention has the following beneficial effects: 1. The present invention adopts a half-body with a straight edge section and a sealing half-body with a straight edge groove. When the half-body and the sealing half-body are assembled together, the straight edge section on the half-body is tightly inserted into the straight edge groove. At this time, the parts of the sealing half-body corresponding to the two sides of the straight edge groove are tightly attached to the two sides of the straight edge section of the half-body, so that the half-body can tightly install the sealing half-body through its straight edge section, so as to avoid the sealing half-body from loosening, shaking or flipping under the action of external force and affecting subsequent use, while ensuring the sealing performance after assembly.

[0020] 2. This utility model employs a straight edge section and an auxiliary straight edge section on each long side of the semi-body. When the sealing half-body is assembled onto the semi-body, the straight edge groove of the sealing half-body is tightly inserted into the corresponding straight edge section on the semi-body. At this time, each receiving part on the sealing half-body is tightly inserted into the corresponding sealing receiving groove on the semi-body, and each mutually assembled receiving part and sealing receiving groove are tightly fitted together, thereby tightly installing the sealing half-body. At the same time, since each straight edge section is located on both sides of the long side of the sealing half-body during the assembly of the semi-body and the sealing half-body, it can press the sealing half-body tightly, further ensuring that the sealing half-body will not flip or loosen during subsequent use.

[0021] 3. The present invention employs a connecting component, which can block the impact of water flow when further external force is applied to the sealing component half during water flow impact, thereby preventing the sealing component half from flipping or twisting and ensuring the sealing performance of the present invention.

[0022] 4. In this utility model, the connector is embedded in the mounting groove of the half-body, and the inner wall of the connector is flush with the inner wall of the half-body, thereby reducing the impact of water flow on the connector, that is, the water flow impacts the inner wall of the connector, ensuring the service life of the connector.

[0023] 5. This utility model adopts the setting of limiting steps. When the sealing half is installed on the half body, due to the limiting effect of the limiting steps on the sealing half, combined with the straight edge section, it can prevent water flow from directly impacting the sealing half and causing damage and aging during use.

[0024] After adopting the above-mentioned type of half-joint, the present invention has the following beneficial effects: 1. When the two half-joint halves are assembled together to form a half-joint, the connecting parts on the two sealing halves are respectively located on the inner sidewall of the corresponding half-body. In this way, when the half-joint is in use, that is, when the two halves surround each other and enclose the damaged part of the pipe, the two sealing halves seal each other to seal the damaged part of the pipe. Due to the setting of the straight edge section on the two halves, the sealing half is tightly set on the corresponding straight edge section. The straight edge section plays a role in fixing and supporting, and the two sealing halves fit tightly together to press the two sealing halves tightly, ensuring that the sealing halves are not easily twisted due to loosening or shaking, especially under the impact of water flow.

[0025] 2. When the two halves of the main body enclose the damaged part of the pipe, and the two sealing halves seal the damaged part of the pipe, the auxiliary straight edge sections on the two halves can block some of the water pressure when the water pressure is high, thus dispersing the impact of the water flow and preventing the water flow from directly impacting the sealing halves. At the same time, the straight edge sections and the limiting steps ensure that the sealing halves are tightly sealed on the halves, and the two sealing halves fit tightly together to press the two sealing halves together, ensuring that the sealing halves are not prone to twisting due to loosening or shaking. Furthermore, combined with the connecting parts, an outward force is applied to the sealing halves when the water flow impacts, thereby blocking the impact of the water flow and preventing the sealing halves from flipping or twisting, thus ensuring the sealing performance of this utility model.

[0026] 3. The design incorporates a pressure relief hole on one half of the main body. Since pressure is relieved through the pressure relief hole, it is convenient and simple to assemble this utility model to the damaged part of the pipeline. After installation, the pressure relief hole can be sealed with a plug. Furthermore, when disassembling this utility model, the pressure can be relieved by opening the pressure relief hole, making disassembly of this utility model convenient. Attached Figure Description

[0044] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0045] Example 1

[0046] This invention provides a half-section of a split element, which is an improvement on the conventional half-section of a split element.

[0047] like Figure 2 As shown - Figure 5As shown, the half-body 100 includes a half-body 1 and a sealing half-body 2. The sealing half-body 2 is installed on the half-body 1. In this embodiment, the material of the sealing half-body 2 can be the same as that used in the sealing half-body in existing half-body joints. Preferably, the sealing half-body 2 is a rubber seal.

[0048] For ease of description, the side where the half-body 1 and the sealing half-body 2 cooperate is called the inner side, and the other side is called the outer side. The side of the half-body 1 closer to the middle position is called the front side, and the side farther from the middle position is called the rear side.

[0049] The inner sidewall of the aforementioned half-body 1 is provided with straight edge segments 11 on its two long sides, that is, each half-body 1 has two straight edge segments 11, both of which are arranged along the length direction. Here, the long side of the half-body 1 refers to the corresponding side of the half-body 11 arranged along its axial direction, which refers to the axial direction when the two half-body 1s are enclosed together. The inner sidewall of the sealing half-body 2 is provided with straight edge grooves 21 corresponding to the two straight edge segments 11 of the half-body 1. The two straight edge segments 11 and the two straight edge grooves 21 are tightly inserted and fitted one-to-one, and the two ends of the half-body 1 and the two ends of the sealing half-body 2 are respectively... The sealing half 2 is installed in a one-to-one manner so that the two ends of the sealing half 2 are respectively installed at the two ends of the half body 1, that is, the sealing half 2 is completely installed on the inner side wall of the half body 1. The two long sides of the sealing half 2 are connected by a connector 3. In other words, the first end of the connector 3 is integrally connected to the front side of one of the long sides of the sealing half 2, and the second end of the connector 3 is integrally connected to the front side of the other long side of the sealing half 2. Here, the long side of the sealing half 2 refers to the side corresponding to the long side of the half body 1.

[0050] To elaborate further, such as Figure 2 As shown - Figure 3 As shown, the aforementioned connector 3 can be embedded, closely attached to, or adjacent to the inner wall of the cavity of the semi-body 1. Specifically, both ends of the connector 3 extend circumferentially along the inner wall of the cavity of the semi-body 1. The connector 3 can be a structure that matches the cavity of the semi-body 1. Preferably, the connector 3 is an arc-shaped strip. Here, the cavity refers to the inner part of the semi-body 1 corresponding to the portion where the two ends and the two long sides surround each other. Thus, as... Figure 3 As shown, when the sealing half 2 is installed inside the half body 1, the inner wall of the connector 3 can be tightly attached to the inner wall of the cavity of the half body 1, and at this time the connector 3 is adapted to the cavity of the half body 1.

[0051] Furthermore, when the sealing half 2 is installed inside the half body 1, the inner wall of the connector 3 can also be adjacent to the inner wall of the chamber of the split joint 1; preferably, as Figure 2As shown, in this embodiment, when the sealing half 2 is installed inside the half body 1, the connector 3 is embedded in the inner wall of the cavity of the half body 1. That is, the cavity has a circumferentially arranged mounting groove 30. The mounting groove 30 is located in the middle of the cavity, and both ends of the mounting groove 30 extend to the corresponding long side. The size and shape of the mounting groove 30 are adapted to the size and shape of the connector 3. When the connector 3 is installed in the mounting groove 30, the outer wall of the connector 3 is flush with the inner wall of the cavity, thereby reducing the impact of water flow on the connector 3. That is, it avoids the impact of water flow on the side of the connector 3 near the port of the half body 1, ensuring the sealing performance of the sealing half 2, and also ensuring the service life of the connector 3 (i.e., the sealing half 2).

[0052] As a preferred embodiment, the front sidewall of the long side of the half-body 1 is provided with a clearance opening corresponding to the position of the connector 3, so as to facilitate the assembly of the sealing half-body 2 onto the half-body 1, while preventing the connector 3 from protruding from the half-body 1.

[0053] Furthermore, the aforementioned connector 3 can be provided in at least two forms, and is not limited to a single connector 3. When there are at least two connectors 3, each connector 3 is arranged sequentially at intervals along the length direction (i.e., axial direction) of the half-body 1. Preferably, each connector 3 is arranged at uniform intervals and is embedded in the cavity of the half-body 1 in the manner described above. In this embodiment, the number of connectors 3 is set according to the actual situation and is not limited to what is described above.

[0054] like Figure 4 As shown - Figure 5 As shown, in the above-mentioned semi-body 1, the structure of each long side of its inner wall is the same. Therefore, the description is based on one of the long sides. The straight edge segment 11 on the long side protrudes from the inner wall of the long side so that the straight edge segment 11 can block part of the water pressure when the water pressure is high.

[0055] Furthermore, in this embodiment, the long side of the semi-body 1 is divided into two platform surfaces 12 by the straight edge segment 11 thereon. Correspondingly, the long side of the inner wall of the sealing half 2 forms two receiving surfaces 22 by the straight edge groove 21 thereon. Moreover, the platform surface 12 on the front side matches the receiving surface 22 on the front side, and the platform surface 12 on the rear side matches the receiving surface 22 on the rear side. In this way, when the sealing half 2 is installed in the semi-body 1, that is, after the straight edge groove 21 of the sealing half 2 and the straight edge segment 11 of the semi-body 1 are tightly inserted into each other, the sealing half 2 is tightly clamped on the straight edge segment 11, thereby ensuring that the sealing half 2 is tightly sealed on the semi-body 1, so as to avoid the sealing half 2 from loosening, shaking or flipping due to water pressure during subsequent use. Wherein, after the straight edge groove 21 of the sealing half 2 and the straight edge section 11 of the half body 1 are tightly inserted into each other, the front side of the long side of the sealing half 2 smoothly transitions with the inner wall of the cavity of the half body 1, or a step is formed between the front side of the long side of the sealing half 2 and the inner wall of the cavity of the half body 1.

[0056] Furthermore, the inner wall of the aforementioned half-body 1 has arc-shaped grooves 13 at both ends, and the inner wall of the sealing half-body 2 has arc-shaped segments 23 corresponding to the arc-shaped grooves 13 on the half-body 1. The two arc-shaped grooves 13 and the two arc-shaped segments 23 are respectively engaged in a one-to-one snap-fit. The four platform surfaces 12 on the half-body 1 are respectively connected to the two arc-shaped grooves 13 to facilitate the sealing assembly of the sealing half-body 2 onto the half-body 1. Preferably, the first end of each straight edge segment 11 of the half-body 1 extends to one end adjacent to the corresponding arc-shaped groove 13, and the second end extends to the other end adjacent to the other arc-shaped groove 13, thereby ensuring the sealing performance of the half-body 1 around its perimeter when the sealing half-body 2 is assembled onto the inner wall of the half-body 1. It should be noted that the two ends of the half-body 1 and the two ends of the sealing half-body 2 are respectively installed one-to-one. The installation structure can also adopt other existing conventional installation structures, that is, the installation structures already used on conventional split joints, which will not be described in detail here.

[0057] This embodiment describes a split-type half-body, which features straight edge segments on the half-body and straight edge grooves on the sealing half-body. After the half-body and sealing half-body are assembled, each straight edge segment is sandwiched between the two sides of the corresponding straight edge groove on the sealing half-body, and the two side walls of the straight edge groove are tightly fitted to the straight edge segment. This ensures that the long side of the sealing half-body is tightly pressed against the half-body, preventing the sealing half-body from loosening or shaking during subsequent use, and thus preventing the sealing half-body from flipping or twisting. The two ends of the sealing half-body are installed on the half-body in a conventional manner, thereby achieving a sealed fit around the half-body, ensuring the sealing performance of this invention. Furthermore, the connecting parts prevent the sealing half-body from twisting or flipping during water flow impact.

[0058] Example 2

[0059] like Figure 6 As shown - Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that a limiting step 51 and an auxiliary straight edge section 52 are respectively provided on each long side of the inner wall of the half-body 1 corresponding to both sides of the straight edge section, and the long side of the inner wall of the sealing half-body 2 is adjusted accordingly.

[0060] Specifically, a limiting step 51 is provided on the rear side of each long side of the inner wall of the half-body 1, that is, the long side of the half-body 1 is formed by the limiting step 51 so that the rear side wall of the corresponding side of the sealing half-body 2 abuts against the limiting surface; and, an auxiliary straight edge segment 52 is provided on the front side of each long side of the inner wall of the half-body 1. Preferably, the auxiliary straight edge segment 52 is integrally connected to the front side of the long side and protrudes from the inner wall of the half-body 1; wherein, in each long side of the inner wall of the half-body 1, the straight edge segment 11 is located between the limiting surface of the limiting step 51 and the auxiliary straight edge segment 52, preferably located between the two. The middle position, and the inner sidewall of the half-body 1 corresponds to the space between the limiting step 51 and the auxiliary straight edge section 52, and two sealing receiving grooves 53 are formed through the straight edge section 11; each long side of the inner sidewall of the sealing half-body 2 forms two receiving parts 61 through the straight edge groove 21, and each sealing receiving groove 53 and each receiving part 61 are tightly fitted one-to-one, that is, the two sealing receiving grooves 53 on each long side of the half-body 1 and the two receiving grooves 53 on the corresponding long side of the sealing half-body 2 are tightly inserted and fitted one-to-one, so that each long side of the sealing half-body 2 is tightly attached to and clamps the corresponding straight edge section 11.

[0061] Furthermore, the two ends of each auxiliary straight edge segment 52 extend to the corresponding ends adjacent to the half-body 1, and the two ends of each limiting step 51 smoothly transition to the corresponding ends on the half-body 1, thereby ensuring that the sealing half-body 2 completely seals the half-body 1.

[0062] This embodiment describes a split-joint half-body, which employs a limiting step 51, an auxiliary straight edge section 52, and a straight edge section 11 on the long side of the half-body 1. This allows the long side of the sealing half-body 2 to be tightly installed when it is assembled onto the half-body 1. Specifically, the two sides of the sealing half-body 2 corresponding to the straight edge groove are tightly fitted onto the straight edge section 11, and the straight edge section 11 is clamped. This ensures that the sealing half-body 2 is firmly pressed onto the half-body 1, thereby further ensuring the sealing performance of the sealing half-body 2 and preventing it from loosening during subsequent use.

[0063] Example 3

[0064] like Figure 4 As shown - Figure 5 As shown and as Figure 9As shown, this embodiment provides a half-joint, which includes two half-joint halves 100, both of which adopt the half-joint halves 100 as described in Embodiment 1 or Embodiment 2.

[0065] Specifically, sealing half-body 2 is installed on each of the two halves of the body 1. The two halves of the body 1 enclose each other to form a half-type pipe section. The half-type pipe section has two interconnected ports. The two sealing half-body 2 are located inside the half-type pipe section. The two sealing half-body 2 are gradually pressed together by the two halves of the body 1 to form a channel for the pipe to pass through and to seal the pipe.

[0066] In this embodiment, the materials of both sealing half-body 2 can be the same as those used in the sealing half-body of the existing half-joint. Preferably, both sealing half-body 2 are rubber seals.

[0067] It should be noted that when the two halves of the body 1 are fitted together, the installation structure between the two halves of the body 1 is the same as the installation structure between the two halves in a conventional split joint. For example, bolts and nuts are used to tightly close and fix the two halves together. In addition, other conventional installation structures can also be used, which will not be described in detail here.

[0068] As a preferred embodiment, in one of the two half-body 100s, a pressure relief hole 71 is provided in the middle position of one half-body 1. A plug is detachably installed on the pressure relief hole 71 in a conventional manner. In this way, during assembly, the pressure relief hole 71 facilitates the installation of the half-body at the damaged part of the pipeline; during installation, the pressure relief hole 71 facilitates the installation of the half-body. Preferably, the shape of the connecting member 3 can be adjusted accordingly. Specifically, the connecting member 3 includes an integrally connected connecting portion 31 and two arc-shaped portions 32. The front sidewalls of the two long sides of the sealing half 2 extend inward to form arc-shaped portions 32. The two arc-shaped portions 32 are matched with the inner sidewalls of the chamber of the half body 1. That is, one end of the two arc-shaped portions 32 is integrally connected to the front sidewall of the corresponding long side of the sealing half 2, and the other end of the two arc-shaped portions 32 is integrally connected to the connecting portion 31. The two arc-shaped portions 23 are arranged opposite to each other. The shape of the connecting portion 31 is the same as the outer contour of the pressure relief hole 7. The connecting portion 31 is arranged around the pressure relief hole 7, thereby ensuring the stabilizing effect of the connecting member 3 on the two long sides of the sealing half 2 without affecting the pressure relief hole 71.

[0069] Furthermore, in this embodiment, the half-body 1 and the sealing half-body 2 can be set separately or as one piece. When the half-body 1 and the sealing half-body 2 are set separately, the half-body 1 is cast integrally, and the sealing half-body 2 is formed integrally. Then, the two are fitted together using the structure described above. When the half-body 1 and the sealing half-body 2 are set integrally, the half-body 1 is cast integrally, and the rubber material forming the sealing half-body 2 is placed in the half-body 1 so that the sealing half-body 2 is directly formed in the half-body 1. That is, the half-body 1 is first cast integrally, and then the half-body 1 is placed in the cavity of the corresponding mold (the cavity with the aforementioned structure), and then the rubber material is poured in, so that the sealing half-body 2 is directly formed on the half-body 1. The molding of the half-body is selected according to the actual situation and is not limited here.

[0070] Furthermore, in the aforementioned half-body section, the assembly between the two halves of the body 1 adopts the conventional assembly structure in existing half-body sections. For example, each long side of the two halves of the body 1 is integrally connected with several mounting parts. The mounting parts on each long side of the half-body 1 are arranged sequentially at intervals along the length direction. In this embodiment, the number of mounting parts on each long side is set according to the actual situation and is not limited here. In this embodiment, the structure of each mounting part is the same, that is, the mounting part is provided with mounting holes. Each mounting part on the two halves of the body 1 corresponds to each other one-to-one. Each corresponding mounting part is equipped with a fastener, which can be a bolt and nut with mutual thread engagement.

[0071] Furthermore, in this embodiment, the side of the two sealing half-body 2 that cooperates with each other is the outer side of the sealing half-body 2, and the two sealing half-body 2 have the same structure. Therefore, we will take one of the sealing half-body 2 as an example for explanation. The two ends of the outer side wall of the sealing half-body 2 are respectively provided with sealing arc-shaped segments 24. Preferably, the two sealing arc-shaped segments 24 are respectively set as conventional toothed sealing segments. Preferably, there are multiple toothed sealing segments, and each toothed sealing segment is arranged sequentially along the axial direction to further improve the sealing performance.

[0072] In this design, the outer wall of the sealing half 2 is integrally connected with a first sealing protrusion 41 at the position corresponding to the first end of the two sealing arc segments 24. The two first sealing protrusions 41 are respectively connected to the corresponding ends of the sealing arc segments 24. The outer wall of the sealing half 2 is integrally connected with a second sealing protrusion 42 at the position corresponding to the second end of the two sealing arc segments 24. The two second sealing protrusions 42 are respectively connected to the corresponding ends of the sealing arc segments 24. In this way, when the two sealing half 2 are pressed together, the two first sealing protrusions 41 on one sealing half 2 are respectively fitted one-to-one with the two first sealing protrusions 41 on the other sealing half 2, and are pressed together in the state of gradual closing of the two half bodies 1. Similarly, the two second sealing protrusions 42 on one sealing half 2 are respectively fitted one-to-one with the two second sealing protrusions 42 on the other sealing half 2, and are pressed together in the state of gradual closing of the two half bodies 1. This achieves the sealing assembly of the two sealing half 2, thereby ensuring the internal sealing performance of the split joint.

[0073] Furthermore, in the aforementioned sealing half 2, the structures of the two first sealing protrusions 41 and the two second sealing protrusions 42 can both adopt the sealing protrusions used in the sealing half of the conventional half joint. For example, the structures of the two first sealing protrusions 41 and the two second sealing protrusions 42 are the same. Therefore, we will take one of the first sealing protrusions 41 as an example for explanation. The outer surface of the first sealing protrusion 41 is an inclined surface 411. The inclined surface 411 is arranged inclined from front to back along the inner side of the sealing half, and the outer surface of the first sealing protrusion 41 is connected to the end face of the adjacent sealing arc segment 24.

[0074] In this way, the sealing half 2 has protruding sealing protrusions. Two corresponding sealing protrusions are pressed together and adhered to each other. When the two sealing half 2 are closed and pressed tightly together, they can be completely pressed together, so that water cannot leak from between the two corresponding sealing protrusions, thus ensuring the sealing performance of the two sealing half 2. At the same time, due to the inclined surface 411 of each sealing protrusion, the two sealing half 2 can be progressively compressed when the two half bodies 1 are assembled together, ensuring that the force between the two sealing half 2 is uniform, and ensuring the sealing performance of the channel formed by the two sealing half 2. In addition, friction can be reduced when the two sealing half 2 are assembled, ensuring the service life of the sealing half 2.

[0075] This utility model discloses a type of split joint, the specific installation process of which is as follows: After the two sealing half-body 2 are respectively installed on the inner side wall of the corresponding half-body 1, the two half-body 1 are closed together to place the pipe inside. Then, the mounting holes on the rear side of the two half-body 1 are aligned one by one, and bolts are inserted into each corresponding mounting hole. The bolts are equipped with nuts. By screwing the nuts into the bolts, the two half-body 1 are gradually closed tightly, and then the outer side walls of the two sealing half-body 2 are gradually squeezed and pressed together until the outer side walls of the two sealing half-body 2 are completely pressed together, so that the two sealing half-body 2 seal the pipe in the channel, that is, the pipe damage point A is sealed in the split joint. The installation operation is simple, convenient and quick.

[0076] The above description is only a preferred embodiment of this invention. All equivalent changes and modifications made within the scope of the claims of this utility model shall fall within the scope of the claims of this utility model.
