Description
Technical Field
[0001] The utility model relates to the technical field of pipeline plugging, in particular to a pipeline pressure plugging device. Background Art
[0002] During production and operation activities, pipes connected to production devices or equipment will have through-hole-shaped leaks, crack-shaped leaks and through-hole / crack-shaped leaks on their outer walls due to factors such as long-term exposure to the sun, long-term corrosion and long-term wear. This is especially true for some steam pipes, circulating water pipes and desalted water pipes. If the leaks on these pipes are not sealed in time, it will not only cause safety accidents or some safety hazards, but also cause waste of steam, circulating water or desalted water.
[0003] When plugging leaks on these pipelines, the air or liquid in the steam pipeline, circulating water pipeline or desalted water pipeline is first discharged by using the production device or production equipment, and then the production device or production equipment is shut down, and then the pipeline section with the leak is welded to complete the process of plugging the leak on the pipeline. Although this method can plug the leak on the pipeline, the production device or production equipment needs to be shut down during this process, which not only delays the production efficiency of the production device or production equipment, but also increases production costs.
[0004] Therefore, it is necessary to improve and design the sealing structure of the pipeline to solve the problem that when a leak occurs in the pipeline, the machine needs to be shut down to seal the leak. Utility Model Content
[0005] The utility model aims to provide a pipeline pressure plugging device to solve the problem that when a leak occurs in the pipeline, the machine needs to be stopped to plug the leak on the pipeline.
[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0007] A pipeline pressure plugging device comprises a first clamp half ring, a second clamp half ring, a connecting pipe, a sealing gasket and a gate valve; the first clamp half ring and the second clamp half ring are connected by a bolt assembly, a through hole 1 is opened in the middle of the outer wall of the first clamp half ring, one end of the through hole 1 is communicated with a connecting pipe connected to the outer wall of the first clamp half ring and with a gate valve, and the other end of the through hole 1 is communicated with a groove 1 opened on the inner wall of the first clamp half ring, and a sealing gasket matching the groove 1 and the through hole 1 is also adhered to the inner wall of the first clamp half ring.
[0008] Furthermore, the first clamp half ring has a first connection block with an internal threaded through hole 1 on both sides, and the second clamp half ring has a second connection block with an internal threaded through hole 2 on both sides. The internal threaded through hole 2 is threadedly connected to the internal threaded through hole 1 through a bolt assembly.
[0009] Furthermore, the sealing gasket is provided with a second groove, which is communicated with a first groove and a through hole respectively provided on the inner wall of the first clamp half ring.
[0010] Furthermore, one end of the connecting pipe away from the first clamp half ring is connected to the flange.
[0011] Furthermore, a straight slot-shaped glue injection groove 1 is provided on the inner wall of the first clamp half ring, and the sealing gasket is located between the glue injection groove 1. The glue injection groove 1 is connected to a glue guide channel 1 provided on the first clamp half ring, and a plug is threadedly connected to one end of the glue guide channel 1 close to the outer wall of the first clamp half ring.
[0012] Furthermore, a straight slot-shaped glue injection groove 2 is provided on the inner wall of the second clamp half ring, and the glue injection groove 2 is connected to a glue guide channel 2 provided on the second clamp half ring. A plug 2 is threadedly connected to one end of the glue guide channel 2 near the outer wall of the second clamp half ring.
[0013] Working process, see Figure 1 and Fig.12 When sealing a leak on a pipeline, first open the gate valve on the connecting pipeline, then sleeve the first clamp ring on the leak on the pipeline, and align the through hole 1 and the groove 1 on the first clamp ring with the leak on the pipeline, then sleeve the second clamp ring on the pipeline corresponding to the first clamp half ring, and then thread the first clamp half ring and the second clamp half ring together with a bolt assembly. During the threading process of the first clamp half ring and the second clamp half ring, the first clamp half ring and the second clamp half ring approach each other, so that the first clamp half ring and the second clamp half ring are tightly sleeved on the pipeline with the leak, and finally close the gate valve on the connecting pipeline to confine the gas or liquid emerging from the leak in the connecting pipeline to complete the process of sealing the leak on the pipeline.
[0014] In the above process, since a sealing gasket matching the groove 1 and the through hole 1 is adhered to the inner wall of the first clamp half ring, when gas or liquid leaks from the leak point of the pipeline to between the first clamp half and the outer wall of the pipeline, the gas or liquid will not leak out from between the first clamp half ring and the outer wall of the pipeline, thereby further improving the overall sealing of the pipeline pressure plugging device.
[0015] Compared with the prior art, the utility model has at least one of the following beneficial effects:
[0016] 1. The utility model integrates a pipeline pressure plugging device through a first clamp half ring, a second clamp half ring, a connecting pipe, a bolt assembly, a sealing gasket and a gate valve. When plugging a leak on a pipeline, the pipeline pressure plugging device can be installed at the leak on the pipeline to plug the leak on the pipeline without shutting down the device or equipment connected to the pipeline for processing, so as to solve the problem of shutting down to plug the leak on the pipeline when a leak occurs in the pipeline.
[0017] 2. The utility model provides a straight-slot-shaped glue injection groove 1 on the inner wall of the first clamp half ring, and the glue injection groove 1 is connected with a glue guide channel 1 provided on the first clamp half ring. After the first clamp half ring and the second clamp half ring are installed on the pipe with a leak through a bolt assembly, glue can be introduced into the glue guide channel 1, and the introduced glue flows into the glue injection groove 1 along the glue guide channel 1. Since the glue injection groove 1 on the first clamp half ring is in tight contact with the outer wall of the pipe with a leak, when the glue solidifies, the first clamp half ring is sealed with the pipe with the leak through the glue, thereby improving the sealing between the first clamp half ring and the pipe with the leak.
[0018] 3. The utility model provides a straight slot-shaped glue injection groove No. 2 on the inner wall of the second clamp half ring, and the glue injection groove No. 2 is connected with a glue guide channel No. 2 provided on the second clamp half ring. After the first clamp half ring and the second clamp half ring are installed on the pipe with a leak point through a bolt assembly, glue can be introduced into the glue guide channel No. 2, and the introduced glue flows into the glue injection groove No. 2 along the glue guide channel No. 2. Since the glue injection groove No. 2 on the second clamp half ring is in tight contact with the outer wall of the pipe with a leak point, when the glue solidifies, the first clamp half ring is sealed and connected to the pipe with the leak point through the glue, thereby improving the sealing between the second clamp half ring and the pipe with the leak point.

DETAILED DESCRIPTION
[0032] like Figure 1-12 In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. Example
[0033] See also Figure 1-3 The pipeline pressure plugging device comprises a first clamp half ring 1, a second clamp half ring 2, a connecting pipe 3, a sealing gasket 4 and a gate valve 5; the first clamp half ring 1 and the second clamp half ring 2 are connected by a bolt assembly 6, a through hole 7 is opened in the middle of the outer wall of the first clamp half ring 1, one end of the through hole 7 is interconnected with the connecting pipe 3 connected to the outer wall of the first clamp half ring 1 and with the gate valve 5, and the other end of the through hole 7 is interconnected with a groove 8 opened on the inner wall of the first clamp half ring 1, and a sealing gasket 4 matching the groove 8 and the through hole 7 is also adhered to the inner wall of the first clamp half ring 1.
[0034] Working process, see Figure 1 and Fig.12When sealing the leak on the pipeline, first open the gate valve 5 on the connecting pipeline 3, then sleeve the first clamp ring 1 on the leak on the pipeline, and align the through hole 7 and the groove 8 on the first clamp ring 1 with the leak on the pipeline, then sleeve the second clamp ring 2 on the pipeline corresponding to the first clamp half ring 1, and then use the bolt assembly 6 to thread the first clamp half ring 1 and the second clamp half ring 2. During the threading process of the first clamp half ring 1 and the second clamp half ring 2, the first clamp half ring 1 and the second clamp half ring 2 approach each other, so that the first clamp half ring 1 and the second clamp half ring 2 are tightly sleeved on the pipeline with the leak, and finally close the gate valve 5 on the connecting pipeline 3 to limit the gas or liquid emerging from the leak in the connecting pipeline 3 to complete the process of sealing the leak on the pipeline.
[0035] In the above process, since a sealing gasket 4 matching the groove 8 and the through hole 7 is also adhered to the inner wall of the first clamp half ring 1, when gas or liquid leaks from the leak point of the pipeline to between the first clamp half ring 1 and the outer wall of the pipeline, the gas or liquid will not leak out from between the first clamp half ring 1 and the outer wall of the pipeline, thereby further improving the overall sealing of the pipeline pressure plugging device.
[0036] It should be noted that when installing the first clamp half ring 1 on a pipe with a leak, in order to prevent the gas or liquid coming out of the leak from lifting the first clamp half ring 1 mounted on the pipe, the gate valve 5 on the connecting pipe 3 needs to be opened when installing the first clamp half ring 1.
[0037] See also Figure 3-5 In order to realize the connection between the first clamp half ring 1 and the second clamp half ring 2 through the bolt assembly, the first clamp half ring 1 also has a first connecting block 10 with an internal threaded through hole 1 9 on both sides, and the second clamp half ring 2 also has a second connecting block 12 with an internal threaded through hole 2 11 on both sides. The internal threaded through hole 2 11 is threadedly connected with the internal threaded through hole 1 9 through the bolt assembly 6.
[0038] It should be noted that the first internal threaded through hole 9 is formed in the first connection block 10, and the second internal threaded through hole 11 is formed in the second connection block 12. Both the second connection block 12 and the first connection block 10 are rectangular.
[0039] It should be noted that the bolt assembly 6 includes two nuts and a bolt, and nuts are threadedly connected at both ends of the bolt.
[0040] See also Figure 3 , Figure 6 , Figure 7 and Figure 8The structure of the sealing gasket 4 between the first clamp half ring 1 and the leaking pipe is a rectangular column or a semi-ring. In order to prevent the sealing gasket 4 from covering the through hole 17 and the groove 18, a groove 2 14 is provided on the sealing gasket 4. Specifically, the groove 2 14 is respectively communicated with the groove 18 provided on the inner wall of the first clamp half ring 1 and the through hole 17 provided on the first clamp half ring 1.
[0041] In actual use, after the first clamp half ring 1 and the second clamp half ring 2 are installed on the pipe with a leak point through the bolt assembly 2, the gas or liquid coming out of the leak point first passes through the sealing gasket 4, and then flows into the connecting pipe 3 along the groove 8 through the through hole 7. Since the sealing gasket 4 is provided with a groove 2 14, the groove 2 14 is respectively interconnected with the groove 8 opened on the inner wall of the first clamp half ring 2 and the through hole 7 opened on the first clamp half ring 1, and the gas or liquid flowing through will not be blocked by the sealing gasket 4.
[0042] See also Figure 4 In order to facilitate the assembly of the connecting pipe 3 with other pipes, the end of the connecting pipe 3 away from the first clamp half ring 1 is connected to the flange 15.
[0043] In actual use, when the connecting pipe 3 is assembled with other pipes, another flange is welded at one end of the other pipe, and then the two flanges are aligned, and then the flange is connected to another flange with several other bolt assemblies to complete the assembly process of the connecting pipe 3 with other pipes.
[0044] See also Figure 1 In order to prevent stress concentration at the edges of the first clamp half ring 1 and the second clamp half ring 2, the edges of the first clamp half ring 1 and the second clamp half ring 2 are both rounded (not shown in the figure).
[0045] In actual use, when the edges of the first clamp half ring 1 and the second clamp half ring 2 are hit, since the edges of the first clamp half ring 1 and the second clamp half ring 2 are rounded, the stress on the edges of the first clamp half ring 1 and the second clamp half ring 2 is relatively dispersed, and the first clamp half ring 1 and the second clamp half ring 2 are not easily damaged.
[0046] See also Figure 4 , Figure 6 , Figure 7 , Figure 8 and Fig.11 In order to improve the sealing between the first clamp half ring 1 and the outer wall of the pipe with a leak, a straight slot-shaped glue injection groove 16 is opened on the inner wall of the first clamp half ring 1. The glue injection groove 16 is connected to a glue guide channel 17 opened on the first clamp half ring 1. A plug is threadedly connected to one end of the glue guide channel 17 near the outer wall of the first clamp half ring 1.
[0047] In actual use, after the first clamp half ring 1 and the second clamp half ring 2 are installed on the pipe with a leak through the bolt assembly 6, unscrew the plug 1 that is threadedly connected to the glue guide channel 17, and introduce glue into the glue guide channel 17. The introduced glue flows into the glue injection groove 16 along the glue guide channel 17. Since the glue injection groove 16 on the first clamp half ring 1 is in close contact with the outer wall of the pipe with a leak, when the glue solidifies, the first clamp half ring 1 is sealed and connected to the pipe with a leak through the glue, thereby improving the sealing between the first clamp half ring 1 and the pipe with a leak.
[0048] It should be noted that in order to prevent the glue injection groove 16 on the inner wall of the first clamp half ring 1 from being covered by the sealing gasket 4 adhered to the inner wall of the first clamp half ring 1 , the sealing gasket 4 is arranged between the glue injection grooves 16 .
[0049] See also Figure 5 , Fig. 9 , Fig.10 and Fig.11 In order to improve the sealing between the second clamp half ring 2 and the outer wall of the pipe with a leak, a straight slot-shaped glue injection groove 18 is also opened on the inner wall of the second clamp half ring 2. The glue injection groove 18 is connected to a glue guide channel 19 opened on the second clamp half ring 2. The glue guide channel 19 is threadedly connected with a plug 2 at one end close to the outer wall of the second clamp half ring 2.
[0050] In actual use, after the first clamp half ring 1 and the second clamp half ring 2 are installed on the pipe with a leak through the bolt assembly 6, unscrew the plug 2 threadedly connected to the glue guide channel 19, and introduce glue into the glue guide channel 18. The introduced glue flows into the glue injection groove 18 along the glue guide channel 18. Since the glue injection groove 18 on the second clamp half ring 2 is in close contact with the outer wall of the pipe with a leak, when the glue solidifies, the first clamp half ring 1 is sealed and connected to the pipe with a leak through the glue, thereby improving the sealing between the second clamp half ring 1 and the pipe with a leak.
