[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: According to Figure 1 and Figure 2 The fixture shown is used for injecting glue to plug leaks in pipe elbows, including a fixture body 3; the fixture body 3 includes several body modules with the same structure; a connecting mechanism for connecting the body module to the pipe elbow 1 to be plugged is fixedly connected to the fixture body 3; a glue injection hole 2 for glue injection is opened on the fixture body 3; there is a gap between the inner wall of the body module and the outer wall of the pipe elbow 1 to be plugged, forming a glue injection cavity 6.

[0025] In actual use, when a leakage problem occurs in the pipe elbow, the clamp body 3 is connected to the pipe elbow to be plugged through the connecting mechanism. Then, the glue injection gun head is inserted into the glue injection hole 2, and the sealing glue stick is pressed into the glue injection cavity 6 formed by the gap between the pipe elbow and the clamp body 3 to inject glue under pressure until it is completely sealed and the leakage stops, that is, the leak is successfully plugged.

[0026] The utility model can quickly and smoothly complete the plugging operation of the fuel pipeline elbow leakage, which not only saves time and effort, but also does not require hot work, ensuring the safe and stable operation of the production equipment and a high success rate of leak plugging.

[0027] Example 2: According to Figure 1 and Figure 2 The illustrated fixture is used for injecting glue to seal leaks in pipe elbows. The difference from the first embodiment is that a glue injection valve is connected to the glue injection hole 2 .

[0028] In actual use, after the clamp body 3 is connected to the elbow of the pipe to be plugged through the connecting mechanism, the glue injection valve is installed on the glue injection hole 2, the glue injection valve is opened and the glue injection gun is connected, and the sealing glue stick is pressed in to start pressure injection until the leakage is completely blocked and stopped.

[0029] The glue injection hole 2 is connected to a glue injection valve, which can better control the glue injection process and ensure that the medium leaked outside the pipeline before glue injection will not spread.

[0030] Example 3: According to Figure 1 and Figure 2The fixture shown is used for glue injection and plugging leaks in pipe elbows. It differs from Example 1 in that: the fixture body 3 includes two body modules with the same structure; after the two body modules are connected relative to each other, an inner cavity matching the shape of the pipe elbow to be plugged is formed inside; a connecting mechanism is connected to the side edge of the body module, and the bolt assembly 5 connects the two body modules to the pipe elbow to be plugged through the connecting mechanism.

[0031] Furthermore, the distance between the inner wall of the body module and the outer wall of the pipe elbow 1 to be plugged is 10 mm to 30 mm.

[0032] In actual use, the two main modules are connected relative to each other on the pipe elbow to be plugged, and the two main modules are connected together through the connecting mechanism, making the preliminary preparation work for plugging the leak more convenient. Then, glue is injected into the glue injection cavity 6 through the glue injection hole 2 to seal. The glue evenly covers the outside of the pipe elbow 1 with a leak, achieving the effect of plugging the leak.

[0033] Example 4: According to Figure 1 and Figure 2 The illustrated fixture for sealing leaks in pipe elbows with glue injection differs from the third embodiment in that sealing mechanisms are provided on the inner sides of the two ends of the body module and at the contact points between the two body modules.

[0034] In specific applications, the setting of the sealing mechanism enables the clamp to be clamped more tightly on the outer wall of the straight pipe on both sides of the bending point of the pipe elbow to be plugged, so that a closed space is formed between the plugging tool and the pipe elbow to be plugged, thereby preventing the glue from leaking from both ends of the plugging clamp during glue injection, affecting the plugging effect.

[0035] Example 5: According to Figure 1 The fixture shown is used for glue injection and sealing leaks in pipe elbows. The difference from Example 1 or Example 3 is that the connecting mechanism includes a fixing ear 4 and a bolt assembly 5; the fixing ear 4 is fixedly connected to the fixture body 3, and the bolt assembly 5 is connected to the fixing ear 4.

[0036] In actual use, the function of the connecting mechanism is to stably connect the two main modules at the elbow of the pipe to be plugged, so as to facilitate the smooth implementation of subsequent glue injection and plugging work.

[0037] Furthermore, the fixing ear 4 is a square protrusion, and a connecting through hole for the bolt assembly 5 to pass through is opened at the center position of the fixing ear 4.

[0038] In specific applications, when the two main body modules are relatively buckled together at the elbow of the pipe to be plugged, the connecting holes of the fixing ears 4 on the two main body modules are aligned, and the bolt assembly 5 is inserted into the aligned connecting holes. The two main body modules are fixedly connected as one, which is simple and convenient.

[0039] Example 5: According to Figure 1 The fixture shown is used for injecting glue to seal leaks in pipe elbows. The difference from the third embodiment is that two glue injection holes 2 are provided on each main body module; the two glue injection holes 2 are respectively opened at corresponding positions on the pipes on both sides of the bending point of the pipe elbow to be sealed.

[0040] In actual use, the above technical solution is adopted to set the glue injection hole 2, so that the gap between the leak-proof fixture and the elbow of the pipe to be plugged is evenly injected with glue, ensuring the leak-proof effect.

[0041] In specific applications, the location of the glue injection hole 2 can also be set according to actual conditions.
