Description

Technical Field

[0001] This utility model relates to the field of chemical pipeline maintenance, and in particular to an emergency sealing tool for chemical pipeline leaks. Background Technology

[0002] Chemical pipelines, as commonly used transportation equipment in the chemical industry, play an indispensable role in the chemical production and transportation process. Over long-term use, pipelines are prone to leakage due to various factors. Currently, common methods for sealing chemical pipeline leaks include using clamps and injecting adhesive for sealing, or using leak-sealing tape or steel strips for tightening and sealing. However, in actual use, the following problems still exist:

[0003] Traditional clamp-based glue injection technology has a complex structure, requires customization, and has a slow response speed. In the early stages of leakage, it is difficult to seal the leak point, resulting in a large amount of chemical leakage. The subsequent handling of the leak requires a lot of cost.

[0004] Methods such as sealing tape and binding tape mainly rely on physical compression of the leak point. For continuous or high-pressure leak points, the sealing reliability is insufficient, and they are prone to failure under continuous pressure and chemical corrosion.

[0005] Therefore, an emergency sealing tool for chemical pipeline leaks is proposed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as slow response speed in sealing leak points and easy failure of physical compression of leak points, and to propose an emergency sealing tool for chemical pipeline leaks.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An emergency sealing tool for chemical pipeline leaks includes a rubber pad, which is arc-shaped and has a sealing groove on its inner arc surface;

[0009] A fixing mechanism is provided at both ends of the rubber pad to fix the rubber pad to the chemical pipeline;

[0010] An injection tube is fixedly connected to the middle of the rubber pad and communicates with the sealing groove;

[0011] The injection occlusion mechanism includes a syringe and a threaded piston rod. The syringe is threadedly connected to the injection tube, and the threaded piston rod is threadedly connected to the syringe.

[0012] In one possible design, the fixing mechanism includes a fixed strap and a movable strap that are fixedly connected to both ends of the rubber pad. The other end of the fixed strap is fixedly connected to a fixed plate, and the other end of the fixed plate is fixedly connected to multiple hooks. The other end of the movable strap is fixedly connected to multiple retaining rings, which are detachably engaged with the hooks. The middle of the fixed plate is provided with a clamping component for clamping the chemical pipeline to enhance the fixing effect.

[0013] In one possible design, the clamping assembly includes a threaded push rod threaded through the middle of a fixed plate, with an arc-shaped push plate rotatably connected to the top of the threaded push rod, and multiple guide rods fixedly connected to the bottom of the arc-shaped push plate, the multiple guide rods sliding through the fixed plate.

[0014] In one possible design, a handle is fixedly connected to the bottom end of the threaded push rod, and a hexagonal slot is provided in the middle of the handle.

[0015] In one possible design, anti-slip pads are fixedly connected to the opposite sides of the curved push plate and the rubber pad.

[0016] In one possible design, the syringe includes a piston cylinder, a threaded cylinder, and an injection tube, with the threaded cylinder and the injection tube respectively fixedly connected to both ends of the piston cylinder, and the injection tube being threadedly connected to the injection tube.

[0017] In one possible design, the threaded piston rod includes a threaded rod, a T-shaped handle, and a piston. The threaded rod is threadedly connected to the threaded cylinder, and the piston is slidably sealed to the piston cylinder. The T-shaped handle and the piston are fixedly connected to both ends of the threaded rod.

[0018] In this application:

[0019] When a leak is discovered in a chemical pipeline, the operator cleans the surface of the leak point to prevent foreign objects from affecting the sealing effect. After cleaning, the operator first covers the leak point with the clamping side of the rubber pad, and then engages the clasp at one end of the movable strap with the hook at the other end of the fixed strap to achieve initial binding and fixation. To further enhance the fixation effect and prevent chemicals from leaking from the gaps in the rubber pad, the clamping assembly can be operated. By rotating the handle at the bottom of the threaded push rod, the arc-shaped push plate is driven to move towards the pipe wall until it is tightly attached to the pipe surface, forming a stable clamping force to ensure that the rubber pad is tightly attached to the pipe wall. During this process, the guide rod ensures the stability of the arc-shaped push plate movement and prevents it from deflecting.

[0020] After the rubber gasket is fixed, the sealing operation can be performed. The syringe pre-loaded with fast-curing sealant is connected to the injection tube fixed to the rubber gasket through its injection tube. The T-shaped handle of the threaded piston rod is rotated. Due to the engagement of the threaded rod with the threaded cylinder of the syringe, the rotational motion is converted into the linear forward motion of the piston in the piston cylinder, thus smoothly extruding the sealant. The extruded sealant is injected through the injection tube and fills the sealing groove on the clamping side of the rubber gasket. Under the pressure of the medium inside the pipeline, the sealant in the sealing groove is continuously pushed towards the leak point and quickly cures in the narrow sealing groove. Finally, a sealing layer composed of cured sealant is formed between the outer wall of the pipeline and the rubber gasket, as well as a sealing layer formed between the rubber gasket and the pipeline wall. The sealant layer further strengthens the sealing effect and prevents the leak point from leaking again.

[0021] Beneficial effects: In this utility model, the emergency sealing tool for chemical pipeline leaks uses a combination of components such as rubber pads, arc-shaped push plates, threaded push rods, and movable straps. The retaining ring at one end of the movable strap engages with the hook at the other end of the fixed strap to achieve initial binding and fixation. Rotating the handle at the bottom of the threaded push rod drives the arc-shaped push plate to move towards the pipe wall until it is tightly attached to the pipe surface, forming a stable clamping force. This ensures that the rubber pad is tightly attached to the pipe wall, quickly implementing physical sealing of the leak point. It has a fast response speed and is easy to operate.

[0022] In this utility model, an emergency sealing tool for chemical pipeline leaks is used in conjunction with components such as a syringe, a threaded piston rod, an injection tube, and a rubber pad. By rotating the T-shaped handle of the threaded piston rod, the rotational motion is converted into the linear forward motion of the piston within the piston cylinder due to the engagement of the threaded rod with the threaded cylinder of the syringe. This smoothly extrudes the sealant, which is then injected through the injection tube and fills the sealing groove on the clamping side of the rubber pad. Ultimately, a sealing layer composed of cured sealant is formed between the outer wall of the pipeline and the rubber pad, as well as a sealing layer formed between the rubber pad and the pipeline wall. The rubber pad adheres to the pipeline wall to form a physical seal, and the injected sealant provides a secondary seal at the leak point, further reinforcing the sealing effect.

[0023] In this invention, by rotating the threaded push rod, the rubber pad is driven to adhere to the pipe wall, and a physical seal is formed in a rapid response. The T-shaped handle of the rotating threaded piston rod smoothly squeezes the sealant into the sealing groove on the clamping side of the rubber pad, forming a gel-cured sealant at the leakage point, ensuring the reliability of the sealant.
