Description

Technical Field

[0001] This utility model relates to the technical field of corrugated compensators for heating pipelines, specifically a pipeline compensator for heating pipelines that can be used for pressurized leak sealing. Background Technology

[0002] Pipeline compensators are mainly used to compensate for the thermal expansion and contraction of pipelines caused by temperature changes. If the pipeline cannot expand or contract freely when the temperature changes, and a leak occurs between the heating pipeline and the corrugated compensator, the current method of sealing the leak is to make a clamp with the same outer diameter as the leaking pipe and seal the leak by injecting glue or pressing.

[0003] According to a public announcement of a pressure-sealing device for a corrugated compensator for a heating pipeline (Announcement No.: CN219082580U), the above application includes a heating pipeline, a corrugated compensator body, and an annular plate sleeved on the corrugated compensator body. One end of the heating pipeline is located inside the annular plate. An annular groove is formed on the inner wall surface of the annular plate, and a telescopic airbag is provided inside the annular groove.

[0004] However, in actual use, the airbag, as a compaction element, is exposed to high temperature and high pressure environment for a long time, especially when it is close to the heat source of the corrugated compensator. It is prone to thermal aging, which can lead to rupture when the pressure is uneven or the gas is overfilled. Once it fails, the sealing force will also fail. In view of this, we propose a pipe compensator for heating pipelines that can be used for pressurized leak sealing. Utility Model Content

[0005] The purpose of this invention is to provide a pipe compensator for heating pipelines that can be used for pressurized leak sealing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe compensator for heating pipelines capable of pressure-sealing leaks, comprising a pipe compensator body, a heating pipeline body fixedly connected to the end face of the pipe compensator body, and a leak-sealing component provided on the end face of the pipe compensator body, the leak-sealing component comprising: A ring body, the inner wall of which is fixedly connected to a temporary storage box, the side wall of which has a drain outlet and a slide rail. A baffle is provided, with a sealing ring fixedly connected to its inner top surface, a slider fixedly connected to its side wall, and a spring fixedly connected to its inner top surface.

[0007] Preferably, the ring is fixedly connected to the side wall of the pipe compensator body, and the inner wall of the ring abuts against the outer wall of the heating pipe body.

[0008] Preferably, the baffle abuts against the outer wall of the heating pipe body, and the baffle contacts the connection between the pipe compensator body and the heating pipe body.

[0009] Preferably, the slider is slidably connected to the slide rail, and the temporary storage box is movably connected to the side wall of the baffle, with the temporary storage box blocking the outlet.

[0010] Preferably, the sealing ring is movably connected to the inner wall of the ring body and to the side wall of the temporary storage box, thereby improving the sealing performance of the device.

[0011] Preferably, one end of the spring is fixedly connected to the inner top surface of the baffle, and the end of the spring away from the baffle is fixedly connected to the inner wall of the ring.

[0012] Preferably, a sleeve is fixedly connected to the inner wall of the ring, and the sleeve is connected to the inner wall of the movable column, which is fixedly connected to the inner top surface of the baffle.

[0013] Compared with the prior art, this utility model provides a pipe compensator for heating pipelines that can be pressurized and leak-stopped, which has the following advantages: 1. This pressurized leak-sealing pipe compensator for heating pipelines allows polyurethane injection material inside the temporary storage box to flow into the ring body through the designed leak-sealing component. The polyurethane combines with water and cures without the need for electrical control, sensors, or human operation. The leak itself becomes the trigger signal, giving the structure a self-healing function. The polyurethane adhesive is only released at the actual leak location, ensuring precise positioning and avoiding ineffective injection or adhesive waste. The sealing ring improves the device's sealing performance, preventing the polyurethane from failing to effectively seal the connection between the pipe compensator body and the heating pipeline body after release, and preventing material from leaking into unrelated parts. The spring, through its elastic deformation, ensures that the polyurethane injection material can be stably and fully released after triggering, allowing the adhesive to accurately seal the leak location at the connection between the pipe compensator body and the heating pipeline body.

[0014] 2. This pressurized leak-sealing pipe compensator for heating pipelines, through its movable column, extends outward from the ring body after a leak occurs, quickly locating the leak point. This avoids maintenance personnel blindly inspecting the entire pipeline or equipment, saving a significant amount of time and labor costs. Maintenance personnel can then perform targeted repairs, avoiding ineffective disassembly and repeated work. Attached Figure Description

[0017] like Figures 1-5 As shown, this utility model provides a technical solution: a pipe compensator for heating pipelines that can be pressurized and leak-stopped, including a pipe compensator body 1, a heating pipeline body 2 fixedly connected to the end face of the pipe compensator body 1, and a leak-stopping component 3 provided on the end face of the pipe compensator body 1. The leak-stopping component 3 includes a ring 301, a temporary storage box 302, a discharge port 303, a slide rail 304, a baffle 305, a slider 306, a spring 307, and a sealing ring 308.

[0018] In one embodiment of this utility model, the ring 301 is fixedly connected to the side wall of the pipe compensator body 1, the inner wall of the ring 301 abuts against the outer wall of the heating pipe body 2, a temporary storage box 302 is fixedly connected to the inner wall of the ring 301, an outlet 303 is opened on the side wall of the temporary storage box 302, and a slide rail 304 is opened on the side wall of the temporary storage box 302.

[0019] The baffle 305 abuts against the outer wall of the heating pipe body 2 and contacts the connection between the baffle 305 and the pipe compensator body 1 and the heating pipe body 2. A sealing ring 308 is fixedly connected to the inner top surface of the baffle 305. A slider 306 is fixedly connected to the side wall of the baffle 305. The slider 306 is slidably connected to the slide rail 304. The temporary storage box 302 is movably connected to the side wall of the baffle 305 and blocks the outlet 303. A spring 307 is fixedly connected to the inner top surface of the baffle 305. The end of the spring 307 away from the baffle 305 is fixedly connected to the inner wall of the ring body 301. The sealing ring 308 is movably connected to the inner wall of the ring body 301 and the side wall of the temporary storage box 302. The sealing ring 308 improves the sealing performance of the device.

[0020] When a leak occurs at the connection between the pipe compensator body 1 and the heating pipe body 2, the leaking hot water or steam pushes the baffle 305 towards the inner wall of the ring 301. The slider 306 slides along the slide rail 304, thereby exposing the outlet 303. The polyurethane injection material inside the temporary storage box 302 flows into the ring 301. The polyurethane combines with water and cures, and expands due to heat. Without the need for electrical control, sensors, or human operation, the leak itself becomes a trigger signal, enabling the structure to have a self-healing function. The polyurethane adhesive is only released at the actual leak location, accurately positioning the injection and avoiding ineffective injection or waste of adhesive.

[0021] The sealing ring 308 improves the sealing performance of the device, preventing the polyurethane in the temporary storage box 302 from leaking before triggering, protecting the material from premature contamination or contact with moisture, and preventing the polyurethane from failing to effectively seal the connection between the pipe compensator body 1 and the heating pipe body 2 after release, and instead leaking into unrelated parts. The spring 307, through its elastic deformation, pushes the colloid to achieve quantitative injection, ensuring that the polyurethane injection material can be released stably and fully after triggering, so that the colloid accurately seals the leaking position at the connection between the pipe compensator body 1 and the heating pipe body 2.

[0022] In addition, a sleeve 4 is fixedly connected to the inner wall of the ring 301. The sleeve 4 is connected to the inner wall of the movable column 5. The movable column 5 is fixedly connected to the inner top surface of the baffle 305. After a leak occurs, the colloid expands and seals the gap between the baffle 305 and the heating pipe body 2, causing the movable column 5 to extend to the outside of the ring 301, quickly locating the leak point. This avoids maintenance personnel blindly checking the entire pipeline or equipment, saving a lot of time and manpower costs. Maintenance personnel can carry out targeted repairs, avoiding ineffective disassembly and repeated work.

[0023] In this invention, when a leak occurs at the connection between the pipe compensator body 1 and the heating pipe body 2, the leaking hot water or steam pushes the baffle 305 towards the inner wall of the ring 301. The slider 306 slides along the slide rail 304, thereby exposing the outlet 303. The polyurethane injection material inside the temporary storage box 302 flows into the ring 301. The polyurethane combines with water, solidifies, and expands due to heat. It is released only at the actual leak location, accurately positioning the injection and avoiding ineffective injection or waste of adhesive. The spring 307, through its elastic deformation, pushes the adhesive to achieve quantitative injection, ensuring that the polyurethane injection material can be released stably and fully after triggering, so that the adhesive accurately seals the leak at the connection between the pipe compensator body 1 and the heating pipe body 2.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
