Description

Technical Field

[0001] The utility model relates to the technical field of heating, in particular to a flue pipe for a gas wall-mounted boiler which is convenient for replacement and maintenance. Background Art

[0002] The correct installation of the flue pipe of a gas wall-mounted boiler is very important and is related to the safety of the boiler. It must be highly emphasized that most of the wall-mounted boiler accidents at home and abroad are caused by flue gas leakage and gas leakage. The flue gas and gas contain highly poisonous gases such as colorless and odorless carbon monoxide that are harmful to the human body. As long as a person inhales a small amount of carbon monoxide, they will be poisoned.

[0003] When the existing wall-mounted boiler flue pipes are installed, in order to prevent leakage, an integrated pipeline design is mostly adopted. Such flue pipes have great limitations, are not flexible enough during installation, and are rather cumbersome during replacement and maintenance. Although the existing multi-section flue pipes are relatively flexible, leakage is likely to occur at the connection between each section of the pipeline. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the technical solution adopted by the utility model to solve its technical problems is: a flue pipe for a gas wall-mounted boiler which is convenient for replacement and maintenance, including:

[0005] A corrugated pipe; a collar, the inner wall of the collar is threadedly connected to the outer walls at both ends of the corrugated pipe; an anti-slip ring, the outer wall of the anti-slip ring is fixedly connected to the outer wall of the collar, and the anti-slip rings are arranged in a circular array along the outer wall of the collar;

[0006] The collars are symmetrically installed on the outer walls at both ends of the corrugated pipe. A pressing ring is fixedly connected to the outer wall of the corrugated pipe. A deformation groove is provided in the inner wall of the corrugated pipe. A slope is provided on the outer wall of the pressing ring, and a slope is provided on the inner wall of the collar, and the slopes provided on the pressing ring and the collar are equal.

[0007] A retaining ring is provided at the bottom of the deformation groove. A slot is provided in the inner wall of the top of the retaining ring. A rubber strip is fixedly connected inside the slot. An inner groove is provided outside the rubber strip. Connect both ends or any one end of the corrugated pipe to the gas exhaust pipeline. The flue gas is discharged from the inside of the corrugated pipe to the outside. When both ends of the corrugated pipe are connected to the outside, manually rotate the two collars, insert the external pipeline into the slot inside the retaining ring, and then lock the collars. The anti-slip rings increase the friction force by increasing the contact area, which is labor-saving and anti-slip.

[0008] Preferably, the outer wall of the snap ring is fixedly connected to the inner walls at both ends of the corrugated pipe. The inner groove is formed in the wall of the snap ring on the side away from the inner wall of the corrugated pipe, and an outer groove is formed in the wall of the snap ring on the side close to the inner wall of the corrugated pipe. When any end of the corrugated pipe is connected to an external pipeline, only by rotating a single collar, the locking can be completed. On the contrary, by rotating the collar in the reverse direction, the connection between the corrugated pipe and the smoke exhaust pipeline can be disconnected, which is convenient for quick disassembly, replacement and installation during maintenance. At the same time, the middle of the corrugated pipe can be bent appropriately to adapt to most environments, and the smoke exhaust direction can also be freely adjusted.

[0009] Preferably, both the inner groove and the outer groove are arranged annularly along the inner wall of the top of the snap ring, and the inner groove and the outer groove are staggered. The external pipeline is blocked by the snap ring, and its end face slides along the inclined surface of the slot to the top of the rubber strip. Under the action of pressure, the rubber strip is forced to bend and stretch downward, and the opening at the top of the slot decreases, and the inner wall of the slot further fits with the inner and outer walls of the external smoke exhaust pipeline.

[0010] Preferably, the inner walls at both ends of the corrugated pipe are fixedly connected with a bottom plate, and a top plate is arranged outside the bottom plate. The outer wall of the top plate is fixedly connected with a scraping strip. The inner groove and the outer groove are deformed to ensure that the opening at the top of the slot can be stably reduced. At the same time, due to the staggered arrangement of the inner groove and the outer groove, while ensuring the fit between the top of the snap ring and the external smoke exhaust pipeline, the gap between the two is reduced, improving the sealing effect.

[0011] Preferably, the outer wall of the top plate is fixedly connected to the inner wall of the corrugated pipe. Both the bottom plate and the top plate are arc-shaped ring structures. The scraping strips are arranged in an arc along the outer wall of the top plate away from the bottom plate. As the external smoke exhaust pipeline is inserted, the external pipeline first presses the top plate, and the scraping strip seals and slides with the external pipeline. And because the scraping strip is made of rubber, the scraping strip will tilt in the direction of the movement of the external smoke exhaust pipeline. Then rotate the collar. Since the slopes of the inner and outer walls of the collar and the pressure ring are equal, under the action of the threaded connection, the collar gradually approaches the pressure ring. The conical surface design forces the pressure ring to squeeze the corrugated pipe, and the deformation groove bends and contracts towards the snap ring. The bottom plate and the top plate are forced to fit and straighten, and the two are staggered. Through multi-stage sealing, while achieving quick disassembly and installation, it can further prevent the leakage of waste gas.

[0012] The beneficial effects of the present utility model are as follows:

[0013] By setting the corrugated pipe and the collar, the present utility model can realize the quick disassembly and installation of the corrugated pipe and the smoke exhaust pipeline by rotating the collar, which is convenient for maintenance and replacement. At the same time, a multi-stage sealing structure is adopted. When the collar is rotated, a conical structure is used to provide additional pressure, which is combined with the multi-stage sealing structure. While achieving quick disassembly and installation, it can ensure the sealing performance and prevent the waste gas from leaking into the room. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Embodiment:

[0023] Please refer to Figure 1 - Figure 6 , the present utility model provides a technical solution: a flue pipe for a gas wall-mounted boiler that is convenient for replacement and maintenance, comprising:

[0024] Corrugated pipe 1;

[0025] Collar 2, the inner wall of the collar 2 is threadedly connected to the outer walls of both ends of the corrugated pipe 1;

[0026] Anti-slip ring 3, the outer wall of the anti-slip ring 3 is fixedly connected to the outer wall of the collar 2, and the anti-slip rings 3 are arranged in a circular array along the outer wall of the collar 2;

[0027] The collars 2 are symmetrically installed on the outer walls of both ends of the corrugated pipe 1. A compression ring 4 is fixedly connected to the outer wall of the corrugated pipe 1. A deformation groove 5 is formed in the inner wall of the corrugated pipe 1. The outer wall of the compression ring 4 is provided with a slope, and the inner wall of the collar 2 is provided with a slope, and the slopes of the compression ring 4 and the collar 2 are equal.

[0028] A snap ring 6 is provided at the bottom of the deformation groove 5. An inner wall at the top of the snap ring 6 is provided with a slot 7. A rubber strip 8 is fixedly connected inside the slot 7, and an inner groove 9 is arranged outside the rubber strip 8.

[0029] The outer wall of the snap ring 6 is fixedly connected to the inner walls at both ends of the corrugated pipe 1. The inner groove 9 is opened in the wall of the snap ring 6 on the side away from the inner wall of the corrugated pipe 1, and an outer groove 10 is opened in the wall of the snap ring 6 on the side close to the inner wall of the corrugated pipe 1.

[0030] Both the inner groove 9 and the outer groove 10 are arranged annularly along the inner wall at the top of the snap ring 6, and the inner groove 9 and the outer groove 10 are arranged staggeredly.

[0031] The inner walls at both ends of the corrugated pipe 1 are fixedly connected with a bottom plate 11. An outer wall of the bottom plate 11 is provided with a top plate 12, and an outer wall of the top plate 12 is fixedly connected with a scraping strip 13.

[0032] The outer wall of the top plate 12 is fixedly connected to the inner wall of the corrugated pipe 1. Both the bottom plate 11 and the top plate 12 are arc-shaped ring structures, and the scraping strip 13 is arranged arc-shaped along the outer wall of the top plate 12 on the side away from the bottom plate 11.

[0033] Working principle:

[0034] During use, both ends or any one end of the corrugated pipe 1 is connected to the gas exhaust pipeline. The flue gas is discharged from the inside of the corrugated pipe 1 to the outside. When both ends of the corrugated pipe 1 are connected to the outside, manually rotate the two collar rings 2, insert the external pipeline into the slot 7 inside the snap ring 6, and then lock the collar rings 2. The anti-slip ring 3 increases the friction force by increasing the contact area, saving effort and preventing slipping. When any one end of the corrugated pipe 1 is connected to the external pipeline, only need to rotate a single collar ring 2 to complete the locking. On the contrary, rotate the collar ring 2 in the reverse direction to disconnect the connection between the corrugated pipe 1 and the exhaust pipeline, which is convenient for quick disassembly, replacement and installation during maintenance. At the same time, the middle of the corrugated pipe 1 can be bent appropriately to adapt to most environments, and the exhaust direction can also be freely adjusted;

[0035] When the external exhaust pipeline is inserted into the inside of the corrugated pipe 1, the external pipeline is blocked by the snap ring 6, and its end face slides along the inclined surface of the slot 7 to the top of the rubber strip 8. Under the action of pressure, the rubber strip 8 is forced to bend and stretch downward, and the opening at the top of the slot 7 decreases. The inner wall of the slot 7 further fits with the inner and outer walls of the external exhaust pipeline. During this process, the inner groove 9 and the outer groove 10 deform to ensure that the opening at the top of the slot 7 can stably become smaller. At the same time, due to the staggered arrangement of the inner groove 9 and the outer groove 10, while ensuring the fit between the top of the snap ring 6 and the external exhaust pipeline, the gap between the two is reduced, improving the sealing effect;

[0036] With the insertion of the external exhaust pipe, the external pipe first presses against the top plate 12, and the scraping strip 13 slides in a sealed manner with the external pipe. Since the scraping strip 13 is made of rubber, the scraping strip 13 will tilt in the direction of the movement of the external exhaust pipe. Subsequently, the collar 2 is rotated. Due to the equal slopes provided on the inner and outer walls of the collar 2 and the pressure ring 4, under the action of the threaded connection, the collar 2 gradually approaches the pressure ring 4. The conical surface design forces the pressure ring 4 to press against the corrugated pipe 1, and the deformation groove 5 bends and contracts towards the snap ring 6. The bottom plate 11 and the top plate 12 are forced to fit and straighten, and they are stagger-designed. Through multi-stage sealing, while achieving rapid disassembly and assembly, it can further prevent the leakage of waste gas.

[0037] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
