Description

Technical Field

[0001] This utility model relates to the field of hot water boiler technology, specifically to a flue pipe connection structure for a gas-fired heating hot water boiler. Background Technology

[0002] Gas-fired heating and hot water boilers are widely used in modern homes for heating and hot water supply. They generate heat by burning gas to meet people's needs for indoor heating and domestic hot water. During the operation of a gas-fired heating and hot water boiler, the flue plays a crucial role. It is responsible for venting the exhaust gas produced by combustion to the outside while ensuring that outside air can enter the boiler body normally to maintain the combustion process. The stability and sealing of the flue connection are directly related to the safe operation and efficiency of the gas-fired heating and hot water boiler.

[0003] Traditional flue pipe connections often employ a simple plug-in method, such as directly inserting two flue pipes together. This connection method lacks an effective fixing structure. During the operation of the gas-fired heating and hot water boiler, the flue pipes can easily detach due to machine vibration or minor external impacts or pulling. Once the flue pipes detach, not only will the gas-fired heating and hot water boiler malfunction, but the exhaust gases produced during combustion will also leak into the room, posing a serious threat to the health and safety of people indoors. Furthermore, in actual use, it is difficult to achieve a completely tight fit at the plug-in joint, which makes it easy for exhaust gases to leak out from the connection point.

[0004] Therefore, a flue pipe connection structure for a gas-fired heating and hot water boiler is provided to address the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a flue pipe connection structure for a gas-fired heating and hot water boiler, so as to solve the problems mentioned in the background art where the flue pipe connection is not tight enough and the sealing effect is poor.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a flue pipe connection structure for a gas-fired heating hot water boiler, comprising a hot water boiler body, a first flue pipe mounted on the upper surface of the hot water boiler body, a threaded connecting pipe fixedly mounted on the outer surface of the first flue pipe, a first abutting ring fixedly mounted on the outer surface of the first flue pipe, the first abutting ring being disposed at one end of the first flue pipe, a first sealing ring fixedly mounted inside the first abutting ring, a second flue pipe disposed above the first flue pipe, a connecting mechanism fixedly mounted on the outer surface of the second flue pipe, a second abutting pipe fixedly mounted on the outer surface of the second flue pipe, and a second sealing ring fixedly mounted inside the second abutting pipe.

[0008] Furthermore, the connecting mechanism includes a fixing plate, and the fixing plate is symmetrically installed on the outer surface of the second smoke pipe.

[0009] Furthermore, the connecting mechanism also includes a sliding groove, and the outer surface of the fixing plate is provided with a sliding groove.

[0010] Furthermore, the connecting mechanism also includes a movable plate, which is fixedly installed on the outer surface of the second smoke pipe.

[0011] Furthermore, the connecting mechanism also includes a slider and a threaded connection cover. Two sets of sliders are fixedly installed on the inner wall of the movable plate. The two sets of sliders are slidably connected to the interior of two sets of sliding grooves respectively. The inner wall of the movable plate is rotatably connected to a threaded connection cover, and the threaded connection cover is threadedly connected to a threaded connection pipe.

[0012] Furthermore, the first abutting ring and the second abutting pipe are connected to each other, and the first sealing ring and the second sealing ring abut against each other.

[0013] This utility model has the following beneficial effects:

[0014] (1) This utility model aligns the connecting mechanism of the second flue with the first flue, and then adjusts the position of the movable plate by sliding the slider on the inner wall of the movable plate in the groove on the outer surface of the fixed plate, so that the threaded connecting cover can accurately correspond to the threaded connecting pipe on the outer surface of the first flue. Then, the threaded connecting cover is rotated. Since the threaded connecting cover is threadedly connected to the threaded connecting pipe, as the threaded connecting cover rotates, the second flue will gradually approach the first flue until the first abutting ring and the second abutting pipe are connected. When the first abutting ring and the second abutting pipe are connected, the first sealing ring inside the first abutting ring and the second sealing ring inside the second abutting pipe abut against each other, thus forming a seal at the connection between the first flue and the second flue, thereby achieving the installation and sealing of the first flue and the second flue, avoiding the situation where the first flue and the second flue are easily detached during the plug-in installation and the gas heating hot water boiler is prone to exhaust gas leakage during operation due to poor sealing effect.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 5 As shown, this utility model is a flue pipe connection structure for a gas-fired heating hot water boiler, including a hot water boiler body 1, a first flue pipe 2 installed on the upper surface of the hot water boiler body 1, a threaded connecting pipe 3 fixedly installed on the outer surface of the first flue pipe 2, a first abutting ring 4 fixedly installed on the outer surface of the first flue pipe 2, the first abutting ring 4 being disposed at one end of the first flue pipe 2, a first sealing ring 401 fixedly installed inside the first abutting ring 4, a second flue pipe 5 disposed above the first flue pipe 2, a connecting mechanism 6 fixedly installed on the outer surface of the second flue pipe 5, a second abutting pipe 7 fixedly installed on the outer surface of the second flue pipe 5, and a second sealing ring 701 fixedly installed inside the second abutting pipe 7;

[0026] The connecting mechanism 6 includes a fixing plate 601, and the fixing plate 601 is symmetrically installed on the outer surface of the second smoke pipe 5;

[0027] The connecting mechanism 6 also includes a slide groove 602, and the outer surface of the fixing plate 601 is provided with a slide groove 602;

[0028] The connecting mechanism 6 also includes a movable plate 603, which is fixedly installed on the outer surface of the second smoke pipe 5;

[0029] The connecting mechanism 6 also includes a slider 604 and a threaded connection cover 605. Two sets of sliders 604 are fixedly installed on the inner wall of the movable plate 603. The two sets of sliders 604 are slidably connected to the interior of the two sets of sliding grooves 602 respectively. The inner wall of the movable plate 603 is rotatably connected to the threaded connection cover 605, and the threaded connection cover 605 is threadedly connected to the threaded connection pipe 3.

[0030] The first abutting ring 4 and the second abutting pipe 7 are connected to each other, and the first sealing ring 401 and the second sealing ring 701 are abutted to each other;

[0031] When it is necessary to connect the first smoke pipe 2 and the second smoke pipe 5, first align the connecting mechanism 6 of the second smoke pipe 5 with the first smoke pipe 2. Then, adjust the position of the movable plate 603 by sliding the slider 604 on the inner wall of the movable plate 603 within the groove 602 on the outer surface of the fixed plate 601, so that the threaded connection cover 605 can accurately correspond to the threaded connection pipe 3 on the outer surface of the first smoke pipe 2. Then, rotate the threaded connection cover 605. Since the threaded connection cover 605 is threadedly connected to the threaded connection pipe 3, the second smoke pipe 5 will gradually... Approaching the first flue pipe 2, until the first abutting ring 4 and the second abutting pipe 7 are aligned, when the first abutting ring 4 and the second abutting pipe 7 are aligned, the first sealing ring 401 inside the first abutting ring 4 and the second sealing ring 701 inside the second abutting pipe 7 abut against each other, thus forming a seal at the connection between the first flue pipe 2 and the second flue pipe 5, thereby achieving the installation and sealing of the first flue pipe 2 and the second flue pipe 5, avoiding the easy detachment of the first flue pipe 2 and the second flue pipe 5 during installation, and the easy occurrence of exhaust gas leakage during the operation of the gas-fired heating hot water boiler due to poor sealing effect.

[0032] In use, when connecting the first smoke pipe 2 and the second smoke pipe 5, first align the connecting mechanism 6 of the second smoke pipe 5 with the first smoke pipe 2. Then, adjust the position of the movable plate 603 by sliding the slider 604 on the inner wall of the movable plate 603 within the groove 602 on the outer surface of the fixed plate 601, so that the threaded connection cover 605 can accurately correspond to the threaded connection pipe 3 on the outer surface of the first smoke pipe 2. Then, rotate the threaded connection cover 605. Since the threaded connection cover 605 is threadedly connected to the threaded connection pipe 3, as the threaded connection cover 605 rotates, the second smoke pipe 5 will gradually... The pipe gradually approaches the first flue pipe 2 until the first abutting ring 4 and the second abutting pipe 7 come into contact. When the first abutting ring 4 and the second abutting pipe 7 come into contact, the first sealing ring 401 inside the first abutting ring 4 and the second sealing ring 701 inside the second abutting pipe 7 abut against each other. This forms a seal at the connection between the first flue pipe 2 and the second flue pipe 5, thereby achieving the installation and sealing of the first flue pipe 2 and the second flue pipe 5. This avoids the situation where the first flue pipe 2 and the second flue pipe 5 are easily detached during plug-in installation and the gas-fired heating hot water boiler is prone to exhaust gas leakage due to poor sealing effect.
