Detailed Description of the Preferred Embodiments

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] The present application discloses a fire damper for improving the connection sealing performance between the fire damper and the connecting pipeline.

[0031] Referring to Figure 1 、 Figure 2 , a fire damper includes a fire damper body 11. In actual use, since the fire damper body 11 is detachably installed at the smoke exhaust opening, there is a possibility of poor sealing effect. Therefore, both ends of the fire damper body 11 extend with mounting rings 12. The two mounting rings 12 are located at both ends of the fire damper body 11 along the direction of smoke flow. During the installation of the fire damper body 11, the mounting rings 12 at both ends of the fire damper body 11 are sleeved on the connecting pipeline. A sealing member is provided on the mounting ring 12, and the sealing member is used to seal the connection between the mounting ring 12 and the connecting pipeline. In this embodiment, the sealing member is a sealing ring 121. In order to adapt to the shape of the fire damper body 11 and facilitate processing and forming, both mounting rings 12 are square structures. The outer ring wall of the sealing ring 121 is used to connect with the inner ring wall of the mounting ring 12, and the inner ring wall of the sealing ring 121 is used to closely adhere to the outer wall of the connecting pipeline. Therefore, the sealing ring 121 is also a square structure. The mounting ring 12 is sleeved on the connecting pipeline, and the inner and outer ring walls of the sealing ring 121 are respectively in close contact with the mounting ring 12 and the connecting pipeline, improving the connection sealing performance between the fire damper and the connecting pipeline.

[0032] In order to reduce the probability that the sealing ring 121 falls off from the mounting ring 12 during the process of detaching the fire damper from the connecting pipeline, a sealing groove 122 for embedding the sealing ring 121 is provided in the mounting ring 12. The sealing groove 122 is provided in a full circle along the circumferential direction of the mounting ring 12. The sealing ring 121 is filled in the sealing groove 122. When the mounting ring 12 is not sleeved on the connecting pipeline, a part of the sealing ring 121 is exposed outside the sealing groove 122. Since the sealing ring 121 is made of an elastic material, when the mounting ring 12 is sleeved on the connecting pipeline, the sealing ring 121 is completely embedded into the sealing groove 122, and the side of the sealing ring 121 away from the bottom of the sealing groove 122 is closely attached to the outer wall of the connecting pipeline.

[0033] In order to facilitate the installation workers to judge whether the fire damper is installed in place, at least one positioning member 13 is provided in the mounting ring 12. A plurality of positioning members 13 are arranged at intervals along the circumferential direction of the mounting ring 12 on the inner ring wall of the mounting ring 12. In this embodiment, three positioning members 13 are provided on the inner ring walls of the four sides of the mounting ring 12, and the three positioning members 13 are arranged at equal distances and intervals on each side of the inner ring wall of the mounting ring 12. The positioning member 13 is used for embedding into the corresponding positioning hole on the connecting pipeline.

[0034] Specifically, the positioning member 13 includes a positioning block 131 and a positioning spring 132. A positioning groove 123 for embedding the positioning member 13 is provided on the inner ring wall of the mounting ring 12. One end of the positioning spring 132 is connected to the bottom of the positioning groove 123, and the other end of the positioning spring 132 is connected to the positioning block 131. A part of the positioning block 131 is located in the positioning groove 123. During the process of sleeving the mounting ring 12 on the connecting pipeline, the positioning spring 132 is compressed, and the positioning block 131 is completely embedded into the positioning groove 123. When the positioning block 131 is aligned with the positioning hole provided on the connecting pipeline, the elastic force of the positioning spring 132 causes the positioning block 131 to be embedded into the positioning hole, that is, the installation between the mounting ring 12 and the connecting pipeline is in place.

[0035] In order to further improve the connection sealing performance between the fire damper and the connecting pipeline, a clamp is sleeved on the mounting ring 12. The clamp includes two tightening half rings 14. The two tightening half rings 14 are connected end to end and jointly sleeved on the mounting ring 12. Tightening members 15 are provided at both ends of the tightening half ring 14. The tightening member 15 includes a tightening bolt 151 and a tightening nut 152. The tightening nut 152 is sleeved on the tightening bolt 151. The tightening bolt 151 sequentially passes through the two tightening half rings 14 and is threadedly connected to the tightening nut 152. After the two tightening half rings 14 are sleeved on the mounting ring 12, the tightening bolt 151 sequentially passes through the two tightening half rings 14 and is threadedly connected to the tightening nut 152 to complete the installation of the tightening member 15, further improving the connection sealing performance between the fire damper and the connecting pipeline.

[0036] Reference Figure 2 、 Figure 3, Further, a contact spring 141 is sleeved on the tightening bolt 151. The two ends of the contact spring 141 are respectively used to contact the opposite sides of the two tightening half-rings 14. The two ends of the contact spring 141 respectively contact the two ends of the two tightening springs, so that the tightening half-rings 14 are kept in a state of tightly holding the mounting ring 12.

[0037] The implementation principle of a fire damper in an embodiment of this application is as follows: The mounting ring 12 is sleeved on the connecting pipeline, and the inner and outer ring walls of the sealing ring 121 are respectively in close contact with the mounting ring 12 and the connecting pipeline, improving the connection tightness between the fire damper and the connecting pipeline; after the two tightening half-rings 14 are sleeved on the mounting ring 12, the tightening bolt 151 sequentially passes through the two tightening half-rings 14 and is threadedly connected to the tightening nut 152 to complete the installation of the tightening member 15, further improving the connection tightness between the fire damper and the connecting pipeline.

[0038] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
