Description

Technical Field

[0001] This utility model relates to the field of fire damper technology, and in particular to a corrosion-resistant fire damper resistant to 150 degrees Celsius. Background Technology

[0002] The corrosion-resistant 150°C fire damper is a special valve installed on ducts of ventilation, air conditioning, or smoke exhaust systems. It can withstand corrosive environments under normal operating conditions and automatically closes when the airflow temperature inside the duct reaches 150°C to prevent the spread of fire.

[0003] Chinese Patent Publication No. CN218818407U, published on April 7, 2023, discloses a smoke exhaust fire damper, comprising: a main body; the main body is the smoke exhaust fire damper body, a controller is provided at the top of the main body, a rotating shaft is installed inside the main body, a sealing plate is provided on the outside of the rotating shaft, a movable component is installed on each side of the sealing plate, the movable component is a rectangular structure, an arc-shaped groove is provided on the inner side of each movable component, the rotating shaft is embedded in the arc-shaped groove, a collection groove is provided at each end of each movable component, the collection groove is a rectangular structure inside, and the inner side of the top of the collection groove is an inclined structure; and two side components, which are T-shaped plate structures, are provided in total, and the two side components are respectively located on both sides of the main body and are embedded in the installation groove.

[0004] Existing corrosion-resistant 150°C fire dampers mostly use temperature sensors to detect temperature. When the temperature exceeds a threshold, the actuator drives one set of rotating blocks to rotate. The two sets of rotating blocks are linked by a linkage mechanism, which in turn drives two sets of sealing plates to be placed horizontally. In practice, the sealing plates are usually directly fixed to the rotating blocks, making it difficult to independently disassemble and replace them later. Therefore, there is an urgent need to develop a corresponding corrosion-resistant 150°C fire damper to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a corrosion-resistant 150-degree fireproof valve to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The corrosion-resistant 150-degree fireproof valve includes a valve body, a sealing plate, an actuating unit, and two sets of rotating blocks. The two sets of rotating blocks are driven and cooperated by a linkage mechanism. A bottom chamber is fixedly connected to the bottom of the valve body. The bottom chamber integrates a bottom plate and a lifting component for pushing the bottom plate to move vertically. Two sets of supports are fixedly connected to the top of the bottom plate. The two sets of sealing plates are integrated between the two sets of rotating blocks and the supports.

[0008] Preferably, a raised edge is fixedly connected to the top of the bottom compartment, and an outer edge is fixedly connected to the outer wall of the bottom of the bottom plate.

[0009] Preferably, the lifting assembly includes a transmission rod rotatably connected to the inner surface wall of the bottom of the compartment, and the outer surface wall of the transmission rod is screwed into the inner surface wall of the bottom plate.

[0010] Preferably, a top block is fixedly connected to the top of the transmission rod, and the top of the top block has a cross pattern.

[0011] Preferably, the top of the base plate has an inner groove that fits with the top block, and the top of the top block and the top of the base plate are located on the same horizontal plane.

[0012] Preferably, the top of the sealing plate is provided with a slot, and the outer wall of the rotating block engages with the top of the sealing plate through the slot.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the clearance space created by the downward movement of the base plate allows the sealing plate to be connected to the rotating block upwards. Then, the top block is connected by an auxiliary tool such as a starter, which drives the top block and the transmission rod to rotate. The transmission rod provides a pushing force to the base plate by screwing into the inner surface of the base plate, causing the base plate to move upwards a corresponding distance. At this time, the support at the top of the base plate is connected to the bottom of the sealing plate, thus realizing the composition of the sealing plate. The execution unit drives one set of rotating blocks to rotate, and the two sets of rotating blocks are driven by a linkage mechanism. The two sets of rotating blocks drive the two sets of sealing plates to close, thus ensuring the normal and stable opening and closing of the sealing plate while improving the convenience of independent disassembly and assembly of the sealing plate.

[0015] 2. In this application, the base plate drives the outer edge to rise synchronously until the outer edge touches the bottom of the protruding edge. At this point, the base plate can no longer rise, and the support is perfectly matched with the bottom of the sealing plate. This allows for accurate control of the rising position of the base plate, thereby further improving the ease of use of the corrosion-resistant 150-degree fireproof valve.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] The corrosion-resistant 150-degree fireproof valve includes a valve body 1, a sealing plate 2, an actuation unit and two sets of rotating blocks 12. The two sets of rotating blocks 12 are driven and cooperated by a linkage mechanism. A bottom chamber 3 is fixedly connected to the bottom of the valve body 1. The bottom chamber 3 integrates a bottom plate 6 and a lifting component for pushing the bottom plate 6 to move vertically. Two sets of supports 4 are fixedly connected to the top of the bottom plate 6. The two sets of sealing plates 2 are integrated between the two sets of rotating blocks 12 and the supports 4.

[0025] The clearance created by the downward movement of the base plate 6 allows the sealing plate 2 to be joined to the rotating block 12. Then, using auxiliary tools such as a starter, the top block 7 is engaged, causing the top block 7 and the transmission rod 5 to rotate. The transmission rod 5 provides a pushing force to the base plate 6 by engaging with the inner surface of the base plate 6, causing the base plate 6 to move upward a corresponding distance. At this time, the support 4 at the top of the base plate 6 is fitted onto the bottom of the sealing plate 2, thus completing the assembly of the sealing plate 2. The execution unit drives one set of rotating blocks 12 to rotate, and the two sets of rotating blocks 12 are driven by a linkage mechanism to close the two sets of sealing plates 2. This ensures the normal and stable opening and closing of the sealing plate 2 while improving the convenience of independent assembly and disassembly of the sealing plate 2.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, a raised edge 10 is fixedly connected to the top of the bottom compartment 3, and an outer edge 11 is fixedly connected to the bottom outer wall of the bottom plate 6. The bottom plate 6 drives the outer edge 11 to rise synchronously until the outer edge 11 touches the bottom of the raised edge 10. At this time, the bottom plate 6 can no longer rise, and the support 4 is completely engaged with the bottom of the sealing plate 2. This allows for accurate control of the rising position of the bottom plate 6, thereby further improving the ease of use of the corrosion-resistant 150-degree fireproof valve.

[0027] Specifically, such as Figure 2 and Figure 3As shown, the lifting assembly includes a transmission rod 5 rotatably connected to the inner surface of the bottom of the base 3. The outer surface of the transmission rod 5 is screwed onto the inner surface of the base plate 6. A top block 7 is fixedly connected to the top of the transmission rod 5. The top of the top block 7 has a cross pattern. By using an auxiliary tool such as a starter to engage the top block 7, the top block 7 and the transmission rod 5 can be rotated. The transmission rod 5 provides a pushing force to the base plate 6 by screwing onto the inner surface of the base plate 6. The top of the base plate 6 has an inner groove 9 that fits with the top block 7, and the top of the top block 7 and the top of the base plate 6 are on the same horizontal plane to prevent the top block 7 from protruding. The top of the sealing plate 2 has a slot 8. The outer surface of the rotating block 12 engages with the top of the sealing plate 2 through the slot 8, ensuring axial linkage between the two while ensuring easy separation of the two.

[0028] Working principle: The clearance space created by the downward movement of the base plate 6 allows the sealing plate 2 to be connected to the rotating block 12. Then, using auxiliary tools such as a starter to connect with the top block 7, the top block 7 and the transmission rod 5 are rotated. The transmission rod 5 provides a pushing force to the base plate 6 by screwing it onto the inner wall of the base plate 6, causing the base plate 6 to move upward a corresponding distance. At this time, the support 4 on the top of the base plate 6 is fitted onto the bottom of the sealing plate 2, thus completing the assembly of the sealing plate 2. The execution unit drives one set of rotating blocks 12 to rotate. The two sets of rotating blocks 12 are driven by a linkage mechanism, and the two sets of rotating blocks 12 drive the two sets of sealing plates 2 to close. This ensures the normal and stable opening and closing of the sealing plate 2, while improving the convenience of independent assembly and disassembly of the sealing plate 2. The base plate 6 drives the outer edge 11 to rise synchronously until the outer edge 11 abuts against the bottom of the protruding edge 10. At this time, the base plate 6 can no longer rise, and the support 4 is perfectly engaged with the bottom of the sealing plate 2. This allows for accurate control of the rising position of the base plate 6, thereby further improving the ease of use of the corrosion-resistant 150-degree fireproof valve.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
