DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0027] As shown in Figure 1 - Figure 5 The smoke and fireproof valve mainly comprises a first valve frame 1, a second valve frame 2, a movable cavity 3, a valve plate 4 and a transmission device 5. The valve frame serves as the framework of the whole valve and is composed of the first valve frame 1 and the second valve frame 2 to form a firm square valve seat. The valve plate 4 is ingeniously installed in the movable cavity 3 formed by the two frames and can be flexibly opened and closed to ensure that the propagation path of smoke and fire can be quickly cut off when a fire occurs.

[0028] The fireproof performance of the valve is greatly improved. On the outside of the second valve frame 2, a quick-mount cover 6 is designed skillfully, which not only facilitates installation and maintenance, but also significantly enhances the fireproof ability of the valve. Inside the quick-mount cover 6, from inside to outside, there are a second honeycomb fireproof layer plate 10, a first honeycomb fireproof layer plate 9, and a cover 8. The honeycomb structure has unique advantages, not only increasing the surface area of the fireproof material and improving the fireproof effect, but also having good heat insulation performance, which can effectively block the invasion of high-temperature heat sources in a fire.

[0029] The end faces of the first honeycomb fireproof layer plate 9 and the second honeycomb fireproof layer plate 10 are skillfully provided with filler compartments 11. These filler compartments 11 are filled with high-quality fireproof materials such as glass wool, rock wool, or aluminum silicate fiber felt. These materials not only have good fireproof performance, but also have excellent heat and sound insulation effects, further improving the overall fireproof ability of the valve.

[0030] In addition, the quick-mount cover 6 is tightly connected with the first valve frame 1 through fastening bolts 7, and the cover 8 is connected with the second valve frame 2 in the same way. This connection method is not only firm and reliable, but also facilitates disassembly and replacement of parts. At the same time, the quick-mount cover 6 and the cover 8 also adopt a limiting connection method, ensuring the stable installation of the honeycomb fireproof layer plate.

[0031] The connection between the first valve frame 1 and the second valve frame 2 is also provided with a high-temperature-resistant sealing strip. This design not only enhances the sealing performance of the valve, but also maintains stable sealing effect in high-temperature environment. The end face of the high-temperature-resistant sealing strip is also provided with round holes, which are opposite to the end face thread holes of the first valve frame 1, facilitating the installation and fixation of the sealing strip.

[0032] The design of the quick-mount cover 6 is also unique. It adopts a "U" shape design, with a notch opposite to the transmission device 5, which not only facilitates the installation and maintenance of the transmission device 5, but also improves the overall aesthetics. At the same time, the quick-mount cover 6 and the cover 8 are connected through embedding blocks and slots, which is not only simple and convenient, but also has good stability.

[0033] In terms of material selection, the first honeycomb fireproof layer plate 9 and the second honeycomb fireproof layer plate 10 respectively adopt any one of gypsum board, rock wool board, or silicate composite board. These materials not only have good fireproof performance, but also have excellent high-temperature resistance and corrosion resistance. The valve plate 4 adopts a composite board composed of rock wool board, silicate composite board, and outer metal plate. This composite board not only has good fireproof performance, but also has high strength and rigidity, and can maintain stable structural performance in high-temperature environment.

[0034] It can not only effectively block the spread of smoke and fire, but also maintain stable operation in high temperature environment.

[0035] The installation process is as follows: confirm the installation location and environment, prepare the required tools and materials, such as fastening bolts 7, fireproof materials in the packing chamber 11, such as glass wool, rock wool or aluminum silicate fiber felt.

[0036] The first valve frame 1 and the second valve frame 2 are firmly connected together through high-temperature-resistant sealing strips, which are not directly numbered but are mentioned in the description as corresponding connection methods such as threaded holes and round holes. Ensure that the sealing strips are installed in place to enhance sealing performance. Install the quick-mount cover 6 on the outside of the second valve frame 2, and then install the second honeycomb fireproof layer plate 10 and the first honeycomb fireproof layer plate 9 inside the quick-mount cover 6. Ensure that the layer plates are tightly fitted and that the packing chamber 11 at the end is filled with fireproof material.

[0037] Use fastening bolts 7 to firmly connect the quick-mount cover 6 with the first valve frame 1. At the same time, the cover 8 is connected with the second valve frame 2 through fastening bolts 7 or other methods. Ensure that all connections are tight and have no looseness. The valve plate 4 is skillfully installed in the movable cavity 3 formed by the first valve frame 1 and the second valve frame 2. Then, the transmission device 5 is installed and ensured to smoothly drive the valve plate 4 to open and close.

[0038] Ensure that the quick-mount cover 6 and the cover 8 are connected through limit connection structures such as blocks and grooves to improve the overall stability. At the same time, make fine adjustments as needed to ensure that the functions of the valve are normal. After the installation is completed, perform a function test, including the opening and closing speed of the valve, fireproof performance, etc. Ensure that all indicators meet the design requirements before it can be formally put into use. This smoke and fireproof valve can be successfully installed and put into use, providing strong protection for fire safety.
