Description
Technical Field
[0001] This utility model belongs to the technical field of smoke and fire prevention regulating valves, specifically relating to a novel smoke and fire prevention regulating valve. Background Technology
[0002] Smoke and fire prevention regulating valves are used in horizontal ducts passing through walls and vertical ducts passing through floors in ventilation and air conditioning systems with fire protection requirements. In the event of a fire, the actuator automatically closes the valve when the temperature sensor is activated, or the valve is closed manually by the control center outputting 24V power to prevent the fire from spreading along the duct. They are normally open. Traditional smoke and fire prevention regulating valves rely on electronic components to control the blades to open and close. These electronic components are prone to failure at high temperatures, posing a safety hazard. The blades are connected by rotation and have low impact resistance. The blades still occupy a large space when opening and closing, and the air duct is still severely blocked.
[0003] The patent document publication number is: "CN211059376U A novel smoke and fire prevention regulating valve, relating to the field of regulating valve technology, aims to solve the problem of poor sealing and easy smoke leakage caused by insufficient connection strength between blades in the prior art. Its key technical points are: it includes a valve body with a flow channel and several blades rotatably connected to the valve body; a control device for driving the blades to rotate is provided on the outer wall of the valve body; its characteristic is that: a reinforcing plate is detachably connected to one side of the blade along the blade length direction; a polygonal prism-shaped connecting channel is provided on the side of the reinforcing plate where the blades fit; a connecting post matching the connecting channel is provided in the connecting channel; and the two ends of the connecting post are rotatably connected to the valve body." One side of the reinforcing plate has several arrayed grooves, and one side of the blade has a block for embedding into the grooves. This invention, by setting a reinforcing plate and engaging it with the blade, achieves better connection strength and sealing between adjacent blades. However, the aforementioned patent document still presents the following problems in actual use: Currently available smoke and fire prevention regulating valves, due to unreliable connections between pipes and ducts, are prone to instability, causing shaking, breakage, and damage. This makes it difficult to meet the connection requirements of workers. Furthermore, because smoke needs to be filtered, the filter plate disassembly method is cumbersome, resulting in low efficiency in filter plate disassembly.

Detailed Implementation
[0028] The present invention will be further described below with reference to the embodiments.
[0029] Please see Figure 1-6 This utility model provides a novel smoke and fire prevention regulating valve, including a pipe body 1 and a base 2. The base 2 is fixed to the inner side wall of the pipe body 1. Two symmetrically distributed valve stems 3 are rotatably connected to one side wall of the base 2. Valve blades 4 are tightly sleeved on the outer surface of the valve stems 3. An actuator 5 is fixed to one side wall of the pipe body 1 and is coaxially fixed to one of the valve stems 3. Two hinge seats 6 are fixed to one side wall of the two valve blades 4. A transmission rod 7 is hinged to one side wall of the two hinge seats 6. A filter plate 8 is provided on one side of the pipe body 1. A disassembly and assembly assembly 9 adapted to the pipe body 1 is provided on one side of the filter plate 8. A temperature fuse 10 is fixed to the inner side wall of the pipe body 1 and is adapted to the actuator 5.
[0030] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, it is worth noting that the disassembly and assembly component 9 includes a through groove 91, which is formed on one side wall of the pipe body 1. The filter plate 8 is slidably connected to the through groove 91. A connecting plate 92 is fixed to one side wall of the filter plate 8. An operating rod 93 is rotatably connected to the top side wall of the connecting plate 92. A transmission wheel 94 is fastened to the outer surface of the operating rod 93. A rotating wheel 95 is fixed to one end of the operating rod 93. Two mounting blocks 96 are symmetrically distributed and fixed to the top side wall of the connecting plate 92. One side wall of each mounting block 96 slides through it. A limiting rod 97 is provided, and a connecting rod 98 is hinged between the limiting rod 97 and the transmission wheel 94. A ring body 99 is sleeved on the outer surface of the limiting rod 97, and a spring 910 is sleeved on the outer surface of the limiting rod 97. One end of the spring 910 is fixed to one side wall of the ring body 99, and the other end of the spring 910 is fixed to one side wall of the mounting block 96. Two mounting plates 911 are symmetrically distributed and fixed to the outer side wall of the pipe body 1. A limiting hole 912 is opened on one side wall of the mounting plate 911, and the limiting rod 97 is adapted to the limiting hole 912.
[0031] It should be noted that the disassembly and assembly component 9 allows for the quick disassembly and installation of the filter plate 8, facilitating the disassembly and cleaning of the filter plate 8 by staff. Furthermore, in conjunction with the filter plate 8, it can filter the smoke inside the pipe body 1, thereby preventing the smoke impurities inside the pipe body 1 from causing harm to people escaping during a fire. The disassembly method is simple and highly flexible.
[0032] Further as Figure 2 , Figure 5 and Figure 6 As shown, it is worth noting that a clamping assembly 11 is provided on the outside of the pipe body 1. The clamping assembly 11 includes multiple mounting seats 111. The multiple mounting seats 111 are symmetrically distributed and fixed to the outer side wall of the pipe body 1. A bracket 112 is hinged to one side wall of the mounting seat 111. A threaded hole 113 is opened on one side wall of the bracket 112. A screw 114 is threadedly connected to the threaded hole 113. A rubber ring 115 is fixed to one end of the screw 114, and a knob 116 is fixed to the other end of the screw 114.
[0033] It should be noted that by setting the clamping component 11, the stability of the connection between the pipe body 1 and the air duct can be improved, effectively preventing the connection from shaking and causing breakage and damage. It provides strong protection for the connection between the pipe body 1 and the air duct, and the structure is easy to operate and highly practical.
[0034] This solution has the following working process: When the technician uses this device, when the temperature inside the pipe body 1 exceeds the preset value of the temperature fuse 10, a control command is sent to the actuator 5. The actuator 5 drives one of the valve stems 3 to rotate. Utilizing the transmission action between the transmission rods 7, the two valve blades 4 rotate synchronously, causing the two valve blades 4 to close, achieving the purpose of fire isolation inside the pipe body 1. When the pipe body 1 needs to be connected and installed with the air duct, it is initially fixed using bolts. By flipping the bracket 112 and rotating the knob 116, the screw 114... The screw 114 rotates synchronously, and the transmission between the screw 114 and the threaded hole 113 causes the screw 114 to move spirally after being subjected to force, thereby driving the pressure ring to move synchronously. The pressure ring presses and positions the air duct and the pipe body 1. When the filter plate 8 needs to be disassembled and cleaned, the rotating wheel 95 is rotated, causing the operating rod 93 to rotate synchronously, which drives the transmission wheel 94 to rotate synchronously. The transmission of the connecting rod 98 causes the limiting rod 97 to move until the limiting rod 97 separates from the limiting hole 912, thereby releasing the limiting state of the filter plate 8, and the filter plate 8 can be disassembled and cleaned.
[0035] As can be seen from the above working process, the disassembly and assembly component 9 enables the quick disassembly and installation of the filter plate 8, facilitating the disassembly and cleaning of the filter plate 8 by staff. Furthermore, in conjunction with the filter plate 8, it filters the smoke inside the duct body 1, thereby preventing smoke impurities from harming people escaping during a fire. The disassembly method is simple and highly flexible. The clamping component 11 enhances the stability of the connection between the duct body 1 and the ductwork, effectively preventing breakage due to shaking at the connection point. It provides strong protection for the connection between the duct body 1 and the ductwork, and its structure is convenient to operate and highly practical.
[0036] Further as Figure 1 and Figure 3 As shown, it is worth noting that the side of the bracket 112 closest to the mounting base 111 is a smooth arc surface, and the cross-section of the bracket 112 is L-shaped.
[0037] It should be noted that the bracket 112 not only prevents jamming when it is flipped, but also improves the stability of the bracket 112 when it is flipped.
[0038] Further as Figure 1 and Figure 6 As shown, it is worth noting that two symmetrically distributed baffles 12 are fixed to the top side wall of the base, and one side wall of the baffle 12 is fixed to the inner side wall of the pipe body 1.
[0039] It should be noted that by setting the baffle 12, the valve blade 4 is ensured to be in a horizontal and vertical state with the baffle 12, thereby effectively improving the isolation effect on flue gas.
[0040] Further as Figure 1 and Figure 6 As shown, it is worth noting that the valve blade 4 is in contact with one side of the baffle 12, the base 2 has a convex cross-section, and the angle between the base 2 and the baffle 12 is a right angle.
[0041] It should be noted that by setting the baffle 12, it is ensured that the valve blade 4 can be in a tight fit with the baffle 12 after closing, thereby improving the fireproof effect of smoke isolation.
[0042] In summary: The bracket 112 not only prevents jamming when it is rotated, but also improves its stability. The baffle 12 ensures that the valve blade 4 and the baffle 12 are in a horizontal and vertical position, thereby effectively improving the smoke isolation effect. Furthermore, the baffle 12 ensures that the valve blade 4 is in a tight fit with the baffle 12 after closing, thus improving the smoke isolation and fire prevention effect.
[0043] Actuator 5 can be purchased from the market. Actuator 5 is equipped with a power supply. It is a mature technology in the field and has been fully disclosed. Therefore, it will not be described again in the specification.
