Description

Technical Field

[0001] This utility model relates to the field of fire valve design, and more particularly to a fire valve for an air purification system valve. Background Technology

[0002] A fire damper is a movable sealing device used to prevent fire in pipelines. It is usually in the open state, but when the temperature inside the pipeline reaches a preset value, the fire damper will automatically close, thereby cutting off the connection between the indoor and outdoor areas and preventing the fire from spreading.

[0003] Fire dampers are widely used in various situations where fire spread needs to be prevented, such as when installed at the end of air purification system ducts to provide further protection for their safety. Currently, after a fire damper is triggered, it needs to be reset for reuse. During the reset process, the handle needs to be turned to reopen the blades and reconnect the valve port to the inside and outside. Resetting requires a lot of force, which is difficult for female users to operate, thus causing some trouble and limiting its functionality. Utility Model Content

[0021] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0022] In the description of this utility model, it should be noted that the orientations or positional relationships indicated by terms such as "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end" are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description.

In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] A preferred embodiment of the fireproof valve in an air purification system valve provided by this utility model is, for example... Figures 1 to 4 As shown: A fireproof valve for an air purification system includes a housing 1, a valve port 3 is provided inside the housing 1, a support assembly 4 is fixedly provided at the top of the valve port 3, a blade 2 is rotatably provided between the top and bottom of the inner wall of the valve port 3, the blade 2 is rotatably connected to the support assembly 4, and a rocking assembly 5 is fixedly provided on one side of the top of the valve port 3.

[0025] In this embodiment, the rocking component 5 includes a connecting plate 501. Two support seats 502 are symmetrically fixedly connected to both ends of one side of the connecting plate 501. A threaded rod 509 is rotatably connected between the top ends of the two support seats 502. A guide block 504 is threaded through and threadedly connected to the outer wall of the threaded rod 509. A connecting rod 505 is rotatably connected to the top end of the guide block 504. A slot 508 is opened at the end of the connecting rod 505 away from the guide block 504. A crank handle 503 is fixedly provided at one end of the threaded rod 509.

[0026] With the above solution, by turning the rocker handle 503, the two ends of the threaded rod 509 are driven to rotate between the two support seats 502, thereby driving the guide block 504 to move along the threaded rod 509, so that one end of the connecting rod 505 rotates relative to the guide block 504. Since the end of the connecting rod 505 away from the guide block 504 is connected to the connecting assembly 408 through the slot 508, the handle 407 rotates around the reference axis of the rotating rod 406, and the handle 407 is reset. Compared with directly pulling the handle 407, turning the rocker handle 503 can achieve the purpose of saving effort.

[0027] In this embodiment, a protruding rod 506 is fixedly connected to one side of the connecting rod 505, and a stabilizing kit 507 is slidably connected to the outer wall of the protruding rod 506. The bottom outer wall of the stabilizing kit 507 is slidably connected to one end of the guide block 504.

[0028] With the above scheme, when the guide block 504 moves along the threaded rod 509, the protruding rod 506 slides on the inner wall of the top of the stabilizing kit 507, and its bottom end slides up and down along one side of the guide block 504, which can distribute part of the force on the connecting rod 505 and prevent it from breaking due to excessive thrust.

[0029] In this embodiment, the support assembly 4 includes a support body 401, which is fixedly connected to the top of the housing 1. A support block 404 is fixedly provided at the top of the support body 401. A rotating rod 406 is rotatably connected through one side of the support block 404. The rotating rod 406 is rotatably connected to the inside of the support body 401. A handle 407 is fixedly sleeved at the top of the rotating rod 406. A connecting component 408 is fixedly provided at the end of the handle 407 away from the rotating rod 406.

[0030] Through the above scheme, the guide block 504 drives the connecting rod 505 to generate thrust, causing the handle 407 to rotate, thereby causing the rotating rod 406 to rotate, driving the entire blade 2 to rotate, and resetting the valve port 3 from the sealed state to the initial open state.

[0031] In this embodiment, a pointer 403 is fixedly provided on one side of the bottom end of the rotating rod 406, and a scale 402 is fixedly provided on the top end of the support body 401, with the scale 402 located below the pointer 403.

[0032] With the above scheme, when the pointer 403 points to the front end of the device, the scale 402 displays 0 degrees, that is, at this time the blade 2 closes the valve port 3, and the fire source on one side of the connection between the housing 1 and the air purification pipe is isolated from the outside, thus achieving the purpose of fire prevention. When the pointer 403 rotates 90 degrees along the scale 402, it means that the valve port 3 is open, which means that the reset is successful.

[0033] In this embodiment, a reset valve 405 is fixedly provided on one side of the top end of the support body 401.

[0034] With the above solution, when a fire occurs, the reset valve 405 will trip. At this time, the handle 407 cannot rotate the lever 406, which ensures that after the valve port 3 is closed, the blade 2 will not rotate due to external factors, causing the valve port 3 to open and lose its fireproof effect. When it is necessary to reset the blade 2, manually pull the reset valve 405 to its original position, and then the device can be quickly reset to its initial working state.

[0035] In this embodiment, the connecting component 408 includes a pull block 4081, a locking rod 4082 fixedly provided on one side of the pull block 4081, a clamping shell 4084 rotatably connected through the outer wall of the locking rod 4082, the outer wall of the locking rod 4082 rotatably connected to the inner wall of the slot 508, a connecting rod 505 located between the inner walls of the clamping shell 4084, a sleeve 4085 fixedly provided on one side of the clamping shell 4084, a spring 4083 fixedly connected between the bottom of the inner wall of the sleeve 4085 and one side of the pull block 4081, and the spring 4083 sleeved on the outer wall of the locking rod 4082.

[0036] With the above scheme, in the initial normal working state, the connecting rod 505 is separated from the connecting component 408 and the two are not connected. When the fire is extinguished and the handle 407 needs to be pulled to reset the device, the pull block 4081 is moved so that the end of the locking rod 4082 away from the pull block 4081 enters the sleeve 4085. At this time, the spring 4083 is stretched, aligning the slot 508 of the connecting rod 505 with the through-holes on both sides of the clamping shell 4084. Then the pull block 4081 is released so that the locking rod 4082 passes through the slot 508 and both sides of the clamping shell 4084, thus achieving the function of connecting the connecting rod 505 and the connecting component 408. Then, the handle 407 is rotated using the support component 4 to reset the device.

[0037] In this embodiment, the rocking component 5 is fixedly connected to the housing 1 by a connecting plate 6 through several bolts.

[0038] The above solution is used to stabilize and connect the housing 1 and the rocking assembly 5. At the same time, the rocking assembly 5 can be quickly disassembled and assembled by turning several screws in the connecting plate 6.

[0039] Working principle: When operating and using this utility model, as follows... Figures 1 to 4As shown, during use, the rear end of this device is connected to the air purification duct. Under normal conditions, the blade 2 is parallel to both sides of the inner wall of the valve port 3, and the valve port 3 is in the connected state, connecting the air purification system duct to the outside. At this time, the reset valve 405 is in the initial state, and the pointer 403 points to 90 degrees on the scale 402.

[0040] When a fire occurs, the temperature sensor inside the support body 401 senses the temperature change through electronic components such as thermistors inside the support body 401. When the temperature reaches the set value, it sends an electrical signal to the actuator, which controls the rotating rod 406 to quickly drive the blade 2 to rotate and seal the valve port 3. The reset valve 405 opens, ensuring that the blade 2 will not rotate due to external factors after the valve port 3 is closed. At this time, the pointer 403 points to the 0 degree mark on the scale 402.

[0041] After resolving the fire issue, the device needs to be reset for reuse. At this time, move the pull block 4081 to allow the end of the locking rod 4082 away from the pull block 4081 to enter the sleeve 4085. This stretches the spring 4083, aligning the slot 508 of the connecting rod 505 with the through-holes on both sides of the clamping housing 4084. Then release the pull block 4081, allowing the locking rod 4082 to pass through the slot 508 and both sides of the clamping housing 4084, connecting the connecting rod 505 to the connecting assembly 408. Then return the reset valve 405 to its original position and turn the crank handle 503. The two ends of the moving threaded rod 509 rotate between the two support seats 502, thereby driving the guide block 504 to move along the threaded rod 509, causing one end of the connecting rod 505 to rotate relative to the guide block 504. Since the end of the connecting rod 505 away from the guide block 504 is connected to the connecting assembly 408 through the slot 508, the handle 407 rotates around the reference axis of the rotating rod 406, resetting the handle 407. At this time, the pointer 403 points to 90 degrees of the scale 402 again, and the blade 2 is parallel to both sides of the inner wall of the valve port 3 again, completing the reset of the device.

[0042] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
