Description

Technical Field

[0001] This invention relates to the field of regulating valve blade technology, and more specifically to a sealing structure for a tunnel regulating valve blade. Background Technology

[0002] In tunnel ventilation duct systems, the function of regulating valve blades is to ensure that they can be tightly closed when closed to prevent air leakage, or to provide ventilation and exhaust when open. With the continuous development of modern technology and people's increasing demands for indoor air temperature comfort, ventilation systems have become an indispensable part of buildings.

[0003] Current technology has shortcomings: The sealing structure of regulating valve blades usually uses soft materials such as rubber or plastic as sealing gaskets. However, these materials are prone to aging, deformation or wear during long-term use, which leads to a decrease in sealing performance and air leakage problems.

[0004] Because the air resistance during ventilation varies, the blades may wobble unbalancedly during ventilation. This unbalanced wobble can cause vibrations in the regulating valve system. These vibrations not only affect the quietness of the surrounding environment but may also be transmitted to connected ducts and other equipment, causing unnecessary noise in the entire air conditioning and ventilation system. At the same time, the unbalanced wobble of the blades can interfere with the regulating valve's precise control of the air volume, preventing the system from achieving the expected ventilation effect and thus affecting the comfort of the indoor environment.

[0031] The left side and the right side of the inner cavity of the ventilation box body 1 are fixedly connected with a supporting column 101, a circular ring movable clamping cover 102 and a first sealing strip 103.

[0032] The side of the first piston circular ring 4 is fixedly connected to the inner cavity side wall of the left circular ring movable clamping cover 102, one end of the movable shaft 207 is movably connected to the inner cavity side wall of the circular ring movable clamping cover 102, the other end is movably connected to the inner cavity side wall of the right circular ring movable clamping cover 102, and the second piston circular ring 5 is fixedly connected to the inner cavity side wall of the right circular ring movable clamping cover 102.

[0033] The working principle of the present application is that when the wind resistance is different, the first vane plate 2 and the second vane plate 3 start to shake and swing in the case of ventilation, the side of the first piston circular ring 4 is fixedly connected to the inner cavity side wall of the circular ring movable clamping cover 102, when the first vane plate 2 starts to overturn, because the first pushing circular ring 406 is fixed to the outer circle side wall of the movable shaft 207, the rotation of the movable shaft 207 will drive the first pushing circular ring 406, since the first cavity 401 and the third cavity 403 are sealed cavities, the internal gas pressure of the first cavity 401 is less than that of the third cavity 403, the internal gas pressure of the first cavity 401 is less than the resistance of the spring 408, and the resistance of the spring 408 is less than the internal gas pressure of the third cavity 403, when the first pushing circular ring 406 is subjected to small amplitude rotation of the first vane plate 2, it starts to rotate around the movable shaft 207 as the center, and pushes the first piston sliding block 405 to slide in the first cavity 401, when the wind resistance in the ventilation pipeline gradually stabilizes, the internal gas pressure of the first cavity 401 will rebound to make the first piston sliding block 405 return to the initial position, keeping the first vane plate 2 stable, and the second vane plate 3 is the same.

[0034] When the wind resistance in the ventilation duct is too large, the first leaf plate 2 rotates greatly and starts to push the first push ring 406, the first piston sliding block 405 slides in the first cavity 401, and the second piston sliding block 407 also starts to move and will be in contact with the limiting block 412 after being limited. At this time, the third piston sliding block 409 will be affected by the resistance of the spring 408 and start to slide in the third cavity 403. The air in the third cavity 403 will be transmitted to the inner cavity of the second piston ring 5 through the hollow hose 411, and the air in the fourth cavity 501 will be affected by the resistance of the fourth piston sliding block 502 in the fourth cavity 501. The second push ring 503 connected to the side of the fourth piston sliding block 502 drives the push block 504 to move in a ring shape. Because the second piston ring 5 is fixed in the other side of the ring-shaped movable cover 102, the push block 504 and the top block 208 are in the same position of ring-shaped movement, so at this time the top block 208 on the side of the first leaf plate 2 will be pushed by the push block 504 to rotate in a circle and contact the top block 208. When the wind resistance in the ventilation duct returns to normal, the push block 504 pushes the top block 208 to return to a certain angle, the third piston sliding block 409 returns to the initial position, the spring 408 starts to rebound and pushes the second piston sliding block 407, so that the air pressure in the first cavity 401 pushes the first piston sliding block 405, and finally the first leaf plate 2 returns to normal. The same is true for the second leaf plate 3.

[0035] When the wind resistance in the ventilation duct is too large, the first leaf plate 2 rotates greatly and starts to push the first push ring 406, the first piston sliding block 405 slides in the first cavity 401, and the second piston sliding block 407 also starts to move and will be in contact with the limiting block 412 after being limited. At this time, the third piston sliding block 409 will be affected by the resistance of the spring 408 and start to slide in the third cavity 403. The air in the third cavity 403 will be transmitted to the inner cavity of the second piston ring 5 through the hollow hose 411, and the air in the fourth cavity 501 will be affected by the resistance of the fourth piston sliding block 502 in the fourth cavity 501. The second push ring 503 connected to the side of the fourth piston sliding block 502 drives the push block 504 to move in a ring shape. Because the second piston ring 5 is fixed in the other side of the ring-shaped movable cover 102, the push block 504 and the top block 208 are in the same position of ring-shaped movement, so at this time the top block 208 on the side of the first leaf plate 2 will be pushed by the push block 504 to rotate in a circle and contact the top block 208. When the wind resistance in the ventilation duct returns to normal, the push block 504 pushes the top block 208 to return to a certain angle, the third piston sliding block 409 returns to the initial position, the spring 408 starts to rebound and pushes the second piston sliding block 407, so that the air pressure in the first cavity 401 pushes the first piston sliding block 405, and finally the first leaf plate 2 returns to normal. The same is true for the second leaf plate 3.

[0036] When the first leaf plate 2 and the second leaf plate 3 are closed and sealed, the positions of the sealing strips fixed on the sides of the first leaf plate 2 and the second leaf plate 3 are opposite to each other. The closure will be in close contact with the first sealing strip 103 on the side wall of the ventilation box 1, and the tenth sealing strip 305 fixed on the second leaf plate 3 will be in close contact with the clamping groove 206 on the first leaf plate 2. The side of the tenth sealing strip 305 is in close contact with the side of the fifth sealing strip 205, and the clamping state is achieved, so as to achieve better sealing state.

[0037] The above description is only a preferred embodiment of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
