[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 9The utility model provides a technical solution: a low-noise sealed air volume regulating valve for ships, comprising a regulating component 1, a gear box 2 is arranged under the regulating component 1, and a sleeve 3 is arranged inside the gear box 2, a control handle 6 is rotatably connected inside the sleeve 3, and a limit component 4 is arranged outside the control handle 6, the limit component 4 comprises a fixed ring 401, and a push rod 402 is fixedly connected to the fixed ring 401, a guide groove 403 is opened in the sleeve 3, a groove 404 is opened on one side of the guide groove 403, and a limit rod 405 is slidably connected in the groove 404, a return spring 406 is connected to the outer surface of the limit rod 405, and one end of the return spring 406 is fixedly connected to the inner wall of the groove 404, and the control handle 6 is provided with a limit groove 407, and the control handle 6 is provided with a threaded groove 408, and the threaded groove 408 is provided below the limit groove 407. By setting the limit rod 405 and the limit groove 407, when the limit rod 405 is engaged with the limit groove 407, the control handle 6 is limited to prevent the control handle 6 from continuously rotating. The limit groove 407 is in the shape of a long strip to ensure that the limit rod 405 is engaged with the limit groove 407, and one side of the limit rod 405 is an inclined surface, so as to facilitate the release of the limit on the control handle 6. By setting the reset spring 406, when the elasticity of the reset spring 406 is restored, the limit rod 405 is pushed to reset, and the limit on the control handle 6 is released.

[0028] A number of limit grooves 407 are sequentially arranged along the outer wall of the control handle 6, and the limit grooves 407 are engaged with the limit rod 405, the fixed ring 401 is threadedly connected to the control handle 6 via the thread groove 408, the push rod 402 is slidably connected to the guide groove 403, and two push rods 402 are symmetrically arranged along the center of the fixed ring 401. By setting the thread groove 408 and the fixed ring 401, the fixed ring 401 can be moved along the direction of the push rod 402 by rotating the control handle 6, and by setting the guide groove 403 and the push rod 402, the fixed ring 401 is limited to prevent the fixed ring 401 from rotating together with the control handle 6.

[0029] The regulating component 1 also includes an air volume regulating valve body 101, and a baffle 102 is overlapped inside the air volume regulating valve body 101. Two baffles 102 are symmetrically arranged along the center of the air volume regulating valve body 101. A transmission shaft 103 is fixedly connected under the baffle 102, and the transmission shaft 103 is rotatably connected to the air volume regulating valve body 101. By setting the transmission shaft 103, the rotation of the transmission shaft 103 drives the rotation of the baffle 102, thereby facilitating the adjustment of the angle of the baffle 102, thereby facilitating the adjustment of the air volume regulating valve body 101.

[0030] A transmission gear 104 is fixedly connected to the transmission shaft 103, and a transmission gear 2 105 is meshedly connected to one side of the transmission gear 104. The transmission gear 2 105 is rotationally connected to the gear box 2, and the gear box 2 is fixedly connected to the air volume regulating valve body 101. By setting a control handle 6 and a transmission gear 2 105, the control handle 6 is rotated to drive the rotation of the transmission gear 2 105. By setting the transmission gear 104 and the transmission gear 2 105, it is convenient to drive the transmission of power.

[0031] The transmission gear 2 105 is fixedly connected to the control handle 6 at the bottom, and the control handle 6 is rotationally connected to the gear box 2 through the sleeve 3.

[0032] A sealing assembly 5 is disposed outside the baffle 102, and the sealing assembly 5 includes a limiting column 501, and the limiting column 501 is in a T-shape.

[0033] A sealing rubber pad 502 is bonded to one side of the limiting column 501, and a sealing airbag 503 is overlapped on the back of the sealing rubber pad 502. The baffle 102 is snap-fitted and connected to the limiting column 504, and a rubber pad is bonded to the back of the limiting column 504. By setting the limiting column 101 and the limiting column 504, when the baffle 102 is snap-fitted with the limiting column 101 and the limiting column 2, the baffle 102 is limited. By setting the sealing rubber pad 502 and the sealing airbag 503, when the baffle 102 is snap-fitted with the limiting column 101, the sealing airbag 503 is squeezed, so that the sealing airbag 503 is expanded to fill the gap between the baffle 102 and the limiting column 501, thereby achieving a sealing effect.

[0034] Working principle: when using the air volume regulating valve, firstly, the control handle 6 is rotated to drive the transmission gear 2 105 to rotate, so that the transmission gear 2 105 drives the transmission gear 1 104 to rotate, and the transmission shaft 103 is driven to rotate through the transmission gear 104, thereby driving the baffle 102 to rotate along the center of the transmission shaft 103. When the control handle 6 is rotated, the control handle 6 is rotated to make the fixed ring 401 move through the threaded groove 408 provided on the outside of the control handle 6, so that the fixed ring 401 moves along the direction of the guide groove 403, pushing the push rod 402 to move along the guide groove 403, and at the same time, the push rod 402 pushes the limit rod 405 to move along the groove 404, thereby pushing the limit rod 405 and the limit rod 405 to move. The positioning groove 407 is engaged, thereby limiting the control handle 6 and preventing the control handle 6 from continuously rotating, thereby ensuring the service life of the regulating valve and completing the use of the air volume regulating valve; when the air volume regulating valve is sealed, first, the control handle 6 is rotated to make the transmission gear 2 105 drive the transmission gear 1 104 to rotate, and the transmission gear 1 104 drives the transmission shaft 103 to rotate. Through the rotation of the transmission shaft 103, the angle of the baffle 102 is adjusted so that the baffle 102 is engaged with the limiting column 1 501. At the same time, the sealing airbag 503 is pressurized so that the sealing airbag 503 squeezes the gap between the limiting column and the baffle 102 and the sealing rubber pad 502, thereby increasing the sealing effect.

[0035] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
