[0022] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0025] The embodiment of the present application solves the technical problem of uneven airflow distribution inside the valve in the prior art by providing a ventilation duct valve.

[0026] The technical solution in the embodiments of the present application is to solve the above technical problems, and the overall idea is as follows:

[0027] like Figure 1-Figure 4 As shown, the present application provides a ventilation duct valve, comprising: a valve body 1, a valve plate 2 is arranged in the valve body 1, the valve plate 2 can rotate radially in the valve body 1, the upstream end of the valve body 1 is connected to an adjustment tube 3, specifically, the adjustment tube 3 is threadedly connected to the end of the valve body 1, an air guide plate 4 is arranged in the adjustment tube 3, the air guide plate 4 is arranged parallel to the valve plate 2 in the open state, the side surface of the air guide plate 4 is an arc surface, and the thickness of the air inlet end of the air guide plate 4 is less than the thickness of its air outlet end.

[0028] When the valve plate 2 of the valve is opened, the air guide plate 4 is on the same plane as the valve plate 2, and the thickness of the air inlet end of the air guide plate 4 is smaller than the thickness of the air outlet end, so that the air flow can be adjusted by the air guide plate 4 to avoid the valve plate 2, reduce the collision between the air flow and the valve plate 2, and thus reduce the resistance and the noise.

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] The thickness of the air inlet end of the air deflector 4 is at most one-tenth the diameter of the adjustment tube 3, and the thickness of the air outlet end of the air deflector 4 is greater than the thickness of the valve plate 2. In this embodiment, the diameter of the adjustment tube 3 is 500 mm, the thickness of the air inlet end of the air deflector 4 is set to at most 50 mm, and the thickness of the air outlet end of the air deflector 4 is greater than the thickness of the valve plate 2. This can block the valve plate 2, allowing the airflow to be separated by the air deflector 4, and reducing the airflow blocking effect of the valve plate 2, thereby reducing wind noise.

[0031] The material of the air guide plate 4 is aluminum alloy or stainless steel to reduce friction resistance and extend service life.

[0032] Preferably, Figure 3-Figure 6 As shown, a mounting ring 5 is fixedly provided inside the adjustment tube 3, and a retaining ring 6 is fixedly provided at the air inlet end of the air guide plate 4. Of course, in order to make the air guide plate 4 more stable, a retaining ring 6 can also be fixedly provided at the middle position of the air guide plate 4. The air guide plate 4 can be operably passed through the mounting ring 5 and the retaining ring 6 is matched on the mounting ring 5. First, the adjustment tube 3 is screwed on the end of the valve body 1, and then the air guide plate 4 is inserted into the adjustment tube 3. The angle of the air guide plate 4 is adjusted so that the air guide plate 4 is parallel to the open state of the valve plate 2. Finally, the retaining ring 6 is installed on the mounting ring 5, thereby realizing the accurate installation of the air guide plate 4.

[0033] Furthermore, the contact surface between the mounting ring 5 and the retaining ring 6 is a plane, and the end surface of the retaining ring 6 facing away from the mounting ring 5 contacts the arc surface of the inner wall of the adjustment tube 3, so that the airflow in the adjustment tube 3 can be guided more smoothly, avoiding the disturbance of the airflow by the mounting ring 5 and reducing wind noise.

[0034] The end surface of the mounting ring 5 facing the retaining ring 6 is provided with a plurality of positioning grooves 7, and the end surface of the retaining ring 6 facing the mounting ring 5 is provided with a positioning block 8, which can be operably inserted into the positioning groove 7. Specifically, the positioning grooves 7 are evenly distributed on the end surface of the mounting ring 5, and at least one positioning block 8 is provided. The end surface of the mounting ring 5 is provided with a buffer layer 9, which is specifically a rubber ring. Figure 6 .

[0035] During the installation of the air guide plate 4, the air guide plate 4 is first adjusted to a fixed angle, and then the positioning block 8 is clamped in the corresponding positioning groove 7 to achieve precise positioning to avoid rotation during use. Between the mounting ring 5 and the retaining ring 6, a buffer layer 9 is used for shock absorption to avoid unstable airflow causing collision between the mounting ring 5 and the retaining ring 6 to generate noise. Specifically, the positioning block 8 can be one, two relatively set, or multiple staggered. Of course, the more positioning blocks 8 there are, the more stable the fit between the mounting ring 5 and the retaining ring 6.

[0036] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0037] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
