These valves are mainly made of fiberglass reinforced plastic, which has extremely high strength and corrosion resistance. Fiberglass air valves are widely used in industrial plants and civil buildings. They are key components in air conditioning and ventilation system ducts, which can regulate the air volume of branch pipes. By adjusting the opening of the air valve, the airflow can be controlled to meet the ventilation needs of different environments.

[0003] The blades inside the FRP molded air valve are mostly tilting type. If the air pressure inside the pipeline is too high, it is not convenient to tilt the blades for adjustment because the surface pressure of the blades is too high.

[0004] Therefore, a fiberglass molded air valve with an improved structure is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a fiberglass molded air valve with an improved structure to solve the problem mentioned in the background art that the internal blades of the fiberglass molded air valve are not easy to adjust under high pressure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fiberglass molded air valve with an improved structure, comprising an adjusting pipe and a flange. The top and bottom ends of the adjusting pipe are both fixed with flanges. An interleaved airflow adjusting assembly is provided at the bottom end inside the adjusting pipe. The interleaved airflow adjusting assembly includes a guide platform, an adjusting platform, a slide groove, a first air duct, a side platform, a rotating platform, a rotating shaft, a handwheel, a screw, a guide rod, a screw hole, an inner plate, and a second air duct. The guide platform is installed at the bottom end inside the adjusting pipe, and the adjusting platform is installed on the left side below the guide platform. A slide groove is provided inside the adjusting platform. The adjustment platform has a first air groove on its top and bottom surfaces. A side platform is fixed to the bottom left side of the adjustment pipe. A rotating platform is fixed to the left side of the side platform. A rotating shaft is movably installed inside the rotating platform. A handwheel is installed on the left side of the rotating shaft. The right side of the rotating shaft extends into the side platform. A screw is fixed to the right side of the rotating shaft. A guide rod is movably installed inside the side platform. A screw hole is provided inside the guide rod. The right side of the screw extends into the screw hole. An inner plate is installed on the right side of the guide rod. The right side of the inner plate extends into the slide groove. A second air groove is provided through the top of the inner plate.

[0007] As a further technical solution of this utility model, a plurality of the first air ducts are provided on the surfaces of the top and bottom ends of the adjustment platform, and the plurality of the first air ducts are symmetrically distributed.

[0008] As a further technical solution of this utility model, the surface of the screw is provided with external threads, and the inside of the screw hole is provided with internal threads.

[0009] As a further technical solution of this utility model, several second air ducts are provided through the top surface of the inner plate, and the several second air ducts are distributed at equal intervals.

[0010] As a further technical solution of this utility model, an observation window is provided on the surface of the top of the side platform, and a transparent plate is installed inside the observation window.

[0011] As a further technical solution of this utility model, a positioning platform is fixed at the top of the inside of the adjusting tube, a ball is movably installed inside the positioning platform, and an auxiliary groove is provided on the outer wall of the ball.

[0012] As a further technical solution of this utility model, a plurality of auxiliary grooves are provided on the outer side wall of the rolling ball, and the plurality of auxiliary grooves are arranged in a ring.

[0013] As a further technical solution of this utility model, a soundproof cover is installed on the outer wall of the regulating tube, and an inner cavity is provided inside the soundproof cover, and a soundproof felt is installed inside the inner cavity.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting an adjustment platform and an inner plate, the inner plate is inserted into the slide groove inside the adjustment platform. The first air groove on each side is connected to the second air groove, which can keep the internal channel of the adjustment pipe unobstructed. When the screw is driven to rotate by rotating the shaft with the handwheel, the screw is threaded with the screw hole. As the guide rod moves to the right along the inside of the side platform, it can push the inner plate to move slowly to the right along the inside of the slide groove. During this process, the first air groove and the second air groove are intersected, and the channel formed gradually becomes smaller until they are completely misaligned, closing the internal channel of the adjustment pipe. In this way, the air volume of the pipeline is adjusted, realizing the intersecting flow regulation function inside the FRP molded air valve.

[0016] 2. By setting a ball, the ball is movably installed at the air inlet position inside the regulating pipe with the assistance of the positioning table. When the airflow enters the regulating pipe, it first contacts the auxiliary groove. When the airflow is small, the airflow can flow along the auxiliary groove and the gap between the regulating pipe and the ball. If the airflow is large, the pressure applied to the surface of the ball is large. At this time, the ball can be pushed to roll. During this process, the flow velocity and pressure of the airflow can be reduced, thus realizing the auxiliary buffer and pressure relief function inside the FRP molded air valve.

[0017] 3. By setting a soundproof cover, which is placed on the outside of the regulating pipe and the inner cavity is lined with soundproof felt, the soundproof felt can help block the noise transmitted from inside the regulating pipe to the outside, thus enhancing the noise reduction effect of the fiberglass molded air valve during use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4This utility model provides an embodiment of a fiberglass molded air valve with an improved structure, comprising an adjusting pipe 1 and a flange 2. The flange 2 is fixed to both the top and bottom ends of the adjusting pipe 1. An interlaced airflow regulating assembly is provided at the bottom end inside the adjusting pipe 1. The interlaced airflow regulating assembly includes a guide platform 3, an adjusting platform 4, a slide 5, a first air duct 6, a side platform 7, a rotating platform 8, a rotating shaft 9, a handwheel 10, a screw 11, a guide rod 12, a screw hole 13, an inner plate 14, and a second air duct 15. The guide platform 3 is installed at the bottom end inside the adjusting pipe 1, and the adjusting platform 4 is installed on the left side below the guide platform 3. The adjusting platform 4 has a slide 5 inside, and the surfaces of the top and bottom ends of the adjusting platform 4 are provided with first air ducts 6. Several first air ducts 6 are provided on the surfaces of the top and bottom ends of the adjusting platform 4, and the several first air ducts 6 are symmetrically distributed. The bottom end of the left side of the adjusting pipe 1 is fixed... There is a side platform 7, and a rotating platform 8 is fixed to the left side of the side platform 7. A rotating shaft 9 is movably installed inside the rotating platform 8. A handwheel 10 is installed on the left side of the rotating shaft 9. The right side of the rotating shaft 9 extends into the interior of the side platform 7. A screw 11 is fixed to the right side of the rotating shaft 9. A guide rod 12 is movably installed inside the side platform 7. A screw hole 13 is provided inside the guide rod 12. The right side of the screw 11 extends into the interior of the screw hole 13. The surface of the screw 11 is provided with external threads. The inside of the screw hole 13 is provided with internal threads. An inner plate 14 is installed on the right side of the guide rod 12. The right side of the inner plate 14 extends into the interior of the slide groove 5. A second air duct 15 is provided through the top of the inner plate 14. Several second air ducts 15 are provided through the top surface of the inner plate 14. The several second air ducts 15 are distributed at equal intervals. An observation window 16 is provided on the top surface of the side platform 7. A transparent plate 17 is installed inside the observation window 16.

[0025] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during use, the second air duct 15 connects with the first air duct 6 to form a channel for airflow. When the handwheel 10 drives the rotating shaft 9 to rotate the screw 11, the screw 11 and the screw hole 13 are threaded together, which drives the guide rod 12 to push the inner plate 14 to the left along the sliding groove 5 inside the adjustment platform 4. During this process, the second air duct 15 and the first air duct 6 gradually intersect, and the channel formed gradually becomes smaller until the channel is closed. With the help of the observation window 16 on the surface of the side platform 7, the position of the guide rod 12 inside the side platform 7 can be observed to indirectly determine the size of the channel opening.

[0026] A positioning platform 18 is fixed at the top of the inside of the regulating pipe 1. A ball 19 is movably installed inside the positioning platform 18. An auxiliary groove 20 is provided on the outer side wall of the ball 19. Several auxiliary grooves 20 are provided on the outer side wall of the ball 19, and the several auxiliary grooves 20 are distributed in a ring.

[0027] Specifically, such as Figure 1 and Figure 4As shown, when in use, after the airflow enters the regulating tube 1, it first contacts and collides with the ball 19 at the open end. When the airflow is large, the impact force can push the ball 19 to roll, thereby helping to slow down the airflow speed.

[0028] A soundproof cover 21 is installed on the outer wall of the regulating pipe 1. The soundproof cover 21 has an inner cavity 22, and a soundproof felt 23 is installed inside the inner cavity 22.

[0029] Specifically, such as Figure 1 and Figure 4 As shown, when in use, a sound insulation felt 23 is laid in the inner cavity 22 inside the sound insulation cover 21 and is located on the outside of the regulating pipe 1. When noise inside the regulating pipe 1 is transmitted to the outside, the sound insulation felt 23 can help to absorb and block the noise to a certain extent, thereby reducing the impact of noise on the surroundings.

[0030] Working principle: When the airflow enters the regulating pipe 1, it first contacts the ball 19 at the open end. With the assistance of the positioning table 18, the ball 19 is movably installed at the open end of the regulating pipe 1. When the airflow is small, it can flow through the auxiliary groove 20 or the gap between the regulating pipe 1 and the ball 19. Conversely, when the airflow is large, it impacts the ball 19, causing it to roll. During this process, the airflow is buffered and its speed is reduced. After passing through the ball 19, the airflow can be discharged through the passage formed by the first air groove 6 and the second air groove 15. If the outer handwheel 10 is turned, the drive shaft 9 drives the screw 11 to rotate. During the process, the screw 11 and the screw hole 13 are threaded together, which can drive the guide rod 12 to push the inner plate 14 to move to the left along the slide groove 5 inside the adjustment platform 4. During this process, the second air groove 15 and the first air groove 6 gradually intersect, and the channel formed gradually becomes smaller until the channel is closed. With the help of the observation window 16 on the surface of the side platform 7, the position of the guide rod 12 inside the side platform 7 can be observed, and the size of the channel opening can be indirectly judged. A soundproof cover 21 is installed on the outside of the adjustment pipe 1, and a soundproof felt 23 is laid in the inner cavity 22. The soundproof felt 23 can help absorb and block the noise transmitted from the inside of the adjustment pipe 1 to a certain extent, thereby reducing the impact of noise on the surroundings.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
