[0028] 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.

[0029] Reference Figure 1-Figure 3 The utility model provides an embodiment: an electrostatic glass fiber reinforced plastic air valve with an automatic reset function, comprising a shell 1, both ends of the shell 1 are through-shaped, the shell 1 is made of electrostatic glass fiber reinforced plastic, has the characteristics of corrosion resistance, high temperature resistance, wear resistance, etc., and is suitable for use in various harsh environments. A windshield 2 is arranged inside the shell 1, and the windshield 2 is arranged in a circular shape as a whole. A motor 3 is fixedly connected to the outer wall of the top of the shell 1, and the output shaft of the motor 3 is connected to the control mechanism 5 through the transmission mechanism 4;

[0030] Reference Figure 2 The transmission mechanism 4 includes a first bevel gear 41, the center of which is fixedly connected to the output shaft of the motor 3, and the bottom end of the first bevel gear 41 is meshed with a second bevel gear 42, and the bottom end of the second bevel gear 42 is rotatably connected to the top outer wall of the shell 1. The first bevel gear 41 can drive the second bevel gear 42 to rotate through the drive of the motor 3, thereby controlling the opening and closing of the wind shield 2 to achieve the effect of automatic reset.

[0031] Reference Figure 2-Figure 3The control mechanism 5 includes a rotating sleeve 51, which passes through and is rotatably connected to the top inner wall of the shell 1. The outer wall of the rotating sleeve 51 passes through and is fixedly connected to the inner wall of the second bevel gear 42. The second bevel gear 42 is driven by the motor 3 to rotate, so that the second bevel gear 42 can drive the rotating sleeve 51 to rotate. The bottom end of the rotating sleeve 51 is fixedly connected to the top center of the wind shield 2. The wind shield 2 can be driven to rotate by the rotation of the rotating sleeve 51 itself, thereby controlling the opening and closing of the entire valve. A long vertical groove 52 and a short vertical groove 57 are respectively provided on the outer wall of the rotating sleeve 51. The depth of the long vertical groove 52 is deeper than that of the short vertical groove 57. A control rod 54 is passed through and slidably connected to the inner wall of the rotating sleeve 51. A block 53 is fixedly connected to the outer wall of the control rod 54. The width of the block 53 is the same as the width of the long vertical groove 52 and the short vertical groove 57. The widths between the walls are consistent, and the card blocks 53 are respectively connected to the inner walls of the long vertical slot 52 and the short vertical slot 57. The difference lies in that the height of the control rod 54 can be controlled. The outer wall of the bottom end of the control rod 54 passes through and is slidably connected to the inner wall of the wind shield 2. The bottom end of the control rod 54 is rotatably connected with a baffle 55, and the outer wall of the baffle 55 is slidably connected to the inner wall of the wind shield 2. A cavity for accommodating the sliding of the baffle 55 is provided on the inner wall of the wind shield 2. A through slot 56 is provided on the baffle 55 and the inner wall of the wind shield 2. When the through slots 56 therebetween correspond to each other, the torque required by the motor 3 can be greatly reduced when closed. When the card block 53 is connected to the inner wall of the long vertical slot 52, the through slots 56 therebetween correspond to each other, and when the card block 53 is connected to the inner wall of the short vertical slot 57, the through slots 56 therebetween are staggered with each other, thereby achieving a closed and sealed effect.

[0032] Working principle: when the valve needs to be opened, the first bevel gear 41 is driven to rotate by the motor 3, and at the same time, the first bevel gear 41 drives the second bevel gear 42 to rotate, so that the second bevel gear 42 drives the rotating sleeve 51 to rotate, so that the rotating sleeve 51 drives the wind plate 2 at the bottom to rotate, thereby opening the exhaust channel. In this process, due to the provision of the through groove 56, the wind resistance of the wind plate 2 during rotation can be reduced, and then the block 53 is inserted into the inner wall of the short vertical groove 57, and when the wind plate 2 is reset, the torque required by the motor 3 can also be reduced, thereby increasing the service life of the motor 3. At the same time, when the wind plate 2 needs to be completely closed, the control rod 54 can be moved upward, so that the control rod 54 drives the block 53 to move upward and disengage from the long vertical groove 52, and the control rod 54 drives the baffle 55 to move upward, so that the baffle 55 and the through groove 56 on the wind plate 2 are staggered with each other, and at this time, the wind plate 2 can make the valve completely closed.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
