Description

Technical Field

[0001] This utility model relates to the field of electric tilting valve technology, specifically a novel electric tilting valve. Background Technology

[0002] An electric tilting valve is a valve that achieves tilting action through electric control, primarily used for on / off control of low-pressure pipeline media. It is driven by an electric actuator, rotating a valve disc or butterfly plate to open and close. Electric tilting valves have a simple structure, are flexible in operation, and are suitable for various industrial applications.

[0003] Existing electric tilt valve technology has the following problems: existing electric tilt valves mostly use multi-blade independent adjustment, which is prone to asynchrony, and maintenance requires complete disassembly, which is time-consuming and labor-intensive. Therefore, a new type of electric tilt valve is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a novel electric tilting valve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel electric tilting valve, comprising a support tube,

[0006] Both ends of the support tube are fixedly connected to annular connecting plates. Several mounting holes are opened in the middle of the annular connecting plates. Both ends of the support tube are provided with annular limiting grooves. An annular rubber ring is fixedly connected to the middle of the inner wall of the annular limiting groove.

[0007] Furthermore, a support plate is welded to the left side of the support tube, and a servo motor is fixedly connected to the top of the support plate.

[0008] Furthermore, the output end of the servo motor is fixedly connected to a rotating shaft, which passes through the support tube.

[0009] Furthermore, the inner wall of the support tube is provided with an upper louver, a middle louver, and a lower louver arranged sequentially from top to bottom, and an arc-shaped limiting groove is provided at the front end of each of the upper louver, middle louver, and lower louver.

[0010] Furthermore, both ends of the arc-shaped limiting groove are threaded with rivet screws, and one end of the rivet screw is threadedly connected to the rotating shaft.

[0011] Furthermore, one end of the rivet screw is threadedly connected to a rotating rod, which passes through the support tube.

[0012] Furthermore, a collar is provided on the outer side of the rotating rod on the left side of the support tube, and one end of the collar is welded to the support tube.

[0013] Furthermore, each of the rotating rods on the right side of the support tube is fixedly connected to a connecting rod, and each of the connecting rods is fixedly connected to a fixed shaft on both the left and right sides, with a connecting rod rotatably connected to the middle of the fixed shaft.

[0014] Furthermore, a support frame is welded to the lower right end of the support tube, and a mounting plate is welded to one end of the support frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By incorporating annular rubber rings and limiting grooves, with rubber rings embedded in the annular limiting grooves at both ends of the support pipe, a double seal is formed through compression, solving the leakage problem caused by vibration or deformation in traditional valve bodies. The annular connecting plate and mounting holes support quick flange installation, ensuring uniform stress on the sealing surface and avoiding localized stress concentration caused by traditional bolted connections. Furthermore, the servo motor and rotating shaft allow for precise adjustment of the louver opening angle (±0.5° accuracy), achieving linear regulation of flow or pressure. Traditional valves, relying on manual or pneumatic control, suffer from low precision and slow response. The connecting rod and connecting arm further enhance this effect. The transmission system composed of rods ensures synchronous operation of the upper, middle, and lower louvers, avoiding turbulence or wear caused by asynchronous operation of multiple blades in traditional valves. By setting up support plates and support pipes, which are welded together, the motor load capacity is enhanced. The support frame and mounting plate provide a stable base, making it more resistant to vibration and impact than traditional split valve bodies. By setting up an annular rubber ring, made of fluororubber or EPDM, it is resistant to high temperature and media corrosion, and its service life is 2-3 times longer than that of traditional rubber gaskets. By setting up louvers and press-fit screws, the louvers are connected to the rotating shaft through press-fit screws. Loosening the screws allows for quick replacement or adjustment of the blade angle, whereas traditional valves require disassembly of the entire valve body. Attached Figure Description

[0025] Please see Figure 1-3This utility model provides a novel electric tilting valve technical solution: A novel electric tilting valve includes a support pipe 1, with annular connecting plates 2 fixedly connected to both ends of the support pipe 1. By setting the annular connecting plates 2 and mounting holes 3, the mounting holes 3 on the annular connecting plates 2 support quick flange installation, ensuring uniform stress on the sealing surface and avoiding localized stress concentration caused by traditional bolt direct connection. Several mounting holes 3 are opened in the middle of the annular connecting plates 2. Annular limiting grooves 4 are opened at both ends of the support pipe 1. Annular rubber rings 5 ​​are set in the limiting grooves, and the rubber rings are embedded in the annular limiting grooves 4 at both ends of the support pipe 1. Through compression, a double seal is formed, solving the leakage problem caused by vibration or deformation of the traditional valve body. Annular rubber rings 5 ​​are fixedly connected to the inner wall of the annular limiting grooves 4. The rubber ring 5, made of fluororubber or EPDM, is resistant to high temperature and media corrosion, and its lifespan is 2-3 times longer than that of traditional rubber gaskets. A support plate 6 is welded to the left side of the support tube 1. By setting the support plate 6 and the support tube 1 and welding the support plate 6 to the support tube 1, the load capacity of the motor is enhanced. The support frame 20 and the mounting plate provide a stable base, which is more resistant to vibration and impact than traditional split valve bodies. A servo motor 7 is fixedly connected to the top of the support plate 6. By setting the servo motor 7 and the rotating shaft 8, the rotation angle of the rotating shaft 8 can be controlled by the servo motor 7, and the opening and closing degree of the louver can be precisely adjusted (±0.5° accuracy) to achieve linear regulation of flow or pressure. Traditional valves rely on manual or pneumatic control, which has low accuracy and slow response. The output end of the servo motor 7 is fixedly connected to the rotating shaft 8.

[0026] A rotating shaft 8 passes through a support tube 1. The inner wall of the support tube 1 has an upper louver 9, a middle louver 10, and a lower louver 11 arranged sequentially from top to bottom. Each of the upper louver 9, middle louver 10, and lower louver 11 has an arc-shaped limiting groove 12 at its front end. By using louvers and rivet screws 13, the louvers are connected to the rotating shaft 8. Loosening the screws allows for quick replacement or adjustment of the blade angle. Traditional valves require disassembling the entire valve body. Both ends of the arc-shaped limiting groove 12 are threaded with rivet screws 13. One end of the rivet screw 13 is threaded to the rotating shaft 8, and the other end is threaded to a rotating rod 19, which passes through the support tube 1. A collar 14 is provided on the outer side of the rotating rod 19 on the left side of the support pipe 1. One end of the collar 14 is welded to the support pipe 1. The rotating rod 19 on the right side of the support pipe 1 is fixedly connected to a connecting rod 16. By setting the connecting rod 16 and the connecting rod 18, the transmission system composed of the connecting rod 16 and the connecting rod 18 ensures that the upper louver 9, the middle louver 10, and the lower louver 11 move synchronously, avoiding turbulence or wear caused by the asynchronous movement of multiple blades in traditional valves. The left and right sides of the outer side of the connecting rod 16 are fixedly connected to a fixed shaft 17. The middle of the fixed shaft 17 is rotatably connected to the connecting rod 18. A support frame 20 is welded to the lower right end of the support pipe 1. A mounting plate is welded to one end of the support frame 20.

[0027] In use, when the servo motor 7 is started, the rotating shaft 8 drives the upper louver 9, middle louver 10, and lower louver 11 to rotate synchronously around the shaft. The angle of the louvers is adjusted and locked by the arc-shaped limiting groove 12. The parallel four-bar linkage, consisting of the connecting rod 16, the fixed shaft 17, and the connecting rod 18, further ensures the uniformity of the opening and closing angles of each louver. When the louvers are closed, the annular rubber ring 5 is pressed against the external connecting parts to achieve a seal; when open, the medium passes through the gaps between the louvers. Through the precise control of the servo motor 7, the tilt angle of the louvers can be adjusted to achieve linear control of flow rate or pressure.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
