[0002] In the technical field of conical valve equipment, the transmission mechanism as one of the core components of the conical valve, its design and structure directly affect the performance, installation convenience and space adaptability of the conical valve. The traditional conical valve transmission mechanism usually adopts a fixed shaft type design, such as Figure 4 , that is, two fixed shaft transmission rods are connected through a reversing gear box, and these transmission rods are further connected with a gate sleeve opening adjusting gear box, and the gate sleeve opening adjusting gear box is responsible for driving the gate sleeve assembly to realize the opening and closing of the valve. However, this design has significant limitations, especially in the face of limited installation space environment.

[0003] Specifically, the two transmission rods of the traditional conical valve transmission mechanism cannot flexibly adjust the distance between the reversing gear box and the gate sleeve opening adjusting gear box due to its fixed shaft characteristics. This design feature may not be a problem in space abundant occasions, but in many industrial applications, compact pipeline systems or space limited installation environment, it has become a key factor restricting the application of conical valves. The fixed transmission rod distance requires the installation area to provide enough space to accommodate the entire transmission mechanism, which not only increases the installation difficulty, but also may not be implemented due to insufficient space, thereby limiting the wide application range of the conical valve.

[0004] In addition, the traditional transmission mechanism design often occupies a large area, which is not conducive to efficient layout and optimal configuration in limited space, especially in the field with strict requirements on space utilization. Therefore, how to reduce the occupied space while maintaining the good performance of the conical valve and improve the installation flexibility has become a technical problem to be solved.

[0005] In summary, the existing conical valve transmission mechanism has the problem of insufficient space adaptability, especially the volume problem when installed in limited space, which seriously restricts the promotion and application of the conical valve. In view of this, the utility model aims to provide an improved conical valve transmission mechanism. UTILITY MODEL CONTENTS

It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0021] Please refer to Figures 1 to 3The application discloses a transmission mechanism for a conical valve, which comprises a driving unit 1 serving as a power source of the whole transmission mechanism, wherein the driving unit provides necessary rotating power; a power shaft of the driving unit extends into a reversing gear box 2, thereby realizing direct power transmission, reducing energy loss in the power transmission process, improving transmission efficiency, and reducing space occupation. A driving reversing bevel gear 3 is arranged on the power shaft in the reversing gear box, two sides of the driving reversing bevel gear are respectively meshed with driven reversing bevel gears 4, the driven reversing bevel gears are all arranged on a rotating shaft 5, power is branched and transmitted through meshing of the bevel gears, and stability and reliability of transmission are ensured. The rotating shaft is connected with an input shaft of a gate sleeve opening degree adjusting gear box through an adjustable power transmission assembly 6, and is used for adjusting a distance between the reversing gear box and the gate sleeve opening degree adjusting gear box. Flexible adjustment of the distance and angle between the reversing gear box and the gate sleeve opening degree adjusting gear box is realized, so that the transmission mechanism can adapt to different installation environments and space limitations, and adaptability and flexibility of the transmission mechanism are improved. Meanwhile, the adjustable power transmission assembly can reduce transmission errors caused by installation errors or deformation, shorten a valve body flange seat in actual production and processing, and make the driving unit and the valve body as close as possible, so that transmission precision and stability are improved.

[0022] The adjustable power transmission assembly 6 comprises a first flange coupling 6-1 connected with the rotating shaft 5, a first cross shaft universal joint 6-2 connected with the first flange coupling, a transition adjustment driving rod 6-3 connected with the first cross shaft universal joint, a second cross shaft universal joint 6-4 connected with the transition adjustment driving rod, a second flange coupling 6-5 connected with the second cross shaft universal joint, and an input shaft 7-1 of a gate sleeve opening degree adjusting gear box 7 connected with the second flange coupling.

[0023] The adjustable power transmission assembly 6 realizes flexibility and adjustability of power transmission in the transmission mechanism, and significantly improves adaptability of the conical valve transmission mechanism under different installation environments and space conditions. Specifically, the assembly ensures stable transmission of power from the reversing gear box to subsequent components through the close connection of the first flange coupling 6-1 and the rotating shaft 5. Then, the first cross shaft universal joint 6-2 provides the possibility of first direction adjustment for the transmission path, so that the power can be smoothly diverted and transmitted to the transition adjustment driving rod 6-3.

[0024] The transition adjustment driving rod 6-3, as a key adjustment element in the assembly, not only undertakes the task of power transmission, but also realizes flexible adjustment of transmission distance and angle through the telescopic and rotatable characteristics. This design enables the transmission mechanism to be accurately adjusted and optimized according to space limitations and installation requirements in actual application scenarios, thereby maximizing space saving and improving installation efficiency.

[0025] Further, the cooperation of the second cross shaft universal joint 6-4 and the second flange coupling 6-5 again provides the power transmission path with the ability of direction adjustment, and finally stably transmits the power to the input shaft 7-1 of the brake sleeve opening adjusting gear box 7. Through the adjustment of the two cross shaft universal joints, the entire power transmission assembly realizes the all-around adjustment of the transmission distance, angle and transmission path, greatly enhancing the flexibility and adaptability of the transmission mechanism.

[0026] In summary, the adjustable power transmission assembly 6 solves the installation problem of the traditional transmission mechanism in the space-limited environment with its unique adjustable design, and provides more extensive and flexible possibilities for the application of the conical valve transmission mechanism.

[0027] Further preferably, the first flange coupling is connected to the rotating shaft through a spline or a key; and the second flange coupling is connected to the input shaft of the brake sleeve opening adjusting gear box through a spline or a key. This significantly optimizes the assembly process and power transmission performance. In assembly, this standardized connection method simplifies the installation steps, improves the assembly efficiency and accuracy, ensures the stable combination between the transmission components, and is convenient for later maintenance and replacement. In power transmission, the efficient meshing of the spline and the key ensures the smooth and continuous transmission of the power, reduces the energy loss and transmission error. Especially, the multi-tooth design of the spline automatically centers and uniformly distributes the load, further improving the stability and reliability of the transmission. In addition to the above-mentioned spline and key connection method, a fastening screw perpendicular to the axial direction can also be used to connect the first flange coupling and the rotating shaft, and the second flange coupling and the input shaft.
