[0032] As a further implementation of the present application, the top end of the adjusting shell 31 is fixedly connected with a cover plate 32, the inner side of the cover plate 32 is provided with a circular hole 33, the extension rod 42 is installed on the inner side of the circular hole 33, and the extension rod 42 protrudes from the upper end of the cover plate 32. Through the above arrangement, a stable mounting position is provided for the extension rod 42, and the overall stability of the extension rod 42 during operation is ensured.

[0033] As a further implementation of the present scheme, the fixed bottom plate 36 is at the lower end of the U-shaped chute 34, the U-shaped chute 34 penetrates the upper end of the adjusting shell 31, and the outer side of the external block 45 is gap-fitted with the adjusting shell 31. Through the above arrangement, the gap-fitting relationship between the fixed bottom plate 36 and the U-shaped chute 34 and the gap-fitting between the external block 45 and the adjusting shell 31 ensure smooth sliding between the components, reduce friction, and ensure the flexibility of operation.

[0034] As a further implementation of the present scheme, the inside of the adjusting shell 31 is hollow, the inside of the fixed bottom plate 36 is a hollow structure, the fixed bottom plate 36 is located at the lower end of the bevel gear 23, and the bevel gear 23 is embedded and installed inside the adjusting shell 31. Through the above arrangement, the bevel gear 23 and the sleeve 43 can be flexibly rotated inside the adjusting shell 31, and the sleeve 43 drives the bevel gear 23 to rotate;

[0035] As a further implementation of the present scheme, a through hole is formed in the inner side of the combined discharge ball valve shell 1 close to the rotating roller 22, the rotating roller 22 is rotatably connected to the inner side of the through hole of the combined discharge ball valve shell 1, the upper end of the rotating roller 22 protrudes from the upper end of the fixed bottom plate 36, and the outer side of the rotating roller 22 is in close contact with the inner side of the sealing ring 35. Through the above arrangement, the rotating roller 22 can be flexibly rotated in the combined discharge ball valve shell 1, and is in close contact with the sealing ring 35, thereby sealing the fixed bottom plate 36 and the bevel gear 23;

[0036] As a further implementation of the present scheme, the upper end of the spring 46 is fixedly connected to the bottom end of the cover plate 32, the spring 46 is embedded and installed inside the adjusting shell 31, and the outer side of the sleeve 43 is in close contact with the inner side of the adjusting shell 31.

[0038] Working process: When opening and closing the ball valve body 21, press the handle body 41 downwards. The handle body 41 drives the extension rod 42, sleeve 43, and outer block 45 to move downwards. After the sleeve 43 moves downwards, the sleeve 43 drives the spring 46 to elastically extend. The outer block 45 slides on the inner side of the U-shaped groove 34. When the bottom end of the outer block 45 slides to the bottom end of the U-shaped groove 34, the bevel gear groove 44 meshes with the outer side of the bevel gear 23. When the handle body 41 is rotated... 1 drives the sleeve 43 to rotate, causing the sleeve 43 to rotate 90 degrees. The sleeve 43 drives the bevel gear 23, the rotating roller 22 and the ball valve body 21 to rotate through the bevel tooth groove 44. At this time, the ball valve body 21 rotates inside the combined unloading ball valve shell 1. The ball valve body 21 rotates 90 degrees. At the same time, the outer block 45 rotates from the right end to the rear end. The outer block 45 slides in the horizontal groove at the bottom of the U-shaped slide groove 34. At this time, the effect of controlling the opening and closing of the ball valve body 21 is achieved.

[0039] To prevent misoperation and monitor the rotation angle of the ball valve body 21 in real time, after the ball valve body 21 has been adjusted, the handle body 41 is released. Under the elastic pull of the spring 46, the sleeve 43, extension rod 42, and handle body 41 are pulled upward. At this time, the bevel gear groove 44 moves away from the bevel gear 23, and the outer block 45 slides inside the vertical groove of the U-shaped slide groove 34. Under the limiting action of the outer block 45 and the U-shaped slide groove 34, the handle body 41 cannot be turned, preventing accidental operation. When the outer block 45 moves to the bottom of the U-shaped slide groove 34, the sleeve 43 will mesh with the bevel gear 23. By monitoring the flow state of the ball valve body 21, the on / off state of the ball valve body 21 can be monitored in real time, thereby achieving precise control of the angle of the ball valve body 21. This avoids the problem of the handle mechanism and the ball valve thrust causing difficulty in determining the position, improves the accuracy and reliability of the ball valve operation, and reduces the safety risks caused by misoperation.

[0040] 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.
