[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0032] The present invention relates to an L-type three-way ball valve, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes:

[0033] In this embodiment, a first valve body 3 is provided on the left side of the L-shaped three-way ball valve, and the first valve body 3 serves as the main body of this embodiment.

[0034] A second valve body 14 is provided on the right side of the L-type three-way ball valve. The second valve body 14 serves as the main body of this embodiment. Its structure is relatively simple, easy to manufacture and maintain, and reduces production and usage costs.

[0035] A ball 6 is installed on the valve body 3. The L-shaped three-way structure 17 is opened and closed by rotating the ball 6, so that the valve can realize the functions of fluid diversion, merging or flow direction switching.

[0036] A valve stem 7 is connected above the ball 6. The lower end of the valve stem 7 is connected to the ball 6, and the upper end is connected to the handle 10. The operator rotates the handle 10 to generate power, which is transmitted to the ball 6 through the valve stem 7, driving the ball 6 to rotate and opening or closing the L-shaped three-way structure 17.

[0037] A sealing structure 16 is provided on the outside of the valve stem 7. The sealing structure 16 can effectively reduce the friction of the valve stem 7 while ensuring good sealing performance.

[0038] An L-shaped three-way structure 17 is provided inside the valve body 3. The L-shaped three-way structure is opened and closed by rotating the handle 10 to drive the valve stem 7 and the ball 6 to rotate, so that the valve can realize the function of diverting, merging, or changing the flow direction of the fluid. When the handle 10 is in a certain position, the through hole 15 of the ball 6 is connected to two of the three channels of the first valve body 3 and the second valve body 14, realizing the directional flow of the fluid. When the handle 10 is rotated, the direction of the through hole 15 of the ball 6 changes, thereby switching the flow path of the fluid and realizing the function of diverting, merging, or changing the flow direction.

[0039] In this embodiment, an L-shaped three-way structure 17 is provided inside the valve body 3. The L-shaped three-way structure is opened and closed by rotating the handle 10 to drive the valve stem 7 and the ball 6 to rotate, enabling the valve to realize the functions of fluid diversion, merging, or flow direction switching. When the handle 10 is in a certain position, the through hole 15 of the ball 6 is connected to two of the three channels of the first valve body 3 and the second valve body 14, realizing the directional flow of fluid. When the handle 10 is rotated, the direction of the through hole 15 of the ball 6 changes, thereby switching the flow path of the fluid and realizing the functions of diversion, merging, or flow direction switching. This solves the problems in the prior art where traditional single-channel valves cannot meet the diverse needs under these complex working conditions, and it is difficult to realize the flexible switching of fluid diversion, merging, and flow direction. After long-term use, three-way valves are prone to leakage problems due to wear of the valve core and valve seat, which not only wastes resources but may also pollute the environment. There are also some technical problems where the adjustment accuracy of three-way valves is not high enough to meet the requirements of certain high-precision processes.

[0046] A packing gland 9 is installed above the packing 8; the packing gland 9 is fixedly connected to the second valve body 14. The packing gland 9 can apply stable pressure to the packing 8, so that the packing 8 can better fill the gap between the valve stem 7 and the second valve body 14, and enhance the sealing effect.

[0047] To achieve the above-mentioned technical effects, such as Figure 2 As shown, the first channel 11 and the second channel 12 are arranged in an L-shape to achieve the function of switching specific flow directions.

[0048] To achieve the above-mentioned technical effects, such as Figure 1 As shown, a through hole 15 is provided on the sphere 6. The through hole 15 is used for fluid flow. When the sphere rotates to different positions, the flow path of the fluid can also be changed.

[0049] To achieve the above-mentioned technical effects, such as Figure 1 and Figure 2 As shown, the first valve body 3 and the second valve body 14 are fixedly connected by a fully threaded stud 1 and a nut 2.

[0050] To achieve the above-mentioned technical effects, such as Figure 1 As shown, a gasket 4 is provided between the first valve body 3 and the second valve body 14. The gasket 4 serves to seal the space between the first valve body 3 and the second valve body 14, prevent media leakage, and ensure the safety and reliability of the system.

[0051] To achieve the above-mentioned technical effects, such as Figure 1 As shown, several sealing rings 5 ​​are provided between the first valve body 3, the second valve body 14 and the ball 6. The sealing rings 5 ​​can fill the tiny gaps between the ball 6 and the first valve body 3 and the second valve body 14 to prevent media leakage and maintain the sealing effect. The sealing rings 5 ​​can also reduce the friction between the ball 6 and the first valve body 3 and the second valve body 14, and extend the service life of the valve.

[0052] To achieve the above-mentioned technical effects, such as Figure 1 and Figure 2 As shown, a handle 10 is fixedly connected to the valve stem 7. The handle 10 is simple and intuitive to operate, and can quickly cut off or connect the fluid.

[0053] To achieve the above-mentioned technical effects, such as Figure 1 and Figure 2 As shown, the material of filler 8 is flexible graphite.

[0054] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
