[0021] The technical solution of the present invention will be clearly and completely described below through specific implementation methods.

[0022] The utility model is an L-type three-way ball valve structure, comprising a valve body 1, a valve core 3, a valve seat 5 and a fluid channel 10; the specific structure is as follows Figure 1 、 Figure 2 As shown, the valve body 1 is a sphere, and a valve cavity matching the valve core 3 is coaxially formed therein; the valve core 3 is coaxially installed in the valve cavity of the valve body 1, and an L-shaped channel 4 matching the interior of the fluid channel 10 is embedded thereon. Three valve seats 5 are sequentially spaced along the circumferential direction of the outer circumference of the valve body 1. Each valve seat 5 is arranged along the radial direction of the valve body 1 and is screwed and fixed to the corresponding position of the outer circumferential surface of the valve body 1 through the coaxially arranged fluid channel 10; two of the valve seats 5 are arranged in a colinear manner and are respectively arranged at 90 degrees to the third valve seat 5, and are respectively arranged in the same plane as the L-shaped channel 4; on each valve body 1, a connecting channel I 2 matching the fluid channel 10 is coaxially embedded and perpendicularly formed relative to each fluid channel 10, and on each valve seat 5, a connecting channel II 6 matching the fluid channel 10 is also coaxially embedded and perpendicularly formed, so that by rotating the valve core 3, any two fluid channels 10 can be connected or three fluid channels 10 can be cut off at the same time.

[0023] Among them, one end of the valve stem (not shown in the figure) is linked to the valve core 3 and is perpendicular to the plane where the three fluid channels 10 are located. The other end of the valve stem extends out of the valve body 1 in a radial vertical seal and is linked to the external driving mechanism, thereby driving the valve core 3 to rotate, thereby switching between connecting any two fluid channels 10 or disconnecting all three fluid channels 10 at the same time.

[0024] like Figure 1 、 Figure 2 As shown, the three fluid channels 10, the three valve seats 5 and the L-shaped channel 4 are all located on the same plane, and the axes of two of the fluid channels 10 are located on the same straight line, and the axis of the third fluid channel 10 is perpendicular to the axes of the other two fluid channels 10, thereby ensuring that the arc lengths between the third connecting channel Ⅰ2 and the other two connecting channels Ⅰ2 are equal.

[0025] like Figure 1 、 Figure 2 As shown, the two open ends of the L-shaped channel 4 and the internal shape of each fluid channel 10 are circular, and both ends of each connecting channel I2 and each connecting channel II6 are arc-shaped, and ensure that the two open ends of the L-shaped channel 4, each connecting channel I2, each connecting channel II6 and each fluid channel 10 are equal in diameter to each other; the diameters of the two open ends of the L-shaped channel 4 are not greater than one-eighth of the arc length of the circumference of the valve core 3, and ensure that each connecting channel I2 and each connecting channel II6 are coaxially arranged with the interior of the corresponding fluid channel 10.

The valve seat 5 is fixed by screwing the surface of the fluid channel 10 on the side of the valve body 1 with the corresponding connecting seat 8, and then the valve seat 5 is clamped and fixed, and it is ensured that each connecting channel I2 and connecting channel II6 are coaxially arranged with the interior of the corresponding fluid channel 10; at the large-diameter end of each valve seat 5 away from the surface of the valve body 1, springs 7 are evenly spaced and vertically provided along the circumferential direction thereof, and each spring 7 is spaced between the corresponding boss and the small-diameter end of the valve seat 5, and the end thereof away from the valve body 1 is in close contact with the corresponding surface of the corresponding fluid channel 10, thereby assisting the disassembly of the fluid channel 10 through the spring 7.

[0029] like Figure 1 、 Figure 2As shown, a valve seat sealing ring 9 is coaxially embedded between the connection between each valve seat 5 and the valve body 1, and each valve seat sealing ring 9 is spaced apart on the outside of the corresponding connecting channel I2, thereby ensuring the sealing between the valve body 1 and the corresponding valve seat 5; a second O-ring 12 is coaxially embedded between the outer circumferential surface of the small-diameter end of each valve seat 5 and the corresponding fluid channel 10, and the sealing between the valve seat 5 and the corresponding fluid channel 10 is ensured by the second O-ring 12; a first O-ring 11 is coaxially embedded between each connecting seat 8 and the corresponding boss, and each first O-ring 11 is coaxially spaced apart on the outside of the corresponding connecting channel II6, and the sealing between the fluid channel 10 and the corresponding connecting seat 8 is ensured by the first O-ring 11.

[0031] The working principle of this utility model:

[0032] Under the drive of the external driving mechanism, the valve stem drives the valve core 3 to rotate, so that any two fluid channels 10 are connected through the L-shaped channel 4 (such as Figure 1 As shown), or three fluid channels 10 are cut off simultaneously (as shown Figure 2 shown);

[0033] In some special places, when the fluid channel 10 is not stable enough to be fixed by screw connection alone, the clamping end of the mounting bracket can be coaxially sleeved into the clamping groove 13 of the corresponding fluid channel 10, thereby fixing and supporting the corresponding fluid channel 10 and ensuring its stability during use.

[0034] Beneficial effects of the utility model:

[0035] (1) When designing the position of the L-shaped channel 4, the utility model increases the coverage of the fan-shaped part of the valve core 3 on the inner side of the L-shaped channel 4, thereby realizing the function of simultaneously cutting off the three fluid channels 10, which can meet the needs of some special working occasions and has a wide range of applications;

[0036] (2) The utility model adopts an L-shaped channel 4 design, and its bending part adopts an arc transition, which is conducive to fluid buffering in the valve core 3 and avoids excessive impact force causing significant damage to the valve core 3;
