The utility model discloses a three-way ball valve with controllable flow rate, including a rotating disk 1, a control disk 2, a connecting rod 3, a water inlet 4, a first water outlet 5, a second water outlet 7 and a ball valve body 8. A push handle 101 is fixed on the right side of the rotating disk 1, the lower side of the rotating disk 1 is the control disk 2, the lower side of the control disk 2 is connected to the connecting rod 3, the connecting rod 3 is connected to the upper side of the ball valve body 8, the left side of the ball valve body 8 is connected to the water inlet 4 through the water inlet pipe 401, the right side of the ball valve body 8 is connected to the first water outlet 5 through the first water outlet pipe 501, the front side of the ball valve body 8 is connected to the second water outlet 7, and the middle of the water inlet pipe 401 has two sections, and the middle of the two sections is connected by a filtering device 6. There are protrusions 202 on the front, back, left and right of the control disk 2, and there are spring blocks 201 on the side of the control disk 2 and below the protrusions 202. There are scale lines 203 of different angles in the blank space of the control disk 2. Both the protrusions 202 and the spring blocks 201 can position the push handle 101 to ensure that the water flow rate reaches the maximum when the inner ball 9 is in the L or T shape or circle closed state. The scale lines 203 can accurately control the rotation angle of the rotating disk 1, so as to achieve the purpose of controlling the flow rate. The interior of the connecting rod 3 is connected to the inner ball 9, the left side of the inner ball 9 is the water inlet port 10, the right side of the inner ball 9 is the first water outlet port 11, and the front of the inner ball 9 is the second water outlet port 12. The radius of the water inlet port 10, the first water outlet port 11, and the second water outlet port 12 is half the radius of the inner ball 9. The water inlet 10 is matched with the water inlet pipe 401, the first water outlet pipe 501 is matched with the first water outlet 11, the second water outlet pipe is matched with the second water outlet 12, and the water inlet 10, the first water outlet 11 and the second water outlet 12 are consistent in size, structure and height.

[0027] Specific implementation principle: When the utility model is used, the three-way ball valve is assembled on the pipeline, and water passes through the water inlet 4 and reaches the filter device 6. The impurities visible to the naked eye in the flowing water are initially filtered through the annular filter 604 inside the filter device 6. After the fine sediment is filtered twice through the activated carbon bamboo charcoal filter ring 605, it passes through the water inlet pipe 401 and the water inlet port 10 to reach the inner ball 9, passes through the first water outlet pipe 501 and the second water outlet pipe, and flows out from the first water outlet 5 and the second water outlet 7. When the flow rate needs to be controlled, the push handle 101 can be pulled clockwise, and the scale line 203 on the control disk 2 is displayed according to the rotation angle of the control rotating disk 1 on the control disk 2. When the angle is 45 degrees, the flow rate is small. When the angle is equal to 90 degrees, the T-type three-way becomes an L-type two-way, and the first water outlet 5 is intercepted. The protrusion 202 will be released from the push handle 101, and the bullet 201 will be retracted and popped out of the square, indicating that the flow rate is the maximum at this time.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
