2. The flow control valve of claim 1, wherein: The regulating component (2) includes a spherical structure (21), the outlet is located at the bottom of the spherical structure (21), and the flow channel (22) is an involute flow channel (22) located on the side of the spherical structure (21), the flow area of ​​which gradually increases from one side of the spherical structure (21) to the other side.

3. The flow control valve of claim 2, wherein: The adjusting component (2) also includes a rotating shaft (23) and a limiting structure. One end of the rotating shaft (23) is connected to the ball structure (21), and the other end extends to the outside of the valve body (1) and is connected to a first rotating handle (24). The limiting structure is located between the rotating shaft (23) and the valve body (1) to limit the rotation direction of the ball structure (21).

4. The flow control valve of claim 3, wherein: The limiting structure includes a limiting block (20) on the rotating shaft (23) and a limiting groove (25) on the inner wall of the valve body (1). The limiting groove (25) is provided with a blocking part. The limiting block (20) is rotatably disposed in the limiting groove (25) and achieves rotational limiting by contacting and cooperating with the blocking part.

5. The flow control valve of claim 3, wherein: The first handle (24) is marked with a rotation direction.

6. The flow control valve of claim 2, wherein: The compensation component (3) includes a fixing plate (30) and a conical plug (37). The fixing plate (30) is located in the outlet. The fixing plate (30) is provided with a main flow channel (31) and a compensation channel (32). The conical plug (37) is movably inserted into the compensation channel (32) and can block the compensation channel (32).

7. The flow control valve of claim 6, wherein: The bottom of the conical plug (37) is provided with a limiting plate (35), which is movably disposed in the adjustment cavity (7) and can be sealed on the outer wall of the compensation groove (32).

8. The flow control valve of claim 7, wherein: The compensation component (3) also includes an adjusting rod (33), one end of which is threadedly connected to the conical plug (37) and the limiting disc (35), and the other end extends to the outside of the valve body (1) and is connected to a second rotating handle (34). By rotating the adjusting rod (33), the conical plug (37) and the limiting disc (35) can be driven to move axially.

9. The flow control valve according to claim 7, characterized in that: The adjustment cavity (7) is also provided with a limiting rod (36). One end of the limiting rod (36) is connected to the bottom of the fixing plate (30), and the other end is connected to the inner bottom wall of the adjustment cavity (7). The limiting plate (35) is slidably sleeved on the limiting rod (36).

10. The flow control valve of claim 1, wherein: The feed pipe (4) and the discharge pipe (5) are provided with a flange connection structure (6), and the flange connection structure (6) is provided with bolt holes.

11. A coating apparatus characterized by: A flow control valve comprising any of claims 1-10.
