It is connected to the upper edge of the upper cylinder 2 through several connecting plates 402; the outer cylinder 3 is arranged on the outer side of the lower part of the inner cylinder 4 and the upper edge is connected to the upper cylinder 2, and a plurality of intermediate partitions 6 are arranged on the upper edge of the outer cylinder 3. The outer cylinder 3 is connected to the inner cylinder 4 through the intermediate partitions 6, and the intermediate partitions 6 are located between the discharge port 401 and the discharge port 401; the slurry enters from the upper end of the feed cylinder 1, is discharged through the N discharge ports 401 of the inner cylinder 4, and then enters the next process through the discharge port 401 corresponding to the lower side of the discharge port 401.

[0024] like Figures 1 to 5 As shown, this embodiment provides a flow regulating valve suitable for use in a multi-channel slurry distributor in the prior art. Specifically, a flow regulating valve 8 is provided corresponding to each discharge port 401 on the inner cylinder 4, and each flow regulating valve 8 includes a horizontally arranged valve stem 801. A movable hole for the valve stem 801 to pass through is provided on the side wall of the upper cylinder 2. The valve stem 801 is inserted into the upper cylinder 2 along the movable hole. The valve stem 801 is connected to a valve plate 802 at one end located on the inner side of the upper cylinder 2, and is connected to an operating handle 804 at one end located on the outer side of the upper cylinder 2. When the operating handle 804 is rotated, the valve stem 801 moves horizontally, thereby driving the valve plate 802 to move horizontally, so that the discharge port 401 is in an open or closed state. The valve plate 802 is larger than the discharge port 401, and the valve plate 802 is an arc plate, and the arc is adapted to the inner cylinder 4. The valve stem 801 is arranged radially along the inner cylinder 4, and when the operating handle 804 is rotated, the valve stem 801 can move radially along the inner cylinder 4. In order to prevent the slurry from leaking out of the movable hole, a sealing ring 12 is provided inside the movable hole, and the valve stem 801 is connected to the upper cylinder 2 in a sliding and sealing manner through the sealing ring 12 .

[0025] like Figure 4 As shown, a fixing seat 7 is provided on the lower side of the valve stem 801 along the length of the valve stem 801, the fixing seat 7 is fixedly connected to the upper cylinder 2, a limiting ring 9 is provided on the fixing seat 7, the valve stem 801 passes through the limiting ring 9 and is limited by the limiting ring 9; the operating handle 804 is in a Z-shaped structure, including a first horizontal portion, a second horizontal portion and a vertical portion connecting the first horizontal portion and the second horizontal portion, a connecting rod 803 is hinged on the vertical portion, and the other end of the connecting rod 803 is hinged to the valve stem 801; a connecting ear 10 is also provided on the fixing seat 7, and the end of the first horizontal portion is hinged on the connecting ear 10; wherein, two connecting rods 803 are provided, which are respectively located on the left and right sides of the end of the valve stem 801 and the left and right sides of the vertical portion, and are hinged to the valve stem 801 and the vertical portion through a pin shaft.

Figure 5At this time, the first horizontal part rotates to the lower side, and the second horizontal part rotates to the upper side. The three nodes (the hinge point of the valve stem 801 and the connecting rod 803, the hinge point of the operating handle 804 and the connecting rod 803, and the hinge point of the operating handle 804 and the connecting ear 10) are located on the same straight line, and the position of the operating handle 804 is self-locking. At this time, the valve plate 802 cannot open autonomously, and this feeding path can be reliably cut off.

[0027] A dial 805 is also provided on one end of the fixed seat 7 located on the outer side of the upper cylinder 2. The dial 805 is a fan-shaped structure. A first limit hole 8041 is provided on the operating handle 804. A plurality of second limit holes 8051 are arranged at intervals on the dial 805 along the arc trajectory of the movement of the first limit hole 8041 when the operating handle 804 is rotated. After the operating handle 804 is rotated to adjust the material flow rate out of the discharge port 401 to an appropriate flow rate, a pin is used to penetrate the first limit hole 8041 and the corresponding second limit hole 8051 at this time, so as to fix the rotation angle of the operating handle 804, and then fix the position of the valve plate 802, so as to fix the gap between the discharge port 401 and the valve plate 802, thereby realizing the quantification of the size of the gap between the discharge port 401 and the valve plate 802.

[0028] Limiting nuts 11 are provided on both sides of the valve plate 802, and the limiting nuts 11 are threadedly connected to the valve stem 801; by adjusting the limiting nuts 11, the position of the valve plate 802 on the valve stem 801 can be adjusted, and then the operating handle 804 can be adjusted to rotate to the position as shown in FIG. Figure 5 After the valve plate 802 is in the position shown, it exerts a pressing force on the inner cylinder 4.

[0029] In order to further increase the wear resistance of the valve plate 802 and ensure the sealing performance at the discharge port 401 after the valve plate 802 is pressed tightly against the side wall of the inner cylinder 4, wear-resistant rubber is provided on the side of the valve plate 802 close to the discharge port 401.
