Further alternatively, the feeding pipe 30 and at least two discharging pipes may be disposed on two opposite sides or the same side of the main flow pipe 20, or may be disposed on opposite vertical planes.

In use, slurry enters main flow pipe 20 from feed pipe 30 and is distributed to each of the tapping pipes 100 by main flow pipe 20. Slurry is output from each of the outlet pipes 100.

In the illustrated embodiment, each of the tapping pipes 100 described above is connected to the wall of the main flow pipe 20 by a connecting pipe fixing base 40. Further, in some embodiments of the present application, there is provided a tapping pipe 100 comprising: a first connection pipe 110, a second connection pipe 120, a restrictor 130, and a flow rate adjusting device 140; restrictor 130 has an internal passage 131; the inner passage 131 communicates with the first connection pipe 110 and the second connection pipe 120.

Further, the flow rate adjusting device 140 includes a connection portion 141 and a valve body portion 142.

Further, the connecting portion 141 is configured to drive the valve body portion 142 to move within the internal passage 131, and to block or communicate with the internal passage 131. Further optionally, referring to fig. 5, in some embodiments of the present application, the connecting portion 141 is configured to close or connect the internal passage 131 by rotationally driving the valve body portion 142 to move within the internal passage 131. Further alternatively, referring to fig. 6, in other embodiments of the present application, the connecting portion 141 is configured to close or communicate with the internal passage 131 by driving the valve body portion 142 to move in the internal passage 131.

Referring to fig. 4 and 3, in the illustrated embodiment, the internal passage 131 of the restrictor 130 is in the Y-direction. When connected, the inner passage 131 of the restrictor 130, the first connection pipe 110, and the second connection pipe 120 are all disposed in the Y direction so that the slurry is transported in the Y direction.

Further, in some embodiments, flow regulating device 140 is attached to the wall of restrictor 130 in a direction perpendicular to Y. In the embodiment shown in fig. 3, the flow regulating device 140 is arranged in the Z-direction.

For example, a direction that is not perpendicular and parallel to the Y direction. For example, a direction obliquely intersecting the Y direction.

Further, in some embodiments of the present disclosure, a mounting hole may be formed in a wall of the restrictor 130, and the flow regulator 140 may be mounted in the mounting hole. The connection portion 141 of the flow rate adjusting device 140 is inserted into the mounting hole, and has one end connected to the valve body portion 142 and the other end inserted into the mounting hole. The valve body 142 is disposed within the interior passageway 131 of the restrictor 130. The valve body 142 can be driven to move within the internal passage 131 by rotating the connecting portion 141.

Further, in some embodiments of the present application, the valve body 142 is spherical, and the valve body 142 is provided with a through hole 143; the valve body 142 can be moved to make the axis of the through hole 143 parallel or not parallel to the axis of the internal passage 131 by the driving of the connecting portion 141.

When the valve body 142 is driven by the connecting part 141 to move to make the axis of the through hole 143 parallel to the axis of the internal channel 131, the through hole 143 of the valve body 142 completely overlaps the internal channel 131, at this time, the internal channel 131 is communicated, the slurry is freely conveyed, and the flow rate is maximum; when the valve body 142 is driven by the connecting part 141 to move to a state that the axis of the through hole 143 is not parallel to and perpendicular to the axis of the internal channel 131, the through hole 143 of the valve body 142 is partially overlapped with the internal channel 131, and at this time, the internal channel 131 is communicated, the slurry is freely conveyed, and the flow rate is reduced; when the valve body 142 is moved by the connecting portion 141 so that the axis of the through hole 143 is perpendicular to the axis of the internal passage 131, the through hole 143 of the valve body 142 is displaced from the internal passage 131, and at this time, the internal passage 131 is blocked by the valve body 142, and the slurry cannot be transported. During the rotation of the connecting portion 141, the size of the overlapping portion of the through hole 143 of the valve body 142 and the internal passage 131 is adjusted, and in this process, the flow rate is adjusted.

Referring to fig. 5, in the illustrated embodiment, the spherical valve body 142 can rotate in the internal channel 131 by the connection part 141, and the axis of the through hole 143 is parallel or non-parallel to the axis of the internal channel 131 with the rotation of the valve body 142; when the axis of the through-hole 143 is parallel to the axis of the internal passage 131, the internal passage 131 is fully opened at this time; the slurry can flow in the inner passage 131. When the axis of the through-hole 143 is not parallel to but perpendicular to the axis of the internal passage 131, the slurry can flow in the internal passage 131 but at a flow rate smaller than a state where the axis of the through-hole 143 is parallel to the axis of the internal passage 131. When the axis of the through hole 143 is perpendicular to the axis of the internal passage 131, the valve body 142 blocks the internal passage 131, and slurry cannot flow in the internal passage 131. The adjustment of the size of the slurry flow is achieved in the process of making the axis of the through-hole 143 parallel, non-parallel and non-perpendicular to the axis of the internal passage 131.

Further, in some embodiments of the present application, the valve body 142 is not spherical in shape; the valve body portion 142 is able to move into abutment with the wall of the internal passage 131 or into clearance 144 with the wall of the internal passage 131, driven by the connection 141.

When the valve body 142 is moved to abut against the wall of the internal passage 131 by the driving of the connecting portion 141, the valve body 142 completely blocks the internal passage 131, the slurry cannot flow freely, and the valve body 142 closes the internal passage 131. When the valve body 142 moves to create a gap 144 with the wall of the internal passage 131 by the driving of the connecting portion 141, slurry can flow through the gap, and the valve body 142 opens the internal passage 131. The flow regulation is achieved during the rotation of the connection 141 to regulate the size of the gap 144 between the walls of the internal channel 131 of the valve body 142.

Further, in some embodiments of the present application, the valve body 142 is shaped as a cylinder; the connection portion 141 is connected to one end of a cylindrical valve body portion 142.

The gasket 150 mainly plays a role of buffering, abrasion caused by hard collision is avoided, and the sealing effect is improved; the gasket 150 is connected to the end of the valve body 142 away from the connecting portion 141 or is disposed on the wall surface of the internal passage 131, so that abrasion can be reduced, and sealing performance can be further improved.

For example, referring to fig. 6, in the illustrated embodiment, the gasket 150 is provided on the bottom surface of the valve body 142 having a rectangular parallelepiped shape, and when the connecting portion 141 rotates, the valve body 142 is driven to move up and down, so that the gasket 150 connected to the bottom surface of the valve body 142 abuts against the wall body of the internal passage 131. Due to the gasket 150, when the valve body 142 abuts against the wall of the inner passage 131, the sealing effect is improved, and a certain buffering effect is provided, so that the abrasion is reduced.
