Preferably, the arch height B of the buffer arc tube wall 13 is 1/4 to 1/3 of the main tube diameter C. When the fluid is gathered into the diversion diverter from the first inlet 11, the buffer arc pipe wall 13 is utilized to rapidly expand and separate the fluid, so that the pressure of the fluid at the first inlet 11 is reduced, the fluid moves along the buffer arc pipe wall 13, the phenomenon of reverse interference is not easy to form between the fluid at the first inlet 11 and the fluid at the second inlet 21, and the fluid flows to the outlet 12 along the same path along the original direction side by side, so that the fluid resistance formed in the cavity is small; fluid entering from the first inlet 11 and the second inlet 21 is collected near point a of the outlet 12 and passes through the outlet 12, and the point a is near the center of the outlet 12, so that the collected fluid passes through the outlet 12 with low resistance.

The fluid entering through the second inlet 21 flows along the baffle 3 without creating turbulence inside the cavity of the draft tube 2.

Example 2

As shown in fig. 2 to 5, this embodiment adds a groove 14, a tension spring 15, and a turning block 16 on the basis of embodiment 1. The junction that the main flow pipe 1 is close to one side of first inlet 11 and drainage tube 2 is equipped with recess 14, and recess 14 sets up along the horizontal direction, and the left end of recess 14 is equipped with groove lateral wall 141, and the right-hand member of recess 14 is open structure, installs extension spring 15 and diversion piece 16 in the recess 14, and the left end of extension spring 15 is fixed in on groove lateral wall 141, and diversion piece 16 is connected to the right-hand member of extension spring 15, and diversion piece 16 can slide rightwards along recess 14, and the right-hand member of diversion piece 16 can stretch out recess 14. When part of the fluid entering from the first inlet 11 flows to the front end of the direction changing block 16, the flow direction is changed to the upper right under the flow guiding effect of the direction changing block 16, so that the flow resistance between the fluid and the fluid at the second inlet side below is reduced, and the convergence of the fluid at the two inlets to the center point of the outlet 12 is facilitated; meanwhile, part of the fluid entering from the first inlet 11 pushes the direction changing block 16 to one side of the outlet 12, so that the direction changing block 16 moves along the groove 14 under the thrust of the fluid, and the right end of the direction changing block 16 slightly stretches into the drainage tube 2, so that the fluid at the second inlet side at the point e is slightly pressed downwards, the flowing direction of the fluid at the point e is changed, and the collision of the fluid with the fluid at the first inlet side is avoided, so that the flowing resistance is increased. The tension spring 15 in the groove 14 can pull the turning block 16 back to one side of the first inlet 11, thereby resetting it.

As shown in fig. 5, the front and rear side walls of the groove 14 are respectively provided with a horizontal limiting groove 142, the front and rear sides of the turning block 16 are respectively provided with limiting blocks 165 matched with the limiting grooves 142, and the limiting blocks 165 are inserted into the limiting grooves 142. The limiting block 165 and the limiting groove 142 can ensure that the direction changing block 16 always moves along the horizontal direction in the groove 14, so that the right end of the direction changing block 16 is prevented from being separated from the groove 14 by the upward impact force of the second inlet side fluid, and the working stability of the direction changing block 16 is improved.

As shown in fig. 5, a bowl-shaped direction-changing main body 164 is arranged on the upper side of the direction-changing block 16, the direction-changing main body 164 is closely contacted with the pipe wall of the main flow pipe 1, and a plurality of branches are prevented from being formed by leakage of fluid between the direction-changing block 16 and the pipe wall of the main flow pipe, so that the direction-changing effect of the fluid is ensured; the top of the direction changing body 164 includes an arc-shaped direction changing surface 161 and a horizontal guide surface 162 connected to each other, and the arc-shaped direction changing surface 161 is located on a side close to the tension spring 15. The curved redirecting surface 161 may direct fluid from the first inlet side to the upper right.

As shown in fig. 4, a side guide surface 163 inclined to the left is provided on the side of the direction changing block 16 away from the tension spring 15, and the upper and lower ends of the side guide surface 163 are respectively connected with the horizontal guide surface 162 and the bottom surface of the direction changing block 16. The lateral flow guide surface 163 may guide the fluid of the second inlet side toward the outlet side.

As shown in fig. 4, the length of the turning block 16 is smaller than the length of the groove 14. In the initial state, the right end of the turning block is retracted in the groove 14 under the tension of the tension spring 15.

when the fluid is converged, after the fluid enters from the first inlet and the second inlet respectively, part of the fluid at the first inlet side moves forward along the wall of the buffer arc-shaped pipe, and part of the fluid moves forward along the direction changing block; and when the pressure of the two streams of fluid is converged at the point a, an interference phenomenon is not formed, and the two streams of fluid side by side flow along the same path along the original direction to the outlet, so that the flow resistance is small.

When the fluid is split, the fluid can be immediately split into two flows after entering the cavity from the outlet, one of the two flows runs along the fixed direction of the guide plate towards the second inlet, and the other one runs towards the first inlet directly. If the diameters of the first inlet and the second inlet are different, the fluid entering the main flow pipe and the drainage pipe can be automatically split at the point a according to the pipe diameters.
