Detailed Implementation

[0041] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0042] Example 1

[0043] Specific implementation examples Figures 1-3 As shown, the flow disturbance component used in this distributor is disposed between the liquid inlet 2 and the flow distribution section 3 of the distributor 1. The liquid inlet 2 and the flow distribution section 3 are connected. The flow disturbance component 4 includes a flow disturbance plate 5 adapted to the inner diameter of the liquid inlet 2. Several flow disturbance holes 6 are provided through the plate surface of the flow disturbance plate 5. The flow disturbance holes 6 are oblique holes, and their two ends are connected to the liquid inlet 2 and the flow distribution section 3 respectively.

[0044] Specifically, the turbulence component 4 is disposed in the distributor 1, located between the inlet hole 2 and the diversion section 3. It is used to turbulently transport the fluid input from the inlet hole 2 to the diversion section 3. The turbulence component 4 is in the form of a cylindrical turbulence plate 5. The turbulence plate 5 is provided with oblique turbulence holes 6. The turbulence holes 6 are opened between the two end faces of the turbulence plate 5 and extend in the direction between the axial and radial directions. When the fluid enters the turbulence holes 6, the flow direction is changed, thereby achieving the turbulence effect, which is beneficial to the mixing of the fluid and ensures uniform distribution in the diversion section 3.

[0045] like Figure 1 , 2 As shown in Figure 3, the liquid inlet 2 and the baffle 5 are mutually matched circles, and their axial directions are consistent. The baffle holes 6 are evenly distributed circumferentially on the baffle 5. The rotation angle and eccentricity of the baffle holes 6 are both greater than 0. The cross-section of the baffle holes 6 is circular and extends along a straight line.

[0046] Specifically, the inlet hole 2 and the spoiler 5 are circular, the spoiler 5 is equivalent to being radially blocked in the inlet hole 2, and the spoiler holes 6 are uniformly distributed. From the axial direction, the fluid flows through the spoiler holes 6 and is circumferentially rotated and offset, and is radially outwardly offset, which is conducive to uniform mixing, reduces flow rate and impact, and enhances the spoiler effect.

[0047] As shown in Figure 2 , an annular step 7 is arranged on the side wall of the inner end of the inlet hole 2, and the outer periphery of the spoiler 5 abuts against the annular step 7. An external thread (not specifically shown in the figure) is arranged on the outer side of the spoiler 5, and an internal thread (not specifically shown in the figure) is arranged in the inlet hole 2, and the external thread and the internal thread are engaged. The direction in which the external thread is screwed in is opposite to the direction of the rotational offset of the spoiler hole 6; the spoiler 5 is centrally provided with a rotational force applying part 10 on the end face away from the L-shaped notch 9, and the rotational force applying part 10 is annular.

[0048] Specifically, the annular step 7 is used to limit the installation position of the spoiler 5, so as to ensure that the spoiler 5 is stably arranged in the same direction in the inlet hole 2. The spoiler 5 and the inlet hole 2 are connected through threads, which reduces the possibility of disengagement. The extension direction of the spoiler hole 6 is rotated in the circumferential direction, and the fluid flows axially into the spoiler hole 6 and collides with the side wall of the spoiler hole 6 to change the flow direction. The collision here will exert a rotational force on the spoiler 5, and the direction of the force is opposite to the direction in which the external thread is screwed in, which can effectively prevent the spoiler 5 from rotating in the opposite direction and removing the anti-disengagement limit. The rotational force applying part 10 on the spoiler 5 is used for rotation, which facilitates the cooperation of the related anti-disengagement structure and facilitates the subsequent disassembly of the spoiler 5.

[0049] As shown in Figure 1 , 2 , 4, the distributor 1 comprises an inlet part 11 and a flow distribution part 3 which are integrally connected, the inlet part 11 is formed with an inlet hole 2, and the spoiler 5 is detachably arranged in the inlet hole 2.

[0050] Specifically, the liquid inlet part 11 of the distributor 1 is used to connect the corresponding pipeline to input the fluid, and the liquid distribution part 3 is used to distribute the fluid into multiple paths to achieve the distribution of the fluid. The spoiler 5 is arranged in the liquid inlet hole 2 to mix the input fluid to be distributed and reduce the flow rate to ensure uniform distribution of the fluid. The liquid outlet hole 12 extends between the large end and the small end. The large end has a larger outer diameter to provide space for arranging more liquid outlet holes 12. The liquid outlet hole 12 is arranged in the liquid outlet hole 12. The inner end of the liquid outlet hole 12 converges at the output end of the liquid inlet hole 2. The liquid outlet hole 12 extends outwardly from the convergence point to the large end. Each liquid outlet hole 12 forms a shape similar to a horn mouth. The liquid outlet hole 12 forms a flow cone 13 behind the convergence section to guide the fluid to each liquid outlet hole 12. The output end of the liquid outlet hole 12 is arranged on the conical surface 14 at the outer end of the large end. The conical surface 14 is perpendicular to the outer side wall of the liquid distribution part 3, so that the large end has a protruding shape in the middle, facilitating the connection of each liquid distribution pipe. The hollow area 15 in the middle of the conical surface 14 can realize the effects of light weight and low material cost without affecting the arrangement of the liquid outlet hole 12.

[0051] Specific working principle: The fluid is input from the liquid inlet hole 2. When the fluid passes through the spoiler 5, the fluid flows through each spoiler hole 6. The flow direction changes from axial to combined direction of circumferential rotation and radial outward expansion. Then the fluid with rotation flows into the distribution space between the liquid distribution part 3 and the spoiler 5, and then enters each liquid outlet hole 12 to output to the output end of the liquid distribution pipe.
