Since the inner diameter of the second flow path 1b gradually decreases in the direction away from the first flow path 1a, when the air flow flows through the second flow path 1b in the first flow path 1a, the air flow moves from the end with the larger inner diameter of the second flow path 1b to the end with the smaller inner diameter, the speed increases, the pressure decreases, a pressure difference band is formed, and the air flow can be better pushed to move towards the inside of the second flow path 1 b; moreover, the inner diameter of the second flow passage 1b gradually decreases in a direction away from the first flow passage 1a, so that the second flow passage 1b can be designed to interface with branch pipes of different inner diameters.
It should be understood that the flow-guiding tee joint can be a tee joint, and also can be a four-way joint, a five-way joint and the like.
It should be understood that the first flow channel 1a may be cylindrical, prismatic, etc.; the shape of the second flow channel 1b may be conical, truncated cone, pyramid, etc.; the taper of the inner wall of the second flow path 1b may be set as required.
In one embodiment, both sides of the second flow channel 1b are symmetrical along the axis of the second flow channel 1 b.
Through the arrangement, the symmetrically designed second flow channel 1b enables air flow to be more balanced, and vortex and turbulence are reduced, so that the flow guiding efficiency and stability of the second flow channel 1b are improved; because the symmetrically designed air flow is more stable, the noise generated when the air flow flows through the second flow passage 1b is also lower; the symmetrical second flow channel 1b can reduce vibration, thereby improving the service life and reliability of the second flow channel 1 b; the design of the symmetrical second flow channels 1b makes installation and maintenance more convenient, since they can be installed in any direction without taking into account directionality.
It should be understood that the cross-sectional shape of the first flow channel 1a may be circular, rectangular, elliptical, etc.
In one of these embodiments, the taper of the inner wall of the second flow channel 1b is less than or equal to 45 °.
The smaller the taper of the second flow channel 1b is, the smaller the resistance of the air flow is when the air flow passes through the air pipe, and the taper of the second flow channel 1b is designed to be smaller than or equal to 45 degrees, so that the resistance of the second flow channel 1b can be effectively reduced, and the flow guiding efficiency of the second flow channel 1b is improved; the smaller the taper of the second flow passage 1b, the less noise the air flow generates when passing through the second flow passage 1b, and therefore, designing the taper of the second flow passage 1b to be 45 ° or less can effectively reduce the noise of the air flow passing through the second flow passage 1 b.
As shown in fig. 1, in one embodiment, the tee body 1 includes a first communication pipe 11 and a second communication pipe 12, the first communication pipe 11 is formed with a first flow channel 1a, the second communication pipe 12 is connected to the first communication pipe 11, the first communication pipe 11 and the second communication pipe 12 are disposed to intersect, and the second communication pipe 12 is formed with a second flow channel 1b.
The three-way body 1 is formed by combining the first communication pipe 11 and the second communication pipe 12, and the first flow passage 1a and the second flow passage 1b are formed by combining the first communication pipe 11 and the second communication pipe 12 which are arranged in a crossing manner.
It should be understood that the first communication pipe 11 and the second communication pipe 12 may be integrally formed, or the first communication pipe 11 and the second communication pipe 12 may be formed by separately processing and then connecting the separately processed first communication pipe and the second communication pipe 12.
It should be understood that the first communication pipe 11 may be a through body and the second communication pipe 12 may be a tapered through head, but the names and structures of the first communication pipe 11 and the second communication pipe 12 are not limited to the above-mentioned through body and tapered through head.
As shown in fig. 1, 2, 3, 4, 6 and 7, in one embodiment, the second communication pipe 12 gradually decreases in outer diameter in a direction away from the first communication pipe 11.
With the above arrangement, the shape of the peripheral wall of the second communication pipe 12 is defined so that the second communication pipe 12 can be connected to branch pipes of different inner diameters.

It should be understood that the materials of the first communication pipe 11 and the second communication pipe 12 may be PVC (polyvinyl chloride), PU (polyurethane), etc.
As shown in fig. 1, 2, 6 and 7, in one embodiment, the flow guiding tee further includes at least one flow guiding portion 2, the flow guiding portion 2 is disposed in the first flow channel 1a, and the flow guiding portion 2 is disposed at an angle with respect to an extending direction of the first flow channel 1 a.
By providing the flow guide portion 2, when the air flow passes through the flow guide portion 2, the air flow can be guided from the first flow passage 1a into the second flow passage 1b under the guidance of the flow guide portion 2, and the flow rate of the fluid entering the second flow passage 1b can be increased.
As shown in fig. 1 and 2, in one embodiment, the cross section of the flow guiding portion 2 along the extending direction of the first flow passage 1a is arc-shaped.
When the fluid passes through the arc-shaped flow guide part 2, the fluid contacts with the arc surface of the flow guide part 2, the fluid is guided to enter the second flow channel 1b under the guidance of the arc surface, and the resistance is relatively small when the arc surface guides the fluid, so that the interference of the flow guide part 2 to the fluid is reduced.
It should be understood that the cross section of the flow guiding portion 2 along the extending direction of the first flow channel 1a may be circular arc-shaped, crescent-shaped.
In one embodiment, the connection point between the first communication pipe 11 and the second communication pipe 12 is in circular arc transition, and the chord length of the cross section of the flow guiding portion 2 along the extending direction of the first flow passage 1a is equal to the chord length of the cross section of the circular arc transition surface 1 d.
Through the arc transition of the first communicating pipe 11 and the second communicating pipe 12, the occurrence of sharp corners can be reduced, and the sharp corners are prevented from interfering the flowing of circulation; by making the cross-sectional chord length of the flow guiding portion 2 equal to the cross-sectional chord length of the circular arc transition surface 1d between the first communication pipe 11 and the second communication pipe 12, the flow direction of the fluid flowing through the circular arc transition surface 1d in the first flow passage 1a is the same as the flow direction of the fluid flowing through the flow guiding portion 2, so that the fluid is more uniformly distributed on the pipe cross section.
It should be understood that the arc transition surface 1d between the first communication pipe 11 and the second communication pipe 12 may exist between the first communication pipe 11 and the second communication pipe 12 in a real manner or may be a virtual surface.
As shown in fig. 1, 2, 6 and 7, in one embodiment, the number of the flow guiding parts 2 is plural, the plurality of flow guiding parts 2 are concentrically and alternately arranged, and the chord lengths of the plurality of flow guiding parts 2 are equal.
By arranging the plurality of diversion parts 2, the plurality of diversion parts 2 can play a role in diversion, and the fluid is converted into a plurality of strands of smaller fluid, so that the fluid is more uniformly distributed on the section of the pipeline, and because the plurality of diversion parts 2 are concentrically and at intervals, the plurality of diversion parts 2 enable the guided fluid to regularly flow into the second flow channel 1b when the fluid is guided, and the irregular motion product fluid damping of the fluid in the first flow channel 1a and the second flow channel 1b is reduced; the equal-chord-length flow guide part 2 has a simple structure and is convenient to manufacture and maintain.
It should be appreciated that while increasing the number of flow directors 2 may increase the uniform distribution of the fluid, it may also result in an increase in pressure loss. Therefore, these two factors need to be weighed during the design process to achieve optimal fluid distribution and minimal pressure loss, and in one embodiment, the number of flow directors 2 is less than or equal to four.
In one embodiment, the flow guiding portion 2 has flexibility, and the cross section of the flow guiding portion 2 is in a strip shape, and the plurality of flow guiding portions 2 are distributed at intervals along a direction away from the air inlet end of the first flow channel 1 a.
Through the arrangement, when the fluid in the first flow channel 1a flows through the flow guiding part 2, the flow guiding part 2 can be forced to have the circular arc-shaped cross section along the axial direction of the first flow channel 1a under the forcing of the pressure of the fluid, so that the flow guiding part 2 with the strip-shaped cross section can still have the circular arc-shaped flow guiding function when not being pressed; moreover, compared with the guide part 2 with the circular arc-shaped cross section, the guide part 2 with the bar-shaped cross section is simpler to manufacture and lower in cost; in order to achieve equal chord lengths of the compressed air flow guiding portions 2, in this embodiment, when the air flow guiding portions 2 are bent to form the air flow guiding portions 2 with coaxial and equal chord lengths, the diameters of the air flow guiding portions 2 with circular arc-shaped cross sections are different along the direction away from the center of the circle, and the required arc lengths of the air flow guiding portions 2 are different, so that the chord lengths of the air flow guiding portions 2 with circular arc-shaped cross sections formed after the compressed deformation are equal along the direction away from the air inlet end of the first flow channel 1 a.
It should be understood that the material of the flow guiding portion 2 may be PVC (polyvinyl chloride), PU (polyurethane), rubber, latex, silica gel, etc.
As shown in fig. 1, in one embodiment, the axis of the first flow channel 1a intersects with the axis of the second flow channel 1b, and divides the first flow channel 1a into four regions, of which the region near the air intake side of the first flow channel 1a and the region near the second flow channel 1b is the installation region 1c, and the flow guiding portion 2 is installed in the installation region 1c.
By the above limitation, the diversion part 2 can be installed only in a limited area, the diversion effect of the diversion part 2 in the installation area 1c is good, the damping to the fluid is small, and the diversion part 2 is installed outside the installation area 1c, and the damping to the fluid of the diversion part 2 is increased more obviously than the diversion effect.
It should be understood that the axis of the first flow channel 1a and the axis of the second flow channel 1b may be perpendicular to each other, distributed at an acute angle, distributed at an obtuse angle, etc.
In one embodiment, both ends of the flow guiding portion 2 in the longitudinal direction are respectively connected to the inner walls of the mounting region 1c, and the flow guiding portion 2 is arranged in a direction perpendicular to a plane formed by the axis of the first flow passage 1a and the axis of the second flow passage 1 b.
Through the above definition, the connection mode of the flow guiding part 2 and the first communication pipe 11 is limited, and in addition, the two ends of the flow guiding part 2 are respectively connected with the inner wall of the first communication pipe 11, so that the middle part with relatively large air pressure in the first communication pipe 11 can drive the middle part of the flow guiding part 2 to deform, the section deformation of the flow guiding part 2 is arc-shaped, and the section deformation degree of the flow guiding part 2 gradually decreases along the direction close to the inner wall of the first communication pipe 11, and the air pressure gradually decreases along the direction close to the inner wall of the first communication pipe 11 in the first communication pipe 11, so that the flow guiding amount of the flow guiding part 2 decreases along the direction close to the inner wall of the first communication pipe 11.
As shown in fig. 1 and 2, in one embodiment, the installation area 1c has a virtual surface 1e tangential to both the axis of the first flow channel 1a and the axis of the second flow channel 1b, the arc transition surface 1d between the first communicating pipe 11 and the second communicating pipe 12 is a virtual surface, the arc transition surface 1d is concentric with the virtual surface 1e, the included angles of the two are 90 °, the connection line between the end of the arc transition surface 1d and the center of the circle is perpendicular to the axis of the first flow channel 1a, and the cross-sectional chord length of the flow guiding portion 2 along the extending direction of the first flow channel 1a is equal to the cross-sectional chord length of the arc transition surface 1 d.
When the first communication pipe 11 and the second communication pipe 12 are directly connected without the arc transition surface 1d, through the above arrangement, the virtual arc transition surface 1d is formed, so that the arc length and the arc direction of the flow guiding portion 2 are equal to those of the virtual arc transition surface 1d, and when the flow guiding portion 2 guides the fluid through the flow guiding portion 2, the direction of the flow guiding portion 2 guides the fluid is equal to that of the virtual arc transition surface 1d, so that the different flow guiding portions 2 guide the fluid to enable the fluid to be distributed more uniformly on the pipe section.
