Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.
The utility model provides a pipeline connection structure, including body 10, coupling 20, 40 is taken over to closing cap 30 and a plurality of son, regard alone with body 10, body 10 has the inner chamber, the relative both ends of inner chamber have little opening and big opening respectively, little open-ended flow area is less than big open-ended flow area, coupling 20 and little opening intercommunication, at least part setting of closing cap 30 is in big opening department, can seal the setting between the outer peripheral face of closing cap 30 and the inner wall of body 10, closing cap 30 has a plurality of connecting holes 31 all with the inner chamber intercommunication, 40 and a plurality of connecting holes 31 one-to-one intercommunication are taken over to a plurality of son, the flow area of son takeover 40 is less than little open-ended flow area. In the present embodiment, the body 10 and the pipe joint 20 are integrally formed, but as another embodiment, the body 10 and the pipe joint 20 may be formed as separate members.
In the scheme, the body 10 is provided with an inner cavity, the pipe joint 20 and the sub-connecting pipe 40 are respectively communicated with two ends of the inner cavity, so that fluid enters the inner cavity no matter the fluid enters from the pipe joint 20 or enters from the sub-connecting pipe 40, the fluid is mixed in the inner cavity and then is output from the sub-connecting pipe 40 or the pipe joint 20, the output fluid is mixed uniformly, and the separation or flow collection effect is improved.
As shown in fig. 1 to 4, in the first embodiment, the body 10 includes a connecting cylinder section 12, a transition cylinder section 13 and a bottom wall 14 which are connected in sequence, the connecting cylinder section 12 is connected with the sealing cover 30, the inner surface of the transition cylinder section 13 is a curved surface, and the small opening is located on the bottom wall 14; wherein the area between the closure cap 30, the transition barrel section 13 and the bottom wall 14 forms the mixing chamber 11. This provides a better mixing of the fluid after it has entered the mixing chamber 11.
For example, the pipe connection structure is used as a flow divider, the refrigerant containing gas and liquid enters the mixing cavity 11 from the pipe joint 20, most of the refrigerant enters the mixing cavity 11 and then contacts the sealing cover 30, the sealing cover 30 blocks the flow of the refrigerant, the refrigerant flows toward the bottom wall 14 after being reflected by the sealing cover 30, and then the refrigerant is finally output through the sub-connecting pipes 40 after being reflected by the bottom wall 14. The refrigerant that gets into from coupling 20 in this scheme can directly not be followed the sub-output of taking over 40 promptly, gaseous state and liquid refrigerant get into behind the hybrid chamber 11 can collide with the inner wall of hybrid chamber 11, and the refrigerant is through reflection reverse flow to realized gaseous state and liquid refrigerant's intensive mixing, the refrigerant redistribution after the mixture is taken over 40 outputs to a plurality of subsumps. Therefore, the scheme realizes the sufficient mixing of the refrigerants, ensures the uniformity of the refrigerants distributed to different sub-connecting pipes 40 and improves the distribution effect.
As shown in FIG. 3, the body 10 is a solid of revolution, the included angle between the inner surface of the bottom wall 14 and the axis of the body 10 is A, and A is greater than or equal to 80 degrees and less than or equal to 100 degrees. Defining the angle between the inner surface of the bottom wall 14 and the axis of the body 10 in the above range provides a better blocking and reflecting effect of the bottom wall 14 for the fluid reflected from the cap 30, thereby facilitating thorough mixing of the fluid.
Specifically, the cover 30 has a plate-like structure, so that the fluid introduced from the pipe joint 20 has a better collision and reflection effect after contacting the cover 30.

Wherein, along the axial direction of the sealing cover 30, the end surface of the sealing cover 30 close to the bottom wall 14 is a lower end surface. If the distance L between the cover 30 and the bottom wall 14 is too large, the reflected fluid flow path is too long, the flow velocity is reduced during the flow, and the re-collision and reflection velocities are reduced, which affects the mixing effect, so that the distance between the cover 30 and the bottom wall 14 is limited to the above range to ensure the mixing effect of the fluid in the mixing chamber 11. The minimum distance between the lower end face of the cover 30 and the inner wall of the bottom wall 14, i.e. the minimum value of L, is set according to the use requirements, for example, 2mm, 4mm.

With the above arrangement, the sub-adapter 40 and the pipe connector 20 are offset on the projection plane perpendicular to the sub-adapter 40 (which can also be understood as the radial direction of the sub-adapter 40), so that the fluid entering from the pipe connector 20 is prevented from being directly conveyed to the sub-adapter 40, and most of the fluid entering from the pipe connector 20 needs to collide with the inner wall of the mixing chamber 11 for reflection before being conveyed to the sub-adapter 40, so that the fluid is mixed.
To further improve the mixing and splitting effect, the sub-connector 40 and the connector 20 may be completely radially offset, which increases the resistance to fluid flow. The actual offset range of the sub-adapter 40 and the pipe joint 20 is set according to the use situation.

The number of the sub-nipples 40 may be set to two, three, four, etc., as needed. The plurality of sub-nozzles 40 may not be uniformly distributed along the central circle, and the specific arrangement mode is set according to the use condition.
