Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, 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 in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As mentioned in the background art, in the prior art, a cold working method is generally adopted for machining the shunt hole of the shunt, but the cold working method easily causes stress concentration around the shunt hole, and further causes the problem of poor connection stability between the shunt hole and the shunt tube.

In order to solve the above problem, as shown in fig. 1, an embodiment of the present invention provides a flow divider, which includes a pipe body 10 and a cover plate 20. Wherein the tube 10 is used for circulating fluid, and the tube 10 has a fluid inlet and a fluid outlet which are communicated with each other. The cover plate 20 is arranged at the fluid outlet of the pipe body 10, a plurality of shunting holes 21 are formed in the cover plate, the shunting holes 21 are communicated with the fluid outlet, and the shunting holes 21 are processed and manufactured by adopting a hot melting drilling process. Stress around the diffluence hole can be through high temperature release in the hot melt brill course of working, and stress around the diffluence hole after the processing is comparatively dispersed, can guarantee the joint strength in diffluence hole like this, and then can make diffluence hole and shunt tubes connection stability better. The plurality of branch holes 21 are used to divide the fluid in the pipe body 10 into a plurality of streams. Alternatively, a plurality of the diversion holes 21 may be uniformly distributed on the cover plate 20, so that the fluid can be uniformly distributed to each diversion hole 21. Furthermore, the flange 22 is not arranged at the diversion hole 21 on the cover plate 20. When the shunting holes 21 are machined in the cover plate 20 by using a hot-melt drill, all materials on the cover plate 20 are cut off, and the situation that no flanging 22 exists at the shunting holes 21 is achieved. The shunt tubes 30 are welded at the shunt holes 21 of the cover plate 20.

In this embodiment, the pipe body 10 and the cap plate 20 are made of stainless steel or carbon steel. The pipe body 10 and the cover plate 20 are made of stainless steel or carbon steel, and the materials have the advantages of high structural strength, low cost and the like. Specifically, the pipe 10 and the cover plate 20 may be made of 304 stainless steel, 430 stainless steel, 316 stainless steel, cold rolled steel sheet and steel strip SPCC, hot rolled steel sheet and steel strip SPHC, Q195 carbon structural steel, Q215 carbon structural steel, Q235 carbon structural steel, or the like.

The tube 10 and the cover plate 20 are connected by brazing, and may be brazed in a furnace. The brazing seals the joint between the pipe body 10 and the cap plate 20, which ensures the joint and sealing requirements.

Specifically, the flow divider further includes a plurality of flow dividing pipes 30, and the plurality of flow dividing pipes 30 are connected with the plurality of flow dividing holes 21 in a one-to-one correspondence manner. The number of the shunt tubes 30 is generally more than 3, and the shunt tubes 30 shunt the fluid in the pipe body 10 to a plurality of pipelines. Optionally, the shunt 30 is made of TP2 phosphorous deoxidized copper or TU2 oxygen-free copper. Optionally, the shunt tubes 30 are attached to the cover plate 20 by brazing.

Further, the pipe body 10 includes a first pipe section 11, a second pipe section 12 and a third pipe section 13 connected in sequence, the second pipe section 12 has a first end and a second end which are oppositely arranged, the first end is connected with the first pipe section 11, the second end is connected with the third pipe section 13, the diameter of the first pipe section 11 is equal to that of the first end, the diameter of the third pipe section 13 is equal to that of the second end, and the diameter of the first end is smaller than that of the second end. The pressure of the fluid in the third pipe section 13 can be reduced through the design, and the pressure loss of the fluid is reduced. A cover plate 20 is arranged on the third tube section 13. A connecting pipe 40 is connected to the first pipe segment 11, and optionally, the connecting pipe 40 can be sleeved or welded on the first pipe segment 11. The adapter tube 40 is made of TP2 phosphorus deoxidized copper or TU2 oxygen-free copper.

The inner wall of the second pipe section 12 may be an inclined surface or a curved surface along the axial direction. In this way, the pressure loss of the medium during the flow in the inner cavity can be reduced, and it can be understood that if the pressure loss of the medium is too large, the dynamic pressure of the medium decreases, and the medium preferentially flows into the closest branch flow holes 21, resulting in uneven distribution of the medium flow rate. The inner wall of the second pipe section 12 is arranged to be an inclined plane along the axis direction, namely, the inner wall of the second pipe section 12 is a conical surface, and compared with the case that the inner wall of the second pipe section 12 is arranged to be an arc shape along the axis direction, the processing technology is simpler, and further the processing difficulty of the pipe body 10 is reduced.

As shown in fig. 2, a second embodiment of the present invention provides a flow divider, which is different from the first embodiment in that a flange 22 is disposed on the cover plate 20, and the flange 22 is annularly disposed on the periphery of the flow dividing hole 21. The flange 22 is formed by using a hot-melt drill to machine the branch holes 21 on the cover plate 20. The flange 22 is used for connecting the shunt tube 30, and when the flange 22 is connected with the shunt tube 30, the contact area between the cover plate 20 and the shunt tube 30 is increased, so that the connection stability of the flange 22 and the shunt tube 30 is good. Stress on the flange 22 is not concentrated too much during the process of hot-melt drilling, so that the connection strength of the flange 22 and the shunt tube 30 can be ensured.

Wherein, a transition structure is arranged between the side wall of the flanging 22 and the surface of the cover plate 20. That is, the joint between the sidewall of the flange 22 and the cover plate 20 is provided with a transition fillet 23. Therefore, the connection strength of the flanging 22 can be further improved, and the effective connection of the shunt holes 21 and the shunt tubes 30 is ensured.

As shown in fig. 3 and 4, a third embodiment of the present invention provides a flow divider, which is different from the first and second embodiments in that an included angle between a side wall of the flange 22 and a surface of the cover plate 20 is a right angle. The flanging 22 obtained by hot-melting drilling has no stress concentration between the side wall and the surface of the cover plate 20, so that rounding processing is not needed, the processing process is simplified, and the processing efficiency is improved while the connection strength is ensured.

In addition, the included angle between the side wall of the flange 22 and the surface of the cover plate 20 is a right angle, that is, the length of the flange 22 is kept at the longest state, so that the connection area between the flange 22 and the shunt tube 30 can be increased, and the connection strength between the flange 22 and the shunt tube 30 is further ensured.

According to the diverter provided by the application, the diversion holes 21 in the cover plate 20 of the diverter are processed and manufactured by adopting a hot melting drilling process, and the stress around the diversion holes 21 can be released in a high-temperature environment in the processing process, so that the stress around the diversion holes 21 is dispersed, the strength around the diversion holes 21 is better, and the connection stability between the diversion holes 21 and the diversion pipes 30 is better; the pipe body 10 and the cover plate 20 are made of stainless steel or carbon steel, and have the advantages of low processing cost, high strength and the like; the second pipe section 12 of the pipe body 10 is in a hollow truncated cone shape, so that the processing difficulty and the processing cost of the pipe body 10 are reduced.
