Description

Technical Field

[0001] The utility model belongs to the technical field of liquid circulation, in particular to a liquid internal circulation pipeline mechanism. Background Art

[0002] Generally, liquid circulation on the market is achieved by forming a loop through a dual-channel pipeline (i.e., a dual-pipe system with one supply and one return) or by adding a return path at the end of the pipeline. The dual-channel pipeline method is not suitable for situations where one pipeline has been laid and the other pipeline is not available for construction; and the method of adding a return path at the end of the pipeline requires the original end of the pipeline to be modified. There is a lack of a device on the market that is applicable to existing pipelines and can achieve internal circulation of liquid without modifying the pipeline.

[0003] In view of this, a liquid internal circulation pipeline mechanism is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a liquid internal circulation pipeline mechanism in order to solve the above-mentioned problems.

[0005] The technical solution adopted by the utility model is as follows: it includes a main pipeline, a secondary pipeline and a water pump, the secondary pipeline includes a first pipe section and a second pipe section, the tail end of the second pipe section extends to the inner end of the main pipeline, the head and tail ends of the first pipe section are respectively connected to the inlet side of the main pipeline and the head end of the second pipe section, thereby forming an internal liquid circulation passage, and the water pump is arranged at the connection between the first pipe section and the second pipe section.

[0006] In a preferred embodiment, the water pump is placed inside or outside the main pipe. If the water pump is placed outside the main pipe, the first pipe section is placed at the outer end of the main pipe, and the head end of the second pipe section extends out of the main pipe.

[0007] In a preferred embodiment, the tail end of the first pipe section and the head end of the second pipe section are both provided with connecting flanges.

[0008] In a preferred embodiment, the diameter of the secondary pipe is smaller than the diameter of the primary pipe.

[0009] To sum up, due to the adoption of the above-mentioned technical scheme, the beneficial effects of the utility model are as follows: a smaller pipe with a water pump is reserved at the inlet of the pipe, and the tail end of the smaller pipe is extended to the end of the pipe to form an internal circulation passage for the liquid, and a water pump is added to the smaller pipe, and the water pump is used to provide power for the liquid circulation, thereby realizing the internal circulation operation of the liquid. The overall method of use is simple, and there is no need to increase the loop pipe or modify the pipe, which saves the overall cost. At the same time, the overall application scenarios are wide, and it can be widely applied to various existing pipes, which is worthy of promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0014] Embodiment 1:

[0015] Reference Figure 1-Figure 2 A liquid internal circulation pipeline mechanism includes a main pipeline 1, a secondary pipeline 3 and a water pump 2. The secondary pipeline 3 includes a first pipe section 301 and a second pipe section 302. The tail end of the second pipe section 302 extends to the inner end of the main pipeline 1. The head and tail ends of the first pipe section 301 are respectively connected with the inlet side of the main pipeline 1 and the head end of the second pipe section 302, thereby forming a liquid internal circulation passage. The water pump 2 is arranged at the connection between the second pipe section 302 and the first pipe section 301. The secondary pipeline 3 is reserved at the inlet of the main pipeline 1. At the same time, the tail end of the secondary pipeline 3 is extended to the end of the main pipeline 1 to form a liquid internal circulation passage. The water pump 2 is added to the secondary pipeline 3, and the water pump 2 is used to provide power for liquid circulation, so that the liquid internal circulation operation can be realized. The overall use method is simple, and there is no need to increase the loop pipeline or modify the pipeline, which saves the overall cost. At the same time, the overall application scenario is wide, and it can be widely applied to various existing pipelines.

[0016] Among them, valves, water pressure gauges, etc. can also be additionally added to the secondary pipeline 3 according to different application scenarios, which will not be elaborated in detail here.

[0017] Furthermore, the water pump 2 is placed inside or outside the main pipeline 1. If the water pump 2 is placed outside the main pipeline 1, the first pipe section 301 is placed at the outer end of the main pipeline 1, and the head end of the second pipe section 302 extends out of the main pipeline 1. When the transported liquid is corrosive or has an impact on the water pump 2, the water pump 2 can be designed outside the main pipeline 1 to avoid the liquid from affecting the water pump 2; when the transported liquid has little impact on the water pump 2 or has requirements for sealing, the water pump 2 can be placed in the main pipeline 1, so that the secondary pipeline 3 is accommodated in the main pipeline 1 as a whole, which can reduce the overall size and prevent liquid leakage.

[0018] Among them, mounting holes for fixing the water pump 2 can be reserved on the inner and outer sides of the main pipeline 1 respectively, and the portion of the main pipeline 1 can be thickened at the location of the mounting holes.

[0019] Furthermore, the tail end of the first pipe section 301 and the head end of the second pipe section 302 are both provided with connection flanges, and can be combined with the water pump 2 through the connection flanges.

[0020] Furthermore, the diameter of the secondary pipe 3 is smaller than the diameter of the main pipe 1 , and the above design can avoid affecting the passage of liquid in the main pipe 1 .

[0021] The main pipeline 1 and the auxiliary pipeline 3 are fixed by welding or integrally formed to prevent liquid from leaking from the connection between the main pipeline 1 and the auxiliary pipeline 3 .

[0022] Embodiment 2:

[0023] The difference between Example 2 and Example 1 is that when the water pump 2 is placed in the main pipeline 1, the secondary pipeline 3 can also be only a single pipe section, that is, the first pipe section 301 is omitted, and the water inlet of the water pump 2 can be placed inside the inlet side of the main pipeline 1, and the liquid can directly enter through the water inlet of the water pump 2 to achieve reciprocating circulation of the liquid.

[0024] Embodiment 3: The difference between Embodiment 3 and Embodiment 1 is that when the water pump 2 is placed outside the main pipeline 1, the secondary pipeline 3 may also be only a single pipe section, that is, the first pipe section 301 is omitted, that is, a water outlet with a flange is provided on the pipe wall on the inlet side of the main pipeline 1, and the water inlet of the water pump 2 can be connected to the water outlet of the main pipeline 1 through the flange, thereby realizing the reciprocating circulation of the liquid.

[0025] To sum up, a smaller pipe with a water pump is reserved at the pipe inlet, and the tail end of the smaller pipe is extended to the end of the main pipe 1 to form an internal liquid circulation passage. There is no need to add a loop pipe or modify the pipe, which saves the overall cost. At the same time, the overall application scenarios are wide, and it can be widely applied to various existing pipes, which is worthy of promotion.
