[0034] The term "plurality" used in the present application refers to two or more (including two).

[0035] In the related technology, pipelines, especially oxygen pipelines, flammable gas pipelines, and flammable liquid pipelines, have high requirements for cleanliness, but there are inevitably some fine particles in the pipelines, such as: combustible media brought in from the outside, solder residues, particles falling off the inner wall of the pipeline, etc. However, the deposition of particles will reduce the safety of pipeline use. As the amount of particle accumulation increases, the probability of combustion and explosion in the pipeline gradually increases.

[0036] Based on this, the present application proposes a pipeline component 100, which can achieve the sedimentation of particulate matter inside the pipeline component 100 to reduce the amount of particulate matter on the pipeline flow path, reduce the probability of combustion and explosion in the pipeline, reduce the safety hazards of the pipeline, and improve the safety of pipeline use.

[0037] It should be pointed out that the pipeline assembly 100 of the embodiment of the present application can be constructed as a high-purity oxygen pipeline. The high-purity oxygen pipeline has high requirements on the cleanliness of the pipeline, and there are some flammable fine particles therein. As the flammable fine particles gradually accumulate, the unsafe factors of the oxygen pipeline gradually increase. Therefore, it is necessary to design a pipeline structure that can remove or achieve the deposition of flammable particles to reduce the probability of combustion or explosion in a pure oxygen environment.

[0038] Reference below Figure 1 A pipe assembly 100 according to an embodiment of the present invention is described.

[0039] like Figure 1 As shown, the pipeline assembly 100 according to the embodiment of the present application includes: a main pipe 10, a three-way pipe 20 and a dust collecting pipe 30.

[0040] Among them, the first port 21 of the three-way pipe 20 is connected to the main pipe 10 to achieve medium conduction, the dust collecting pipe 30 is connected to the second port 22 of the three-way pipe 20, and the extension direction of the dust collecting pipe 30 is orthogonal to the medium flow direction, and is located below the main pipe 10 to precipitate particulate matter.

[0041] Specifically, the main pipe 10 extends along the flow direction of the medium in the pipeline assembly 100 (which can be a gas medium, such as oxygen, hydrogen, etc., or a liquid medium, such as gasoline, diesel, etc.), and the three-way pipe 20 has a first port 21 and a second port 22. The first port 21 and the second port 22 can have an angle. The first port 21 is connected to the main pipe 10 so that the medium in the main pipe 10 can continue to flow downstream along the flow direction after flowing through the three-way pipe 20 to achieve medium conduction. The second port 22 is connected to the dust collecting pipe 30, and the dust collecting pipe 30 is located below the main pipe 10. The extension direction of the dust collecting pipe 30 is orthogonal to the flow direction of the medium, so that during the flow of the medium, the particulate matter entrained by the medium can, under the action of gravity, settle into the dust collecting pipe 30 through the second port 22 of the three-way pipe 20 to reduce the particulate matter content in the medium flow path.

[0042] It can be understood that the lower part of the three-way pipe 20 in the medium flow path and the dust collecting pipe 30 as a whole form a particle accumulation space. The particle accumulation space is larger, the particle accumulation amount can be greater, and the accumulation effect is better. The dust collecting pipe 30 is cleaned after the particles accumulate to a certain amount, which can reduce the number of cleaning times of the dust collecting pipe 30 and improve the user experience. By reducing the particulate content in the medium flow path, the probability of combustion and explosion in the pipeline can be reduced, the safety and reliability of the pipeline assembly 100 can be improved, and safety hazards can be reduced.

[0043] That is to say, when the pipeline assembly 100 is used in a flammable environment, after the concentration of combustible particulate matter in the pipeline assembly 100 is reduced, the probability of combustion and explosion is reduced, and the safety of use is effectively improved. At the same time, the particulate matter settles in the dust collecting pipe 30, which has little impact on the medium flow path. The probability of blockage of the pipeline assembly 100 is low, and the working stability is high.

[0044] See also Figure 1 As shown, according to some embodiments of the present application, the main pipe 10 includes: a first pipe segment 11 and a second pipe segment 12, the first pipe segment 11 is connected to the first port 21, the second pipe segment 12 is connected to the third port 23 of the tee pipe 20, and the third port 23 is located downstream of the first port 21 in the medium flow direction.

[0045] Specifically, the two ends of the first pipe segment 11 are respectively formed as a first end and a second end, and the two ends of the second pipe segment 12 are respectively formed as a third end and a fourth end. On the medium flow path, the first end is located upstream of the second end, the second end is located upstream of the third end, and the third end is located upstream of the fourth end. There can be an angle between the first end and the second end, between the second end and the third end, and between the third end and the fourth end. The three-way pipe 20 has a first port 21 located upstream and a third port 23 located downstream. The second end is connected to the first port 21, and the third end is connected to the third port 23, so that the first end, the second end, the first port 21, the third port 23, the third end, and the fourth end define the medium flow path in the pipeline assembly 100, and the second port 22 and the dust collecting pipe 30 define the sedimentation path.

[0046] According to the pipeline assembly 100 of the embodiment of the present application, by arranging a three-way pipe 20 on the medium flow path, and making at least part of the pipe section of the three-way pipe 20 and the dust collecting pipe 30 define a sedimentation path, during the flow of the medium, at least part of the particulate matter entrained in the medium can be settled into the dust collecting pipe 30 under the action of gravity. On the one hand, the particulate matter content in the medium flow path can be reduced to reduce the probability of combustion, explosion, and blockage of the pipeline assembly 100, improve safety and reliability, and reduce safety hazards; on the other hand, the length of the sedimentation path is longer, the space for particulate matter accumulation is larger, the probability of the settled particulate matter being disturbed by the medium is lower, the accumulation effect and sedimentation effect are better, and the number of cleaning times can be reduced, the user experience is improved, and the cost is reduced.

[0047] exist Figure 1 In the illustrated embodiment, the pipe assembly 100 further includes a buffer tube 40 , which is disposed between the first pipe segment 11 and the first port 21 , and / or between the second pipe segment 12 and the third port 23 .

[0048] Specifically, in some embodiments, a buffer tube 40 is provided between the first pipe segment 11 and the first port 21 , and in other embodiments, a buffer tube 40 is provided between the second pipe segment 12 and the third port 23 . In a preferred embodiment, a buffer tube 40 is provided between the first pipe segment 11 and the first port 21 and between the second pipe segment 12 and the third port 23 .

[0049] It can be understood that by providing a buffer tube 40, the buffer tube 40 is located in the medium flow path, which can buffer the medium and effectively reduce the flow velocity of the medium. On the one hand, the flow velocity of the medium can be reduced to reduce the impact of the medium on the pipeline assembly 100. Smaller impact can reduce pipeline wear to reduce the number of particles and reduce the amount of particles entrained in the medium. On the other hand, the medium with a slower flow rate flows longer in the pipeline assembly 100. A longer flow time can make the sedimentation time of the particles longer, the sedimentation more complete, and the sedimentation effect better.

[0050] Furthermore, the buffer tube 40 is configured as a reducing tube or an expanding tube with a gradually changing diameter.

[0051] That is, in some embodiments, the buffer tube 40 is configured as a tube of a different diameter, and in other embodiments, the buffer tube 40 is configured as an enlarged tube with a gradually changing diameter.

[0052] Specifically, in an embodiment where the buffer tube 40 is constructed as a tube of a different diameter, the buffer tube 40 may include a plurality of sub-tube segments, such as: a first sub-tube segment, a second sub-tube segment and a third sub-tube segment, the diameters of the first sub-tube segment, the second sub-tube segment and the third sub-tube segment increase or decrease in sequence, or the diameter of the first sub-tube segment is smaller than the diameter of the third sub-tube segment, and the second sub-tube segment is constructed as a gradient tube, that is, the diameter of one end is consistent with that of the first sub-tube segment, and the diameter of the other end is consistent with that of the third sub-tube segment, and its own diameter gradually increases; in an embodiment where the buffer tube 40 is constructed as an enlarged tube, the diameter of one end of the buffer tube 40 is smaller than the diameter of the other end, and the diameter of the buffer tube 40 gradually increases in the process of extending from one end to the other end, so as to define a trumpet-shaped or conical buffer tube 40 structure.

[0053] Therefore, the medium flow rate can be reduced and the impact energy of the medium flow can be buffered through the continuous variable diameter structure or segmented variable diameter structure of the buffer tube 40, which can not only reduce the medium impact, reduce pipeline wear, and reduce the amount of particulate matter entrained in the medium, but also the slower the medium flow rate, the better the sedimentation effect.

[0054] exist Figure 1 In the illustrated embodiment, further, in the medium flow direction, the diameter of the buffer tube 40 disposed between the first tube section 11 and the first port 21 gradually increases, and the diameter of the buffer tube 40 disposed between the second tube section 12 and the third port 23 gradually decreases.

[0055] Specifically, the buffer tube 40 disposed between the first pipe section 11 and the first port 21 has a small diameter at the upstream end and a large diameter at the downstream end, and the buffer tube 40 disposed between the second pipe section 12 and the third port 23 has a large diameter at the upstream end and a small diameter at the downstream end, so as to effectively slow down the flow rate of the medium in the pipeline and improve the sedimentation effect. At the same time, under the overall flow path, the length of the area where the diameter changes is smaller, which has less impact on the layout of the pipeline assembly 100, and the layout difficulty of the pipeline assembly 100 is lower and the layout convenience is higher.

[0056] It should be pointed out that the structures of the buffer tube 40 arranged between the first pipe segment 11 and the first port 21 and the buffer tube 40 arranged between the second pipe segment 12 and the third port 23 can be the same or different. It is preferred to make the structures of the two buffer tubes 40 the same, which can reduce the mold opening cost and processing cost, and thus reduce the cost of the pipeline assembly 100.

[0057] exist Figure 1 In the illustrated embodiment, according to some embodiments of the present application, a dust collecting portion is provided at one end of the dust collecting pipe 30 away from the main pipe 10 , and the dust collecting portion is detachably provided on the dust collecting pipe 30 .

[0058] That is to say, a dust collecting part is arranged at the bottom end of the dust collecting pipe 30, and the dust collecting part is constructed as a detachable structure, so that the particulate matter accumulated inside the dust collecting pipe 30 can be cleaned by disassembling the dust collecting part, and the particulate matter in the pipe can be effectively removed. For the pipe assembly 100 for transporting flammable materials, the safety hazard of the pipe assembly 100 can be reduced, and the safety of use can be improved. At the same time, the probability of blockage of the pipe assembly 100 can also be reduced, and the working stability and reliability of the pipe assembly 100 can be improved.

[0059] It should be pointed out that the dust collecting part can be constructed as a detachable sealing cover structure, such as a flip sealing cover, a rotating sealing cover, etc.

[0060] Exemplarily, the dust collecting part may include: a flange part 31 and a flange plate 32, the flange part 31 is arranged on the dust collecting pipe 30, the flange plate 32 is detachably connected to the flange part 31, and a side surface of the flange plate 32 facing the main pipe 10 is formed as a collecting surface.

[0061] Specifically, a flange portion 31 is formed at one end of the dust collecting pipe 30 away from the main pipe 10, and the flange portion 31 is detachably connected to the flange plate 32 to realize a detachable structure of the dust collecting portion. By removing the flange plate 32, the particulate matter can be cleaned, reducing the difficulty of disassembling the dust collecting portion and improving the ease of use of the pipe assembly 100.

[0062] It should be noted that a seal may be provided between the flange 32 and the flange portion 31 to improve the sealing of the pipeline assembly 100 , reduce the probability of leakage of the pipeline assembly 100 , and improve the reliability and stability of the pipeline assembly 100 .

[0063] According to some embodiments of the present application, the pipeline assembly 100 further includes: a blocking member, which is disposed on the tee pipe 20 and / or the dust collecting pipe 30, is suitable for blocking particulate matter, and is constructed of non-combustible material.

[0064] Specifically, in some embodiments, the blocking member may be disposed in the three-way pipe 20 , and in other embodiments, the blocking member may be disposed in the dust collecting pipe 30 . In a preferred embodiment, the blocking member is disposed in the three-way pipe 20 and also in the dust collecting pipe 30 .

[0065] It should be pointed out that the blocking member can be constructed as a filtering structure or a baffle. The blocking member can be arranged between the first port 21 and the third port 23 of the three-way pipe 20 and constructed as a filtering structure to filter the particulate matter in the medium through the blocking member, increase the amount of particulate matter captured, and improve the deposition effect. The blocking member can also be arranged between the first port 21 and the second port 22 of the three-way pipe 20, or arranged in the dust collecting pipe 30, and constructed as a baffle to reduce the disturbance effect of the medium flow and enhance the particle deposition.

[0066] It can be understood that the barrier member is constructed of non-combustible material, which means that the particulate matter can be constructed of a nickel-based alloy or the like, which is a non-combustible material with high oxidation resistance.

[0067] like Figure 1 As shown, further, a pressure relief pipe 50 and a switch valve 60 are provided on the dust collecting pipe 30. The pressure relief pipe 50 is connected to the dust collecting pipe 30, and the switch valve 60 is suitable for opening to release pressure before cleaning the dust collecting part.

[0068] That is to say, before cleaning the dust collecting part, first open the switch valve 60 and release the pressure through the pressure relief pipe 50 to reduce the pressure of the system in which the pipeline assembly 100 is located to atmospheric pressure. Then, open the dust collecting part for cleaning, which can improve the safety of the pipeline assembly 100 and reduce safety hazards.

[0069] Furthermore, the pressure relief pipe 50 is arranged obliquely on the dust collecting pipe 30 , and the extending direction of the pressure relief pipe 50 has a slope of 3‰ to 5‰ compared with the extending direction of the main pipe 10 .

[0070] Exemplarily, the pressure relief pipe 50 and the main pipe 10 extend in a direction with a slope of 3‰, 4‰ or 5‰, that is, the pressure relief pipe 50 is arranged at an angle, which can reduce the probability of particulate matter in the dust collecting pipe 30 entering the pressure relief pipe 50, so as to avoid particulate matter causing damage to the sealing surface of the switch valve 60, improve the sealing reliability and stability of the branch where the pressure relief pipe 50 is located, and the inclined arrangement can enable the particulate matter in the pressure relief pipe 50 to be discharged in time, avoiding blockage of the pressure relief pipe 50.

[0071] like Figure 1 As shown, a filter screen 70 is disposed in the pressure relief pipe 50 , and the filter screen 70 is disposed adjacent to the inlet of the pressure relief pipe 50 .

[0072] Thus, the filter 70 can be used to prevent particles in the dust collecting pipe 30 from entering the pressure relief pipe 50 during the pressure relief process, thereby improving the pressure relief stability and reliability, extending the service life of the switch valve 60, and reducing the repair and maintenance costs of the pipeline assembly 100.

[0073] Further, the pressure relief pipe 50 is disposed adjacent to the inlet end of the dust collecting pipe 30 , and the pressure relief pipe 50 is disposed away from the outlet end of the dust collecting pipe 30 .

[0074] In other words, the distance between the pressure relief pipe 50 and the inlet end of the dust collecting pipe 30 is as small as possible, and the distance between the pressure relief pipe 50 and the outlet end of the dust collecting pipe 30 is as large as possible.

[0075] In this way, the volume of the accumulation space in the dust collecting pipe 30 can be increased to reduce the number of cleaning times and improve ease of use. The probability of particulate matter entering the pressure relief pipe 50 can also be reduced, thereby improving the stability and reliability of the branch where the pressure relief pipe 50 is located.
