Description

Technical Field

[0001] This utility model relates to the field of sewer pipe technology, and in particular to a three-way vortex pipe. Background Technology

[0002] Currently, the most commonly used tee fittings are positive tee fittings, which are formed by vertically connecting a side pipe and a main pipe, with the side pipe and the main pipe connected in the middle.

[0003] The special single-pipe drainage system uses reinforced spiral pipes with raised spiral ribs on the inner wall of the main pipe. The horizontal pipe connection uses reinforced spiral pipe fittings with lateral water inlet and swirl blades, which make the water flow in the drainage riser form a wall-mounted rotating flow state and create an air core in the pipe to achieve the effect of smooth water flow.

[0004] However, this traditional structure has obvious defects in practical applications: when water flows from the side pipe into the main pipe, the turbulent water flow in the side pipe needs to be forcibly sorted by the spiral ribs to form a rotating flow state. This process causes the water flow to be subjected to excessive mechanical resistance, which not only increases the vibration amplitude of the pipeline system, but also generates significant fluid noise. Utility Model Content

[0005] In view of this, it is necessary to provide a three-way vortex tube to solve the problem of excessive resistance between the existing side tube and the main tube, which causes noise and vibration.

[0006] This utility model provides a three-way vortex tube, comprising:

[0007] The main pipe has at least one spiral ridge inside, and the spiral ridge has a recess for contacting the water flow. The recess can improve turbulence and reduce noise.

[0008] The side pipe is integrally connected to the main pipe and is in communication with the main pipe. The interior of the side pipe is provided with straight ridges extending along the length of the side pipe. The straight ridges can guide the water flow and reduce the resistance between the water flow and the main pipe.

[0009] Furthermore, at least one of the straight edges is interconnected with one of the spiral edges.

[0010] Furthermore, the diameter of the depression is less than 3 mm, and the depression is evenly distributed on both sides of the spiral ridge.

[0011] Furthermore, there are three spiral ridges, which are equidistantly spaced around the central axis of the main pipe.

[0012] Furthermore, the end of the spiral rib is integrally connected to the inner wall of the main tube.

[0013] Furthermore, the multiple straight ridges are equidistantly arranged around the central axis of the side tube.

[0014] Furthermore, the end of the straight rib is integrally connected to the inner wall of the side tube.

[0015] Furthermore, the central axis of the side tube is offset relative to the central axis of the main tube.

[0016] Furthermore, the central axis of the side tube is tangent to the spiral ridge.

[0017] Furthermore, the inner diameter of the end of the side tube furthest from the main tube is larger than the inner diameter of the end closest to the side tube.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] (1) A three-way vortex tube of this utility model is provided with a main pipe, and at least one spiral ridge is provided inside the main pipe. The spiral ridge can drive the water flow to rotate along the wall, so that a channel for gas discharge is formed in the middle of the pipe, which can reduce noise. The spiral ridge is provided with a recess that contacts the water flow. The recess structure forms a local buffer area on the surface of the spiral ridge, reducing the direct collision intensity between the water flow and the ridge, realizing a smooth transition from turbulent flow to laminar flow, which can effectively reduce fluid resistance and noise.

[0020] (2) A three-way vortex tube of the present invention is provided with a side tube, which is integrated with the main tube and internally connected. The side tube is provided with a straight ridge extending along the length direction. The straight ridge can constrain the water flow direction of the side tube, reduce turbulence when entering the main tube, promote the connection between the water flow from the side tube and the main tube, reduce impact resistance, and reduce vibration and noise.

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0030] This embodiment of a three-way vortex pipe relates to the field of sewer pipe technology. By setting a straight ridge 210 inside the side pipe 200, the water flow is pre-guided, reducing the resistance of the spiral ridge 110 driving the water flow to rotate along the wall. Furthermore, a recess 111 is set on the surface of the spiral ridge 110, which can weaken the turbulence between the water and the spiral ridge 110, reducing noise and vibration.

[0031] Please see Figures 1 to 6 This embodiment of a three-way vortex tube includes a main pipe 100 and a side pipe 200. The main pipe 100 has at least one spiral ridge 110 inside. The spiral ridge 110 can drive the water flow to rotate along the wall, forming a channel in the middle of the pipe for gas discharge, thus reducing noise. The spiral ridge 110 has a recess 111 that contacts the water flow. The recess 111 structure forms a local buffer area on the surface of the spiral ridge 110, reducing the intensity of direct collision between the water flow and the ridge, achieving a smooth transition from turbulent to laminar flow, and effectively reducing fluid resistance and noise.

[0032] The side pipe 200 is integrally connected to the main pipe 100 and internally connected. The side pipe 200 has a straight rib 210 extending along the length direction inside. The straight rib 210 can constrain the water flow direction of the side pipe 200, reduce turbulence when entering the main pipe 100, promote the connection between the water flow from the side pipe 200 and the main pipe 100, reduce impact resistance, and reduce vibration and noise.

[0033] During use, the water flow entering the side pipe 200 is divided into multiple parallel streams by the straight ribs 210 extending along the water flow direction, allowing it to smoothly enter the main pipe 100. After the water flow in the side pipe 200 is guided by the straight ribs 210, it contacts the spiral ribs 110 of the main pipe 100 in a more stable direction. The concave structure 111 of the spiral ribs 110 further absorbs the impact energy of the water flow, thereby forming a graded drag reduction mechanism.

[0034] In some embodiments, please continue reading Figures 1 to 6 At least one ridge 210 is connected to a spiral ridge 110 to form a continuous water flow guiding interface, so that the water flow in the side pipe 200 can be more smoothly integrated into the spiral flow of the main pipe 100, avoiding a surge in local resistance.

[0035] In practical implementation, the straight ridge 210 is a straight ridge extending along the length of the side pipe 200. It can be implemented using a protruding structure integrally connected to the inner wall of the side pipe 200, used to guide the water flow direction and reduce resistance when the water enters the main pipe 100. The spiral ridge 110 can be implemented using a spiral protrusion structure equidistantly distributed around the central axis of the main pipe 100, used to guide the water flow into a rotating flow pattern and improve turbulence. The connection between the straight ridge 210 and the spiral ridge 110 creates a continuous guiding surface for the water flow path between the side pipe 200 and the main pipe 100, avoiding increased resistance caused by abrupt changes in the water flow direction.

[0036] When water flows from the side pipe 200 into the main pipe 100, the straight guiding effect of the straight rib 210 and the spiral guiding effect of the spiral rib 110 combine to allow the water flow to smoothly transition along the direction of the straight rib 210 to the spiral flow channel of the spiral rib 110. This connection structure can reduce the impact and turbulence of the water flow at the confluence, reduce the frictional resistance between the water flow and the pipe wall, and at the same time weaken the vibration and noise caused by the sudden change in the direction of the water flow.

[0037] In some embodiments, please refer to Figure 2 and Figure 4 The diameter of the recess 111 is less than 3 mm. The recess 111 is evenly distributed on both sides of the spiral ridge 110. The recess 111 is in contact with the water flow, which can reduce the pressure fluctuation generated when the water flows through the spiral ridge 110 and reduce the energy loss caused by flow separation. At the same time, the symmetrically distributed recess 111 structure balances the water flow pressure on both sides and suppresses the generation of vibration noise.

[0038] In the specific implementation process, the diameter of the recess 111 is the size of the groove opening formed on the surface of the spiral ridge 110. It can be achieved by stamping or injection molding. The accuracy of the groove opening size is ensured by controlling the mold accuracy.

[0039] As water flows along the main pipe 100, the depressions 111 form localized vortex regions. Because the size of the depressions 111 is limited to a small range, with a diameter controllable to within 3 millimeters, controllable microscale turbulence is generated when the water flows into contact with the helical ridge 110. The uniformly distributed layout of the depressions 111 ensures symmetrical disturbances to the water flow on both sides of the helical ridge 110, avoiding pressure concentration on one side. This structural design maintains the guiding effect of the helical ridge 110 on the water flow while simultaneously decomposing large-scale turbulence into multiple microscale vortices through the depression 111 structure.

[0040] Compared with existing technologies, the surface of traditional spiral ridges 110 is mostly continuous and smooth, which easily forms a continuous shear layer when water flows into contact with it, resulting in a sharp increase in flow resistance. This solution decomposes the originally continuous shear flow into multiple discrete microflow states by setting regularly distributed micro-depressions 111 on the surface of the spiral ridges 110, effectively reducing the overall frictional resistance of the contact surface between the water flow and the spiral ridges 110.

[0041] In some embodiments, please refer to Figure 4 The main pipe 100 has three spiral ribs 110 inside. The three spiral ribs 110 are equidistantly arranged around the central axis of the main pipe 100. The equidistant arrangement of the three spiral ribs 110 can improve the uniformity of water flow in the main pipe 100, reduce local turbulence and noise caused by asymmetrical flow, and improve the stability of the main pipe 100 structure through the symmetrical support of the three spiral ribs 110.

[0042] In the specific implementation process, three independent spiral ridges 110 are evenly distributed circumferentially on the inner wall of the main pipe 100, and the quantity is optimized to balance the water flow distribution and structural strength. The three spiral ridges 110 are evenly distributed around the central axis at an angle of 120° to ensure the uniformity of the vortex. Specifically, the three spiral ridges 110 are distributed at equal angles along the inner wall of the main pipe 100, and the spiral angle of each spiral ridge 110 is consistent.

[0043] When the water flows into the main pipe 100, the three spiral ridges 110 simultaneously apply tangential forces to the water flow, causing the water flow to be evenly distributed along the spiral trajectory. Due to the equidistant distribution of the three spiral ridges 110, the swirling force on the water flow forms a symmetrical equilibrium in the circumferential direction, avoiding the problems of water flow deflection or local turbulence aggravation caused by a single or asymmetrical spiral ridge 110.

[0044] It should be noted that the end of the spiral rib 110 is integrally connected to the inner wall of the main pipe 100. This integral connection forms a mechanical whole between the spiral rib 110 and the main pipe 100, which can evenly distribute the load to the wall of the main pipe 100 when subjected to water flow impact, significantly improving structural reliability. The integral connection avoids increased turbulence and vibration noise caused by connection failure, while maintaining the stable guiding effect of the spiral rib 110 on the water flow, extending the service life of the tee vortex tube. The connection between the spiral rib 110 and the main pipe 100 can be achieved through integral molding or welding, eliminating connection gaps to prevent stress concentration caused by water flow impact.

[0045] In some embodiments, please refer to Figure 3 and Figure 6Multiple straight ribs 210 are equidistantly arranged around the central axis of the side pipe 200. The equidistant array of multiple straight ribs 210 can effectively reduce the water flow resistance at the connection between the side pipe 200 and the main pipe 100, reduce the vibration noise caused by water flow impact, and at the same time improve the synergistic effect of the water flow in the side pipe 200 and the spiral structure of the main pipe 100.

[0046] In the specific implementation process, the straight ribs 210 are protruding structures extending along the length of the inner wall of the side tube 200, formed by injection molding or machining, and are used to guide the water flow along the axial direction of the side tube 200. Each straight rib 210 is evenly and symmetrically distributed around the central axis of the side tube 200, which can be achieved by evenly dividing the circumferential angle, so that the water flow forms a symmetrical flow state within the side tube 200.

[0047] When water flows from the side pipe 200 into the main pipe 100, the equidistantly distributed straight ribs 210 provide uniform guidance for the water flow. The straight ribs 210 divide the water flow into multiple axially flowing branches, each branch maintaining a symmetrical distribution across the cross-section of the side pipe 200. Due to the consistent spacing of the straight ribs 210, the flow resistance within the side pipe 200 tends to be balanced, avoiding turbulence caused by excessive local velocity differences.

[0048] The existing side pipe 200 of the tee pipe lacks a guiding structure or only has asymmetrically distributed ribs, resulting in disordered impact when water flows into the main pipe 100. This solution, through the symmetrical layout of equidistant straight ribs 210, enables the water flow to form a uniform flow distribution in the side pipe 200 in advance, reducing the energy loss when the water flow comes into contact with the spiral ribs 110 of the main pipe 100.

[0049] It should be further explained that the end of the straight rib 210 is integrally connected to the inner wall of the side tube 200. This integral connection eliminates the problem of discontinuity in the end structure, avoids energy loss of water flow at the end of the straight rib 210, and enhances the impact resistance of the flow guiding structure. There are no seams or welding marks between the end of the straight rib 210 and the inner wall of the side tube 200. Specifically, the straight rib 210 and the side tube 200 can be formed in one step during the manufacturing process through mold design, avoiding structural abrupt changes at the connection.

[0050] In some embodiments, the central axis of the side pipe 200 is offset relative to the central axis of the main pipe 100, so that the water flow output from the side pipe 200 can be output relative to the edge of the main pipe 100, which has a higher degree of compatibility with the spiral rib 110. This effectively alleviates the motion interference problem between the water flow in the side pipe 200 and the spiral rib 110 inside the main pipe 100, and reduces pipe vibration and noise caused by water flow impact.

[0051] In the specific implementation process, the central axis of the side pipe 200 and the central axis of the main pipe 100 form a non-coincident spatial relationship. This can be achieved by offsetting the center of the connection port of the side pipe 200 with the center of the connection port of the main pipe 100. The offset structure can change the impact angle when the water flows into the main pipe 100 through the side pipe 200, making the water flow more closely match the rotation direction of the spiral rib 110 inside the main pipe 100.

[0052] When water flows from the side pipe 200 into the main pipe 100, its flow direction forms a matching entry angle with the spiral rise angle of the spiral rib 110 inside the main pipe 100, so that the water flow in the side pipe 200 naturally flows along the extension direction of the spiral rib 110, avoiding the turbulence caused by the water flow directly impacting the inner wall of the main pipe 100, and at the same time, the guiding effect of the spiral rib 110 is used to form a stable swirling state.

[0053] In some embodiments, please refer to Figure 5 The central axis of the side pipe 200 is tangent to the spiral ridge 110. The side pipe 200 is not only offset relative to the main pipe 100, but also inclined relative to the main pipe 100 from top to bottom, so that the main pipe 100 is tangent to the spiral ridge 110. This effectively reduces the sudden change in direction when the water flow from the side pipe 200 enters the main pipe 100, reduces the impact resistance and energy loss between the water flow and the spiral ridge 110, thereby suppressing the generation of pipe vibration and noise, and improving the swirling stability of the water flow in the main pipe 100.

[0054] In the specific implementation process, the central axis of the side tube 200 is matched with the helical helix angle of the helical ridge 110. By adjusting the connection position of the side tube 200 and the phase angle of the helical ridge 110, the axis of the side tube 200 and the tangent direction of the helical ridge 110 at the connection point can be made to coincide.

[0055] When the side pipe 200 is connected to the main pipe 100, the central axis of the side pipe 200 is tangential to the spiral trajectory of the spiral ridge 110. After the water flows from the side pipe 200 into the main pipe 100, its flow direction is consistent with the tangential direction of the spiral ridge 110, allowing the water to move directly along the guiding direction of the spiral ridge 110, avoiding turbulence and increased local resistance caused by the angle between the water flow direction and the spiral ridge 110.

[0056] In some embodiments, the inner diameter of the end of the side pipe 200 away from the main pipe 100 is larger than the inner diameter of the end closer to the side pipe 200. The use of a tapered side pipe 200 optimizes the water flow transmission path from the side pipe 200 to the main pipe 100, reducing the concentrated release of turbulent energy at the pipe wall interface. The laminar flow effect generated by the tapered channel can reduce turbulent noise when the water flow comes into contact with the helical ridge 110.

[0057] As water flows from the inlet of the side pipe 200 to its connection with the main pipe 100, the gradually narrowing inner diameter structure increases the flow velocity and creates laminar flow. This tapering channel design allows the water to complete kinetic energy conversion before entering the main pipe 100, effectively reducing turbulence intensity when the water comes into contact with the spiral ridge 110. In the area where the side pipe 200 and the main pipe 100 meet, the directional increase in flow velocity helps overcome the rotational resistance formed by the spiral ridge 110, while the widening inlet structure buffers the impact of the water flow on the inner wall of the main pipe 100.

[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the present utility model.
