Technical Field
[0001] This invention relates to the field of five-way connector technology, and more particularly to a five-way connector that facilitates flow adjustment. Background Technology
[0002] Five-way connectors are commonly used pipe fittings in fluid transportation and flow control. They are mainly used in water supply, HVAC, hydraulic transmission, and cooling circulation systems to evenly distribute one main fluid to four branch lines, achieving centralized fluid input and multi-way output. Traditional five-way connectors mostly adopt a one-piece cast structure, consisting of one main inlet and four evenly distributed outlets. The internal flow channels are fixed, and the structure is simple. During installation, they are directly welded or threaded to the pipe. Flow distribution relies on the fixed internal orifice diameter, and it is impossible to actively control the flow rate or on / off status. They are fixed, non-adjustable flow distribution connectors, and their applicability is poor in scenarios requiring multi-way on-demand water supply, branch flow restriction, and on / off switching.
[0003] Conventional five-way fittings have some shortcomings in practical use and cannot meet the flexible application requirements of modern piping systems:
[0004] On the one hand, conventional five-way connectors generally adopt a one-piece molded structure, which is not easy to disassemble. When there is blockage, wear, leakage or partial damage inside, it is impossible to disassemble, repair, clean or replace the damaged parts separately. The entire connector can only be scrapped and replaced, resulting in high maintenance costs and serious waste of resources. At the same time, installation and disassembly are quite difficult.
[0005] On the other hand, the internal flow channel has a fixed diameter structure, and the outflow rate is a fixed value, which cannot be adjusted or controlled. It cannot achieve complete closure or full opening, nor can it individually limit and adjust the flow of each branch. It cannot allocate the flow according to the actual use scenario, thus limiting the use scenarios and limiting the function. Summary of the Invention
[0006] In view of the shortcomings of the prior art, the present invention provides a five-way connector that is easy to adjust the flow rate, which overcomes the shortcomings of the prior art and effectively solves the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A five-way connector that facilitates flow adjustment includes a square connector base, wherein a main inlet is welded through one outer wall of the square connector base, and secondary outlets are provided on all four outer walls of the square connector base.
[0009] The main inlet pipe is located at one end of the main inlet head inside the square connector seat. A rectangular frame is welded around the outer wall of the main inlet pipe. An outlet pipe is welded to the end of the rectangular frame away from the main inlet pipe. A sealing disc is slidably installed inside the main inlet pipe. A telescopic column is welded to the center of one side of the outer wall of the sealing disc. A water flow regulating cover is fixedly connected to the outer wall of the telescopic column by screws. An internally threaded pipe is installed through the periphery of one side of the outer wall of the water flow regulating cover at equal intervals. A threaded rod is screwed onto the inner wall of the internally threaded pipe. A sealing plate is rotatably connected to the outer wall of one end of the threaded rod. The sealing plate is tightly attached to the inner wall of the rectangular frame.
[0010] Preferably, the auxiliary connector includes a connecting plate, a positioning plate, and a connector outlet. The connecting plate is fixedly connected to the outer wall of the square connector seat by screws, the positioning plate is welded to the center of one side of the outer wall of the connecting plate, and the connector outlet is welded to the center of the other side of the outer wall of the connecting plate.
[0011] Preferably, the square connector seat has positioning grooves on all four outer walls, and the size of the positioning grooves is adapted to the size of the positioning plate.
[0012] Preferably, the water flow regulating cover includes a guide cover, a water flow closed limiting plate, and a water flow fully open limiting plate. The guide cover is disposed through the inner wall of the other side of the square connector seat. The water flow closed limiting plate and the water flow fully open limiting plate are respectively fixedly connected to the outer walls of the two sides of the guide cover. The guide cover and the square connector seat are interference-fitted. The water flow closed limiting plate is located outside the square connector seat, and the water flow fully open limiting plate is located inside the square connector seat.
[0013] Preferably, a flow rate scale bar is rotatably connected to the outer wall of one end of the lead screw, and the flow rate scale bar is slidably disposed on the inner wall of the water flow regulating cover.
[0014] Preferably, a main sealing cover is welded to the outer wall of one end of the main inlet pipe, and the main sealing cover is wrapped around the outer wall of one end of the main inlet head; a secondary sealing cover is welded to the outer wall of one end of the outlet pipe, and the secondary sealing cover is wrapped around the outer wall of one end of the secondary outlet head.
[0015] Preferably, a circular sealing ring is embedded in the inner wall of the other end of the main inlet pipe, and a telescopic column is disposed through the inner wall of the circular sealing ring. A rectangular sealing ring is embedded in the inner wall of one end of the rectangular frame, and a sealing plate is disposed through the inner wall of the rectangular sealing ring.
[0016] Preferably, a tie rod is welded to the outer wall of the end of the telescopic column away from the sealing disc.
[0017] The beneficial effects of this invention are as follows:
[0018] 1. The five-way connector of the present invention, which facilitates flow adjustment, achieves the dual functions of detachable assembly and maintenance and three-stage flow adjustment through the overall mechanical cooperation of square connector seat, main inlet, detachable secondary outlet, sealing plate, water flow adjustment cover, screw and sealing plate. The overall structure is reasonably designed and the operation is simple and convenient, which can fundamentally solve the core problems of traditional five-way connectors that are integrated and cannot be disassembled and whose flow cannot be adjusted.
[0019] 2. The five-way connector of the present invention, which facilitates flow adjustment, uses a detachable connection structure between a square connector seat and an auxiliary connector outlet. It is precisely positioned with a positioning plate and a positioning groove, and the connecting plate is tightened with screws.

It can freely control the main on / off state and the flow rate of each branch, adapt to various scenarios, and achieve precise fluid distribution. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0032] Reference Figures 1-9 Example 1: A five-way connector that facilitates flow adjustment includes a square connector base 1. A main inlet 2 is welded through one outer wall of the square connector base 1, and secondary outlets 3 are provided on all four outer walls of the square connector base 1. Each secondary outlet 3 includes a connecting plate 31, a positioning plate 32, and an outlet 33. The connecting plate 31 is fixedly connected to the outer wall of the square connector base 1 by screws. The positioning plate 32 is welded to the center of one outer wall of the connecting plate 31, and the outlet 33 is welded to the center of the other outer wall of the connecting plate 31.
[0033] Through the above scheme, the square connector seat 1 serves as the overall support base, providing installation space for the internal flow channel and adjustment mechanism. The main inlet 2 is used for the input of the external main body and is the only channel for fluid to enter the connector. The auxiliary outlet 3 realizes the diversion and output of four fluids to meet the needs of multiple water supply. The connecting plate 31 is connected by screws for quick disassembly and replacement of the auxiliary outlet 3. The positioning plate 32 cooperates with the square connector seat 1 to ensure that the auxiliary outlet 3 is installed in a precise position with high concentricity, preventing displacement and leakage. The outlet 33 is used to connect with external pipelines to form a complete fluid output channel.
[0034] In this embodiment, the detachable connection structure between the square connector seat 1 and the auxiliary connector 3, combined with the precise positioning of the positioning plate 32 and the positioning groove 19, and the screw fastening of the connecting plate 31, enables quick disassembly and assembly, partial replacement, and internal cleaning without the need for complete scrapping. This reduces maintenance costs and improves the convenience of installation and maintenance.
[0035] In embodiment 2, a main inlet pipe 4 is provided inside the square connector seat 1 at one end of the main inlet head 2, and a rectangular frame 5 is welded around the outer wall of the main inlet pipe 4. An outlet pipe 6 is welded to the end of the rectangular frame 5 away from the main inlet pipe 4. A sealing plate 7 is slidably provided inside the main inlet pipe 4, and a telescopic column 8 is welded to the center of the outer wall of one side of the sealing plate 7. A water flow regulating cover 9 is fixedly connected to the outer wall of the telescopic column 8 by screws. An internally threaded pipe 10 is installed through the periphery of the outer wall of one side of the water flow regulating cover 9. A threaded rod 11 is screwed to the inner wall of the internally threaded pipe 10, and a sealing plate 12 is rotatably connected to the outer wall of one end of the threaded rod 11. The sealing plate 12 is tightly attached to the inner wall of the rectangular frame 5.
[0036] Through the above scheme, the main inlet pipe 4 is used to collect and stably transport the fluid from the main inlet head 2, providing a uniform pressure environment for the surrounding diversion. The rectangular frame 5 serves as the diversion channel between the main inlet pipe 4 and the outlet pipe 6, providing a uniform four-way diversion path for the fluid and ensuring balanced flow in each branch. The outlet pipe 6 guides the diverted fluid to the secondary outlet head 3, completing the fluid distribution.
[0037] The sealing disc 7 slides inside the main inlet pipe 4 to control whether the main fluid enters the rectangular frame 5, thus achieving overall on / off control. The telescopic column 8, as a transmission component, transmits external pulling force to the sealing disc 7, causing the sealing disc 7 to move synchronously, achieving switching between fully closed and fully open states. The water flow regulating cover 9 guides and limits the telescopic column 8, ensuring a stable and smooth adjustment process. The internal threaded pipe 10 provides threaded support for the lead screw 11, enabling the lead screw 11 to generate axial displacement when rotating. The lead screw 11 converts rotational motion into linear motion, driving the sealing plate 12 to move smoothly. The sealing plate 12 slides tightly against the inner wall of the rectangular frame 5, changing the effective flow area within the rectangular frame 5, thus achieving fine stepless adjustment of the flow rate of each branch, thereby meeting different flow requirements.
[0038] In this embodiment, through the coordinated operation of the main inlet pipe 4, rectangular frame 5, sealing disc 7, water flow regulating cover 9, internal threaded pipe 10, screw 11, and sealing plate 12, three adjustment modes are achieved: fully enclosed, fully open, and branch stepless flow limiting. The main on / off state and the flow rate of each branch can be freely controlled, adapting to various scenarios and achieving precise fluid distribution.
[0039] The square connector 1 has positioning grooves 19 on all four outer walls, and the size of the positioning grooves 19 is adapted to the size of the positioning plate 32.
[0040] Through the above scheme, the positioning groove 19 and the positioning plate 32 form a precise positioning fit, which restricts the radial offset and rotation of the auxiliary connector 3, ensures the concentricity of the installation, improves the connection sealing and structural stability, and prevents loosening and leakage during use.
[0041] The water flow regulating cover 9 includes a guide cover 91, a water flow closed limiting plate 92, and a water flow fully open limiting plate 93. The guide cover 91 is disposed through the inner wall of the other side of the square connector seat 1. The water flow closed limiting plate 92 and the water flow fully open limiting plate 93 are respectively fixedly connected to the outer walls of the two sides of the guide cover 91. The guide cover 91 and the square connector seat 1 are interference-fitted. The water flow closed limiting plate 92 is located outside the square connector seat 1, and the water flow fully open limiting plate 93 is located inside the square connector seat 1.
[0042] Through the above scheme, the guide cover 91 provides sliding guidance for the telescopic column 8, ensuring that the telescopic column 8 and the sealing plate 7 do not move eccentrically or get stuck. The water flow closed limit plate 92 and the water flow fully open limit plate 93 form a dual mechanical limit, clearly marking the fully closed position and the fully open position, avoiding excessive adjustment that could cause structural damage, and improving operational accuracy and safety.
[0043] A flow rate scale bar 13 is rotatably connected to the outer wall of one end of the lead screw 11, and the flow rate scale bar 13 is slidably disposed on the inner wall of the water flow regulating cover 9.
[0044] With the above scheme, the flow scale bar 13 moves synchronously with the lead screw 11, intuitively displaying the position and opening of the sealing plate 12, realizing quantitative adjustment of flow, improving adjustment accuracy, and meeting the needs of precise flow control.
[0045] A main sealing cover 14 is welded to the outer wall of one end of the main inlet pipe 4, and the main sealing cover 14 is wrapped around the outer wall of one end of the main inlet head 2. A secondary sealing cover 15 is welded to the outer wall of one end of the outlet pipe 6, and the secondary sealing cover 15 is wrapped around the outer wall of one end of the secondary outlet head 3.
[0046] Through the above scheme, the main sealing cover 14 strengthens the seal between the main inlet pipe 4 and the main inlet head 2, and the secondary sealing cover 15 strengthens the seal between the outlet pipe 6 and the secondary outlet head 3. The double sealing structure prevents fluid leakage during transportation and ensures the overall sealing performance of the joint.
[0047] A circular sealing ring 16 is embedded in the inner wall of the other end of the main inlet pipe 4, and the telescopic column 8 is installed through the inner wall of the circular sealing ring 16. A rectangular sealing ring 17 is embedded in the inner wall of one end of the rectangular frame 5, and the sealing plate 12 is installed through the inner wall of the rectangular sealing ring 17.
[0048] Through the above scheme, the circular sealing ring 16 forms a sliding seal on the telescopic column 8, which maintains the seal during the movement of the telescopic column 8, preventing fluid leakage from the end of the main inlet pipe 4. The rectangular sealing ring 17 forms a sliding seal on the sealing plate 12, ensuring that the sealing plate 12 does not leak internally when adjusting the flow rate, thus improving the reliability of the seal.
[0049] A tie rod 18 is welded to the outer wall of the end of the telescopic column 8 away from the sealing plate 7.
[0050] Through the above solution, the pull rod 18 provides a convenient force point, making it easy for operators to manually pull the telescopic column 8 to quickly switch the position of the sealing plate 7, and complete the rapid conversion between fully enclosed and fully open modes. The operation is simple, labor-saving and efficient.
[0051] Working principle: The fluid enters the main inlet pipe 4 inside the square connector seat 1 from the main inlet 2. The flow rate is adjusted in three modes: The first mode is the fully enclosed mode. Pushing the pull rod 18 inward will move the telescopic column 8 and the sealing plate 7, so that the sealing plate 7 completely blocks the channel between the main inlet pipe 4 and the rectangular frame 5. The fluid cannot enter the diversion area, and no water flows out of the four auxiliary outlets 3, thus achieving overall flow interruption.
[0052] The second type is the fully open mode. Pull the lever 18 outward to drive the telescopic column 8 and the sealing plate 7 to move outward synchronously until the water flow fully open limit plate 93 fits against the square connector seat 1. At this time, the sealing plate 7 is completely away from the channel between the main inlet pipe 4 and the rectangular frame 5. The fluid enters the four rectangular frames 5 evenly, and then flows through the outlet pipe 6 to the auxiliary connector 3, realizing the maximum output of all four flow paths.
[0053] The third type is the branch-arbitrary adjustment mode. Based on the fully open mode, the four lead screws 11 are rotated respectively. The lead screws 11 rotate in the internal threaded pipe 10 and generate axial movement, which drives the sealing plate 12 to slide along the inner wall of the rectangular frame 5, changing the effective flow cross-sectional area in the rectangular frame 5, thereby freely controlling the flow rate of each branch. The flow scale bar 13 moves synchronously to display the opening degree, which can realize stepless precise adjustment from fully closed to fully open.
[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
