Description

Technical Field

[0001] This utility model relates to the field of pipe workpiece technology, and in particular to a multifunctional tee connector. Background Technology

[0002] According to Chinese Publication No. CN207145845U, a quick-release tee pipe includes: a tee pipe body, a push ring, a locking ring, and a clamping ring with a pressing edge at one end. The two straight-through end interfaces of the tee pipe body have a grooved structure, and the branch end interface has a socket structure. The locking ring, push ring, and clamping ring are arranged sequentially from the inside to the outside at the branch end interface of the tee pipe body. The inner surface and outer surface of the push ring are conical and cylindrical, respectively, and the inner surface and outer surface of the locking ring are cylindrical and conical, respectively. The outer surface matches the inner surface of the push ring. The inner surface of the clamping ring is threaded to the outer wall of the socket end interface of the tee pipe body. This utility model is easy to install and disassemble, suitable for pipes that are repeatedly disassembled, and can effectively improve the installation accuracy and efficiency of the pipe.

[0003] The aforementioned patent documents and prior art have the following technical problems:

[0004] 1. Traditional pipe connection filter devices mostly use a fixed single-piece filter screen structure. This structure has the drawback of limited filtration area. During long-term or high-flow fluid filtration, impurities can easily accumulate on the filter screen surface, causing the filter screen to become clogged. This leads to a sharp increase in fluid resistance, affecting the flow and pressure balance of the entire pipeline system, and may even cause the pipeline system to shut down. Moreover, when the filter screen needs to be cleaned or replaced, due to its fixed installation method, it is often necessary to disassemble a large number of related parts. The operation is complicated, time-consuming and labor-intensive, which greatly increases maintenance costs and downtime, and reduces production efficiency.

[0005] 2. Existing tee connectors have shortcomings in fluid guidance. At the pipe connection point, fluid is prone to accumulation due to changes in flow direction. Especially under different flow rate and velocity conditions, it is impossible to effectively guide the fluid to flow quickly and evenly. This will lead to a large pressure loss of fluid in the pipe and low power transmission efficiency, which will affect the conveying capacity of the entire pipeline system. At the same time, the unstable flow of fluid may also cause pipe vibration, noise and other problems. In the long run, it will damage the connection stability and service life of the pipeline, increase the safety hazards and maintenance costs of system operation. Utility Model Content

[0006] The purpose of this invention is to solve the shortcomings of existing technologies, such as the difficulty in replacing and adjusting the internal filter of the three-way pipe and the easy accumulation of flow inside the three-way pipe, and to propose a multifunctional three-way connector.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional tee connector, including a tee bend, wherein the inner wall of the tee bend is provided with an installation thread near the top, a filter assembly is provided inside the tee bend, and a flow guide ball assembly is provided at the joint position inside the tee bend. The filter assembly includes a first filter disc and a second filter disc, the vertical central axes of the first filter disc and the second filter disc coincide with each other, a positioning screw hole is opened on the surface of the tee bend, a positioning bolt is provided inside the positioning screw hole, and the bottom end of the positioning bolt engages with the top surface of the filter assembly.

[0008] Preferably, a limiting groove is formed on the surface at the intersection of the first filter disc and the second filter disc, and a limiting block is provided on the bottom surface of the positioning bolt, with the limiting block and the limiting groove being in clearance fit.

[0009] Preferably, the top surface of the limiting block has a regular polygonal cross-section, and the endpoints of the adjacent sides of the limiting block are located at the edge of the positioning bolt.

[0010] Preferably, the flow guide assembly includes a central sphere body and conical helical blades, wherein the conical helical blades are evenly distributed on the surface of the central sphere body.

[0011] Preferably, the flow guide ball assembly engages with the inner wall of the tee bend pipe at the connection point, and the end of the conical spiral blade closest to the central ball body is the end with a smaller diameter.

[0012] Preferably, the first filter disc and the second filter disc are the same size, and the outer edge of the first filter disc abuts against the inner wall of the tee bend.

[0013] Preferably, a sealing seat is provided inside the tee bend near the installation thread position, and the surface of the sealing seat is fitted with sealant.

[0014] Beneficial effects

[0015] This invention employs a filter assembly located near the port of a three-way bend to filter impurities in the fluid. This differs from the traditional fixed single-piece filter structure. Instead, it utilizes a first and second filter disc, which are perpendicularly overlapped and installed. Positioning and rotation adjustment are achieved via positioning bolts. When the first filter disc has a high level of impurities, the filter assembly can be rotated using the positioning bolts to switch to the second filter disc for filtration. This significantly reduces downtime for maintenance, improves production and operational efficiency, and lowers maintenance costs. Furthermore, it allows for the capture of more impurity particles within the same filtration time and fluid flow rate, effectively improving filtration efficiency and accuracy. This ensures the purity of the fluid during subsequent pipeline transmission, reduces pipe blockage and equipment wear caused by impurities, and extends the service life of the entire pipeline system and related equipment.

[0016] In this invention, a flow guide ball assembly is installed at the pipe junctions in three directions inside a three-way bend. The central ball has evenly distributed conical spiral blades on its surface. Upon impact from the incoming liquid, the entire flow guide ball assembly rapidly rotates and vibrates. This rotational motion, combined with the special shape of the conical spiral blades, cleverly alters the fluid flow pattern, guiding the fluid, which might otherwise flow in a straight line or randomly, into a vortex. The formation of this vortex flow effectively breaks the accumulation phenomenon that easily occurs at pipe junctions, allowing the fluid to be transmitted more evenly and smoothly within the three-way bend and subsequent pipes. This not only reduces pressure loss during fluid flow and improves the dynamic efficiency of fluid transmission, but also ensures that the fluid can stably undergo diversion or merging operations through the three-way connector under different flow rate and velocity conditions. It avoids pipe vibration and noise problems caused by poor fluid flow, improving the stability and reliability of the entire pipeline system. It is particularly suitable for industrial production and chemical fluid transportation fields where high fluid transmission efficiency and stability are required. Attached Figure Description

[0025] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0028] Reference Figure 1-6 A multifunctional tee connector includes a tee bend 1. The inner wall of the tee bend 1 has an installation thread 2 near its top. The tee bend 1, as the main structure of the connector, provides a fluid flow channel, allowing three pipes in different directions to be connected together, enabling fluid diversion or merging. Its internal space allows fluid to flow between pipes in different directions. The installation thread 2 on the inner wall is used to connect other components, such as a sealing seat 3, to ensure a tight and airtight connection. Fluid flows in from one port of the tee bend 1 and can flow to the other two ports as needed. During this process, it interacts with the internal filter assembly 5 and flow guide ball assembly 6, providing a stable connection framework and fluid channel foundation. This allows the multifunctional tee connector to function in various piping systems and meet complex fluid transmission requirements.

[0029] The T-bend 1 houses a filter assembly 5, and a flow guide ball assembly 6 is located at the junction of the T-bend 1. The filter assembly 5 includes a first filter disc 501 and a second filter disc 502. The vertical central axes of the first filter disc 501 and the second filter disc 502 coincide. The first filter disc 501 and the second filter disc 502 filter the fluid passing through the T-bend 1, removing solid particles and other impurities to prevent them from entering the subsequent piping system and causing blockages or damage to the equipment. When the fluid flows through the filter discs, impurities are blocked on the disc surface. Because the first filter disc 501 and the second filter disc 502 overlap perpendicularly, the filtration area and the stability of the filtration effect are increased. During normal operation, the fluid first passes through one of the filter discs for preliminary filtration. When the surface of that disc has a large amount of impurities, causing a decrease in filtration efficiency, it can be switched to the other filter disc by rotating the positioning bolt 503. This changes the traditional fixed single-piece filter structure, improves the reliability and durability of filtration, and reduces the need for cleaning or replacing the filter. Downtime is reduced, improving the overall operating efficiency of the pipeline system. A positioning screw hole 506 is provided on the surface of the tee bend 1, and a positioning bolt 503 is installed inside the positioning screw hole 506. The bottom end of the positioning bolt 503 engages with the top surface of the filter assembly 5. A limiting groove 505 is provided on the surface at the intersection of the first filter disc 501 and the second filter disc 502. A limiting block 504 is provided on the bottom surface of the positioning bolt 503, and the limiting block 504 is clearance-fitted with the limiting groove 505. The top surface cross-section of the limiting block 504 is a regular polygon, and the adjacent sides of the limiting block 504... The endpoint of the filter assembly 5 is located at the edge of the positioning bolt 503. The first filter disc 501 and the second filter disc 502 are the same size. The outer edge of the first filter disc 501 abuts against the inner wall of the three-way bend 1. The positioning screw hole 506 provides an installation position for the positioning bolt 503. The positioning bolt 503 is used to fix the position of the filter assembly 5 inside the three-way bend 1 and to realize the rotation adjustment of the filter disc. The positioning bolt 503 passes through the positioning screw hole 506 and engages with the top surface of the filter assembly 5. Rotating the positioning bolt 503 drives the filter assembly 5 to rotate. The limiting block 504 on its bottom surface is clearance-fitted with the limiting groove 505 on the surface where it intersects with the filter disc. This ensures rotational flexibility while preventing excessive displacement of the filter disc. During installation, the positioning bolt 503 is passed through the positioning screw hole 506 and tightened, so that the limiting block 504 is engaged in the limiting groove 505, fixing the filter assembly 5. When it is necessary to switch the filter disc, loosen the positioning bolt 503, rotate it to the appropriate position, and then tighten it again to accurately position the filter assembly 5, which facilitates the switching operation of the filter disc and improves the maintainability and flexibility of the filter assembly 5.

[0030] The flow guide assembly includes a central sphere body 601 and conical spiral blades 602. The conical spiral blades 602 are evenly distributed on the surface of the central sphere body 601. The flow guide assembly 6 engages with the inner wall of the tee bend 1 at the connection point. The end of the conical spiral blade 602 closest to the central sphere body 601 has a smaller diameter. The central sphere body 601 serves as the core support structure of the flow guide assembly 6, providing the mounting base for the conical spiral blades 602 and driving the entire flow guide assembly 6 to rotate under the impact of the fluid. When the fluid enters the tee bend 1 and comes into contact with the flow guide assembly 6, the impact force of the fluid acts on the central sphere body 601, causing it to rotate. The central sphere body 601 begins to rotate under the impact of the liquid, driving the conical spiral blades 602 on its surface to rotate as well, changing the flow state of the fluid, providing stable support for the rotation of the flow guide blades, ensuring that the flow guide assembly 6 can work normally under the action of the fluid, and achieving effective flow guidance.

[0031] The conical helical blade 602 guides the fluid through its shape and rotational motion, causing the fluid to form vortices, preventing fluid accumulation, and accelerating the rapid flow of the fluid. When the central sphere 601 rotates, the conical helical blade 602 rotates as well. Its special conical helical shape causes the fluid to flow along the curved surface of the blade, forming a vortex-like flow pattern. After the fluid enters the T-bend 1, it impacts the guide ball assembly 6. During the rotation, the conical helical blade 602 continuously changes the flow direction and velocity of the fluid, transforming the fluid that might have accumulated or had uneven flow velocity into vortex flow, promoting the rapid transmission of the fluid in the pipe, effectively improving the flow characteristics of the fluid in the T-bend 1, reducing pressure loss and accumulation at the pipe connection, and improving the fluid transmission efficiency of the entire pipeline system.

[0032] A sealing seat 3 is provided inside the tee bend 1 near the mounting thread 2. A sealant 4 is fitted onto the surface of the sealing seat 3. The sealing seat 3 is threaded to the inside of the tee bend 1 near the mounting thread 2, providing a carrier for the sealant 4. Together, they seal the connection of the tee bend 1. The sealing seat 3 is tightly fixed inside the tee bend 1 through the threaded connection. Its surface mates with the sealant 4 to fill the gaps in the connection and prevent fluid leakage.

[0033] The sealant 4 fills the tiny gaps between the sealing seat 3 and other connecting parts, enhancing the sealing effect and ensuring that the fluid can only flow within the specified pipe channel without leaking from the connection. When the sealing seat 3 is installed in place, the sealant 4 is squeezed at the connection, filling the gaps and forming a sealing layer, ensuring the sealing of the T-bend 1 connection, preventing fluid leakage from polluting the surrounding environment or affecting the normal operation of the pipeline system, and improving the reliability and safety of the entire connection. Specific Implementation Example 2:

[0035] Reference Figure 1-6 Based on the content of the above specific embodiments, the following content is further disclosed:

[0036] When the fluid enters the tee bend 1 and flows towards the guide ball assembly 6, the flow guiding process is as follows:

[0037] First, the fluid exerts an impact force on the central sphere body 601. Since the central sphere body 601 is located at the pipe connection point and can rotate freely, it begins to rotate under the action of this impact force. The conical helical blades 602, which are evenly distributed on the surface of the central sphere body 601, rotate accordingly.

[0038] The special shape of the conical helical blade 602 guides the fluid during rotation. Its end near the central spherical body 601 is a small-diameter end; this structure causes the fluid to gradually change direction along the helical surface of the blade upon contact. As the fluid flows from the small-diameter end to the large-diameter end of the blade, it is continuously pushed outwards, forming a helical trajectory and thus creating a vortex flow.

[0039] This vortex flow pattern can break the tendency of fluid to accumulate at pipe junctions due to abrupt changes in flow direction. Because the vortex gives fluid molecules motion components in all directions, it prevents them from simply being compressed and accumulated in one direction, instead allowing them to flow in a more ordered and dispersed manner within the pipe. For example, in the case of confluence, fluids flowing in from different directions rapidly merge and form a stable vortex under the action of the guide ball assembly 6, then flow uniformly towards the outlet; in the case of diversion, the vortex flow pattern allows the fluid to be evenly distributed into each branch pipe.

[0040] Meanwhile, the vortex flow pattern reduces the collision and frictional resistance between fluids and between the fluid and the pipe wall, thereby reducing pressure loss and enabling the fluid to be transported in the pipeline with higher efficiency. This ensures the stable, rapid and efficient transport of fluid in the entire pipeline system and effectively improves the performance of the tee connector in complex fluid transport scenarios. Specific Implementation Example 3:

[0042] Reference Figure 1-6 Based on the content of the above specific embodiments, the following content is further disclosed:

[0043] In actual use, the number of filter discs connected to the surface of filter assembly 5 is set according to actual usage requirements. It can be set to three groups, four groups, etc. Generally, the filter discs are kept to overlap on the central axis. The diameter of the filter holes on the surfaces of adjacent filter plates can be set to be different or the same, which facilitates long-term filtration inside the three-way bend 1 and avoids frequent disassembly.

[0044] In addition to the above-mentioned installation structure, the filter assembly 5 can also be configured to be connected to the three-way bend via shafts at the top and bottom, so that the entire filter assembly 5 can rotate along the installation shaft. This allows the filter assembly to filter impurities from the liquid flowing into the three-way bend 1 while rotating under the impact of the liquid, thus guiding the liquid flow and preventing liquid accumulation.

[0045] In summary:

[0046] 1. A filter assembly 5 is installed inside the three-way bend 1 near the port to filter impurities in the fluid. This changes the traditional fixed single-piece filter structure. The first filter disc 501 and the second filter disc 502 are installed by perpendicularly overlapping each other. Positioning and rotation adjustment are achieved by positioning bolts 503. When there are many impurities on the surface of the first filter disc 501, the filter assembly 5 can be rotated directly by positioning bolts 503 to switch to the second filter disc 502 for filtration. This greatly reduces downtime for maintenance, improves production and operation efficiency, and reduces maintenance costs. Under the same filtration time and fluid flow rate, more impurity particles can be captured, effectively improving filtration efficiency and filtration accuracy. This ensures the purity of the fluid in the subsequent pipeline transmission process, reduces pipeline blockage and equipment wear caused by impurities, and extends the service life of the entire pipeline system and related equipment.

[0047] 2. A flow guide ball assembly 6 is installed at the pipe connection points in three directions inside the tee bend 1. The conical spiral blades 602 evenly distributed on the surface of the central ball body 601 cause the entire flow guide ball assembly 6 to rotate and vibrate rapidly under the impact of the liquid entering. This rotational motion, combined with the special shape of the conical spiral blades 602, can cleverly change the flow pattern of the fluid, guiding the fluid that might otherwise flow in a straight line or disorderly manner to form a vortex. The formation of the vortex flow pattern effectively breaks the accumulation phenomenon that easily occurs at the pipe connection, allowing the fluid to be transmitted more evenly and smoothly in the tee bend 1 and subsequent pipes. This not only reduces the pressure loss of the fluid when flowing in the pipe and improves the dynamic efficiency of fluid transmission, but also ensures that the fluid can stably perform diversion or merging operations through the tee connector under different flow rate and velocity conditions. It avoids pipe vibration, noise and other problems caused by poor fluid flow, and improves the stability and reliability of the entire pipeline system. It is especially suitable for industrial production and chemical fluid transportation fields with high requirements for fluid transmission efficiency and stability.
