Description

Technical Field

[0001] This utility model relates to the field of tee fittings, and in particular to an externally extended equipotential anti-permeability internal pressure tee. Background Technology

[0002] A tee fitting is a pipe fitting with three interconnected joints. It is a common pipe connection element in liquid pipelines and is often a key component where stress is concentrated. The main function of a tee fitting is to change the direction of fluid flow, allowing fluid to flow into pipes in different directions. Tee fittings are a type of pipe connector, available in equal diameter and reducing diameter versions. They are used where pipelines branch, and due to their ease of use, they are widely used in chemical, civil construction, machinery manufacturing, and shipbuilding industries. Commercially available tee fittings are generally made of one-piece molded plastic, offering good overall structural strength and robustness.

[0003] The existing tee fittings have the same length for all three ports. However, due to the varying connection spaces in different application environments, the distribution of two tee fittings over a relatively short distance, or the need to slightly adjust the spacing of the pipe connections while ensuring sealing performance, requires cutting long pipes for connection, resulting in poor ease of use. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model provides an externally extended equipotential anti-permeability internal pressure tee, which mainly solves the problem of poor ease of use of existing tee fittings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An extended equipotential bonding tee with internal pressure protection includes a tee fitting made of plastic. The tee fitting includes a main pipe and a branch pipe integrally connected to the main pipe. The main pipe has a first interface, a second interface, and a first flow channel connecting the first interface and the second interface. The branch pipe has a third interface and a second flow channel connecting the third interface and the first flow channel. The central axis of the first flow channel is perpendicular to the central axis of the second flow channel. The point where the central axes of the first flow channel and the second flow channel intersect is defined as the perpendicular foot point. The ratio of the distance between the first interface and the perpendicular foot point to the distance between the second interface and the perpendicular foot point is 1:2 to 6. The connection between the first flow channel and the second flow channel is provided with an arc transition structure. The radius of the arc transition structure is 0.5 to 0.9 times the diameter of the first flow channel. The third interface is provided with an equipotential bonding part made of metal material. The equipotential bonding part is integrally injection molded with the tee fitting. The inner surface of the equipotential bonding part is provided with internal threads.

[0007] Furthermore, a through groove is provided on one side of the branch pipe at the third interface, through which the outer side of the equipotential bonding part contacts the outside. A protrusion is provided on the outer side of the equipotential bonding part at the through groove. Sliding grooves are provided on the opposing sides of the through groove. A wire mounting seat is detachably provided at the through groove. The periphery of the wire mounting seat is provided with elastic support feet that cooperate with the sliding grooves. The wire mounting seat is provided with a wire mounting component and a metal plate that have a conductive function. When the wire mounting seat is locked in the through groove, the free end of the metal plate abuts against the protrusion of the equipotential bonding part.

[0008] Furthermore, the mounting assembly includes a metal base fixed on the wire mounting base, the metal base having a threaded hole, the inner end of the threaded hole having a tapered connecting hole, a connecting rod being threadedly connected to the threaded hole, a through hole being provided at the central axis of the connecting rod, a handle being provided at one end of the connecting rod, and at least two clamping claws being spaced apart at the other end of the connecting rod and around the through hole, and the metal plate being fixed to the inner end of the metal base.

[0009] Furthermore, the outer surface of the tee fitting is provided with an annular reinforcing rib located between the perpendicular foot point and the second interface, and the thickness of the annular reinforcing rib is 1.2 to 1.5 times the wall thickness of the main pipe.

[0010] Furthermore, the outer surface of the equipotential bonding portion is provided with anti-slip protrusions.

[0011] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: This extended equipotential anti-permeability internal pressure tee, through an asymmetrical interface length design of 1:2 to 6, adapts to different installation spacing requirements, reduces pipe cutting procedures, and improves installation convenience. Furthermore, the metal equipotential connection part is integrally injection molded with the plastic pipe fitting, possessing both conductivity and structural sealing performance, avoiding the leakage risk of traditional split connections. At the same time, the arc transition structure of 0.5 to 0.9 times the flow channel diameter can reduce fluid resistance and reduce turbulence and pressure loss. Attached Figure Description

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] The embodiment of this utility model is as follows:

[0018] refer to Figures 1 to 4 As shown, an extended equipotential anti-permeability internal pressure tee includes a tee fitting made of plastic. The tee fitting includes a main pipe 1 and a branch pipe 2 integrally connected to the main pipe 1. The main pipe 1 has a first interface 11, a second interface 12, and a first flow channel 13 connecting the first interface 11 and the second interface 12. The branch pipe 2 has a third interface 21 and a second flow channel 22 connecting the third interface 21 and the first flow channel 13. The central axis a of the first flow channel 13 is perpendicular to the central axis b of the second flow channel 22. The point where the central axis a of the first flow channel 13 intersects the central axis b of the second flow channel 22 is defined as the perpendicular point c. The ratio of the distance between the first interface 11 and the perpendicular point c to the distance between the second interface 12 and the perpendicular point c is 1:2 to 6, preferably 1:4. An arc transition structure 3 is provided at the connection between the first flow channel 13 and the second flow channel 22. The radius of the arc transition structure 3 is 0.5 to 0.9 times the diameter of the first flow channel 13, preferably 0.7 times. The third interface 21 is provided with an equipotential bonding part 4 made of metal material. The equipotential bonding part 4 is integrally injection molded with the tee fitting. The inner surface of the equipotential bonding part 4 is provided with an internal thread 5, and the outer surface of the equipotential bonding part 4 is provided with an anti-slip ridge 6.

[0019] This extended equipotential anti-seepage internal pressure tee features an asymmetrical interface length design of 1:2 to 6 to adapt to different installation spacing requirements, reduce pipe cutting procedures, and improve installation convenience. Furthermore, the metal equipotential connection part 4 is integrally injection molded with the plastic pipe fitting, combining conductivity and structural sealing to avoid the leakage risk of traditional split connections. At the same time, the arc transition structure 3 with a flow channel diameter of 0.5 to 0.9 times can reduce fluid resistance, turbulence, and pressure loss.

[0020] Furthermore, a through groove 7 is provided on one side of the branch pipe 2 at the third interface 21, allowing the outer side of the equipotential bonding part 4 to contact the outside. A protrusion 8 is provided on the outer side of the equipotential bonding part 4 at the through groove 7. Sliding grooves 9 are provided on the opposing sides of the through groove 7. A wire mounting seat 10 is detachably provided at the through groove 7. The periphery of the wire mounting seat 10 is provided with elastic support feet 31 that cooperate with the sliding grooves 9. The wire mounting seat 10 is provided with a conductive wire mounting assembly and a metal plate 32. When the wire mounting seat 10 is engaged in the through groove 7, the free end of the metal plate 32 abuts against the protrusion 8 of the equipotential bonding part 4. The detachable wire mounting seat 10, through the elastic engagement structure of the sliding grooves 9, enables rapid installation / replacement of the equipotential wire, improving maintenance convenience. The elastic contact design between the metal plate 32 and the convex strip 8 ensures conductive stability. The mounting assembly includes a metal base 33 fixed on the wire mounting base 10. The metal base 33 has a threaded hole 34, and the inner end of the threaded hole 34 has a tapered connecting hole 35. A connecting rod 36 is threadedly connected to the threaded hole 34. A through hole 37 is provided at the central axis of the connecting rod 36. One end of the connecting rod 36 has a handle 38. At least two clamps 39 are distributed at intervals around the other end of the connecting rod 36 and the through hole 37. The metal plate 32 is fixed to the inner end of the metal base 33. The tapered connecting hole 35 and the multi-clamp structure form a double-stage locking, which improves the wire fixing firmness and provides excellent vibration resistance. The threaded metal base 33 provides a standardized interface, which is compatible with the installation of wires of different specifications.

[0021] Furthermore, an annular reinforcing rib 40 is provided on the outer surface of the tee fitting between the perpendicular point c and the second interface 12. The thickness of the annular reinforcing rib 40 is 1.2 to 1.5 times the wall thickness of the main pipe 1, preferably 1.3 times. The annular reinforcing rib 40 with a wall thickness of 1.2 to 1.5 times improves the pressure bearing capacity of the second interface 12, making it particularly suitable for high-pressure pipeline systems.
