Description

Technical Field

[0001] This utility model belongs to the technical field of grooved pipe fittings, and more specifically, it relates to a grooved reducing tee fitting. Background Technology

[0002] In water supply and drainage, fire protection, HVAC, and industrial piping systems, reducing tees are often used to connect pipes of different diameters. Grooved reducing tees are an important type of tee connection. Existing grooved reducing tees mainly consist of a main pipe and branch pipes. The main pipe has the same diameter at both ends, while the branch pipe has a different diameter. They are primarily made of ductile iron (galvanized), stainless steel (304 / 316), and carbon steel, adaptable to different media (water, gas, oil, etc.) and operating conditions (pressure, corrosiveness).

[0003] Existing application number CN202321611129.7 discloses a grooved reducing tee pipe, including a main pipe and a branch pipe. The branch pipe is fixedly connected to the middle of the outer surface of the main pipe, and the branch pipe is perpendicular to the main pipe. A groove is formed on the outer surface of the main pipe near the port, and a ring of protrusions is provided on the outer surface of the main pipe next to the groove. The advantages of this utility model are: by screwing an internal hexagonal head into a screw rod to connect the internal rib and the central rod of the branch pipe, this structure effectively provides internal support to the tee pipe without affecting the normal flow of fluid inside the tee pipe, effectively improving the torsional resistance of the tee pipe, and overcoming the torsional deformation caused by uneven stress around the tee pipe joint. Without increasing the wall thickness and size of the tee pipe, the rigidity and strength of the tee pipe are increased. At the same time, the screw rod can effectively connect the branch pipe and the reinforcing structure inside the main pipe, further improving the overall structure, further improving the rigidity and strength of the tee pipe, making it impact-resistant, deformation-resistant, and structurally strong.

[0004] Based on the above, when water flows from the branch pipe into the main pipe, the existing grooved reducing tee fittings have strong water pressure that directly impacts a specific area of ​​the main pipe's inner wall. The inner wall of the main pipe will be subjected to high water pressure and impact. Under such high-frequency and high-intensity hydraulic impact environment for a long time, the inner wall of the main pipe is very prone to damage such as local wear and fatigue cracks. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a grooved reducing tee fitting. This solves the problem that with existing grooved reducing tee fittings, when water flows from the branch pipe into the main pipe, the strong water pressure directly impacts a specific area of ​​the main pipe's inner wall. The inner wall of the main pipe is subjected to significant water pressure and impact, and under such high-frequency, high-intensity hydraulic impact for a long time, the inner wall of the main pipe is prone to damage such as localized wear and fatigue cracks.

[0006] The purpose and function of this grooved reducing tee pipe fitting are achieved by the following specific technical means:

[0007] A grooved reducing tee fitting includes a main pipe fitting, a groove, baffles, a branch pipe fitting, connecting threads, reinforcing rings, a reinforcing assembly, and a buffer assembly. The groove is formed on the left and right sides of the main pipe fitting. Multiple sets of baffles are arranged in a circumferential array on the left and right sides of the main pipe fitting. The branch pipe fitting is fixedly connected to the middle of the main pipe fitting. The connecting threads are formed inside the branch pipe fitting. Two sets of reinforcing rings are arranged on both sides inside the main pipe fitting. The reinforcing assembly is located inside the main pipe fitting. The buffer assembly is located inside the main pipe fitting.

[0008] Furthermore, the reinforcing assembly includes: reinforcing ribs, wherein multiple sets of reinforcing ribs are provided, and the multiple sets of reinforcing ribs are fixedly installed in the middle position of two sets of reinforcing rib rings, wherein the reinforcing ribs are triangular in structure.

[0009] Furthermore, the reinforcing component also includes: a chamfered surface, wherein two sets of chamfered surfaces are provided, and the two sets of chamfered surfaces are opened inside the two sets of reinforcing rib rings.

[0010] Furthermore, the reinforcing assembly also includes: a limiting ring and alloy bolts. The limiting ring is provided in two sets, and the two sets of limiting rings are respectively provided on the outside of the two sets of reinforcing rib rings. The alloy bolts are provided in multiple sets, and the multiple sets of alloy bolts pass through the inside of the limiting ring and are threadedly connected to the inside of the reinforcing rib ring.

[0011] Furthermore, the reinforcing assembly also includes: limiting plates and fixing rubber rings. The limiting plates are provided in two sets, and the two sets of limiting plates are fixedly installed inside the two sets of limiting rings. The fixing rubber rings are provided in two sets, and each set of fixing rubber rings is located in the middle of a set of limiting rings and a set of reinforcing rings.

[0012] Furthermore, the buffer assembly includes a buffer base, which is fixedly connected inside a set of reinforcing ribs.

[0013] Furthermore, the buffer assembly also includes a buffer cone and an annular groove, wherein the buffer cone is fixedly installed on the upper part of the buffer base; and the annular groove is formed inside the buffer base.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Firstly, this invention features a reinforced assembly. Through a three-dimensional support structure composed of reinforcing ribs and triangular reinforcing rods, it provides distributed support to the inner wall of the main pipe component, evenly dispersing fluid pressure and effectively suppressing deformation or cracking caused by uneven stress. The design of the limiting ring and alloy bolts, through the compression and fixing of the rubber ring, achieves a tight fit between the frame and the inner wall of the main pipe component. The chamfered design optimizes the fluid flow path at the reinforcing ribs, reducing water flow resistance and turbulence, thus improving structural strength while avoiding additional energy loss.

[0016] Secondly, this invention features a buffer component. The conical structure of the buffer cone initially diverts the high-speed water flow entering from the branch pipe, converting the concentrated impact kinetic energy into dispersed fluid potential energy. Its rounded top design reduces direct scouring and wear on the buffer cone, extending the component's service life. The annular groove inside the buffer base achieves secondary buffering through the vortex effect. Water entering the groove forms a rotating flow, and the kinetic energy gradually decreases through fluid friction and collision, significantly reducing the impact force and frequency of the water flow on the inner wall of the main pipe, reducing fatigue damage to the inner wall of the main pipe, and improving the durability of the pipe under high-pressure, high-frequency impact conditions.

[0017] This utility model has the advantages of high structural strength, excellent buffering performance, and reduced deformation. The stiffening components enhance the rigidity of the main pipe, disperse fluid pressure, and reduce the risk of deformation. The buffer components effectively divert and attenuate the impact force of water flow, reducing the harm of water hammer. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 5 As shown:

[0028] This utility model provides a grooved reducing tee fitting, including a main pipe fitting 1, a groove 101, baffles 102, a branch pipe fitting 2, a connecting thread 201, reinforcing rib rings 3, and a reinforcing assembly. The groove 101 is formed on the left and right sides of the main pipe fitting 1; multiple sets of baffles 102 are arranged in a circumferential array on the left and right sides of the main pipe fitting 1; the branch pipe fitting 2 is fixedly connected to the middle of the main pipe fitting 1; the connecting thread 201 is formed inside the branch pipe fitting 2; two sets of reinforcing rib rings 3 are arranged on the two sides inside the main pipe fitting 1; and the reinforcing assembly is arranged inside the main pipe fitting 1.

[0029] The reinforcing component includes: reinforcing ribs 302, multiple sets of reinforcing ribs 302 are provided, and multiple sets of reinforcing ribs 302 are fixedly installed in the middle position of two sets of reinforcing rib rings 3. The reinforcing ribs 302 have a triangular structure.

[0030] The reinforcing component also includes: a chamfered face 301, which is provided in two sets, and the two sets of chamfered face 301 are opened inside the two sets of reinforcing rib rings 3.

[0031] The reinforcing assembly also includes: a limiting ring 303 and alloy bolts 304. Two sets of limiting rings 303 are provided, and the two sets of limiting rings 303 are respectively located on the outside of the two sets of reinforcing rings 3. Multiple sets of alloy bolts 304 are provided, and the multiple sets of alloy bolts 304 pass through the inside of the limiting rings 303 and are connected to the inside of the reinforcing rings 3 by threads.

[0032] The reinforcing component also includes: a limiting piece 3031 and a fixing ring 305. Two sets of limiting pieces 3031 are provided, and the two sets of limiting pieces 3031 are fixedly installed inside the two sets of limiting rings 303. Two sets of fixing rings 305 are provided, and each set of fixing rings 305 is located in the middle of a set of limiting rings 303 and a set of reinforcing rings 3.

[0033] The specific usage and function of this embodiment are as follows:

[0034] The support frame, consisting of reinforcing ribs 3 and rib rods 302, is inserted into the main pipe component 1. By tightening the alloy bolts 304, the limiting ring 303 is moved towards the reinforcing ribs 3. During this process, the fixing rubber ring 305, sandwiched between the limiting ring 303 and the reinforcing ribs 3, undergoes elastic deformation under compression. Its outer edge extends outward from the limiting ring 303, tightly adhering to and compressing the inner wall of the main pipe component 1, forming a stable compression-type limiting structure, thus completing the installation and fixation of the frame within the main pipe component 1. The limiting piece 3031 constrains the deformation direction of the fixing rubber ring 305, ensuring its full outward extension. The fixing rubber ring 305 is made of highly elastic and corrosion-resistant materials, such as EPDM rubber and fluororubber, which can resist the erosion of various fluid media and withstand long-term water flow impact, possessing excellent deformation resistance and aging resistance, effectively ensuring the durability and reliability of the frame installation.

[0035] The three-dimensional support structure composed of reinforcing rings 3 and reinforcing rods 302 can evenly distribute and bear the fluid pressure from inside the pipe, significantly improving the structural rigidity and strength of the main pipe component 1. When water flows from branch pipe component 2 into the main pipe component 1, the high-speed water flow impacts the inner wall of the main pipe component 1 and forms a dispersed flow. At this time, the triangular cross-section of the reinforcing rod 302 structure generates a turbulence effect on the dispersed water flow, effectively weakening the impact force of the water flow and reducing the scouring and wear of the water flow on the pipe wall. Meanwhile, the chamfered edge 301 on the inner side of the reinforcing ring 3 guides the water flow more smoothly to both ends of the main pipe component 1, reducing water flow resistance, reducing energy loss, and thus extending the service life of the pipe component and ensuring the stable operation of the pipeline system.

[0036] In this embodiment, the material of the fixing ring 305 is a mature existing technology, and will not be described in detail here.

[0037] Example 2:

[0038] Based on Example 1, such as Figures 1 to 5 As shown, it also includes a buffer component, which is located inside the main component 1.

[0039] The buffer assembly includes a buffer base 401, which is fixedly connected inside a set of reinforcing ribs 302.

[0040] The buffer assembly also includes a buffer cone 4 and an annular groove 4011. The buffer cone 4 is fixedly installed on the upper part of the buffer base 401; the annular groove 4011 is formed inside the buffer base 401.

[0041] The specific usage and function of this embodiment are as follows:

[0042] The buffer base 401 is installed inside the reinforcing rib 302 opposite to the branch pipe fitting 2, forming a stable buffer fulcrum. When high-speed water flows from the branch pipe fitting 2 into the main pipe fitting 1, the buffer cone 4, with its conical structure, evenly guides the concentrated impact of the water flow to all sides, achieving initial flow diversion and buffering. The rounded transition design at the top of the buffer cone 4 effectively disperses the impact force of the water flow, reduces the cutting effect of the water flow on the cone surface, and significantly improves its wear resistance and service life.

[0043] After being diverted by the buffer cone 4, the water flow then enters the annular groove 4011 inside the buffer base 401. The annular groove 4011, through its arc-shaped flow channel design, forces the water flow to generate a vortex effect, converting the kinetic energy of the water flow into heat and potential energy, thus achieving secondary buffering. During this process, the annular groove 4011 doubly attenuates the speed and impact force of the water flow, further reducing the direct impact of the water flow on the inner wall of the main pipe component 1.
