Description

Technical Field

[0001] This utility model relates to the field of pipe fittings technology, and in particular to a clog-resistant and easy-to-clean reducing tee fitting. Background Technology

[0002] A tee fitting is a connector used in piping systems. It is shaped like the letter "T" and has three openings, which can split the fluid in one pipe into two pipes in different directions, or combine the fluid in two different pipes into one pipe.

[0003] Tee fittings have a wide range of applications. In building water supply and drainage systems, tees can distribute water flow from the main pipeline to branch pipes in various bathrooms and kitchens. In heating systems, they can distribute hot water from the main heating pipeline to radiator branch pipes in various rooms, ensuring uniform heating. In industrial production, tees are also commonly used in pipelines transporting chemical raw materials and gaseous fluids to change flow direction, achieve diversion and merging operations, and meet the needs of complex processes. However, some tees have low adaptability in special transportation operations, so a clog-resistant and easy-to-clean reducing tee fitting is needed.

[0004] The existing anti-clogging and easy-to-clean reducing tee fitting has the following shortcomings:

[0005] Existing reducing tee fittings are all one-piece, which means that in actual use, the tee fittings themselves do not have the ability to clean, causing blockages to flow into the pipe. This makes the reducing tee fittings prone to blockage, and it is difficult to quickly determine the location of the blockage. In addition, because the tee fittings have three channels, the compatibility rate is too low, which delays the construction time and reduces the construction efficiency.

[0006] Therefore, we propose a clog-resistant and easy-to-clean reducing tee fitting to solve the problems mentioned above. Summary of the Invention

[0007] Multiple first mounting heads connect the first and second pipe fittings via threads. Their inner diameter is the same as the latter two, which reduces the contact area between the inner wall of the pipe fitting and the liquid inside the pipe. Removing the first mounting heads allows for segmented cleaning, avoiding cleaning dead spots. Furthermore, the consistent diameter prevents the risk of poor liquid flow and blockage caused by pits and unevenness. This improves the overall practicality and versatility of the pipe fitting, avoids the construction time delays caused by the low matching ratio of conventional pipe fittings, and improves construction efficiency to solve the problems mentioned in the background technology.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a clog-proof and easy-to-clean reducing tee fitting, comprising a first fitting, a threaded ring on the inner side of the first fitting, a first mounting head on the inner side of the first fitting, a leak-proof ring rotatably connected to the inner side of the first mounting head, and a second mounting head fixedly connected to the inner side of the leak-proof ring.

[0009] Preferably, the device includes mounting rods slidably connected to the inner side of the first pipe fitting. Handles are fixedly connected to the outer sides of both mounting rods. Telescopic rods are slidably connected to the inner sides of the two mounting rods. Limiting blocks are fixedly connected to the outer sides of the telescopic rods. Springs are provided on the outer sides of the limiting blocks. The upper and lower ends of the springs are fixedly connected to the two mounting rods. Filter screens are slidably connected to the outer sides of the mounting rods. A cleaning mechanism is provided inside the first pipe fitting.

[0010] Preferably, the inner side of the mounting rod has a cylindrical channel slightly larger than the telescopic rod, through which the mounting rod is slidably connected to the telescopic rod, and a limiting ring is provided in the channel to prevent the telescopic rod from dislodging.

[0011] Preferably, a reinforcing frame is fixed to the outer side of the filter screen, and multiple mounting blocks are fixed on the reinforcing frame. The inner side of each of the multiple mounting blocks is provided with a slide track that is slightly larger than the size of the mounting rod.

[0012] Preferably, a spherical sleeve is provided on the inner side of the other end of the first pipe fitting, a spherical joint is rotatably connected to the inner side of the spherical sleeve, and a second pipe fitting is fixedly connected to the outer side of the spherical joint.

[0013] Preferably, the inner side of the second pipe fitting is provided with a threaded ring, which is threadedly connected to another first mounting head, and the inner side of the first mounting head is rotatably connected to another leak-proof ring, which is fixedly connected to another second mounting head.

[0014] Preferably, a third leak-proof ring is rotatably connected to the inner side of the first mounting head, a third second mounting head is fixedly connected to the outer side of the leak-proof ring, and a sealing ring is fixedly connected to the bottom of the second mounting head.

[0015] Preferably, the outer side of the first pipe fitting is provided with a plurality of reinforcing grooves, and a reinforcing ring is fixedly connected to the inner side of the reinforcing groove.

[0016] Preferably, a waterproof cover is fixedly connected to the outside of the first pipe fitting, and the outside of the waterproof cover has multiple ventilation holes.

[0017] Preferably, the inner wall of the first pipe fitting has a plurality of mounting holes that are slightly larger than the mounting rod, and the inner diameter of the spherical sleeve is slightly larger than the outer diameter of the spherical joint.

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

[0019] 1. In this utility model, the anti-clogging and easy-to-clean reducing tee achieves its anti-clogging and easy-to-clean purpose by using a multi-segment combination. Firstly, multiple first mounting heads are connected to the first and second pipe fittings via threads, and the inner diameter of the first mounting heads is consistent with the inner diameter of the first and second pipe fittings. This design reduces the contact area between the inner walls of the first and second pipe fittings and the liquid inside the pipe. When the first mounting heads are removed, segmented cleaning can be performed, avoiding cleaning dead spots. Furthermore, the consistent diameter prevents pits and unevenness from hindering liquid flow and causing blockages. The risk is mitigated because the inner side of the first mounting head is rotatably connected to the second mounting head via a leak-proof ring. Since the second mounting head is smaller than the first, it can be connected to pipes of various sizes. Furthermore, by dividing the entire pipe fitting into two sections and rotatably connecting the second pipe fitting with a fixed spherical connector to the first pipe fitting with a spherical sleeve, this design allows the entire pipe fitting to rotate within a small range. In summary, this improves the overall practicality and versatility of the pipe fitting, avoids construction delays caused by low matching ratios in conventional pipe fittings, and increases construction efficiency.

[0020] 2. In this utility model, when the pipe fitting needs cleaning, the filter screen inside the pipe fitting can be removed, facilitating unified cleaning of the pipe fitting's interior and targeted cleaning of the filter screen. Because the channels on the inner walls of the first and second pipe fittings are slidably connected to the mounting rod, and the mounting rod also has channels within them, through which a telescopic rod slides, with the outer side of the telescopic rod sliding in contact with the filter screen. The mounting rods are fixed together by a spring, which is sleeved on the telescopic rod. A handle is fixed to the outer side of the mounting rod. When cleaning the filter screen, two fingers are placed on the two handles and squeezed towards the center. The handles drive the mounting rod to slide towards the center along the telescopic rod, causing the spring to contract under force. Because of the limit block on the outside of the telescopic rod, excessive force by the operator can prevent the mounting rod from detaching from the filter screen. This ensures stable operation of the filter screen and facilitates easy removal and cleaning, further increasing the ease of cleaning the pipe fitting. Furthermore, because the filter screen inside the tee fitting can prevent clumped liquid from entering the pipe, the location of the blockage can be quickly determined, reducing maintenance time.

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] Example 1, as shown in the attached document Figure 1 , Figure 2 and Figure 3 As shown, a clog-resistant and easy-to-clean reducing tee fitting includes a first fitting 1, a threaded ring 4 on the inner side of the first fitting 1, a first mounting head 5 on the inner side of the first fitting 1, a leak-proof ring 6 rotatably connected to the inner side of the first mounting head 5, a second mounting head 7 fixedly connected to the inner side of the leak-proof ring 6, and a cleaning mechanism 2 inside the first fitting 1.

[0031] The overall effect achieved by embodiment 1 is as follows: the first mounting head 5 is threadedly connected to the first pipe fitting 1 and the second pipe fitting 3. The inner diameter of the first mounting head 5 is designed to be completely consistent with the inner diameter of the first pipe fitting 1 and the second pipe fitting 3, effectively reducing the contact area between the inner wall of the first pipe fitting 1 and the second pipe fitting 3 and the liquid inside the pipe, avoiding the occurrence of cleaning dead corners. The inner side of the first mounting head 5 is rotatably connected to the second mounting head 7 through the anti-leak ring 6. The pipe fitting is divided into two sections: the first pipe fitting 1 and the second pipe fitting 3. A ball joint 8 is fixed on the second pipe fitting 3, while a ball sleeve 9 is provided on the first pipe fitting 1. The ball joint 8 and the ball sleeve 9 cooperate with each other, so that the two can be rotatably connected.

[0032] Example 2, as Figure 2 and Figure 4 As shown, the device includes an installation rod 201, which is slidably connected to the inner side of the first pipe fitting 1. A handle 202 is fixedly connected to the outer side of each of the two installation rods 201. A telescopic rod 203 is slidably connected to the inner side of the two installation rods 201. A limit block 204 is fixedly connected to the outer side of the telescopic rod 203. A spring 205 is provided on the outer side of the limit block 204. The upper and lower ends of the spring 205 are fixedly connected to the two installation rods 201. A filter screen 206 is slidably connected to the outer side of the installation rods 201.

[0033] The effect achieved by the entire embodiment 2 is as follows: the inner side of the first pipe 1 and the second pipe 3 is slidably connected to the installation rod 201 through the hole opened in the inner wall, and the spring 205 is sleeved on the telescopic rod 203. When two fingers are placed on the two handles 202, the two handles 202 can be squeezed in the middle. The handles 202 drive the installation rod 201 to slide in the middle along the telescopic rod 203. At this time, the spring 205 is compressed by force, and the limiting block 204 fixed outside the telescopic rod 203 can prevent the operator from squeezing the installation rod 201 with too much force and causing it to detach from the filter screen 206.

[0034] Example 3, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the inner side of the mounting rod 201 has a cylindrical channel slightly larger than that of the telescopic rod 203. The mounting rod 201 is slidably connected to the telescopic rod 203 through this channel, and a limiting ring is provided in the channel to prevent the telescopic rod 203 from dislodging. The outer side of the filter screen 206 is fixed with a reinforcing frame, and multiple mounting blocks are fixed on the reinforcing frame. The inner side of each mounting block has a slide rail slightly larger than that of the mounting rod 201.

[0035] The effect achieved by the entire embodiment 3 is as follows: the reinforcing frame supports the entire filter screen 206 and connects the filter screen 206 to the pipe, and the mounting block realizes the flexible connection between the filter screen 206 and the pipe, allowing the filter screen 206 to be freely installed and removed.

[0036] Example 4, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a spherical sleeve 9 is provided on the inner side of the other end of the first pipe fitting 1. A spherical connector 8 is rotatably connected to the inner side of the spherical sleeve 9. A second pipe fitting 3 is fixedly connected to the outer side of the spherical connector 8. A threaded ring 4 is provided on the inner side of the second pipe fitting 3. Another first mounting head 5 is threadedly connected to the threaded ring 4. Another leak-proof ring 6 is rotatably connected to the inner side of the first mounting head 5. The leak-proof ring 6 is fixedly connected to another second mounting head 7. A third leak-proof ring 6 is rotatably connected to the inner side of the first mounting head 5. A third second mounting head 7 is fixedly connected to the side, and a sealing ring 14 is fixedly connected to the bottom of the second mounting head 7. Multiple reinforcing grooves 10 are opened on the outer side of the first pipe fitting 1, and a reinforcing ring 11 is fixedly connected to the inner side of the reinforcing groove 10. A waterproof cover 12 is fixedly connected to the outer side of the first pipe fitting 1, and multiple ventilation holes 13 are opened on the outer side of the waterproof cover 12. Multiple mounting holes slightly larger than the mounting rod 201 are opened on the inner wall of the first pipe fitting 1. The inner diameter of the spherical sleeve 9 is slightly larger than the outer diameter of the spherical joint 8.

[0037] The overall effect of embodiment 4 is as follows: the rotatable connection between the ball joint 8 and the ball sleeve 9 allows them to change their angle, increasing the versatility and practicality of the pipe body; the leak-proof ring 6 does not leak water when the first mounting head 5 and the second mounting head 7 can be connected, and the two can rotate when necessary; the reinforcing groove 10 opened on the outside of the first pipe fitting 1 can fix the reinforcing ring 11, increasing the strength of the pipe fitting and preventing pipe bursting; the waterproof cover 12 can reduce rusting at the pipe fitting joint, and the ventilation holes 13 opened on the waterproof cover 12 can prevent water vapor from accumulating inside the waterproof cover 12 and breeding microorganisms.

[0038] The working principle of the entire device is as follows: Multiple first mounting heads 5 are connected to the first pipe fitting 1 and the second pipe fitting 3 via threaded connections. During this process, the inner diameter of the first mounting head 5 is intentionally designed to be exactly the same as the inner diameter of the first pipe fitting 1 and the second pipe fitting 3. This effectively reduces the contact area between the inner walls of the first and second pipe fittings and the liquid inside the pipe. When cleaning the inside of the pipe fittings is required, the first mounting heads 5 are removed, allowing for segmented cleaning. This effectively avoids the formation of cleaning dead zones. Furthermore, the identical diameter design prevents blockages caused by pits or unevenness in the pipe walls, which could obstruct the flow of liquid inside the pipe. The inner side of the fitting is rotatably connected to the second mounting head 7 via a leak-proof ring 6. Since the size of the second mounting head 7 is smaller than that of the first mounting head 5, it is capable of connecting pipes of various sizes, thus broadening the adaptability range of the fitting. The entire fitting is divided into two sections: the first fitting 1 and the second fitting 3. The second fitting 3 is fixed with a ball joint 8, while the first fitting 1 is provided with a ball sleeve 9. The ball joint 8 and the ball sleeve 9 cooperate with each other, enabling them to be rotatably connected. With this design, the fitting as a whole has the function of allowing the pipe to rotate within a small range of angles, which provides convenience for the pipeline system in complex installation environments or to cope with small displacement changes in actual operation.

[0039] An installation rod 201 is slidably connected to the inner side of the first pipe fitting 1 and the second pipe fitting 3 through a channel opened in the inner wall. A telescopic rod 203 is slidably connected to the installation rod 201 through a channel opened in the installation rod 201. The outer side of the telescopic rod 203 slides with the filter screen 206. The installation rod 201 is fixed to each other by a spring 205, and the spring 205 is sleeved on the outside of the telescopic rod 203. A handle 202 is fixed on the outer side of the installation rod 201. First, place two fingers on the two handles 202, and then squeeze the two handles 202 towards the middle. The handles 202 drive the installation rod 201 to slide towards the middle along the telescopic rod 203. At this time, the spring 205 is compressed by force, and the limiting block 204 fixed on the outside of the telescopic rod 203 can prevent the operator from squeezing the installation rod 201 with excessive force and causing it to detach from the filter screen 206. Thus, while ensuring that the filter screen 206 can work stably, the filter screen 206 can be easily removed during cleaning.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
