Description

Technical Field

[0001] This utility model relates to the field of pipe fittings technology, and in particular to a three-dimensional multifunctional pipe fitting. Background Technology

[0002] With the continuous development of modern industry and construction, pipeline systems are being used more and more widely and complexly in various fields. Whether it's physical transportation and water supply and drainage in industrial production, or heating, ventilation, air conditioning, and fire protection systems in buildings, efficient and reliable pipeline connection methods are essential. In these pipeline systems, pipelines with different functions and directions often need to be connected, aggregated, or branched to ensure the normal operation of the entire system.

[0003] Over the past few decades, pipe connection technology has continuously evolved, from early simple socket and threaded connections to today's diverse connection methods such as welding, flange connections, and thermofusion connections. Simultaneously, the variety of pipe fittings has also increased, with various standard sizes of elbows, tees, and crosses appearing to meet different pipe connection needs. However, with the ever-increasing demands on the performance of piping systems, especially in terms of space utilization, ease of maintenance, and system stability, existing pipe connection technologies and fittings are gradually showing their limitations.

[0004] In water treatment systems, it is often necessary to collect and treat water from different sources, or to distribute treated water to different points of use. For example, in wastewater treatment plants, sewage pipes from various workshops and areas need to be connected to the main treatment pipeline, which involves a large number of pipe connections and diversion operations. In HVAC systems, to achieve temperature regulation in different areas of a building, heating or cooling pipes need to be connected to radiators or air conditioning terminal equipment in each room, which also presents complex pipe connection problems.

[0005] Existing pipe connections occupy a lot of space. When multiple standard pipe fittings such as tees and crosses are combined and connected, each fitting has its own specific size and shape, and a certain amount of operating space needs to be reserved during the connection process. This results in the entire connection structure occupying a large space. In some space-constrained locations, the original building structure may not provide enough space to accommodate such complex pipe connection structures, thus limiting the modification and upgrading of the piping system.

[0006] Furthermore, the existing pipeline layout is chaotic. With multiple pipe fittings combined, the pipeline's direction and arrangement often become intricate. Pipelines crossing and overlapping in different directions result in a lack of regularity and order in the overall pipeline system layout. This not only creates difficulties during construction, increasing the complexity and time cost, but also makes it difficult for maintenance personnel to quickly and accurately identify and trace the direction and connections of each pipeline during later maintenance and repair work, hindering the rapid location of faults and significantly reducing maintenance efficiency.

[0007] Furthermore, the risk of leakage is high because the combination of multiple pipe fittings means there are numerous connection points. Each connection point requires sealing to prevent fluid leakage from the pipeline. However, in actual use, due to factors such as temperature changes, pressure fluctuations, and pipeline vibration, the seals at the connection points are prone to aging and damage, leading to leakage. Once a leak occurs at a connection point, it not only wastes resources but may also damage surrounding equipment and building structures, seriously affecting the normal operation and stability of the system.

[0008] Therefore, in order to address the above problems, this utility model urgently needs to provide a three-dimensional multifunctional pipe fitting. Utility Model Content
