[0001] This utility model relates to the field of pipeline diversion technology, specifically a multi-channel pipeline diversion structure. Background Technology

[0002] In HVAC engineering, the piping system is the core component for achieving indoor temperature regulation. As a key link in the HVAC piping system, the multi-channel pipe distribution structure is mainly used to distribute the fluid in the main pipeline to different branch pipelines according to the needs, so as to meet the heating or cooling needs of different areas. It is widely used in HVAC systems of various places such as residential buildings, commercial buildings, and industrial plants.

[0003] Currently, the design of filter components in existing multi-channel pipe diversion structures in the HVAC field has significant shortcomings, resulting in poor filter replacement convenience. In existing structures, most filter components are fixedly connected to the main pipe body, such as by welding or multiple sets of bolts. When filter replacement is required, maintenance personnel need to disassemble a large number of connecting bolts, and in some cases, the pipe may need to be cut or disassembled. The operation process is complicated, which not only consumes a lot of manpower and time, but may also damage the sealing and structural integrity of the pipe, further increasing the difficulty and cost of filter replacement, and seriously affecting the maintenance efficiency and normal operation of HVAC piping systems. To address this, we propose a multi-channel pipe diversion structure. Utility Model Content

[0022] Working principle: Install the multi-channel pipe diversion structure correctly according to the diagram. This multi-channel pipe diversion structure is used in the HVAC field. During operation, the fluid first enters the main pipe 1. By operating the control valve 2 at the output end of the main pipe 1, the flow and cut-off control of the three equally distributed diversion pipes 6 can be realized, thereby completing the diversion operation of the main pipe 1. The branch pipe assembly and the control valve 2 are connected by flange 1 7 and flange 2 10. After the fluid enters the branch pipe 5 through the control valve 2, it will flow through the filter structure composed of filter cylinder frame 3 and filter element 4. The filter plate 20 on the inner wall of the filter element 4 filters the fluid. The filter cylinder frame 3 slides with the sliding groove 15 on the inner wall of the branch pipe 5 through the slider 17, and remains stable under the compression of the spring 13 in the cylindrical cavity 12. At the same time, the rubber sealing ring 16 at both ends of the filter cylinder frame 3 cooperates with the sealing groove 23 and sealing groove 11 respectively to ensure the overall pipeline sealing.

[0023] When filter element 4 needs to be replaced or cleaned, there is no need to shut down the entire pipeline system. Simply close the control valve 2 of the corresponding branch line to cut off the fluid flow in that branch line and prevent fluid leakage. Then disconnect the flange connection between the control valve 2 and the branch pipe 5. At this time, the spring 13, which was originally in a compressed state, will release its rebound force and automatically pop the filter cartridge 3 outward along the slide groove 15. There is no need for maintenance personnel to manually disassemble or pry the filter cartridge 3, which greatly reduces the operation intensity. After the filter cartridge 3 pops out, the filter element 4 can be easily pulled out from the installation port 18 of the filter cartridge 3 with the help of the anti-slip wall 22 on the outside of the filter element 4. Clean the filter plate 20 or replace it with a new filter element 4. After replacement, simply put the filter element 4 back into the filter cartridge frame 3 through the installation port 18, and make the rubber sealing ring 21 on the side of the filter element 4 cooperate with the sealing groove 19 to ensure a seal. Then, push the slider 17 of the filter cartridge frame 3 into the slide groove 15 of the branch pipe 5. During the process, the slider 17 squeezes the mating ring 14, which compresses the spring 13 again. Finally, align the slide groove 15 with the mating block 9 of the flange 7 and snap it in. Complete the flange connection with the adapter bolts, and the normal operation of the branch line can be quickly restored. The entire replacement process does not require complicated tools and is simple and efficient.
