Description

Technical Field

[0001] This utility model relates to the field of pipeline structure technology, and in particular to an auxiliary water supply pipeline structure for boilers. Background Technology

[0002] As is well known, a boiler is a device used to produce steam or hot water, commonly used in industrial, commercial, and residential heating systems. It heats water by burning fuels (such as natural gas, oil, coal, or biomass) to produce steam or hot water, which can then be used to drive turbines, provide heating or cooling, or perform other industrial processes. Boilers come in various designs and structures, including fire-tube boilers, water-tube boilers, steam boilers, and hot water boilers. Since the primary function of a boiler is energy conversion—heating water into steam through fuel combustion—it does not have its own independent water supply mechanism and typically uses auxiliary water supply pipes to introduce water from an external water source into the boiler.

[0003] However, traditional boiler auxiliary water supply pipe structures often contain solid impurities such as mud, rust, and scale particles from natural water sources or water that has not been adequately treated. These impurities accumulate on the inner walls of the pipes, in bends, and at valves as the water flows into the boiler's auxiliary water supply pipes. Over time, the accumulated impurities reduce the effective inner diameter of the pipes, hindering the normal flow of water and reducing water supply efficiency. Therefore, technical improvements are urgently needed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary water supply pipe structure for boilers. When in use, the mounting frame is easily placed in the storage slot via a handle. The filter screen is made of high-strength stainless steel, capable of withstanding long-term impact and pressure from water flow, preventing breakage or deformation during use and ensuring stable filtration. It effectively intercepts solid impurities such as silt, rust, and scale particles in the water. The detachable design facilitates regular cleaning and installation of the filter screen.

[0007] Compared with existing auxiliary water supply pipe structures for boilers, this auxiliary water supply pipe structure improves the sealing performance of the installation point through the sealing gasket ring, effectively preventing water leakage from the pipe connection.
