Description

Technical Field

[0001] This utility model belongs to the field of pipeline diversion technology, and in particular relates to a fire pipeline diverter with a built-in filter. Background Technology

[0002] In modern fire protection systems, fire hydrant distributors are crucial components. In high-rise building fire protection systems, vertically distributed piping systems are prone to water pressure gradient differences. Fire hydrant distributors have dynamic adjustment capabilities and, through pressure balancing design, convert the high-pressure water flow from the main pipeline into a stable water pressure suitable for fire hydrants and sprinkler systems on each floor. Their function is to rationally distribute the water flow in the fire water supply pipeline to different areas or fire equipment, ensuring that all parts can obtain sufficient fire water in a timely manner when a fire occurs.

[0003] Current fire-fighting pipe diverters typically lack filtration capabilities. This leads to impurities such as mud, rust, and welding slag in the fire-fighting water entering the diverter and accumulating in narrow areas such as elbows, valve interfaces, and branch pipe inlets. In high-rise buildings, the diverter can even become clogged, exacerbating pressure imbalances in vertical pipes. This can cause pipes in lower zones to rupture due to excessive pressure, while higher zones may be unable to extinguish fires due to insufficient water flow. Therefore, we propose a fire-fighting pipe diverter with a built-in filter. Utility Model Content

[0004] The purpose of this invention is to provide a fire-fighting pipeline diverter with a built-in filter. By setting up a filtration assembly, specifically, water flows through a water pipe and first enters filter element two, where large particles of impurities are trapped. Then, it flows into filter element one for secondary filtration, achieving graded interception of impurities. Finally, two valves are opened to discharge the filtered fire-fighting water, preventing critical equipment such as sprinkler heads and fire pumps from malfunctioning due to impurities clogging the system. This ensures a rapid response of the fire-fighting system in the event of a fire. It also solves the problem that existing fire-fighting pipeline diverters typically lack filtration capabilities, leading to the accumulation of impurities such as mud, rust, and welding slag in the fire-fighting water within narrow areas such as bends, valve interfaces, and branch pipe inlets.

[0036] Sealing mechanism 3 is installed on the right side of housing 1 and serves a sealing function.

[0037] The filtration mechanism 2 includes a filter assembly 21, which is installed inside the housing 1 and is used to filter the liquid inside the housing 1.

[0038] Disassembly assembly 22 is installed on top of filter assembly 21 and is used for installation and disassembly.

[0039] The sealing mechanism 3 includes a connecting assembly 31, which is mounted on the right side of the housing 1 and is used to connect the various components.

[0040] The sealing component 32 is installed on the right side of the connecting component 31 and serves a sealing function.

[0041] The filter assembly 21 includes a filter element 211 disposed inside the housing 1. A support ring 212 is installed on the top of the filter element 211. A filter element 213 is disposed inside the filter element 211. A V-shaped sealing ring 214 is installed on the left side of the filter element 213. Specifically, water flows through the water pipe 11 and first enters the filter element 213, where large particles of impurities are intercepted. Then, it flows into the filter element 211 for secondary filtration, achieving graded interception of impurities. Finally, two valves 312 are opened to discharge the filtered fire-fighting water, preventing critical equipment such as sprinkler heads and fire pumps from failing due to impurities, and ensuring a rapid response of the fire protection system in the event of a fire.

[0042] Among them, the support ring 212 contacts the top of the housing 1 and supports the filter element 211.

[0043] The disassembly assembly 22 includes two mounting plates 221 on the top of the second filter element 213. A sealing cover 222 is provided on the top of the mounting plate 221. A slot 223 is opened on the top of the sealing cover 222. A bolt 224 is installed on the top of the sealing cover 222.

[0044] The mounting plate 221 is adapted to the slot 223, and the mounting plate 221 supports the filter element 213. The left side of the filter element 213 is V-shaped, and the V-shaped sealing ring 214 is V-shaped.

[0045] The connecting assembly 31 includes two connecting pipes 311 installed on the right side of the housing 1. Valves 312 are installed on the outer surface of the two connecting pipes 311. Flanges 313 are installed on the right side of the two connecting pipes 311. Flanges 314 are provided on the right side of the two flanges 313.

[0046] Among them, flange 2 313 is in contact with flange 3 314, and connecting pipe 1 311 is connected to shell 1.

[0047] The sealing assembly 32 includes a sealing ring 321 installed on the inner wall of the connecting pipe 311, and bolts 322 installed on the side of the two flanges 314 away from the flange 313. Connecting pipes 323 are installed on the inner walls of both flanges 314. Specifically, when the filter elements 211 and 213 need to be cleaned, the sealing cover 222 is removed by loosening bolts 224. The mounting plate 221 is then held, and the filter element 213 is pulled out of the filter element 211. The support ring 212 is then held, and the filter element 211 is removed from the housing 1 as a whole. The filter element 211 and 213 are then cleaned and reinstalled, ensuring that the filter is always in good working condition and reducing the time and labor costs required for maintenance.

[0048] Among them, the sealing ring 321 is in contact with the second connecting pipe 323 and the first connecting pipe 311 respectively.

[0049] A specific application of this embodiment is as follows: In use, flange 314 is first connected to flange 213 via bolt 322. Since flange 213 is fixedly connected to connecting pipe 111 and connecting pipe 223 is fixedly connected to flange 314, when flange 314 is connected to flange 213, connecting pipe 223 will squeeze sealing ring 321. At this time, the area of ​​sealing ring 321 increases, sealing the connection between connecting pipe 223 and connecting pipe 111. Then, flange 12 is connected to the fire pipeline. Subsequently, water flows into filter element 213 from water pipe 11. Large particles and impurities will be retained inside filter element 213 and then flow into filter element 211. At this time, the water undergoes secondary filtration through filter element 211, realizing the graded interception of impurities in fire water. Then, the two valves 312 are opened to discharge. When the filter elements 211 and 213 need cleaning, the user first loosens bolts 224. After all four bolts 224 are removed, the sealing cover 222 is removed. Then, the user holds the mounting plate 221 and pulls the filter element 213 out of the filter element 211. Next, the user holds the support ring 212 and pulls out the filter element 211 for cleaning. Then, the user puts the filter element 211 back into the housing 1. At this time, the support ring 212 contacts the housing 1. Then, the user puts the filter element 213 into the support ring 212, and the V-shaped sealing ring 214 seals the V-shaped opening of the filter element 211. At the same time, the mounting plate 221 contacts the bottom of the support ring 212. Then, the user aligns the groove 223 at the bottom of the sealing cover 222 with the mounting plate 221 and inserts it. Finally, the user connects and seals the support ring 212, the mounting plate 221, and the sealing cover 222 with several bolts 224.
