Description

Technical Field

[0001] This utility model belongs to the field of pipeline exhaust technology, and in particular relates to a fire-fighting pipeline with automatic exhaust function. Background Technology

[0002] In modern fire protection systems, fire pipelines serve as the "lifeline" for transporting fire extinguishing media, and their operational status directly determines the success or failure of fire suppression. With the rapid development of the construction industry, complex buildings such as high-rise office buildings, large commercial complexes, and underground transportation hubs are emerging in cities. The fire pipeline systems of these buildings are large in scale and complex in structure, with pipeline lengths often reaching thousands of meters and crisscrossing layouts. During installation, commissioning, routine maintenance, or long-term use, air can easily enter the interior of fire pipelines, forming airlocks, which has become a common problem in the operation of fire protection systems.

[0003] Currently, fire-fighting pipelines typically require manual air venting. However, the large number and wide distribution of manual air vents make management difficult. Managers struggle to accurately monitor the working status and venting time of each vent, leading to missed inspections and venting, significantly increasing labor costs and hindering comprehensive and effective management and maintenance of the fire-fighting pipeline system. Therefore, we propose a fire-fighting pipeline with automatic air venting function. Utility Model Content

[0004] The purpose of this invention is to provide a fire-fighting pipeline with automatic venting function. Specifically, by setting up an venting mechanism, water flow pushes air inside the fire-fighting pipeline into the protective shell through a connecting pipe. Due to the water pressure difference on both sides, the gas is preferentially discharged, with a small amount of water discharged along with the gas. The float ball moves upward due to buoyancy, causing the sealing component to close the venting channel and preventing further water flow. After the drain valve closes, the water level drops, the float ball moves downward, the venting channel reopens, and air enters the pipeline, completing the automatic venting. This ensures water flow efficiency and saves on manual operation, solving the problem that existing fire-fighting pipelines typically require manual venting. However, manual venting valves are numerous and widely distributed, making management difficult. Managers struggle to accurately grasp the working status and venting time of each valve, easily leading to missed inspections and venting, significantly increasing labor costs, and hindering comprehensive and effective management and maintenance of the fire-fighting pipeline system.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a fire-fighting pipeline with automatic exhaust function, comprising a fire-fighting pipeline, a drain valve installed on the left side of the fire-fighting pipeline, and further comprising:

[0007] An exhaust mechanism, located on the outer surface of the fire duct, is used to vent air from the inside of the fire duct.

[0008] A filtration mechanism is located on the left side of the exhaust mechanism and is used to filter the water inside the fire-fighting pipeline.

[0009] Furthermore, the exhaust mechanism includes a connecting assembly for connecting the fire extinguishing pipe to the exhaust mechanism.

[0010] An exhaust assembly for automatically discharging air.

[0011] Furthermore, the filtration mechanism includes a mounting assembly mounted on top of the filtration mechanism, the mounting assembly being used for installation and removal.

[0012] Furthermore, the connecting assembly includes a connecting pipe one installed on the fire-fighting pipeline, a connecting pipe two threadedly connected to the inner wall of the connecting pipe one, a protective shell installed on the top of the connecting pipe two, and a hollow shell installed on the top of the protective shell;

[0013] The hollow shell has four vent holes on its outer surface and an annular groove on the inner wall of its top.

[0014] Furthermore, the exhaust assembly includes an annular plate disposed inside the protective shell. Support legs are installed on the bottom left and right sides of the annular plate, a float is disposed on the top of the annular plate, limit rods are installed on the left and right sides of the float, sliding grooves are opened on the left and right sides of the protective shell, a fixing block is installed on the top of the float, a sealing ring is installed on the top of the fixing block, and a sealing plug is installed at the center of the top of the fixing block.

[0015] Both of the limiting rods are slidably connected to the sliding grooves, and the two sliding grooves limit the movement of the two limiting rods.

[0016] Furthermore, the filtration mechanism includes a filter housing fixedly connected to the fire-fighting pipeline, and a filter element is disposed inside the filter housing;

[0017] The top of the filter element contacts the top of the filter housing, and the filter housing limits the position of the filter element.

[0018] Furthermore, the mounting assembly includes a sealing cap disposed on top of the filter element, and four bolts are mounted on the top of the sealing cap;

[0019] The sealing cap is in contact with the filter element, and the bolt limits the position of the sealing cap.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model features an exhaust mechanism. Specifically, the water flow pushes the air in the fire-fighting pipeline into the protective shell through the connecting pipe. Due to the water pressure difference on both sides, the gas is discharged first, and a small amount of water is discharged with the gas. The float moves upward due to buoyancy, which drives the sealing component to close the exhaust channel and prevent water from continuing to flow out. After the drain valve is closed, the water level drops, the float moves downward, the exhaust channel reopens, and air enters the pipeline, completing the automatic exhaust. This ensures water flow efficiency and saves manual operation.

[0022] 2. This utility model incorporates a filtration mechanism. Specifically, the fire-fighting pipeline is connected to the fire-fighting water pipe, and water is injected by opening the drain valve. When the water flows through the filter element, impurities such as mud, sand, and rust are intercepted. To clean the filter element, the bolts are unscrewed, the sealing cap is removed, and the filter element is pulled out. After cleaning, the filter element is reinserted, the sealing cap is replaced, and the filter element is secured with bolts. This effectively prevents impurities from clogging the sprinkler heads, ensuring that the fire-fighting equipment can output water normally during a fire, improving fire-fighting efficiency, and reducing maintenance costs.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0033] Please see Figures 1-5 As shown, this utility model is a fire-fighting pipeline with automatic exhaust function, including a fire-fighting pipeline 1, a drain valve 11 installed on the left side of the fire-fighting pipeline 1, and further including:

[0034] Exhaust mechanism 2 is installed on the outer surface of fire hydrant 1 and is used to exhaust air from the inside of fire hydrant 1.

[0035] The filter mechanism 3 is located on the left side of the exhaust mechanism 2 and is used to filter the water inside the fire pipe 1.

[0036] The exhaust mechanism 2 includes a connecting assembly 21, which is used to connect the fire hydrant 1 to the exhaust mechanism 2.

[0037] Exhaust assembly 22, which is used to automatically exhaust air.

[0038] The filter mechanism 3 includes a mounting component 32, which is mounted on the top of the filter mechanism 3 and is used for installation and removal.

[0039] The connecting assembly 21 includes a connecting pipe 211 installed on the fire pipe 1, a connecting pipe 212 threadedly connected to the inner wall of the connecting pipe 211, a protective shell 213 installed on the top of the connecting pipe 212, and a hollow shell 214 installed on the top of the protective shell 213.

[0040] The hollow shell 214 has four vent holes 215 on its outer surface, and the protective shell 213 has an annular groove 216 on its top inner wall.

[0041] The exhaust assembly 22 includes an annular plate 221 disposed inside the protective shell 213. Support legs 222 are installed on the left and right sides of the bottom of the annular plate 221. A float 223 is disposed on the top of the annular plate 221. Limit rods 224 are installed on the left and right sides of the float 223. Sliding grooves 225 are opened on the left and right sides of the protective shell 213. A fixing block 226 is installed on the top of the float 223. A sealing ring 227 is installed on the top of the fixing block 226. A sealing plug 228 is installed at the center of the top of the fixing block 226. Specifically, the water flow pushes the air in the fire pipe 1 into the protective shell 213 through the connecting pipe. Due to the water pressure difference on both sides, the gas is discharged first, and a small amount of water is discharged with the gas. The float 223 moves upward due to buoyancy, which drives the sealing assembly to close the exhaust channel and prevent water from continuing to flow out. After the drain valve is closed, the water level drops, the float moves down, the exhaust channel reopens, and air enters the pipe, completing the automatic exhaust. This ensures water flow efficiency and saves manual operation.

[0042] Both limiting rods 224 are slidably connected to the slide grooves 225, and the two slide grooves 225 limit the two limiting rods 224.

[0043] The filtration mechanism 3 includes a filter housing 31 fixedly connected to the fire-fighting pipeline 1, and a filter element 311 is provided inside the filter housing 31.

[0044] The top of the filter element 311 contacts the top of the filter housing 31, and the filter housing 31 limits the position of the filter element 311.

[0045] The mounting assembly 32 includes a sealing cover 321 located on top of the filter element 311, with four bolts 322 installed on the top of the sealing cover 321. Specifically, the fire pipe 1 is connected to the fire water pipe, and the drain valve 11 is opened to inject water. When the water flows through the filter element 311, impurities such as mud, sand, and rust are intercepted. When cleaning the filter element, the bolts 322 are unscrewed, the sealing cover 321 is removed, and the filter element is pulled out. After cleaning, the filter element is reinserted, the sealing cover is closed, and it is secured with bolts. This effectively prevents impurities from clogging the sprinkler heads, ensures that the fire-fighting equipment can output water normally during a fire, improves fire-fighting efficiency, and reduces maintenance costs.

[0046] The sealing cap 321 contacts the filter element 311, and the bolt 322 limits the sealing cap 321.

[0047] A specific application of this embodiment is as follows: In use, first connect the fire pipe 1 to the fire water pipe, then open the drain valve 11. Water flows into the fire pipe 1 and simultaneously into the filter element 311, where impurities are intercepted. When the filter element 311 needs cleaning, the user can first loosen the bolts 322, then remove all bolts 322, remove the sealing cover 321, and pull the filter element 311 out of the filter housing 31 for cleaning. After cleaning, the filter element 311 can be reinserted into the filter housing 31. Then, place the sealing cap 321 on top of the filter element 311 and re-secure it with bolts 322. This prevents solid impurities such as mud, rust, and welding residue in the water from clogging the sprinkler head, reducing maintenance costs. The water continues to flow, pushing the air inside the fire pipe 1. When the water reaches the bottom of connecting pipe 1 211, water and air enter the protective shell 213 through connecting pipe 212. At this point, the water level on both sides of the float 223 is higher than the water level at the bottom of the float 223. Since the water level on both sides is higher than in the middle, the water on both sides will carry the air and the protective shell... The gas inside 213 is first expelled from the protective shell 213, then discharged into the hollow shell 214 through the top slot, and finally discharged through the vent 215. At this time, a small amount of water will also be discharged through the vent 215. Under the buoyancy of the water, the float 223 will float. Due to the limitation of the slide groove 225, the float 223 can only float vertically. As the float 223 slowly floats, the top fixing block 226 will move upward with the float 223. At the same time, the fixing block 226 will drive the sealing ring 227 and the sealing plug 228 to move upward. At this time, the sealing ring 227 will be embedded in the annular ring. The water is sealed in the groove 216, and the sealing plug 228 is inserted into the groove at the top of the protective shell 213 to block the water inside the protective shell 213. When the drain valve 11 is closed, as the water slowly recedes, the float 223 will slowly move downward with the water. At this time, the float 223 drives the fixed block 226 to move downward, and at the same time drives the sealing ring 227 and the sealing plug 228 to move downward. As the sealing plug 228 and the sealing ring 227 move downward, the gas enters the fire pipe 1 through the exhaust hole 215 to realize automatic exhaust, ensure the efficiency of fire water flow, and greatly save the cost of manual operation.
