Description
Technical Field
[0001] This utility model relates to the field of heating, ventilation, air conditioning (HVAC) engineering, and more specifically, to a leak-proof device for HVAC and fire protection engineering systems. Background Technology
[0002] In modern building systems, HVAC and fire protection systems are indispensable core components ensuring building safety and comfortable operation. HVAC systems play a crucial role in regulating the indoor environment, creating a suitable living and working environment by precisely controlling temperature, humidity, and air circulation, greatly improving the comfort of living and working. Fire protection systems, on the other hand, are the last line of defense for building safety. In emergencies such as fires, they can respond quickly, effectively control the spread of fire, buy precious time for evacuation and fire rescue, and maximize the protection of lives and minimize property damage. However, traditional HVAC and fire protection systems' anti-leakage devices still have the following shortcomings:
[0003] Traditional HVAC and fire protection systems often use a single-layer discharge pipe. Because there is only one layer, in the event of a leak, there are no other layers to prevent or buffer the spread of substances, leading to rapid diffusion of the leaked material, expanding the contamination area, increasing the severity of the accident and the difficulty of handling it. Furthermore, connection areas are critical points prone to leakage. During long-term use, factors such as vibration and temperature changes can cause these connections to loosen, resulting in incomplete sealing and ultimately leaks. Therefore, a leak-proof device for HVAC and fire protection systems is proposed. Utility Model Content
[0004] The purpose of this invention is to address the problem that traditional HVAC and fire protection engineering systems often use a single-layer discharge pipe. Because there is only one layer, in the event of a leak, there are no other layers to block or buffer the spread of the leaked material, leading to rapid spread of the contaminant, increasing the severity of the accident and the difficulty of handling it. Furthermore, the connection areas are critical points prone to leakage. During long-term use, factors such as vibration and temperature changes can cause the connections to loosen, resulting in poor sealing and leaks. This invention provides a leak-proof device for HVAC and fire protection engineering systems to solve the problems mentioned in the background.
[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0006] The present invention is as follows: a leak-proof device for a heating, ventilation and fire protection engineering system, comprising a main pipe, wherein the outer wall of the main pipe is provided with a leak-proof component to prevent seepage, and the inner wall of the main pipe is provided with a detection component to detect seepage gas.
[0007] The anti-seepage component includes multiple partitions fixedly connected to the outer wall of the main pipe. A fixed pipe is fixedly connected to the side of the multiple partitions away from the main pipe. Two side pipes are fixedly connected to the outer wall of the main pipe. A connecting pipe is provided at the end of each of the two side pipes away from the main pipe. A first clamp and a second clamp are provided on the outer wall of the two side pipes and the connecting pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. By setting up anti-permeability components, a highly efficient anti-permeability effect is achieved at the connection points. Through the cooperation of the baffle and the fixed pipe, the diffusion of the leakage material from the main pipeline is effectively blocked, reducing the impact of leakage on the surrounding environment. Through the cooperation of the first clamp and the second clamp, the connecting pipe and the side pipe are tightly fitted to prevent the leakage material from spreading outward.

[0016] 2. The detection components enable rapid detection of the outer wall of the main pipeline.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0027] like Figure 1 As shown, this embodiment proposes a seepage prevention device for a heating, ventilation and fire protection engineering system, including a main pipe 1, an anti-seepage component 2 for preventing seepage is provided on the outer wall of the main pipe 1, and a detection component 3 for detecting seepage gas is provided on the inner wall of the main pipe 1.
[0028] like Figure 2 and Figure 3As shown, the anti-seepage component 2 includes multiple baffles 201 fixedly connected to the outer wall of the main pipe 1. A fixed pipe 202 is fixedly connected to the side of each baffle 201 away from the main pipe 1. Through the cooperation of the baffles 201 and the fixed pipe 202, not only is the main pipe 1 effectively protected, but the component also prevents leakage from spreading outwards when the main pipe 1 leaks. Two side pipes 203 are fixedly connected to the outer wall of the main pipe 1. A connecting pipe 204 is provided at the end of each side pipe 203 away from the main pipe 1. The two side pipes 203 and the connecting pipe 204... The outer wall of pipe 204 is provided with a first clamp 205 and a second clamp 206, which stably fix the side pipe 203 and the connecting pipe 204. The outer wall of the first clamp 205 near the second clamp 206 is provided with a main sealing ring 207, and the inner wall of the second clamp 206 near the first clamp 205 is provided with an auxiliary sealing ring 208. The main sealing ring 207 and the auxiliary sealing ring 208 enhance the sealing of the connection and effectively prevent leakage at the connection. A protective structure is formed outside the main pipeline 1 by the partition 201 and the fixed pipe 202. When there are signs of leakage in the main pipeline 1, the partition 201 and the fixed pipe 202 can block some of the leaked material from spreading outward. The connecting pipe 204 and the side pipe 203 are stably fixed by the first clamp 205 and the second clamp 206. At the same time, the main sealing ring 207 and the auxiliary sealing ring 208 cooperate with each other to enhance the sealing of the connection and prevent leakage. This improves the sealing of the connection between the side pipe 203 and the connecting pipe 204, reduces the possibility of leakage at the connection, effectively blocks the spread of the leaked material in the main pipeline 1, and reduces the impact of leakage on the surrounding environment.
[0029] like Figure 4 As shown, the detection component 3 includes a humidity sensor 301 disposed on the inner wall of the fixed pipe 202, a protective cover 302 disposed on the outer wall of the fixed pipe 202, a controller 303 disposed on the inner wall of the protective cover 302, and an audible and visual alarm 304 disposed on the outer wall of the protective cover 302. The humidity sensor 301 detects the humidity between the fixed pipe 202 and the main pipe 1 in real time and transmits the signal to the controller 303. The controller 303 analyzes and processes the received signal, and when the humidity is detected to be high, it controls the audible and visual alarm 304 to sound an alarm. Both the humidity sensor 301 and the audible and visual alarm 304 are electrically connected to the controller 303. Humidity sensor 301 monitors the humidity between fixed pipe 202 and main pipe 1 in real time. When leakage occurs in main pipe 1 and the leaking material enters fixed pipe 202, causing a change in humidity, humidity sensor 301 transmits a signal to controller 303. After receiving the signal, controller 303 controls audible and visual alarm 304 to sound an alarm, reminding staff to handle the situation promptly. Protective cover 302 protects controller 303 and audible and visual alarm 304, thus enabling real-time and accurate detection of leakage in main pipe 1.
[0030] like Figure 4 As shown, a detection tube 4 is fixedly connected to the outer wall of the main pipeline 1, and a cap 5 is snapped onto the end of the detection tube 4 away from the main pipeline 1. The cap 5 seals the detection tube 4 to prevent external substances from entering. When it is necessary to test or sample the main pipeline 1, the cap 5 can be opened and the relevant operations can be performed through the detection tube 4, thereby reducing damage and impact on the main pipeline 1.
[0031] like Figure 5 As shown, valves 6 are installed on the inner walls of both side pipes 203, and handles 7 are installed on the top of both valves 6. By opening or closing the valves 6 through the handles 7, it is convenient to adjust the flow rate of the medium in the side pipes 203 or to completely block the flow of the medium, so as to quickly shut off the pipeline in an emergency and prevent the leakage from spreading.
[0032] like Figure 5 As shown, a first magnetic sealing strip 8 is provided on the inner wall of each connecting pipe 204 near the side pipe 203, and a second magnetic sealing strip 9 is provided on the inner wall of each side pipe 203 near the connecting pipe 204. When the connecting pipe 204 is connected to the side pipe 203, the first magnetic sealing strip 8 and the second magnetic sealing strip 9 attract each other and fit tightly together to form a sealing structure, preventing leakage at the connection point and greatly enhancing the sealing performance of the connection point.
[0033] like Figure 4 As shown, a turbine monitoring ring 10 is installed on the outer wall of the main pipeline 1, and the turbine monitoring ring 10 is electrically connected to the controller 303. When leakage occurs in the main pipeline 1, the flow state of the medium may change. The turbine monitoring ring 10 transmits the monitored signal to the controller 303, and the controller 303 controls the audible and visual alarm 304 to sound an alarm, reminding the staff to deal with it in time.
[0034] like Figure 2 As shown, a fixing plate 11 is fixedly connected to the inner wall of the protective cover 302, and a heat insulation cotton 12 is provided on one side of the fixing plate 11. The heat insulation cotton 12 can prevent external heat from entering the protective cover 302, reduce the temperature inside the protective cover 302, protect electronic components such as the controller 303 and the audible and visual alarm 304 from high temperature, and ensure their normal operation.
[0035] Specifically, when the anti-leakage device of this HVAC and fire protection engineering system is in use: a protective structure is formed outside the main pipe 1 by the partition 201 and the fixed pipe 202. When there are signs of leakage in the main pipe 1, the partition 201 and the fixed pipe 202 can block some of the leaked material from spreading outward. The connecting pipe 204 and the side pipe 203 are stably fixed by the first clamp 205 and the second clamp 206. At the same time, the main sealing ring 207 and the auxiliary sealing ring 208 cooperate with each other to enhance the sealing of the connection, prevent leakage, improve the sealing of the connection between the side pipe 203 and the connecting pipe 204, and reduce the possibility of leakage at the connection (e.g., Figure 2 and Figure 3 As shown); the humidity sensor 301 monitors the humidity between the fixed pipe 202 and the main pipe 1 in real time. When the main pipe 1 leaks and the leaking material enters the fixed pipe 202, causing a change in humidity, the humidity sensor 301 transmits a signal to the controller 303. Upon receiving the signal, the controller 303 activates the audible and visual alarm 304 to sound an alarm, reminding staff to handle the situation promptly. This allows for real-time and accurate detection of leaks in the main pipe 1 (such as...). Figure 4 (As shown); effectively prevents the spread of leaked material from the main pipeline 1, reducing the impact of leakage on the surrounding environment.
[0036] All technical features in this embodiment can be freely combined according to actual needs.
[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
