Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, and in particular to a high-rise fire-fighting equalizing water pipe. Background Technology

[0002] Fire protection water supply systems in high-rise buildings are a crucial component in ensuring building fire safety. Due to the significant height difference in high-rise buildings, the fire protection piping system generates substantial static water pressure, which can easily lead to excessive pressure in the lower zones of the system and insufficient pressure in the higher zones when water is used. This presents challenges to the design and stable operation of the fire protection system.

[0003] Currently, the industry typically uses methods such as zoned water supply, pressure reducing valves, or intermediate water tanks to address uneven pressure. However, these methods often have limitations such as system complexity, large space requirements, or delayed adjustment response.

[0004] It is necessary to provide a device with a relatively integrated structure that can autonomously respond to changes in pipeline pressure and perform targeted pressurization. Utility Model Content

[0038] The embodiments of this utility model will be described in detail below.

[0039] This utility model embodiment discloses a high-rise fire-fighting pressure equalization water pipe.

[0040] This utility model, through the structure of setting an outlet 11 and an inlet 12 on the basic pipeline 1, can form multiple water intake and injection nodes along the pipeline, providing a structural basis for local pressure regulation. The booster system 2 includes a booster pump 21, a water pressure sensor 22, and a controller, which are electrically connected to form a closed-loop control circuit. This allows the system to monitor pipeline pressure changes in real time and automatically start the booster program when the detected pressure is lower than a set threshold, pumping water from the downstream outlet 11 to the upstream inlet 12, thereby achieving automatic compensation and stabilization of pipeline pressure. The specific details are as follows:

[0041] The high-rise fire-fighting equalizing water pipe provided in this embodiment of the utility model has a base pipe 1 made of high-pressure resistant galvanized steel pipe or stainless steel pipe, which serves as the main channel for transporting fire-fighting water. An outlet 11 and an inlet 12 are provided on the base pipe 1. The outlet 11 leads the water in the pipe to the pressurization system, and the inlet 12 re-injects the pressurized water into the pipe. The outlet 11 and inlet 12 are connected to the base pipe 1 by welding or flange connection, with an inner diameter of 50mm and a wall thickness of 3-5mm. In this embodiment, both the outlet 11 and inlet 12 are circular interfaces, with their opening direction forming a 90-degree angle with the pipe axis. In other embodiments, the outlet 11 and inlet 12 can also adopt elliptical or square interfaces, and the opening angle can be adjusted within the range of 45-135 degrees according to installation requirements.

[0042] The booster system 2 includes a booster pump 21, a water pressure sensor 22, and a controller.

[0043] The function of the booster system 2 is to monitor and regulate the water pressure within the foundation pipe 1. The booster pump 21 is a vertical multistage centrifugal pump with a head range of 10-30m, and its function is to provide water pressure boosting. The inlet of the booster pump 21 is connected to the outlet 11 of the foundation pipe 1 via a galvanized steel pipe, with a pipe length of 1-3m and a diameter of 50mm; the outlet of the booster pump 21 is connected to the inlet 12 of the foundation pipe 1 via a galvanized steel pipe, with a pipe length of 1-3m and a diameter of 50mm.

[0044] The water pressure sensor 22 is a piezoresistive pressure sensor, used to monitor changes in water pressure within the pipeline in real time. The water pressure sensor 22 is installed on the inner wall of the base pipe 1, near the inlet 12, via a threaded connection. Its signal output terminal is electrically connected to the signal input terminal of the controller via a shielded cable. The angle between the sensing end face of the water pressure sensor 22 and the axis of the base pipe 1 is 45°. This angle helps reduce the influence of fluid flow on the measurement results and improves the accuracy of pressure measurement; in other embodiments, this angle can also be set to 30° or 60°.

[0045] The controller employs a pressure switch or a controller with a comparator circuit, and its function is to automatically control the start and stop of the booster pump 21 according to the set pressure value. The controller's control signal output terminal is electrically connected to the motor of the booster pump 21 via a power cable. The controller has an internally set pressure threshold, which can be adjusted within the range of 0.2-1.5 MPa as needed.

[0046] The water pressure sensor 22, the controller, and the motor of the booster pump 21 are electrically connected to form a closed-loop control circuit. When the water pressure detected by the water pressure sensor 22 is lower than the set value, the controller controls the booster pump 21 to start, pumping water from the outlet 11 to the inlet 12. This closed-loop control mechanism utilizes the principle of negative feedback, maintaining the pipeline pressure within the set range through real-time monitoring and adjustment.

[0047] In this embodiment, the basic pipeline 1 is provided with two outlets 11 and two inlets 12, and two sets of booster systems 2 are correspondingly provided; the distance between the outlets 11 and the inlets 12 is 15m. In other embodiments, depending on the pipeline length and pressure requirements, the basic pipeline 1 may also be provided with three or four outlets 11 and inlets 12, and multiple sets of booster systems 2 may be configured accordingly. The distance between the outlets 11 and inlets 12 can be adjusted within the range of 10-25m. The outlets 11 and inlets 12 connected to each set of booster systems 2 are arranged in a staggered distribution along the length of the basic pipeline 1. This arrangement helps to achieve balanced regulation of pipeline pressure and avoid pressure dead zones.

[0048] Furthermore, the inlet of the booster pump 21 in any booster system 2 is connected to the outlet 11 of a basic pipe 1 via a pipe, and the outlet of the booster pump 21 is connected to the inlet 12 of the basic pipe 1 via a pipe. This independent connection method allows each booster unit to operate independently, improving the reliability and maintainability of the system. The head loss corresponding to the pipe length between the outlet 11 and the inlet 12 connected to the booster pump 21 of any booster system 2 is 15m. Since the head loss is related to factors such as pipe length, pipe diameter, and pipe wall roughness, the head loss can be kept within the required range by controlling these parameters. In other embodiments, the head loss can also be set to 10m or 18m, but the basic requirement of not less than 10m should be guaranteed, and the corresponding pipe length adjustment range is 8-25m.

[0049] Overall, this invention combines a basic pipeline 1 with a booster system 2: the outlet 11 and inlet 12 on the basic pipeline 1 are connected to the booster pump 21, and the water pressure sensor 22 is electrically connected to the controller to form a closed-loop control. These structural features, combined, enable automatic monitoring and regulation of pipeline pressure to a certain extent, providing relatively stable water pressure in high-rise building fire water supply systems and having a positive effect on improving the reliability of fire water supply. Furthermore, by setting up multiple booster systems 2 in a staggered distributed arrangement, and ensuring sufficient head loss and appropriate sensor installation angles, the combination of these technical features allows the system to adapt to pressure regulation needs under different operating conditions, which also helps optimize system performance. Each booster unit is independently connected, which improves the modularity of the system to a certain extent, facilitating maintenance and troubleshooting.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
