Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a fire fighting pump station with a prefabricated valve well. Background Art

[0002] As the height and density of urban buildings increase, the requirements for fire safety also increase. Fire pump stations, as an important part of urban fire protection systems, are responsible for providing stable and high-pressure water flows when fires occur. However, in traditional fire pump stations, pumps, drivers and related valves are often placed in different locations, which results in firefighters needing to move between multiple points to open or close valves in an emergency, wasting valuable time and increasing the complexity of operations. During the installation of valves and pipelines, a lot of on-site work is usually required, including excavation work, pipeline layout and concrete foundation laying, which not only increases the total cost of the project, but also prolongs the installation cycle and affects the rapid deployment of the pump station. In addition, since valves and related equipment are distributed in different parts of the pump station, maintenance is often difficult, especially in severe weather or complex environments, where inspection and maintenance operations become more arduous. At the same time, valves and pipelines are often in a damp environment, susceptible to corrosion and damage, affecting the reliability and service life of the entire pump station system.

[0003] Therefore, in order to overcome the limitations of the existing technology and improve the performance of fire pump stations, there is an urgent need for a new type of fire pump station design that can effectively avoid external corrosion, integrate various fire protection components, and facilitate maintenance and use by staff. Therefore, it is very necessary to involve a fire pump station with a prefabricated valve well for use in the existing field of fire equipment technology. Utility Model Content
