Technical Field
[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a multifunctional water hammer pressure relief device. Background Art
[0002] During firefighting operations, firefighters need to adopt different water supply and firefighting strategies for different fire scenarios. When fighting forest fires, since the fire may spread rapidly to complex terrain such as hillsides and cliffs, firefighters often need to lay water hoses vertically along these terrains to transport water directly to the fire scene. In this case, the water hoses are usually set at the bottom of the slope to ensure a stable water supply. However, due to the large terrain drop, the water flow drop also increases when the water supply is cut off, which may cause water hammer and damage the fire truck water pump. When fighting high-rise building fires, firefighters also face the challenge of laying water hoses vertically. Whether laying them vertically along the building's exterior wall or winding along the stairs, the stability and water supply efficiency of the water hoses need to be ensured. This is especially true for the water hose supply point set at the first floor entrance. As the starting point of the entire water supply system, its stability and reliability are crucial. Similar to forest fires, vertical water hoses in high-rise building fires also face the threat of water hammer when the water supply is cut off.
[0003] To meet these challenges, fire equipment manufacturers have developed fire equipment with a one-way valve. This one-way valve can effectively prevent water backflow based on the pressure difference, thereby preventing water hammer from damaging the fire truck water pump. In addition, the equipment is made of copper, which has the advantages of low manufacturing cost and good corrosion resistance. Copper has good corrosion resistance and can maintain the integrity and service life of the equipment in harsh environments. At the same time, the equipment is small in size and light in weight, making it easy for firefighters to carry and operate. These characteristics make the equipment widely practical and applicable in firefighting operations.
[0004] However, although this equipment performs well in many aspects, there are still some problems in the joint connection. For example, the joint connection is not fast and stable enough, which may affect the water supply efficiency or even cause the water hose to fall off in an emergency. For this reason, we propose a multifunctional anti-water hammer pressure relief device. Utility Model Content
