Abstract: The cold north of China and the municipal fire districts are using underground water supply facilities Fire Hydrant Built form, although to some extent to meet the city fire protection water supply problems, but due to climatic reasons, there are still a lot of inconvenience to use the winter, mainly difficult to find, not easy to open operation, not easy to add water, which to some extent, will affect the speed of fire fighting. Based on the Fire Cape Characteristics analysis and installation, maintenance and other aspects of this paper discussed the construction of fire universal significance and necessity of water cranes.
Keywords: Crane feature set fire water management
In Northeast China, Northwest Territories, frozen long time, taking into account the freezing problem, municipal Fire Hydrant Underground fire hydrants are installed using the form, but mostly located in the road next to the road but on the often snow bury and often difficult to find the cause set position, the fire covers difficult issues such as forced open, even if the covers can be opened quickly , due to take to bring underground water, the operation is extremely inconvenient, and this will greatly affect the fire fighting and rescue, fire protection products in recent years as China's research and innovation, we found that the fire water crane can avoid many disadvantages of underground fire hydrant, in the northern cold regions Alternative outdoor underground fire hydrant.
1 fire water features Crane 1.1 Fire Cape has a good frost function, its discharge valve and water valve forms of linkage, when the fire water supply to the valve open, outlet valve is closed linkage to begin water, when water supply is completed, close the water supply valve, while opening outlet valve linkage, enabling the remaining riser before the rapid discharge of water in the ice off, preventing the riser in the water freezes over. -40 C can be used under cold temperatures.
1.2 Fire Cape and the link with the worm drive transmission designed and launched a nozzle from side to side with the 0-100 degrees, 0-300mm stretching before and after the function, which facilitates the Fire The stop adding water.
1.3 Fire Cape traffic in the city water system, water injection case 0.4Mpa reach 5-6m3/min, ground fire hydrants can be installed features, both for the relay of fire use water and the nearest fire, but also convenient Fire Water supply.
1.4 Fire Water crane structure is reasonable, the main control unit, such as the valve body, stem nut and other components using the copper material to ensure that the various components is not rust, improve equipment reliability, convenient maintenance .
1.5 Fire Water crane using the new glass steel shell, lightweight high strength without metal reinforcement, with the next in direct sunlight without expansion, no contraction in the cold climate, anti-aging, long service life, fine and smooth surface can be painting a variety of coatings, anti-clean, not fade, can also be made in various shapes, enhancing the city beautiful.
