This paper discusses the design scheme of fire hydrant system of Barudyu Bay professional Football Field project in Dalian,Liaoning province in cold winter area.The wet fire hydrant system has problems such as freezing and water leakage in winter.If the conventional wet system needs to adopt a large amount of electric tracing heat preservation,there are certain potential accidents.This design uses dry and wet alternating conversion system,electric valve control dry system quick open and close function,open time should not exceed 30 s,and meet the specification of 5 min water filling time requirements,to achieve dry and wet system alternating conversion,wet in summer,dry in winter,the system runs eco-nomically,reasonably,safely and reliably.
