Model: SN 50 &SN65
CCCF CERTIFICATE

Indoor fire hydrants valve called fire plug in USA is a connector to fire water supply with the valve interface,  used for factory, warehouse, high-rise buildings, public buildings and ship . normally installed in fire hydrant box, with fire hoses and water gun or wait for equipment supporting the fire extinguishment.

A fire hydrant (also known colloquially as a fire plug in the United States or as a johnny pump in New York City, because the firemen of the late 19th century were called Johnnies ), is an active fire protection measure, and a source of water provided in most urban, suburban and rural areas with municipal water service to enable firefighters to tap into the municipal water supply to assist in extinguishing a fire.

Operation

A hose is attached to the fire hydrant, then the valve is opened to provide a powerful flow of water, on the order of 350 kPa (50 lbf/in²) (this pressure varies according to region and depends on various factors including the size and location of the attached water main). This hose can be further attached to a fire engine, which can then use a powerful pump to boost the water pressure and possibly split it into multiple streams. The hose may be connected with a threaded connection or a Storz connector. Care should be taken not to open or close a fire hydrant too quickly, as this can create a water hammer which can damage nearby pipes and equipment. The water inside a charged hoseline causes it to be very heavy and high water pressure causes it to be stiff and unable to make a tight turn while pressurized. When a fire hydrant is unobstructed, this is not a problem, as there is enough room to adequately position the hose.
