 s


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, instantaneous "quick" connector 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.

Q:What does hydrant SN65 mean? SN refers to the interior? But there are plenty of them outside
The rotary hydrant is an indoor hydrant with a horizontal rotation of 360 degrees relative to a base connected with a water inlet pipe. The utility model has the characteristics of relative rotation between the bolt body and the base, so that the utility model can be arranged in the ultra-thin box body, so that the box body thinning is possible. When the fire hydrant is not used, the water outlet of the plug body can be rotated to a parallel state with the wall, and the box door can be closed; when the utility model is used, the water outlet of the plug body is screwed out and is vertical to the wall body, and the water hose can be connected with the water pipe, so that the operation is convenient.
