Product Description:

We make different styles of indoor hydrant, landing hydrant, underground hydrant,etc.

1. Item: SNJ 65

2. Type:SN50,SN65

3. Strength test pressure:2.4mpa

4. The indoor fire hydrant is a fixed indoor fire-fighting equipment in factories, public buildings, warehouse,etc.

Indoor fire hydrant is the connecter in the water piping network, including one valve with single outlet, One Valve with double outlet and double valve with double outlet etc. It's used to offer assistance to control the fire.

Rated working pressure:16 Bar

Strength test pressure:24Bar

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.

Even twist the handle of the switch. The anti-collision hydrant can open and close quickly and flexibly under any circumstances.
Q:How is the temporary water pipe line arranged on the construction site, and how is the fire hose line arranged? How big is the diameter?
Fire water meter of the caliber is generally 100MM, 75MM, 50MM three kinds, each has gate wells, to correspond to different buildings. The theory on the number, the greater the diameter. Each layer of high-rise buildings have fire interface, low layer building is a fire interface, usually in front of the building or buildings, some commercial buildings should install automatic fire sprinkler device, installed by tap water engineering company, the fire department approval before completion. The other is not to open fire as he used.
Q:Fire hydrant power failure is how to use the fire pump useful trouble detailed answer
