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 sadinto 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:Why is the fire hydrant drain valve leaking?
Valve leakage water leakage and leakage, internal leakage is the main valve closed in place, sealing surface of a foreign case, damage to the sealing surface.Leakage is due to valve, hand wheel, filler or flange cushion broken, lack of bolt tension caused by leakage.
Q:Can the test hydrant of single building be used for fire fighting simultaneously?
No see authoritative explanation, according to previous interpretations, the test fire hydrant located in the roof in the experiment, but also useful for other building near the fire control and fire extinguishing function, personally think that the hose and lance configuration complete, fire hydrant test of single storey buildings (no roof) can do fire extinguishing. Want to clear up, and the local fire department in consultation, too troublesome to do one, no big event.
Q:What is outdoor hydrant water supply system?
High pressure water supply network. Refers to the pipe network often maintain sufficient pressure, the fire does not need to use fire engines or other mobile pumps pressurized, and directly from the fire hydrant out of the water hose, fire fighting. When the building height is less than or equal to 24m, high pressure water supply pipeline outdoor pressure should ensure the production, life, fire water to reach the maximum, and the highest water layout in the protection range of any building, gun full water column should not be less than 10m. When the building height is greater than 24m, the fire fighting equipment should be based on indoor fire fighting equipment.
Q:Who knows how the fire hose works in the indoor hydrant?
Why don't you play with that?! You can be held in jail during the crackdown. Let's see how other fire hoses are made. The question is not how to make them beautiful, but what to do on the surface. Let's make a fool of the past!
Q:Does the hydrant shift require the whole system to drain off water?
Is generally not needed, in the fire hydrant system network, design of the valve, as long as the fire hydrant to be shifted off the corresponding water supply pipe valve can be placed on the realization of local water hydrant maintenance or displaced.
Q:What are the three outdoor fire hydrants for?
The same two port is 65, then the fire hose, can also be mixed with water to the fire, big mouth is 100 and to the fire with water, with less use of the outdoor fire hydrant is the most important to the fire with water.
Q:Is there any hidden danger of fire hydrant?
(1) the disposition and establishment of fire control facilities, equipment or fire safety signs do not conform to the state standards or industry standards, or have not been kept in good condition and effective;From the management point of view, I do not know the fire facilities are bad, or know that the bad, not repaired, indicating that there is a problem managementSo this is definitely hidden trouble
Q:Outdoor fire hydrant distance from the roadside should not be greater than the number of meters?
The outdoor fire hydrant is used for fire engines, therefore, the protective radius of the fire engine is the protective radius of the fire hydrant, and the maximum water supply distance (i.e. the radius of protection) of the fire engine is 150m, so the protective radius of the fire hydrant is 150m.
Q:Buy a house, the door of fire hydrants (fire extinguishers) good, or at the entrance to the distribution box (radiation)?
The hydrant is a little better. After all, use is not very frequent. Fire hydrants must be free of electricity or radiation. The disadvantage is that the use of space may be occupied, the other is in the event of fire, your home may be flooded; distribution box is relatively high, the frequency of use, another is where the electricity will inevitably exist danger. What the radiation does not estimate, civil electricity which have so much radiation, how much radiation is the high-voltage tower?.
Q:What's the difference between the manual alarm button and the fire hydrant button?
The difference between the fire hydrant button and the manual fire alarm button is that one alarm is used and the other is used for starting the equipment.
