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.

Q:How to solve the problem of unreasonable fire hydrant location?
Look at the house design and make sure who issues it. But you just have to find developers.
Q:The main fire hydrant in the basement is connected to the municipal water supply pipe directly. Is there a fire pump and a fire pool?
Should be set, according to the building fire code, fire hydrant water consumption is greater than 15L/s, and there is no suitable alternative water sources, we should set fire pool. In addition to the underground garage located indoor fire hydrant to set a sprinkler system, must be more than 15L/S, so it must be. A fire pump is pressurized into the water in a fire pool. Connection order is: municipal water supply - fire pool - fire pump - fire water supply dry pipeOf course, the fire pool, which is also equipped with liquid level control valves and other accessories.The fire pool is not flat, but tends to slope towards the direction of the suction of the pump. And the water pump absorption tube is usually L type, in order to facilitate the collection of water, so in the pool suction section should be set sink to facilitate water pump suction.
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 indoor fire hydrant box position be changed?
Be familiar with the drawings, check whether the reserved holes are correct, check the pipe, pipe fittings, valves, fire hydrant boxes, etc., whether it meets the design requirements and quality standards.
Q:How does the fire hydrant box identify the left and right doors?
According to the site decision, the main decisive factor is the bolt opening, that is to say, the direction of the inlet pipe!
Q:Can the water in the fire hydrant be used?
You are wrong, the fire hydrant water is fire station fire, not residential, nor property. If he tells you, it's really a bit of a problem. But some things are Human effort is the decisive factor. Fire hydrant water really can not be used indiscriminately
Q:How can fire water tank be connected with fire hydrant and spray pipe?
In addition to the connection between the pressure stabilizing equipment and fire hydrant system and sprinkler system, the fire water tank must be directly connected with hydrant system and sprinkler system. You'd better download a blueprint to see if the text is unclear.
Q:Fire hydrant system composition and working principle?
By the fire hydrant system, fire hydrant pipe (fire hydrant box, fire with fire hose reel, fire water, fire hydrant and buzzer valve), booster pump, fire pump, fire water tank (underground fire pool and surface fire pool), outdoor fire hydrant (i.e. ground fire hydrant, fire hydrant, fire hydrant button adapter) (i.e. pump start button), etc..
Q:Fire pipes can be installed in owner hygiene? And is the root of the 50 ppR tube?.
PP-R also called type three polypropylene pipe and is also called the PP-R pipe or PPR pipe, with energy saving, environmental protection, high strength, corrosion resistance, with smooth inner wall has the advantages of scale, construction and easy maintenance, long service life, widely used in building water supply and drainage, urban water supply and drainage, city gas electric and optical cable sheath, industrial fluid transportation, agricultural irrigation construction, municipal, industrial and agricultural fields. The PP-R pipe is made of random copolymerized polypropylene and is extruded into tubes to be molded into tubes.
Q:How can the vertical fire hydrant be properly closed?
When the vertical fire hydrant is closed, unless the at least one discharge valve is slightly opened, the executing parts are damaged, and the shutoff valve of the vertical fire hydrant is completely damaged.
