SNW65-I Red Indoor Fire Hydrant Valve


1. SNW65-I type indoor fire hydrant product is designed according to the requirements of GB3445-2005. Indoor Fire Hydrant standard. It maintains the appearance of ordinary indoor fire hydrants, standard interface forms, and traditional installation and operation methods. Pressure stabilization function, regardless of the difference in inlet pressure level, the pressure in the pipe network fluctuates and changes, and its outlet pressure can be reduced to stabilize at the use pressure value; when activated, turn the handwheel counterclockwise to open the valve flap, the pressure

2. After the water from the hydrant inlet passes through the shut-off port of the decompression and stabilization device, it flows out from the water outlet. When the pressure exceeds 0.4MPa, the axial force of the water pressure flowing out of the outlet on the end face of the movable orifice plate moves it to the inside of the fire hydrant, and the spring is compressed until the water pressure decreases to produce a decompression and pressure stabilizing effect.



How to use Fire Hydrant: 

This product is installed in a fire hydrant box in an obvious position of the building, and is used in conjunction with fire hoses and water guns. In case of fire, quickly connect the fire hose to the fire hydrant, connect the fire hose to the other end, and then turn the fire hydrant handwheel counterclockwise to fire out the water. Widely used in shopping malls, small big school, government agency, house and other places.


Guangbo Brand SN65 Indoor Fire Hydrant are testing by Chinese TESTING CNAS (Chinese National Quality Supervision and Inspection Center for Fixed Fire Extinguishing Systems and Refractory Components.

HOW TO MAINTAIN THE FIRE HYDRANT:

1. Regularly check whether the SNW65 fire hydrant is in good condition and has it rust? If rust, couldn't Rotate when need to extinguish the fire;
2, check if the interface gasket is intact.
3. Lubricant should be added to the SNW65 fire hydrant valve.
4. Perform regular water discharge inspections to ensure that the water can be opened in time when a fire occurs.
5. After the fire is extinguished, wash the hose and dry it, and put it in the box in a coiled or folded manner. After the water gun is stuck in the gun clamp, close the door.
6. Regularly check whether SNW65 fire hydrant, the reel, water gun, and hose are damaged, and whether the valve and reel rotate flexibly. If problems are found, they should be repaired in time.
7. Regularly check whether the SNW65 fire hydrant can be opened, and cabinet door is damaged, whether the door can be opened flexibly, whether the hose frame is intact, and whether the box body is rusty. If problems are found, they must be replaced and repaired in time.
8. In the regular maintenance of the fire hydrant, the drainage operation should also be checked. On the one hand, determine whether the fire hydrant is effectively opened and closed, and whether the water pressure meets the normal scope. On the other hand, SNW65 fire hydrants should be used to drain water on the water distribution network to improve the water quality of the pipe network. In the implementation of SN65 fire hydrant drainage work, in order to ensure the quality of drainage and prevent secondary pollution of the pipe network, hoses should be used to drain the water into the rain well.
