PRODUCT OVERVIEW 
SN type indoor fire hydrant is a product designed according to the GB3445-2018 "Indoor Fire Hydrants" standard,with the characteris-tics of rapid opening and closing,reasonable structure,and easy maintenance.Suitable for extinguishing fires on ships in residential areas,factories, government offices, schools, public places,and transportation. Usually installed inside the fire hydrant box and used in conjunc-tion with water hoses,water guns,interfaces,etc.This product is connected to the water supply network,and the outlet is equipped with an interface that can quickly connect to the water hose. When the handwheel is turned counterclockwise,the valve disc opens,and the water flow in the network enters the DC water gun through the connecting water hose to spray fire.This series of fire hydrants comes in various types to meet different installation and usage requirements.

PRODUCT FORM 
The SNZ indoor fire hydrant maintains the appearance,standard interface form,and traditional installation and operation methods of or-dinary indoor fire hydrants. At the same time,the hydrant body can rotate 360 ° relative to the base to achieve the optimal outlet angle,re-duce water resistance,and facilitate use.The SNW indoor fire hydrant maintains the appearance,standard interface form,and traditional installtion and operation methods of ordinary indoor fire hydrants. On this basis,it adds a pressure reduction and stabilization function.Regardless of the inlet pressure,the pres- 
sure in the pipeline network fluctuates and changes,and the outlet pressure can be reduced and stabilized at the operating pressure value.The SNZW indoor fire hydrant maintains the appearance,standard interface form,and traditional installation and operation methods of ordinary indoor fire hydrants. On this basis,it adds a pressure reduction and stabilization function. Regardless of the inlet pressure,if there are fluctuations and changes in the pressure inside the pipeline network,the outlet pressure can be reduced and stabilized at the operating pressure value; At the same time,the plug body can rotate 360° relative to the base,achieving the optimal outlet angle,reducing water resis-tance, and making it easy to use.

PRODUCT MIX 
Indoor fire hydrants are mainly composed of handwheel, valve cover, valve stem, valve body,valve disc,valve seat, fire interface,etc.Rotating indoor fire hydrants are mainly composed of handwheel,valve cover,valve stem,valve body,valve disc,base,rotating kit,fire interface,etc. 
The pressure reducing and stabilizing indoor fire hydrant is mainly composed of a handwheel, valve cover, valve stem,valve body,valve disc,valve seat,fire interface,throttling device,etc.

USAGE METHOD 
Indoor fire hydrants are installed in prominent fire hydrant boxes in buildings and are used in conjunction with water hoses and guns.If there is a fire, quickly connect the water hose to the fire hydrant, connect the other end of the hose to a water gun, unscrew the fire hydrant,and you can use water to extinguish the fire.

INSTALLATION AND MAINTENANCE 
1.Before installation,the valve must be unscrewed to prevent the rubber gasket from sticking to the valve seat and causing damage. 
2.Afterinstallation,thegarbageandimpuritiesinside thepipelineshouldberemoved.whenclosingthevalve,it isnotallowed for the rubber gasket to be stuck with mud,white paint,or other impurities. 
3.After the installation of the fire hydrant, the valve should be opened regularly (usually every two weeks) to prevent rubber from stick-ing to the valve seat and causing damage. 
4. Regularly check whether the rubber pad is aging and damaged. If water leakage is found,it should be replaced in a timely manner.
