Hydrant can be roughly divided into indoor fire hydrant and outdoor fire hydrant.
(i) Indoor fire hydrants are a type of fixed fire-fighting water supply equipment used inside buildings. It includes fire hydrants and fire boxes. Indoor fire hydrants and fire boxes are usually set up with stairwells, corridors and indoor walls. There are hoses and guns in the box and it is connected to the outlet of the fire hydrant. Fire hydrants are connected to fire water supply pipes in buildings. The fire hydrant consists of a hand wheel, a valve cover, a valve stem, a body, a valve seat, and an interface. In use, according to the opening method of the fire hydrant door, use the key to open the door or break the door glass, twist the lock open. If there is no “emergency button†on the fire hydrant, the pull ring under it should be pulled out, then turn the knob clockwise, open the door, open the door, remove the water gun, press the pump start button, rotate the fire hydrant Wheels, that is, fire hydrants are turned on, and hoses are laid to fire water.
Care and maintenance of indoor fire hydrants should pay attention to:
1. Regularly check whether the fire hydrants are in good condition and whether there is any rust or water leakage.
2, check the interface gasket is intact.
3. Hydrant valve stem should be filled with lubricating oil.
4. Regularly check the water discharge to ensure that the water can be opened in time when a fire occurs.
5. After the fire is extinguished, the hose must be washed and dried and placed in the box by coiling or folding.
After the water gun is stuck in the holster, the box lock is installed, the glass is changed, and the door is closed.
6, to regularly check the reel, water gun, water hose is damaged, the valve, reel rotation is flexible, found that problems should be promptly repaired.
7. Check whether the door of the fire hydrant box is damaged regularly, whether the door lock is opened flexibly, whether the seal of the pull ring is damaged, whether the water transfer plate is in good condition and whether the box body is rusted. Find problems that need to be replaced and repaired in a timely manner.
(b) Outdoor fire hydrants are connected to the urban water supply network. It can be used for water extraction from fire trucks. It can be connected directly to water and water guns to extinguish the fire. The outdoor fire hydrant has two types of fire hydrant on the ground and underground fire hydrant. The fire hydrant on the ground is used in areas with warmer climates, while the underground fire hydrant is suitable for areas with cold weather.
1. Above-ground fire hydrant Ground fire hydrant is mainly composed of curved seat, valve seat, drain valve, flange take-up and closing lever, body and interface. When using the fire hydrant on the ground, after the hydrant key is used to move the hydrant key in the counterclockwise direction after the head is pivoted by the fire hydrant key, the valve can be opened and the water flows out from the outlet. When you turn the hydrant key clockwise, the valve closes and water does not flow out of the outlet.
Daily, to deal with the maintenance and repair of fire hydrant on the ground:
(1) A fire hydrant should be checked before each month and major holidays.
(2) Remove debris around the opening and closing bar.
(3) Put a special fire hydrant key on the club head to check if it is suitable, and turn the opening and closing lever to add lubricant.
(4) Wipe off the rust on the outlet thread with gauze and check if the rubber gasket in the door cover is intact.
(5) Open the fire hydrants and check the water supply. Put clean rust on the water and then close it. Observe whether there is any water leakage and if any problems are discovered and repaired in time.
2. Underground fire hydrants Underground fire hydrants have the same function as above-ground fire hydrants. They provide pressurized water for fire engines and water guns. The difference is that the underground fire hydrants are installed under the ground. Because of this, underground fire hydrants are not easily frozen and are not easily damaged. The use of underground fire hydrants can be carried out with reference to fire hydrant on the ground. However, because the target of the underground fire hydrant is not obvious, a clear sign should be set up near the underground fire hydrant. When used, open the fire hydrant cover, unscrew the cover, connect the hydrant and suction pipe connection or take the water, use a special wrench to open the valve plug to water, after use to restore the original state.
