That is, in the position facing the door of fire hydrant box box, the door shaft is on the left, the door opening to the left is the left, the door opening to the right, and the door shaft to the right is the right.
The fire box is a box for storing fire hydrants. In case of fire, press the spring lock on the door according to the opening mode of the box door, and the bolt will automatically withdraw. After opening the door, remove the water gun and pull the hose. At the same time, connect the hose interface with the hydrant interface, pull the power switch on the wall in the box, unscrew the handwheel of the indoor hydrant in the opening direction, and spray water to extinguish the fire.

Methods of reading fire protection drawings
Reading order of drawings: general plan (distinguishing buildings)-design description and drawing legend-system diagram-fire plan.
1, fire engineering drawings are generally divided into drainage (automatic sprinkler, fire hydrant and gas fire extinguishing), electrical (automatic fire alarm) and smoke control.
2. According to the professional classification, the specific equipment installation costs can be found in the fire protection installation quota, such as nozzles, spray pipes, supports and hangers, fire hydrants, alarm valves, probes, modules, alarm equipment, etc. Other general parts have corresponding professional quotas, such as fire hydrant pipeline water supply and drainage pipeline quota, pump room industrial pipeline quota, fire pump mechanical equipment quota, valve flange industrial pipeline quota, alarm part pipeline installation quota, etc.
3. Material algorithm: the number of equipment can be based on the number of drawings, and the pipes and conduits need to be improved by themselves.
