( 1 ) The model and specifications of indoor fire hydrants should meet the design requirements. The fire hydrant cabinet must meet the design requirements (its material is wood, iron and aluminum alloy, etc.), and the bolt valve has a single outlet and double outlets. All products should have a manufacturing license and certification of the fire department before they can be used.

( 2 ) The fire hydrant branch pipe should take the coordinates of the bolt valve, locate the swing at the elevation, check and stabilize the fire hydrant box, fix the box and fix the bolt, then install the bolt valve on the side of the box and open the box door. On one side, the door should be flexible after opening.

(3) fire hydrant plug port height from the ground surface layer is suitably 1. 10m, fire hydrant water Fang Xiangyi plug port provided downward or perpendicular wall hydrant. The center of the valve is 1. 2m away from the ground , and the allowable deviation is 20mm ; the valve is 140mm from the side of the box, 100mm from the back surface of the box, and the allowable deviation is 5mm . (The deviation can be written in the quality requirements.) The bottom of the box should be flush with the baseboard.

( 4 ) The indoor fire hydrants should be installed in the walls of the wall and equipped with glass doors for protection. If a fire hydrant box is used, the protruding part of the fire hydrant box should not affect the safety evacuation. The fire hydrant cabinet must meet the design requirements ( its material is wood, iron and aluminum alloy, etc. ) .

( 5 ) The fire hydrant branch pipe shall be positioned with the coordinates and elevation of the bolt valve. The fire hydrant box shall be secured and then fixed. After the cabinet is found to be stable, the bolt valve shall be installed. When the bolt valve is installed in the box, it shall be opened in the box door. On one side, the door should be flexible after opening.

( 6 ) Cabinet fittings should be installed before handing over. The fire hoses should be folded and placed on the pylon, tightly placed in the box ; the fire hose should be placed on the inside of the box, and the self-rescue gun and hose should be placed on the card or on the bottom of the box. Fire hoses and water guns, quick connector connection, generally with 14 # wire tied two, each not less than two laps, when using clamps, add a lead in the inside. When there is an electronically controlled button, attention should be paid to professional construction with electrical appliances.

( 7 ) There should be reinforcement measures for the fire hydrant cabinet installed on the light partition wall.

( 8 ) The button to activate the fire pump shall be located in the fire hydrant box or in the wall of the wall where the fire hydrant is installed.

( 9 ) After the installation of the fire hydrant pipe, the hydraulic pressure test is carried out according to the design pressure. If the design does not require the general working pressure is less than 1.0MPa , the test pressure is 1.4MPa . Working pressure is 1MPa or more, test pressure is working pressure plus 0.4MPa , pressure is 30 minutes, no leakage is qualified. In order to cooperate with the decoration, the pressure test can be carried out in sections.

( 10 ) After the pressure test of the fire hydrant system pipeline, the flushing work can be performed continuously. When the flushing water flow in the pipe meets the design requirements, the water quality at the inlet and outlet can be over.
