Fire hydrant box installation specification hydrant type
The fire hydrant box is a fixed fire-fighting device that is installed on fire-fighting water supply pipelines in buildings and consists of all or part of fire-fighting equipment such as cabinets, indoor fire hydrants, fire fighting interfaces, water hoses, water guns, fire hose reels, and electrical equipment. Has all or part of the functions of water supply, fire extinguishing, control, and alarm. Next Xiaobian introduced the fire hydrant box installation specifications and fire hydrant types.
Fire hydrant box installation specification
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.
The fire hydrant branch shall be positioned with the coordinates of the bolt valve, positioned at the height of the fling, verified and then stabilized the fire hydrant box. After the box is found to be stable, the bolt valve shall be installed. When the bolt valve is installed in the box, it shall be on the side where the door is opened. The box door should be flexible after opening.
The hydrant pipe was hydrostatically tested according to the designated pressure after installation. 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, pressure test pressure is 0.4MPa for working pressure, and it is regulated for 30 minutes. No leakage is acceptable. In order to cooperate with the decoration, the pressure test can be carried out in sections.
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.
Cabinet fittings should be installed before handing over. The fire hoses should be folded and placed on the rack. The coils should be tightly placed inside the box. The fire hoses should be placed on the inside of the box. The self-rescue guns and hoses should be placed on the hanging cards or placed 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.
Fire hydrant type
1, indoor fire hydrant
Indoor fire hydrants are indoor pipe networks supplying water to fire sites, with interfaces for valves, fixed fire-fighting facilities for factories, warehouses, high-rise buildings, public buildings, and ships, usually installed in fire hydrant boxes, and fire hoses and guns. Supporting the use of. Decompression type fire hydrants are one of them.
2, outdoor fire hydrant
The outdoor fire hydrants are water supply facilities installed on the fire-fighting water supply pipe network outside the building, mainly for the fire-fighting vehicles to take water from the municipal water supply pipe network or the outdoor fire-fighting water supply pipe network to extinguish the fire, and can also directly connect the water hose and the water gun to extinguish the fire. Therefore, the outdoor fire hydrant system is also one of the important firefighting facilities for fighting fires.
3, rotating fire hydrant
The rotating fire hydrant is an indoor fire hydrant in which the plug body can rotate 360° horizontally relative to the base connected to the water inlet pipe. It has the characteristics of relative rotation of the plug body and the base, so it can be installed in the ultra-thin case, making it possible to thin the case. When the fire hydrant is not in use, the outlet of the plug body can be rotated to a state parallel to the wall, and the box door can be closed; in use, the outlet of the plug body can be rotated out of the wall body to be connected with the water belt, which is convenient operating.
4, underground fire hydrant
Underground fire hydrant is an outdoor ground fire water supply facility. It is used for fire-fighting vehicles or directly connected with hoses and water guns for fire extinguishing. It is a special facility for outdoor fire-fighting water supply. Installed underground, it does not affect the appearance of the city and the city. It consists of body, elbow, valve seat, valve disc, drain valve, stem and interface. Underground fire hydrants are essential fire-fighting and water supply devices in cities, factories, mines, power stations, warehouses, docks, houses and public places. Especially in urban areas and areas where there are few rivers, they need to be installed. Product structure, reliable performance, easy to use.
5, on the ground fire hydrant
The ground fire hydrant is an outdoor ground fire water supply facility. It is used for fire-fighting vehicles or directly connected with hoses and water guns for fire extinguishing. It is a special facility for outdoor fire-fighting water supply. The upper part is exposed on the ground, the sign is obvious, and it is easy to use. It consists of body, elbow, valve seat, valve disc, drain valve, stem and interface. The fire hydrant on the ground is an urban essential fire-fighting equipment, especially in areas where there are few urban areas and rivers, and it needs to be installed to ensure the need for fireflood. All densely populated areas such as factories, mines, warehouses, yards, freight yards, high-rise buildings, and public places should be installed with conditions.
6, double valve double exit fire hydrant
An indoor fire hydrant is a valved interface that is installed in a building's fire pipe network to provide water to the fire site. It is an indoor fixed fire-fighting equipment such as factories, warehouses, high-rise buildings, and ships. It is used to fight fires in buildings. It is usually installed in fire hydrant boxes and used with fire hoses and water guns.
Editor's summary: The fire hydrant box installation specifications and fire hydrant types are introduced here, and we hope to help everyone. If you want to know more related information, you can pay attention to this website information.
