室外消火栓是指設置在建筑物外消防給水管網的一種供水設備。它的作用是向消防車提供消防用水或直接接出水帶、水槍進行滅火，按設置條件分為地上式消火栓和地下式消火栓；按壓力分為低壓消火栓和高壓消火栓。
Outdoor fire hydrant refers to a kind of water supply equipment set in the fire water supply network outside the building. Its function is to provide fire water for fire engines or directly connect water hoses and water guns to put out fire. According to the setting conditions, it is divided into aboveground fire hydrants and underground fire hydrants; It is divided into low-pressure fire hydrant and high-pressure fire hydrant according to pressure.
1、地上消火栓
1. Aboveground fire hydrant
地上式消火栓大部分露出地面，具有明顯、易于尋找、出水操作方便等優點，適用于冬季氣溫較高的地區。但地上消火栓容易凍結、易損壞，在有些場合還妨礙交通。地上式消火栓由本體、進水彎管、閥塞、出水口和排水口等組成。
Most of the above ground fire hydrants are exposed to the ground, which has the advantages of obvious, easy to find, convenient water outlet operation and so on. It is suitable for areas with high temperature in winter. However, the fire hydrant on the ground is easy to freeze and damage, and it also hinders traffic on some occasions. The above ground fire hydrant is composed of a body, a water inlet elbow, a valve plug, a water outlet and a water outlet.
2、地下式消火栓
2. Underground fire hydrant
地下式消火栓設置在消火栓井內，具有不易凍結、不易損壞、便利交通等優點。適用于北方寒冷地區使用。但地下消火栓操作不便，目標不明顯，特別是在下雨天、下雪天和夜間。因此，要求使用單位在地下式消火栓周圍應設明顯的標志。地下式消火栓由彎頭、排水口、閥塞、絲桿、絲桿螺母、出水口等組成。
The underground fire hydrant is set in the fire hydrant shaft, which has the advantages of not easy to freeze, not easy to damage, convenient transportation and so on. It is suitable for use in northern cold areas. However, the underground fire hydrant is inconvenient to operate and the target is not obvious, especially in rainy days, snowy days and night. Therefore, the user is required to set up obvious signs around the underground fire hydrant. Underground fire hydrant is composed of elbow, drain, valve plug, screw rod, screw rod nut, water outlet, etc.
3、低壓消火栓
3. Low pressure fire hydrant
室外低壓消防給水系統管網上設置的消火栓，稱為低壓消火栓。低壓消火栓不能直接向火場供水，而是將水放進消防車的水罐內（或消防車利用吸水管與消火栓相接）、通過消防車上的加壓泵送水滅火。
The fire hydrant set on the pipe network of outdoor low-pressure fire water supply system is called low-pressure fire hydrant. The low-pressure fire hydrant cannot directly supply water to the fire site, but put water into the water tank of the fire truck (or the fire truck connects with the fire hydrant through the suction pipe) and send water to extinguish the fire through the pressurized pump on the fire truck.
4、高壓消火栓
4. High pressure fire hydrant
室外高壓或臨時高壓消防給水系統管網上設置的消火栓。
Fire hydrants set on the pipe network of outdoor high-pressure or temporary high-pressure fire water supply system.
The classification of outdoor fire hydrants according to setting conditions and pressure is the above explanation. If you want to consult about this, you can come to the website at any time http://www.xintli.net have a look.
