室外消火栓是指设置在建筑物外消防给水管网的一种供水设备。它的作用是向消防车提供消防用水或直接接出水带、水枪进行灭火，按设置条件分为地上式消火栓和地下式消火栓；按压力分为低压消火栓和高压消火栓。
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，具有明显、易于寻找、出水操作方便等优点，适用于冬季气温较高的地区。但地上消火栓容易冻结、易损坏，在有些场合还妨碍交通。地上式消火栓由本体、进水弯管、阀塞、出水口和排水口等组成。
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
地下式消火栓设置在消火栓井内，具有不易冻结、不易损坏、便利交通等优点。适用于北方寒冷地区使用。但地下消火栓操作不便，目标不明显，特别是在下雨天、下雪天和夜间。因此，要求使用单位在地下式消火栓周围应设明显的标志。地下式消火栓由弯头、排水口、阀塞、丝杆、丝杆螺母、出水口等组成。
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、低压消火栓
3. Low pressure fire hydrant
室外低压消防给水系统管网上设置的消火栓，称为低压消火栓。低压消火栓不能直接向火场供水，而是将水放进消防车的水罐内（或消防车利用吸水管与消火栓相接）、通过消防车上的加压泵送水灭火。
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、高压消火栓
4. High pressure fire hydrant
室外高压或临时高压消防给水系统管网上设置的消火栓。
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.cx-fire.com have a look.
