室外消火栓是设置在建筑物室外消防给水管网上或市政给水管网上的供水设施，是扑救火灾的重要消防设施之一。为了更好的使用它，我们需要对其多了解些内容，下面川消小编来讲讲部分室外消火栓类型。

Outdoor fire hydrant is a water supply facility set on the outdoor fire water supply network or municipal water supply network of buildings, and it is one of the important fire fighting facilities. In order to use it better, we need to know more about it. Now let's talk about some types of outdoor fire hydrants.

1、地上式消火栓

1. Ground type fire hydrant

地上式消火栓与供水管路连接，是一种由阀、出水口和栓体等组成，且阀、出水口以及部分壳体露出地面的消防供水（或泡沫混合液）装置。

The aboveground fire hydrant is connected with the water supply pipeline, which is a fire water supply (or foam mixture) device composed of a valve, a water outlet and a hydrant body, and the valve, the water outlet and part of the shell are exposed to the ground.

地上式消火栓有两个消防水带接口和一个消防车接口。

The ground type fire hydrant has two fire hose interfaces and one fire truck interface.

进水口DN100的地上式消火栓，有两个消防水带接口（DN65）和一个消防车接口（DN100）。

The ground hydrant with DN100 water inlet has two fire hose interfaces (DN65) and one fire truck interface (DN100).

进水口DN150的地上式消火栓，有两个消防水带接口（通常为：DN65和DN80各一个）和一个消防车接口（DN150）。

The ground hydrant with DN150 water inlet has two fire hose interfaces (usually one for DN65 and one for DN80) and one fire truck interface (DN150).

2、地下式消火栓

2. Underground fire hydrant

地下消火栓与供水管路连接，是一种由阀、出水口和栓体等组成，且安装在地下的消防供水（或泡沫混合液）装置。

The underground fire hydrant is connected with the water supply pipeline, which is a fire water supply (or foam mixture) device composed of a valve, a water outlet and a hydrant body and installed underground.

地下式消火栓有一个消防水带接口和一个消防车接口。

The underground fire hydrant has a fire hose interface and a fire truck interface.

进水口DN100的地下式消火栓，有1个消防水带接口（DN65）和一个消防车接口（DN100）。

The underground fire hydrant with DN100 water inlet has one fire hose interface (DN65) and one fire truck interface (DN100).

进水口DN150的地下式消火栓，有1个消防水带接口（DN65或DN80）和一个消防车接口（DN150）。

The underground fire hydrant with DN150 water inlet has one fire hose interface (DN65 or DN80) and one fire truck interface (DN150).

注意：有的地下式消火栓只有消防车接口，没有消防水带接口

Note: Some underground fire hydrants only have fire truck interface, but no fire hose interface

3、防撞型地上消火栓

3. Anti collision ground fire hydrant

防撞型地上消火栓是一种受撞击后，只有某一部件断裂而栓体和阀体不损坏，且保证水不泄漏的一种地上消火栓。

The anti-collision ground fire hydrant is a kind of ground fire hydrant that only one component breaks without damage to the hydrant body and valve body, and ensures no water leakage after being hit.

相对于普通型地上式消火栓，防撞型地上消火栓多了一个自动闭阀机构，受撞击后，自动闭阀机构自动关闭，保证水不泄漏。

Compared with ordinary ground fire hydrants, anti-collision ground fire hydrants have an automatic valve closing mechanism. After being impacted, the automatic valve closing mechanism automatically closes to ensure no water leakage.

4、减压稳压型消火栓

4. Pressure reducing and stabilizing fire hydrant

减压稳压型消火栓，是能将规定范围内的进水口压力减某一出水口压力，并使出水口压力自动保持稳定的消火栓。

The pressure reducing and stabilizing fire hydrant is a fire hydrant that can reduce the water inlet pressure within the specified range to a certain water outlet pressure and automatically keep the water outlet pressure stable.

在常高压和临时高压消防给水系统中，可能压力过高，需要使用减压稳压型消火栓，以方便连接水带直接灭火或消防车取水。

In the normal high pressure and temporary high pressure fire water supply system, the pressure may be too high, so it is necessary to use the pressure reducing and stabilizing fire hydrant to connect the water hose to directly extinguish the fire or take water from the fire truck.

5、折叠式消火栓

5. Folding fire hydrant

折叠式消火栓很少使用，是一种平时以折叠或升缩形式安装于地面以下，使用时能移升地面以上的消火栓。有防冰冻和防撞功能。

Folding fire hydrant is rarely used. It is a fire hydrant that is usually installed below the ground in the form of folding or lifting, and can be moved above the ground when used. It has anti freezing and anti-collision functions.
