Question:
outdoor fire hydrant, what practical use ah?

Answer:
outdoor fire hydrant As the name suggests is a disaster in the event of fire departments, a device used for fire-fighting water.

1. Select Underground-style fire hydrant fire hydrant and the ground should be adapted to local conditions. In the municipal water supply network in some cities to plan and set fire hydrant water distribution network with emphasis on an underground style, while some cities were all from the original Underground has transformed into the ground type. Underground Fire Hydrant with hidden strong, does not affect the city appearance, subject to damage small areas can be freezing cold and so on. However, as the use and management is concerned, not very convenient for maintenance, easy to park construction vehicles, and so buried, accounting, pressure, a large number of underground wells Room-style fire hydrant needs the protection of big capital investment, while in the urban underground pipe network planning occupy a lot of position, causing difficulties to the plan. The ground-type fire hydrant while the other hand, more eye-catching, easy to find, use and maintenance more convenient, but easily damaged, easily result in theft of water. If the true standard 120 meters by setting a fire hydrant, is bound to cause some impact on urban streets. Fire hydrant water is mainly used for fire extinguishing purposes, so as a fire hydrant in terms of user departments, how to quickly find a fire hydrant, water fast, convenient and easy is the fire department wishes and requirements. It is necessary to satisfy the use, but also to consider the cities King, while also conducive to maintenance and management, and therefore the choice of fire hydrant should be adapted to local conditions, underground-style combination of ground-type. And the fire hydrant specification model not too much, easy to use maintenance.

2. Fire hydrant outlet shall not be less than the diameter φ100mm. With the urban construction and population density increased, fire-fighting more difficult, in order to ensure that the water pressure fire fighting water requirements, must ensure that at least one fire hydrant water is not a small-caliber φ100 mm.

3. The open and close direction of the fire hydrant should be harmonized, should be closed by clockwise counter-clockwise to open. The screw should be stainless steel, sealed cuffs use EPDM rubber or nitrile rubber, the body cavity antisepsis should meet the drinking water, health indicators and so on, the valve should be a uniform requirement.

Chinese:室外消火栓有什么实际用途啊?

问题:
室外消火栓有什么实际用途啊?

回答:
室外消火栓顾名思义就是在出现火情灾害时消防部门用于取水灭火的一种装置。

1.选择地下式消火栓与地上式消火栓应因地制宜。在市政给水管网中有些城市给水管网的消火栓规划设置强调采用地下式,而有些城市则由原来的地下式又全部改造为地面式。地下式消火栓有隐蔽性强,不影响城市美观,受破坏情况少,寒冷地带可防冻等优点。但作为使用和管理部门来讲,寻找维修不甚方便,容易被建筑车辆停放等等埋、占、压,大量的地下式消火栓需要井室保护,资金投入大,同时在城市地下管网规划中占据了不少的位置,给规划带来了困难。而地上式消火栓则反之,比较醒目,容易寻找,使用、维修较方便,但容易受破坏,易造成偷窃用水。若真正按规范120米设置一个消火栓,势必对城市街景造成一定影响。消火栓主要用于灭火取水之用,因此作为消火栓使用部门来讲,如何快速寻找到消火栓,取水快捷、方便、容易是消防部门的愿望和要求。既要满足使用,又要考虑市容市景,同时还要利于维护管理,因而消火栓的选择应因地制宜,地下式地面式相结合。且消火栓的规格型号不要太多,便于使用维护。

  2.消火栓出水口径不得小于φ100mm。随着城市建筑及人口密度加大,灭火的难度增大,为确保灭火的水压水量要求,必须保证消火栓至少一个出水口径不小φ100 mm。

  3.消火栓的启闭方向应统一,均应按顺时针关逆时针开。其丝杆应采用不锈钢,密封皮碗选用三元乙丙橡胶或丁晴橡胶,腔体内防腐应满足饮用水卫生指标等,应与阀门要求一致。
