当建筑物发生火灾时,消防人员首先要尽快打开消火栓盖接好水管供水灭火。因此,消火栓盖和接口必须长期保持性能良好,以便随时待用。当前普遍使用的金属消火栓盖和接口都存在以下难以解决的问题: 1.由于无人维修保养和清洁除垢,因此,消火栓盖和接口总因污垢多等故障难以使用。 2.金属消火栓盖和接口冬天易结冰,潮湿天气又易生锈,或被化学等物品腐蚀,难以使用。 老式消火栓盖和接口存在的上述缺点,往往使消防人员延误灭火战机,造成严重的火灾损失。为了解决此难题,德国消防科技人员经过多方选料和试用,终于
When a fire occurs in a building, firefighters should first open the fire hydrant cover and connect the water pipe to extinguish the fire as soon as possible. Therefore, the fire hydrant cover and interface must maintain long-term good performance, ready for use. Currently, the commonly used metal fire hydrant lids and connectors have the following unresolved problems: 1. The fire hydrant lids and connectors are often difficult to use because of dirt and other faults due to unmanned maintenance and cleaning. 2. Metal fire hydrant cover and interface Easy to freeze in winter, wet weather and easy to rust, or corrosion by chemicals and other items, difficult to use. The above shortcomings of the old fire hydrant cover and interface often make firefighters delay fire fighters, causing serious fire damage. In order to solve this difficult problem, the German fire-fighting scientific and technical personnel have passed the test and selection of various parties finally
