Anti freezing and anti-collision outdoor fire hydrant

Description :

　　Outdoor fire hydrants are water supply facilities installed on the fire water supply network outside buildings, mainly used for fire trucks to draw water from the municipal water supply network or outdoor fire water supply network to extinguish fires. They can also be directly connected to water hoses or water guns to extinguish fires.

　　Therefore, outdoor fire hydrant systems are also one of the important fire-fighting facilities for extinguishing fires.

　　1. The selection of underground and above ground fire hydrants should be tailored to local conditions. In some cities, the planning and installation of fire hydrants in the municipal water supply network emphasizes the use of underground type, while in other cities, the original underground type has been completely transformed into ground type. Underground fire hydrants have the advantages of strong concealment, no impact on urban aesthetics, minimal damage, and anti freezing in cold areas. However, as a user and management department, it is not very convenient to find and maintain, and it is easy to be buried, occupied, and compressed by building vehicles. A large number of underground fire hydrants require well protection, which requires a large amount of capital investment. At the same time, they occupy a considerable position in urban underground pipeline planning, bringing difficulties to the planning. On the other hand, above ground fire hydrants are more conspicuous, easy to find, and convenient to use and maintain, but they are prone to damage and theft of water. If a fire hydrant is truly installed within 120 meters according to the specifications, it will inevitably have a certain impact on the urban streetscape. Fire hydrants are mainly used for extinguishing fires and obtaining water. Therefore, as the department using fire hydrants, it is the desire and requirement of the fire department to quickly find fire hydrants, obtain water quickly, conveniently, and easily. The selection of fire hydrants should be tailored to local conditions, taking into account both the usage and urban landscape, as well as maintenance and management. Therefore, the combination of underground and ground types should be considered. And the specifications and models of fire hydrants should not be too many, making them easy to use and maintain. 2. The outlet diameter of the fire hydrant shall not be less than 100mm. With the increase of urban buildings and population density, the difficulty of extinguishing fires has increased. In order to ensure the water pressure and quantity requirements for extinguishing fires, it is necessary to ensure that at least one outlet diameter of the fire hydrant is not small, with a diameter of not less than 100; mm。

　　3. The opening and closing direction of the fire hydrant should be uniform, both clockwise and counterclockwise. The screw rod should be made of stainless steel, and the sealing cup should be made of EPDM rubber or nitrile rubber. The anti-corrosion inside the cavity should meet the hygiene standards of drinking water and be consistent with the requirements of the valve.
