A fire hose is a hose used to transport flame-retardant liquids such as high-pressure water or foam. A traditional fire hose is lined with rubber and wrapped with a linen braid on the outside. Advanced fire hoses are made of polymeric materials such as polyurethane. Both ends of the fire hose have metal connectors that can be connected to another hose to extend the distance or to a nozzle to increase the pressure of the liquid spray.
Fire hoses are divided into two types: lined fire hoses and leaking fire hoses. Lined fire hoses include rubber fire hoses, TPU fire hoses, polyester glue-filled hoses, hemp plastic-coated hoses. According to the working pressure, it is divided into four categories: 0.8MPa, 1.0MPa, 1.3MPa and 1.6MPa. According to the diameter, it is divided into four categories: 50, 65, 80 or 75, 90 mm. According to the weaving method, it is divided into two types: plain weave hose and twill weave hose. The length of each water-saving belt is generally specified as 20 meters.
Fire hose accessories include hose wrap, hose hook, hose bridge, interface, water distributor, etc.
①The hose wrap is used to wrap the leak of the fire hose, and it is one of the necessary accessories on the fire truck. Consists of parts such as canvas straps and metal clamps.
②The hose hook is a tool for hanging the fire hose. In the fire fighting, when laying the hose vertically to a high place, the hose hook hangs the hose on the ladder or other objects, which can not only reduce the falling force of the hose, but also It is convenient for the water gunner to manipulate the water gun to shoot water to put out the fire. The hose hook is composed of a canvas belt, a metal hook and a half ring.
③Hose guard bridge is used to protect the equipment that does not affect the normal driving of vehicles when the water belt is laid across the main traffic road. It has the characteristics of high strength, durable compression and easy cleaning.
④ There are many types of interfaces, including hose interfaces, pipe tooth interfaces, different diameter interfaces, special-shaped interfaces, threaded interfaces, etc. It is used for the connection of hoses and hoses, fire hydrants, fire pumps, water guns and other spraying devices. According to the structural form, it can be divided into inner buckle type, plug-in type and threaded type.
⑤ The purpose of the water divider is to separate two or more streams of water from one flow; the other is to use it as a switch. With the help of the water divider, the water flow can be turned on or off from the water belt line without going to the water pump. Switching is performed, thereby shortening the time required for opening and closing the water flow, and ensuring the water supply to the fire site in time. There are three kinds of water separators: two water separators, three water separators and four water separators.
