Detailed Description
The fire detection and fire extinguishing system suitable for the urban rail maintenance vehicle is further described below with reference to the accompanying drawings.
The fire detection and fire extinguishing system suitable for the urban rail maintenance vehicle comprises a gas storage tank 1 (preferably nitrogen) and a water tank 2 which are filled with water-insoluble gas, wherein the gas storage tank 1 and the water tank 2 are fixed at the bottom of a carriage through mounting seats and bolts, the mounting seats are welded at the bottom of the carriage, an electric valve 3 is respectively arranged at a gas outlet of the gas storage tank 1 and a water outlet of the water tank 2, the electric valve 3 is connected to a gas-water mixing device 4 through a pipeline, the gas-water mixing device 4 can mix the gas in the gas storage tank 1 with the water in the water tank 2 and further atomize the water, the gas-water mixing device 4 is connected with a spray head with the gas-water mixing device 4 through a pipeline, the gas-water mixing device 4 adopts a gas-water mixing valve, a detection device 6 with an alarm function is arranged between the gas-water mixing device 4 and, the flow direction of the water way in the management can be controlled.
In order to improve the reliability of the whole system, all pipelines are made of stainless seamless steel pipes, and the steel pipes are connected by press-fitting clamping sleeve nuts. In northern areas, the system is cold in winter, the freezing of the system in winter is prevented, an automatic heating device is arranged inside the water tank 2, and a heat-insulating material is arranged outside the water tank. In order to make the gas to atomize the water better, the gas container 1 is filled with insoluble gas. The gas storage tank 1 and the water tank 2 can be one-to-one or many-to-one, that is, one gas storage tank 1 and the water tank 2 are used in cooperation in the system, or a plurality of gas storage tanks 1 and one water tank 2 are used in the system correspondingly.
