LNG客车的安全保护装置包括LNG专用装置上的安全阀、截止阀、单向阀、过流阀,气瓶缓冲罐、漏气自动报警装置、静电拖及发动机舱自动灭火装置。LNG是一种易蒸发、易泄漏、易燃、易爆的深冷液体,所以作为车用燃料时,燃料供给系统和整车的安全防护设计必须更加周密,需要加装安全阀、过流阀、静电拖等安全保护装置,以确保其运行安全可靠。对于LNG客车的驾驶员和维修人员来说,必须了解掌握这些装置的结构和工作原理,才能确保车辆安全、高效的运行。
The LNG bus safety protection devices include safety valves, globe valves, check valves, overcurrent valves, cylinder buffer tanks, automatic air leak alarms, electrostatic drag and engine compartment automatic fire extinguishing devices on LNG dedicated devices. LNG is an easily evaporable, leaky, flammable and explosive cryogenic liquid. Therefore, when it is used as vehicle fuel, the safety design of the fuel supply system and the vehicle must be more thorough. The safety valve, over-flow valve , Electrostatic drag and other safety devices to ensure its safe and reliable operation. For LNG bus drivers and maintenance personnel, we must understand the structure and working principle of these devices to ensure the safe and efficient operation of the vehicle.
