Multifunctional combined integrated cabinet

The invention discloses a multifunctional combined integrated cabinet. A vaporizer and a buffer tank are arranged on the lower portion of a fixed frame. An electromagnetic valve, a pressure stabilizing valve and a filter are arranged at the top of the fixed frame. A pressure regulating valve is arranged on the vaporizer. A liquid filling panel is connected to the fixed frame. A liquid inlet connector is connected with the vaporizer. One end of a connecting pipe is connected with the vaporizer, and the other end of the connecting pipe is connected with the pressure regulating valve. One end of a gas inlet pipe of the buffer tank is connected with the pressure regulating valve, and the other end of the gas inlet pipe of the buffer tank is connected with the buffer tank. One end of a gas outlet connector is connected with a gas outlet of the buffer tank, and the other end of the gas outlet connector is connected with a gas inlet of the electromagnetic valve. The gas outlet of the electromagnetic valve is connected with the filter. The gas outlet of the filter is connected with the pressure stabilizing valve. According to the multifunctional combined integrated cabinet, by adopting the way of combination integrating, the multiple functions of liquid filling, gas returning, vaporizing, pressure regulating, buffering, electromagnetic control, fuel gas filtering, pressure stabilizing, pressure displaying and the like of a gas cylinder for a liquefied natural gas (LNG) vehicle are integrated.
