LNG vehicle-mounted gas cylinder processing method

Abstract

The invention discloses an LNG vehicle-mounted gas cylinder processing method comprising the steps of winding, reinforcing and sleeving. The specific steps are as follows that the winding step is conducted, and specifically, the outer wall of a gas cylinder liner are wound with glass fiber paper and aluminum foil through a winding machine; the reinforcing step is conducted, and specifically, the outside of thermal insulation material is reinforced and wound with copper wires; and the sleeving step is conducted, specifically, the reinforced liner is sleeved with an outer barrel, and the gap ofthe liner and the outer barrel is vacuumized. According to the LNG vehicle-mounted gas cylinder processing method, the thermal insulation material is reinforced through the copper wires, a protectioneffect is achieved on the thermal insulation material, the heat insulation effect can be controlled, tightness is moderate, the gas discharge speed is small, later vacuumizing operation is also facilitated more, labor is saved, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of gas cylinder equipment, in particular to a method for processing an LNG vehicle-mounted gas cylinder. Background technique [0002] Compressed natural gas cylinders for vehicles are economical, safe and environmentally friendly gas storage equipment for motor vehicles. With the continuous changes in international oil prices, the number of motor vehicles has increased sharply, and people's awareness of environmental protection has gradually increased. It is widely used in fields such as public transportation and automobile transportation. [0003] As a low-temperature heat-insulating pressure vessel, the LNG vehicle-mounted gas cylinder is generally a double-layer vacuum structure. The inner tank is used to store low-temperature liquid liquefied natural gas, and the outer wall is wound with multiple layers of heat-insulating composite layers to make it have super heat insulation performance. At the same time, the j...

Problems solved by technology

The traditional process is to directly wrap a layer of thermal insulation material on the outer wall of the inner tank. During the assembly process of the inner tank and the outer cylinder, the thermal insulation material wrapped on the inner tank is often easily damaged, which seriously affects the thermal insulation performance of the gas cylinder.
