lng car gas cylinder

Abstract

The invention discloses an LNG vehicle-mounted cylinder and relates to improvement of an LNG cylinder. The LNG vehicle-mounted cylinder comprises an LNG vehicle-mounted cylinder inner container, a pressurizing liquid outlet pipeline, a carburetor, a filling and gas return integrated device and a gas cylinder protective cover, wherein the pressurizing liquid outlet pipeline is arranged on the LNG vehicle-mounted cylinder inner container; the carburetor is connected with the pressurizing liquid outlet pipeline; the filling and gas return integrated device is connected with the LNG vehicle-mounted cylinder inner container; and the gas cylinder protective cover is arranged on the LNG vehicle-mounted cylinder. The LNG vehicle-mounted cylinder is changed integrally and greatly, the over-charging problem and the potential safety hazard are solved, and waste of the LNG is avoided. The space is greatly reduced, the gas cylinder is safer, and the conversion efficiency is improved when liquid fuel is converted into liquid. The LNG is not liable to flow back to the gas cylinder after being gasified in the process of passing through an inner check valve and arriving at an overflow valve. The gas cylinder protective cover is arranged on a shell seal head of the gas cylinder in a detachable mode, so that the protective cover is easy to change when being deformed. . The LNG is not liable to flow back to the gas cylinder after being gasified in the process of passing through the inner check valve and arriving at the overflow valve.

Description

technical field [0001] The invention relates to an improvement of an LNG gas cylinder, in particular to a novel LNG vehicle-mounted gas cylinder. Background technique [0002] At present, domestic manufacturers still have insufficient research on LNG vehicle-mounted gas cylinders, and even have insufficient understanding of the defects of LNG vehicle-mounted gas cylinders. On the basis of understanding, analyzing, summarizing and researching the existing known technologies and the current situation, the company found that the rapid filling of LNG vehicle-mounted gas cylinders in the process of natural gas filling with LNG has overcharging and safety hazards, resulting in waste of LNG. On the LNG vehicle-mounted gas cylinder, the vaporizer is connected with the buffer tank. Most of the vaporizers are snake-tube vaporizers, which greatly occupies the space, makes the gas cylinder unsafe, and also causes part of the fuel to be lost. When the liquid fuel is converted into liquid...
