Abstract

This invention relates to liquefied natural gas automobile tube over casting resistant device in the liquefied natural gas application technique field. The device comprises LHG storage tar, low temperature pump, vacuum isolation heating tube, rapid connector, fuel gas tube, gas saving valve and spray device. This invention uses the spray device fixed on the fuel gas tube to make the LNG sprayed out by smoke to realize the condensing by vapor and voltage reducing and LNG adding to ensure the fuel gas tube maintained with enough expansion space to prevent over adding.

Description

technical field [0001] The invention relates to a liquefied natural gas (LNG) fuel filling device, in particular to a fuel gas bottle anti-overfilling device for a LNG vehicle filled with a sprayer, and belongs to the technical field of liquefied natural gas applications. Background technique [0002] LNG is a high-quality clean fuel used in buses and heavy trucks, which can effectively improve the air pollution caused by vehicle exhaust. During the Tenth Five-Year Plan period, the National Science and Technology Commission launched the "Clean Vehicle Action Plan", which listed urban LNG public transport as a research and demonstration project, aiming to promote the progress of LNG vehicle technology. [0003] With the increasing proportion of LNG in the energy field, the application prospect of LNG vehicles is very broad. As a low-temperature liquefied gas, LNG naturally increases the pressure of the fuel cylinder under the influence of ambient temperature. As we all know...
