Problems solved by technology

[0003] In the process of filling the steel cylinder with petroleum gas, first unscrew the valve of the steel cylinder, at this time the inside of the steel cylinder is connected with the outside air, causing the air to enter, and then connect the filling head to the cylinder interface, the air at the cylinder interface will also be released Squeeze into the inside of the cylinder, resulting in residual air in the cylinder, which will increase the oxygen content in the internal gas phase space, and there is a risk of explosion

Abstract

The invention discloses a novel liquefied petroleum gas storage, distribution and filling structure which comprises a filling head, the front end of the filling head is communicated with a gas filling pipe, the outer side of the gas filling pipe is rotatably connected with an outer threaded pipe matched with a steel cylinder connector in a sealed mode, and the front end of the gas filling pipe is movably connected with an inner gas filling block. An air inflation channel is formed in the inner air inflation block, an air guide auxiliary mechanism is arranged at an air outlet of the air inflation channel, a mounting notch is formed in the upper end of the inner air inflation block, an air exhaust auxiliary mechanism and the air guide auxiliary mechanism are arranged in the mounting notch, and petroleum gas is guided to flow to the bottom of the steel cylinder through the air inflation channel. And air at the bottom of the steel cylinder flows upwards. According to the technical field of liquefied petroleum gas inflation, the liquefied petroleum gas storing, distributing and filling structure can effectively conduct directional flow guiding and deoxidizing operation on air in a steel cylinder in the inflation process, and the hidden danger of explosion is effectively eliminated.

Description

technical field [0001] The invention relates to the technical field of liquefied petroleum gas inflation, in particular to a novel liquefied petroleum gas storage, distribution and filling structure. Background technique [0002] The main functions of the LPG storage and distribution station include LPG storage, truck loading and unloading, cylinder filling, cylinder residual liquid recovery, LPG backfilling, etc. Before filling new cylinders or overhauled cylinders, It is necessary to extract the air in the cylinder to ensure safety, and the oxygen content of the gas phase space in the cylinder needs to be controlled below 4%. [0003] In the process of filling the cylinder with petroleum gas, first unscrew the valve of the cylinder. At this time, the interior of the cylinder is connected to the outside air, causing the air to enter. Then the filling head is connected to the cylinder interface, and the air at the cylinder interface will also be released. Squeeze into the i...
