Compressed liquefied gas charging system

Abstract

The invention relates to a compressed liquefied gas charging system, belonging to the liquefied gas charging field. The compressed liquefied gas charging system comprises a liquid storage tank, a charging pump, a gas bottle and a charging platform, wherein the charging pump is connected with the liquid storage tank by a pipeline; the gas bottle is arranged on the charging platform and is connected with the charging pump by the pipeline; the charging pump is connected with an automatic flow rate adjusting device used for automatically controlling the flow rate of the charging pump; an intelligent quantifying charging device used for automatically controlling the charging quantity is arranged between the gas bottle and the charging pump; the compressed liquefied gas charging system also comprises an adjusting control center device and an automatic pressure adjusting device; the automatic flow rate adjusting device and the intelligent quantifying charging device are also respectively connected with the adjusting control center device by a control circuit; and one end of the automatic pressure adjusting device is connected with the adjusting control center device, and the other end thereof is connected with the liquid storage tank. By adopting the structure, the compressed liquefied gas charging system has the advantages of full-automatic control, accurate charging quantity, low cost, safety, long service life and the like.

Description

【Technical field】 [0001] The invention relates to the technical field of filling liquefied gas, in particular to the technical field of filling compressed liquefied gas. 【Background technique】 [0002] Liquefied petroleum gas has a high calorific value, takes up little space for storage, and is easy to use, so it is very popular among the people. However, liquefied gas is flammable, explosive, and volatile, and its storage and transportation are greatly restricted. Usually, a large liquefied gas tank is installed at a liquefied gas station, and the large liquefied gas tank is filled with liquefied gas through a liquefied gas filling device. Fill into the user's liquefied gas cylinder. At present, there are two kinds of liquefied gas filling devices commonly used in the industry, namely: mechanical quantitative filling device and electronic scale quantitative filling device. The mechanical quantitative filling device is a simple mechanical device that closes the valve of th...

Problems solved by technology

The mechanical quantitative filling device is a simple mechanical device that closes the valve of the gas valve switch only by touching the gas valve switch when the beam beam is lifted. Its function is too simple to get rid of the backward working mode of the mechanical scale. The weighing process is cumbersome, the exposed knife edge is easy to be damp, rusted or corroded, which will affect the accuracy of the weighing, and it needs professional maintenance and inspection before it can continue to be used.

Although the electronic scale quantitative filling device can achieve the purpose of convenient weighing and simple operation, it also has the following disadvantages: 1. It cannot distinguish and eliminate the disturbing force that is easily generated during the filling process, such as the leakage of the fixture joint The force generated by clapping the chuck will lead to early closure caused by the virtual weighing fixed value; 2. It only has the function control of quantitative filling of a single gas cylinder
