Gas dispenser for liquefied natural gas filling station

Abstract

The invention discloses a gas dispenser for a liquefied natural gas filling station. The gas dispenser comprises a base, a case, a pipeline automatic recovery mechanism, a main side plate, an auxiliary side plate, convex blocks, a top cover, a main slide rail, grooves, hinges, gaskets, an auxiliary slide rail, a main transverse frame, an auxiliary transverse frame, acrylic fiber cloth and a handle; and the base and the case are integrally formed, the rear side wall of the case and the front side wall of the pipeline automatic recovery mechanism are fixed through bolts, and the two sides of thetop of the case are fixedly provided with the main side plate and the auxiliary side plate through bolts. According to the gas dispenser for the liquefied natural gas filling station, through cooperative connection of assemblies, the top of the top cover is provided with the convex blocks to be in riveted to the grooves, disassembling and assembling are facilitated, and the stability is high; inaddition, the acrylic fiber cloth is connected to the auxiliary transverse frame, the two ends of the auxiliary transverse frame are sleeved with rollers and embedded into the main slide rail and theauxiliary slide rail, quick pulling can be conducted according to the use requirements, thus, the gas dispenser can be shielded, and display screen reflection is avoided; and the structure is simple,and implementation is easy.

Description

technical field [0001] The invention relates to the technical field of filling machines, in particular to a filling machine for liquefied natural gas filling stations. Background technique [0002] Gas filling machine refers to the gas filling equipment that provides fuel to natural gas vehicles (NGV) and large CNG sub-station cars in the form of compressed natural gas (CNG). The gas in the natural gas pipeline is usually pre-purified to remove the Sulfur and moisture, and then the pressure is compressed from 0.1-1.0Mpa to 25Mpa by the compressor unit, and finally the vehicle is filled with gas through the gas vending machine. [0003] The patent document with the authorization number CN206352755U discloses an LNG dispenser, which includes a device main body, an automatic pipeline recovery mechanism and a combustion-supporting gas extraction mechanism. The device main body includes a top cover, a man-machine interface, a base, and an arc-shaped elastic steel sheet, casing a...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a gas dispenser for liquefied natural gas filling stations, to solve the lack of an effective protection method for the top cover of the gas dispenser proposed in the above-mentioned background technology. The reflective surface of the display screen and the old condition caused by it should be dealt with, and the fixedly installed protective device is not easy to disassemble and assemble. In terms of the protection of different types and widths of gas dispensers, the flexibility is poor and it is not easy to promote.
