Description

Technical Field

[0001] This utility model relates to the field of natural gas refueling stations, specifically to a refueling nozzle suspension device for liquefied natural gas refueling stations. Background Technology

[0002] A gas station is a place that provides fuel to natural gas vehicles and CNG / LNG trailers in the form of compressed natural gas or liquefied natural gas. Natural gas has become the main household fuel in my country, so natural gas refueling stations are set up in many places.

[0003] A Chinese patent discloses a coal drum magnetic separator (authorization announcement number CN 209753111 U). This patented technology "automatically sounds an alarm in the presence of dense smoke and high temperatures by setting up smoke and temperature detectors, making it easy for staff to be aware. An alarm button allows staff to trigger a starter, and a controller allows the opening of the compression tank's valve, enabling liquid carbon dioxide to enter the pipe and be automatically sprayed out from the nozzle, thus extinguishing any fire that may occur in a natural gas dispenser." This addresses the problem that "many natural gas refueling stations are still manually controlled, which inevitably leads to errors. When there is excessive pressure in the storage tank or a natural gas leak, it is difficult to detect in time, easily leading to accidents." However, this patent still has the following problems:

[0004] The gas dispenser in this patent uses a single fixing method for its gas gun, which results in poor fixing effect. Furthermore, the gas gun has an open structure when placed, and the gas outlet of the gas gun is prone to dust accumulation, leading to poor performance. Utility Model Content
