Embodiment Construction

[0008] In the above drawings, the movable gas cylinder card 1 is composed of two movably connected half rings and a base, the base is fixed on the vehicle body, one connection of the two half rings is a movable shaft connection, and the other connection is a movable buckle, Fix the vehicle CNG bottle 2 on the vehicle body; one end of the bottle mouth valve body joint 3 is a left-hand thread (ie, reverse buckle), which is connected with the bottle mouth valve of the car CNG bottle 2, and the other end is fast-installed with the pipeline. Port 4 is a quick-fit joint that matches the gas filling gun interface of the parent station gas dispenser. In the middle is a ball valve with a pressure relief hole. When the ball valve is closed, the relief hole is connected to the quick-fit joint. When the ball valve is open, the relief hole is connected. is closed; the pipeline quick installation interface 4 is composed of a high pressure hose connected to the quick installation interface, t...

Abstract

The invention relates to a method for exchanging natural gas bottle, which is formed by a movable air bottle clamp, a vehicle compression natural gas bottle, a bottle valve interface, and a pipeline interface. The compressed natural gas bottle is clamped on the vehicle via movable gas bottle; the bottle valve interface is inserted into pipeline interface connecting with the vehicle gas feeding pipe. It can fill gas into vehicle via exchanging the compressed natural gas bottle with bottle valve interface. The invention has less device, lower cost, easy operation, and environment-friendly.

Description

technical field [0001] The present invention relates to a compressed natural gas vehicle refueling method and device. Background technique [0002] Compressed natural gas vehicles have many advantages such as environmental protection and energy saving, and are popularized and used in more and more areas. However, the construction of gas stations is restricted by natural gas pipelines, environmental conditions and other factors, which affect the development of gas vehicles. The method of parent-child gas filling station is to build a gas filling station at a suitable location near the gas transmission pipeline, and build a gas filling sub-station in an area where gas vehicles drive a lot. Although the location of the sub-station can get rid of the restriction of the gas supply pipeline, the sub-station It needs to be equipped with a transport tanker to transport compressed natural gas, and equipment such as a compressor, a large-volume gas storage of several cubic meters, a ...
