Embodiment Construction

[0017] Figure 1 to Figure 5 It is a specific embodiment of the present invention.

[0018] The specific implementation and application of the four-stage gas filling includes a high-pressure gas cylinder 1, a safety relief device 2, an air inlet and outlet pipeline 3, a frame 4, a sewage discharge device 5, and a bracket 6. The safety release device 2 can safely protect the high-pressure gas cylinder 1. When the pressure of the high-pressure gas cylinder 1 is greater than the set pressure, it will automatically explode to automatically protect the high-pressure gas cylinder 1. The sewage discharge device 5 can regularly discharge the high-pressure gas cylinder The residual liquid in 1 can effectively prevent the stress corrosion of hydrogen sulfide in the residual liquid inside the high-pressure gas cylinder, and can also play a role in protecting the high-pressure gas cylinder 1.

[0019] The specific structure of the air inlet and outlet pipeline 3 is as follows: image 3 ,...

Abstract

The invention relates to a high-pressure natural gas long pipe trailer for four-stage gas filling, belonging to the technical field of natural gas long pipe trailers. A set of gas inlet and outlet pipeline of a common long pipe trailer is divided into four sets of gas inlet and outlet pipelines. Each set of gas inlet and outlet pipeline comprises I-type serpentine pipes, bends, a three-way joint,thermometers, pressure gauges, a pressure gauge cutoff valve, II-type serpentine pipes, a four-way joint, a high-pressure five-way joint, nozzles, nuts, joints, NPT1 ball valves, double nipples, conical seal welding joints, an elbow, an NPT1 double nipple, an NPT1 gas inlet and outlet ball valve, a gas exhaust cutoff valve, a gas exhaust joint and a quick joint. A No.1 high-pressure gas cylinder and a No.2 high-pressure gas cylinder belong to a medium-pressure group, a No.3 high-pressure gas cylinder and a No.4 high-pressure gas cylinder belong to a low-pressure group, a No.5 high-pressure gas cylinder and a No.6 high-pressure gas cylinder belong to a medium-to-low-pressure group, and a No.7 high-pressure gas cylinder and a No.8 high-pressure gas cylinder belong to a high-pressure group. The NPT1 ball valves are installed among the groups. The high-pressure natural gas long pipe trailer for four-stage gas filling has the advantages that the functions of natural gas storage, transportation and filling are successfully integrated into one body, and the function of filling gas to the outside under no power is realized.

Description

technical field [0001] The invention belongs to the technical field of natural gas long-tube trailers, and in particular provides a four-stage high-pressure natural gas long-tube trailer for gas filling. Background technique [0002] At present, there are only two types of high-pressure gas long-tube trailers in my country: ordinary long-tube trailers and hydraulic long-tube trailers. Ordinary long-tube trailers are used for natural gas transportation between the natural gas filling station and sub-stations, and hydraulic long-tube trailers are used for filling natural gas to the outside world in the gas filling station. Both are relatively specific in use, and the cost of hydraulic vehicles is relatively high, and they must be used in conjunction with hydraulic stations, so the application fields are limited. The successful development of the four-stage gas-filling long-tube trailer overcomes the application limitations of the above two, integrates storage, transportation,...
