Embodiment Construction
[0025] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various changes in different embodiments without departing from the scope of the present invention, and that the description and illustrations therein are illustrative in nature and not limiting. this invention.
[0026] The invention provides a ship, which includes a gas supply system, a gas engine and a gas pipeline system, and the gas pipeline system is connected between the gas supply system and the gas engine. The gas pipeline system transports the gas in the gas supply system to the gas engine for use as fuel.
[0027] The gas pipeline system consists of multiple sections of pipelines connected in sequence for the passage of gas. The gas pipeline system is described below by taking the two-section pipeline as an example.
[0028] refer to figure 1 , this e...

The invention relates to a ship, a gas pipeline system and a grounding method of the gas pipeline system. The fuel gas pipeline system comprises a first pipeline and a second pipeline through which fuel gas passes, and flanges which are separately fixed at pipe openings of the first pipeline and the second pipeline, wherein the two flanges are connected and fixed through a fastener; fixing holes are formed in the peripheral side of each flange; the gas pipeline system further comprises fasteners and connecting lines, one ends of the fasteners are nailed into the fixing holes, and the other ends of the fasteners extend out of the peripheries of the flanges outwards; two ends of the connecting line are connected with one fasteners on the two flanges respectively; and the fastener on one flange is connected to a peripheral electrostatic structure through a grounding line, so that static electricity can be conducted outwards, the potential explosion risk caused by electrostatic sparks is avoided, and the gas pipeline system is more stable and reliable. The fixing holes are formed in the flanges, the fasteners are nailed into the fixing holes, and a welding process does not need to be carried out on the flanges, so that the flanges cannot be damaged due to thermal deformation, and the structures of the flanges are protected.
Description
technical field [0001] The invention relates to the field of ships, in particular to a ship, a gas pipeline system and a grounding method thereof. Background technique [0002] Gas has become one of the main energy sources of modern life. In the fields of daily life and shipping, the use of gas has become very common. In order to realize the transmission of gas, a large number of gas delivery pipes are required, and the gas connection flange is the connecting device for the gas delivery pipe. When the gas connection flange is in use, it is easy to generate high-voltage static electricity, and once there is gas in the delivery pipe, the static electricity may cause spark discharge, resulting in combustion and explosion of the gas, which poses a serious safety hazard. In the field of ship transportation, according to the requirements of classification societies, all gas pipeline systems need to be safely and effectively electrostatically grounded to ensure that when the syste...
