Problems solved by technology

[0003] At present, it is quite common for domestic ships to use liquefied gas as kitchen fuel. Liquefied gas is easy to replenish, clean to use, and easy to store and carry. Therefore, liquefied gas cylinders have become common equipment on board, but liquefied gas is a flammable and explosive gas. The storage and use on board should meet the special safety requirements. According to the regulations of Hai 04 / 08 and Hai 11 Chapter 4, gas cylinders should be made of steel materials and stored on the open deck or the opening only faces the open deck. In a well-ventilated place, the gas cylinder should have a reliable fastening device, and the fastened bottle hoop should be easily and quickly disengaged. The bottom of the steel cylinder should have an anti-impact wooden cushion, and the gas is delivered from the gas cylinder to the stove and water heater. The fuel pipeline should be made of steel or other equivalent materials before the pressure reducing valve, and flexible hoses can be used after the pressure reducing valve. Through the above regulations, we can clearly know that the liquefied gas cylinder must have a fixed storage location, It is best to store it in a sheltered open or semi-open place, so that the liquefied gas cylinder cannot be directly put into the kitchen, but can only be stored in a specific location far away from the kitchen and only in front of the pressure reducing valve. Connections are made through piping which shall be constructed of steel or other equivalent material

[0004] Existing gas pipelines made of steel or other equivalent materials will cause flammable gas leakage due to loose connections after connection. If too much flammable gas leaks, it will cause an explosion. If there is a gas leak, an infrared combustible gas detector is generally installed at the connection of the gas pipeline. However, the existing infrared combustible gas detector can only sense whether there is a gas leak within a certain range, and cannot specify the location of the relevant gas leak. Relevant staff further detect the location of the gas leak by seeing, hearing, sniffing or foam inspection. This operation method is inefficient and has certain risks due to the long residence time. When the pipeline is long, the sound and light alarm on the infrared combustible gas detector can only spread a small range, which is not convenient for the staff to detect and discover, resulting in missing the best maintenance time and poor use effect
