Background The gas engine is tested in EMC (Electro Magnetic Compatibility ) environment, which requires gas to be powered and stored in a liquid form in a cylinder grid. When the gas in liquid state is conveyed to the gas engine through a pipeline, the pressure of the gas in the steel cylinder grid needs to be reduced through a pressure reducing valve so as to meet the pressure of the normal operation of the engine. At room temperature, the sealing performance of the joint of the pressure reducing valve and the steel bottle grid-collecting screw is good, and the gas cannot leak. When the pressure of the fuel gas is reduced through the pressure reducing valve, the fuel gas is converted from a liquid state to a gas state, a large amount of heat energy can be absorbed, the pressure reducing valve works for a long time, and frosting and even icing can occur at the joint of the pressure reducing valve and the steel bottle grid. The liquid fuel gas is converted into a gaseous state, the condition that the gas leakage occurs due to the hardening of a sealing ring at the joint of a pressure reducing valve interface and a steel cylinder grid collecting thread is caused, the temperature of the pressure reducing valve is low, the internal element is easy to lose efficacy, so that the gas leakage occurs, and according to the condition, the related pipelines are preheated in the process of converting the gas into the gaseous state, so that the pipelines and the pressure reducing valve are ensured to work normally at room temperature, and the gas leakage condition caused by the fact that the pipelines are not tightly sealed due to low temperature and the valve is invalid is avoided.
