Description

Generator with pressure reducing valve Technical Field The invention relates to a generator using fuel gas as fuel, in particular to a generator with a pressure reducing valve. Background The generator with the pressure reducing valve is a generator using gas fuel (such as natural gas, coal gas, etc.). When the gas fuel is delivered to the generator, the pressure of the gas fuel is required to be reduced and regulated through a reducing valve, so that the use of a power unit of the generator is met. However, in actual use, the pressure of the gas fuel will change, when the pressure of the gas fuel is seriously insufficient, the power unit of the generator will be under the condition of serious power shortage, if the generator works for a long time under the condition of serious power shortage, the generator is easy to be damaged, and the service life of the generator is seriously affected. However, it is difficult for an average user to find whether the generator is in a state of serious power shortage. The Chinese patent document CN119244380A discloses a gas mixing control device of an LPG generator set, which comprises a gas engine, a premixed vortex gas inlet chamber, a proportional dynamic response component, an adjusting control component and a proportional adjusting controller, wherein the gas engine is arranged in a protective engine body, an air inlet end is formed at the top of the gas engine and is used for forming a power source to drive the whole device, the top end of the premixed vortex gas inlet chamber is communicated with the proportional adjusting controller through a self-adaptive multi-source gas inlet valve pipe and is used for enabling the entering gas and air to be fully premixed before entering the internal combustion chamber of the gas engine through an internal vortex structure, the proportional dynamic response component is arranged at the inner side end of the protective engine body and is communicated with a gas guide manifold and is used for dynamically adjusting and controlling the gas mixing proportion under different load and environmental temperature changes, the top end of the adjusting control component is communicated with a multi-stage mixing chamber and is used for gradually thinning the mixing process of the gas and the air in the multi-stage mixing chamber, and the bottom end of the proportional adjusting controller is communicated with the air flow adjusting chamber through a control valve pipe and the air flow adjusting chamber. According to the technical scheme, accurate mixing proportion control is realized under the cooperation of the proportion dynamic response component, and the optimal gas mixing proportion and flow demand under the current working condition are predicted, so that when the propane content in the LPG is increased, the model prediction controller properly reduces the gas inlet amount and increases the air amount, the full combustion is ensured, the mixing proportion and flow can be quickly corrected, the combustion process is quickly restored to be stable, the gas engine is ensured to stably run under different loads, the whole device forms flow balance and stable operation, the actual combustion effective components are accurately judged under the difference of different gas sources and LPG components, the required gas and air amount are accurately calculated, the accurate mixing proportion control is realized, and meanwhile, the accurate control on the gas mixing process is realized under the cooperation of the regulation control component. However, the structure of the prior art scheme is complex, so that the manufacturing cost of the generator can be obviously increased, and the popularization and the application are not facilitated.
