Problems solved by technology
Since the air supply pressure of the original air supply system is constant, the air supply is quantified by the valve opening degree, so that when there is no load, the engine air supply volume is too large, resulting in a certain waste

The invention provides a fuel gas use throttling device adjusted according to the state. The fuel gas use throttling device can effectively save fuel gas, improve the utilization rate of fuel gas and reduce emission. According to the technical scheme, a first gas storage chamber is provided with a gas inlet passage through which an external gas source adds gas into the first gas storage chamber, a gas outlet passage of the first gas storage chamber is communicated with a compensation valve, a pressure relieving valve and a gas inlet communicated with a pneumatic control check valve, a gas outlet of the compensation valve and a gas outlet of the pressure relieving valve are converged through a pipeline and then communicated with a gas inlet of a second gas storage chamber, and a gas outlet of the second gas storage chamber is communicated with an engine combustion chamber; a third gas storage chamber is arranged in the second gas storage chamber and provided with a gas inlet hole and a gas outlet which are communicated with the inside of the second gas storage chamber, and the gas outlet is provided with a second check valve only permitting gas to enter the second gas storage chamber from the third gas storage chamber. The fuel gas use throttling device can be widely applied to the field of clean energy.
Description
technical field [0001] The invention relates to a gas-saving device for gas use, and belongs to the technical field of clean energy. Background technique [0002] Entering this century, with the gradual increase in energy consumption, the massive consumption of coal and oil, which are the main fuels that humans have relied on for many years, has aggravated human panic year by year. At the same time, the massive consumption of coal and oil has also brought another kind of Threat - smog. This is also the main public hazard of the current environment, so energy conservation and emission reduction will surely become a challenge and research topic for human beings in the future. [0003] The development and use of natural gas has brought new hope to mankind. The rapid development of the natural gas industry chain in recent years has proved its importance and necessity. The energy consumption in life and production is gradually replaced by natural gas. Natural gas is used in boil...
