Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0022] The invention provides a design scheme of a gas metering device for a high-power gas engine, which satisfies the precise measurement of the gas flow of the engine, and adjusts the flow according to the actual required flow of the engine, thereby realizing a flow closed loop. The combustion efficiency of the engine is improved, the emission of exhaust gas is reduced, the degree of automation is higher, and manpower and material resources are saved.

[0023] The gas metering device uses three senso...

Abstract

The invention provides a gas metering device of a high-power gas engine which comprises a valve body assembly, an electric control box assembly, a sensor assembly and an electric actuator assembly, the electric control box assembly is arranged above the valve body assembly, the electric actuator assembly is arranged below the valve body assembly, and the sensor assembly monitors flow data in the valve body assembly. The sensor assembly is electrically connected with the electric control box assembly, the electric control box assembly is electrically connected with the electric actuator assembly, and the electric actuator assembly controls the valve body assembly. The gas metering device of the high-power gas engine meets the requirement for accurate metering of the gas flow of the engine,flow adjustment is conducted according to the flow actually needed by the engine, and therefore flow closed loop is achieved. The combustion efficiency of the engine is improved, exhaust emission is reduced, and manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of engine equipment, in particular to a gas metering device for a high-power gas engine. Background technique [0002] In the current gas metering control of gas engines, most of them directly use manual butterfly valves to adjust the gas intake volume, and do not measure the gas flow accurately, which is not conducive to the working efficiency of the engine, insufficient gas combustion, and increased exhaust gas emissions. [0003] After searching the prior art, the utility model with the authorized announcement number CN 203549408 U discloses a gas pressure regulating metering device, which includes a box body and a pressure regulating metering mechanism. The pressure regulating metering mechanism is arranged in the box body. The pressure metering mechanism includes an inlet tee and an outlet manifold, the inlet tee is connected to the outer wall of the box, the filter is connected to the inlet tee, and a ...
