Embodiment Construction

[0009] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0010] Such as figure 1 As shown, a high-power pressure reducer for a gas engine. In this embodiment, the situation of two-stage decompression is schematically shown, including a pressure reducer 11, a first-stage decompression gas pipeline 12, and a second-stage decompression gas pipeline. Pipeline 13, total gas pipeline 14 and stepper motor valve 15. The first-level decompression gas pipeline 12 and the second-level decompression gas pipeline 13 communicate with the first-level decompression gas outlet and the second-level decompression gas outlet of the pressure reducer 11 respectively, and communicate with the main gas pipeline 14 respectively. An electric cut-off valve 121 is connected in series on the first-stage decompression gas pipelin...

Abstract

The invention provides a high-power reducer for a gas engine, which overcomes the drawbacks of the prior art. The high-power reducer comprises a reducer body, characterized in that the reducer body is connected with the gas inlet of a stepping motor valve through at least one reduction gas pipeline equipped with an electric stop valve, the gas outlet of the stepping motor valve is communicated with a gas manifold. According to the invention, a double function stepping motor valve controls the gas flow of two pipelines having different pressures; in the prior art, two flow regulating valves are used for controlling the gas flow of the two pipelines having different pressures, which causes control sequence problem, therefore, the invention solves the problem of poor match of gas supply, and improves the control precise. Besides, since only one execution component is used, the cost is lowered, and the system reliability is improved.

Description

technical field [0001] The invention relates to a gas engine, in particular to a high-power pressure reducer of the gas engine. Background technique [0002] The gas engine is an environmentally friendly engine that does not emit black smoke and emits very low harmful gases. With the worldwide oil crisis and environmental pollution, the demand for this environmentally friendly gas engine is becoming more and more urgent at home and abroad. . The biggest difference between a gas engine and a diesel engine is that the fuel system of the diesel engine is canceled and replaced by a gas system and an ignition control system. [0003] Usually, the multi-pressure reducer adopts a single-stage decompression method, which will inevitably result in a weak decompression effect, which is not conducive to the operation of the gas engine. Contents of the invention [0004] The purpose of the present invention is to provide a high-power pressure reducer for a gas engine to solve the de...
