Embodiment Construction

[0016] Specific embodiments of the present invention will be described in further detail below based on the accompanying drawings. It should be understood that the description of the embodiments of the present invention here is not intended to limit the protection scope of the present invention.

[0017] Please refer to figure 1 and figure 2 , which is a metering valve assembly for a single-channel gas injection system provided by the present invention, including a measuring pipe 110, a valve assembly 170, an actuator 150, an intake air pressure sensor 120, a pipe temperature sensor 130, and a differential pressure sensor , and a controller (not shown).

[0018] The measuring pipe 110 is hollow. In this embodiment, a cylindrical fluid channel is arranged in the middle along the axial direction. The first end has a first flange 111 , and its second end has a second flange 112 . The measuring pipeline 110 communicates with the external pipeline through the first flange 111 a...

Abstract

The invention discloses a metering valve assembly used for a one-channel fuel gas jetting system. An intake pressure sensor, a pipeline temperature sensor and a differential pressure sensor are arranged, a controller calculates flow in a measuring pipeline in real time according to detection signals of the intake pressure sensor, the pipeline temperature sensor and the differential pressure sensorand other fixed parameters and controls an actuator in real time, and therefore the flow in the measuring pipeline is adjusted to be user expected flow in real time. In this way, the fluid flow in afluid channel can be precisely measured, the flow value is rapidly adjusted in real time, and the working response speed of an engine is increased.

Description

technical field [0001] The invention relates to fluid control equipment, in particular to a metering valve assembly for a single-channel gas injection system. Background technique [0002] Gas occupies an important position in the field of world energy supply in the 21st century. Due to the obvious advantages of gas engines in terms of emissions, compared with diesel engines, gas engines emit very little particulate matter, and the emissions of nitrogen oxides, carbon monoxide and hydrocarbons are also significantly reduced, so gas engines are energy-saving and environmentally friendly. Improve the quality of control aspect is of great significance. The gas injection system is used in heavy-duty marine gas engines. In the gas engine, fuel and air need to be introduced, and the intake of fuel or air is controlled through some fluid valves, so that the degree of combustion and the working state of the engine can be controlled. However, the existing fluid valves control the i...
