Abstract

The utility model discloses a gas flow control device for a gas fuel engine or a dual-fuel engine wherein, at least two or more electromagnetic valves are connected in parallel between a gas inlet channel and a gas outlet channel; the gas inlet channel can be communicated with the gas outlet channel through the valve of each electromagnetic valve; the gas inlet channel and the gas outlet channel are arranged in the same shell body; a gas inlet joint is connected on the port of the gas inlet channel; the drive electric signals of each electromagnetic valve are three drive signals, namely, a low-level signal, a high-level signal and a digital pulse signal. With the small-diameter electromagnetic valves, the utility model has the advantages of high accuracy in flow control and can meet fuel demands in any engine load.

Description

The gas flow control device of motor
The utility model relates to a kind of being used for and is the motor of fuel or is the engine gas flow control device of the duel fuel engine of fuel with fuel oil and combustion gas with rock gas or other combustion gas, belongs to the fuel gas technical field of engines.
At present, two kinds of methods of the general employing of the gas flow of fuel gas motor of the prior art control, a kind of is to adopt the proportional electromagnetic valve of a big latus rectum to come the aperture of control valve to reach the purpose of control gas flow by given ratio-voltage; Another kind method is that the aperture that adopts stepper motor to control vent valve reaches the purpose of controlling gas flow.Though these two kinds of methods are simple, motor all requires valve to have the latus rectum of big flow to the needs of fuel when satisfying full load, this large-capacity valve, because its aperture is all bigger, therefore often its control accuracy is all poor, can not satisfy the accurate control to gas flow.
The purpose of this utility model is: provide a kind of flow control accuracy higher, and can satisfy under gas engine maximum load and any load condition gas flow control device to the motor of fuel gas demand.
The utility model is to constitute like this: it comprises solenoid valve (1) and gives the combustion gas gas-entered passageway (2) and the combustion gas outlet passageway (3) of motor delivery of fuel gas, two or more solenoid valves (1) at least that are equipped with in parallel between gas-entered passageway (2) and outlet passageway (3), gas-entered passageway (2) can be connected with outlet passageway (3) by the valve of each solenoid valve (1); Under normal conditions, best three solenoid valves in parallel (1) between gas-entered passageway (2) and outlet passageway (3); Gas-entered passageway (2) and outlet passageway (3) can be located in the same housing (4), and in housing (4), be provided with the combination gas air feed channel (5) and the blast tube (6) that can be connected with the intake duct on the motor, blast tube (6) is communicated with outlet passageway (3) with combination gas air feed channel (5), be connected with suction tude joint (7) on the port of gas-entered passageway (2).
Owing to adopted technique scheme, the utility model compared with prior art, because the utility model is to adopt several solenoid valves to be in parallel to control gas flow, therefore under the situation of the big flow of combustion gas, can adopt the solenoid valve of less latus rectum to control, because the opening ratio of the solenoid valve of each little latus rectum is less, thereby solenoid valve drives under the electrical signal control at it, the quick acting flexibly and accurately of each solenoid valve, therefore it is higher to the utlity model has flow control accuracy, and can satisfy the advantage of fuel gas demand under gas engine maximum load and any load condition.When using the utility model, can adopt in the prior art can output low level, the electronic controller ECU of high level and three kinds of drive signals of digital pulse signal is as the driving electrical signal of solenoid valve of the present utility model.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the A-A cross-sectional schematic of accompanying drawing 1;
Schematic representation when accompanying drawing 3 uses for the utility model.
The component names of each sequence number is respectively in accompanying drawing 3: (8) gaseous-pressure sensor, (9) fuel gas temperature sensor, (10) air inlet pressure sensor, (11) intake air temperature sensor, (12) speed probe, (13) throttle position switch, (14) exhaust gas temperature sensor, (15) gas cylinder, (16) high pressure filter cleaner, (17) gas pressure reduction system, (18) engine inlets, (19) motor, (20) engine exhaust pipe, (21) high-pressure air pipe, (22) low pressure tracheae, ECU is an electronic controller, SC is the drive signal follower, and these parts all are the finished product of prior art.
Embodiment of the present utility model: adopt conventional low level, three kinds of electrical signal of high level and digital pulse signal are as the drive signal of each solenoid valve (1), make each solenoid valve when its driving electrical signal is low level, solenoid valve is for cutting out, when its driving electrical signal is high level, its solenoid valve is a standard-sized sheet, when its driving electrical signal is digital pulse signal, the switching working state of its solenoid valve is modulated by the drive pulse signal width, during concrete the making, its solenoid valve (1) can adopt the finished product of selling on the market to assemble, gas-entered passageway (2) and outlet passageway (3) are produced in the same housing (4), and in housing (4), produce a combination gas air feed channel (5) that can be connected and a blast tube (6) with the intake duct on the motor, blast tube (6) can be communicated with outlet passageway (3) with combination gas air feed channel (5), on the port of gas-entered passageway (2), connect a suction tude joint (7), between gas-entered passageway (2) and outlet passageway (3) according to employed engine power situation two or more solenoid valves (1) at least of loading onto in parallel, be installed in parallel three solenoid valves (1) in the ordinary course of things and get final product, gas-entered passageway (2) can be connected with outlet passageway (3) by the valve of each solenoid valve (1).
When adopting the utility model, the utility model is installed on the existing duel fuel engine (19), when motor (19) operates in the double fuel working state, after natural gas via high pressure filter cleaner (16) in its gas cylinder (15) filters, be reduced to the pressure of setting by gas pressure reduction system (17), be transported to suction tude joint (7) then, engine operating parameter and throttle position instruction that while ECU electronic controller is experienced according to each sensor, calculate total fuel consumption required under the present engine normal working and combustion gas requirement, determine the mode of operation of three solenoid valves (1) then according to the size of required combustion gas, be that the control signal sent of ECU is operated in respectively by drive signal follower SC three solenoid valves of control (1) and closes, under standard-sized sheet or three kinds of mode of operations of pulse signal width modulation, its gas quantity is determined by the combined situation of three solenoid valves (1), behind quantitative combustion gas process combination gas air feed channel (5) and air mixing, be transported in the motor (19) by engine inlets (18) again, thereby guarantee the proper functioning of motor.
