Abstract
The utility model relates to a fuel oil adjusting apparatus, which is mainly used for fuel oil adjustment of a miniature turbine engine. The fuel oil adjusting device mainly comprises a solenoid, a fuel oil control portion and an oil discharge valve. The solenoid is used for controlling the on/off state of fuel oil, the control portion is used for controlling the fuel oil supply rule at the start 10 s of an engine, and normal acceleration of the engine is guaranteed. The housing of the fuel oil adjusting device is provided with a fuel oil inlet joint and a fuel oil return joint which are connected with the fuel oil pipeline of the engine. According to the utility model, the structure is compact, the weight is light, the volume is small, and a large real application value is possessed.
Description
Technical field
The present invention relates to fuel oil controlling mechanism---the fuel oil regulating device that a kind of small turbine engine uses.
Background technique
Fuel oil regulating device, its effect are that the fuel delivery of motor is regulated, and pass through the front 10 seconds accelerating process of the adjusting control engine of fuel oil.All volume is large for general turbogenerator fuel oil regulating device, and complex structure is not suitable for small-sized turbogenerator simple in structure, lightweight requirement.
Summary of the invention
Purpose of the present invention: provide a kind of compact structure, mini engine fuel oil regulating device that reliability is high, in order to regulate the fuel feed rule.
Technological scheme of the present invention: a kind of fuel oil regulating device is characterized in that: it comprises laminate damper 1, film 2, Outflow Valve 3, oil-break valve 4, Fuel Bleed Valve 5, spring 6, adjusting screw 7, assembly of lid 8, fuel oil regulating device housing 9, electromagnetic coil 10; Electromagnetic coil 10 is positioned at the top of fuel oil regulating device; Fuel oil oil-break valve 4 and Outflow Valve 3 lay respectively at the two ends of fuel oil regulating device housing 9; Fuel Bleed Valve 5 is installed on the assembly of lid 8; Adjusting screw 7 is positioned at the bottom of fuel oil regulating device, runs through assembly of lid 8, is connected with film 2; One end of fuel oil regulating device housing 9 is installed Outflow Valve 3 and film 2, connects by spring 6 between Outflow Valve 3 and the film 2; The other end of fuel oil regulating device housing 9 is installed oil-break valve 4 and electromagnetic coil 10, and electromagnetic coil 10 links to each other with the two ends of fuel oil regulating device housing 9 respectively with assembly of lid 8; Laminate damper 1 is housed on the assembly of lid 8; Electromagnetic coil 10 connects oil-break valve 4 by guide rod.
Beneficial effect of the present invention: the present invention is conducive to reduce product weight with electromagnetic coil, fuel-cut valve, fuel oil control section and Fuel Bleed Valve integrated design, the compact product structure.Whole design has realized the filtration of engine fuel, the break-make of fuel feeding and the adjusting of acceleration rule simultaneously.The present invention adds the controller rotating speed only just can be realized whole engine fuel fuel supply rate curve by the adjusting of a screw adjusting, its compact structure, lightweight, development to mini engine fuel oil controlling mechanism has important meaning, and has certain versatility and use value preferably.

Fig. 2 is the external structure of fuel oil regulating device of the present invention;
Wherein, 1-laminate damper, 2-film, 3-Outflow Valve, 4-oil-break valve, 5-Fuel Bleed Valve, 6-spring, 7-adjusting screw, 8-assembly of lid, 9-fuel oil regulating device housing, 10-electromagnetic coil.
Embodiment
The present invention is described in further detail below by embodiment.
Please consult simultaneously Fig. 1 and Fig. 2, the motor energising is started working, the fuel oil of supply engine is through the fuel pump supercharging, filter import from the oil that pump discharge is transported on the fuel oil regulating device, electromagnetic coil 10 is switched on simultaneously, back down oil-break valve 4 by electromagnetic force, fuel oil filters filter through oil and enters nozzle by oil-break valve 4, and nozzle is to the firing chamber fuel feeding.Another road fuel oil of oil-break valve 4 outlet is closed valve to nozzle overflow Fuel Bleed Valve 5 by the road.The overflow fuel oil of nozzle flows out through two pipelines, closes to Fuel Bleed Valve 5(for one), laminate damper 1 and to membrane well, one to Outflow Valve 3.This moment, Fuel Bleed Valve 5 was closed by the nozzle input pressure, and oil circuit is obstructed.Because laminate damper 1 damping function, the pressure on the membrane well left side can't be set up immediately, does not overcome spring 6 elastic force, so Outflow Valve 3 opening, and the overflow fuel oil flows out through Outflow Valve 3, discharges outside the machine by the road.Along with the increase of time, slowly to set up through the pressure of laminate damper 1, fuel pressure promotion film 2 overcomes spring 6 elastic force promotion Outflow Valve 3 and moves to right, outside the fuel oil discharge machine on film right side.Outflow Valve 3 continues to move to right and close, and overflow this moment fuel oil no longer releases outside the machine, and the engine oil amount increases, and gas generator accelerates.
During engine stop work, electromagnetic coil 10 outages, oil-break valve 4 shuts state through the elastic returning of spring to oil circuit, and the oil circuit that leads to nozzle cuts off engine stop work.
In the engine accelerating course, starter motor Fuel Bleed Valve 5 is because the promotion of nozzle oil pressure relief is in the dead position, pass.
The present invention only just can realize the adjusting of whole engine fuel fuel supply rate curve by the adjusting of a screw, its compact structure, lightweight, development to mini engine fuel oil controlling mechanism has important meaning, and has certain versatility and use value preferably.
