Model utility content
The technical problems to be solved in the utility model is to provide a kind of double-direction control regulator, achieves fuel and air mixes according to a certain percentage, improves control accuracy.
For solving the problems of the technologies described above, the technical solution of the utility model is: provide a kind of double-direction control regulator, comprise governor body, be provided with diaphragm in governor body, the inner space of governor body is separated into fuel pressure room and air pressure chamber by diaphragm.Double-direction control regulator also comprises control gear and is installed on the fuel control valve of fuel inlet passage of fuel pressure room, control gear comprises: collection is loaded on RF transmitter on diaphragm, the infrared receiver that is oppositely arranged with RF transmitter and the controller be connected with infrared receiver, controller is connected with RF transmitter, controller is electrically connected with the drive unit of fuel control valve, drive unit is used for the valve rod of driving fuel modulating valve, the spool be fixedly connected with valve rod.
Further, described control gear also comprises: the magnetic field sensor being arranged at the permanent magnet on spool and being connected with controller, magnetic field sensor is arranged on the valve body of fuel control valve.
Further, the air inlet passage of described air pressure chamber is provided with air-regulating valve, air-regulating valve is fixedly connected with diaphragm by a connecting rod.
The beneficial effects of the utility model: RF transmitter is set on diaphragm, infrared receiver is oppositely arranged with RF transmitter, controller detects diaphragm by RF transmitter and infrared receiver and obtains travelling speed, thus pass through the inlet of fuel adjusting valve regulation, the position that diaphragm is being preset is made to reach state of equilibrium, to reach fuel and air mixes in certain proportion, control accuracy is improved.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of the utility model double-direction control regulator.
Fig. 2 is the circuit block diagram of the utility model double-direction control regulator.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment: as shown in Figure 1 and Figure 2, a kind of double-direction control regulator comprises governor body 1, diaphragm 2, connecting rod 3, air-regulating valve 4, fuel control valve 5 and control gear 6.
Particularly, diaphragm 2 is arranged in the internal cavity of governor body 1, and, this diaphragm 2 by the internal cavity of governor body 1 every being divided into fuel pressure room 11 and air pressure chamber 12.
Fuel pressure room 11 is provided with fuel inlet passage 110, and fuel control valve 5 is arranged on fuel inlet passage 110.Fuel pressure room 11 is provided with fuel output channel 111.
Air pressure chamber 12 is provided with air inlet passage 120, air inlet passage 120 is provided with fuel control valve 5, one end of connecting rod 3 is fixedly connected with fuel control valve 5, and the other end of connecting rod 3 is fixedly connected with diaphragm 2.
Fuel control valve 5 comprises drive unit 50, valve rod 51 and spool 52, this drive unit 50 comprises motor-drive circuit 500, the stepper motor 501 be electrically connected with motor-drive circuit and the gear train meshing with stepper motor 501 rotatingshaft, gear train and valve rod 51 meshing, spool 52 is fixedly connected with valve rod 51.
Control gear 6 comprises the infrared receiver 61 that collection is loaded on RF transmitter 60 on diaphragm 2, is oppositely arranged with RF transmitter 60, the controller 62 be connected with infrared receiver 61, collects the permanent magnet 63 that is loaded on spool 52 and collect the magnetic field sensor 64 be loaded on valve body, this magnetic field sensor 64 is connected with controller 62, and the output terminal of controller 62 is connected with motor-drive circuit 500.
Working principle of the present utility model: when motor does not work, the aperture of air inlet passage 120 is maximum, and the force value of fuel pressure room 11 and the force value of air pressure chamber reach balance, and diaphragm 2 remains static, during engine operation, fuel pressure room 11 produces negative pressure, the pressure of air pressure chamber 12 is greater than the pressure of fuel pressure room 11, diaphragm 2 is moved to away from air pressure chamber 12 under pressure, diaphragm 2 drives air-regulating valve 4 to move by connecting rod 3 while moving, the sectional area of air inlet passage 120 is reduced, meanwhile, RF transmitter 60 moves along with the motion of diaphragm 2, controller 62 calculates the movement velocity of diaphragm 2 by transmitting-receiving infrared rays time of RF transmitter 60 and infrared receiver 61 and ultrared length thus calculates the pressure difference of fuel pressure room 11 and air pressure chamber 12, controller 62 is according to calculating data thus controlling the rotation angle of spool 52 to control the aperture of fuel control valve 5, with fuel metering inlet, make the pressure of fuel pressure room and the pressure balance of air pressure chamber 12, avoid because of fuel inlet be not suitable for fuel pressure room and air pressure chamber 12 does not reach state of equilibrium.Spool 52 arranges permanent magnet to detect the actual rotation angle of spool 52, avoid making the actual rotation angle of spool 52 and controller 62 control rotation angle because of gear train transmission inconsistent, thus make fuel inlet precisely controlled, and fuel and air mix according to a certain percentage.
These are only mode of execution of the present utility model; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing the utility model specification and accompanying drawing content to do; directly or indirectly be used in the technical field that other are relevant, all in like manner within scope of patent protection of the present utility model.
