Abstract
The utility model relates to an opening and closing system of the electromagnetic control throttle valve; wherein, an electromagnet is positioned near a control support and an iron core is hung and fastened on the action end of an operating lever, so that the electromagnet can directly control the operating handle without a flexible shaft, so as to avoid the energy dissipation and deformation of the flexible shaft and improve the work efficiency of the device on one hand, and make the structure more compact, reduce the volume of the whole machine so that the device can be operated more flexibly and agilely on the other hand.
Description
Technical field
The utility model belongs to the throttle control system field, relates in particular to the system of the throttle switching that utilizes magnet control.
Background technique
The system that utilizes solenoid valve to control the throttle switching is common on all kinds of machinery.The throttle open and close system that early stage Italy produces is that solenoid valve is connected on the oil pipe, when need stop in emergency, cut off power of electromagnetic valve and close solenoid valve, thereby the fast shut-off oil circuit is directly controlled the fuel feeding switch.The position that the solenoid valve of this structure is installed is limited to, and must manual control operation handle.
US-built Electromagnetic Control throttle open and close system was located at other places in the equipment with electromagnet afterwards, as shown in Figure 1, the rotation that comes control operation lever 3 by the flexible axles such as wire rope that are connected on the electromagnet, thereby operating grip 4 is resetted under the effect of return spring 42, and the switching of indication throttle.This structure utilizes electromagnet to come resetting of control operation handle 4, can realize general startup-shutdown, and can shut down automatically when the whole set equipment oil pressure is low.But this structure exists following inconvenience in use:
1. because electromagnet is to come the control operation lever to rotate by flexible axle, for reducing remote operated energy loss, guarantee the required pulling force of flexible axle pull operation lever, while is shorter owing to operate lever is pulled the arm of force of holding to rotating axle center, required pulling force is bigger, therefore the cast-iron volume of electromagnetism is all bigger, so that bigger pulling force to be provided;
2. the in use easy stress deformation of above-mentioned flexible axle;
3. because the structure arrangement of device interior, can't link to each other by straight line between electromagnet and operate lever, the general flexible axle of loop-type that adopts links to each other, shearing force according to power transmitting is decomposed situation, flexible axle on the corner should adopt the circular arc corner, flexible axle will occupy the bigger device space like this, form the waste on the space.
Summary of the invention
Main purpose of the present utility model is to provide a kind of and need not by flexible axle, can utilize electromagnet to control the system that throttle opens and closes automatically.
For achieving the above object, the utility model mainly comprises electromagnet, control set, operate lever and operating grip, operate lever and operating grip all are fixed on the control set, and can be around its immovable point rotation, the two ends of operate lever are hook-type buckling end and effect end, its middle part protrudes upward the positive stop end in the restraining groove that formation can be limited in control set, governor spring one end is fixed on buckling end, the other end is fixed on the control set, operating grip is by the returning projection, return spring and hand lever are formed, the returning projection can fasten mutually with buckling end, return spring one end is fixed on the equipment, the other end is fixed on the operating grip with respect to the other end of returning projection, and electromagnet is located at by the control set, and its iron core buckles on the effect end of operate lever.
After adopting said structure, because electromagnet directly buckles on the effect end of operate lever, but direct control operation handle, and need not by flexible axle, compared with prior art, a direction has been avoided the energy loss and the distortion of flexible axle, improved the working efficiency of equipment, its structure is also more compact on the other hand, has dwindled machine volume, and is more convenient flexible when equipment is used.
For increasing the acting force arm of electromagnet, make spatial structure more compact simultaneously, can make the effect end of operate lever be kink shape backward.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a stereogram of commonly using product;
Fig. 2 is a stereogram of the present utility model.
Embodiment
See also shown in Figure 2, the utility model mainly comprises electromagnet 1, control set 2, operate lever 3 and operating grip 4, operate lever 3 and operating grip 4 all are fixed on the control set 2, and can be around its immovable point 31,41 rotations, the two ends of operate lever 3 are hook-type buckling end 32 and are the effect end 33 of kink shape backward, its middle part protrudes upward the positive stop end 34 in the restraining groove 21 that formation can be limited in control set 2, governor spring 35 1 ends are fixed on buckling end 32, the other end is fixed on the control set 2, operating grip 4 is by returning projection 41, return spring 42 and hand lever 43 are formed, returning projection 41 can fasten mutually with buckling end 32, return spring 42 1 ends are fixed on the equipment, the other end is fixed on the operating grip 4 the other end with respect to returning projection 41, it is other that electromagnet 1 is located at control set 2, and its iron core 11 buckles on the effect end 33 of operate lever 3.
Claims (2)
1. Electromagnetic Control throttle open and close system, mainly comprise electromagnet, control set, operate lever and operating grip, operate lever and operating grip all are fixed on the control set, and can be around its immovable point rotation, the two ends of operate lever are hook-type buckling end and effect end, its middle part protrudes upward the positive stop end in the restraining groove that formation can be limited in control set, governor spring one end is fixed on buckling end, the other end is fixed on the control set, operating grip is by the returning projection, return spring and hand lever are formed, the returning projection can fasten mutually with buckling end, return spring one end is fixed on the equipment, the other end is fixed on the operating grip with respect to the other end of returning projection, and it is characterized in that: electromagnet is located at by the control set, and its iron core buckles on the effect end of operate lever.
2. Electromagnetic Control throttle open and close system according to claim 1 is characterized in that: the effect end of this operate lever is kink shape backward.
