Abstract
The utility model provides a high speed stop oil electromagnetic valve for diesel engine, mainly comprising a coil winding, and a movable iron core device. The coil winding consists of a suction-drawing coil and a retention coil which are mutually connected in parallel. The coil winding is connected with an electric control protector which mainly consists of an input terminal, balancing resistors, and a field-effect transistor. The input terminal is connected with one receiving terminal of the suction-drawing coil and one receiving terminal of the retention coil through circuits, and connected with the grid of the field effect transistor through the balancing resistor; the other receiving terminal of the suction-drawing coil is connected with the source electrode of the field effect transistor, and grounded; the other receiving terminal of the retention coil is connected with the drain electrode of the field effect transistor; a balancing resistor is also provided between grid of the field effect transistor and the source electrode. The electromagnetic valve is connected with the switch of the key of the engine, and directly acts on the rack bar of the oil valve; as the action of the electric control protector, the reliable durability of the product is improved, and the attack which is caused by the oversize current for the power supply and the circuit system is avoided.
Description
Technical field
The utility model relates to the solenoid valve that car, ship etc. stop working with the diesel engine oil-break.
Background technique
At present, car, ship etc. adopt the ignition by compression mode with diesel engine, not only will close electric switch when diesel engine is flame-out, also must cut off oil pump feed.At present, flame-out with pull bar control diesel engine oil-break, inconvenient operation can not be as petrol engine flame-out and startup by electric switch control.
Summary of the invention
Can not be by the flame-out shortcoming of electric switch control in order to solve present car, ship etc. with diesel engine, the utility model proposes diesel engine and stop solenoid at a high speed, mainly comprise coil winding and moving iron core apparatus, coil winding is positioned at housing, by pull in winding parallel with one another with keep coil and form, moving iron core apparatus is that a moving iron core is positioned at the coil winding in-core and its head is provided with the Returnning spring support, and coil winding is connected with automatically controlled protector; Described automatically controlled protector mainly is made up of input terminal, ballast resistor and field effect transistor, the terminal of input terminal by circuit and pull in winding, terminal of keeping coil are connected, and input terminal also is connected with the grid of field effect transistor by behind the ballast resistor; Another terminal of pull in winding are connected with the source electrode of field effect transistor and ground connection, and another terminal of keeping coil are connected with the drain electrode of field effect transistor; Between the grid of field effect transistor, source electrode, also be connected with ballast resistor.
The moving iron core that described diesel engine is stopped solenoid at a high speed can directly act on the ratch (stopping oily pull bar) of fuel tap.Described solenoid valve is connected with the switch of motor by the input terminal of automatically controlled protector; after the diesel engine electric switch is opened; pull in winding and keep coil simultaneously; under automatically controlled protector transducing signal; pull in winding produces maximum magnetic force inspiration piston under heavy current; open oil circuit; keeping coil keeps moving iron core and is in and retreats under the light current effect; make oil circuit unimpeded; utilize the recurrent pulses control technique (duty of ratio of field effect transistor; pulse width can be adjusted); make and the pull in winding stable working of solenoid valve reduce of the wearing and tearing of the big active force of moving iron core other device.The utility model main feature is the structure of electric seed protector, has improved the product reliable durable, makes the product physical life by original 1-2 ten thousand times, is increased to 5-10 ten thousand times; By the big electric current inhibitory action of field effect transistor, avoided excessive suction to draw the impact of electric current to power supply and circuitry.
When the motor electric switch cuts out, pull in winding and keep coil outage simultaneously at a high speed, moving iron core return under the effect of Returnning spring is closed oil circuit, the oil pump fuel cut-off.
Described diesel engine stop at a high speed solenoid by the line adjusting pull in winding and keep coil directly than, adopt different winding combining forms simultaneously, can conveniently obtain the serial solenoid valve product of different strokes, different pulling force requirements, the phenomenon of product " low load with strong power " before overcoming, the power consumption of reduction product.
Generally speaking, load onto the described solenoid that stops on motor, flame-out and startup is easy for operation by electric switch control; By automatically controlled protector stabling current, avoid pull in winding, keep coil and burnt out, guarantee the trouble free service of electric component, improve the working life that stops solenoid.
