Abstract
The runaway of diesel engine solenoid valve, comprise valve body and oil cut-off valve assembly, be characterized in having on the valve body diesel oil passage and oil-break valve chamber, the oil cut-off valve assembly, comprise electromagnet and oil cut-off valve, electromagnet is fixed on the lower end surface of valve body, and it is corresponding with oil cut-off valve, it is indoor that oil cut-off valve is installed in oil cut-off valve, and oil cut-off valve comprises flap, valve rod, Returnning spring, fixedly connected with the spring seat of honour in the valve rod upper end, Returnning spring is sleeved on the valve rod, and fixedlying connected with the upper-end surface of flap after passing the spring lower seat that adds oil seal ring in the valve rod lower end, is equiped with safety enclosure at the upper end-hole place of oil-break valve chamber.This solenoid valve can be installed on the diesel engine of all models; When diesel engine " driving " or other reason are occurring and can't make engine shutdown, can make engine shutdown rapidly.This solenoid valve is made simple, reliability height, economy and durability; Can exempt driver's operation personnel, maintenance man diesel engine is taken place the worry of " driving ".
Description
(1) technical field
The utility model relates to a kind of diesel engine fuel cutting-off system, and particularly a kind of diesel engine is prevented " driving " solenoid valve.
(2) background technique
Diesel engine is when starting, and " driving " accident happens occasionally.If untimely and take measures rapidly, diesel engine is shut down, will cause the inner body of diesel engine to damage, when serious, body is punctured after also can making the connecting rod screw fracture.The diesel engine speed of this moment has lost control.Shut down handle by diesel engine and can't make diesel engine parking.Must use improper means to shut down, existing method one is: the method that disconnects oil circuit or obstruction suction tude can make diesel engine shut down, this method is feasible, but diesel engine is owing to its inertia also can remain in operation, cause the diesel oil of diesel engine cylinder inner accumulated too much, though diesel engine has stopped running, when diesel engine starts once more, because the diesel oil of diesel engine cylinder inner accumulated too much might take place once more; The method of stopping up suction tude can make operator's time near or that delay of disembarking longer, if after the connecting rod screw fracture, connecting rod can puncture the personal safety that body threatens operator; The 2nd: the driver of use diesel engine hangs speed changer into speed change and keeps off, depress automatic pedal, engage the clutch, the pressure diesel engine shuts down, and this method is feasible, still, as a fresh driver who has never seen " driving ", can be at a loss, and making in this way blindly, very big loss can be caused.At present, knowledgeable people both domestic and external is setting about research erection unit on diesel engine, can effectively control the generation of " driving " accident.
(3) summary of the invention
The technical problems to be solved in the utility model provides a kind of when " driving " accident takes place diesel engine, the novel fuel cutting-off system of diesel engine oil circuit can be cut off rapidly, anti-" driving " solenoid valve of diesel engine of the damage of diesel engine and operator's injury can be avoided.
The technological scheme that adopts is:
The runaway of diesel engine solenoid valve comprises valve body and oil cut-off valve assembly.Diesel oil passage and oil-break valve chamber are arranged on the valve body.The oil cut-off valve assembly comprises electromagnet and oil cut-off valve.Electromagnet is fixed on the lower end surface of valve body, and corresponding with oil cut-off valve.It is indoor that oil cut-off valve is installed in oil cut-off valve.Oil cut-off valve comprises flap, valve rod, Returnning spring.Fixedly connected with the spring seat of honour in the valve rod upper end, Returnning spring is sleeved on the valve rod, fixedlys connected with the upper-end surface of flap after passing the spring lower seat that adds oil seal ring in the valve rod lower end.Upper end-hole place at the oil-break valve chamber is equiped with safety enclosure.Valve body is made of copper.
The oil outlet of above-mentioned solenoid valve is installed on the filler opening of diesel injection pump, and the diesel oil flexible pipe that the diesel oil filter is drawn is fixed on the Fuel Cut Solenoid Valve filler opening by the oil return screw again.
This solenoid valve can be installed on the diesel engine of all models; When diesel engine " driving " or other reason are occurring and can't make engine shutdown, can make engine shutdown rapidly.This solenoid valve is made simple, reliability height, economy and durability; Can exempt driver's operation personnel, maintenance man diesel engine is taken place the worry of " driving ".

Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model circuit diagram.
(5) embodiment
The runaway of diesel engine solenoid valve comprises valve body 6 and oil cut-off valve assembly.Diesel oil passage 13 and oil-break valve chamber 14 are arranged on the valve body 6.The oil cut-off valve assembly comprises electromagnet 4 and oil cut-off valve.Electromagnet 4 is fixed on the lower end surface of valve body 6, and corresponding with oil cut-off valve.Oil cut-off valve is installed in the oil-break valve chamber 14.Oil cut-off valve comprises flap 8, valve rod 11, Returnning spring 2.Fixedly connected with the spring seat of honour 12 in valve rod 11 upper ends, Returnning spring 2 is sleeved on the valve rod 11, fixedlys connected with the upper-end surface of flap 8 after passing the spring lower seat 9 that adds oil seal ring 10 in valve rod 11 lower ends.Upper end-hole place at oil-break valve chamber 14 is equiped with safety enclosure 1.Valve body 6 is made of copper.
Anti-" driving " solenoid valve should be installed in the oil outlet 3 of solenoid valve on the filler opening of diesel injection pump when mounted, and the diesel oil flexible pipe of again diesel-oil filter being drawn is fixed on the solenoid valve filler opening 7 by the oil return screw.
Anti-" driving " solenoid valve working principle: the diesel oil of the diesel oil flexible pipe of drawing from diesel-oil filter during the diesel engine proper functioning is through the filler opening 7 of solenoid valve, the solenoid valve of flowing through, and the oil outlet 3 of solenoid valve is connected with the filler opening of Injection Pump.When " driving " accident takes place in diesel engine, operator start electromagnetic valve switch, at this moment, the coil of solenoid valve has electric current to pass through, iron core 5 produces magnetic the flap 8 of oil cut-off valve is inhaled down the diesel oil that cut-out fully enters Injection Pump, make Residual oil formation vacuum in the Injection Pump, cause the diesel oil supply of plunger coupled parts inside to weaken, impel the diesel engine automatic stopping until cutting off fully.
