Background technology
When refueling to hydraulic excavator and other construction machinery and equipments, there are differences and habitually do not read specification sheets due to user's educational level after, the liquid level of fuel oil is annotated to maximum scale by processing ease again, thus is easy to cause fuel oil to overflow the situation of fuel tank.Because fuel oil exists the characteristic of expanding with heat and contract with cold, after fuel oil is filled it up with, in course of normal operation, because other various factors such as the heat that oil return, the cooled hot blast of radiator, hydraulic part distribute can cause fuel oil temperature rising, fuel oil in fuel tank to expand, fuel oil is overflowed from oil outlet.Simultaneously when climbing, fuel tank also can be made to tilt when vibrating and rock, and then fuel oil spilling.Actual in the application of construction machinery product, occurred because fuel filling overfill causes the problem of overflowing in working process, the airfilter that this problem also can cause top to breathe is soaked by fuel oil and damages, and affects fuel oil service property (quality), thus reduces the work efficiency of construction machinery and equipment.
At present, for the problem that fuel oil overflows, people also take more measure, and such as increase check valve in parallel, strengthened etc. by fuel tank, but structure is too compact, cost is higher, and causes the degree of utilization in space low, and general effect is not good.
Summary of the invention
Technical matters to be solved by this invention is: to there are differences and habitually do not read after specification sheets processing ease due to user's educational level by fuel filling to maximum scale again, thus be easy to cause fuel oil to overflow fuel tank, in order to solve above-mentioned Problems existing, a kind of overflow oil tank is now provided, effectively prevents fuel oil from overflowing the situation of fuel tank.
The technical solution adopted for the present invention to solve the technical problems is: a kind of overflow oil tank, comprise fuel tank and fuel filler pipe, described fuel filler pipe is fixedly connected on fuel tank top, and be communicated with fuel tank, described fuel tank internal is just also fixedly installed one section of extension pipe to fuel filler pipe place, concrete, the fixed form of extension pipe and fuel tank is welding, and described extension pipe side face offers some through holes near fuel tank upper wall place.When fuel filling in fuel tank liquid level arrive extension pipe bottom time, continue to refuel, liquid level now in extension pipe can rise rapidly, and there is through-flow effect due to the through hole that extension pipe is offered, liquid level outside extension pipe also can rise lentamente, then cannot continue to rise after the liquid level outside extension pipe did not have through hole, now, top of oil-tank just can form the air chamber of certain altitude; Due to difference of pressure effect, the through hole on extension pipe plays guide functions again, and the liquid level in extension pipe is progressively fallen after rise.
In order to play the effect of any one through hole, described some through holes are all on sustained height.
As preferably, convenient design, described extension pipe and fuel filler pipe are straight circular cylinder type, and extension pipe diameter is consistent with fuel filler pipe diameter.
In order to filter out the impurity that may mix in the fuel oil of filling, in described fuel filler pipe, level is fixedly connected with filtering net.
The invention has the beneficial effects as follows: overflow oil tank provided by the invention, by increasing the extension pipe with through hole, when the liquid level of extension pipe outside did not have through hole, because the fuel oil outside extension pipe is not communicated with air, therefore liquid level no longer rose, effectively prevent because fuel up is too much, in use occur the situation of overflowing fuel tank, structure is simple, successful, reduce cost, be suitable for promoting.
