Description

Communicating one-way valve for oil tank partition plate

Technical Field

The invention belongs to the field of automobile production and manufacturing, relates to design and transformation of an automobile oil tank, and particularly relates to a communicating one-way valve for an oil tank partition plate.

Background

The military off-road vehicle has the characteristics of large loading mass, large driving range, large difference of driving road conditions and the like, so the length of an oil tank of the military off-road vehicle is generally longer. When a vehicle goes up a steep slope or goes down a steep slope, the oil tank can incline, fuel in the oil tank can flow to the lower end in the oil tank, and even though 1/3-1/4 fuel still exists in the oil tank, the fuel can not be sucked by the oil suction cavity of the oil tank, so that the engine is shut down, and the situation is very dangerous for the running vehicle. In order to solve the problems, the currently adopted method is to design a novel oil tank with high volume utilization rate by adding an oil tank partition plate with an oil through hole in the oil tank, so that the problem that an oil suction cavity cannot suck fuel oil when a vehicle goes up a steep slope or a steep slope is greatly improved, and the running safety of the vehicle on a complex road is improved.

Although this tank is a great improvement over conventional tanks, it has some disadvantages. For example, when the vehicle inclines on a steep uphill slope, the oil passage holes for passing fuel between the different oil chambers gradually leak some fuel to the lower end of the fuel tank, and if the vehicle travels on a steep uphill slope for a long time, the fuel eventually leaks to the lower end of the fuel tank completely, so that the fuel is not sucked into the suction chamber.

In order to achieve the purpose, the technical scheme of the invention is as follows: a communicated one-way valve for an oil tank partition comprises an inclined plane and a valve cover. The lower part of the oil tank partition plate is provided with an inclined plane, an included angle is formed between the inclined plane and the vertical direction, and the inclined plane is provided with an oil through hole which is convenient for oiling the oil tank of the vehicle in order to enable fuel oil to circulate between the oil cavities. The width of the inclined plane is larger than that of the oil through hole, so that fuel oil can smoothly pass through the oil through hole from the side surface, and communication between the oil chambers is realized. The valve cover is rotationally fixed at the top end of the inclined plane, the size of the valve cover is larger than that of the oil through hole, so that the valve cover can cover the oil through hole, and when the oil tank inclines, the valve cover is closed to prevent fuel oil from passing through the oil through hole.

Furthermore, the top end of the valve cover is provided with a fixing part, a pin transversely penetrates through the fixing part, and the pin and the valve cover can rotate relatively.

Furthermore, the communicating one-way valve for the oil tank partition plate further comprises two brackets, wherein the two brackets are welded at the top end of the inclined plane and used for fixing the pins.

Furthermore, two ends of the pin penetrate through the two supports, and the pin and the supports are welded and fixed together.

Furthermore, the oil through hole is circular, so that fuel oil can circulate conveniently.

Further, the middle part of the valve cover is circular, and the middle part is attached to or separated from the oil through hole in the rotating process of the valve cover so as to prevent fuel oil from flowing or enable the fuel oil to pass through the oil through hole.

Further, the bottom end of the valve cover is provided with a counterweight pin, and the counterweight pin generates downward acting force on the valve cover to keep the valve cover vertically downward.

Furthermore, the shape of the counterweight pin is a transversely arranged cylinder, and the counterweight pin and the valve cover are integrally formed, so that the processing is convenient.

The communicating one-way valve for the oil tank partition plate has a simple structure, can ensure the communication between oil cavities in the oil tank when a vehicle runs horizontally, and can play a role in one-way flow limiting when the oil tank inclines, so that an oil suction cavity of the oil tank sucks fuel oil when the vehicle runs on an upward steep slope or a downward steep slope, thereby greatly improving the available fuel oil amount of the oil tank on a slope and the running safety of the vehicle on the slope.
