Description

High-volume-utilization-rate oil tank with communicated one-way valve

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 an oil tank with high volume utilization rate.

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.

Disclosure of Invention

In view of the above-mentioned drawbacks, an object of the present invention is to provide an oil tank with a communication check valve and a high volumetric utilization, which ensures the communication between the front cavity, the oil suction cavity and the rear cavity of the oil tank when the oil tank is horizontal, and ensures that the fuel oil flows into the oil suction cavity and prevents the fuel oil from flowing out of the oil suction cavity when the oil tank is inclined. When the vehicle goes up a steep slope or goes down a steep slope, the oil suction cavity can suck fuel oil under the condition of small fuel oil quantity, so that the fuel oil quantity available on the slope of the oil tank and the safety of the vehicle running on the slope are greatly improved.

In order to achieve the purpose, the technical scheme of the invention is as follows: an oil tank with high volume utilization rate comprises a tank body and a common partition plate in the tank body.

The lower part of the partition plate with the communication check valves is provided with a plurality of communication check valves, and each communication check valve comprises an opening inclined plane and a valve cover. An included angle is formed between the opening inclined plane and the vertical direction, the opening inclined plane is provided with an oil through hole, and the width of the opening 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 to realize communication between the oil cavities. The valve cover is rotationally fixed at the top end of the opening inclined plane to ensure that the valve cover can cover the oil through hole. The valve covers on the two partition plates with the communicated one-way valves are positioned in the oil suction cavity and are arranged oppositely, namely, the valve covers point to the oil suction cavity from the front (back) cavity of the oil tank and are in the communication direction of the one-way valves, and otherwise, the valve covers are in the flow limiting direction.

Furthermore, the valve gap includes the fixed part on top, the valve gap body in the middle of and the counter weight round pin of bottom, and three integrated into one piece.

Furthermore, the high-volume utilization rate oil tank provided by the invention also comprises pins and supports, the two supports are respectively fixed at the top end of the inclined plane of the opening, the pins transversely penetrate through the fixing part and the two supports, the pins and the valve cover can rotate relatively, and the pins and the supports are welded together.

Furthermore, the oil through hole is circular, so that fuel oil can circulate conveniently. The valve gap body is circular, and the size of valve gap body is greater than the size of oil through hole, and when high volume utilization ratio oil tank took place to incline, the valve gap closed can prevent that the fuel passes through the oil through hole.

Further, the shape of the balance weight pin is a cylinder arranged transversely.

Furthermore, a plurality of oil through holes are formed in the upper portion of each oil tank partition plate, and the oil through holes are used for fuel oil to flow through.

Furthermore, the lower part of each oil tank partition plate is provided with two opening inclined planes and two valve covers so as to generate a better technical effect.

Furthermore, an oil suction pipe is arranged in the middle of the oil suction cavity and is vertically arranged. Furthermore, two common partition plates are arranged, each common partition plate is provided with a plurality of oil through holes, and the oil through holes are used for fuel oil circulation.

Furthermore, one of the common partition plates is positioned in the front cavity of the oil tank, and the other common partition plate is positioned in the rear cavity of the oil tank.

The high-volume-utilization oil tank with the communicated one-way valve is simple in structure, and an oil tank partition plate communicated with the one-way valve is arranged at the bottom of the oil tank body and plays a role in one-way flow limiting. When the oil tank is horizontal, the communication among the front cavity, the oil suction cavity and the rear cavity of the oil tank is ensured, and when the oil tank is inclined, the fuel oil is ensured to flow into the oil suction cavity and is prevented from flowing out of the oil suction cavity. When the vehicle goes up a steep slope or goes down a steep slope, the oil suction cavity can suck fuel oil under the condition of small fuel oil quantity, so that the fuel oil quantity available on the slope of the oil tank and the safety of the vehicle running on the slope are greatly improved.

As shown in figure 1, two partition plates 3 with communicated one-way valves are arranged in a tank body 1 of the high-volume-utilization oil tank with the communicated one-way valves, and the partition plates 3 with the communicated one-way valves are vertically arranged and fixed on the inner wall of the tank body 1. The valve cover 32 on one partition plate 3 with the communicating one-way valve is arranged opposite to the valve cover 32 on the other partition plate 3 with the communicating one-way valve, namely the valve cover 32 on one partition plate 3 with the communicating one-way valve is positioned in the oil suction cavity 12, and the opening inclined surface 31 is positioned in the front cavity 11 of the oil tank; the other valve cover 32 with a partition communicated with the one-way valve is positioned in the oil suction cavity 12, and the opening inclined surface 31 is positioned in the oil tank rear cavity 13. Thus, the fuel oil is directed from the front (rear) cavity of the fuel tank to the oil suction cavity 12, which is the conducting direction of the one-way valve, and vice versa, which is the current limiting direction.

Similarly, when the vehicle is descending a steep slope, the fuel tank is inclined downward, and the valve cover 32 is rotated by the weight pin 323. The valve cover 32 at the position of the oil tank rear cavity 13 is vertically separated from the oil through hole 311 at the position downwards, and the oil through hole 311 at the position is completely opened; the valve cover 32 at the position of the front chamber 11 of the oil tank is attached to the oil hole 311 at the position to cover the oil hole 311 at the position. Therefore, the fuel in the rear oil tank cavity 13 flows into the oil suction cavity 12 along the flow direction X through the oil through hole 311, and the valve cover 32 prevents the fuel in the oil suction cavity 12 from flowing into the front oil tank cavity 11, so that the fuel in the oil suction cavity 12 is increased, the problem that the fuel cannot be sucked in the oil suction cavity 12 under the condition of less fuel in the oil tank is solved, and the driving safety of the vehicle is improved.

It should be noted that: the above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention.
