Description
Technical Field
The invention relates to an oil tank conversion valve, in particular to a steel ball rotary oil tank conversion valve.
Background
The oil tank conversion valve is used for controlling the oil passages of the double oil tanks of the automobile. The tank switching valve is also called a main-sub tank switching valve. The main and auxiliary oil tank conversion valve can realize the endurance function: when the user needs, the oil tank A and the oil tank B can be filled with 0 # diesel oil, the oil tank A is used for supplying oil to the engine, and the oil tank B is used for supplying oil to the engine after the oil in the oil tank A is used up. In addition, the main and auxiliary oil tank conversion valve can also realize the function of low-temperature starting: when the user is going to experience cold weather or stay overnight in a cold region, the user can fill the tank A with No. 0 diesel oil and the tank B with No. 35 diesel oil in advance. When cold weather comes or a driver needs to stop and rest in a cold region, before the engine is shut down, the main and auxiliary fuel tank switching valve is used for switching to a fuel tank B (-35 diesel) to cope with the cold weather. After the automobile is converted into the oil tank B, the automobile is required to be operated for a plurality of minutes to ensure that all the oil pipelines of the whole automobile are-35 diesel oil, so that the automobile can be normally started and driven after being flamed out.
The existing oil tank conversion valves at home and abroad are sealed by soft sealing rubber, and the valve gate is opened and closed by up-and-down movement. The disadvantage of this method is that when impurities enter the oil pipe or the interior of the valve body, the sealing effect of the change-over valve is affected, and the change-over valve fails. For example, fig. 1 is a schematic view of a structure of a tank switching valve in the related art. As shown in fig. 1, in the old sealing structure, when the motor or the handle is in the tank a, the upper valve port 19 is opened, the lower valve port 20 is closed, and impurities can appear at the first impurity surface 21; when the motor or handle is in the B tank, the upper port 19 is closed, the lower port 20 is opened, and impurities can appear at the second impurity surface 22.
Therefore, it is necessary to avoid the oil tank switching valve that the sealing effect of the switching valve is affected when impurities enter the oil pipe or the interior of the valve body, and the switching valve fails.
