Abstract

The invention relates to an emergent manual car main and secondary oil tank conversion valve, which comprises an electric conversion valve; a planetary gear is connected with a motor shaft of the electric conversion valve through a gear crankshaft; a rotary knob is slidingly mounted in a protection bush; a reset spring is arranged under the rotary knob; a first inner gear is fixedly mounted in the rotary knob; the planetary gear is slidingly engaged with the first inner gear; the planetary gear is engaged with a second inner gear; and the second inner gear is fixedly mounted in a base. According to the emergent manual car main and secondary oil tank conversion valve provided by the invention, the main and secondary oil tank conversion valves can be quickly converted by the configured emergent manual converting rotary knob. The configured planetary gear mechanism has higher speed increasing ratio, so that quick conversion can be realized.

Description

technical field [0001] The invention relates to a switching valve for main and auxiliary fuel tanks of automobiles, in particular to an emergency manual switching valve for main and auxiliary fuel tanks of automobiles. Background technique [0002] Chinese patent 200920288978.7 provides a switching valve for main and auxiliary fuel tanks of an automobile. The main and auxiliary fuel tanks are switched by a motor, which prolongs the service life and reliability of the fuel tank switching valve. [0003] The problem that exists is that when the main and auxiliary fuel tank switching valves of the car fail or the power supply line of the car switching valve fails, the car cannot select the fuel tank. Usually, the switching valve is replaced or the power supply line of the switching valve is repaired. If there is no maintenance condition or no spare switching valve in the field, the automobile will not work, and there is a greater danger. Contents of the invention [0004] Th...
