Abstract

The invention discloses a linear control four-channel rotating switching valve for automobile oiling. The linear control four-channel rotating switching valve comprises an oil inlet system, a linear control flow diversion control system, a rotating switching valve body and oil outlet pipes. The oil inlet system comprises an oil filler and an oil filling pipe. The linear control flow diversion control system is used for controlling a control line fixed to a rotating valve element under the combined action of the rotating valve element and a reset spring so that the flow diversion controlling action of a baffle can be achieved. A drainage hole channel is formed in the rotating valve element, the rotating valve element is wrapped by a layer of oil-leaking-preventing seal cover, and the outer end of the rotating valve element is connected with a connecting rod and a handle. The bottom of each fixing valve shell is connected with the two oil outlet pipes. The linear control four-channel rotating switching valve is used for an automobile which is provided with four fuel oil tanks and controlling the switching among the oil tanks in the oiling process and can prevent cross pollution of oil gas volatilization among the oil tanks.

Description

technical field

[0001] The invention relates to the technical field of refueling diversion control for automobiles with multiple fuel tanks, in particular to a wire-controlled four-channel rotary switching diversion valve device for refueling. Background technique

[0002] With the rapid development of the automobile industry and the increase of people's awareness of environmental protection, problems such as shortage of oil resources and automobile pollution have become increasingly prominent. Traditional cars are mostly equipped with only a single fuel tank, which means that only one type of fuel can be used regardless of the working conditions. Under abnormal working conditions, to a certain extent, it will aggravate the emission of automobile pollution and the decline of fuel utilization rate, resulting in a waste of resources. According to domestic and foreign researches, gasoline has good volatility, high octane number, strong anti-knock ability, but poor natural igni...
