Problems solved by technology

[0003] The object of the present invention is to provide a wire-controlled four-channel rotary switching valve for automobile refueling. For a car carrying four fuel tanks, a refueling switching device is provided below the refueling port, and the refueling port is switched to different fuel tanks according to needs. Adding fuel to different fuel tanks; after the fuel is added, closing the ports of each fuel tank can solve the technical problem of mutual pollution caused by volatilization of oil and gas between the fuel tanks

Embodiment Construction

[0018] Concrete structure and working principle of the present invention refer to Figure 1 to Figure 6-4 . The wire-controlled four-channel rotary switching valve for automobile refueling includes an oil inlet system, a wire-controlled diversion control system, a rotary valve and an oil outlet.

[0019] The oil inlet system includes an oil inlet 1 and an oil inlet pipe 2, the two are connected, and the oil inlet pipe 2 is located below the oil inlet 1; the lower end of the oil inlet pipe 2 is connected to the entrance of the herringbone shunt channel of the wire-controlled shunt control system end;

[0020] The wire-controlled shunt control system includes a baffle 5 , a control wire 8 , a pulley 9 , and a return spring 7 . The baffle plate 5 includes a left baffle plate and a right baffle plate, which are respectively located on the side walls of the left channel and the right channel of the herringbone shunt channel, and one end is fixed on the side wall by the rotation p...

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...
