Electromagnetic type four-channel rotary switching valve for automobile refueling

Abstract

The invention discloses an electromagnetic type four-channel rotary switching valve for automobile refueling. The electromagnetic type four-channel rotary switching valve comprises an oil inlet system, baffles, an electromagnetic controller, standing valve shells, a rotary valve element, a flow diversion control valve body and oil outlet pipes. The baffles comprise the left baffle and the right baffle, and the top of the left baffle and the top of the right baffle are each provided with a reset spring. The electromagnetic controller is composed of a power source, an electromagnet, static contacts, movable contacts and armatures, wherein the static contacts are inlaid on the standing valve shells, the movable contacts are inlaid on the valve element, and the armatures are arranged at the bottoms of the baffles. A drainage pore passage is arranged inside the rotary valve element, and the rotary valve element is covered with a layer of oil leakage prevention seal sleeve; the outer end of the rotary valve element is connected with a connecting rod and a handle; the bottom of each standing valve shell is connected with two oil outlet pipes. The electromagnetic type four-channel rotary switching valve for automobile refueling aims at the automobile carrying four fuel oil tanks, performs control over switching among the oil tanks in the refueling process and can prevent mutual contamination caused by oil gas volatilization among the oil tanks.

Description

technical field [0001] The invention relates to the technical field of refueling control for vehicles with multiple fuel tanks, in particular to an electromagnetic four-channel rotary switching 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 ignition performance; dies...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide an electromagnetic four-channel rotary switching valve for automobile refueling. For a car carrying four fuel tanks, a refueling switching device is provided under the fuel filler, and the fuel filler can be switched to different fuel tanks as required to realize different fuel tanks. Add fuel to the fuel tank; after the fuel is added, close the ports of each fuel tank, which can solve the technical problem of mutual pollution caused by volatilization of oil and gas between the fuel tanks
