Abstract
The invention discloses an oil path system and oil path switching valve of an oiling vehicle. The oil path switching valve comprises a valve body and a valve element arranged in the valve body. At least two pairs of liquid flowing holes distributed in the radial direction of the valve element are formed in the valve body. A liquid switching passageway penetrating the columnar valve element in the radial direction is arranged on the valve element. Liquid switching through grooves are formed in the surface of the columnar valve element in the axial direction of the columnar valve element. The liquid switching passageway and the liquid switching through grooves are arranged in a spaced manner. At a first switching position, the liquid switching passageway abuts against a pair of liquid flowing holes in the radial direction of the valve body to form a first sealing passageway, and meanwhile the liquid switching passageway is not communicated with the liquid flowing holes. At a second switching position, the liquid switching through grooves abut against a pair of liquid flowing holes in the axial direction of the valve body to form a second sealing passageway, and meanwhile the liquid switching passageway is not communicated with the liquid flowing holes. According to the valve, the number of valve elements can be reduced, and complexity of pipeline wiring and operation can be lowered.
Description
Technical field
The present invention relates to a kind of oil circuit, be specifically a kind of oil-way system of refuelling truck, also relate to the oil passage change-over valve being exclusively used in this oil circuit, belong to fluid and pipeline corollary equipment technical field.
Background technique
Current domestic refuelling truck generally adopts pipeline flow process as shown in Figure 1, and its drawback is that flowmeter outlet exists branch road, causes the flow loss having branch road during fueling operation, the accuracy of impact metering, need 3 ball valve group closing operations in addition, pipeline is complicated, troublesome poeration.Also have the pipeline flow process adopting flowmeter outlet without branch road, as shown in Figure 2, its feature is to utilize valve a, valve b and valve c to combinationally use change runner, and complete oil pumping operation, its drawback is that the cost of three two-way valves is high, and pipeline is complicated, and complex operation.The refuelling truck also had in order to reduce the complexity of operation, employing be replace three two-way valves with two three-way valve, as shown in Figure 3, but no matter use three two-way valves or two three-way valve, all there is the problem of the many and complicated operation of pipeline wiring complexity, components and parts.Valve is improved for these problems through retrieving and finding no people.
