Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refueling equipment, and particularly relates to a refueling combined valve capable of controlling the refueling volume.
Background Art
[0002] In the currently used fuel dispensers, the connection between the fuel gun and the oil tank is realized through a valve group, and the refueling of the vehicle and the metering of the flow rate are realized by controlling the opening and closing of the electromagnetic valves in the valve group.
[0003] There is a common defect in the currently used fuel dispensers, that is, when refueling, the refueling flow rate remains constant. When refueling a vehicle with a large fuel tank, the waiting time required to fill the fuel tank is relatively long.
Content of the Utility Model
[0004] To solve the above problems, the purpose of the utility model is to provide a refueling combined valve capable of controlling the refueling volume, which can adjust the refueling flow rate according to the size of the fuel tank of the vehicle to be refueled.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a refueling combined valve capable of controlling the refueling volume, which sequentially includes a ball valve, a filter, a flowmeter and an electromagnetic valve from top to bottom. Among them, the ball valve, the filter, the flowmeter and the electromagnetic valve are all arranged in series. The electromagnetic valve includes an upper electromagnetic valve and a lower electromagnetic valve, and a through hole with a diameter smaller than the valve port size is arranged on the valve of the lower electromagnetic valve.
[0006] The refueling combined valve capable of controlling the refueling volume in the utility model is further set as: the flow rate that can pass through the through hole is consistent with the flow rate of the small-flow electromagnetic valve.
[0007] The refueling combined valve capable of controlling the refueling volume in the utility model is further set as: both the upper electromagnetic valve and the lower electromagnetic valve are large-flow electromagnetic valves.
[0008] The refueling combined valve capable of controlling the refueling volume in the utility model is further set as: the upper electromagnetic valve and the lower electromagnetic valve are arranged in series and independently controlled to open and close.
[0009] Compared with the prior art, the utility model has the following beneficial effects: the above-mentioned refueling combined valve capable of controlling the refueling volume realizes the switching of the large and small refueling volumes through the form of a combined valve, which is not only simple in structure, but also convenient to control, safe and reliable.

Specific Embodiment
[0012] The following further describes in detail a refueling combined valve capable of controlling the refueling volume in different sizes according to the present utility model through specific embodiments.
[0013] As Figure 1 shown, a refueling combined valve capable of controlling the refueling volume in different sizes sequentially includes a ball valve 1, a filter 2, a flowmeter 3 and a solenoid valve from top to bottom. Among them, the ball valve 1, the filter 2, the flowmeter 3 and the solenoid valve are all arranged in series. The solenoid valve includes an upper solenoid valve 4 and a lower solenoid valve 5. A through hole with a diameter smaller than the valve orifice size is provided on the valve of the lower solenoid valve 5.
[0014] Both the upper solenoid valve 4 and the lower solenoid valve 5 are large-flow solenoid valves. The flow rate that can pass through the through hole is the same as that of a small-flow solenoid valve. The upper solenoid valve 4 and the lower solenoid valve 5 are arranged in series and independently controlled for opening and closing.
[0015] The working principle of the present utility model is as follows: During use, when the upper solenoid valve 4 is opened and the lower solenoid valve 5 is closed, at this time, the oil will flow through the upper solenoid valve 4 and then flow into the vehicle through the through hole of the lower solenoid valve 5 to achieve small-flow refueling. If both the upper solenoid valve 4 and the lower solenoid valve 5 are opened at the same time, large-flow refueling is achieved. Through the form of the combined valve, the switching of the refueling volume in different sizes is realized, which is not only simple in structure, but also convenient, safe and reliable in control.
[0016] The above embodiments only illustratively explain the principle and efficacy of the present invention and some applied embodiments, rather than restricting the present utility model; it should be pointed out that for those of ordinary skill in the art, without departing from the creative concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
