Problems solved by technology

[0005] The switching mechanism of the above-mentioned dual-fuel generator set is only a kind of error-proof design. Although it can ensure that the two switches are not opened at the same time, one switching requires multi-step operations of the switching handle and the switch, which makes the switching operation of fuel oil and gas easier. very complex and slow to switch

Embodiment Construction

[0031] In order to make the above-mentioned technical content and structural features of the present invention more easily understood by those skilled in the art, the present application will be further described below in conjunction with the accompanying drawings and technical points.

[0032] Such as figure 1 and Figure 7 as shown, figure 1 It is the first front view of the oil-gas linkage switching device in the embodiment, Figure 7 It is the second front view of the oil-gas linkage switching device in the embodiment. The oil-gas linkage switching device of the present invention mainly includes a valve body 1 , a valve stem 2 , a micro switch 3 and a handle 4 . in:

[0033] The structural form of the valve body can be varied. However, considering the compactness of the overall structure, in this embodiment, the valve body 1 is designed as a cuboid valve body, such as figure 1 , figure 2 and Figure 4 shown.

[0034] Such as Figure 4 As shown, a fuel passage 5 ...

Abstract

The invention relates to an oil-gas linkage switching device and a working mode thereof. The oil-gas linkage switching device comprises a valve, a valve rod, a microswitch and a handle, a fuel oil channel and a fuel gas channel are transversely arranged on the valve, a valve rod mounting channel is longitudinally arranged on the valve and transversely penetrates the fuel oil channel and the fuel gas channel, a base plate is connected onto the outer wall of the valve, the valve rod penetrates the valve rod mounting channel, a fuel oil valve hole and a fuel gas valve hole are formed in the valve rod, a control end of the valve rod extends out of the valve, the microswitch is mounted on the base plate, a handle hinge base is arranged on the base plate, the handle is hinged onto the handle hinge base, the middle of the handle is linked with the control end of the valve rod, and the handle is turned and can press or loosen a warping plate on the microswitch. When the valve holes are communicated with the fuel oil channel, the microswitch is powered on. When the valve holes are communicated with the fuel gas channel, the microswitch is powered off. The oil using state and the gas using state of a carburetor can be instantly switched by turning the handle, and the oil-gas linkage switching device is simple and convenient to operate.

Description

technical field [0001] The invention relates to an oil-gas linkage switching device and its working mode, which are mainly applied to dual-fuel engines with both oil and gas functions. Background technique [0002] Dual-fuel engine is a new type of generator that can use gasoline fuel and liquefied petroleum gas fuel as fuel. It has the technical characteristics of high efficiency, low pollution, and low emission, and has a good development prospect. [0003] When the existing dual-fuel generator sets are in use, because the gas switch and the fuel switch are located close to each other, and there are no protective measures, the gas switch and the fuel oil switch are often turned on at the same time due to user misoperation. Simultaneously entering the mixed combustion of the engine will cause abnormal operation of the engine, unstable operation, and unsafe flames, etc., which will seriously affect the safety performance of the generator set. [0004] In order to solve the ...
