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

[0019] 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.

[0020] Such as figure 1 , figure 2 with image 3 As shown, the oil-gas switching device for the carburetor mainly includes a gas valve switch 2, a fuel valve switch 3 and a micro switch 4 arranged in the casing 1, and a gas control handle 5 is arranged on the valve shaft of the gas valve switch. , the fuel control handle 6 is arranged on the valve shaft of the fuel valve switch.

[0021] The gas valve switch is opposite to the initial opening and closing state of the fuel valve switch, and the gas control handle and the fuel control handle are linked through the chute 7 and the slider 8, that is, when the gas valve switch is opened, the fuel valve switch is opened simultaneously. When the ...

Abstract

The invention relates to an instant oil-gas switching device for a carburetor and a working mode of the instant oil-gas switching device. The instant oil-gas switching device mainly comprises a gas-fired valve switch, an oil-fired valve switch and a microswitch, wherein a gas control handle is arranged on the valve shaft of the gas-fired valve switch; an oil control handle is arranged on the valve shaft of the oil-fired valve switch; the on-off states of the gas-fired valve switch and the oil-fired valve switch are opposite; the gas control handle and the oil control handle are in transmission connection through a chute and a slider; a cam is further arranged on the valve shaft of the gas-fired valve switch or the oil-fired valve switch; the microswitch is mounted beside the cam; when the cam is rotated, a warping plate on the microswitch is pressed or released; when the oil-fired valve switch is switched on, the microswitch is electrified; a control knob is also arranged on the valve shaft of the gas-fired valve switch or the oil-fired valve switch; the control knob can be rotated to realize instant switching between oil and gas, so that the operation is simple and convenient.

Description

technical field [0001] The invention relates to an oil-gas switching device for a carburetor and its working method, which is mainly applied to a dual-fuel generator for both oil and gas. 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 characteristics of high efficiency and low pollution emission technology, and has a good development prospect. [0003] Dual-fuel generator sets include dual-fuel engines and generators connected to dual-fuel engines. The gas switch and the fuel oil switch are turned on at the same time due to the wrong operation of the operator, and different fuels enter the engine at the same time for mixed combustion, which will lead to abnormal operation of the engine, unstable operation, and unsafe flames, etc., which will affect the safety of the generator set. Performance is seriously affected. [0004] In order to solve the above problems, those ...
