Dual gas source fuel gas conversion valve apparatus

Abstract

The invention relates to a conversion valve used for a fuel gas generator employing multiple kinds of fuel, and specifically relates to a dual gas source fuel gas conversion valve apparatus. The apparatus comprises a valve body, a gas inlet and a gas outlet through which double gas sources can go in and get out, and a valve core provided with a handle. One end of the valve body is provided with a valve core hole, and the other end of the valve body is provided with the gas outlet. The gas inlet is located on the side wall of the valve body, and is vertically communicated with the gas outlet and the valve core hole. A gas passage is arranged between the gas inlet and the gas outlet. The valve core passes through the valve core hole and the gas inlet sequentially, and opens or closes a part of gas vents in the gas passage. The apparatus is designed in a manner that the fuel gas is switched through the gas inlet and the gas outlet which are equal in size, the unique valve core and the gas passage, so that shortcomings that a conventional conversion valve in the same industry at abroad is complex in structure and inconvenient to operate can be overcome. The apparatus is small in size, is light in weight, and saves the space. The gas passage has a gas output fine tuning function, the adjusting manner is high in accuracy, and the gas supply amount can be well controlled. Furthermore, the gas inlet and the gas outlet of the apparatus can be mutually replaced, so that the apparatus is more convenient to use.

Description

technical field [0001] The invention relates to a switching valve used in a small and medium-sized multi-fuel gas generator, in particular to a dual gas source gas switching valve device. Background technique [0002] With the widespread use of new energy sources such as clean energy natural gas, petroleum liquefied gas, and biogas, even domestic, commercial, and industrial generator sets that use gas as fuel are widely used in the world. However, the use of different fuels requires a device to switch fuels so that the engine can work normally on different fuels. The fuel conversion valve device used in the traditional two-fuel gas generator set needs to be equipped with multiple sets of different air inlets and outlets, which has the disadvantages of complex structure, and the need to use tools to disassemble the pipeline for fuel replacement. In addition, the adjustment of the air supply volume of the gas valve in the prior art is realized through the opening and closing ...

AI Technical Summary

Problems solved by technology

The fuel conversion valve device used on the traditional two-fuel gas generator set needs to set up multiple sets of different air inlets and outlets, which has the disadvantages of complex structure, and the need to use tools to disassemble the pipes for fuel replacement.

In addition, the adjustment of the gas supply volume of the gas valve in the prior art is realized by the opening and closing of the gas valve throttle valve backup chamber, which has low precision and cannot control the gas supply volume well.
