Air supply device for liquefied petroleum gas moped

Abstract

The invention relates to an air supply device for a liquefied petroleum gas moped, which comprises an air pipeline and a fuel valve arranged on the air pipe, wherein the fuel valve comprises a valve seat, a valve cap, an air filling valve rod, an air inlet regulating arm, a locking nut, a rubber membrane and a torsional spring; the valve seat is fixedly connected with the air pipeline, and the valve seat and the air pipeline are integrated by one-step forming; a central through hole, an inlet hole and a fine-adjustment hole are formed on the valve seat; the valve cap is fixed on the valve seat through a bolt; the air inlet regulating arm is fixed to the upper part of the air filling valve rod through the locking nut; the torsional spring is sleeved on the air filling valve rod; a wire drawing limiting stopper is fixed to the lower part of the front end of the air pipeline, and a supercharger is arranged at the rear of the air pipeline; and the supercharger is communicated with the air pipeline through an air pipe. Compared with the prior art, the air supply device has the advantages of compact structure, complete functions, stable function, high pressure regulating accuracy and the like.

Description

(1) Technical field: [0001] The invention relates to a gas supply device, in particular to a liquefied petroleum gas supply device for a power-assisted vehicle. (two) background technology: [0002] With the rapid development of the national economy and the continuous improvement of people's living standards, mopeds as a means of transportation have become more and more popular. The existing mopeds mainly include fuel type and battery type. It emits harmful exhaust gas and is popular for being environmentally friendly. Its disadvantage is that the travel distance is short, and each battery can only run about 30 kilometers. Therefore, it is necessary to disassemble the battery frequently for charging, which is not only troublesome, but also needs to be replaced with a new battery every year, which is expensive; and The vast majority of fuel-powered mopeds use gasoline as fuel. Due to the rising price of gasoline, the cost of using the moped has been greatly increased. In addi...

[0002] With the rapid development of the national economy and the continuous improvement of people's living standards, mopeds as a means of transportation have become more and more popular. Existing mopeds mainly include fuel type and battery type. It emits harmful exhaust gas and is popular for being environmentally friendly. Its disadvantage is that the travel distance is short, and each battery can only run about 30 kilometers. Therefore, it is necessary to disassemble the battery frequently for charging, which is not only troublesome, but also needs to be replaced with a new battery every year, which is expensive; and The vast majority of fuel-powered mopeds use gasoline as fuel. Due to the rising price of gasoline, the cost of using the moped has been greatly increased. In addition, after the combustion of gasoline, its carbon monoxide content is as high as 4%, and the hydrocarbon content is as high as 8500ppm. Exhaust gas not only causes serious pollution to the air, but also endangers human health
