Abstract

The invention relates to an oil gun. The oil gun comprises a gun body, a gun barrel assembly, a vacuum channel, a gas pipe and a connector. The gun body comprises a liquid channel for oil liquid to pass through and a gas channel for making collected oil liquid steam return to an oiling machine; at least part of the gun barrel assembly is arranged in a gun barrel assembly cavity in the gun body, and the gun barrel assembly comprises a gun barrel and a venturi valve; the vacuum channel comprises a first part extending along the gun barrel and a second part located in the gun body; through arrangement, the venturi valve communicates with the exterior of the oil gun, so that gas is supplemented to the venturi valve; at least part of the gas pipe extends along the gun barrel, through arrangement, the gas pipe is used for collecting the oil liquid steam, and the gas pipe communicates with the gas channel in the gun body; and at least part of the connector is used for fixedly connecting the gas pipe with the gun barrel. The connector is hollow and further communicates the first part, extending along the gun barrel, of the vacuum channel with the second part, in the gun body, of the vacuumchannel, but the vacuum channel does not communicate with the gas channel. The oil gun is convenient to assemble and low in fault rate and maintenance cost.

Description

technical field [0001] The invention relates to the field of refueling equipment, in particular to a refueling gun. Background technique [0002] With the development of science and technology and the improvement of living standards, more and more cars have entered thousands of households. The continuous increase in the number of cars has led to the continuous expansion of the construction of gas stations. In daily life, a gas station includes: an underground fuel storage tank and a plurality of refueling equipment connected to the fuel storage tank. Each refueling device refills the car with oil through the refueling gun on it. [0003] Over a long period of time, the oil vapor generated during refueling can be released into the air in or near the fueling station. However, most of the oil products such as gasoline or diesel oil in gas stations are volatile and have certain toxicity, and their ignition point is still very low, so they are easy to be ignited, posing safety...
