Drip-proof oil gun

Abstract

The invention discloses a drip-proof oil gun. The drip-proof oil gun comprises a self-sealing type gun body, wherein the self-sealing type gun body comprises an oil outlet, and three or more than three oil drip-proof mechanisms are uniformly arranged on the oil outlet in the circumferential direction of the oil outlet; each oil drip-proof mechanism comprises a baffle and first rotating seats, a second rotating seat is arranged on the oil outlet, and rotating shafts and torsional springs are arranged between the first rotating seats and the second rotating seat; each baffle comprises an outer edge and two side edges, multiple baffles form a polygon-shaped or circular blocking cover in an enclosed mode, and the area of the blocking cover is larger than the area of the oil outlet; and first sealing strips are fixedly connected to the side edges of the baffles, and the first sealing strips of two adjacent baffles are in close contact under the action of the torsional springs. According tothe drip-proof oil gun, the oil drip-proof mechanisms are designed at the position of the oil outlet, the self-sealing type blocking cover is formed in an enclosed mode to block residual oil liquid inthe oil outlet, and the phenomenon of oil liquid volatilization or drippage in the process of lifting and taking the oil gun is avoided.

Description

technical field [0001] The invention belongs to the technical field of petroleum equipment, and in particular relates to an oil drip-proof refueling gun. Background technique [0002] As the number of domestic vehicles continues to increase, the construction of gas stations is also constantly following up. As a fuel supply terminal, how to achieve fuel saving and fire prevention needs to be considered from the fuel dispenser. What is generally used in the prior art is a self-sealing fuel gun, which mainly includes a gun body, a main valve, a ejector rod, a switch film, a self-sealing rod, a self-control rod, an auxiliary valve seat, an auxiliary valve, an oil nozzle, a switch handle, etc. Structure, in which the switch handle bears on the ejector rod of the main valve, the auxiliary valve extends through the air pipe to the outlet end of the oil outlet pipe and communicates with the atmosphere, and the self-sealing rod is hinged with the switch handle. The principle is summa...

Problems solved by technology

[0003] According to the above structural principles, after each refueling, there is still a small amount of gasoline (or diesel) in the nozzle of the oil gun. When the staff moves the oil gun from the fuel tank of the car to the fuel dispenser in the station, the small amount of gasoline It will remain at the mouth of the fuel tank, the ground or the oil outlet of the oil gun. Because gasoline is highly volatile, it will be mixed with the air in the gas station. Breathing the mixed oil air for a long time will cause irreversible lesions to the body, and there is also a natural risk of exposure to open flames. Hidden danger
