The invention discloses an oil gun interface, which aims to reduce the phenomenon that high-speed liquid flow directly impacts a liquid level so that a large amount of gas is involved in the oil level to generate a large amount of foam, and the specific scheme is as follows: an oil gun interface comprises a connecting joint, a rotary impeller and a dispersing frame, wherein the dispersing frame is a hollow support frame, and a bottom support is arranged at the center of the bottom of the dispersing frame; the connecting joint is connected with the top of the dispersing frame, the top support is arranged at the center of the dispersing frame, two ends of the rotary impeller are respectively arranged between the bottom support and the top support and can freely rotate around an axis, so that high-speed kinetic energy of liquid flow can be converted into the rotary kinetic energy of the impeller, the flow velocity of the liquid flow finally impacting the oil surface is greatly reduced, and the generation of foams is greatly reduced.
Description
Technical Field
The invention relates to a nozzle of a fuel gun, in particular to a device capable of reducing foam generated by splashing of the fuel gun in the fuel filling process so as to improve the fuel filling efficiency.
Background
The vehicle of present filling station refuels all adopts and from the open mode of refueling of oil tank nozzle from the oil filling gun, along with the improvement of filling speed, refuel in-process because high-speed liquid stream directly strikes the liquid level, thereby can produce the foam of oil-gas mixture, constantly increase as the foam, will make and from the automatic rifle of jumping of the oil filling gun misunderstanding that the oil tank has been filled, cause and need to break off the refueling process, wait to open the nozzle again after the foam breaks out gradually, especially to the large capacity oil tank, this process need relapse many times sometimes, thereby influence refuel efficiency, current solution usually starts from the nozzle, through the improvement in aspects such as length of nozzle filler tube, avoid producing too much foam.
Disclosure of Invention
The invention aims to provide a fuel nozzle interface, which adopts a method for converting energy into rotational energy in order to reduce the phenomenon that high-speed liquid flow directly impacts a liquid level so that a large amount of gas is involved in the oil level to generate a large amount of foam, and the specific scheme is as follows: an oil gun interface comprises a connecting joint, a rotary impeller and a dispersing frame, wherein the dispersing frame is a hollow support frame, and a bottom support is arranged at the center of the bottom of the dispersing frame; the connecting joint is connected with the top of the dispersing frame, the top support is arranged at the center of the dispersing frame, two ends of the rotary impeller are respectively arranged between the bottom support and the top support and can freely rotate around an axis, so that high-speed kinetic energy of liquid flow can be converted into the rotary kinetic energy of the impeller, the flow velocity of the liquid flow finally impacting the oil surface is greatly reduced, and the generation of foams is greatly reduced.
In order to obtain better damping effect, the impeller adopts an open-type blade impeller; in order to fully utilize the space and the inner wall of the oil tank, the impeller adopts a spiral centrifugal impeller.
On the basis, in order to increase the rotation resistance and additionally increase the elastic resistance, a stretchable spring can be arranged between the impeller and the top support, so that the impeller can move towards the top end according to the different stresses of the impeller, or a compressible spring can be arranged between the impeller and the bottom support, so that the impeller can move towards the top end according to the different stresses of the impeller.
