Abstract
The utility model relates to a plug of a double-fuel fuel pump. The plug of the double-fuel fuel pump comprises a plug body. A first fuel channel and a second fuel channel are placed inside the plug body at intervals. A spring, a steel ball, gaskets, seal rings and fuel seals are placed inside the first fuel channel. The fuel seals are placed on end mouth of the first fuel channel. The seal rings are placed on the end surfaces of the fuel seals. The gaskets are connected on the seal rings. One end of the spring is connected on the steel ball. The other end of the spring is connected on the inner end surface of the first fuel channel. When the spring releases, the steel ball is tightly connected with the seal rings. The inner structure of the first fuel channel is the same of that of the second fuel channel. When the plug is connected on a connector, the steel ball is pushed up by the connector. The steel ball is departed from the gaskets, the spring is compressed, the connector is tightly connected with the plug, and two seal spaces are formed by the seal rings and the fuel seals. Different fuel is put into two fuel channels and flows into the connector and the aim that two kinds of fuel are sucked is achieved. The double-fuel fuel pump is simple in structure, good in tightness and low in construction cost.
Description
Technical field
The utility model relates to the dependency structure of the fuel supply system of motor, relates in particular to a kind of plug that two kinds of different fuels is supplied to the double fuel fuel pump of motor use.
Background technique
According to Chinese patent application, application number is 201210032137.6, denomination of invention is that a kind of Dual-fuel outboard machine is learnt, Dual-fuel outboard machine uses gasoline when startup and idling, use kerosene during normal operation, the price of the cost ratio gasoline of kerosene is much lower, therefore can reduce greatly the operating cost of outboard machine, and therefore a kind of plug that two kinds of different fuels can be supplied to the double fuel fuel pump of Dual-fuel outboard machine motor use is provided.
The plug of known fuel pump only has single fuel gallery, can only carry a kind of fuel, and the poor sealing of fuel pump plug own, complex structure, and installation cost is high.
The model utility content
The utility model purpose is to provide a kind of simple in structure in order to overcome the deficiencies in the prior art, and good seal performance can be supplied to two kinds of different fuels the plug of the double fuel fuel pump that motor uses.
For achieving the above object, the technical solution adopted in the utility model is: a kind of plug of double fuel fuel pump, comprise header body, and isolation is provided with the first fuel channel, the second fuel channel in the described header body; Be provided with spring, steel ball, pad, seal ring and oil sealing in described the first fuel channel; Described oil sealing is arranged on the port of the first fuel channel, and described seal ring is arranged on the oil sealing interior edge face, and described pad is connected on the seal ring, and described spring one end is connected on the steel ball, and the other end is connected on the first fuel channel interior edge face; When spring is under the releasing state, steel ball closely is connected with seal ring; Described the second fuel channel forms identical with the first fuel channel internal structure.
Preferably, also comprise torsion spring, spanner, snap rivet, described torsion spring is arranged between spanner and the header body, and snap rivet is connected in the torsion spring.
Preferably, described seal ring is O-ring seals.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
The plug of a kind of double fuel fuel pump of the utility model scheme, when plug was linked into joint, steel ball was backed down by joint, steel ball breaks away from pad, spring is compressed, and joint and plug are combined closely, and seal ring and oil sealing have formed the space of two sealings, two fuel galleries pass into respectively different fuel, flow into joint, thereby reach the purpose that sucks two kinds of fuel, simple in structure, and good seal performance, cost is low.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of the plug of a kind of double fuel fuel pump of the present utility model;
Accompanying drawing 2 is that the A-A of plug of a kind of double fuel fuel pump of the present utility model is to sectional view;
