Background technique
According to one Chinese patent application; Application number is 201210032137.6, and denomination of invention is that a kind of double fuel outboard machine is learnt, the double fuel outboard machine uses gasoline when startup and idling; Use kerosene during normal the operation; The price of kerosene is more much lower than the price of gasoline, therefore can reduce the operating cost of outboard machine greatly, therefore a kind of joint that above two kinds of fuel can be provided in the fuel supply device that is installed in need be provided.Fuel joint in the prior art only has single fuel gallery, can not realize the function that two kinds of fuel are supplied with simultaneously, and a little less than the fuel joint sealing performance of existing technology, and complex structure, installation cost is higher.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of simple in structure, good airproof performance, and can realize the double fuel joint that two kinds of fuel are supplied with simultaneously.
Technical solution of the present invention is achieved in that a kind of double fuel joint, comprises joint body, in the said joint body at interval be provided with first fuel channel, second fuel channel; Be provided with end socket, seal ring, movable mandrel, pressure spring in said first fuel channel; Be provided with through hole in the said end socket, an end of end socket connects in first fuel channel, and the other end stretches out; Said end socket stretches out to hold and is provided with the side opening that radially communicates; Said side opening is connected with through hole; Said seal ring is arranged in the end socket; Said movable mandrel is provided with push rod, and said push rod passes through hole and stretches out; Said pressure spring one end is connected on the first fuel channel interior edge face, and the other end is connected on the movable mandrel; When pressure spring discharged, the slide core axial end closely contacted with said seal ring; Said first fuel channel is formed identical with the internal structure of second fuel channel.
Preferably, said movable mandrel and said seal ring surface of contact are slope.
Preferably, also be provided with thimble on the said joint body, said thimble is provided with groove.
Preferably, said seal ring adopts O-ring seals.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
A kind of double fuel joint of the present invention, when the joint cut-in operation, push rod promotion activity mandrel, the slide core axial end is left seal ring, the stressed contraction of pressure spring, the fuel oil via through holes flows into oil pipe after flowing into fuel channel; When inoperative, pressure spring pressure discharges, and the tight Contact Seal ring of slide core axial end forms sealing, thereby realizes that two kinds of fuel supply with simultaneously, and is simple in structure, and good airproof performance, and cost is low.
