Abstract
The utility model relates to a double-fuel connector which comprises a connector body. A first fuel channel and a second fuel channel are placed inside the connector body at intervals. A seal head, seal rings, a movable central spindle and a compression spring are placed inside the first fuel channel. A through hole is placed inside the seal head. One end of the through hole is connected inside the first fuel channel and the other end of the through hole extends outwards. The end extending outwards is provided with a side hole communicated with the through hole in a radial direction. A push pole is placed on the movable central spindle, penetrates through the through hole and extends outwards. One end of the compression spring is connected on the inner end surface of the first fuel channel and the other end of the compression spring is connected with the movable central spindle. When the compression spring releases, the end surface of the movable central spindle is tightly contacted with the seal rings. The inner structure of the first fuel channel is the same with that of the second fuel channel. When in operation, the push rod pushes the movable central spindle, the end surface of the movable central spindle is departed from the seal rings, the compression spring is compressed, and the fuel flows into fuel channels and then flows into a fuel pipe, and therefore the double-fuel can be simultaneously supplied. The double-fuel connector is simple in structure, good in tightness and low in construction cost.

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, good airproof performance, and can realize the double fuel joint that two kinds of fuel are supplied with simultaneously.
For achieving the above object, the technical solution adopted in the utility model is: a kind of double fuel joint, comprise joint body, and the interval is provided with the first fuel channel, the second fuel channel in the described joint body; Be provided with end socket, seal ring, movable mandrel, Compress Spring in described the first fuel channel; Be provided with through hole in the described end socket, an end of end socket connects in the first fuel channel, and the other end stretches out; Described end socket stretches out to hold and is provided with the side opening that radially communicates; Described side opening is connected with through hole; Described seal ring is arranged in the end socket; Described movable mandrel is provided with push rod, and described push rod passes through hole and stretches out; Described Compress Spring one end is connected on the first fuel channel interior edge face, and the other end is connected on the movable mandrel; When Compress Spring discharges, slide core axial end and described seal ring close contact; Described the first fuel channel forms identical with the internal structure of the second fuel channel.
Preferably, described movable mandrel and described seal ring surface of contact are slope.
Preferably, also be provided with thimble on the described joint body, described thimble is provided with groove.
Preferably, described seal ring adopts O-ring seals.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of double fuel joint of the utility model scheme, when the joint cut-in operation, push rod promotion activity mandrel, the slide core axial end is left seal ring, the stressed contraction of Compress Spring, the fuel oil via through holes flows into oil pipe after flowing into fuel channel; When inoperative, Compress Spring earth pressure release, slide core axial end close contact seal ring form sealing, thereby realize that two kinds of fuel supply with simultaneously, and be simple in structure, and good airproof performance, and cost is low.
