Abstract
A kind of wing tank fuel cock, including housing, valve element, handle, seal assembly and valve core shaft, housing is arranged between fuselage fuel cell and wing tank, housing left end pipe portion is connected right-hand member pipe portion and is connected with wing tank pipe with fuselage fuel cell pipe, valve core shaft one end passes perpendicularly through housing other end insertion inner walls and forms flexible connection, valve element is fixedly mounted on valve core shaft by screw and is located at enclosure interior, handle is arranged on the exposed junction of valve core shaft, and seal assembly is arranged between handle and housing.The present invention is compared to background technology advantageously：Fuel cock contour dimension and Weight control are substantially better than conventional design；Replaceable seal easy to wear in situ, effectively realizes the function that wing tank and fuselage fuel cell separately refuel.And the fuel cock simple structure, easy to operate, reliable operation.
Description
Technical field
The present invention relates to aircraft fuel system technical field, more particularly to a kind of wing tank fuel cock.
Background technology
Fuel cock is set by wing tank filling conduit, wing tank can be selected to refuel, and then realize that aircraft pre-selection is refueled, be applied in polytypic aircraft.Electronic board plug type or Manual turning plate type being used fuel cock, fuel cock appearance and size is corresponding with latus rectum, and the switch can be pulled down after long-term use to carry out overhauling maintenance more.But for some light aerocrafts, installing space is nervous at this, board plug type or turnover plate type switch can not meet installation requirement, and fuel cock seal has wear problem, it is impossible to abrasive element is repaired using using maintenance mode of offing normal.
The content of the invention
It is an object of the invention to provide aircraft fuel system wing fuel cock Miniaturization Design, fuel cock seal original position maintenance issues easy to wear are solved.
A kind of wing tank fuel cock, including housing, valve element, handle, seal assembly and valve core shaft, housing is arranged between fuselage fuel cell and wing tank, housing left end pipe portion is connected right-hand member pipe portion and is connected with wing tank pipe with fuselage fuel cell pipe, valve core shaft one end passes perpendicularly through housing other end insertion inner walls and forms flexible connection, valve element is fixedly mounted on valve core shaft by screw and is located at enclosure interior, handle is arranged on the exposed junction of valve core shaft, and seal assembly is arranged between handle and housing.
Further, the wing tank fuel cock also includes tabular valve, and tabular valve is arranged between housing right-hand member pipe portion and wing tank pipe.
The present invention is compared to background technology advantageously：Fuel cock contour dimension and Weight control are substantially better than conventional design；Replaceable seal easy to wear in situ, effectively realizes the function that wing tank and fuselage fuel cell separately refuel.And the fuel cock simple structure, easy to operate, reliable operation.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
In figure, 1, housing；2nd, valve element；3rd, tabular valve；4th, handle；5 seal assemblies；6th, valve core shaft.
Specific embodiment
Principle of the invention and feature are described below in conjunction with accompanying drawing, example is served only for explaining invention, is not intended to limit the scope of the present invention.
A kind of wing tank fuel cock, including housing 1, valve element 2, handle 4, seal assembly 5 and valve core shaft 6, housing 1 is arranged between fuselage fuel cell and wing tank, the left end pipe portion of housing 1 is connected right-hand member pipe portion and is connected with wing tank pipe with fuselage fuel cell pipe, the one end of valve core shaft 6 passes perpendicularly through the other end of housing 1 insertion housing 1 inwall and forms flexible connection, valve element 2 is fixedly mounted on valve core shaft 6 and is located inside housing 1 by screw, handle 4 is arranged on the exposed junction of valve core shaft 6, and seal assembly 5 is arranged between handle 4 and housing 1.
To make the wing tank fuel oil in aircraft flight not blow back into fuselage fuel cell, it is ensured that oil transportation order, flight safety is ensured, the wing tank fuel cock also includes tabular valve 3, and tabular valve 3 is arranged between the right-hand member pipe portion of housing 1 and wing tank pipe.
Operation principle of the invention is, when selection is only refueled to fuselage fuel cell, to stir valve core shaft 6 by handle 4 and rotate, and valve core shaft 6 is with the passage between the rotary closing fuselage fuel cell of movable valve plug 2 and wing tank；If desired for from fuselage fuel cell toward wing tank refuel when, then valve core shaft 6 can be stirred by handle 4 and rotated, valve core shaft 6 is with the passage between the Unscrew fuselage fuel cell of movable valve plug 2 and wing tank.Reach the purpose individually refueled between fuselage fuel cell and wing tank.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, and those skilled in the art's some that to be made to some of which part variations embody principle of the invention, belong within protection scope of the present invention.
