The specific embodiment
A kind of aviation pressure oiling joint as shown in Figure 1, comprise fittings body 1, pressure maintaining valve 2, filter screen seat 3, rubber hose coupling 4 and butt joint handle 5, fittings body 1, pressure maintaining valve 2, filter screen seat 3 and rubber hose coupling 4 are connected to each other, butt joint handle 5 is arranged on the fittings body 1, rubber hose coupling 4 is used for being connected with the sebific duct of carrying oil plant, oil plant in the sebific duct enters aviation pressure oiling joint by rubber hose coupling 4, the impurity that oil plant at first filters wherein by filter screen seat 3, enter pressure maintaining valve 2 then, the effect of pressure maintaining valve 2 is to guarantee that the oil pressure in the fuel tank within the limits prescribed when refueling, in case surpass this pressure, pressure maintaining valve 2 cuts off oil transportation channel with SELF CL.Fittings body 1 docks with the oil filling port of aircraft, will send into fuel tanker from the oil plant that pressure maintaining valve 2 is come, and between fittings body 1 and the pressure maintaining valve 2, and the connection structure between pressure maintaining valve 2 and the filter screen seat 3 is the rotatable sealing connection structure.This rotatable sealing connection structure comprises fittings body 1 and pressure maintaining valve 2, and pressure maintaining valve 2 and filter screen seat 3 play the steel ball 8 of interconnect functions in the raceway 6 on the joint face and seal ring 7, the raceway 6 each other and the filler opening 9 of filling steel ball 8 and the screw plug 10 of obstruction filler opening 9 to raceway 6 in.
Shown in Fig. 2,3, add oil valve handgrip 1-5 control eccentric shaft 1-6 and rotate, eccentric shaft 1-6 moves up and down in connecting rod base 1-9 by link rod plate 1-7 drivening rod 1-8, and moving up and down of connecting rod 1-8 promotes valve 1-3 opening and closing.
During butt joint, draw-in groove 11 on butt plate 1-1 and the valve base 1-2 is aligned with each other, and during butt joint, the draw-in groove 11 of flange by butt plate 1-1 that adds on the font of aircraft is inserted in the draw-in groove 11 of valve base 1-2, valve base 1-2 and fittings body 1-1 can relatively rotate, and butt plate 1-1 is fixed on the fittings body 1.When gripping butt joint handle 5 these aviation pressure oiling joints of rotation, the draw-in groove 11 of butt plate 1-1 and the draw-in groove 11 of valve base 1-2 stagger mutually, the non-draw-in groove of butt plate 1-1 partly makes the flange that adds on the font of aircraft deviate from, and that realizes fittings body 1 and aircraft adds docking of font.When butt joint was finished, valve safety screen 1-4 removed from original position, and the motion of link rod plate 1-7 is no longer kept out at the top of valve safety screen 1-4, link rod plate 1-7 can free motion, break off with the fingers and thumb and add oil valve handgrip 1-5, add oil valve handgrip 1-5 and drive eccentric shaft 1-6 rotation, open valve 1-3.When aviation pressure oiling joint is in fueling state, valve 1-3 is in and moves down open mode, the link rod plate 1-7 of this moment has blocked the sidepiece of valve safety screen 1-4, because valve safety screen 1-4 and valve base 1-2 fix, valve base 1-2 can't be rotated when fueling state, also just cannot the font that add of this aviation pressure oiling joint and aircraft be broken away from by rotation.Close valve 1-3, link rod plate 1-7 return, disengaging is spacing to the sidepiece of valve safety screen 1-4, rotate aviation pressure oiling joint, valve safety screen 1-4 moves, and when aviation pressure oiling joint and the disengaging of aircraft refuelling seat, the end face of valve safety screen 1-4 blocks link rod plate 1-7 again, realization is to the locking of valve 1-3, and valve 1-3 can't open.
The connection structure of filter screen seat 3 and rubber hose coupling 4 comprises the flange 3-1 on the filter screen seat 3, be enclosed within the limit coil 3-2 that only can move up and down on the filter screen seat 3, wave mode elastic ring 3-3 that promotion limit coil 3-2 moves and flange locked groove 4-1 and the flange embedded groove 4-2 in the rubber hose coupling 4, has the spacing push rod 3-4 that can snap in flange embedded groove 4-2 on the limit coil 3-2, the flange 3-1 that screws in flange locked groove 4-1 by flange embedded groove 4-2 connects filter screen seat 3 and rubber hose coupling 4, embeds the spacing push rod 3-4 locking rubber hose coupling 4 of flange embedded groove 4-2 under the pushing and pressing of wave mode elastic ring 3-3.With the flange 3-1 on the flange embedded groove 4-2 aligning filter screen seat 3 of rubber hose coupling 4, press down rubber hose coupling 4, rubber hose coupling 4 promotes limit coil 3-2 and descends, pressing down the back that puts in place makes flange embed flange locked groove 4-1 by rotation rubber hose coupling 4, continuing the spacing push rod 3-4 of rotation on limit coil 3-2 embeds the flange embedded groove 4-2 of rubber hose coupling 4 and rubber hose coupling 4 is realized locking, depress limit coil 3-2, releasing is spacing to rubber hose coupling 4, rotate rubber hose coupling 4 and from flange embedded groove 4-2, deviate from, promptly realize 3 release of rubber hose coupling 4 and filter screen seat until flange.
This aviation pressure oiling joint also has a series of fender guards and comprises sheath 12, protecting cover 13, electrostatic conductor assembly 14.
