Described slider tail is cylinder, and spring endoporus is connected with slider tail, and slide block groove is lower narrow wide triangular cross-sectional configuration.
Transmission in flakes head is cylindrical, and transmission in flakes afterbody is semicircle cylindricality.
End cap comprises the top arc shell being connected, conical sealed tube, and conical sealed tube coordinates with the endoporus of pipe body.The remaining dead angle of arc shell structure decrease oil plant, adopts conical sealed tube, strengthens leak tightness.
The external end of pipe is provided with negative thread, and negative thread is connected with fuel oil gun head outside thread.
When use, obturator of the present invention is installed on existing nozzle muzzle by screw thread, in the time that nozzle is worked, oiling work starts to make, and oil plant pressure increases, and washes the lid of end cap open, end cap swings around adapter shaft, and then in flakes the swing of end cap is changed into transmission straight-line motion in flakes by transmission, and promote driving block along the inside motion compresses spring of hollow elongated slot inwall, carry out oiling work; After oiling finishes, spring promotes driving block and moves ahead along hollow elongated slot inwall, and driving block promotes transmission in flakes and then drives end cap lid to swing, by tightly sealing of nozzle outlet, residual oil plant is sealed up for safekeeping in nozzle muzzle outlet, until refueling process next time.After installation, according to the operating mode under different demands, the stiffness factor of regulating spring, guarantees normally to open and seal.
Beneficial effect of the present invention:
1. avoided existing nozzle in each refueling process, remain in the oil plant causing on nozzle inwall because of oil plant and trickle down, reduced waste, also reduced the environmental pollution that oil plant is residual and volatilization causes, increased and refueled on-the-spot safety.
2. adopt machine design, on original Refuel structure basis, improve, simple in structure, use reliably, the potential safety hazard of having avoided electromagnetic component to bring, changes littlely to original nozzle, be convenient to fast large-scale popularization comprehensively.
