Preferably, spring is equipped with close to import oil pipe outer cover described in the end of outlet oil pipe.
The beneficial effects of the utility model：A kind of oil drip-preventing list main valve refueling nozzle gun barrel described in the utility model, when adding
When oil gun is hung on fuel charger, by gravity close to annular magnet valve seat, annular magnet valve seat is sucked for annular valve plug and gland
Annular valve plug and gland form sealing between gasket seal and annular magnet valve seat；When needing to refuel, refueling nozzle gun barrel to
Under, due to the magneticaction between annular magnet valve seat and annular valve plug and gland, between annular magnet valve seat and gasket seal
Still it realizes sealing, oil dripping can be prevented；When fuel charger operation of oil pump, refueling nozzle gun barrel internal pressure is greater than annular valve plug and pressure
Magnetic force between lid and annular magnet valve seat, is detached from, gun barrel is normally fuel-displaced between annular valve plug and gland and annular magnet valve seat.
List main valve refueling nozzle gun barrel described in the utility model can guarantee that refueling nozzle normally refuels, while after being also avoided that refueling nozzle on-hook
Refueling again, there is a phenomenon where Residual oil water clocks.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment 1：
A kind of oil drip-preventing list main valve refueling nozzle gun barrel, as shown in Fig. 1~2, including import oil pipe 1 and outlet oil pipe 2, import
It is connected through a screw thread between oil pipe 1 and outlet oil pipe 2.The end of import oil pipe 1 described in outlet oil pipe junction is provided with ring
Shape magnetism valve seat 3 is provided with ventilation pipe 4 in import oil pipe 1, is provided with suction pipe 5 in outlet oil pipe 2, suction pipe 5 with
Ventilation pipe 4 connects, and the end of ventilation pipe 4 described in suction pipe junction is provided with annular valve plug 6 and gland 7, presses
Lid 7 is provided with gasket seal 8 by connecting and fixing, and between gland 7 and annular valve plug 6 with annular valve plug 6.In the present embodiment,
