Abstract
The utility model discloses a fuel gun body. The key point of the technical scheme is that the fuel gun body comprises a casing, as well as a fuel inlet chamber, a main valve chamber, an auxiliary valve chamber and a fuel outlet chamber all communicated with one another and arranged inside the casing, wherein a first dense mesh used for filtering impurity is arranged at the communicating part of the fuel inlet chamber and the main valve chamber; the shape and the size of the communicating part of the fuel inlet chamber and the main valve chamber are matched with those of the first dense mesh. The first dense mesh is adopted to prevent the impurity from entering the main valve chamber from the fuel inlet chamber, so that the problem that the main valve or the casing is worn due to the impurity which is clamped at the contact position of the main valve and the casing is solved, the main valve and the casing can be effectively sealed, and the service life of the fuel gun is prolonged.
Description
Technical field
The utility model relates to the nozzle field, and more particularly, it relates to a kind of fuel oil gun body.
Background technology
Self-sealing series nozzle is suitable for the filling operation of the lightweight oils such as kerosene, gasoline, diesel oil.The self-packer of body of a gun design can be guaranteed when container is filled it up with, automatically to close oil gun, prevents that medium is excessive.
Self-sealing refueling gun is mainly by rifle body, main valve, push rod, switch membrane, push rod, form from control lever, auxiliary valve core, gun adapter etc.And in the rifle body, comprise housing and be placed in enclosure interior and the oil suction chamber, main valve chamber, the secondary valve chamber that connect of conducting and go out oil pocket successively, main valve chamber comprises and being wholely set and main valve body installation portion and the push rod installation portion of conducting; Secondary valve chamber comprises and being wholely set and the auxiliary valve body installation portion of conducting and from the control lever installation portion.
Each chamber of traditional enclosure interior is all that direct conducting connects, and more or less all can there be some impurity in the lightweight oils such as kerosene, gasoline, diesel oil, when the lightweight oils with impurity flows into main valve chamber from oil suction chamber, the contact site of the easy clamping stagnation of impurity between main valve and housing, thereby main valve or housing can produce wearing and tearing, affect the leak tightness between main valve and housing, nozzle is not high service life.
The utility model content
Deficiency for the prior art existence, the purpose of this utility model is to provide a kind of fuel oil gun body, this rifle physical efficiency avoids causing because of the contact site of impurity clamping stagnation between main valve and housing the problem of main valve or shell wearing and tearing, making between main valve and housing can effective sealing, extends nozzle service life.
For achieving the above object, the utility model provides following technical scheme: a kind of fuel oil gun body, comprise housing and be placed in enclosure interior and the oil suction chamber, main valve chamber, the secondary valve chamber that connect of conducting and go out oil pocket successively, described oil suction chamber and main valve chamber conducting place are provided with the first close net that can be used for impurity screening, and the shape size of described oil suction chamber and main valve chamber conducting place between the two and the shape size of the first close net are complementary.
By adopting technique scheme, adopt the first close net to stop that impurity enters main valve chamber by oil suction chamber, avoid causing because of the contact site of impurity clamping stagnation between main valve and housing the problem of main valve or shell wearing and tearing, making between main valve and housing can effective sealing, extends nozzle service life.
The utility model further is set to: described main valve chamber and conducting place of secondary valve chamber are provided with the second close net, and the shape size of described main valve chamber and secondary valve chamber conducting place between the two and the shape size of the second close net are complementary.
By adopting technique scheme, set up the second close net, prevent from flowing into again secondary valve chamber after partial impurities from flowing into main valve chamber, guarantee the effective sealing of contact site between secondary valve chamber and housing, further help improve the service life of nozzle.
The utility model further is set to: described main valve chamber comprises valve body installation portion and the push rod installation portion that is wholely set also conducting, the other end of the corresponding push rod installation portion of described valve body installation portion forms the opening end with opening, conducting place between the two of oil suction chamber and main valve chamber, main valve chamber and secondary valve chamber between the two conducting place all be placed in the opening end of main valve chamber, the first close net, the second close net all removably connect with housing.
By adopting technique scheme, when the first close net, the second close impurity adhered on the net when too much, the close net that can more renew easily, the service life that further helps improve nozzle.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model fuel oil gun body embodiment.
The specific embodiment
With reference to Fig. 1, the utility model fuel oil gun body embodiment is described further.
A kind of fuel oil gun body, comprise housing 1 and be placed in oil suction chamber 11, main valve chamber 12, the secondary valve chamber 13 of housing 1 inside and conducting connection successively and go out oil pocket 14, described oil suction chamber 11 is provided with main valve chamber 12 conductings place the first close net 2 that can be used for impurity screening, and the shape size of described oil suction chamber 11 and main valve chamber 12 conducting place between the two and the shape size of the first close net 2 are complementary.
By adopting technique scheme, adopt the first close net 2 to stop that impurity enters main valve chamber 12 by oil suction chamber 11, avoid causing because of the contact site of impurity clamping stagnation between main valve and housing 1 problem of main valve or shell wearing and tearing, making between main valve and housing 1 can effective sealing, extends nozzle service life.
Described main valve chamber 12 is provided with the second close net 3 with secondary valve chamber 13 conductings place, and the shape size of described main valve chamber 12 and secondary valve chamber 13 conducting place between the two and the shape size of the second close net 3 are complementary.
By adopting technique scheme, set up the second close net 3, prevent from flowing into again secondary valve chamber 13 after partial impurities from flowing into main valve chamber 12, guarantee the effective sealing of contact site between secondary valve chamber 13 and housing 1, the service life that further helps improve nozzle.
Described main valve chamber 12 comprises valve body installation portion 121 and the push rod installation portion 122 that is wholely set also conducting, the other end of the corresponding push rod installation portion 122 of described valve body installation portion 121 forms the opening end 1211 with opening, oil suction chamber 11 and main valve chamber 12 conducting place between the two, main valve chamber 12 and the secondary valve chamber 13 close net 3 of the close net 2, second of opening end 1211, the first that conducting place all is placed in main valve chamber 12 between the two all removably connects with housing 1.
By adopting technique scheme, when the impurity adhered on the close net 3 of the first close net 2, second is too much, the close net that can more renew easily, the service life that further helps improve nozzle.
