Embodiment
A kind of fuel charger line check valve structure with reverse pressure relief capability of the utility model, it has main valve seat 1, master
Valve element 2 and reversely secondary valve 3；It filters A oil inlets, it can also be arranged on according to demand in the present embodiment accompanying drawing installed in oil
The other positions of fuel charger pipeline, such as fuel charger with the hard link of oiling island flowline, oil filter out entering for mouth or flowmeter
The positions such as mouth, can install one or more, and mounting means can pass through spiral shell using conventional triangle flange form, circular flange formula
Tether and connect, can not also be connected with, relevant position is directly pressed into by step round flange, stepped hole, profile housing is saved.
Used it is of course also possible to be separately provided profile housing formation independent assembly.
The main valve seat 1 tool upper end has oil-out 4, and main valve plug 2 is provided with the bonnet 5 for being used for closing oil-out 4, bonnet 5
Between be vertically provided with the first valve body 6 for accommodating reversely secondary valve；There is fixed part 7, the activity of the first valve body 6 in the middle of main valve seat 1
The fixed part 7 is placed in, fixed part 7 sets the path 8 that fuel feeding passes through, and the lower section of fixed part 7 is oil inlet；The lower section of first valve body 6
Provided with baffle plate 9, the first spring 10 is provided between baffle plate 9 and fixed part 7, first spring 10 is set under the first valve body 6
End；Bonnet 5 is integrally formed with the first valve body 6, and it has the first accommodation space 11 through bonnet 5, and reversely pair valve 3 is placed in this
In first accommodation space 11, first accommodation space 11 connection relief hole 12, relief hole 12 is from the first valve body of side insertion 6.
The reverse secondary valve 3 has the second valve body 13, and the second accommodation space 14 is set in second valve body 13, and this second is housed
The up/down perforation of space 14, top is provided with upper outlet 15, and bottom is provided with lower outlet 16；Reversing valve core is equipped with second valve body 13
17, the reverse one end of valve element 17 passes upper outlet 15, and the other end passes lower outlet 16；Reversely below the adjacent upper outlet 15 of valve element 17
First stop section 18 is set, and the adjacent lower lower section of outlet 16 sets the second stop section 19；Upper outlet 15 is blocked in first stop section 18,
Lower outlet 16 is blocked in second stop section 19, and it can be that area is more than corresponding upper outlet 15 that it, which blocks the implementation accordingly exported,
With lower outlet 16.Also, the lower outlet 16 is in be arranged the second bullet between toe-in structure, the lower stop section 18 of outlet 16 and first
Spring 20, causes second spring not fall out using the structure of the toe-in.
When oil gun is opened, as illustrated in figures 1A and ib, main valve plug 2 is lifted up, and drives bonnet 5 simultaneously upward, bonnet 5
