Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1, including valve pocket 1 of draining the oil, valve rod 2 of draining the oil, fuel outlet valve spring 3, spool 4 of draining the oil, back-up ring 5, valve seat 6 of draining the oil, Sealing shield ring 7, pole socket 8 of draining the oil, bar 9 of draining the oil, bulb 10, pad 11, filter screen the 12, first sealing ring 13, adjusting nut 14, spool oil return opening the 15, second sealing ring B1, the 3rd sealing ring B2, the 4th sealing ring B3, hexagon thin nut B4, elastic cylindrical pin B5, fastening screw nut B6 etc..
As shown in Figure 1, the present invention is a kind of fuel outlet valve structure, including valve seat 6 of draining the oil, the inner hole of valve seat 6 of draining the oil is arranged drains the oil spool 4, the sheathed valve pocket 1 of draining the oil in valve seat 6 top of draining the oil, and valve rod 2 of draining the oil is connected in spool 4 upper end of draining the oil, and draining the oil spool 4 and the junction of valve rod 2 of draining the oil arranges fuel outlet valve spring 3, described fuel outlet valve spring 3 bottom holds out against in valve seat 6 upper surface of draining the oil, and fuel outlet valve spring 3 upper end holds out against on pad 11, and described pad 11 is sheathed on drains the oil on valve rod 2；Valve seat 6 bottom of draining the oil is provided with radial direction through hole, is respectively provided with filter screen 12 at the two ends of radial direction through hole；Drain the oil valve pocket 1 lower end and drain the oil Sealing shield ring the 7, the 4th sealing ring B3 is set between valve seat 6；The sheathed pole socket 8 of draining the oil in described valve pocket 1 circumferential surface top of draining the oil, pole socket 8 of draining the oil is fixed by hexagon thin nut B4 axial limiting, and the link of pole socket 8 of draining the oil connects bar 9 of draining the oil, the operating side connecting ball head 10 of bar 9 of draining the oil by elastic cylindrical pin B5；Drain the oil valve pocket 1 surface configuration the second sealing ring B1.
Drain the oil valve rod 2 upper end from the bottom up successively threaded adjusting nut 14, fastening screw nut B6.
Drain the oil on valve seat 6, the 3rd sealing ring B2, back-up ring 5 are set corresponding to the lower end of filter screen 12.
Draining the oil and offer spool oil return opening 15 on spool 4, its upper and lower side has two seals circle with fuel outlet valve set junction.
