Summary of the invention
The present invention is directed to the problems referred to above, it is provided that a kind of fuel outlet valve valve body structure, this valve body structure reliable in action, the problem that leakage of oil will not occur.
According to technical scheme: a kind of fuel outlet valve valve body structure, it is characterized in that: include valve seat of draining the oil, the inner hole of valve seat of draining the oil is arranged drains the oil spool, drain the oil the sheathed valve pocket of draining the oil in valve seat top, valve rod of draining the oil is connected in spool upper end of draining the oil, and is draining the oil spool and the junction of valve rod of draining the oil arranges fuel outlet valve spring, and described fuel outlet valve spring bottom end holds out against in valve seat upper surface of draining the oil, fuel outlet valve spring upper end holds out against on pad, and described pad is sheathed on drains the oil on valve rod; Drain the oil on valve seat, the 3rd sealing ring, back-up ring are set corresponding to the lower end of filter screen; Drain the oil valve pocket lower end and drain the oil Sealing shield ring, the 4th sealing ring are set between valve seat; Valve pocket surface configuration of draining the oil the second sealing ring, valve seat bottom of draining the oil is provided with radial direction through hole, is respectively provided with filter screen at the two ends of radial direction through hole.
As a further improvement on the present invention, drain the oil described in valve rod upper end from the bottom up successively threaded adjusting nut, fastening screw nut.
As a further improvement on the present invention, described in drain the oil spool offer spool oil return opening, its upper and lower side has twice the first sealing ring with fuel outlet valve set junction.
The method have technical effect that: product valve body structure of the present invention design is simple, reasonable, operationally, external part and valve body structure cooperate, when operation drained the oil by needs, external part presses valve rod of draining the oil, valve rod of draining the oil press spool of draining the oil descending in valve seat of draining the oil, when the radial direction through hole on valve seat of draining the oil is connected with the opening interval at valve line place, realize both having played the effect of draining the oil, also function to regulate the effect of flow;The spool oil return opening additionally arranged in product of the present invention and multiple sealing ring, effectively realize good sealing effectiveness, it is ensured that the phenomenon of leakage of oil will not occur product in course of action.
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 the 7, second sealing ring 8, the 3rd sealing ring 9, the 4th sealing ring 10, pad 11, filter screen the 12, first sealing ring 13, adjusting nut 14, spool oil return opening 15, fastening screw nut 16 etc.
As shown in Figure 1, the present invention is a kind of fuel outlet valve valve body 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; Drain the oil on valve seat 6, the 3rd sealing ring 9, back-up ring 5 are set corresponding to the lower end of filter screen 12; Drain the oil valve pocket 1 lower end and drain the oil Sealing shield ring the 7, the 4th sealing ring 10 is set between valve seat 6; Drain the oil valve pocket 1 surface configuration the second sealing ring 8; 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 rod 2 upper end from the bottom up successively threaded adjusting nut 14, fastening screw nut 16.
Draining the oil and offer spool oil return opening 15 on spool 4, its upper and lower side has twice the first sealing ring 13 with valve pocket 1 junction of draining the oil.
The work process of the present invention is as follows: product of the present invention is operationally, as requested product of the present invention is installed on corresponding dynamic power machine, operationally external operating parts is arranged at and drains the oil on valve rod 2, when valve body is drained the oil operation by needs, valve rod 2 of draining the oil is pushed down by external piece, spool 4 DL synchronization of draining the oil is driven when valve rod 2 of draining the oil is descending, when the radial direction through hole on valve seat of draining the oil is connected with the opening interval at valve line place, now, product of the present invention can realize operation of draining the oil, the fluid released filters via filter screen 12, valve body is drained the oil after end, resetted by fuel outlet valve spring 3 valve rod 2 of draining the oil, product course of action of the present invention is reliable and stable. product of the present invention has added adjusting nut 14, fastening screw nut 16, by regulating the upper-lower position of adjusting nut 14, external piece pressure is drained the oil after valve rod 2, can regulate and drain the oil spool 4 and the opening at the valve seat 6 valve line place that drains the oil interval, so both play the effect of draining the oil, also function to regulate the effect of flow. so, valve block just need not be processed throttle bore, moreover it is possible to omit a choke valve, save production cost. additionally drain the oil spool 4 and there is two seals circle 13 valve pocket 1 junction of draining the oil, and added individual spool oil return opening 15, effectively prevent outer permeability.
