Detailed description of the invention
Below in conjunction with accompanying drawing with specific embodiment to being originally further described, see Fig. 1-Fig. 3;
The self-sealing refueling gun with petroleum vapor recovery and pressure relief that the present embodiment provides, this self-sealing refueling gun also has methanol tolerant, low temperature resistant characteristic.It comprises rifle body 1, main valve 2, push rod 3, spool 4, second stage clip 5 and support 6.In described rifle body 1, have filling passage 7, oil input channel 8 and main valve chamber 9, described oil input channel 8 is connected with filling passage 7 mutually by main valve chamber 9, and it forms the runner on rifle body of fuel oil.Rifle body 1 is positioned at main valve chamber 9 and forms valve seat 10 with the adjoiner of filling passage 7.Main valve 2 comprises flap 11, first stage clip 12 and packing seal 13, packing seal 13 is arranged on flap 11, one end of first stage clip 12 is against on flap 11, the other end of the first stage clip 12 is against on the roof 14 of main valve chamber 9, makes flap 11 be pressed on valve seat 10 by the first stage clip 12, and flap 11 is formed by packing seal 13 and valve seat 10 and is sealed and matched, that is, flap 11 is pressed on packing seal 13, then packing seal 13 is pressed on valve seat 10, this main valve 2 is formed with valve seat 10 and is sealed and matched.Push rod 3 withstands on main valve 2 times, and push up from valve seat 10 by the push rod 3 lifted by main valve 2, push rod 3 matches with handle assembly 15, and this belongs to prior art, repeats no more here.Formed by head 16 and body portion 17 at described spool 4, head 16 is provided with seal ring 18.Flap 11 is provided with host cavity 19 and through hole 20, through hole 20 is connected with host cavity 19, and the body portion 17 of spool 4 is through this through hole 20, and spool 4 and flap 11 form bearing fit, head 16 is received in host cavity 19, and this host cavity 19 should have the space moved axially for head 16.One end of second stage clip 5 is against on flap 11, the other end of the second stage clip 5 is against on support 6, this support 6 is arranged on the end of spool 4, makes head 16 be pressed on the chamber wall of host cavity 19 by the second stage clip 5, and head 16 is formed by seal ring 18 and flap 11 and is sealed and matched.Flap 11 is provided with pressure relief vent 21, specifically, as shown in FIG., this pressure relief vent 21 is facing to head 16, liquid in oil input channel 8 is guided on head 16 by pressure relief vent 21, makes the fluid pressure in oil input channel act on head 16, by this fluid pressure, spool 4 is moved to push rod 3 direction.When oil-feed lead to interior pressure comparatively large and the resistance of stage clip can also be overcome time, oil-feed leads to that interior pressure is more usual to stop rifle in oiling and formed instantaneously, now pressure is larger, destructiveness can be formed, fluid pressure acts on head, spool moves to push rod direction, and the liquid in oil inlet passage is entered in host cavity, thus reaches the object that the pipeline leading to side to oil-feed carries out release.
In the present embodiment, described host cavity 19 is provided with conical surface portion 22, the internal diameter in this conical surface portion 22 is outer little interior large shape.This conical surface portion 22 offsets for the head 16 of spool 4, and the head 16 of spool is formed by seal ring 18 and this conical surface portion 22 and is sealed and matched.Adopt this structure, when release, head and conical surface portion depart to be sealed and matched, and liquid enters host cavity from its gap therebetween.
On the basis of said structure, the self-sealing refueling gun with petroleum vapor recovery and pressure relief can also be provided with flap bracket 23 and top briquetting 24.Described flap bracket 23 is fixedly connected with flap 11, described packing seal 13 is clipped between flap bracket 23 and flap 11, described flap bracket 23 is provided with the counter sink 25 be connected with host cavity, described top briquetting 24 withstands on the upper wall 26 of counter sink 25, described push rod 3 realizes top by this top briquetting 24, flap bracket 23 and is pressed on main valve 2, the opposite face pushing up briquetting 24 and flap bracket 23 is formed with sluice way 27, one end of this sluice way 27 is connected with counter sink 25, and the other end of this sluice way 27 is connected with filling passage 7.Adopt this structure, avoid push rod immediate roof on packing seal, extend the service life of packing seal, effectively can prevent leakage of oil.
As shown in FIG., sluice way 27 is formed by the gap between flap bracket 23 and top briquetting 24, top briquetting 24 top be an inclined-plane 24a, only local edge and flap bracket 23 offset to make to push up the top of briquetting 24, the top remainder of top briquetting 24 and flap bracket 23 form gap and push up briquetting 24 and form free-running fit with the counter sink 25 of flap bracket, and this two-part gap defines sluice way.Certainly, sluice way can also adopt other structure, such as, on the surface of top briquetting, be processed with groove.By this groove, liquid is guided in filling passage.
In the present embodiment, support is formed by collar, and this collar is connected on spool.
Above-described embodiment is only preferred embodiment originally, not limits this protection domain according to this, therefore: the equivalence change that the structure of Fan Yiben, shape, principle are done, all should be covered by within protection domain originally.
