Fig. 2 is the structure enlarged drawing at A place in Fig. 1.
Fig. 3 is this flap bracket and the assembling schematic diagram of top briquetting.
The specific embodiment
Below in conjunction with accompanying drawing with specific embodiment to being originally further described, referring to Fig. 1-Fig. 3;
What the present embodiment provided reclaims and the white envelope nozzle of pressure relief with oil gas, and this white envelope nozzle also has resistance to methyl alcohol, low temperature resistant characteristic.It comprises rifle body 1, main valve 2, push rod 3, spool 4, the 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.On rifle body 1, be positioned at main valve chamber 9 and form valve seat 10 with the adjoiner of filling passage 7.Main valve 2 comprises flap 11, the first stage clip 12 and packing seal 13, packing seal 13 is arranged on flap 11, one end of the 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, by the first stage clip 12, flap 11 is pressed on valve seat 10, and flap 11 is formed and is sealed and matched with valve seat 10 by packing seal 13, that is to say, flap 11 is pressed on packing seal 13, and packing seal 13 is pressed on valve seat 10, makes this main valve 2 form and be sealed and matched with valve seat 10.Push rod 3 withstands on main valve 2 times, by the push rod 3 lifting, main valve 2 is pushed up from valve seat 10, and push rod 3 matches with handle assembly 15, and this belongs to prior art, repeats no more here.At described spool 4, by head 16 and body portion 17, formed, seal ring 18 is installed on head 16.On flap 11, be provided with host cavity 19 and through hole 20, through hole 20 and host cavity 19 are connected, and the body portion 17 of spool 4 is through this through hole 20, and spool 4 forms bearing fit with flap 11, head 16 is received in host cavity 19, and this host cavity 19 should have for the axially movable space of head 16.One end of the 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, by the second stage clip 5, head 16 is pressed on the chamber wall of host cavity 19, and head 16 is formed and is sealed and matched with flap 11 by seal ring 18.On flap 11, be provided with pressure relief vent 21, specifically, as shown in FIG., this pressure relief vent 21 is facing to protuberance 16, pressure relief vent 21 is guided to the liquid in oil input channel 8 on protuberance 16, and the fluid pressure in oil input channel is acted on protuberance 16, by this fluid pressure, spool 4 is moved to push rod 3 directions.When the pressure in oil-feed is logical greatly also can also overcome the resistance of stage clip, pressure in oil-feed is logical stops rifle moment formation in oiling more conventionally, now pressure is larger, can form destructiveness, fluid pressure acts on protuberance, spool moves to push rod direction, and the liquid in oil inlet passage is entered in host cavity, thereby reaches the object that the pipeline of the logical side of oil-feed is carried out to release.
In the present embodiment, on described host cavity 19, be provided with conical surface portion 22, the internal diameter of 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 and is sealed and matched with this conical surface portion 22 by seal ring 18.Adopt this structure, when release, protuberance and conical surface portion depart to be sealed and matched, and from it, the gap between the two enters host cavity to liquid.
On the basis of said structure, with oil gas, reclaim and the white envelope nozzle of 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, on described flap bracket 23, be provided with the counter sink 25 being connected with host cavity, described top briquetting 24 withstands on the upper wall 26 of counter sink 25, described push rod 3 is realized top and is pressed on main valve 2 by this top briquetting 24, flap bracket 23, on the opposite face of top briquetting 24 and flap bracket 23, be 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, avoided push rod immediate roof on packing seal, extended the service life of packing seal, can effectively prevent leakage of oil.
As shown in FIG., sluice way 27 is formed by the gap between flap bracket 23 and top briquetting 24, at the top of top briquetting 24, be an inclined-plane 24a, the top that makes top briquetting 24 only local edge and flap bracket 23 offsets, jacking block presses 24 top remainder and flap bracket 23 forms gap and top briquetting 24 forms free-running fit with the counter sink 25 of flap bracket, and this two-part gap has formed sluice way.Certainly, sluice way can also adopt other structure, for example, 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 this preferred embodiment, not limits according to this this protection domain, therefore: the equivalence that the structure of Fan Yiben, shape, principle are done changes, within all should being covered by this protection domain.
