The specific embodiment
Below in conjunction with accompanying drawing, structural principle of the present utility model and embodiment are done to concrete elaboration:
Oil-gas recovery self-sealing nozzle as shown in Figure 1,15 bottoms, rifle body asphalt channel chamber are integrated independently oil gas recycling cavity 13, forms complete return gas channel by being communicated with Oil-gas Separation assembly 2 and barrel assembly 12, and is separated with fluid passage.The inner integrated oil gas of gun barrel 23 reclaims path 25, tonifying Qi path 28 and fluid output channel 27, as shown in Figures 2 and 3, these three kinds of paths adopt disposable extrusion forming, oil gas recovery path stopper A21 and oil gas recovery path stopper B26 seal respectively the two ends of oil gas recovery approach, the oil gas distributing in refueling process, by 6 oil gas of gun barrel 23 front ends, reclaiming aperture 24 enters in oil gas recovery path 25, pass through again the oil gas recycling cavity 13 of rifle body 1 bottom to the gas channels 53 of Oil-gas Separation assembly 2, thereby realize the function that oil gas reclaims.
Gun barrel 23 inflow points form Venturi effect generating means by auxiliary valve spring 17, secondary valve valve port 19, auxiliary valve spring seat 20, secondary bonnet 18 and gun barrel 23.Tonifying Qi path 28 is connected with the vacuum generation path 11 on rifle body 1 through direction ball 29 and direction seat 30.During nozzle work, oil stream backs down secondary valve bonnet 18, aperture place at secondary valve valve port 19 produces Venturi effect, by the vacuum generation path 11 on rifle body 1, air by vacuum in the diaphragm 32 top cavitys of sealing assembly 8 is taken away, due to by tonifying Qi path 28, supplement ambient atmosphere, make the pressure in diaphragm 32 top cavitys still maintain standard atmospheric pressure.During oiling work, when the front end of gun barrel 23 enters below fluid or when oil gun lifts, move direction ball 28 positions, air extractor vent on direction seat 29 is blocked, capital makes air supply passage 28 and ambient atmosphere isolation, diaphragm 32 top cavitys, because not continuing atmosphere supplements, under Venturi effect, thereby form the needed vacuum state of self-styled jumping rifle.
The top of oil-gas recovery self-sealing fuel oil gun body 1 as shown in Figure 1, be provided with oil pressure actuated and the vacuum generation chamber of one, wherein by capping 39, oil pressure actuated plug 40, v shaped ring 42, formed with no pressurely from sealing assembly, the oil pressure actuated plug 40 of v shaped ring 42, up-and-down movement in capping 39 are again installed.As shown in Figure 4, diaphragm 32 is installed on vacuum generation lower cover 38 belows, by joint bolt 35 and screw connection 36, the engagement key seat 33 that two engaging pins 34 are housed is connected with upper spring seat 41, between upper spring seat 41 and lower spring cup 37, be respectively arranged with oil pressure retracing spring 43 and vacuum and jump bullet spring 44, the vacuum of above-mentioned part composition nozzle is from sealing assembly.As shown in Figure 5, for the push-rod assembly 6 of the utility model nozzle, imput shaft 47 can move freely driven axle 45 is interior, by between centers bayonet lock 48, the range of movement of restriction imput shaft 47 in driven axle 45, in driven axle 45, be provided with between centers spring 46, needed restoring force while providing imput shaft 47 to reset, whole push-rod assembly 6 can move in the certain limit in the hole at rifle body 1 middle part.
In conjunction with said modules structure, below to the utility model oil-gas recovery self-sealing nozzle, specific works process during oiling and function realize and being described.When fuel charger is carried rifle, operation of oil pump, the pressure oil of oil gun inside is through capping, the aperture of 39 both sides, enter the top of oil pressure actuated plug 40, due to the effect of oil pressure, oil pressure actuated plug 39 overcomes the effect of oil pressure retracing spring 43, moves down, thereby drive, from the upper spring seat 41 of sealing assembly, move downward, diaphragm 32, under the effect of lower spring cup 37, drives engagement key seat 33 down to move, and makes two engaging pins 34 move down in the groove of driven axle 45 and the top of imput shaft 47.Now, mention the oil gun spanner 14 being connected with U-shaped support 9, the drive spindle 10 of drive in U-shaped support 9 waist shaped holes moves right, promoting imput shaft 47 moves right, due to the drive of engaging pin 34, driven axle 45 also moves right thereupon, driven axle 45 right-hand member step surfaces back down the interior main valve 5 in rifle body 1 primary valve position, make fluid through primary valve, by rifle body asphalt channel chamber 15, secondary valve valve port 19, is finally flowed out by the fluid output channel 27 in gun barrel 23, realizes the refueling operation to vehicle.When the front end of gun barrel 23 enters below fluid or when oil gun lifts, diaphragm 32 upper chamber form vacuum, due to the effect of pressure reduction, now on diaphragm 32, lift, engaging pin 34 is pulled out from the groove of driven axle 45, under the effect of oil circuit main spring 3, driven axle 45 is moved to the left, and interior main valve 5 resets, and primary valve is closed, oil stream is cut off, and realizes self-styled jumping rifle function.Compared with assisting self-styled jumping gunlock structure with traditional steel ball, self-styled jumping rifle winding machine of the present utility model is easier, and function is more reliable.When cutting off fuel charger oil pump power supply, oil pressure actuated plug 40 tops no longer include the effect of pressure oil, under the effect of oil pressure retracing spring 43, oil pressure actuated plug 40 moves up to position as shown in Figure 1, diaphragm 32 pulls out engaging pin 34 from the groove of driven axle 45, primary valve is closed, and oily stream is cut off, thereby realizes the function of self-styled jumping rifle with no pressure.And when fuel charger oil air pump inoperative, oil pressure actuated plug 40 is in position as shown in Figure 1 all the time, and engaging pin 34 is at the state of " unsettled ".Now, mention oil gun spanner 14, although imput shaft 47 can move right, because there is no the engagement of engaging pin 34, driven axle 45 can not move all the time, and the primary valve of oil gun also just cannot be opened.This can effectively prevent that primary valve is opened in the stress-free situation of dispenser system, causes the even generation of the contingency such as fire of waste of oil resources.
The utility model adopts unique gas oil separation structure, realizes the synchronous opening and closing in gas channels 53 and asphalt channel chamber 15.As shown in Figure 6, the gas circuit valve rod 51 of 2 O shape circles is housed, is installed in the hole at Oil-gas Separation plug 49 middle parts, gas circuit valve port 52 is threaded connection with gas circuit valve rod 51 fixing, between gas circuit valve rod 51 and Oil-gas Separation plug 49, gas circuit Packing spring 50 is housed.When nozzle spanner 14 is risen by plate, when primary valve is opened, outer main valve 4 promotes gas circuit valve rod 51 and moves right, and gas circuit valve port 52 is also along with moving right, and gas circuit valve port 52 is opened simultaneously.Now, oil gas, by the oil gas recycling cavity 13 on rifle body, through the gas circuit valve port in Oil-gas Separation plug 49, enters in the gas channels 53 being connected with oil gas recovery rubber tube, realize oil gas and reclaim synchronizeing of function and oil circuit on-off action, significantly improved the efficiency of nozzle oil gas recovery.
