Description
Affiliated technical field
The utility model relates to a kind of automatic sealing ZH-LLY.
Background technology
All use automatic sealing fuel charger that self-propelled vehicle is refueled in the most city of China, this equipment can show gas filed quantity by automatic fuel cutoff simultaneously on fuel charger when the fuel tank of self-propelled vehicle is filled it up with.But this equipment price costliness can only be used simple and crude relatively nozzle in some areas that fall behind relatively, and the most of function that does not have metering of nozzle in the market.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective of prior art, and a kind of nozzle that has automatic closing function and have function of measuring is provided.
The utility model comprises the rifle body, the rifle body is provided with oil inlet, oil pocket, oil outlet, main valve is arranged in oil pocket, rifle body below is provided with handle, handle and main valve are hinged, be provided with retracing spring and latching device between handle and the rifle body, near rifle body oil outlet, be provided with diaphragm valve, diaphragm valve one end is provided with air-pressure chamber, it is external and hinged with handle that the automatic control bar of diaphragm valve extends to rifle, and the oil outlet of rifle body is connected with fuel filler pipe, is provided with sebific duct in the fuel filler pipe, one end of sebific duct is communicated with the air-pressure chamber of diaphragm valve, and the other end of sebific duct is connected with the admission port of fuel filler pipe front end side wall.Technical solution of the present utility model is to be provided with impeller near the oil pocket the oil inlet in the rifle body, also is provided with worm couple in the oil pocket, and the outside of rifle body is provided with register, and impeller connects with worm screw, and worm gear and register connect by magnetic shaft coupling.
Adopt the nozzle of said structure not only to have automatic osed top function, also have the function of metering simultaneously, cost is very cheap simultaneously, is the substitute products of the desirable fuel charger in economically less developed region.
Description of drawings
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is the configuration diagram of present embodiment.
The specific embodiment
Present embodiment comprises rifle body 1, rifle body 1 is provided with oil inlet 2, oil pocket 3, oil outlet 4, main valve 5 is arranged in oil pocket 3, rifle body 1 below is provided with handle 6, the lower end of main valve 5 extends to outside the rifle body 1, elongated end and handle 6 are hinged, be provided with handle retracing spring 7 and latching device 8 between handle 6 and the rifle body 1, in rifle body 1, be provided with diaphragm valve 9 near the oil outlet 4, diaphragm valve 9 one ends are provided with air-pressure chamber 10, it is outer and hinged with handle 6 that the automatic control bar 11 of diaphragm valve 9 extends to rifle body 1, the oil outlet 4 of rifle body 1 is connected with fuel filler pipe 13, be provided with sebific duct 14 in the fuel filler pipe 13, an end of sebific duct 14 is communicated with air-pressure chamber 10, and the other end of sebific duct 14 is connected with the admission port 15 of fuel filler pipe 13 front end side wall.Be provided with impeller 16 near in rifle body 1 oil inlet 2 the oil pocket 3, also be provided with worm couple in the oil pocket 3, the outside of rifle body 1 is provided with register 17, and impeller 16 connects with worm screw 18, and worm gear 19 and register 17 connect by coupler.Coupler in the present embodiment is a magnetic shaft coupling, comprises that two 20,21, two disks 20,21 of disk that have magnetic lay respectively at the both sides of rifle body 1 wall, and one of them disk 20 is connected with worm gear 19, and another disk 21 sum counters 17 connect.
When oil gun was in closed state, main valve sealed oil pocket.Upwards pull handle, on the one hand latching device is caught on handle automatically, it can overcome the effect of handle retracing spring again on the other hand, make main valve upwards mention and open, pressure oil enters into oil pocket from the oil inlet of oil gun, enter into fuel filler pipe through oil outlet, because this moment, the admission port and the atmosphere of fuel filler pipe communicated, pressure oil enters into after the fuel filler pipe, the air that drives in the fuel filler pipe flows in container together, the outer air of pipe will enter from admission port, carry out replenishing continuously along the sebific duct internal channel, after oil level in container has flooded the admission port of oiling pipeline, can not get effectively replenishing of air in the atmosphere, having to extract from air-pressure chamber a bit, limited air replenishes, in the extremely short time, make and become negative pressure in the air-pressure chamber, diaphragm valve is popped up, the automatic control bar loses positioning action, driving handle makes handle produce a bit small rotation around the hinge-point of main valve and handle downwards, just can make latching device break away from handle in the extremely short time, effect lower handle at the handle retracing spring resets, and drive valve closing, and finished self-styled gas filed effect, stopped refueling operation.
When refueling, earlier oil gun is opened in the digital zero clearing of counting machine again, after pressure oil enters into the oil gun body, pressure oil has just promoted the impeller rotation, drive is contained in the worm screw rotation on the paddle shaft, thereby has driven the worm gear rotation, and the plectane that magnetic shaft coupling is housed between worm gear pair and the gear pair is divided into upper and lower two-layer, the rotation of worm gear drives the plectane upper strata and has driven counter works by magnetic shaft coupling, thereby just can demonstrate the gas filed numeral on the dial plate of counting machine.Because magnetic shaft coupling is two-layer not connected up and down, guaranteed the sealing property of oil gun.
Admission port is not when being flooded fully by added oil plant, in case latching device is separated with handle, handle falls under the effect of handle retracing spring automatically, and main valve is closed, and also can reach the purpose of ending refueling operation.No matter adopt which kind of mode that refueling operation is stopped, ending behind the refueling operation on the dial plate shown numerical value and be exactly the quantity of added oil plant just now.
