Description

Self-styled nozzle

Technical field

The utility model relates to a kind of topping up device, particularly self-styled nozzle.

Background technology

Existing self-styled nozzle is made up of parts such as rifle body, Handleset, main valve, control cock, draught damper, gun stock, oil outlet pipes; Its draught damper is shaped on air extractor vent and is communicated with the control cock air cavity, and after oil was filled it up with, the breather pipe on the oil outlet pipe was blocked; The jet action of draught damper makes the control cock air cavity produce negative pressure; The drive control cock is moved, and through Handleset main valve is closed, and nozzle is suitable for the filling operation of lightweight oils such as kerosene, gasoline, diesel oil; Be melted into body of a gun design-calculated self-packer and can guarantee SELF CL oil gun when container is filled it up with, prevent that medium is excessive.

But dynamics is used difficulty inadequately when having occurred in the use now being difficult to pull the handle problem or pulling handle; Like hand-power degree not enough (wherein especially girl); The pressure oil pressure that injects is big; Motionless handle appears pulling, so need one to use simple and the self-styled nozzle in labour-saving.

The utility model content

The purpose of the utility model is convenient, the self-styled nozzle in labour-saving when for the deficiency that solves above-mentioned prior art a kind of use being provided.

To achieve these goals, the self-styled nozzle of the utility model institute design-calculated comprises the rifle body, is fixed on the oil outlet pipe on the rifle body, the oil-feed mouth of pipe, Handleset, main valve and the control cock that communicates with the rifle body; Main valve and control cock place in the rifle body; Main valve comprises valve gap, spring, flap and valve rod from top to bottom successively, and valve gap is fixed on the rifle body, and flap places on the rifle body; Spring is between flap and valve gap; Valve rod one end is connected with the flap heavy keying fit, and the other end and Handleset contact, and it is characterized in that described flap comprises flap and lower Disc.

As preferably, last flap is positioned at the top of lower Disc, and lower Disc is positioned on the rifle body; The lower end middle of last flap is equipped with the identical circular hole of diameter with lower Disc is middle, and the lower end indent circle of last flap is provided with 0 RunddichtringO, and the lower end indent circle of lower Disc is provided with netted seal ring; The flange platform of last flap upper end and an end of spring are connected; The diameter of valve stem tip section is less than the diameter of valve rod lower end section, and the valve stem tip section is passed the lower Disc circular hole, and with the circular hole matching and fixing of last flap; This scheme utilize that flap opens sequencing, make easy to use and laborsaving.

In order to reach best sealing function, the rifle body is provided with the copper seal receptacle with rifle body close-fitting, and the endoporus of copper seal receptacle cooperates with valve handle activity.

The external external cover of rifle that is arranged with of described rifle, the oil-feed mouth of pipe is provided with the sheath that cooperates with the oil-feed mouth of pipe.

The self-styled nozzle that the utility model obtains; Light when pulling Handleset when making work; Effect when not refueling to pull dynamics identical; Alleviated greatly and pulled the required weight of bearing, the pressure oil pressure that has solved existing use injection is big, so that the feasible problem of pulling the handle difficulty.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Embodiment:

Like Fig. 1, Fig. 2, shown in Figure 3, the self-styled nozzle that present embodiment provides comprises rifle body 2, is fixed on the oil outlet pipe 1 on the rifle body, the oil-feed mouth of pipe 5 that communicates with the rifle body, Handleset 4, main valve 6 and control cock 3; Main valve 6 places in the rifle body 2 with control cock 3, and main valve 6 comprises valve gap 10, spring 11, flap 12 and valve rod 13 successively from top to bottom, and valve gap 10 is fixed on the rifle body 2; Flap 12 places on the rifle body 2, and spring 11 is between flap 12 and valve gap 10, and valve rod 13 1 ends are connected with flap 12 heavy keying fit; The other end and Handleset 4 contact, and described flap 12 comprises flap 21 and lower Disc 22, and last flap 21 is positioned at the top of lower Disc 22; The lower end middle of last flap 21 is equipped with the identical circular hole of diameter with lower Disc 22 centres, and the circular hole of lower Disc 22 is through holes, and the lower end indent circle of last flap 21 is provided with O RunddichtringO 31; O RunddichtringO 31 internal diameters are 5.8mm, and external diameter is 12mm, and the lower end indent circle of lower Disc 22 is provided with netted seal ring 32; Netted sealing 32 circle internal diameters are 15.5mm, and external diameter is 25.5mm, and the flange platform of last flap 21 upper ends and an end of spring 11 are connected; The diameter of valve rod 13 top sections is less than the diameter of valve rod 13 lower end sections; Valve rod 13 lower end section diameters are greater than lower Disc 22 Circularhole diameters, and valve rod 13 top sections are passed lower Disc 22 circular holes, and with the circular hole matching and fixing of last flap 21; Rifle body 2 is provided with the copper seal receptacle 9 with rifle body close-fitting, the endoporus of
