In order to realize above-mentioned technical characteristic, what the purpose of this utility model was realized in：A kind of transformer draws oil sample
Valve nozzle, it includes sampling valve head, and the center of the sampling valve head is machined with internal thread hole, the internal thread hole and valve flowline
Male end be engaged composition and be screwed connection, the end face that the inner chamber body of the internal thread hole is engaged with valve flowline
Packing ring is provided with, the outer face of the sampling valve head is provided with coupling, is connected with out in the coupling by screw thread
Oil head, it is described go out oil head center be machined with oil duct, it is described go out oil head the oil outlet of front end connecting pole and sampling valve head match
Close, it is described go out oil head end be provided with horn-like outlet.
Sealing ring mounting groove is machined with the outer wall of the front end connecting pole, installation is inlayed inside the sealing ring mounting groove
There is sealing ring, the sealing ring fits with sampling the oil outlet inwall of valve head.
The sampling valve head is made of pure copper material, and its profile is hexagon head structure.
It is described go out oil head be made of pure copper material.
The horn-like outlet is in contact with sampling syringe needle.
Valve is installed, the other end of the valve flowline is connected with transformer mailbox on the valve flowline.
The utility model has the advantages that：
1st, draw oil sample valve nozzle by using above-mentioned transformer in the utility model, in sampling process, first, will sample
The internal thread hole of valve head is relative with valve flowline to be connect, and is tightened, and it is formed with packing ring and is sealed, while will go out oil head and pass through spiral shell
Line is fixedly connected on the oil outlet of sampling valve head, after installing fixed complete, passes through Open valve, the fluid of inside transformer
The oil duct of oil head will be reached out by oil-out, and is flowed out eventually through horn-like outlet, now horn-like outlet can be very
Good is in contact with sampling syringe needle, more transformer oil of avoiding waste.
2nd, can be to being effectively sealed between valve flowline and sampling valve head by described packing ring, and then ensure
Sealing effectiveness, prevents the fluid from being leaked from gap.
3rd, fluid can be made to smoothly enter oil duct by the cooperation between described front end connecting pole and sampling valve head
Inside, and fluid can be sealed by described sealing ring, prevent it from being leaked from gap.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is main sectional view of the present utility model.
In figure：Oil-out 1, valve 2, valve flowline 3, sampling valve head 4, internal thread hole 5, packing ring 6, front end connecting pole 7,
Coupling 8, go out oil head 9, oil duct 10, horn-like outlet 11, sealing ring 12.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
The valve nozzle as shown in figure 1, a kind of transformer draws oil sample, it includes sampling valve head 4, and the center of the sampling valve head 4 adds
Work has an internal thread hole 5, and the internal thread hole 5, which with the male end of valve flowline 3 is engaged composition and is screwed, to be connected, described
The inner chamber body of internal thread hole 5 is provided with packing ring 6 with the end face that valve flowline 3 is engaged, and the outer face of the sampling valve head 4 is set
Be equipped with coupling 8, oil head 9 be connected with out by screw thread in the coupling 8, it is described go out oil head 9 center be machined with oil
Road 10, it is described go out oil head 9 front end connecting pole 7 with sample valve head 4 oil outlet be engaged, it is described go out oil head 9 end set
There is horn-like outlet 11.Conveniently transformer can be carried out taking oily operation by above-mentioned device, and ensure that and take
Oily effect.
Further, sealing ring mounting groove is machined with the outer wall of the front end connecting pole 7, in the sealing ring mounting groove
Portion, which inlays, is provided with sealing ring 12, and the sealing ring 12 fits with sampling the oil outlet inwall of valve head 4.By using sealing ring
