Description

Double needle takes spindle pipe

Technical field

The utility model relates to oils device context sampler, in particular to a kind of double needle takes spindle pipe.

Background technique

When oils equipment draws oil sample, Yao Yange avoids adulterating air in oil, otherwise will affect the judgement of test result.In mesh When advance line transformer takes oil, oil is taken usually using single needle syringe, after syringe oiling, can all there is a certain amount of sky in syringe Gas needs repeatedly to drain the bubble in needle tubing.But since transformer oil is thicker, minute bubbles flow very slowly in needle tubing, and It is more dispersed, it is not easy to drain, leads to that oily process is taken to need to operate repeatedly, even oiling again is needed to be vented sometimes, lead to wave Take transformer oil, wasting manpower and material resources take oily low efficiency.

Utility model content

In view of this, taking spindle pipe the purpose of the utility model is to provide a kind of double needle, it can be achieved that can side when taking oil The exhaust of oiling side, saves the process being vented repeatedly, time saving and energy saving.

The purpose of this utility model is achieved through the following technical solutions:

Double needle takes spindle pipe, including syringe, and the back end of syringe is provided with the push-and-pull used in conjunction with piston Bar, the front end of the syringe are provided with two groups of needle assemblies, and the needle assembly includes nipple, syringe needle and pintle, the nipple It is fixed at syringe front end, the pintle is detachably connected on nipple, and syringe needle setting is described to push away in the pintle other end The rear end of pull rod is provided with a plate press section, and the needle tubing further includes that can be placed on Supramammillary lid.

Further, elastic cushion is provided on rear side of the plate press section.

Further, the elastic cushion is semicircle head.

Further, the pintle is connected by screw thread with nipple.

The beneficial effects of the utility model are:

The double needle of the utility model takes spindle pipe, and by the way that two groups of needle assemblies are arranged, one group is used for oiling, and one group is used for Exhaust realizes the exhaust of marginal not oil side, eliminates the process being vented repeatedly, although structure is simple, achieve unexpected Effect, that is, take oily simple quick, without being vented body repeatedly, the used time is few, takes oil convenient.

Other advantages, target and feature of the utility model will be explained in the following description to a certain extent It states, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or Person can be instructed from the practice of the utility model.The target of the utility model and other advantages can be said by following Bright book is achieved and obtained.

Detailed description of the invention

It is practical to this below in conjunction with attached drawing in order to keep the purpose of this utility model, technical solution and advantage clearer It is novel to be described in further detail, in which:

FIG. 1 is a schematic structural view of the utility model.

Specific embodiment

Hereinafter reference will be made to the drawings, and the preferred embodiment of the utility model is described in detail.It should be appreciated that preferably real Example is applied only for illustrating the utility model, rather than in order to limit the protection scope of the utility model.

As shown in Figure 1, double needle takes spindle pipe, including syringe 1, scale is provided on syringe 1,1 rear end of syringe is provided with Push-pull rod 2 used in conjunction with piston, the front end of syringe are provided with two groups of needle assemblies, needle assembly include nipple 3, Syringe needle and pintle, nipple are fixed at syringe front end, and pintle is detachably connected on nipple, and syringe needle setting is another in pintle End, one group of needle assembly are used for oiling, and another group of needle assembly is used for oil extraction, and the rear end of push-pull rod 2 is provided with plate pressing Portion, needle tubing further include that can be placed on Supramammillary lid.

It is provided with elastic cushion 4 on rear side of plate press section, use is more comfortable.Preferably, elastic cushion is semicircle head, energy Further promote the comfort used.

Pintle is connected by screw thread with nipple, pintle convenient disassembly.

Needle tubing further includes that can be placed on Supramammillary lid.

When taking oil using the needle tubing, needle assembly upward, from when a needle assembly oiling, draw back automatically by push-pull rod, when When oiling reaches 40mL or more, push-pull rod is firmly resisted, by transformer oil pressure automatically by air from another group of needle assembly Middle exclusion, be discharged to it is fuel-displaced after, remove pintle with lid and seal nipple, then remove again for take oil pintle and sealed with lid Nipple takes oil to finish.

Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this The technical solution of utility model is modified or replaced equivalently, should all without departing from the objective and range of the technical program Cover in the scope of the claims of the utility model.
